Nuvalent to Present Trial in Progress Posters for the ALKAZAR Trial of Neladalkib and HEROEX-1 Trial of NVL-330 at the 2025 American Society of Clinical Oncology Annual Meeting

CAMBRIDGE, Mass., April 23, 2025 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today announced two "Trial in Progress" poster presentations for its novel ALK-selective inhibitor, neladalkib, and novel HER2-selective inhibitor, NVL-330, at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting from May 30 – June 5, 2025, in Chicago. Posters will be archived on the Nuvalent website at www.nuvalent.com.

The first "Trial in Progress" poster will include background and study design for ALKAZAR (NCT06765109), a global, randomized, controlled Phase 3 trial designed to evaluate neladalkib versus the current standard of care for the treatment of patients with TKI-naïve ALK-positive non-small cell lung cancer (NSCLC). Patients will be randomized 1:1 to receive neladalkib monotherapy or ALECENSA® (alectinib) monotherapy. The company plans to initiate the ALKAZAR trial in the first half of 2025.

The second poster will include background and study design for the ongoing HEROEX-1 Phase 1a/1b clinical trial (NCT06521554) evaluating the overall safety and tolerability of NVL-330 for pre-treated patients with HER2-altered NSCLC. Additional objectives include determination of the recommended Phase 2 dose, characterization of NVL-330's pharmacokinetic profile, and preliminary evaluation of anti-tumor activity.

Details of the poster presentations are as follows:

About Neladalkib
Neladalkib is a novel brain-penetrant ALK-selective inhibitor created with the aim to overcome limitations observed with currently available ALK inhibitors. Neladalkib is designed to remain active in tumors that have developed resistance to first-, second-, and third-generation ALK inhibitors, including tumors with single or compound treatment-emergent ALK mutations such as G1202R. In addition, neladalkib is designed for central nervous system (CNS) penetrance to improve treatment options for patients with brain metastases, and to avoid inhibition of the structurally related tropomyosin receptor kinase (TRK) family. Together, these characteristics have the potential to avoid TRK-related CNS adverse events seen with dual TRK/ALK inhibitors and to drive deep, durable responses for patients across all lines of therapy. Neladalkib has received breakthrough therapy designation for the treatment of patients with locally advanced or metastatic ALK-positive non-small cell lung cancer (NSCLC) who have been previously treated with 2 or more ALK tyrosine kinase inhibitors and orphan drug designation for ALK-positive NSCLC.

About NVL-330
NVL-330 is a novel brain-penetrant HER2-selective tyrosine kinase inhibitor designed to address the combined medical need of treating HER2-mutant tumors, including those with HER2 exon 20 insertion mutations, avoiding treatment related adverse events due to off-target inhibition of wild-type EGFR, and treating brain metastases.
