Although the MYSTIC phase 3 clinical trial examining durvalumab therapy for non–small-cell lung cancer (NSCLC) did not meet its primary end points – overall survival (OS) and progression-free survival (PFS) – it did show a numerically reduced risk for death with durvalumab (Imfinzi) versus chemotherapy in patients with PD-L1 expression on ≥25% of tumor cells.
Dr. David P. Carbone, Director of the Thoracic Oncology Center at Ohio State University, comments on a study evaluating the efficacy of anti–PD1/PD-L1 monotherapy for patients with NSCLC and active brain metastases: “…the initial hope that PD‑1 inhibitors could be active on brain metastases has not been fully fulfilled, and the aggressive use of stereotactic […]
The term abscopal effect (from Latin, ab, meaning “away from,” and scopus, meaning “target”) was coined in 1953, specifically referring to effects of ionizing radiation outside the radiated tumor volume. Does the evidence show that, contrary to widely held perception in the field, the abscopal effect is exceedingly rare and is not clinically relevant when […]
Another win for Merck and Keytruda, as the FDA granted accelerated approval to pembrolizumab in combination with chemotherapy for the treatment of patients with locally recurrent unresectable or metastatic triple-negative breast cancer (TNBC) whose tumors express PD-L1 based on PFS. The FDA also approved a companion diagnostic, PD-L1 IHC 22C3 pharmDx.
