Brief Title: TTX-030 in Combination With Immunotherapy and/or Chemotherapy in Subjects With Advanced Cancers

Phase 1/1b Study to Evaluate the Safety and Activity of TTX-030 (Anti-CD39) in Combination With Pembrolizumab or Budigalimab and/or Chemotherapy in Subjects With Advanced Solid Tumors


  • Org Study ID: TTX-030-002
  • Secondary ID: N/A
  • NCT ID: NCT04306900
  • Sponsor: Trishula Therapeutics, Inc.


This is a phase 1/1b study of TTX-030 in combination therapy, an antibody that inhibits CD39 enzymatic activity, leading to accumulation of pro-inflammatory adenosine triphosphate (ATP) and reduction of immunosuppressive adenosine, which may change the tumor microenvironment and promote anti-tumor immune response.

This trial will study the safety, tolerability, pharmacokinetics, pharmacodynamics and anti-tumor activity of TTX-030 in combination with immunotherapy and/or standard chemotherapies.
