CAMBRIDGE, Mass., May 7, 2026 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today outlined pipeline progress, reiterated key anticipated milestones, and reported first quarter 2026 financial results.

"The forward momentum continues at Nuvalent, with both of our parallel-lead programs advancing toward key US regulatory milestones and the opportunity to bring our first new medicine to patients this year," said James Porter, Ph.D., Chief Executive Officer of Nuvalent. "We recently submitted our NDA for neladalkib in TKI pre-treated ALK-positive NSCLC and are continuing to build our commercial infrastructure in preparation for a potential US launch of zidesamtinib in TKI pre-treated ROS1-positive NSCLC, if approved."

Dr. Porter continued, "Beyond these initial opportunities, we remain focused on progressing our label expansion strategies for ROS1- and ALK-positive NSCLC, as well as our earlier-stage pipeline, with the goal of driving meaningful, long-term impact in NSCLC and beyond. Through these efforts, we believe we are well positioned to realize our vision of becoming a sustainable biotechnology company capable of designing, developing and delivering precisely targeted therapies for patients with cancer."

Recent Pipeline Achievements and Anticipated Milestones

ROS1 Program

• The New Drug Application (NDA) for zidesamtinib, an investigational ROS1-selective inhibitor, is under review by the U.S. Food and Drug Administration (FDA) for the treatment of adult patients with locally advanced or metastatic ROS1-positive non-small cell lung cancer (NSCLC) who received at least 1 prior ROS1 tyrosine kinase inhibitor (TKI) with a Prescription Drug User Fee Act (PDUFA) target action date of September 18, 2026. Nuvalent continues to advance commercial preparations ahead of an anticipated U.S. commercial launch of zidesamtinib in 2026, pending FDA review.
• Nuvalent plans to submit data to the FDA to support a potential label expansion of zidesamtinib in TKI-naïve patients with advanced ROS1-positive NSCLC in the second half of 2026.
• Nuvalent presented new clinical and preclinical data for zidesamtinib during poster sessions at the American Association for Cancer Research (AACR) Annual Meeting 2026, including:
  • Clinical data from a subgroup of patients with advanced ROS1-positive NSCLC in the ARROS-1 clinical trial who had been previously treated with the dual TRK/ROS1 TKIs repotrectinib and/or taletrectinib. Treatment with zidesamtinib resulted in clinically meaningful activity in this heavily pre-treated subgroup, including activity in tumors with the ROS1 G2032R resistance mutation and intracranial complete responses for patients with CNS disease. These results indicate that ROS1-positive NSCLC tumors may remain ROS1-dependent beyond treatment with repotrectinib or taletrectinib.
  • Preclinical analyses supporting the potential for differentiation of the brain penetrance and intracranial ROS1 G2032R antitumor activity of zidesamtinib compared to the dual TRK/ROS1 inhibitors repotrectinib and taletrectinib. Among these three ROS1 TKIs, zidesamtinib demonstrated the highest in vitro measures of brain penetrance, most sustained intracranial efficacy in a mouse ROS1 G2032R brain tumor model, and efficacy after progressive disease on earlier-line taletrectinib treatment in a mouse ROS1 G2032R brain tumor model. Data demonstrating that switching from repotrectinib to zidesamtinib resulted in more sustained tumor suppression in the same preclinical model have been previously reported.¹
• The company also plans to present preliminary data from the ongoing ARROS-1 Phase 1/2 clinical trial of zidesamtinib in patients with advanced ROS1-positive solid tumors outside of non-small cell lung cancer (NSCLC) during a poster session at the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting from May 29 – June 2, 2026, in Chicago.

ALK Program

• Nuvalent submitted an NDA for neladalkib, an investigational ALK-selective inhibitor, in TKI pre-treated advanced ALK-positive NSCLC to the FDA. The application is based on data in TKI pre-treated patients with advanced ALK-positive NSCLC treated with neladalkib in the global, registration-directed ALKOVE-1 Phase 1/2 clinical trial. In this population, neladalkib demonstrated encouraging overall activity, including intracranial responses, the ability to address key drivers of disease progression, and a generally well-tolerated safety profile consistent with its ALK-selective, TRK-sparing design. The company plans to present pivotal data for neladalkib in TKI pre-treated patients with advanced ALK-positive NSCLC from the ALKOVE-1 study, in addition to preliminary data for TKI-naïve patients, during an oral presentation at the 2026 ASCO Annual Meeting.
• Enrollment is ongoing in ALKAZAR, the company's global Phase 3 randomized, controlled trial designed to evaluate neladalkib for the treatment of patients with TKI-naïve ALK-positive NSCLC. Patients are randomized 1:1 to receive neladalkib or alectinib, a front-line standard of care, reflecting input from collaborating physician-scientists and alignment with global regulatory agencies. The company expects to continue to progress the ALKAZAR trial throughout 2026.

HER2 Program

• Enrollment is ongoing in the HEROEX-1 Phase 1a/1b clinical trial 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. The company expects to continue to progress the HEROEX-1 trial throughout 2026.

Discovery Research Programs

• Nuvalent continues to make progress across its discovery research programs and expects to disclose a new development candidate by year-end 2026.
