Summary

1. Primary Objectives (1) To evaluate the safety and tolerability of sacituzumab tirumotecan in combination with pucotenlimab in patients with advanced cholangiocarcinoma; (2) To assess the objective response rate (ORR) of sacituzumab tirumotecan combined with pucotenlimab in patients with unresectable or metastatic cholangiocarcinoma, as evaluated by investigators per RECIST v1.1;
2. Secondary Objectives (1) To evaluate the overall survival (OS) of sacituzumab tirumotecan combined with pucotenlimab in advanced cholangiocarcinoma; (2) To assess progression-free survival (PFS), disease control rate (DCR), duration of response (DOR), and time to response (TTR) in patients treated with sacituzumab tirumotecan combined with pucotenlimab, as determined by investigators based on RECIST v1.1; (3) To further evaluate PFS (as a standalone secondary endpoint);
3. Exploratory Objectives (1) To investigate the correlation between TROP2 expression, systemic immune biomarkers, and treatment efficacy.

Conditions

Interventions

DRUG

Sacituzumab tirumotecan (iv)+Putolizumab injection (iv)

When administering sacituzumab tirumotecan and putolizumab on the same day, the drugs should be given sequentially. Putolizumab is administered first. For the first co-administration, a 4-hour interval is required. If no severe infusion reactions or allergic reactions occur, subsequent administrations may proceed with a minimum interval of 60 minutes before administering sacituzumab tirumotecan. Putolizumab dosing: Dosage: 200 mg, intravenous (IV) infusion Dosing cycle: Every 3 weeks (administered on Day 1 of each cycle) Dose interruptions due to adverse events (AEs): Refer to the prescribing information. Sacituzumab tirumotecan dosing: Dosage: 4 mg/kg, intravenous (IV) infusion Dosing cycle: Every 2 weeks (administered on Day 1 of each cycle, with a permissible dosing window of 14 ± 3 days between doses) Dose interruptions due to adverse events (AEs): Refer to the prescribing information.
