A Study of Neladalkib (NVL-655) in Patients With Advanced NSCLC and Other Solid Tumors Harboring ALK Rearrangement or Activating ALK Mutation (ALKOVE-1)

A Phase 1/2 Study of the Selective Anaplastic Lymphoma Kinase (ALK) Inhibitor NVL-655 in Patients With Advanced NSCLC and Other Solid Tumors (ALKOVE-1)

Phase 1/2, dose escalation and expansion study designed to evaluate the safety and tolerability of neladalkib (NVL-655), determine the recommended phase 2 dose (RP2D), and evaluate the antitumor activity in patients with advanced ALK- positive (ALK+) NSCLC and other solid tumors.

Phase 1 will evaluate the overall safety and tolerability of neladalkib and will determine the RP2D and, if applicable, the maximum tolerated dose (MTD) of neladalkib in patients with advanced ALK+ solid tumors.

Phase 2 will determine the objective response rate (ORR) as assessed by Blinded Independent Central Review (BICR) of neladalkib at the RP2D. Secondary objectives will include the duration of response (DOR), time to response (TTR), progression-free survival (PFS), overall survival (OS), and clinical benefit rate (CBR) of neladalkib in patients with advanced ALK-positive NSCLC and other solid tumors.

A drug-drug interaction (DDI) sub-study will determine the effect of neladalkib on the pharmacokinetics of midazolam and repaglinide, as well as the effect of itraconazole on the pharmacokinetics of neladalkib, in patients with advanced ALK-positive NSCLC

In Phase 2, study patients will be enrolled into 6 distinct cohorts:

• Cohort 2a: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement who have received 1 prior 2nd-generation ALK TKI (ceritinib, alectinib, or brigatinib). Up to 2 prior lines of chemotherapy and/or immunotherapy are allowed.
• Cohort 2b: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who have received 2-3 prior ALK TKIs (crizotinib, ceritinib, alectinib, brigatinib, or lorlatinib). Up to 2 prior lines of chemotherapy and/or immunotherapy are allowed.
• Cohort 2c: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who have received lorlatinib as the only prior ALK TKI therapy. Up to one prior line of chemotherapy and/or immunotherapy received prior to lorlatinib is allowed.
• Cohort 2d: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who are naïve to ALK TKI therapy. Up to one prior line of chemotherapy and/or immunotherapy is allowed.
• Cohort 2e: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, not eligible for other Phase 2 cohorts.
• Cohort 2f: Patients with other solid tumors harboring an ALK rearrangement or activating ALK mutation, who have received ≥1 prior systemic anticancer therapy, or for whom no satisfactory standard therapy exists.

In the DDI sub-study, study patients will be enrolled into 2 distinct cohorts:

• Cohort G (DDI sub-study with midazolam and repaglinide): Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement who have received ≥1 prior ALK TKI.
• Cohort H (DDI sub-study with itraconazole): Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement who have received ≥1 prior ALK TKI.
