J&J and Sientra get FDA warning letters over breast implants
(Reuters) - The U.S. Food and Drug Administration has issued warning letters to Sientra Inc and a Johnson & Johnson unit for failing to comply with the post-approval study requirements for their breast implants. The long-term safety of breast implants has been questioned over the years.
(Reuters) - The U.S. Food and Drug Administration has issued warning letters to Sientra Inc and a Johnson & Johnson unit for failing to comply with the post-approval study requirements for their breast implants.
The long-term safety of breast implants has been questioned over the years. Last month, the FDA issued a statement warning doctors about a type of lymphoma linked to breast implants after receiving reports of the disease.
The agency's letters, dated March 18, highlighted issues in the companies' post-approval studies, which included evaluating the long-term performance and safety of the implants, used for breast augmentation and reconstruction procedures.
The letter to J&J's medical aesthetics unit Mentor Worldwide LLC noted "several serious deficiencies" in the company's post-approval study for its MemoryShape breast implant approved in 2013.
Failure to enroll the required number of patients in the study and data inconsistencies, including poor patient accounting and missing race and ethnicity data, were identified as violations in the letter to Mentor.
Mentor said it was disappointed with the FDA's decision to issue a warning letter, even as the company attempted to address post-approval study requirements with the agency.
"Despite multiple attempts to discuss this with FDA, Mentor has not received feedback," Mentor spokeswoman Mindy Tinsley said in an emailed statement.
Sientra had reported a poor patient follow-up rate of 61 percent for the post-approval study of its silicone gel breast implants, which required the company to evaluate the study subjects annually for 10 years, according to the FDA letter.
The agency said failure to make good the violations may result in the withdrawal of the premarket approval granted to the products.
The FDA asked the companies to provide responses within 15 working days with details about how the noted violations will be corrected.
Last year, the U.S. Securities and Exchange Commission sued Sientra's former chief executive for fraudulently concealing problems with his company's breast and other implants while raising $61.4 million in a public stock offering.
Shares of Sientra were down 1.8 percent at $8.65, while J&J shares were flat in after market trading.

By Robin Emmott and John Irish | BRUSSELS/PARIS BRUSSELS/PARIS France and Germany will agree to a U.S. plan for NATO to take a bigger role in the fight against Islamic militants at a meeting with President Donald Trump on Thursday, but insist the move is purely symbolic, four senior European diplomats said.The decision to allow the North Atlantic Treaty Organization to join the coalition against Islamic State in Syria and Iraq follows weeks of pressure on the two allies, who are wary of NATO confronting Russia in Syria and of alienating Arab countries who see NATO as pushing a pro-Western agenda."NATO as an institution will join the coalition," said one senior diplomat involved in the discussions. "The question is whether this just a symbolic gesture to the United States
BEIJING Chinese President Xi Jinping on Wednesday called for greater efforts to make the country's navy a world class one, strong in operations on, below and above the surface, as it steps up its ability to project power far from its shores.China's navy has taken an increasingly prominent role in recent months, with a rising star admiral taking command, its first aircraft carrier sailing around self-ruled Taiwan and a new aircraft carrier launched last month.With President Donald Trump promising a US shipbuilding spree and unnerving Beijing with his unpredictable approach on hot button issues including Taiwan and the South and East China Seas, China is pushing to narrow the gap with the U.S. Navy.Inspecting navy headquarters, Xi said the navy should "aim for the top ranks in the world", the Defence Ministry said in a statement about his visit."Building a strong and modern navy is an important mark of a top ranking global military," the ministry paraphrased Xi as saying.
