CARLSBAD, Calif., Oct. 23, 2012 /PRNewswire/ -- Isis Pharmaceuticals, Inc.
(NASDAQ: ISIS) announced today that it will receive $1.1 million from Alnylam
Pharmaceuticals, Inc. (NASDAQ: ALNY) as its portion of the upfront fees in
Alnylam's recently announced collaboration with Genzyme. In addition, Isis
has the potential to receive royalty payments and a portion of future
milestone payments. Already this year, Isis has earned $2.7 million from
Alnylam as a result of Alnylam's licenses that were supported by Isis'
patents, further emphasizing the value of Isis' innovation and the leadership
role Isis has played in the field of RNA-based technology.

"We have a broad and valuable patent estate built upon our innovations and
discoveries related to RNA-based technologies that provides us with extensive
protection for our drugs and our technologies. Our business strategy
maximizes the value of these innovations by granting partners access to our
technology for uses that are outside our key areas of focus. Using this
strategy, we have been able to generate more than $400 million from the sale
and licensing of our intellectual property," said B. Lynne Parshall, chief
operating officer and chief financial officer at Isis.

Isis is the leading company in RNA-based technology and owns or controls more
than 1,500 issued patents. As such, Isis holds patents for numerous
applications of antisense technology, including RNAi, and for novel targets,
such as microRNAs being developed by Regulus, which was co-founded by Isis and
Alnylam. In 2004, Isis and Alnylam entered into a strategic relationship in
which Alnylam obtained an exclusive license to Isis' intellectual property for
double-stranded oligonucleotide therapeutics that mediate RNAi. In return,
Isis received an upfront payment and financial participation in future
transactions supported by Isis' patents.
