Biogen Idec (NASDAQ: BIIB) and Samsung Bioepis today announced that through
their joint venture, Biogen Idec has exercised its right to enter into an
agreement to commercialize anti-TNF biosimilar product candidates in Europe,
including biosimilars for widely used therapies to treat conditions such as
rheumatoid arthritis and Crohn’s disease.

Under the agreement, Biogen Idec will be responsible for commercialization of
these product candidates across Europe, where there already exists a strong
market for biosimilars and a defined regulatory pathway. The agreement with
Samsung Bioepis aligns with Biogen Idec’s broader corporate objectives of
remaining focused on its core business, while leveraging its expertise in
manufacturing and specialty markets to meet the need for biosimilar therapies.

“This is a unique opportunity for us to leverage our experience in developing
and manufacturing high-quality biologics in therapeutic areas where we are
deeply focused, and provide medicines to patients where there is a significant
societal need,” said Tony Kingsley, executive vice president of global
commercial operations for Biogen Idec. “As a company that aims to make a
difference in the lives of patients with serious diseases, we are excited by
the potential to offer additional highly effective therapies in critical areas
where there is growing demand.”

“Biogen Idec has been an innovative joint venture partner in Samsung Bioepis
and now with this agreement we are excited to extend our relationship into
commercial operations,” said Christopher Hansung Ko, Ph.D., CEO of Samsung
Bioepis. “Samsung Bioepis has established a global commercialization plan for
its antibody drugs currently under development, and we believe this agreement
