Item 8.01. Other Events.

On October 28, 2022, Nuvalent, Inc. (the “Company”) issued a press release announcing initial data from the Phase 1 dose-escalation portion of its ongoing ARROS-1 Phase 1/2 clinical trial of NVL-520 for patients with advanced ROS1-positive non-small cell lung cancer (NSCLC) and other solid tumors. A copy of the press release is filed as Exhibit 99.1 hereto and incorporated herein by reference.

The preliminary dose-escalation data were based on an enrollment cut-off date of September 1, 2022, and a data cut-off date of September 13, 2022. Thirty-five patients were enrolled, of which 34 patients had confirmed ROS1-positive NSCLC and 51% (18/35) had a history of central nervous system (CNS) metastases.

The patient population was heavily pre-treated:

• 77% (27/35) had received three or more prior lines of anti-cancer therapy;

• 71% (25/35) had two or more prior ROS1 tyrosine kinase inhibitors (TKIs) and one or more lines of chemotherapy; and

• 80% (28/35) had received a ROS1 TKI other than crizotinib or entrectinib, including lorlatinib (57%, 20/35) or repotrectinib (34%, 12/35).

Patients were treated with NVL-520 across five evaluated dose levels ranging from 25 mg once daily (QD) to 125 mg QD, and preliminary safety and pharmacokinetics of NVL-520 were evaluated as of the data cut-off date. Key findings as of the data cut-off date include:

• NVL-520 demonstrated exposure above all target efficacy thresholds (ROS1 wild type and ROS1 G2032R in both the periphery and in the CNS).

• Favorable pharmacokinetics and low intra-cohort patient pharmacokinetic variability were observed, with exposure increasing with increasing dose level and half-life supportive of once daily dosing.

• No dose-limiting toxicities, treatment-related serious adverse events, treatment-related dizziness, or adverse events leading to dose reduction or discontinuation were observed as of the data cut-off date in the 35 patients enrolled.

• Most treatment-related adverse events (TRAEs) were low-grade and manageable, with the most frequent TRAE being grade 1 fatigue reported in 11% (4/35) of patients.

As of the data cut-off date, 21 patients with NSCLC were response-evaluable by investigator assessment with duration of treatment ranging from one to more than eight months (median 3.6 months). Objective responses (RECIST 1.1) were observed across all dose levels evaluated, including in:

• Heavily pre-treated patients: Partial Responses (PRs) were observed in 48% (10/21) of all response-evaluable patients, with 76% (16/21) continuing on treatment. Responses were observed in 53% (9/17) of patients who received two or more prior TKIs and one or more prior lines of chemotherapy, in 50% (9/18) of patients previously treated with lorlatinib or repotrectinib, and across all dose levels evaluated.

• Patients with ROS1 G2032R resistance mutation: Of nine patients with known ROS1 G2032R resistance mutation, responses were observed in 78% (7/9), including in two of three patients previously treated with repotrectinib, and tumor shrinkage was observed in 100% (9/9). Notably, complete clearance of G2032R allele was observed in all seven patients with G2032R detected on central ctDNA analysis.

• Patients with CNS metastases: Intracranial PRs were observed in 100% (3/3) patients with measurable (>10 mm) CNS metastases. Responses were observed in 73% (8/11) of patients with a history of CNS metastases, and no CNS progression was observed in any of the 35 treated patients.

As of the data cut-off date, 76% (16/21) of response-evaluable patients continued on NVL-520 treatment. Enrollment in the Phase 1 portion of the trial is ongoing.

These data will also be presented today in the “New Drugs on the Horizon” oral plenary session at the 34th EORTC-NCI-AACR (ENA) Symposium in Barcelona, Spain.
