Summary

This trial tests the safety and effectiveness of two cancer treatments, HFB200603 and tislelizumab, in patients with advanced cancers.

Who is the study for?
Adults with certain advanced cancers (stomach, lung, colorectal, kidney cancer, melanoma) who've had specific prior treatments can join. They need a site for biopsy and measurable disease by RECIST 1.1 standards. A good performance status is required (0 or 1), and they must not have had recent cancer therapy or major surgery, no active autoimmune diseases or severe medical conditions.
What is being tested?
The trial tests HFB200603 alone and with Tislelizumab in two parts: dose-escalation to find safe levels and expansion where those doses are given based on the participant's cancer type. The goal is to determine safety and tolerability of these drugs in combination or as monotherapy.
What are the potential side effects?
Potential side effects may include reactions similar to other monoclonal antibodies such as immune-related issues, infusion reactions like CRS, organ inflammation, fatigue, digestive problems; specifics will be monitored throughout the study.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Dose Expansion - HFB200603 monotherapy (optional)Experimental Treatment1 Intervention
Participants will be administered HFB200603 at monotherapy RDE as an intravenous infusion.
Group II: Dose Expansion - HFB200603 in combination with tislelizumabExperimental Treatment2 Interventions
Participants will be administered HFB200603 in combination with tislelizumab at combination RDEs as an intravenous infusion. Based on the cancer type, participants will be randomized to combination HFB200603 RDE 1 or RDE 2.
Group III: Dose Escalation - HFB200603 monotherapyExperimental Treatment1 Intervention
Participants will be administered HFB200603 at dose levels 1-4 as an intravenous infusion to determine the Recommended Dose for Expansion (RDE).
Group IV: Dose Escalation - HFB200603 in combination with tislelizumabExperimental Treatment2 Interventions
Participants will be administered HFB200603 at dose levels 1-3 in combination with one dose level of tislelizumab as an intravenous infusion to determine the combination Recommended Doses for Expansion (RDEs).
