An oral drug targets a specific gene flaw in Hard-to-Treat tumors
NCT ID NCT06796699
First seen Oct 02, 2026 · Last updated Oct 02, 2026
Summary
Researchers are testing an experimental oral drug called GH56 in people with advanced solid tumors that have lost the MTAP gene. The trial enrolls adults and adolescents whose cancer has progressed after standard treatment or who have no standard options left. The study first finds a safe dose, then expands to more participants to look for early signs that the drug shrinks tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- GH56 capsule, an experimental oral cancer drug
- What this could lead to
- If GH56 works, it could offer an oral treatment option for advanced solid tumors with an MTAP deletion, a group that often has few targeted choices.
- What could go wrong
- This is an early-phase trial, so researchers mainly check safety and dosing rather than whether the drug extends life. Many experimental cancer drugs fail at this stage, and GH56 may cause side effects or show too little benefit.

Inclusion Criteria: 1. Willing to participate in the clinical trial, understand and sign the informed consent, and comply with the study visits and procedures. 2. Male and female patients who are ≥12 years of age at consent . 3. Histologically or cytologically confirmed advanced and/or metastatic malignancies with progression on / intolerance to standard treatment or lack of effective standard treatment. 4. Evidence of MTAP loss or homozygous MTAP/CDKN2A deletion in tumor tissue. 5. At least one measurable lesion as per RECIST v1.1 criteria. 6. Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1. 7. Survival expectations ≥ 12 weeks. 8. Adequate organ function 9. Has a negative serum pregnancy test result at screening and is able to comply with contraceptive-barrier requirements. Exclusion Criteria: 1. Subject has not recovered from a prior surgical procedure or has undergone any major surgery within 4 weeks prior to the first dose. 2. Has received any anti-tumor agents within 28 days without delayed toxicity for the treatment of advanced tumors prior to the first administration of GH56 Capsule 3. Has symptomatic or active progressive central nervous system (CNS) metastases such as molluscum contagiosum metastases. 4. Subjects who have difficulty in swallowing and have a history of gastrointestinal surgery or other relevant medical disorders that may interfere with the absorption of GH56. 5. Subjects had a malignant tumor other than the current tumor within 5 years prior to the first administration of GH56 Capsule, except for localized cancers that have been apparently cured or without disease progression or recurrence for at least 5 consecutive years. 6. Uncontrolled or significant cardiovascular disease 7. Subjects with documented positive virology status of hepatitis, as confirmed by Screening hepatitis B virus (HBV) and hepatitis C virus (HCV) tests, Human Immunodeficiency Virus (HIV). 8.
