The goal of this interventional clinical trial is to learn about TNG260, a CoREST inhibitor, in combination with pembrolizumab in patients with advanced solid tumors with a known STK11 mutation. The main question\[s\] it aims to answer are: * the recommended dose for Phase 2 * to evaluate the safety and tolerability of the combination therapy * to determine the pharmacokinetics of TNG260 * to evaluate the initial antineoplastic activity Participants will receive study treatment until they experience an undesirable side effect, their disease progresses or until they withdraw consent.
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.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Tango Therapeutics, Inc. (TNGX) is the sponsoring company for this trial. BiotechSign currently grades this company D (49/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
