EMD Serono Announces Appeals Court Decision

  EMD Serono Announces Appeals Court Decision

Business Wire

ROCKLAND, Mass. -- April 15, 2013

A Pennsylvania appellate court recently decided that the collaboration
agreement that EMD Serono Inc., a subsidiary of Merck KGaA, Darmstadt,
Germany, and Pfizer Inc. entered into in July 2002 for the co-promotion of the
multiple sclerosis treatment Rebif^® (interferon beta-1a) extends until
December 31, 2015.

EMD Serono, which developed Rebif, had contended that the collaboration should
end on December 31, 2013, based on the provisions of the agreement governing
extension of the term, and had filed a complaint seeking a court declaration
to that end. A lower court ruled that the agreement extends through 2015 and
the appellate court affirmed that decision. EMD Serono has asked the appellate
court to reconsider its ruling. Unless the court grants the request on or
before June 7, it will be deemed denied.

EMD Serono remains committed to the success of Rebif and its efforts to
promote Rebif. The decision will have no impact on patients or supply of Rebif
and does not change the company’s Rebif business plans and growth prospects in
the US.
