Study Endpoints

Primary Endpoints

Number of partcipants with Dose Limiting Toxicities (DLTs)
Throughout the dose escalation phase, an average of 1 year

The incidence of dose-limiting toxicity (DLT) at different doses of BC3195 combined with pembrolizumab in patients with locally advanced or metastatic solid tumors. DLT will be assessed at the end of Cycle 1.

Investigator-assessed Objective Response Rate (ORR) of BC3195 combined with pembrolizumab in participants with solid tumors
Throughout the dose expansion phase, an average of 2.5 years

ORR (per investigator's assessment based on RECIST v1.1) defined as the proportion of participants who achieve a best overall response (BOR) of complete response (CR) or partial response (PR).

Secondary Endpoints

Investigator-assessed progression-free survival (PFS) of BC3195 combined with pembrolizumab in participants with solid tumors
Through study completion, an average of 2.5 years
Investigator-assessed disease control rate (DCR) of BC3195 combined with pembrolizumab in participants with solid tumors
Through study completion, an average of 2.5 years
Investigator-assessed duration of response (DOR) of BC3195 combined with pembrolizumab in participants with solid tumors
Through study completion, an average of 2.5 years

ArmTypeDescription
BC3195 in Combination with PembrolizumabEXPERIMENTALThe study is divided into two phases: the dose escalation phase (Phase I): BC3195 (with 3 preset dose cohorts: 1.8mg/kg, 2.1mg/kg, 2.4mg/kg Q3W) combined with pembrolizumab (200mg Q3W) will be enrolled sequentially; the dose expansion (Phase II) phase: the recommended Phase 2 dose (RP2D) for BC3195 from the dose escalation phase combined with pembrolizumab (200mg Q3W) will be used in 4 cohorts (NSCLC / TNBC / HNSCC /others).

Interventions

NameTypeDescription
BC3195DRUGBC3195 for injection is a sterile lyophilized powder in a 20 mg single-dose vial. Administration: Administered via intravenous (IV) infusion, with dosing and frequency determined according to Phase I (dose escalation) and Phase Ⅱ(dose expansion) study design
Pembrolizumab/KEYTRUDA®DRUGPembrolizumab will be administered at 200 mg as a 30 minute IV infusion Q3W prior to BC3195. Sites should make every effort to target infusion timing to be as close to 30 minutes as possible.
