CAMBRIDGE, Mass. -- January 9, 2014

Sarepta Therapeutics, Inc. (NASDAQ: SRPT), a developer of innovative RNA-based
therapeutics, today announced Arthur "Art" Krieg, M.D., has been named senior
vice president and chief scientific officer. In this role, Dr. Krieg will lead
the company’s drug discovery and early-stage research activities.

“We are excited to welcome Art to Sarepta as we advance the field of RNA
medicine with our proprietary technologies,” said Chris Garabedian, president
and chief executive officer of Sarepta Therapeutics. “With more than two
decades of experience in oligonucleotide drug development, Art’s outstanding
scientific leadership will support the advancement of our exon skipping
franchise in Duchenne muscular dystrophy as well as the expansion of our
product pipeline.”

Dr. Krieg joins Sarepta from RaNA Therapeutics, where he served as chief
executive officer since he co-founded the company in 2011. Prior to RaNA, he
was chief scientific officer of Pfizer’s Oligonucleotide Therapeutics Unit
from 2008 to 2011. Previously, he was the chief scientific officer, executive
vice president of research and development, and co-founder of Coley
Pharmaceutical Group, prior to its acquisition by Pfizer in 2008.

Dr. Krieg discovered the immune stimulatory CpG DNA motif in 1994, which led
to a new approach to immunotherapy and vaccine adjuvants. Based on this
technology, he co-founded Coley Pharmaceutical Group in 1997, discovering and
taking four novel oligonucleotides into clinical development. He was a
co-founder of the first antisense journal, Oligonucleotides, which he edited
for 16 years, and he co-founded the Oligonucleotide Therapeutic Society. He is
a director of Cytos Biotechnology and a member of the scientific advisory
boards of RaNA and Mirna Therapeutics. Dr. Krieg received his doctor of
medicine degree from Washington University, completed a residency in internal
medicine at the University of Minnesota and a rheumatology fellowship at the

the University of Iowa, becoming professor of internal medicine in the
Division of Rheumatology. He has published more than 240 scientific papers and
is co-inventor on 47 issued U.S. patents covering oligonucleotide

“The recent resurgence in the field of RNA therapeutics has been due in part
to the excitement around Sarepta’s exon skipping therapies and their potential
for patients with Duchenne,” said Dr. Krieg. “I look forward to joining the
Sarepta team as we seek to advance these programs and realize the full
potential of Sarepta’s technologies to address other serious and
life-threatening diseases.”

of Directors of Sarepta approved an inducement stock option grant to Dr. Krieg
