A Phase Ia/Ib Clinical Study of GH56 Capsules in Subjects With MTAP-Deleted Advanced Solid Tumors

March 25, 2025 updated by: Suzhou Genhouse Bio Co., Ltd.

A Multi-center, Single-Arm, Open-Label Phase Ia/Ib Clinical Study Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of GH56 Capsules in Subjects With MTAP-Deleted Advanced Solid Tumors

This is a multicenter, single-arm, open-label, dose-escalation, dose-expansion study to evaluate the safety, tolerability, PK/PD, and preliminary anti-tumor activity of GH56 Capsule in subjects with advanced solid tumors who have failed or are intolerant in standard treatment, or have no standard therapy. The clinical trial will be carried out in two parts: phase Ia study (dose escalation study) and phase Ib (dose expansion study).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

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. Men or women ≥18 years old.
  • 3. Men or women with MTAP-Deleted Advanced Solid Tumors.
  • 4. Subjects with solid tumors must have at least one evaluable lesion which should be measurable by RECIST v1.1.
  • 5. Eastern Cooperative Oncology Group (ECOG) performance status (Table 12) 0 to 1.
  • 6. Survival expectations ≥ 12 weeks.
  • 7. Subjects with adequate organ function and the laboratory test critera.
  • 8. Serum pregnancy test (for female of childbearing potential) negative within 7 days prior to first dosing of study treatment. Male and female subjects of childbearing potential must agree to use effective methods of contraception from the time of ICF signed, throughout the study and for 6 months after the last dose of the investigational product. A patient is of childbearing potential if, in the opinion of the Investigator, he/she is biologically capable of having children and is sexually active.

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. Known (including suspected) allergic to GH56 or its components.
  • 3. 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 or has received radiation therapy, biologic therapy, endocrine therapy, targeted therapy, immunotherapy, or other anti-tumor drug treatments within 28 days prior to the first administration of GH56 Capsule, or other anti-tumor drugs or treatments within the following interval before the first administration of GH56 Capsule.
