LAKE OSWEGO, Ore., May 9, 2013 (GLOBE NEWSWIRE) -- Galena Biopharma, Inc.
(Nasdaq:GALE), a biopharmaceutical company developing innovative, targeted
oncology treatments that address major unmet medical needs to advance cancer
care, presented information on the development of a Transmucosal Immediate
Release Fentanyl (TIRF) REMS program at the American Pain Society 32^nd Annual
Scientific Meeting.The event is being held May 8-11, 2013 at the Ernest N.
Morial Convention Center in New Orleans, Louisiana.

The poster presentation entitled: "Development of a Federally Mandated Risk
Evaluation and Mitigation Strategy (REMS) for Transmucosal Immediate-Release
Fentanyl Products" describes the development and implementation of the now
fully implemented TIRF REMS program for this important class of drug.The
poster concluded that the TIRF REMS program is an important step toward the
Food and Drug Administration Amendments Act (FDAAA) goals to reduce misuse,
abuse, addiction, overdose, and medication-related errors.The shared TIRF
REMS program streamlines the process to safely provide appropriate patients
with various forms of TIRF medications, and points out that the goals of the
TIRF REMS program need to be balanced against the potential for untreated or
poorly treated pain.The complex nature of these goals requires collaboration
amongst prescribers, pharmacies, distributors, and patients to achieve optimal
success.

"Abstral is a significant advance for patients with breakthrough cancer pain
and the TIRF REMS program is an essential element to prescribing Abstral® to
ensure that patients are safely and effectively treated," stated Mark J. Ahn,
Ph.D., Galena's President and Chief Executive Officer."Abstral's sublingual
TIRF REMS program served as a model for the current shared TIRF REMS, and we
look forward to launching our product in the U.S. this year."

The presentation also concluded that the shared TIRF REMS program aims to
minimize risk by limiting the dispensing of medication to appropriate
patients, preventing inappropriate conversion between fentanyl products,
avoiding accidental exposure, and providing education on medication-related
risks.

"The TIRF REMS program provides my practice with the ability to choose the
appropriate product based on my patient's needs, and Abstral is an essential
drug as part of this arsenal to effectively treat my cancer patients with
breakthrough pain," added Srinivas R. Nalamachu, M.D., International Clinical
Research Institute, Overland Park, Kansas.

About Abstral® (fentanyl) Sublingual Tablets

Abstral® (fentanyl) Sublingual Tablets are an important new treatment option
for inadequately controlled breakthrough cancer pain (BTcP) which impact
40%-80% of cancer patients. Abstral is approved by the FDA, and is a
sublingual (under the tongue) fentanyl tablet indicated only for the
management of breakthrough pain in patients with cancer, 18 years of age and
older, who are already receiving, and who are tolerant to, opioid therapy for
their persistent baseline cancer pain. The innovative Abstral formulation
delivers the analgesic power and increased bioavailability of micronized
fentanyl in a more convenient sublingual tablet which rapidly dissolves under
the tongue in seconds, provides rapid relief of breakthrough pain in minutes,
and matches the duration of the entire pain episode.
