• Anti-CD39 monoclonal antibody IPH5201 advances to Phase 2 study in lung cancer
  • Innate to receive $5M milestone payment from AstraZeneca

Regulatory News:

Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced that IPH5201, an anti-CD39 blocking monoclonal antibody developed in collaboration with AstraZeneca (LSE/STO/Nasdaq: AZN), will advance into a Phase 2 clinical trial in lung cancer. Innate will receive a $5M milestone payment from AstraZeneca and will be responsible for conducting the study. AstraZeneca and Innate will share study costs and AstraZeneca will supply clinical trial drugs.

“We are very pleased that our collaboration with AstraZeneca continues to advance with this Phase 2 trial of our anti-CD39, IPH5201. We are particularly excited about the progress of our assets targeting the adenosine pathway, which is increasingly recognized as critical in tumor immunosuppression. In addition to IPH5201, Innate’s anti-CD73 program, IPH5301 is in a Phase 1 study,” said Mondher Mahjoubi, Chief Executive Officer of Innate Pharma. “The decision to advance IPH5201 illustrates our growing late stage pipeline and progress in building a sustainable business, as well as the positive collaboration we have with AstraZeneca, which also includes two Phase 3 trials with monalizumab in non-small cell lung cancer and head and neck cancer.”

AstraZeneca conducted a Phase 1 trial in solid tumors with IPH5201 alone or in combination with durvalumab (PD-L1). The data are expected to be presented at an upcoming medical meeting in due course.

About IPH5201:

IPH5201 is a blocking antibody targeting the CD39 immunosuppressive pathway. CD39 is an extracellular enzyme that is expressed in the tumor microenvironment, on both tumor infiltrating cells and stromal cells in several cancer types. CD39 inhibits the immune system by degrading adenosine triphosphate (ATP) into adenosine monophosphate (AMP), that is then further degraded into adenosine by CD73. By promoting the accumulation of immune-stimulating ATP and preventing the production of immune-suppressive adenosine, the blockade of CD39 may stimulate anti-tumor activity.

About the Innate Pharma-AstraZeneca Multi-Term Agreement:

In October 2018, Innate Pharma and AstraZeneca entered into a development collaboration that included an option agreement for IPH5201, an anti-CD39 blocking monoclonal antibody. As part of the option agreement AstraZeneca paid Innate a $50m upfront payment for the option to the exclusive license to co-develop and co-commercialize IPH5201 and up to $825m in opt-in payments, development and commercial milestones and high-single to double-digit tiered royalties. Innate retains the right to receive profit sharing within the EU.
