Last year. Nature Reviews Drug Discovery asked the FDA’s Tatiana Prowell (Hematology & Oncology Products Division) about the most common pitfalls confronting clinical trials in oncology. She cited the late stage evaluations of biomarkers as one of three critical issues leading to regulatory failure [1]. The primary lesson: those who want to test biomarkers need to start earlier.

Professor LJ Wei holds that rules are for lawyers, not (necessarily) clinicians. When designing modern clinical trials, the impetus is often to use “efficient and reliable procedures, to obtain clinically interpretable results with respect to risk-benefit analysis…” Yet these efficient and reliable procedures are often just conventions and rules that provide information that is incomplete or...

The above graphic is from Cyrus Mehta's slides on 'Adaptive Population Enrichment for Oncology Trials with Time to Event Endpoints.'

 

Recent advances in precision medicine have meant that therapeutic treatments can now target subsets of a population that are most likely to respond well to treatment. Identification of such subsets largely relies on the presence or absence of particular...
