About IPH5201

IPH5201 is a CD39-blocking monoclonal antibody that may promote antitumor immunity by increasing immunostimulatory ATP and reducing immunosuppressive adenosine levels in the tumor microenvironment. It is being developed in partnership with AstraZeneca.

A first-in-human, multi-centre, non-randomised, open-label, phase 1 study (NCT04261075) sponsored by AstraZeneca assessed the safety, efficacy, pharmacokinetics and pharmacodynamics of IPH5201 as monotherapy and in combination with durvalumab in patients with advanced solid tumors.

A Phase 2 clinical trial conducted by Innate in lung cancer is in planning.

About IPH5301

IPH5301 is a CD73-blocking monoclonal antibody currently in an investigator-sponsored Phase 1 trial in collaboration with the Institut Paoli-Calmettes (IPC) and Oncodistinct Network.
