In Part 1, the investigational drug being evaluated (called INCB161734) will be evaluated alone (as monotherapy).

  • Part 1a will involve a dose escalation of INCB161734 as monotherapy.
  • Part 1b will invove dose expansion of INCB161734 as monotherapy.
  • Part 1c will study INCB161734's pharmacodynamics.

In Part 2, INCB161734 will be evaluated with other anti-cancer therapies including Cetuximab and Retifanlimab which are both monoclonal antibodies.
