Strategic risk assessment in oncology: Utilizing single-agent activity to boost combination therapy approvals

The likelihood of approval for combination therapies is higher when combined with monotherapy drugs that have previously shown single agent activity. This finding is consistent with other research on historical approval rates and the common consensus within oncology drug development. Here we suggest that by leveraging monotherapy drug activity there can be an enhanced prioritization of anti-cancer agents repurposed for combination therapies, which would have otherwise been shelved based on their single agent failure.
