Nuvalent Highlights Pipeline Progress and Reports Second Quarter 2023 Financial Results

Continued execution across pipeline with clinical trials ongoing for NVL-520 and NVL-655, and advancement of NVL-330 toward clinical development

Preliminary dose-escalation data anticipated from ongoing ALKOVE-1 study of NVL-655 for patients with advanced ALK-positive NSCLC and other solid tumors at a medical meeting in the fourth quarter of 2023

$431.2 million in cash, cash equivalents and marketable securities expected to support operating runway into the second half of 2025

CAMBRIDGE, Mass., Aug. 10, 2023 /PRNewswire/ -- Nuvalent, Inc. (Nasdaq: NUVL), a clinical-stage biopharmaceutical company focused on creating precisely targeted therapies for clinically proven kinase targets in cancer, today highlighted pipeline progress and reported second quarter 2023 financial results.

"As we enter the second half of 2023, we are well positioned to continue advancing our pipeline of novel kinase inhibitors," said James Porter, Ph.D., Chief Executive Officer at Nuvalent. "The focused efforts of our team in the first half of 2023 have laid the foundation for a number of meaningful development milestones, including the planned reporting of preliminary Phase 1 data at a medical meeting in the fourth quarter of the year from the dose-escalation portion of our ALKOVE-1 Phase 1/2 trial of NVL-655. Additionally, progress continues towards the selection of a recommended Phase 2 dose and transition to Phase 2 in our ARROS-1 Phase 1/2 trial of NVL-520, and the submission of a new IND application for NVL-330 for the treatment of patients with HER2 exon 20 insertion-positive cancers. I'm incredibly proud of what this team has accomplished to date and look forward to providing further updates later on this year."

Pipeline Highlights and Key Anticipated Milestones

• Preliminary Data from ALKOVE-1 Phase 1/2 Trial of NVL-655 Anticipated at a Medical Meeting in the Fourth Quarter of 2023: NVL-655 is a brain-penetrant ALK-selective inhibitor designed with the aim to address the clinical challenges of emergent treatment resistance, central nervous system (CNS)-related adverse events, and brain metastases that may limit the use of first-, second-, and third-generation ALK inhibitors. Our ALKOVE-1 clinical trial is a first-in-human Phase 1/2, multicenter, open-label, dose-escalation and expansion study evaluating NVL-655 as an oral monotherapy in patients with advanced ALK-positive NSCLC and other solid tumors. The Phase 1 dose-escalation portion of the study is enrolling patients with previously treated ALK-positive solid tumors and will evaluate the overall safety and tolerability of NVL-655. Additional objectives include determination of the recommended Phase 2 dose (RP2D), characterization of the pharmacokinetic profile, and evaluation of preliminary anti-tumor activity. The company anticipates reporting preliminary dose-escalation data from this trial at a medical meeting in the fourth quarter of 2023.
• ARROS-1 Phase 1/2 Trial of NVL-520 Progressing Toward Selection of RP2D: NVL-520 is a novel ROS1-selective inhibitor designed with the aim to address the clinical challenges of emergent treatment resistance, CNS-related adverse events, and brain metastases that may limit the use of currently available ROS1 inhibitors. Our ARROS-1 clinical trial is a first-in-human Phase 1/2, multicenter, open-label, dose-escalation and expansion study evaluating NVL-520 as an oral monotherapy in patients with advanced ROS1-positive NSCLC and other solid tumors. Enrollment of patients with previously treated ROS1-positive solid tumors is ongoing in the Phase 1 portion of ARROS-1 and the company is advancing toward the selection of an RP2D.
• NVL-330 Continuing to Advance through IND-enabling Studies: NVL-330, is a brain-penetrant HER2-selective inhibitor designed with the aim to address the combined medical need of treating tumors driven by HER2 mutations occurring through deletions, insertions, or duplications (collectively, known as HER2 Exon 20 Insertions, or HER2ex20), treating brain metastases, and avoiding treatment-limiting adverse events including due to off-target inhibition of wild-type EGFR. NVL-330 is advancing through IND-enabling studies.

Second Quarter 2023 Financial Results

• Cash Position & Operating Runway: Cash, cash equivalents and marketable securities were $431.2 million as of June 30, 2023. Nuvalent believes the existing cash, cash equivalents and marketable securities are expected to be sufficient to fund its current operating plan into the second half of 2025.
• R&D Expenses: Research and development (R&D) expenses were $25.9 million for the second quarter of 2023.
• G&A Expenses: General and administrative (G&A) expenses were $8.1 million for the second quarter of 2023.
• Net Loss: Net loss for the second quarter of 2023 was $29.1 million, or $0.51 per share.
