This is a first-in-human (FIH), multicenter, open-label, phase I/Ⅱa clinical study of HMPL-A830 in participants with histologically or cytologically confirmed, unresectable, advanced, or metastatic solid tumors\*, who are refractory or progressed on/after available standard treatment. The study will be conducted in 2 parts: Dose Escalation (Part A, Phase I), approximately 57 participants will be enrolled. Dose Optimization (Part B, Phase IIa), approximately 90 participants will be enrolled.
Part A: To evaluate the safety, tolerability, and determine the maximum tolerated dose (MTD) and/or recommended dose(s) for optimization (RDO) of HMPL-A830 in previously treated participants with solid tumors. Part B: To characterize the safety, tolerability, and preliminary efficacy of HMPL-A830 at RDO(s) to determine recommended dose(s) for phase 2 (RP2D) or phase 3 (RP3D) in participants with selected solid tumors
Inclusion Criteria: 1. Understood this study and are able to voluntarily sign the informed consent form (ICF); 2. Male or Female, Age ≥ 18 years; 3. Histological confirmed, unresectable, advanced or metastatic solid tumor 4. Participants must have at least one measurable lesion per Response Evaluation Criteria in Solid Tumors(RECIST) v1.1 5. Life expectancy ≥ 12 weeks 6. Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0-1 Exclusion Criteria: 1. Use strong inhibitors of cytochrome P450 3A4 enzyme (CYP3A4), and inhibitors of P-glycoprotein (P-gp) and breast cancer resista…
Enrolled participants with solid tumors will receive HMPL-A830 treatment in a dose escalation setting at 6 predefined dose levels
Participants will be randomized in a 1:1 ratio to receive treatment in two RDO levels. Randomization will be stratified by tumor types.
