A Phase I, First in Human Study of CBA-1205, Anti-DLK1 Monoclonal Antibody in Patients with Advanced Solid Tumors and Hepatocellular Carcinoma (HCC)

Phase 1
Recruiting
Conditions
Hepatocellular Carcinoma (HCC)
Solid Tumors
Interventions
Registration Number
NCT06636435
Lead Sponsor
Chiome Bioscience Inc.
Brief Summary

In this first-in-human, multicenter,non-randomized, open-label, standard 3+3 dose escalation Phase I study encompasses 3parts(Part1-3). The purpose of this FIH study is to evaluate the safety and tolerability profile of CBA-1205.

Detailed Description

To evaluate safety and efficacy of CBA-1205 in the following three parts in a stepwise manner:

* In Part 1, safety and tolerability in patients with solid tumor where no standard treatment is available, or who are intolerable or non-responder to the standard treatment will be evaluated. Initial dose for Part 2 will be determined.

* In Part 2, safety and tolerability in patients with advanced and/or recurrent hepatocellular carcinoma which are unresectable, or who are intolerable or non-responder to the standard treatment will be evaluated. Recommended dose in this population will be determined.

* In Part 3, safety and efficacy at the recommended dose in patients with advanced and/or recurrent hepatocellular carcinoma which are unresectable, or who are intolerable or non-responder to the standard treatment will be evaluated.

* PK analysis
