Is this trial a fit for you?

Likely a good fit

Ideal candidates have unresectable or metastatic solid tumors listed (CRC, RCC with clear cell features, NSCLC non-squamous, BTC/GBC), measurable disease, and adequate organ function.

Probably not a fit

Patients without measurable disease, those with incompatible organ function, or those not meeting study criteria may not receive benefit from MK-4884.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 1 trial evaluating the safety and tolerability of MK-4884 in participants with unresectable or metastatic solid tumors. Eligible cancers include colorectal cancer, certain renal cancers, nonsquamous non-small cell lung cancer, and biliary tract/gallbladder cancers. The study will enroll participants with measurable disease and adequate organ function, including HIV- or HBV-positive individuals under specified control criteria. Dosing cohorts will help determine safe dose levels and potential dose-limiting toxicities. Sites include centers in Missouri, Texas, and Ontario.

Why it matters

Potential benefit: If successful, participants may receive a safe dose of MK-4884 and contribute to understanding its potential treatment value for their cancer type.

How similar studies have gone: Previous early-phase studies in similar targeted approaches have shown safety signals, but this exact approach with MK-4884 is exploratory.
