Intervention model description: This is an open-label, multi-center, multi-cohort, phase Ib/II clinical trial, divided into 8 cohorts according to tumor types. Cohorts 1-4 are SYHA1813 combined with different regimens, including safety run-in stage and cohort expansion stage. Cohorts 5-8 are SYHA1813 monotherapy and only include the expansion cohorts. In the expansion stage, cohorts 1-6 are single-arm studies, cohorts 7-8 are randomized controlled studies.
Primary purpose: TREATMENT

Brief summary: This is an open-label, multi-center, multi-cohort, phase Ib/II clinical trial, divided into 8 cohorts according to tumor types. Cohorts 1-4 are SYHA1813 combined with different regimens, including safety run-in stage and cohort expansion stage. Cohorts 5-8 are SYHA1813 monotherapy and only include the expansion cohorts. The primary objective was to evaluate the safety and efficacy of SYHA1813 single agent or in combination with different regimens in unresectable locally advanced or metastatic solid tumors.

Detailed description: In the safety run-in stage, the "3+3" design is used to evaluate the tolerability and safety of different dose levels combined with different regimens, and the observation period of DLT is set as the first treatment cycle. After 3 DLT-evaluable participants at each dose level completed the DLT observation period, the safety of the dose level is evaluated by an SMC consisting of the investigator and the sponsor's medical monitor. Cohorts 1-4 enter the cohort expansion stage after determining the SYHA1813 dose regimen during the safety run-in stage. Cohorts 5-8 enter the cohort expansion stage directly. In the expansion stage, cohorts 1-6 are single-arm studies, the primary endpoint is ORR as evaluated by investigator according to RECIST 1.1. Cohorts 7-8 are randomized controlled studies, the primary endpoint is PFS as evaluated by investigator according to RECIST 1.1.
