MARSEILLES, FRANCE -- (Marketwire) -- 12/19/12 -- Innate Pharma SA (the "Company") (EURONEXT PARIS: IPH) (FR0010331421), the innate immunity company developing first-in-class drugs for cancer and inflammatory diseases, today announces that a second Phase I combination trial for IPH2102/BMS-986015 was published on the NIH website ClinicalTrials.gov: http://www.clinicaltrials.gov/ct2/show/NCT01750580.

This trial follows the Phase I trial of IPH2102/BMS-986015 in combination with anti-PD-1 nivolumab (BMS-936558) announced in October and published on the NIH website ClinicalTrials.gov: http://www.clinicaltrials.gov/ct2/show/NCT01714739.

Marcel Rozencweig, Chief Medical Officer of Innate Pharma, said: "In this second Phase I trial, IPH2102/BMS-986015 will be tested in a variety of solid tumors, in combination with ipilimumab, the first approved immunomodulating antibody." He added: "With the Phase II trial in Acute Myeloid Leukemia and the Phase I in combination with anti-PD-1 nivolumab previously announced, the anti-KIR approach is undergoing wide early clinical testing".

About the Phase I trial with IPH2102/BMS-986015 in combination with ipilimumab in solid tumors:

The purpose of this Phase I open label study is to determine whether the combination of IPH2102/BMS-986015 and ipilimumab is safe and provide preliminary information on the clinical activity of the combination.

The primary outcome will be safety. Secondary outcomes will include a preliminary assessment of efficacy, as measured by tumor assessment. The study will be conducted in two parts -- dose escalation and cohort expansion -- and is expected to enroll approximately 150 patients. Tumor types will be restricted to the following advanced (metastatic and/or unresectable) tumor types: melanoma, non-small cell lung cancer -- squamous and non-squamous histology, and castrate resistant prostate cancer.

About IPH2102/BMS-986015:

IPH2102/BMS-986015 is a fully human monoclonal antibody blocking interaction between Killer-cell immunoglobulin-like receptors (KIR) on NK cells with their ligands. Blocking these receptors facilitates activation of NK cells and, potentially, destruction of tumor cells by the latter.

IPH2102/BMS-986015 is licensed to Bristol-Myers Squibb Company (NYSE: BMY). As part of the agreement between Innate Pharma and Bristol-Myers Squibb, Bristol-Myers Squibb holds exclusive worldwide rights to develop, manufacture and commercialize IPH2102/BMS-986015 and related compounds blocking KIR receptors, for all indications. Under the agreement, Innate Pharma will conduct the development of IPH2102/BMS-986015 through Phase II in Acute Myeloid Leukemia ("AML").

IPH2102/ BMS-986015 is currently tested in a randomized, double-blind, placebo-controlled Phase II trial in elderly patients with AML in a maintenance setting as well as in two combination Phase I trials in solid tumors, respectively with ipilimumab and with the anti-PD-1 antibody nivolumab (BMS-936558).
