PORTLAND, Ore., July 22, 2014 (GLOBE NEWSWIRE) -- Galena Biopharma,
Inc. (Nasdaq:GALE), a biopharmaceutical company developing and
commercializing innovative, targeted oncology treatments that address
major unmet medical needs to advance cancer care, today announced it
has entered into a definitive agreement to license the U.S. rights for
the commercial product Zuplenz(R) (ondansetron) oral soluble film. The
asset was licensed from MonoSol Rx, LLC, the developer of the oral
soluble film technology, PharmFilm(R), and manufacturer of the product.

Zuplenz was approved in 2010 by the U.S. Food and Drug Administration
(FDA) in adult patients for the prevention of highly and moderately
emetogenic chemotherapy-induced nausea and vomiting (CINV),
radiotherapy-induced nausea and vomiting (RINV), and post-operative
nausea and vomiting (PONV). Zuplenz is also approved in pediatric
patients for moderately emetogenic CINV. Nausea and vomiting are two of
the most common side-effects experienced by post-surgery patients and
patients receiving chemotherapy or radiation. It is estimated that up
to 90% of chemotherapy and up to 80% of radiotherapy patients will
experience CINV and RINV respectively.

The active pharmaceutical ingredient in Zuplenz, ondansetron, is used
to prevent nausea and vomiting caused by cancer chemotherapy, radiation
therapy, and surgery. Ondansetron belongs to a class of medications
called serotonin 5-HT3 receptor antagonists and works by blocking the
action of serotonin, a natural substance that may cause nausea and
vomiting. According to data from Wolters Kluwer, the oral 5-HT3 market
exceeds $1 billion in the U.S.

Zuplenz utilizes MonoSol Rx's proprietary PharmFilm(R) technology, an
oral soluble film that dissolves on the tongue in less than thirty
seconds. This rapidly dissolving, oral soluble film eliminates the
burden of swallowing pills during periods of emesis and in cases of
oral irritation, therefore increasing patient adherence and reducing
emergency room visits and hospitalization due to a lack of patient
compliance or the patient's inability to keep the medication down
without vomiting. Zuplenz is supplied in both 4 mg and 8 mg ondansetron
doses with a safety profile equivalent to other products in the class.

"We believe the innovative product benefits of Zuplenz, combined with
our experienced oncology sales team, will create significant
acceleration and leverage to our commercial product portfolio," said
Mark J. Ahn, Ph.D., President and Chief Executive Officer of Galena
Biopharma. "Our commercial franchise was established last year with the
acquisition of Abstral(R) for the treatment of breakthrough cancer
pain. Adding Zuplenz to our commercial portfolio enhances our offering
of supportive care products that are simple to take and provide
reliable dosing to improve the quality of life for patients suffering
from cancer or recovering from surgery and the associated
side-effects."

Galena has entered into an exclusive license and supply agreement with
MonoSol Rx, the effectiveness of which is subject to the court approval
of a settlement that MonoSol Rx has reached with a former licensee of
Zuplenz. Under the terms of the license agreement, upon effectiveness
of the license and transfer to Galena of the New Drug Application (NDA)
for Zuplenz, Galena will pay MonoSol Rx a total of $5,000,000 in cash
and stock. The license agreement also provides for fixed double-digit
royalties on net sales and pre-specified, one-time sales milestones.
Zuplenz has issued and pending U.S. patent applications with an
anticipated expiration date of 2029. Galena expects to launch Zuplenz
in early 2015.

"MonoSol Rx has established our proprietary PharmFilm technology in
multiple approved and pipeline products, including Zuplenz and
Suboxone(R). We believe Galena's established, oncology focused
commercial team understands the advantages of our PharmFilm technology
and can successfully commercialize Zuplenz in all three indications,"
concluded, A. Mark Schobel, Co-President and CEO of MonoSol Rx.

About Zuplenz(R) (ondansetron) Oral Soluble Film

Zuplenz(R) (ondansetron) Oral Soluble Film is approved by the U.S. Food
and Drug Administration (FDA). Zuplenz is approved in adult patients
for the prevention of highly and moderately emetogenic
chemotherapy-induced nausea and vomiting (CINV), radiotherapy-induced

emetogenic CINV. Nausea and vomiting are two of the most common
side-effects experienced by post-surgery patients and patients

Zuplenz utilizes the proprietary PharmFilm(R) technology as an oral

rapidly dissolving film eliminates the burden of swallowing pills
during periods of emesis and in cases of oral irritation, therefore

About Chemotherapy-, Radiation- and Post Operative-Induced Nausea and
Vomiting

It is estimated that up to 90% of patients receiving chemotherapy
experience CINV and up to 80% of patients undergoing radiotherapy will
experience RINV. For patients, CINV/RINV is among the most feared and
distressing side effects, and uncontrolled or poorly controlled
CINV/RINV can cause patients to be malnourished or dehydrated, have
electrolyte imbalances, or experience physical and mental
deterioration. In extreme cases, patients may choose to discontinue
beneficial therapy because of this side effect.

Postoperative nausea and vomiting (PONV) is one of the most commonly
occurring complications as a result of anesthesia and/or the pain
medications given during surgery. PONV results in high levels of
patient discomfort and dissatisfaction, and can result in increased
recovery room time, expanded nursing care, and potential hospital
admission--all factors that may increase total health care costs.
