ClinicalTrials ID:NCT04243499

Patient View

This trial evaluates ICT01, a humanized anti-BTN3A monoclonal antibody, in advanced cancer patients. It includes dose escalation and cohort expansion phases, with ICT01 alone or combined with pembrolizumab. Eligible participants have relapsed/refractory cancer, ECOG ≤ 1, life expectancy > 3 months, and measurable lesions.

Patient Parameters

Program Overview

Part 1 will be a dose escalation study of IV ICT01 (a monoclonal antibody targeting BTN3A) as monotherapy in patients with advanced solid or hematologic tumors, followed by a cohort examining the combination of ICT01 plus pembrolizumab (Keytruda). Part 2 will be a cohort expansion into 2 solid tumor indications and one hematologic malignancy for ICT01 monotherapy, and 3 solid tumor indications for the combination of ICT01 plus pembrolizumab.
