Phase 1/2, dose escalation and expansion study designed to evaluate the safety and tolerability of 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 determine the RP2D and, if applicable, the MTD of NVL-655 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 NVL-655 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 NVL-655 in patients with advanced ALK-positive NSCLC and other solid tumors.
Condition or disease | Intervention/treatment | Phase |

Locally Advanced Solid Tumor Metastatic Solid Tumor | Drug: NVL-655 | Phase 1 Phase 2 |
In Phase 2, study patients will be enrolled into 4 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, brigatinib)
- Cohort 2b: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who have received 2-3 prior 1st or 2nd-generation ALK TKIs (crizotinib, ceritinib, alectinib, brigatinib)
- Cohort 2c: Patients with locally advanced or metastatic NSCLC harboring an ALK rearrangement, who have received 2-3 prior ALK TKIs, with lorlatinib in the 2nd or 3rd line
- Cohort 2d: Patients with other solid tumors harboring an ALK rearrangement or activating ALK mutation, including patients with NSCLC not eligible for cohorts 2a-c, who have received ≥1 prior systemic anticancer therapy, or for whom no satisfactory standard therapy exists
