Solid Tumor Trials: Maintain More Patients with irRECIST

The Journal for ImmunoTherapy of Cancer recently published ‘Comparison of tumor assessments using RECIST 1.1 and irRECIST, and association with overall survival,’ marking the first time immune-related criteria show correlation with Overall Survival as its most meaningful endpoint in the treatment of cancer patients.

The publication demonstrates the benefit to a subgroup of patients who otherwise would have foregone treatment and survival benefit when relying solely on RECIST 1.1 instead of irRECIST, as irRECIST takes the entire tumor burden including new tumor growth into consideration.

In this webinar, Dr. Oliver Bohnsack of Calyx – a leading expert on RECIST and irRECIST – discusses the implications of these findings, what it means for oncology clinical development and treatment decision-making, and why irRECIST easily can and shall replace outdated RECIST 1.1 on all solid tumor trials going forward.
