Uncharted Territory: The Lingering Uncertainty of Accelerated Cancer Drug Approvals

The U.S. Food and Drug Administration’s accelerated approval program is like the express lane for promising drugs, meant to get them into the hands of patients who need them most. However, a recent study has thrown some shade on the effectiveness of this program, revealing that most cancer drugs that receive accelerated approval fail to show tangible benefits within five years. Dr. Ezekiel Emanuel, a cancer specialist and bioethicist at the University of Pennsylvania, emphasized the importance of having a clear verdict on the efficacy of these drugs within a reasonable timeframe after accelerated approval.

In today’s landscape, a whopping 85% of accelerated approvals are granted to cancer drugs. This avenue allows the FDA to greenlight drugs that exhibit early promise in treating severe or life-threatening diseases. In return, pharmaceutical companies are required to conduct thorough testing and provide more substantial evidence before achieving full approval. The responsibility of pulling underperforming drugs lies with either the FDA or the drugmakers, with the FDA sometimes settling for less conclusive evidence for full approval.

Between 2013 and 2017, a total of 46 cancer drugs were granted accelerated approval, as revealed by the recent study. Dr. Edward Cliff from Harvard Medical School, one of the study’s authors, expressed concerns about the level of comprehension among cancer patients regarding drugs with accelerated approval. For patients with rare or advanced cancers, drugs that receive accelerated approval may be their only beacon of hope, pointed out Dr. Jennifer Litton from MD Anderson Cancer Center in Houston.

In response to the study’s findings, Congress has taken steps to revamp the accelerated approval program, empowering the FDA and expediting the process for retracting approvals when drug companies fall short on their commitments. The updated regulations grant the FDA increased authority to swiftly withdraw approval for a drug that was initially greenlit under accelerated approval, as articulated by FDA spokesperson Cherie Duvall-Jones in an email.

While the accelerated approval program continues to be a vital pathway for expediting access to potentially life-saving drugs, the recent study underscores the pressing need for more rigorous monitoring and evaluation of these drugs post-approval. In the ever-evolving realm of healthcare, striking a delicate balance between speedy access and thorough scrutiny remains paramount in ensuring the safety and efficacy of medications granted accelerated approval.
