First-in-Human Study of ICT01 in Patients With Advanced Cancer

Brief Summary
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.

7. Within 4 weeks of major surgery
8. Documented history of active autoimmune disorders requiring systemic immunosuppressive therapy within the last 12 months
9. Primary or secondary immune deficiency
10. Active and uncontrolled infections requiring intravenous antibiotic or antiviral treatment
