GSK completes acquisition of Nuvalent, Inc.
GSK plc (LSE/NYSE: GSK) today announced completion of its acquisition of Nuvalent, Inc.[1], a Boston-based clinical-stage biopharmaceutical company focused on creating precisely targeted oncology therapies.
The acquisition adds three lung cancer assets to GSK's oncology portfolio. Zidesamtinib (NVL-520) and neladalkib (NVL-655) are considered potential best-in-class assets, based on clinical data, and are under FDA review for ROS1-positive and ALK-altered non-small cell lung cancer (NSCLC) with target decision dates later this year. Both have received FDA Breakthrough Therapy and Orphan Drug Designations. If approved, they are expected to launch in 2026 with multi-blockbuster potential. The acquisition also includes NVL-330 in phase I development for HER2-altered NSCLC.
Luke Miels, Chief Executive Officer, GSK, said: "Today's deal completion accelerates our entry into lung cancer with zidesamtinib and neladalkib and a platform for rapid expansion with Ris-Rez, our B7-H3 targeted ADC in phase III development. There is a clear need for these medicines in defined patient populations, consistent with our approach of acquiring validated assets that aim to improve standard of care."
Financial considerations
Under the terms of the agreement, GSK completed a tender offer to acquire all of Nuvalent's outstanding shares. The aggregate equity value of the transaction is approximately $10.6 billion (£8.0 billion). Net of cash acquired, GSK's aggregate investment is approximately $9.4 billion (£7.1 billion).
About NSCLC
NSCLC is the most common form of lung cancer and is often characterised by specific genetic alterations, such as those in ALK, ROS1, or HER2. It can often metastasise (i.e. spread) to the central nervous system. It primarily affects working-age individuals. Current treatments are associated with mutation resistance and side effects, including metabolic and neurologic events, that can adversely impact patients' quality of life.
About Nuvalent
Nuvalent (NASDAQ: NUVL) is a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for patients with cancer, designed to overcome the limitations of existing therapies for clinically proven kinase targets. Leveraging deep expertise in chemistry and structure-based drug design, Nuvalent develops innovative small molecules that have the potential to overcome resistance, minimize adverse events, address brain metastases, and drive more durable responses. Nuvalent is advancing a robust pipeline with investigational candidates for ROS1-positive, ALK-positive, and HER2-altered non-small cell lung cancer, and multiple discovery stage research programs.
