Nuvalent, Inc. received FDA acceptance of its New Drug Application for zidesamtinib on January 12 2026, setting a PDUFA target action date of September 18 2026. The acceptance signals that the agency considers the submitted data sufficient for a full review and brings the company one step closer to a commercial launch in 2026.
Zidesamtinib is a brain‑penetrant, ROS1‑selective inhibitor designed to treat patients with ROS1‑positive non‑small cell lung cancer (NSCLC) who have progressed on prior tyrosine‑kinase inhibitors. Its enhanced central nervous system penetration and activity against resistance mutations such as G2032R differentiate it from earlier ROS1 agents and address a critical unmet need for patients with brain metastases.
The September 18 PDUFA date places the drug in the 2026 approval window, aligning with Nuvalent’s OnTarget 2026 operating plan. The plan calls for building commercial infrastructure, securing manufacturing capacity, and positioning zidesamtinib for a launch that could transform the company from a clinical‑stage entity into a revenue‑generating oncology player.
Nuvalent’s broader pipeline includes neladalkib for ALK‑positive NSCLC and NVL‑330 for HER2‑altered NSCLC, underscoring a diversified strategy. The company reported roughly $1.4 billion in cash and equivalents as of December 31 2025, providing runway through 2029 and supporting continued development and commercialization efforts.
On the announcement day, Nuvalent’s shares rose modestly, reflecting investor confidence in the regulatory milestone. The company’s market capitalization increased by about $65 million, and trading volume reached 2.3 times the daily average, indicating heightened interest in the company’s future prospects.
James Porter, Ph.D., CEO, said the FDA acceptance “marks a transformative moment for Nuvalent, validating our OnTarget 2026 strategy and positioning us to bring a first commercial product to patients in 2026.” He added that the company is advancing commercial readiness activities while continuing to develop its pipeline.
