Sanofi and MAB Discovery sign collaboration agreement for the

Sanofi and MAB Discovery GmbH entered into a research and license agreement in the field of monoclonal antibodies.

Neuried, Germany;  December 14, 2015:  Sanofi and MAB Discovery GmbH  announced today that  they  have  entered  into  a  research  and  license  agreement  in  the  field  of  monoclonal antibodies.  Within  the  scope  of  this  collaboration,  MAB  Discovery  will  develop  therapeutic antibodies  for  selected  targets  of  Sanofi  and  thus  support  Sanofi  in  the  development  of antibody-based  therapies.  Sanofi  will  in  return  receive  high-quality  antibodies  with  the  aim  of identifying active substances for a number of diseases that are difficult to treat. Sanofi and MAB Discovery  have  agreed  on  a  fee  for  the  research  activities.  When  specific  milestones  are achieved, the agreement provides for further performance-related payments to MAB Discovery. Financial details of the agreement were not disclosed.

"Through this agreement  with MAB Discovery we have found a strong collaboration in Germany to support us in bringing forward various antibody research projects with the help of its unique technology platform", said Prof. Dr. Jochen Maas, Head of Research & Development of Sanofi Germany.

"This  agreement  is  an  important  confirmation  for  the  quality  of  our  outstanding  research platform. MAB Discovery is a renowned antibody specialist who focuses primarily on previously refractory  diseases  with  strong  medical  needs.  Our  in-vivo  platform  based  on  a  new  highthroughput  screening  processes  could  enable  the  development  of  best-in-class  antibody therapies", said Dr. Stephan Fischer, CEO of MAB Discovery.

MAB Discovery uses its technology platform for the discovery of antibodies  in vivo, which  are based on natural immune responses in rabbits.  Subsequently,  the Company employs  state-ofthe-art technology for the cloning of  antibodies directly from  B-cells (a type of white blood cell). Applying new high-throughput screening processes,  enables  MAB Discovery  to identify  highly  active antibodies. These  identified antibodies cover a large number of different target structures (epitopes).  The  binding  of  medically  active  substances  to  endogenous  targets  is  essential  to fight diseases.  The technology employed by MAB Discovery generates a large variety of  antibodies. Of these antibodies,  those  with  the  highest  possible  biological  effectiveness  can  then  be  selected  and further  developed.  This  technology  has  already  been  used  successfully  for  targets  that  are difficult  to  address.  One  major  advantage,  among  others,  is  that  it  requires  neither  timeconsuming  optimization  of  the  target  binding,  nor  the  development  of  so-called  surrogate antibodies.
