BioMarin Announces Agreement With Repligen for Pre-clinical Compounds

Includes Compounds for Potential Treatment of Friedreich's Ataxia

SAN RAFAEL, Calif., Jan. 21, 2014 (GLOBE NEWSWIRE) -- BioMarin Pharmaceutical
Inc. (Nasdaq:BMRN) announced today that it has entered into an agreement to
purchase Repligen Corporation's histone deacetylase inhibitor (HDACi) library
and related intellectual property. Potential applications of the HDACi
portfolio include Friedreich's ataxia and other neurological disorders.Under
the terms of the agreement, BioMarin will provide Repligen with an upfront
payment of $2 million and potential future milestone and royalty payments for
the development, regulatory approval and commercial sale of compounds included
in this agreement. 

"This agreement represents a natural extension of BioMarin's business strategy
of acquiring promising pre-clinical programs that we can successfully develop
and commercialize for people with serious, unmet medical needs," said
Jean-Jacques Bienaime, Chief Executive Officer of BioMarin."Fredreich's
ataxia is a neurological disorder that affects tens of thousands of young
people in the developed world and we look forward to the opportunity to move a
compound into the clinic in this indication."

About Friedreich's ataxia

Friedreich's ataxia (FA) is a progressive, neurological disorder that affects
approximately 20,000 people in the United States and Europe, typically
resulting in wheelchair dependence in young adulthood and early death due to
cardiac failure. It is caused by mutations in the FXN gene, and is inherited
in an autosomal recessive manner. FXN mutations result in reduced expression
of frataxin protein, manifesting in progressive neurological and cardiac
damage. Major neurological symptoms include muscle weakness and ataxia, a loss
of balance and coordination. These symptoms typically appear between 10 and 15
years of age, but FA has been diagnosed in people from ages 2 to 50 with
earlier onset associated with a more severe course.
