Ahn, Ph.D., President and Chief Executive Officer. "Also, with the acquisition of FDA-approved Abstral, I am more excited than ever about our prospects as we further accelerate into a commercial company.

1Q, 2013 Highlights

• Lead product, NeuVax (nelipepimut-S), is enrolling patients in two key trials.

• NeuVax is the first adjuvant breast cancer vaccine to enter pivotal Phase 3 clinical trials. Galena is currently enrolling its randomized, multi-national Phase 3 trial entitled PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax™ Treatment). The study is being conducted under a Special Protocol Assessment (SPA) granted by the U.S. Food and Drug Administration (FDA), and is currently enrolling in over 125 clinical sites worldwide.
   
• A randomized, multicenter investigator-sponsored, 300 patient Phase 2b clinical trial began enrolling patients to study NeuVax in combination with Herceptin® (trastuzumab; Genentech/Roche).

• Received the 2013 Global Frost & Sullivan Award for New Product Innovation for NeuVax. In March 2013, independent research firm, Frost & Sullivan, recognized Galena Biopharma with the 2013 Global Frost & Sullivan Award for New Product Innovation. Each year, Frost & Sullivan presents this award to the company that has developed an innovative element in a product by leveraging leading-edge technologies. The award recognizes the value-added features/benefits of the product and the increased ROI it offers customers, which, in turn, increases customer acquisition and overall market penetration potential.
   
• NeuVax mechanism of action video now available at http://www.neuvax.com/how-neuvax-works/. The video can also be viewed on the www.galenabiopharma.com website.
   
• Acquired Abstral® (fentanyl) Sublingual Tablets in U.S., a Novel, Best-in-Class Treatment Approved for Breakthrough Cancer Pain. In March 2013, Galena acquired Abstral from Orexo AB (ORX.ST), an emerging specialty pharmaceutical company based in Sweden. Abstral was approved by the FDA in 2011, and is an important new treatment option for inadequately controlled breakthrough cancer pain (BTcP) in patients who are already receiving, and who are tolerant to, opioid therapy for their persistent baseline cancer pain. BTcP has been shown to affect as many as 40%-80% of cancer patients, with reported episodes of four per day and a median duration of 30 minutes. The innovative Abstral formulation delivers the analgesic power of micronized fentanyl in a sublingual tablet, which dissolves under the tongue within seconds. Abstral provides rapid relief of BTcP, predictable dosing, and is convenient and easy to use. It is the transmucosal immediate-release fentanyl (TIRF) market leader in Europe, and Galena expects to launch the drug into the $400 million U.S. market for TIRFs in in the fourth quarter of 2013.
   
• Strengthened the management team and expanded the Board of Directors with experts in oncology commercialization.

• Christopher S. Lento joined Galena as its Vice President of Sales and Commercial Operations to launch Abstral. Mr. Lento has 20 years of experience in senior level positions managing the sales, business development and operations at major healthcare companies including Genentech BioOncology, Altos Solutions, Abraxis Bioscience (acquired by Celgene Corporation), and US Oncology Network.
   
• William L. Ashton joined the Company's Board of Directors in May 2013. Mr. Ashton is a senior executive with more than twenty-eight years of experience in biotechnology and pharmaceutical leadership and management. Most recently, at Amgen, Inc., he served as Vice President of corporate and government affairs and Vice President of sales, and was directly responsible for product launches, as well as interaction with key government agencies including the Centers for Medicare and Medicaid Services.  After retiring from Amgen, Mr. Ashton joined the University of the Sciences in Philadelphia where he currently serves as Associate Provost and Senior Vice President of Strategic Business Development, Founding Dean, Mayes College of Healthcare Business and Policy, and Assistant Professor of Pharmaceutical Business.

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 (CTLs) 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 PRESENT trial is ongoing and additional information on the study can be found at www.neuvax.com. A randomized, multicenter investigator sponsored, 300 patient Phase 2b clinical trial is also enrolling patients to study NeuVax in combination with Herceptin® (trastuzumab; Genentech/Roche).

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 the approximately 50%-60% of these women who are HER2 negative (IHC 1+/2+ or FISH < 2.2) and achieve remission with current standard of care, but have no available HER2-targeted adjuvant treatment options to maintain their disease-free status.

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.
