A Phase 1a/1b, Open-Label, Multi-Center, Dose Escalation and Expansion Study of HFB200301 (TNFR2 Agonist Antibody) as a Single Agent and in Combination With Tislelizumab (Anti-PD-1 Antibody) in Adult Patients With Advanced Solid Tumors
Description
Brief Summary
The purpose of this study is to test the safety and tolerability of HFB200301 as a single
agent and in combination with tislelizumab in patients with advanced cancers. There are two
parts in this study. During the escalation part, groups of participants will receive
increasing doses of HFB200301 as a monotherapy or in combination with tislelizumab until a
safe and tolerable dose of HFB200301 as a single agent or combination therapy is determined.
During the expansion part, participants will take the dose of HFB200301 as a monotherapy or
in combination with tislelizumab 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.
Detailed Description
This is a Phase 1a/1b, first in human, open-label, dose escalation and expansion study in
adults with advanced cancers. The study will comprise of
1. A Screening Period
2. A Treatment Period during which participants will receive the study drug on the first
day of each cycle
3. A Follow-up Period
Phase
