The changing face of oncology development – is cancer still ‘different’? A US perspective


Oncology development has traditionally been thought of as ‘different’; that the rules that applied to other therapy areas were not necessarily applicable to the development of treatments for cancer patients, who until relatively recently, had exceedingly limited treatment options. Dose finding was based on the paradigm adopted for cytotoxics and was focused on identifying the maximum tolerated dose, and initial accelerated or conditional approvals were sought based on a small number of patients and surrogate endpoints often in single arm trials. However, cancer mortality rates dropped by 33% between 1991 and 2020 driven by earlier detection, reductions in smoking rates and the availability of novel therapies (American Cancer Society, 2023).
