Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with advanced solid tumors that have an MTAP gene deletion.

Probably not a fit

Patients with solid tumors that do not have an MTAP gene deletion or those who are not eligible for the study criteria may not benefit.

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

What this trial studies

This clinical trial evaluates the safety and effectiveness of GH56 capsules in patients with advanced solid tumors that have a deletion of the MTAP gene. It is a multicenter, single-arm study that consists of two phases: a dose-escalation phase (Ia) to determine the appropriate dosage and a dose-expansion phase (Ib) to further assess the treatment's effects. Participants must have previously failed standard treatments or have no available standard therapies. The study aims to gather data on the drug's pharmacokinetics, pharmacodynamics, and preliminary anti-tumor activity.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors lacking the MTAP gene.

How similar studies have gone: While there may be limited data on this specific approach, similar studies targeting genetic deletions in tumors have shown promise in the past.
