Proportion of patients achieving complete response (CR) or partial response (PR) as assessed by investigators according to RECIST v1.1. Responses must be confirmed by repeat imaging ≥4 weeks (±7 days) after the initial documentation.
| Arm | Type | Description |
|---|---|---|
| HER2-Positive Gastric Cancer | EXPERIMENTAL | Patients with HER2-positive advanced or metastatic gastric cancer will receive sintilimab (200 mg IV, Q3W) and pyrotinib (400 mg PO, QD), with or without chemotherapy. The investigator may choose from XELOX, SOX, or TS regimens based on clinical evaluation. |
| HER2-Positive Colorectal Cancer | EXPERIMENTAL | Patients with HER2-positive advanced or metastatic colorectal cancer will receive sintilimab (200 mg IV, Q3W) and pyrotinib (400 mg PO, QD), with or without chemotherapy. The recommended regimens include mFOLFOX6 or XELOX, at the investigator's discretion. |
| HER2-Positive Hepatocellular Carcinoma | EXPERIMENTAL | Patients with HER2-positive advanced or unresectable hepatocellular carcinoma will receive sintilimab (200 mg IV, Q3W) and pyrotinib (400 mg PO, QD), with or without chemotherapy. Chemotherapy may include FOLFOX or interventional locoregional therapies, as appropriate. |
| HER2-Positive Biliary Tract Cancer | EXPERIMENTAL | Patients with HER2-positive advanced or metastatic biliary tract cancer (including intrahepatic and extrahepatic cholangiocarcinoma, gallbladder cancer) will receive sintilimab (200 mg IV, Q3W) and pyrotinib (400 mg PO, QD), with or without chemotherapy. Suggested regimens include GC (gemcitabine + cisplatin) or GEMOX. |
| HER2-Positive Pancreatic Cancer | EXPERIMENTAL | Patients with HER2-positive advanced or metastatic pancreatic cancer will receive sintilimab (200 mg IV, Q3W) and pyrotinib (400 mg PO, QD), with or without chemotherapy. Optional chemotherapy regimens include FOLFIRINOX or AG (nab-paclitaxel + gemcitabine). |
