The Food and Drug Administration is under pressure from the Trump administration to approve drugs faster, but researchers at the Yale School of Medicine found that nearly a third of those approved from 2001 through 2010 had major safety issues years after the medications were made widely available to patients.
Seventy-one of the 222 drugs approved in the first decade of the millennium were withdrawn, required a "black box" warning on side effects or warranted a safety announcement about new risks, Dr. Joseph Ross, an associate professor of medicine at Yale School of Medicine, and colleagues reported in JAMA on Tuesday. The study included safety actions through Feb. 28.
"While the administration pushes for less regulation and faster approvals, those decisions have consequences," Ross says. The Yale researchers' previous studies concluded that the FDA approves drugs faster than its counterpart agency in Europe does and that the majority of pivotal trials in drug approvals involved fewer than 1,000 patients and lasted six months or less.
It took a median of 4.2 years after the drugs were approved for these safety concerns to come to light, the study found, and issues were more common among psychiatric drugs, biologic drugs, drugs that were granted "accelerated approval" and drugs that were approved near the regulatory deadline for approval.
