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.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Nuvalent Inc (NUVL) is the sponsoring company for this trial. BiotechSign currently grades this company F (22/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
