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

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.
