FDA's Project Optimus Drives Dose Optimisation in Oncology Trials
The FDA's Project Optimus, launched in 2021, continues to influence oncology trial designs, as discussed at the AACR 2026. The initiative aims to refine dose selection in cancer treatments, moving away from the traditional maximum tolerated dose approach. Instead, it emphasizes selecting doses based on efficacy, safety, and tolerability. This shift is crucial for newer cancer therapies like targeted treatments and immunotherapies, where the effective dose may be lower than the toxicity threshold. The project encourages more structured, comparative evidence generation in early-phase trials, integrating patient-reported outcomes to better reflect patient experiences and improve treatment tolerability.
