Nuvalent, Inc. announced the presentation of new preclinical data supporting the intracranial activity NVL-655. NVL-655 is a brain-penetrant, ALK-selective tyrosine kinase inhibitor (TKI) designed to maintain activity against ALK and ALK mutations that confer resistance to currently approved therapies, and to avoid neurological adverse events and dose-limiting toxicities associated with TRK inhibition. NVL-655 has previously demonstrated preclinical efficacy in a cell line model of intracranial disease, as well as broad preclinical activity across diverse ALK resistance mutations and tumor types while maintaining strong selectivity for ALK over TRKB.

NVL-655 is currently being investigated in the ALKOVE-1 study (NCT05384626), a first-in-human Phase 1/2 clinical trial for patients with advanced ALK-positive NSCLC and other solid tumors.
