First-in-Human Study of ICT01 in Patients With Advanced Cancer (EVICTION)

A First-in-human, Two-part Clinical Study to Assess the Safety, Tolerability and Activity of IV Doses of ICT01 as Monotherapy and in Combination With a Checkpoint Inhibitor, in Patients With Advanced-stage, Relapsed/Refractory Cancer

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.
