CHICAGO – An integrated analysis of three trials has shown that larotrectinib, an oral selective inhibitor of tropomyosin receptor kinase (TRK), has durable efficacy across diverse adult and pediatric cancers harboring TRK fusions, netting an impressive 76% overall response rate.
Lead study author David Hyman, MD, chief of early drug development at Memorial Sloan Kettering Cancer Center in New York, discussed highlights of the analysis, larotrectinib’s regulatory status, and implications for TRK fusion testing in clinical care at the annual meeting of the American Society of Clinical Oncology.
Dr. Hyman disclosed that he has a consulting or advisory role with Atara Biotherapeutics, Chugai Pharma, and CytomX Therapeutics, and that he receives research funding from AstraZeneca and Puma Biotechnology. The study was funded by Loxo Oncology.
