Is this trial a fit for you?

Likely a good fit

Adults with measurable, locally advanced or metastatic KRAS‑mutant solid tumors who have ECOG performance status 0–1 and adequate organ function, and who are not pregnant and have no active CNS disease, are the intended participants.

Probably not a fit

Patients with active brain metastases or CNS involvement, significant cardiovascular or uncontrolled medical conditions, recent major surgery, pregnancy or lactation, or problems affecting drug absorption are unlikely to be eligible or to benefit.

What this trial studies

This Phase 1 interventional study tests TLN-372 as a single agent and in combination with cetuximab or pembrolizumab in adults with locally advanced or metastatic KRAS‑mutant solid tumors. The primary goals are to define safety, pharmacokinetics, and preliminary anti‑tumor activity in patients with measurable disease, ECOG 0–1, and adequate organ function. Key exclusions include active brain metastases or CNS involvement, recent major surgery, significant cardiovascular disease, pregnancy or lactation, and conditions that could affect drug absorption. The trial is sponsored by Treeline Biosciences and is being conducted at U.S. cancer centers including Dana‑Farber, University of Alabama at Birmingham, and START Midwest.

Why it matters

Potential benefit: If successful, TLN-372 could provide a new targeted option to shrink or control tumors in patients with KRAS‑mutant cancers that have limited current therapies.

How similar studies have gone: Some KRAS‑targeted drugs (notably for G12C mutations) have shown clinical benefit, but broader KRAS targeting remains challenging and combination strategies with immunotherapy or EGFR inhibitors have shown only early promising signals.
