Nuvalent, Inc., a clinical stage biopharmaceutical company, develops 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; and 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 I/II clinical trial.

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