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.
