CAMBRIDGE, Mass., Nov. 10, 2022 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today reported recent business and pipeline progress and third quarter 2022 financial results.

"This has been a transformational year for Nuvalent, exemplified by the totality of the data presented at EORTC-NCI-AACR (ENA) which showcased the rapid and meaningful progress our team has made towards our mission of delivering a portfolio of precisely targeted therapies for patients with cancer," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "Importantly, we reported preliminary data from the Phase 1 portion of our ARROS-1 study for NVL-520 in heavily pre-treated patients with ROS1-positive non-small cell lung cancer (NSCLC), representing the first clinical proof-of-concept data from our portfolio. We believe these data support the planned investigation of NVL-520 in the treatment-naïve setting as part of the next phase of our study and continue to support the best-in-class potential of NVL-520 for the treatment of patients with ROS1-positive NSCLC. We look forward to engaging with regulators to discuss the recommended Phase 2 dose and beginning the Phase 2 portion of the ARROS-1 trial."

Dr. Porter continued, "Furthermore, the learnings from our work on NVL-520 and the ARROS-1 trial have directly informed our parallel lead program, NVL-655, and the design of the ALKOVE-1 trial for patients with ALK-positive NSCLC, as well as our earlier-stage pipeline including our third development candidate, NVL-330. Data supporting the differentiated preclinical profiles of NVL-655 and NVL-330 were presented at ENA. Enrollment in the Phase 1 portion of the ALKOVE-1 study continues, and we look forward to updating on each of these programs in the future."

"In just a few years from the company's creation, we have brought forward three potential best-in-class molecules and delivered clinical proof-of-concept data from our first program, which is a testament to the strength of our team and our ability to execute," added Alexandra Balcom, Chief Financial Officer at Nuvalent. "This execution enabled us to complete an upsized public offering of our common stock that meaningfully extends our expected operating runway and fuels the continued advancement of our clinical-stage pipeline with NVL-520 and NVL-655, as well as our early research and development pipeline, led by NVL-330. With a founding scientific thesis that we have started to see play out in the clinic, this is an energizing time for Nuvalent and we are excited to carry this momentum forward."

Pipeline Progress

• Preliminary Dose-Escalation Data from Ongoing ARROS-1 Trial Demonstrates Proof-of-Concept for NVL-520's Potential Best-in-Class Clinical Profile: Initial data from the Phase 1 dose-escalation portion of Nuvalent's ongoing ARROS-1 Phase 1/2 clinical trial of NVL-520, its novel, brain-penetrant, ROS1-selective inhibitor, as a potential treatment for patients with advanced ROS1-positive NSCLC and other solid tumors were presented during the "New Drugs on the Horizon" plenary session at ENA 2022. Data presented showed that a favorable preliminary safety profile was observed with NVL-520 treatment with no dose-limiting toxicities, treatment-related serious adverse events, treatment-related dizziness, or adverse events leading to treatment reductions or discontinuations. Additionally, treatment with NVL-520 resulted in encouraging preliminary signs of activity observed across all dose levels in heavily pre-treated patients with ROS1-positive NSCLC, including in subgroups of patients with G2032R resistance mutation or with brain metastases.
  
  The ARROS-1 clinical trial is continuing to enroll patients in the Phase 1 portion of the study and is focused on further characterizing the safety profile of NVL-520, its pharmacokinetic profile, and determining the recommended Phase 2 dose.
  
  
• New Data in Patient-Derived Models Continues to Support Best-in-Class Preclinical Profile of Parallel Lead Candidate, NVL-655: A poster presented at ENA 2022 included new preclinical data on NVL-655, Nuvalent's brain penetrant, ALK-selective inhibitor, in additional patient derived models harboring single and compound ALK resistance mutations. Notably, NVL-655 induced regression in an in vivo model derived from a patient with ALK fusion-positive NSCLC harboring G1202R/L1196M compound mutation after disease progression on sequential crizotinib, alectinib and lorlatinib treatment. Among all inhibitors tested, NVL-655 showed the broadest preclinical activity across ALK fusion partners and resistance mutations while maintaining a wide selectivity window over TRKB.
  
  Clinical investigation of NVL-655 is ongoing and enrollment is progressing in the Phase 1 portion of the ALKOVE-1 Phase 1/2 study of NVL-655 for patients with advanced ALK-positive NSCLC and other solid tumors. The Phase 1 portion of the ALKOVE-1 trial is focused on characterizing the safety profile of NVL-655, its pharmacokinetic profile, and determining the recommended Phase 2 dose.
  
  
• Preclinical Profile of NVL-330 Demonstrates Achievement of Target Characteristics of Potency and Selectivity for HER2 Exon 20 Insertion Mutations, and Brain Penetration: Nuvalent presented preclinical data characterizing its third development candidate, NVL-330, a novel, brain-penetrant HER2-selective tyrosine kinase inhibitor targeting HER2 exon 20 insertion mutations (HER2ex20) during a poster session at ENA 2022. Preclinical data demonstrated that NVL-330 potently inhibited HER2ex20 in cell-based assays and was highly selective for HER2ex20 as opposed to the structurally related wild-type EGFR and other off-target kinases – a critical aspect of NVL-330's design given that off-target inhibition of EGFR results in dose-limiting side effects including skin rash and gastrointestinal toxicity. In addition, given its demonstrated preclinical brain penetrance and intracranial activity, NVL-330 has the potential to treat or prevent brain metastasis as a potential best-in-class molecule.

Financing Highlight

• Completed Upsized Public Offering of Common Stock Raising $264.5 Million in Gross Proceeds: On November 3, 2022, Nuvalent closed an upsized underwritten public offering of 7,895,522 shares of Class A common stock at a price to the public of $33.50 per share.
