Nuvalent, Inc., a clinical stage biopharmaceutical company, engages in the development of therapies for patients with cancer.

Its lead product candidates are NVL-520, a brain-penetrant ROS1-selective inhibitor to inhibit ROS1 fusions that express the normal ROS1 kinase domain without any drug-resistant mutations and remain active in the presence of mutations conferring resistance to approved and investigational ROS1 inhibitors, which is under Phase I development; NVL-655, a brain-penetrant ALK-selective inhibitor, to address the clinical challenges of emergent treatment resistance, central nervous system-related adverse events, and brain metastases that might limit the use of first-, second-, and third-generation ALK inhibitors that is under Phase ½ clinical trial; and NVL-330, a brain-penetrant human epidermal growth factor receptor 2 (HER2)-selective inhibitor designed to treat tumors driven by HER2ex20, brain metastases, and avoiding treatment-limiting adverse events including due to off-target inhibition of wild-type EGFR, which is ongoing IND-enabling studies.

The company was incorporated in 2017 and is headquartered in Cambridge, Massachusetts.
