*MICA validated as a novel target for antibody drug development in solid
  *IPH43 program now aims at selection and optimization of the best
    development candidate

MARSEILLE, France, Nov. 15, 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 the initiation of a new program to develop an anti-MICA
therapeutic antibody in oncology. The program, named IPH43, is the newest to
emerge from Innate Pharma's discovery platform.

MICA is a highly polymorphic ligand of the NK cell activating receptor NKG2D.
MICA is specifically expressed on several highly prevalent solid tumors
including breast, colorectal and lung. Innate Pharma has generated a panel of
high affinity antibodies recognizing all forms of MICA which is now being
tested and optimized to select the best development candidate.

Nicolai Wagtmann, CSO of Innate Pharma, said: "MICA's very clean expression
profile on tumor cells and not healthy cells makes it an exciting target for
cancer. Like with lirilumab, we successfully generated antibodies overcoming
target polymorphism, which is a major challenge and a pre-requisite for
development. We now look forward to applying our state-of-the-art
immunopharmacology and antibody-engineering platforms to further advance IPH43
towards clinical development."

Hervé Brailly, CEO of Innate Pharma, added: "Together with the recent start of
IPH4102 development, the launch of the IPH43 program illustrates Innate
Pharma's creativity and ability to spot novel targets for development of
first-in-class antibody candidates in immuno-oncology. Our discovery effort is
a key element for value creation. We generated three first-in-class candidates
brought to clinic with pharma partners and we are pleased to now progress a
second wave of these projects towards the clinic."

A poster on this program was presented at the Society for Immunotherapy of
Cancer (SITC) Annual Meeting, November 7-10, 2013, National Harbor, MD, USA:
"Targeting MICA with therapeutic antibodies for the treatment of cancer",
Saturday, November 9 from 1:00 pm - 2:00 pm and 6:15 pm - 7:15 pm, Poster 42.
The poster is available on Innate Pharma's website.
