A Study of NVL-330 in Patients With Advanced or Metastatic HER2-altered NSCLC (HEROEX-1)

Summary

Phase 1a/1b dose escalation and expansion study designed to evaluate the safety and tolerability of NVL-330, determine the recommended Phase 2 dose (RP2D), and evaluate the antitumor activity in participants with advanced or metastatic human epidermal growth factor receptor 2 (HER2) -altered non-small lung cancer (NSCLC). Phase 1a dose escalation is designed to assess the safety and tolerability of NVL-330 and to select the candidate RP2D(s) and, if applicable, the MTD. Phase 1b expansion is designed to further evaluate the overall safety and tolerability of the candidate RP2D(s) of NVL-330 and to determine the RP2D of NVL-330 in participants with advanced or metastatic HER2 mutant NSCLC.

Eligibility

Inclusion Criteria:

1. Age ≥ 18 years
2. Histologically or cytologically confirmed locally advanced or metastatic NSCLC
3. Documented HER2 status as follows:

   1. Phase 1a: Documented oncogenic HER2 mutation such as HER2 exon20 insertion mutations or single nucleotide variants or HER2 amplification.
   2. Phase 1b: Documented oncogenic HER2 mutation.
4. Identification of lesions as follows:

   1. Phase 1a: Must have evaluable disease (target or nontarget) according to RECIST 1.1.
   2. Phase 1b: Must have measurable disease, defined as ≥ 1 radiologically measurable target lesion according to RECIST 1.1.
5. Adequate organ function and bone marrow reserve

Exclusion Criteria:

1. Participant's cancer has known oncogenic driver alteration other than HER2
2. Known allergy/hypersensitivity to excipients of NVL-330
3. Major surgery within 4 weeks of the first dose of study drug
4. Ongoing or recent anticancer therapy
5. Actively receiving systemic treatment or direct medical intervention on another therapeutic clinical study
