MARSEILLE, France, March 31, 2014 (GLOBE NEWSWIRE) -- Innate Pharma SA (the "Company" - Euronext Paris: FR0010331421 - IPH), the innate immunity company developing first-in-class drug candidates for cancer and inflammatory diseases, today announced the start of the cohort expansion portion of the Phase I clinical trial testing the combination of the two investigational checkpoint inhibitors lirilumab (anti-KIR) and nivolumab (anti-PD-1) in selected solid tumors.

Additional details are available at clinicaltrials.gov.

Lirilumab is licensed to Bristol-Myers Squibb Company (NYSE: BMY) and this Phase I trial is being conducted by Bristol-Myers Squibb.

About the Phase I trial with lirilumab (anti-KIR checkpoint inhibitor; BMS-986015) in combination with nivolumab (anti-PD-1 checkpoint inhibitor BMS-936558) in solid tumors:

The purpose of this Phase I open label study is to evaluate the safety of the combination of lirilumab and nivolumab and to provide preliminary information on the clinical activity of the combination. The primary outcome is safety. Secondary outcomes include a preliminary evaluation of efficacy, as measured by tumor assessment. It is conducted in two parts: dose escalation and cohort expansion. In the cohort expansion, patients will be dosed for up to two years.

About lirilumab:

Lirilumab is a fully human monoclonal antibody blocking interaction between Killer-cell immunoglobulin-like receptors (KIR) on natural killer (NK) cells and their ligands. Blocking these receptors facilitates activation of NK cells and, potentially, destruction of tumor cells by the latter.

Lirilumab is licensed to Bristol-Myers Squibb. As part of the agreement between Innate Pharma and Bristol-Myers Squibb, Bristol-Myers Squibb holds exclusive worldwide rights to develop, manufacture and commercialize lirilumab and related compounds blocking KIR receptors, for all indications. Under the agreement, Innate Pharma is conducting the development of lirilumab through Phase II in AML.
