• Completed rolling NDA submission for zidesamtinib in TKI pre-treated advanced ROS1-positive NSCLC
• On track to report topline pivotal data for neladalkib in TKI pre-treated advanced ALK-positive NSCLC by year-end 2025
• Strong financial position with operating runway anticipated into 2028

CAMBRIDGE, Mass., Oct. 30, 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 outlined pipeline progress, reiterated key anticipated milestones, and reported third quarter 2025 financial results.

"The third quarter of 2025 marked the achievement of a significant milestone with the completion of our NDA submission for zidesamtinib in TKI pre-treated advanced ROS1-positive NSCLC. We look forward to working closely with the FDA throughout the review process, as well as continuing to engage with the agency on potential opportunities for line-agnostic expansion," said Darlene Noci, A.L.M., Chief Development Officer of Nuvalent. "We remain on track to share topline pivotal data this quarter from our ALKOVE-1 trial of neladalkib in TKI pre-treated advanced ALK-positive NSCLC, and continue to progress ALKAZAR, our global Phase 3 randomized, controlled trial of neladalkib for TKI-naïve patients with advanced ALK-positive NSCLC."

"Our commercial preparedness activities are well underway as we carry forward the momentum from these exciting development milestones and continue our efforts to transition toward becoming a fully integrated commercial-stage biopharmaceutical company," said Alex Balcom, Chief Financial Officer of Nuvalent. "Combined with a strong financial position with cash runway anticipated into 2028, we believe we are well positioned to achieve our goal of delivering a new and potential best-in-class option for all patients with ROS1 or ALK-positive NSCLC."

"We are also pleased to have recently shared the first report of preliminary clinical data demonstrating the potential for neladalkib to address medical needs for patients with ALK-positive solid tumors beyond NSCLC, and new preclinical data further demonstrating the potential for NVL-330 to offer a differentiated profile for HER2-altered NSCLC," said James Porter, Ph.D., Chief Executive Officer of Nuvalent. "With a portfolio anchored by complementary indications in biomarker-driven NSCLC and supported by a robust development and discovery pipeline, we continue to build towards our long-term vision of Nuvalent as a sustainable company capable of designing, developing and delivering precisely targeted therapies for patients with cancer."

Recent Pipeline Achievements and Anticipated Milestones

ROS1 Program

• The company has completed its rolling NDA submission for zidesamtinib in tyrosine kinase inhibitor (TKI) pre-treated patients with advanced ROS1-positive non-small cell lung cancer (NSCLC).
• Data supporting the NDA submission were presented in September as part of the Presidential Symposium at the IASLC 2025 World Conference on Lung Cancer.
• The company continues to engage with the FDA on potential opportunities for line-agnostic expansion.

ALK Program

• Evaluation of neladalkib is ongoing in the ALKOVE-1 Phase 1/2 trial for patients with advanced ALK-positive NSCLC and other solid tumors:
  • The company presented preliminary data from the ongoing ALKOVE-1 Phase 1/2 clinical trial of neladalkib in patients with advanced ALK-positive solid tumors outside of NSCLC during a poster presentation at the European Society for Medical Oncology (ESMO) Congress 2025. Neladalkib demonstrated encouraging preliminary activity across a diverse set of advanced ALK-positive solid tumors, and was generally well-tolerated with a preliminary overall safety profile consistent with its ALK-selective, TRK sparing design, and with previously reported data.
  • The company is on track to report topline pivotal data for TKI pre-treated patients with advanced ALK-positive NSCLC by year-end 2025.
• 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.

HER2 Program

• Nuvalent presented new preclinical data for its novel HER2-selective inhibitor, NVL-330, at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, further supporting its potentially differentiated brain-penetrant profile. Compared to several currently available and investigational HER2 TKIs in the same preclinical assays, NVL-330 demonstrated a favorable efflux ratio and brain partitioning, metrics that are potentially positive predictors of brain exposure in humans. In preclinical models of intracranial activity, NVL-330 induced deep intracranial regression in mice. In the same models, the approved therapies T-DXd and zongertinib did not induce intracranial regression at their clinically relevant doses. Additionally, NVL-330 induced intracranial tumor regression in mice that had progressed in the CNS on zongertinib. These data add to the preclinical characterization of NVL-330 as a brain penetrant TKI that is broadly active against HER2 oncogenic alterations and selective over wild-type EGFR, and the company believes the data support its investigation in patients with advanced HER2-altered NSCLC.
• 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 2025.

Upcoming Events

• Jefferies 2025 Global Healthcare Conference in London: Management will be participating in a fireside chat on Wednesday, November 19, 2025, at 5:00 p.m. GMT.
