Fruquintinib in Combination With Sintilimab in Patients With Advanced Solid Tumor

• Status: Recruiting
• Trial end date: 2021-07-01
• Target enrollment: 0
• Participant gender: All

Summary

This study is composed of dose escalation stage and dose expansion stage. In dose escalation stage, patients with advanced solid tumor will be enrolled and administrated with Fruquintinib in combination with Sintilimab. The MTD ( maximum tolerated dose) or RP2D ( Recommended Phase 2 Dose) will be determined in this stage. In dose expansion stage, additional patients will be enrolled and be treated at RP2D to evaluate the safety, tolerability and efficacy.

• Phase: Phase 1/Phase 2

The standard treatment requirements for patients with hepatocellular carcinoma, renal cell carcinoma, endometrial cancer and gastrointestinal tumors (gastric adenocarcinoma, gastroesophageal junction adenocarcinoma and colorectal adenocarcinoma) are as follows:

• Patients with hepatocellular carcinoma have received a molecular targeted therapy (sorafenib or lenvatinib) or/and systemic chemotherapy (arsenite monotherapy or oxaliplatin-based combination drugs);
