Recently, the U.S. Food and Drug Administration (FDA) announced that the agency will hold a public meeting of the Oncologic Drugs Advisory Committee on April 27 to 29 to discuss six indications granted accelerated approval that have since reported results from confirmatory trials that have not verified a clinical benefit. These products are being used under accelerated approval to treat patients with breast, urothelial, gastric, and hepatocellular cancers. The discussion will encompass the following drugs and indications:
The FDA’s Oncology Center of Excellence requested this meeting as part of an industry-wide evaluation of accelerated approvals in oncology in which confirmatory trials did not confirm clinical benefit. Based on the updates provided at this meeting, the committee will have a general discussion of individual drugs, including the continued approval of the specific indication and if additional trials would be required.
Through this industry-wide evaluation, four indications were voluntarily withdrawn or voluntary withdrawal is planned in consultation with the FDA:
Since the inception of the accelerated approval program, including these four withdrawals, only 6% of accelerated approvals for oncology indications have been withdrawn.

Richard Pazdur, MD, Director of the FDA’s Oncology Center of Excellence and Acting Director of the Office of Oncologic Diseases in the FDA’s Center for Drug Evaluation and Research, commented: “We are committed to ensuring the integrity of the accelerated approval program, which is designed to bring safe and effective drugs to patients with unmet medical needs as quickly as possible. The program allows the FDA to approve a drug or biologic product intended to treat a serious or life-threatening condition based on an outcome that can be measured earlier than survival that demonstrates a meaningful advantage over available therapies. However, when confirmatory trials do not confirm clinical benefit, a reevaluation must be performed to determine if the approval should be withdrawn.”
He concluded: “This public meeting of the advisory committee creates an opportunity for external oncology experts and patients with cancer to share input and perspective with the FDA. After this advisory meeting, our staff will consider the committee’s comments and will make final decisions regarding continuing approval of each indication."The content in this post has not been reviewed by the American Society of Clinical Oncology, Inc.
