Lauren Dunn, NBC News: March 19, 2019.
Less than a week before a major hearing on breast implant safety, the FDA issued two warning letters to implant manufacturers, citing their failure to do proper safety studies.
The letters sent to Mentor and Sientra warned that certain implants could be pulled off the market if the companies didn’t fulfill the agency’s requirements, which ask that manufacturers continue safety studies even after the devices are approved.
According to the letters, Mentor failed to enroll enough people in these studies. Sientra had poor follow-up rates.
“The FDA has the authority to say you either have to study it or take off the market and the company has the incentive to do one or the other,” Diana Zuckerman, president of the National Center for Health Research, told NBC News.
Zuckerman also called the letters “surprising but encouraging,” and questioned whether the FDA would take action if the companies failed to comply with the warning letters.
“You can’t assume that just because they sent the warning letter, it’s anything more than the FDA flexing their muscles,” Zuckerman said. “If the companies don’t get scared enough to comply, the big question is whether the FDA will follow through.”
In a statement to NBC News, Mentor, said it had made “multiple attempts” to discuss study requirements for its MemoryShape breast implants with the FDA.
