A Study of Duvelisib Combined With SG001 Injection in Patient With Advanced Solid Tumors

Phase 1

Not yet recruiting

• Conditions: Advanced Solid Tumors
• Interventions: Drug: SG001; Drug: Duvelisib

• Registration Number: NCT05508659
• Lead Sponsor: CSPC ZhongQi Pharmaceutical Technology Co., Ltd.

Brief Summary

Study will be conducted with 2 stages.

Detailed Description

The first stage will explore the suitable dose of duvelisib when combined with SG001 injection in patients with advanced solid tumors who had failed with prior systemic therapy.

The second stage will explore the safety and tolerability, preliminary anti-tumor efficacy and PK data of duvelisib monotherapy and combo regime with SG001 injection in patients with advanced solid tumors which will including but not limited with esophageal carcinoma, gastric carcinoma, colorectal cancer and head and neck squamous carcinoma.
