The emergence of immunotherapy has caused a wave of co-development of anticancer drugs globally, and some unreasonable or unwarranted combination of anticancer drugs was observed. Combining regulatory guidance with case studies, this study aims to clarify key generally applicable principles in the co-development of combination therapy, when it’s appropriate to start a confirmatory trial, possible scenarios and main determinants of the most efficient confirmatory trial design. Biological rationale for the combination, adequate safety profile of each individual drug and the combination, added efficacy of the combination and attribution of each individual drug, are three golden basic principles for anticancer combination therapy. Before initiation of a confirmatory trial, a powered factorial study supporting the superiority of the combination over individual drug and standard-of-care is recommended. The appropriate design of pivotal study is generally a class-by-class determination, mainly based on whether there is a similar drug approved for the more active drug, what has been previously demonstrated about the effects of the combination and the individual drugs, the feasibility of monotherapy and standard-of-care alone treatment arms, the best practice and other factors.
