Statement on Failure of “Right to Try” Bill

Diana Zuckerman, PhD, National Center for Health Research, March 13, 2018

We thank the Members of the House of Representatives who voted against the misleadingly named Right to Try bill yesterday, because they understood that the bill would have done so much more harm than good for desperate patients.  The bill would not improve access to experimental treatments for which there is any real hope of benefit to seriously ill patients.  Instead, it would set up a new, untested program that would enable desperate patients to purchase drugs for which there is no evidence that they would help patients live longer or even temporarily feel  better.  Worse, these drugs could cause painful, debilitating deaths, with virtually no protections in place for patients.

We know that some patients are willing to try anything.  Unfortunately, 85% of the drugs that would become available through the Right to Try legislation are expected to be later proven to be not safe and not effective.

An effective program is already in place for patients who don’t qualify for clinical trials but want to try experimental drugs for which there is at least some small evidence of possible benefit.  That program is called “Expanded Access” or “compassionate use.”  It has been in existence for years and it works.  We urge all Members of Congress to learn more about that program and consider how to strengthen it, instead of being persuaded by false promises of false hope.

And be sure to also listen to the loved ones of patients who have been harmed by experimental drugs.  There are many more of them  than there are of patients helped by Right to Try legislation that has already passed in most states.

NCHR Letter to Maryland on State Funding for Artificial Turf and Playgrounds

Diana Zuckerman, PhD, National Center for Health Research, March 5, 2018

To: The Honorable Governor Larry Hogan
The Honorable Mike Busch, Speaker, Maryland House of Delegates
The Honorable Thomas V. Mike Miller, President, Maryland Senate
The Honorable Maggie McIntosh, Chair, House Appropriations Committee
The Honorable Edward Kasemeyer, Chair, Senate Budget and Taxation Committee

Delegate Aruna Miller
Senator Roger Manno

Subject: State funding for synthetic (artificial) turf and playgrounds (HB 505, SB 763)

As president of the National Center for Health Research (NCHR) a resident of Montgomery
County for more than 25 years, and the former Chair of the Governor’s Women’s Health
Promotion Council, I strongly support HB 505 and SB 763 to prohibit the use of state funds for artificial turf fields and similarly dangerous playground materials. NCHR conducts research and helps consumers and policy makers understand scientific evidence that can be used to improve programs and policies that affect the health of adults and children. We do not accept any funds from drug or medical device industry sources. And, as a public health expert and parent of two children raised in Maryland, my focus is how we can keep our children safe and healthy.

Artificial turf is made from synthetic rubber, plastic, and other materials with known health risks. For example, the widely used material known as crumb rubber includes cancer-causing agents as well as chemicals that disrupt our bodies’ hormones. These are called endocrine-disrupting chemicals, and studies show that they contribute to early puberty, obesity, and attention deficit disorder. Since endocrine-disrupting chemicals have been banned from rubber duckies, teething toys, and other products children use for a relatively short period of time, it makes no sense for the State of Maryland to spend millions of dollars on playing fields and playgrounds that will expose our children to those same types of banned chemicals day after day, year after year.

The artificial turf industry and those that have financial and personal ties to them tell us that there is no clear evidence that their fields caused any child to develop cancer or any other disease. They also state that the Consumer Product Safety Commission (CPSC) and the Environmental Protection Agency (EPA) have declared these materials as safe for use in
playgrounds or athletic fields. Those statements are misleading. CPSC has conducted recent workshops on the topic attended by invited scientific and public health experts, but neither CPSC nor EPA have concluded that these products are safe.

In February 2016, the U.S. government announced a new action plan to better understand the likely health risk of recycled tire crumb and similar artificial surfaces. This initiative involves the Center for Disease Prevention and Control (CDC); the Agency for Toxic Substances and Disease registry (ATSDR); and CPSC. No results are yet available and given the anti-regulatory focus of the current federal administration, we do not expect any new restrictions in the near future. That makes the actions of Maryland even more important.

Meanwhile, various reliable science-based studies from the California Office of Environmental Health and Yale University, among others, have found dozens of harmful chemical in tire crumb used in these playing surfaces. In addition to the impact of those chemicals on children’s hormones and development, as mentioned above, tests have shown that artificial turf and playground materials can cause skin and eye irritation as well as asthma. The surface temperature can rise above 140 degrees even when the temperature of the air and grass is between 65 and 95 degrees. Recent testimony before the Maryland House Appropriations Committee provided striking examples of children suffering serious burns and MRSA-infected abrasions from artificial turf. In fact, players’ preferences and concerns about injuries helped convince the Ravens to switch back from artificial turf to natural grass several years ago.

In summary, those who manufacture or install artificial turf, and scientists and others with
financial and personal connections to those industries, have made safety claims that are not supported by any unbiased research. Even when they admit problems with tire crumb, they claim that newer types of artificial turf are safer. Unfortunately, some of the materials used in the newer types of artificial turf are not publicly disclosed, making safety claims meaningless and safety research all but impossible.

The State of Maryland has many spending priorities and should not be spending millions of
dollars for artificial turf fields and playgrounds that can exacerbate our children’s health
problems now, and potentially cause them to develop cancer in the years to come. Let’s instead invest in safe, natural playing fields, unless any synthetic alternatives are proven in unbiased research to be as safe and as cost-effective as grass for fields and engineered wood fiber for playgrounds.

Thank you for considering our views. We would be glad to supply additional information upon request.

Sincerely,

NCHR Letter to House Energy and Commerce Committee on Right To Try Legislation

National Center for Health Research, February 22, 2018

Dear Members of the House Energy and Commerce Committee,

As a research center that advocates for the best medical treatments for all Americans, we strongly believe that terminally ill patients should have access to potentially life-saving medical treatments.  Some terminally ill patients are willing to take big risks to have a chance to live longer, and if they want access to experimental treatments that are undergoing clinical trials, they should be able to do so as long as they are well informed of the risks as well as the possible benefits.

Unfortunately, many of us know desperate patients whose efforts to “try anything” made their remaining days miserable and left their families even more devastated.  What can and should Congress do to make sure that desperate patients won’t be exploited, or suffer even more painful deaths as a result of legislation?  That is the key question as you consider Right to Try legislation.

A key issue for Congress to consider is whether legislation should provide access to experimental treatments that have been in only one or two preliminary clinical trials. The earliest clinical trials (known as Phase I) often don’t include even one patient.  Instead Phase I trials can include “healthy volunteers,” such as college students, who are much less likely to be harmed by an experimental drug or device than a terminally ill patient would.

In addition, these first (Phase I) clinical trials study very small numbers of people, and do not study whether or not a medical product works.  They are designed to determine the immediate risks on just a few healthy volunteers or patients.  Since so few people are studied, even if a treatment is immediately and painfully fatal to 5-10% of patients, for example, these first clinical trials probably would not be able to provide that crucial information.

There are several Right to Try bills under consideration.  For example, the Right to Try bill introduced by Representatives Griffith and Brat (HR 1020) does not even require that a first (Phase 1) clinical trial be completed – it can have just started.  In other words, the experimental treatment could be fatal to many patients and it would be impossible to know that, or to warn patients about it.  That bill also completely restricts any oversight by FDA, and prohibits the agency from requiring the collection or disclosure of any information generated by the experimental drug therapy.  This lack of disclosure is especially problematic since the bill would protect manufacturers and suppliers of such drugs from liability except in cases of “gross negligence or willful misconduct.”

The Johnson Right to Try bill (S 204) requires that a Phase I clinical trial be completed.  That is an improvement over the Griffith and Brat bill, but 85% of drugs that successfully complete Phase I clinical trials are later found to be unsafe or ineffective and are therefore never sold in the U.S. or other countries.  So neither of these Right to Try bills would help most patients, and could potentially be fatal to many patients.  The Senate bill also restricts liability to any participant, except instances of “reckless or willful misconduct, gross negligence, or an intentional tort under any applicable State law.”  The bill directs that an annual summary of the use of any such experimental drug be provided to the HSS Secretary’s Office for later posting on the FDA web site.

In contrast, the FDA’s current Expanded Access program requires at least some evidence that an experimental treatment might possibly be helpful.  That’s not a very restrictive safeguard, but it helps protect many patients.  The FDA routinely utilizes what the agency terms “compassionate waivers” for very ill patients when doctors request them, and FDA grants such requests 99% of the time.

Another important issue for Congress to consider is whether these bills would exploit patients financially.  The experimental drugs provided through the current FDA Expanded Access program are provided for free most of the time, or “at cost.”  Clinical trials also usually provide experimental treatments for free.  The Johnson Senate bill also protects patients from financial exploitation by limiting what experimental treatments can cost.

The Griffith and Brat bill does not allow restrictions on the cost of experimental drugs, thus by such omission allowing companies to charge whatever they want to dying patients desperate for access to any experimental drug or device – even one that has absolutely no evidence that it is either safe or effective.  That means that desperate patients could be required to pay exorbitant fees for the “Right to Try” to be treated like guinea pigs.  That is unfair to families that do pay for these experimental treatments and it is also likely to induce tremendous guilt for families that could not afford to do so.

FDA’s Compassionate Use program could be improved, and improvements are already underway thanks to the Navigator program that the FDA has recently initiated with the Congressionally- created Reagan Udall Foundation.  However, with or without Right to Try legislation, access to experimental drugs will also be limited if patients want drugs that are not yet being manufactured in large numbers, or if reputable pharmaceutical companies are reluctant to provide drugs that they fear will be harmful to patients who are too ill to benefit.

The GAO’s July 2017 report on the FDA’s current Compassionate Use/Expanded Access program was generally supportive, with a few recommendations for improvement.  Importantly, GAO pointed out that most experimental drugs that pharmaceutical companies allow to be distributed under FDA’s Expanded Access eventually obtain FDA approval.  In other words, the program is doing what was intended – giving patients earlier (usually free) access to experimental drugs that will eventually be proven safe and effective.

In addition to harming individual patients, Right to Try legislation that makes unsafe treatments available for sale harms our entire drug development enterprise, by eliminating the incentive for patients to participate in clinical trials that would help millions of patients in the future.  If HR 1020 was to become law, then it is likely that the richest patients will buy access to experimental treatments and only the middle-class and low-income patients will participate in clinical trials.

Reputable companies would continue to study new drugs and devices in clinical trials, but progress would be slowed because of difficulty attracting enough patients to participate in clinical trials.  Meanwhile, scam artists and fly-by-night companies would be motivated to make as much money as possible on dangerous or worthless experimental drugs for as long as they are available, and HR 1020 and would make it impossible to gather information about how dangerous or ineffective the experimental drugs might be unless the sponsoring company volunteers that information.

It is well documented that unproven treatments have been sold to dying patients at outrageously high prices in Mexico and elsewhere, and many patients have been irreparably harmed or killed by unproven treatments that were marketed dishonestly.  Indeed, FDA was created to avoid the tragedies arising from the “right to try” unregulated medical sales of the 19th Century and early 20th Century.

To improve Right to Try legislation, Congress should:

  1. Ensure that experimental treatments cannot be sold at a profit by companies or medical professionals;
  2. Ensure that all experimental treatments have been proven safe in completed Phase I or Phase II trials conducted on a reasonable number of patients (not healthy volunteers);
  3. All experimental drugs and devices available through RTT should also be studied in clinical trials as part of FDA’s regulatory process;
  4. Information about harmful side effects and adverse events should be required to be reported to the FDA by the physicians.

We’d be glad to provide additional information upon request.  The National Center for Health Research is a non-profit organization which analyzes medical and scientific data and produces original health-related research to inform patients, the general public, and policymakers.  We advocate for patients and consumers to have access to safe, effective, and affordable drugs and medical devices.  We accept no funding from the pharmaceutical or medical device industries.

NCHR Comments to FDA on Nicotine Replacement Therapy (NRT) Product Uses and Labeling Changes

National Center for Health Research’s Public Comment on NRT

[Docket no.FDA-2017-N-6529]

Thank you for the opportunity to provide comments on FDA’s evaluation of nicotine replacement therapy (NRT) products, including product labeling. The National Center for Health Research (NCHR) is a nonprofit research center focused on research, policies, and programs that affect public health. Our Center analyzes scientific and medical data and provides objective health information to patients, providers, and policymakers. We do not accept funding from companies that make medical products, so we have no conflicts of interest.

According to the National Health Interview Survey (NHIS), our nation’s effort to reduce smoking has reached a plateau of around 15 percent of American adults1.  Based on early data from the the landmark 1994 Lancet meta-analysis, nicotine replacement (NRT) products are about 70% effective at achieving abstinence up to about 12 months2. However, it remains unclear whether individual achievement of abstinence is sustainable over time and whether long-term NRT use is more or less beneficial on an individual or population health level. We commend the FDA for addressing their role in developing strategies to evaluate NRT products and labeling. We agree that urgent action is necessary and the FDA should consider science-based approaches to reduce further harm from combustible tobacco products.

In consideration of the FDA’s request for public comment, we will focus our remarks on two specific questions–question 3 and question 6.

Questions 3: What data would be required to demonstrate health benefits of reduction in consumption of combustible tobacco products?   

According the U.S. Surgeon General3, we know that smoking contributes significantly to the development of cancer, including cancer of the mouth and throat, esophagus, trachea/bronchus/lung, stomach, liver, pancreas, kidney, cervix, bladder, and colon and rectum. Smoking also increases cancer mortality risk and other cause-specific mortality risk in patients with a history of cancer. We also know that smoking is linked to a number of serious chronic diseases including heart disease, stroke, chronic obstructive lung disease and asthma, diabetes, rheumatoid arthritis, blindness, reproductive defects, ectopic pregnancy, and immune dysfunction. Given the magnitude of harms, there is no doubt that reducing the use of combustible tobacco products is beneficial for individual and population health.

Retrospective analysis of the data indicates that reduction in smoking from 1964 to 2012 averted about 8 million premature smoking-related deaths from all causes4.  Modeling analysis of the short term impacts of smoking with respect to cardiovascular events demonstrate that a one-time 1% decrease in smoking prevalence prevents about 1000 heart attacks and about 500 strokes per year5. Since heart attacks are the leading cause of death and strokes cause substantial disability, these reductions are significant. Short-term impact, such as those seen in the cardiovascular modeling study, can be studied prospectively in identified patient populations. For example, smoking cessation is built into the algorithm for perioperative cardiovascular risk reduction, which may represent an ideal population to follow prospectively in order to gather meaningful data on cardiovascular morbidity and mortality.

However, assessing long-term risk reduction may prove more difficult.  For example, there is a substantial lag in the cumulative effect of tobacco exposure and development of cancers. It will likely take decades to see the full health benefits of tobacco reduction and/or cessation. Therefore, prospective studies are limited in their feasibility for answering the question at hand.

Questions 6: …FDA has recommended the labeling on OTC NRT products be modified to include the following: “If you feel you need to use [the NRT product] for a longer period to keep from smoking, talk to your health care provider.” What is the impact of longer term NRT treatment? What is the impact on likelihood of cessation or relapse prevention? What data would support an affirmative recommendation to use approved OTC NRT products for durations that exceed those currently included…or would support a chronic or maintenance drug treatment indication for such products?

Early studies of NRT products estimate that they are about 70% effective at achieving abstinence up to about 12 months. However, it remains unclear whether maintenance use of NRT products provides added benefit, or whether it increases or decreases potential harm. A 2015 study in JAMA6, comparing standard NRT therapy (8 weeks), extended therapy (24 weeks), and maintenance therapy (52 weeks), concluded that maintenance NRT use did not provide additional benefit. While NRT therapy was shown to delay time to relapse, other research indicates that continued use of NRT products after relapse did not predict a return to abstinence7. Additional data from randomized trials are needed to establish effectiveness and safety of long-term NRT use.

Moreover, long-term exposure to nicotine in NRT products may pose serious harms. A 2017 systematic review found that most studies have assessed relatively short-term exposure to NRT (about 12 weeks or fewer)8. However, the systematic review identified a UK epidemiological study which estimated a small, but significant absolute risk of 3 cases of respiratory abnormalities in 1000 live births8,9.  Such a risk must be considered for labeling regarding use by women who are pregnant or could become pregnant. In addition, a historical cohort from the UK10 found that nicotine exposure from NRT was significantly associated with higher risk of heart disease or stroke and decreased survival over a 52-week follow-up period.

Given the insufficient evidence supporting long-term or chronic use and lack of evidence ensuring safe long-term use of NRT products, we strongly oppose the proposed label modification. In addition, healthcare providers have limited experience in the use of NRT. National data indicate that health care providers assess smoking about two-thirds of the time, but recommend drug therapy less than 2% of the time11. Therefore, more data are needed on providers’ knowledge and perceptions of NRT products to determine why they so rarely recommend them and how guidance from healthcare professionals regarding NRT could be improved. In order for healthcare providers to have an educated and informed discussion with patients about long-term use of NRT, more evidence is needed to determine whether the benefits of long-term NRT outweigh potential harms.    

Thank you for the opportunity to share our perspective.

Testimony of Dr. Diana Zuckerman Before the Maryland House of Delegates Appropriations Committee on the Health Risks of Artificial Turf

Diana Zuckerman, PhD, Cancer Prevention and Treatment Fund, February 8, 2018

I am Dr. Diana Zuckerman and I am here today as the president of the National Center for Health Research and as a resident of Montgomery County for more than 25 years.  My children grew up in the county and so this is an issue of great importance to me personally as well as professionally.

I congratulate you on introducing HB 505, to prohibit the use of state funds for artificial turf fields and playgrounds, and I strongly support it.  Public funds should not be used for artificial turf and similarly dangerous playground materials.

There is considerable misunderstanding about the safety and cost-effectiveness of recycled tire material, other synthetic rubber, plastics, triclosan, and other synthetic materials on playing fields and playgrounds.  Your focus today is on whether state funding should be used to install and refurbish these artificial fields.  You will hear from others about the fact that these artificial fields are not cost-effective.  Since my training is in epidemiology and public health, I will focus on why investing in artificial turf fields is bad for our children’s health.

Artificial turf is made from synthetic rubber, plastic, and other materials with known health risks.  For example, the widely used material known as crumb rubber or tire crumb includes carcinogens as well as chemicals that disrupt our body’s hormones. These are called endocrine disrupting chemicals, and studies show that they contribute to early puberty, obesity, and attention deficit disorder.  Since breast cancer and several other cancers are fed by estrogen and other hormones, these materials can also cause cancer in the long-term.

Some endocrine disrupting chemicals have been banned by Federal law from toys and other products for young children.  It does not make sense that chemicals banned from rubber duckies, teething toys, and other products used for a relatively short period of time by children are allowed in playing fields and playgrounds where children are exposed day after day, week after week, and year after year.

The artificial turf industry will tell you that there is no clear evidence that their fields caused any child to develop cancer.  That is true.  But as an epidemiologist, I can also tell you that for decades there was no evidence that smoking caused cancer or that Agent Orange caused cancer.  It takes many years to develop that evidence.  And even then, it is usually impossible to prove that the cancer that any individual has developed was specifically caused by smoking or any other one source of exposure.  However, the weight of the evidence can be clear, even when the specific cause and effect can’t be proven.  There is clear evidence that the materials used in synthetic turf can cause cancer, skin irritation, contribute to obesity, and other health issues.

Artificial grass fields are just part of the problem.  Rubber playground materials used to cover the ground near slides, swings, and other playground equipment are attractive and seem safe, but they are made with the same kind of tire crumb and “virgin rubber” as athletic fields and have the same risks.  At a local park I recently saw particles of synthetic rubber and other potentially harmful material break off – it looks like candy and can end up in children’s mouths, as well as up their noses, in their ears, and on their clothes.  A much safer alternative, which is also ADA-compliant, is engineered wood fiber, which is just as effective as softening any falls and has no dangerous chemicals.

What the Scientific Studies Say

The California Office of Environmental Health Hazard Assessment (OEHHA) conducted three laboratory studies to investigate the potential health risks to children from playground surfaces made from recycled tires. One study evaluated the level of chemicals released that could cause harm to children after they have had contact with loose tire shreds, either by eating them or by touching them and then touching their mouth. The other two studies looked at the risk of injury from falls on playground surfaces made from recycled tires compared to wood chips, and whether recycled tire shreds could contaminate air or water.[1]

It would not be ethical to ask children to eat tire shreds, so the researchers created chemical solution that mimicked the conditions of a child’s stomach and placed 10 grams of tire shreds in it for 21 hours at a temperature of 37°C. Researchers then measured the level of released chemicals in the solution and compared them to levels EPA considered risky. The study also mimicked a child touching the tire shreds and then touching her mouth by wiping recycled tire playground surfaces and measuring chemical levels on the wipes. To evaluate skin contact alone, the researchers tested guinea pigs to see if rubber tire playground samples caused any health problems. This study assumed that children would be using the playground from the ages of 1 through 12. Results of the OEHHA studies showed that a single incident of eating or touching tire shreds would probably not harm a child’s health, but repeated or long-term exposure might. Five chemicals, including four PAHs, were found on wipe samples. One of the PAHs, “chrysene,” was higher than the risk level established by the OEHHA, and therefore, could possibly increase the chances of a child developing cancer.[1]

Out of the 32 playgrounds surfaced in recycled tires that the researchers in California looked at, only 10 met that state’s standard for “head impact safety” to reduce brain injury and other serious harm in children who fall while playing. In contrast, all five surfaces made of wood chips met the safety standard.[1]

A 2012 study analyzing rubber mulch taken from children’s playgrounds found harmful chemicals in all of them, often at high levels.[2] Twenty-one samples were collected from 9 playgrounds, and the results showed that all samples contained at least one hazardous chemical, and most contained high concentrations of several PAHs. Several of the identified PAHs can be released into the air by heat, and when that happens children are likely to inhale them. While the heat needed to do this was very high in some cases (140 degrees Fahrenheit), many of the chemicals also became airborne at a much lower temperature of 77 ºF.  And since rubber playgrounds retain much more heat than grass or dirt, a temperature of 140 degrees can happen even on a sunny spring, summer, or fall day when the temperature near grass is only 70 degrees.  The authors concluded that the use of rubber recycled tires on playgrounds “should be restricted or even prohibited in some cases.”[2]

A 2015 report by Yale scientists analyzed the chemicals found in 5 samples of tire crumbs from 5 different companies that install school athletic fields, and 9 different samples taken from 9 different unopened bags of playground rubber mulch. The researchers detected 96 chemicals in the samples. A little under a half have never been studied for their health effects, so their risks are unknown, and the other chemicals have been tested for health effects, but those tests were not thorough. Based on the studies that were done, 20% of the chemicals that had been tested are considered to probably can cause cancer, and 40% are irritants that can cause breathing problems such as asthma, and/or can irritate skin or eyes. [3]

What the EPA Has Done

The EPA created a working group that collected and analyzed data from playgrounds and artificial turf fields that used recycled tire material. Samples were collected at six turf fields and two playgrounds in four study sites (Maryland, North Carolina, Georgia and Ohio). In a report released in 2009, the agency concluded that the level of chemicals monitored in the study and detected in the samples were “below levels of concern.” However, there were limitations to this study because they did not measure the concentration of organic chemicals that are known to vaporize during summer heat, such as PAHs.

Due to the small number of samples and sampling sites used, the EPA stated that it is not possible to know if these findings are typical of other playgrounds or fields until additional studies are conducted.[4]  When announcing the results of the study, EPA joined other organizations in recommending that as a precaution, young children wash their hands frequently after playing outside.[4]

A meeting was then convened by the EPA in 2010, bringing together various state and federal agencies to discuss safe levels of chemical exposure on playgrounds made from recycled tire rubber, and opportunities for additional research.[4] In the case of PAHs, the EPA has concluded that while there are currently no human studies available to determine their effects at various levels, based on laboratory findings, “breathing PAHs and skin contact seem to be associated with cancer in humans.” [5]

In February 2016, the U.S. government announced a new action plan to better understand the likely health risks of recycled tire crumb and similar artificial surfaces. This initiative involves 4 U.S. government agencies: the EPA, Centers for Disease Control and Prevention (CDC), Agency for Toxic Substances and Disease Registry (ATSDR) and Consumer Product and Safety Commission (CPSC).  However, I’m sure many of you are aware that the current EPA is unlikely to complete the analysis in an objective, scientific way.

In summary, it is essential that the State of Maryland stop paying for artificial turf fields and playgrounds that can clearly exacerbate our children’s existing health problems and cause new  health problems. Let’s instead invest in safe, natural playing fields, unless any artificial alternatives are proven to be safer, more effective, and as cost-effective as grass.

Health Insurance: It’s Open Enrollment Season – Now What?


If you don’t have health insurance, or want a new plan, you can use the Obamacare Health Insurance Marketplace to get coverage. If your employer doesn’t provide affordable health insurance, the prices are likely to be better through Obamacare (also called the Affordable Care Act).

Each year, health insurance companies make changes to their benefits, premiums, deductibles, and copayments. During open enrollment, you can enroll in a health insurance plan that fits your needs.

Open enrollment for Obamacare is from November 1 – December 15. Only 7 states (California, Colorado,  MassachusettsMinnesotaNew YorkRhode Island,  Washington, and the District of Columbia) have slightly longer open enrollment. However, many other insurance plans, including workplace plans, individual plans, and Medicare, also have open enrollment at the same time of year.

If you already have health insurance, it’s important to use open enrollment to review your plan’s coverage. You can check that it still meets your needs and change it if needed.

Why is the Open Enrollment Period so Important?

Open enrollment is when you can look around to make sure you aren’t paying more than necessary for good health insurance. Make sure you will be getting the services and benefits you need.

If you were enrolled in a plan in 2018, you will be automatically re-enrolled in 2019 for the same or similar plan. But, that plan could be more expensive or may not cover the services you need. You will not be able to change this plan once the open enrollment period ends, so don’t let yourself be automatically re-enrolled unless you are sure that the policy is what you want.

You can also use open enrollment to get health insurance for the first time. The law requires you to have health insurance, and the penalty goes up every year. In 2019, you can face a minimum fine of $695 or 2.5% of your income (whichever is higher), and up to $2,085 if you don’t have health insurance.

You can get your insurance through the Affordable Care Act (“Obamacare”) on healthcare.gov (sometimes called the marketplace or the exchange).

Health insurance might also be offered through your job or your spouse’s job. Most employers will send out reminders about open enrollment and set aside a two-week period for reviewing the available health plans.

Whether you already had a health plan this year or not, here are some basic tips you should think about for 2019:

  • Do your homework. Reviewing your options could save you hundreds or thousands of dollars. Even if you liked your plan this year, it might not be the best choice for next year. And, it might be cheaper for your children to be on your spouse’s insurance plan instead of yours.
  • Double-check that the medications you are taking and the doctors you see are covered by the plan you choose. Choosing a cheaper plan could cost you more in the long run if your doctor is out-of-network or if your plan doesn’t cover something you need, such as a smoking cessation drug. Most insurance companies have a website where you can check which doctors and medications are covered.
  • Check that the services you need are covered. Are you going to need specific services that some insurance plans exclude, such as bariatric surgery, certain types of counseling or smoking cessation programs, or surgery to fix complications from cosmetic surgery? These exclusions are often hard to find – and you may not know they aren’t covered until you need them and get denied. Before signing up, you should call the insurance company to find out what is covered and what isn’t.
  • Don’t forget about vision and dental plans. These plans cover preventive services like eye exams and teeth cleaning. Some plans include dental benefits. You can also buy these plans separately through the exchange. Some plans on the exchange include vision benefits. If your insurance is covering anyone under the age of 18, they must offer dental and vision coverage. Routinely getting your teeth and eyes checked could help prevent more serious medical problems down the road. On the other hand, these plans might cost more than they are worth to you, so consider your own needs before deciding.

If you’re buying an insurance plan through healthcare.gov or state exchange websites:

  • Update your household and income information. You might be able to save money compared to last year.
  • Check that the plan covers what you need. Even if you were automatically enrolled, the plan might be different than last year.

Open Enrollment for 2019 Health Insurance

If you’re buying health insurance for 2019 through healthcare.gov, here are the important dates:

November 1, 2019: The first day you can enroll in a 2019 insurance plan.

December 15, 2019: The last date to enroll for coverage that starts January 1, 2019*. If you miss this deadline, you can’t sign up for a health plan for the rest of 2018. The only exception is if you qualify for a Special Enrollment Period, if you lose your health insurance, get married, or have a baby. Click here to learn more about the Special Enrollment Period. If you don’t change or re-enroll in a plan, you will automatically be enrolled into the same or a similar plan as you were this year. You will not be able to change this plan after the open enrollment period ends, even if it costs more or includes different coverage, so be sure to decide what you want to do before Dec 15.

If you live in California, Colorado,  MassachusettsMinnesotaNew YorkRhode Island,  Washington, and the District of Columbia, you have a little extra time to sign up.

January 1, 2019: The date your 2010 coverage starts if you enrolled or changed plans by December 15. If you live in one of the 5 states listed above, or Washington, D.C., you should check to see when your coverage would start.

Remember:

  • Coverage is affordable: The tax credit through healthcare.gov reduces most people’s premiums to be between $50 and $100 per month. Last year, 8 out of 10 people qualified for this reduction. Make sure to check your options to see how much the co-payments and deductibles are.
  • Cost-sharing reductions (CSR) are still available: Subsidies are available for people who have an income of 100%-250% of the federal poverty level. CSR are only available in Silver plans. Insurers raised monthly premiums because the Trump Administration stopped reimbursing them, but insurance companies are still required to discount those costs for many consumers.
  • Signing up for coverage is easy: It takes about 10 minutes to submit an application. You can even sign up on your smartphone! Out-of-pocket cost estimators like this one can help you estimate your total healthcare costs for the year including premiums, deductibles, and co-pays. There are tools to help you look up doctors and prescription drugs, so you can figure out which plans will cover your needs
  • Start early: The healthcare.gov website will be closed for 5 out of the 6 Sundays from midnight to noon EST during the open enrollment period, and there will be surges in the number of people trying to sign up on some days, especially in December.
  • Free, expert help is available: Free, anonymous help is available 24/7 if you want to talk to someone about your options or if you have questions about signing up. You can call 1-800-318-2596 or you can find local help by searching on HealthCare.gov.
  • If you don’t sign up by December 15th, you may have to pay a penalty: The minimum penalty for not having health insurance is $695 or 2.5% of your income (whichever is higher), but the fine can be up to $2,085.

NCHR Comments on the USPSTF’s Evidence Review and Draft Recommendation Statement for Behavioral Counseling for Skin Cancer Prevention

National Center for Health Research: November 6, 2017

Thank you for the opportunity to express our views about the USPSTF’s evidence review and draft recommendation statement on behavioral counseling interventions for skin cancer prevention. The National Center for Health Research is a nonprofit think tank that conducts, analyzes, and scrutinizes research, policies, and programs on a range of issues related to health and safety. We do not accept funding from companies that make products that are the subject of our work.

Skin cancer prevention is a very important public health issue, and the public needs better information. The USPSTF previously cited evidence linking UV radiation exposure to an increased risk for melanoma later in life for children, and to a lesser extent, adults. Encouraging healthy sun-related behaviors that prevent UV exposure, and ultimately skin cancer, would save lives.

We support the efforts of the U.S. Preventive Services Task Force (USPSTF) to re-evaluate its recommendations in light of new research regarding behavioral counseling interventions to prevent skin cancer. We have a few comments regarding the draft recommendations:

#1: Based on new studies of children younger than 10 years old, we agree that there is sufficient evidence for USPSTF to expand their “B” grade recommendation for fair-skinned individuals from 10-24 years to 6 months-24 years.

#2: We agree with a “C” grade recommendation for fair-skinned adults older than 24 instead of an “I” grade. This means that discussion about behavioral counseling will be left to doctors and patients to decide based on doctors’ professional judgment and patients’ preferences. Some studies indicated that adults benefited from behavioral counseling interventions, particularly for interventions that were longer and more involved (e.g. sun protection-focused text messages over 12 months vs. single behavioral counseling session).

#3: We concur with maintaining an “I” grade for skin self-examination as the review team did not find any eligible studies to evaluate.

#4: Available data present challenges to making recommendations. For example, studies were not sufficiently long-term to study the incidence of skin cancer outcomes. Two adult studies followed patients for 24 months, but most studies only followed patients for 3-13 months. We agree that, ideally, additional studies are needed to assess skin cancer outcomes over a much longer period of time. We also recognize that it is not feasible to study the impact of these interventions long-term and agree with the USPSTF’s focus on reviewing behavioral counseling interventions aimed at promoting sun-protective behaviors that prevent individuals’ exposure to UV radiation in the short-term.

#5: Future reviews and recommendations should expand the recommendations to include people who do not have fair skin and light-colored hair and eyes. Although white people have the highest risk of melanoma and were overwhelmingly represented in this review, researchers noted that it is unknown whether these findings also apply to people of color, who die at higher rates from skin cancer. In addition, it would be beneficial to know if the benefits and risks were similar between men and women and for those who have family members who developed skin cancer.

#6: Studies are needed to determine which, if any, primary care-related interventions are effective for which demographic subgroups. Researchers concluded that successful behavioral counseling interventions were typically multi-component, including varying combinations of intervention components such as in-person counseling, print media, and sun protection aids like sunscreen.

In conclusion, we support USPSTF’s draft recommendations for behavioral counseling interventions to prevent skin cancer as well as their broader efforts to improve the health of all Americans by making evidence-based recommendations about clinical preventive services. As more information becomes available, we encourage the provision of additional recommendations about more specific behavioral interventions to prevent skin cancer for individuals in various subgroups.

NCHR Letter to the DC City Council on Artificial Turf

National Center for Health Research: October 26, 2017

Dear Council Members,

I am writing to respond to the request for additional information from Councilwoman Cheh as follow-up to my statement and the written materials I provided at the October 13 roundtable on artificial turf.

As the president of the National Center for Health Research, I expressed my strong concerns about the safety of the synthetic turf that the city has used and is continuing to use.  As a scientist who has worked on health policy issues for more than 30 years, I don’t shock easily.  However, the fact that school athletic fields and playgrounds are exposing D.C. children on a daily basis to chemicals and materials that are known to increase obesity; contribute to early puberty; cause attention problems such as ADD; harbor deadly bacteria; and exacerbate asthma is very disturbing.  Surely these are exactly the types of health problems that the D.C. government should be doing its best to reduce, not increase.

Federal agencies were investigating the safety of these products during the Obama Administration and were close to completion when the Trump Administration took over the two federal agencies involved, the Environmental Protection Agency and the Consumer Product Safety Commission.  Despite claims to the contrary at the October roundtable, neither agency has concluded that artificial turf is safe.  However, it is clear that we can’t depend on the Trump Administration to scrutinize the science regarding these products in a way that will be credible, and that means more work for the rest of us who care about children’s safety.

Envirofill and Other Hot Artificial Turf

As noted at the roundtable, all types of turf have risks and benefits, including natural grass.  However, some materials are well known to have substantial risks.  For example, DCPS is installed synthetic turf with Envirofill at Janney Elementary.  Although it is advertised as “cooler” and safer than older types of artificial turf, on a recent 64 degree afternoon, the temperature at the new Janney Envirofill field was 136 degrees, compared to 89 degrees on the grass.  And Envirofill is composed of materials resembling plastic polymer pellets (similar in appearance to tic tacs) with silica inside.  Silica is classified as a hazardous material according to OSHA regulations, and the American Academy of Pediatrics specifically recommends avoiding it on playgrounds. The manufacturers and vendors of these products claim that the silica is contained inside the plastic coating.  However, sunlight and the grinding force from playing on the field breaks down the plastic coating.   For that reason, even the product warranty admits that only 70% of the silica will remain encapsulated.  The other 30% can be very harmful as children are exposed to it in the air; here’s a screen grab from a November 2016 Patriots vs. Seahawks game, which shows how the silica sand infill is kicked up when players dive on a synthetic surface with silica sand infill.

In addition, the Envirofill pellets are coated with an antibacterial called Microban, which is a trade name for triclosan.  Triclosan is registered as a pesticide with the EPA and last year the FDA banned triclosan from soaps because manufacturers were not able to prove that it is safe for long-term use, since research shows a link to liver and inhalation toxicity and hormone disruption.  Microscopic particles of this synthetic turf infill will be inhaled by children, and visible and invisible particles come off of the field, ending up in shoes, socks, pockets, and hair.

I recently gave a guest lecture at a local college and when I asked if anyone had experience with artificial turf, two young women had stories to share.  They described playing on an artificial turf field on a sunny day, where they could actually see the heat waves rising off the field that had a strong chemical odor.

Councilwoman Cheh asked me to provide scientific evidence to back up my statements.  In addition to the links provided above regarding triclosan and silica, I want to describe the data regarding carcinogens and hormone disrupting chemicals that can cause obesity, early puberty, and attention deficits.

Scientific Evidence of Cancer and Other Systemic Harm

First, it is important to distinguish between evidence of harm and evidence of safety.  Companies that sell and install artificial turf often claim that there is “no evidence that children are harmed” or “no evidence that the fields cause cancer.”  That is often misunderstood as meaning that the products are safe or are proven to not cause harm. Neither is true.

It took decades to prove that smoking can cause cancer, a fact that everyone now agrees is true.  As each type of artificial turf is replaced by a new type of artificial turf, it will be equally difficult to prove that these different types of fields cause specific children to develop cancer, obesity, early puberty, or ADD.  For that reason, we need to focus on what is known about the materials the fields are made of and what the implications are for children’s health.

Synthetic rubber and plastic are made with different types of endocrine (hormone) disrupting chemicals as well as carcinogens.  There is very good evidence regarding these chemicals in tire crumb, based on studies done at Yale and by the California Office of Environmental Health Hazard Assessment (OEHHA).  The latter conducted three laboratory studies to investigate the potential health risks to children from playground surfaces made from recycled tires. One study evaluated the level of chemicals released and the other two studies looked at the risk of injury from falls.

The OEHHA studies showed that the children would be exposed to five chemicals, including four PAHs, one of which, chrysene,” was high enough to possibly increase the chances of a child developing cancer.[1]

Out of the 32 playgrounds studied, only 10 met that state’s standard for “head impact safety” to reduce brain injury and other serious harm in children who fall while playing. All five surfaces made of wood chips met the safety standard.[1]

A 2015 report by Yale scientists detected 96 chemicals in samples from 5 different artificial turf companies, including unused bags of tire crumb. Unfortunately, the health risks of most of these chemicals had never been studied.  However, 20% of the chemicals that had been tested are classified as probable carcinogens and 40% are irritants that can cause asthma or other breathing problems, or can irritate skin or eyes. [2]

Less is known about the materials that are used in PIP and other rubber products; some are recycled tire materials and some are “virgin rubber” but all are made from synthetic rubber, which is a petroleum based product.  This week I visited a playground at Chevy Chase Recreation Center.  Although the playground seems to be a relatively new solid rubber surface, there are several areas that are already broken, with dark crumb rubber and other very small colorful particles clearly showing. Some of the particles look like they could be from plants, but you can’t crush or tear them as you can with plant material.  Children can pick up those particles intentionally or unintentionally; little children are likely to eat it or get it in their mouths, shoes, or clothes, and children of any age will certainly get it on their skin.  As noted above, the evidence is clear that these rubber particles are dangerous.

Rather than provide a lengthy description of all the studies showing the impact of hormone-disrupting chemicals (also called endocrine disrupting chemicals or EDCs), I will assume you know that the evidence is clear about those chemicals being in rubber and plastic and causing health problems.  Scientists at the NIH environmental institute, which is called the National Institute of Environmental Health Sciences, have concluded that unlike most other chemicals,  hormone-disrupting chemicals can be dangerous at very low levels as well as at higher levels, and the exposures can be even more dangerous when they combine with other exposures in our environment.  That is why the Consumer Product Safety Commission has banned numerous endocrine disrupting chemicals from toys and products used by children ages 3 and younger.  Like playgrounds and artificial turf fields, these products were sold in the U.S. for many years prior to the ban, because the companies were not required to prove that the products were safe.

Instead of focusing on those studies, here is just one recent scientific study on the health risks of synthetic rubber.  A report warning about possible harm to people who are exposed to rubber and other hormone disrupting chemicals at work explains that these chemicals “can mimic or block hormones and disrupt the body’s normal function, resulting in the potential for numerous health effects…. Similar to hormones, EDC can function at very low doses in a tissue-specific manner and may exert non-traditional dose–response because of the complicated dynamics of hormone receptor occupancy and saturation.”[3]

That article lists numerous EDCs found in rubber products and warns that “studies are beginning to demonstrate the contribution of skin exposure to the development of respiratory sensitization and altered pulmonary function. Not only does skin exposure have the potential to contribute to total body burden of a chemical but also the skin is a highly biologically active organ capable of chemical metabolism and the initiation of a cascade of immunological events, potentially leading to adverse outcomes in other organ systems.”

Dangers of Hard Fields and Playgrounds

I want to briefly mention safety issues pertaining to Gmax scores.  As you know, a Gmax score over 200 is considered extremely dangerous and is considered by industry to pose a death risk.  The synthetic turf industry and ASTM suggest that scores should be below 165 to ensure safety comparable to a grass field.  At the roundtable it was mentioned that grass fields can also get extremely hard, which is true.  However, the hardness of natural grass fields is substantially  influenced by rain and other weather; if the field gets hard, rain or watering will make it safe again.  In contrast, once an artificial turf field has a Gmax score above 165, it needs to be replaced because while the scores can vary somewhat due to weather, the scores will inevitably get higher because the turf will get harder.  Moreover, averaging Gmax scores for a field is an inappropriate way to determine safety.  If a child (or adult) falls, it can be at the hardest part of the field, which is why that is the way safety is determined.

Conclusions

I have appreciated the opportunity to meet with several Councilmembers’ staff and I commend the Council for banning crumb rubber during FY 2018.  Unfortunately, however, Envirofill, “poured in place” rubber (PIP), EPDM, and all the other synthetic materials currently on the market all have petroleum based materials and therefore share some of the same health risks.  While the companies that sell these products claim they are safe and meet federal safety standards, there are currently no federal safety tests required to prove that these products are safe.  In many cases, the materials used are not public, making independent research difficult to conduct. None of these products are proven to be as safe as natural grass in well-constructed fields such as the Maryland Soccerplex. Although a well-respected grass expert offered a free consultation on how to install well-engineered grass designed to withstand rain and play, DGS did not respond to his offer.

I have also attached an annotated bibliography of numerous relevant scientific articles on artificial turf that will help you see that there is growing evidence of the harm of these synthetic materials on fields and playgrounds.  This is just a sample of studies, and there are many more, so let me know if you’d like additional information.

I am one of many parents and scientists in D.C. that are very concerned about the impact of these artificial fields and playgrounds on our children.  It is clear that city officials have assumed these products are safe because the salespeople told them they were safe.  Unfortunately, there is clear scientific evidence that these materials are potentially harmful, and the only question is how harmful are they and how much exposure is likely to be harmful?  Our children deserve better.

Sincerely,

Diana Zuckerman, PhD

NCHR Comments on the USPSTF’s Draft Recommendation Statement, Evidence Review, and Modeling Report on Cervical Cancer Screening

National Center for Health Research: October 9, 2017

Thank you for the opportunity to express our views on the U.S. Preventive Services Task Force (USPSTF) draft recommendation statement, evidence review, and modeling report for cervical cancer screening. The National Center for Health Research is a nonprofit think tank that conducts, analyzes, and scrutinizes research, policies, and programs on a range of issues related to health and safety. We do not accept funding from companies that make products that are the subject of our work.

We agree that this is the right time for the U.S. Preventive Services Task Force to re-evaluate its cervical cancer screening recommendations, due to new research studies and decision modeling analysis. In 2012, the USPSTF recommended starting screening at age 21 and stopping at age 65. Women could get a Pap every 3 years, or starting at age 30, women could get both a Pap and HPV test (co-test) every 5 years. Based on the USPSTF’s review, we agree with maintaining most of the 2012 recommendations, but have significant concerns about changes USPSTF has proposed.

We are very concerned about the proposed grade “A” recommendation to exclusively screen women with the HPV test every 5 years starting at age 30. As the Task Force recognized, clinical trial evidence to support primary HPV screening as a preferred screening strategy is inadequate. There is also a lack of well-designed and implemented clinical trials comparing co-testing and primary HPV screening. The pivotal ATHENA trial, the U.S. prospective study supporting the efficacy of primary HPV screening, had significant shortcomings and does not provide clear and substantial evidence that primary HPV testing reduces cancer incidence or mortality. The Task Force appropriately classified this study as “poor quality” and excluded it from the draft evidence review. However, some medical societies are still quoting it.

Due to lack of available evidence, the Task Force relied heavily on mathematical models to arrive at the grade “A” recommendation. While mathematical models that incorporate real world data help to support available evidence, they are hypothetical, and conclusions must still be weighed against evidence from clinical trials and observational studies. This definitely is well below the standard of an “A” recommendation; in fact, we believe screening based exclusively on HPV tests should not be recommended.

Based on the USPSTF’s decision modeling analysis, primary HPV testing potentially confers a slightly higher mortality benefit (approximately 10 life-years per 1000 women) compared to cytology alone, but it requires significantly more colposcopies to be done for each possible cancer averted (766 vs. 39). Moreover, the models demonstrate that primary HPV testing and co-testing prevent approximately the same amount of deaths, but co-testing would require more total tests (19,806 vs. 12,151). However, models are necessarily based on assumptions that are not necessarily accurate.  The conclusions from these models are not based on research conducted on actual patients.

In addition, while the USPSTF depended on the draft modeling report to conclude that primary HPV screening may provide more benefits than harms, other recent modeling analyses by Felix et al., concluded that screening by co-testing may be superior to screening by HPV test alone. Therefore, the totality of the evidence does not support eliminating co-testing as an acceptable strategy.

We therefore conclude that the Task Force’s grade “A” recommendation assigned to primary HPV screening is inappropriate, because it is primarily based on modeling analysis and not clinical trials or real-world data. This grade “A” would certainly mislead physicians and women to believe that there is incontrovertible evidence to support an HPV testing-only screening strategy rather than co-testing or Pap smear only testing. Since the recommendation is that women can select a Pap smear every 3 years or the HPV test every 5 years, many women will likely choose the less frequent screening option, not realizing that they will be at increased risk of needing additional, more invasive testing with the HPV test only screening.

The seven cited randomized clinical trials are difficult to interpret. First, the studies cannot be assumed to be representative of women in the U.S. since they were conducted primarily in European countries with national screening programs and more standardized triage strategies. Second, the studies were extremely heterogeneous in terms of test technology, screening intervals, and follow-up protocols. Third, the study results were mixed. For instance, the NTCC phase II trial found that hrHPV test alone had a higher CIN3 detection rate only in the first screening round, and actually had a lower rate of detection in the second round. The Task Force’s review contends that the “cumulative rate was still double.” However, it is possible  that detection rates of CIN3 declined in the second screening round because the lesions regressed due to HPV clearance.  Thus, perhaps the colposcopies triggered by HPV positivity in the first screening round were unnecessary. Bottom line: these data are inconclusive. Last, the studies included surrogate endpoints for cancer incidence and mortality, such as CIN2 or CIN3 detection. These endpoints are likely not the most meaningful outcomes for women, since CIN2/3 lesions do not always progress to cervical cancer and sometimes regress instead.  There are several other determinants of disease trajectory that may differ among women in different countries.

While we understand why the USPSTF advises women to “discuss with their provider which testing strategy is best for them” it is obvious that this advice will not necessarily provide excellent guidance for the average patient.  Many providers will not realize that population-based studies and well-conducted clinical trials do not substantially support primary HPV as a preferred testing strategy. Instead, providers are likely to depend on the USPSTF recommendation or those of medical societies, rather than careful scrutiny of the data.  Furthermore, the triage strategy for a positive HPV test is not standardized; it varies from cytology test, HPV genotype test, or direct colposcopy. Such a decision would depend on organized follow-up and would necessitate an informed discussion, which may not be possible in a single office visit. As suggested in the ARTISTIC subsample, a positive HPV test is likely to cause anxiety, and many patients will undergo colposcopy they would not have been needed had they been screened with a Pap smear instead.

In conclusion, we agree with maintaining much of the 2012 recommendations, but we strongly disagree with the proposed “A” rating for HPV testing alone, and urge that the USPSTF reconsider the shortcomings of the evidence and revise their recommendation to give preference to co-testing and Pap smears alone, rather than stand-alone HPV testing.

Thank you for the opportunity to comment on this most important issue which will have an impact on the lives of many adult women on a national level.

NCHR Statement on Right To Try Legislation before the House Energy and Commerce Subcommittee on Health

Diana Zuckerman, PhD, National Center for Health Research: October 3, 2017

Chairman Burgess, Ranking Member Pallone, and distinguished Subcommittee Members:  Thank you for the opportunity to submit hearing testimony for the record.  The National Center for Health Research is a non-profit organization which analyzes medical and scientific data and produces original health-related research to inform patients, the general public, and policymakers.  We advocate for patients and consumers to have access to safe, effective, and affordable drugs and medical devices.  We accept no funding from the pharmaceutical or medical device industries.

We all agree that terminally ill patients should receive the best medical treatment as quickly as possible.  Some terminally ill patients are willing to take big risks to have a chance to live longer.  Unfortunately, many of us know desperate patients whose efforts to “try anything” made their remaining days miserable and left their families even more devastated.  What can and should Congress do to make sure that desperate patients won’t be exploited, or suffer even more painful deaths as a result of legislation?  That is the key question before you today.

It is essential that all Members of Congress understand what the various Right to Try bills would do.  A key issue is to understand what it means to give access to any experimental treatment that has been in at least one clinical trial. The earliest clinical trials (known as Phase I) often don’t include even one patient.  Instead Phase I trials can include “healthy volunteers” that are much less likely to be harmed by an experimental drug or device than a terminally ill patient would.

In addition, these first (Phase I) clinical trials study very small numbers of people, and do not study whether or not a product works.  They are designed to determine the immediate risks on just a few healthy volunteers or patients.  Since so few people are studied, even if a treatment is immediately and painfully fatal to 10% of patients, for example, these first clinical trials probably would not be able to provide that crucial information.

The Right to Try bill introduced by Representatives Griffith and Brat do not even require that a first clinical trial be completed – it can have just started.  In other words, there is no way that a patient could be warned about any terrible risks of those treatments.

The Johnson Right to Try bill (S 204) requires that a Phase I clinical trial be completed.  That is an improvement over the Griffith and Brat bill, but it is important to know that 85% of drugs that successfully complete Phase I clinical trials are later found to be unsafe or ineffective and are therefore never approved by the FDA.  So neither version would help most patients.

In contrast, the FDA’s current expanded Access Program requires at least some evidence that an experimental treatment might possibly be helpful.  That’s not a very restrictive safeguard, but it is helps protect many patients. The FDA routinely utilizes what the agency terms “compassionate waivers” for very ill patients when doctors request them, and FDA grants such requests 99% of the time.

Another important issue for Congress to consider is whether these bills would exploit patients financially. The experimental drugs provided through the current FDA Expanded Access program are provided for free most of the time, or “at cost.”  The same is true for clinical trials.  The Johnson bill also protects patients from financial exploitation by limiting what experimental treatments can cost.  The Griffith and Brat bill allows companies to charge whatever they want to dying patients desperate for access to any experimental drug or device – even one that has absolutely no evidence that it is either safe or effective.  That means that desperate patients could be required to pay exorbitant fees for the “Right to Try” to be treated like guinea pigs.  Many families would feel tremendous guilt if they could not afford to do so.

FDA’s compassionate use program could be improved, and improvements are already underway thanks to the Navigator program that the FDA has recently initiated with the Reagan Udall Foundation.  Other access issues are inherent in the situation where patients want drugs that are not yet being manufactured in large numbers or when the companies are reluctant to provide drugs that they fear will be harmful to patients who are too ill to benefit.  The GAO’s July 2017 report was generally supportive, with a few recommendations for improvement. And, GAO pointed out that most experimental drugs distributed under Expanded Access eventually obtain FDA approval.  In other words, the program is doing what was intended – giving patients earlier (usually free) access to experimental drugs that will eventually be proven safe and effective.

In addition to harming individual patients, making unsafe treatments available for sale harms our entire drug development enterprise, by eliminating the incentive for patients to participate in clinical trials that would help millions of patients in the future.  If HR 1020 was to become law, then it is likely that the richest patients will buy access to experimental treatments and only the middle-class and low-income patients will participate in clinical trials.  Reputable companies would continue to study new drugs and devices in clinical trials, but progress would be slowed because of difficulty attracting enough patients to participate in clinical trials.  Meanwhile, scam artists and fly-by-night companies would be motivated to make as much money as possible on dangerous or worthless experimental drugs for as long as they are available, and HR 1020 and would make it impossible to gather information about how dangerous their products are.

Such problems have long been documented regarding unproven treatments sold at outrageously high prices in Mexico and elsewhere, where some patients have been irreparably harmed or killed because they sought unproven treatments that were marketed dishonestly.  Indeed, tragedies arising from the “right to try” unregulated medical sales of the 19th Century and early 20th Century were the reason FDA was created, to protect patients and consumers.

To improve Right to Try legislation, Congress should:

  1. Ensure that experimental treatments cannot be sold at a profit by companies or medical professionals;
  2. Ensure that all experimental treatments have been proven safe in completed Phase I or Phase II trials conducted on a reasonable number of patients (not healthy volunteers);
  3. All experimental drugs and devices available through RTT should be studied as part of FDA’s regulatory process;
  4. Information about harmful side effects and adverse events should be required to be reported to the FDA by the physicians.

We strongly urge this Committee to reject the Right To Try legislation that is currently under consideration, because it would undermine the successful FDA compassionate waiver program already in place to enable patients to have access to experimental drugs for free or at cost.
