(Nasdaq:GALE), a biotechnology company focused on developing innovative,
targeted oncology treatments, today announced it has signed an agreement with
a subsidiary of Teva Pharmaceutical Industries Limited for the
commercialization of NeuVax™ (nelipepimut-S or E75) in Israel.

"This agreement is the first piece of our global commercialization strategy,"
said Mark Ahn, Ph.D., President and Chief Executive Officer, Galena
Biopharma."Teva is a world-class pharmaceutical company and a major
pharmaceutical company in Israel.We look forward to their valuable financial
support towards our development goals in Israel, as well as market leadership
for NeuVax commercialization in the region."

NeuVax Phase 3 PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive
Breast Cancer with Low-to-Intermediate HER2 Expression with NeuVax Treatment)

"We are embarking on a very exciting and innovative venue for the adjuvant
treatment of early breast cancer. In this study we are boosting the body's
natural immune system to deal with possible residual cancer cells still
present.The biological reasoning behind this treatment is sound. We hope that
the results of this large randomized study will confirm the encouraging
results seen in earlier studies using this agent,"commented Dr. Noa Efrat
(Ben-Baruch), M.D., Head Department of Oncology at Kaplan Medical Center, and
an investigator for the trial in Israel.

About NeuVax (nelipepimut-S)

NeuVax™ (nelipepimut-S) is the immmunodominant nonapeptide derived from the
extracellular domain of the HER2 protein, a well-established target for
therapeutic intervention in breast carcinoma.The nelipepimut sequence
stimulates specific CD8+ cytotoxic T lymphocytes (CTL) following binding to
HLA-A2/A3 molecules on antigen presenting cells (APC).These activated
specific CTLs recognize, neutralize and destroy through cell lysis HER2
expressing cancer cells, including occult cancer cells and micrometastatic
foci.The nelipepimut immune response can also generate CTLs to other
immunogenic peptides through inter- and intra-antigenic epitope
spreading.Based on a successful Phase 2 trial, which achieved its primary
endpoint of disease-free survival (DFS), the Food and Drug Administration
(FDA) granted NeuVax™ a Special Protocol Assessment (SPA) for its Phase 3
PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer
with Low to Intermediate HER2 Expression with NeuVax Treatment) study.The
Phase 3 trial is ongoing and additional information on the study can be found

According to the National Cancer Institute, over 230,000 women in the U.S. are
diagnosed with breast cancer annually.Of these women, only about 25% are HER2
positive (IHC 3+). NeuVax targets approximately 50-60% of HER2-negative
patients (IHC 1+/2+ or FISH <2.2) who achieve remission with current standard
of care, but have no available HER2-targeted adjuvant treatment options to
maintain their disease-free status.
