Overview
Brief Summary
This is an open label, dose escalation and expansion Phase I/II study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity, and preliminary efficacy of CM350 in patients with advanced solid tumors.
The phase I study consists of a dose escalation phase and a dose expansion phase The safety and tolerability of CM350 and the maximum tolerated dose (MTD) (if applicable) will be evaluated in dose escalation phase.
The recommended phase 2 dose (RP2D) of CM350 will be determined in dose expansion phase.
The phase II study is to evaluate the efficacy of CM350 at the recommended phase 2 dose (RP2D) for advanced glypican-3 (GPC3)-positive solid tumors.

- •Note: For palliative radiotherapy to non-central nervous system lesions (total radiotherapy duration ≤14 days) to improve symptoms, a minimum washout period of 7 days before the first dose is required.

- •Patients who have previously received any therapy targeting GPC3, including but not limited to monoclonal antibodies, peptide vaccines, CAR-T, and bispecific antibodies.
- •Received chronic systemic corticosteroid therapy (daily intake of more than 10 mg prednisone or equivalent doses of other corticosteroids) or any other form of immunosuppressive treatment within 7 days before the first dose of CM
- •Known active central nervous system metastases. Note: Participants with previously treated brain metastases that have been stable for at least 14 days before the first dose (confirmed by repeat imaging at least 4 weeks apart, with the repeat imaging conducted during the screening period) may be considered for enrollment.
- •Participants with uncontrolled pleural effusion, ascites, or pericardial effusion as assessed by the investigator.
- •History of other malignancies within 5 years before the first dose of CM350, excluding cured basal cell or squamous cell carcinoma of the skin, cervical carcinoma in situ, or ductal carcinoma in situ of the breast.
- •Presence of active infection at screening as assessed by the investigator.
Arms & Interventions
Dose escalation phase in phase I
There are 11 target dose levels in dose escalation phase.
Intervention: CM350 group1
Dose expansion phase in phase I
Three or four doses will be selected for further evaluation in dose expansion phase to determine the RP2D (recommended phase 2 dose).
Intervention: CM350 group2
Phase II
The efficacy of CM350 will be evaluated at RP2D (recommended phase 2 dose) for advanced GPC3-positive solid tumors.
Intervention: CM350 group3
