Nuvalent Inc. Marks a Significant Milestone with the Initiation of the ALKAZAR Phase 3 Trial for ALK-Positive NSCLC
Concord, Massachusetts – July 21, 2025 – Nuvalent Inc., a clinical-stage biopharmaceutical company dedicated to revolutionizing treatment for patients with severe and life-threatening neurological and driveN oncologiEs, today announced the initiation of its pivotal Phase 3 randomized, controlled ALKAZAR clinical trial. This landmark trial is designed to evaluate the efficacy and safety of neladalkib, Nuvalent’s investigational brain-penetrant ROS1 and ALK inhibitor, in patients with treatment-naïve, ALK-positive non-small cell lung cancer (NSCLC).
The commencement of the ALKAZAR trial represents a crucial step forward in Nuvalent’s mission to address unmet needs in oncology. ALK-positive NSCLC is a type of lung cancer driven by genetic alterations in the anaplastic lymphoma kinase (ALK) gene, which are present in approximately 5% of NSCLC patients. While tyrosine kinase inhibitors (TKIs) have significantly improved outcomes for these patients, there remains a continuous need for more effective and durable treatment options, particularly those that can overcome resistance mechanisms and address central nervous system (CNS) metastases, a common challenge in this patient population.
Neladalkib has demonstrated promising activity in preclinical models and earlier-stage clinical studies, highlighting its potential to be a differentiated treatment for ALK-positive NSCLC. Its design as a brain-penetrant inhibitor is particularly significant, offering the potential for enhanced efficacy in treating or preventing brain metastases, which can profoundly impact patient quality of life and survival.
The ALKAZAR trial is a global, multi-center study that will enroll patients with newly diagnosed, ALK-positive advanced NSCLC who have not previously received TKI therapy. Participants will be randomized to receive either neladalkib or a standard-of-care TKI. The primary endpoint of the trial is expected to be progression-free survival (PFS). Nuvalent anticipates that the data from ALKAZAR will provide a comprehensive understanding of neladalkib’s potential to become a new standard of care for this important patient group.
“We are thrilled to announce the initiation of the ALKAZAR Phase 3 trial, a critical step in our journey to bring neladalkib to patients with ALK-positive NSCLC,” said [Name and Title of Nuvalent Executive, e.g., Rory O’Day, Chief Executive Officer of Nuvalent]. “The ALKAZAR study is designed to rigorously assess neladalkib’s potential to provide superior clinical benefit, including robust CNS activity, for patients receiving their first TKI therapy. We are deeply committed to advancing this important program and are grateful to the patients, investigators, and their families who will participate in this trial.”
Nuvalent is dedicated to a patient-centric approach in its clinical development programs, and the company looks forward to working closely with the global oncology community to execute the ALKAZAR trial efficiently and effectively. The successful completion of this Phase 3 study could pave the way for regulatory submissions and the potential availability of neladalkib to patients in need.
The company will continue to provide updates on the progress of the ALKAZAR trial as significant milestones are achieved.
