MARSEILLE, France, Nov. 14, 2013 (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, announces that a new set of preclinical data on lirilumab will be
presented in a poster at the upcoming 55th ASH Annual Meeting (December 7-10,
2013) in New Orleans, LA:

"Anti-KIR Antibody Enhancement Of Anti-Lymphoma Activity Of Natural Killer
Cells As Monotherapy and In Combination With Anti-CD20 Antibodies"
Session Name: 625. Lymphoma: Pre-Clinical - Chemotherapy and Biologic Agents:
Poster III
Date:Monday, December 9, 2013
Presentation Time: 6:00 PM - 8:00 PM
Location: Ernest N. Morial Convention Center, Hall G

The abstract is available on the meeting website.

Lirilumab is a natural killer (NK) cell checkpoint inhibitor undergoing
clinical development with partner Bristol-Myers Squibb in Acute Myeloid
Leukemia in monotherapy and in combination settings in solid tumors. The new
preclinical results are from research conducted by Dr Holbrook Kohrt from
Stanford University, Innate Pharma and CIML^1. They support the monotherapy
activity of lirilumab in mouse models of lymphoma, through the enhancement of
NK cell cytotoxicity. Furthermore, the new data showed that in combination
with the anti-CD20 antibody rituximab*, lirilumab enhanced NK cell-mediated,
antibody-dependent cellular cytotoxicity (ADCC) against lymphoma in vitro and
in vivo in mouse models. Taken together, these data reinforce the rationale
for the development of lirilumab in onco-hematology, and open new perspectives
for the combination of lirilumab with antibody drugs active through ADCC. 

Nicolai Wagtmann, CSO of Innate Pharma, said: "What is particularly exciting
and impressive about these new preclinical results is that we show that
lirilumab, beyond single-agent activity, also enhanced the efficacy of
rituximab in vivo through ADCC. These results raise the possibility that
lirilumab may similarly enhance the ADCC-activity of other therapeutic
antibodies currently marketed or in clinical development in cancer and other

About lirilumab (IPH2102/BMS-986015):

Lirilumab 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.

Lirilumab is licensed to Bristol-Myers Squibb Company (NYSE:BMY) by Innate
Pharma. As part of the license agreement, 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 AML.

Lirilumab is currently tested in a randomized, double-blind,
placebo-controlled Phase II trial in elderly patients with AML in a
maintenance setting. In addition, two phase I trials are ongoing in solid
tumors, testing lirilumab in combination-therapy with ipilimumab (anti-CTLA4)
and nivolumab (anti-PD-1, BMS-936558), respectively.
