A Study of HFB200301 in Adult Patients With Advanced Solid Tumors

• Status: Not yet recruiting
• Trial end date: 2024-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to test the safety and tolerability of HFB200301 in patients with advanced cancers. There are two parts in this study. During the escalation part, groups of participants will receive increasing doses until a safe and tolerable dose of HFB200301 is determined. During the expansion part, participants will take the dose of study drug that was determined from the escalation part of the study and will be assigned to a group based on the type of cancer the participants have.

• Phase: Phase 1
