Assess the Safety and Activity of Combined MG005 and Sorafenib (NEXAVAR®) Treatment With Solid Tumor

• Status: Completed
• Trial end date: 2020-07-24
• Target enrollment: 0
• Participant gender: All

Summary

The proposed initial trial is a Phase I, open label study to evaluate the safety and explore efficacy of MG005 in combination with sorafenib in patients with solid tumor. The eligible patients will receive 200 mg of sorafenib with 3 pre-defined dose levels of GW5074, escalated from 750 mg to 1500 mg (daily dose), to determine the Maximum Tolerated Dose (MTD) and dose limiting toxicities (DLT) (if any) at Phase I stage.

• Phase: Phase 1
• Accepts Healthy Volunteers?: No
