Pierre Dodion, Chief Medical Officer of Innate Pharma, said: "There is evidence to suggest that the immune system plays a key role in ovarian cancer. Furthermore, there is a body of data indicating that ovarian cancers may at least partly escape immune surveillance via expression of HLA-E, the ligand of NKG2A. Once a patient relapses after first line treatment, the disease is ultimately fatal in virtually all cases. In addition, the development of new active agents in ovarian cancer has been slow. We are therefore very enthusiastic to test IPH2201 in patients with such a high medical need".
This is the second out of four trials announced by Innate Pharma, included in the frame of the global co-development and commercialization agreement signed with AstraZeneca for IPH2201 in April 2015. The first trial (IPH2201-201) is an open label Phase II trial testing IPH2201 as a single agent in a pre-operative setting of squamous cell carcinoma of the oral cavity (OCSCC). The first patient was treated at the Charité Comprehensive Cancer Center (CCCC), Berlin, Germany, in December 2014.
As part of Innate’s program, two further trials, testing IPH2201 in combination with ibrutinib in patients with Chronic Lymphocytic Leukemia, and with cetuximab in patients with Head and Neck cancer, will start in 2015. The initial development plan also includes Phase II combination clinical trials with IPH2201 and durvalumab (MEDI4736), an anti-PD-L1 immune checkpoint inhibitor, in solid tumors, which will be performed by AstraZeneca.
