The US FDA Accelerated Approval of sotorasib required the sponsor to conduct a randomized trial that compared the safety and efficacy of the approved dose with a lower dose. These results, recently disclosed, have important implications for patients, payers, oncologists and the pharmaceutical industry.
The FDA approval of perioperative pembrolizumab, an approach that combines neoadjuvant and adjuvant therapy with this agent, for patients with early stage non-small-cell lung cancer (NSCLC) contradicts its own stated standard for combination therapies. Given the large population of patients with early stage NSCLC and the high costs of pembrolizumab, whether the adjuvant component provides incremental benefit is an important question.
Through Project Optimus, the FDA calls for radical changes in the design of early phase trials to identify the optimal doses of oncology drugs to achieve maximal efficacy with better tolerability and patient acceptability. Herein, we discuss approaches that will enable the implementation of this initiative as well as some concerns that the draft guidance has raised in the oncology community.
