Innate Pharma SA (the "Company" - Euronext Paris: FR0010331421 - IPH) today announces that safety data for two Phase I studies of lirilumab in combination with nivolumab or ipilimumab conducted by Bristol-Myers Squibb in patients with advanced refractory solid tumors will be presented by Dr. Neil H.

The abstract is now available on the ESMO website at this link .

About the poster:

Title: "Safety of the natural killer (NK) cell-targeted anti-KIR Antibody, lirilumab (liri), in combination with nivolumab (nivo) or ipilimumab (ipi) in two phase 1 studies in advanced refractory solid tumors"

Category: Immunotherapy of cancer
Poster: 1086P
Date:  Sunday, October 9, 2016
Presentation Time: 1:00 PM - 2:00 PM
Presenter: Dr. Neil H. Segal, Memorial Sloan-Kettering Cancer Center
Location: Bella Center, Hall E, Copenhagen

About the Phase I trials of lirilumab in combination with nivolumab (anti-PD-1) or ipilimumab (anti-CTLA4) in solid tumors:

The two reported Phase I studies evaluated escalating doses of lirilumab in combination with nivolumab or ipilimumab. In the first study, lirilumab 0.1 to 3 mg/kg every 4 weeks was combined with nivolumab 3 mg/kg every 2 weeks for up to 2 years. In the second study, lirilumab 0.1 to 3 mg/kg every 3 weeks was combined with ipilimumab 3 mg/kg every 3 weeks for 4 doses and then every 12 weeks for 4 doses.

The purpose of these Phase I open label studies is to determine the safety of the combination of lirilumab with nivolumab or ipilimumab respectively and to provide preliminary information on the clinical activity of these combinations.

The primary outcome is safety. Secondary outcomes include a preliminary assessment of efficacy. The trials are being conducted in two parts - dose escalation and cohort expansion.

About lirilumab (IPH2102/BMS-986015):

Lirilumab is a fully human monoclonal antibody that is designed to act as a checkpoint inhibitor by blocking the interaction between KIR2DL-1,-2,-3 inhibitory receptors and their ligands. Blocking these receptors facilitates activation of NK cells and, potentially some subsets of T cells, ultimately leading to destruction of tumor cells.

Lirilumab is licensed to Bristol-Myers Squibb Company. 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 conducts the development of lirilumab through Phase II in acute myeloid leukemia ("AML").

Innate is currently testing lirilumab in a randomized, double-blind, placebo-controlled Phase II trial as maintenance treatment in elderly patients with AML in first complete remission ("EffiKIR" trial). In addition, lirilumab is also being evaluated by Bristol-Myers Squibb in clinical trials in combination with other agents in a variety of tumor types.
