PORTLAND, Ore., Dec. 5, 2014 (GLOBE NEWSWIRE) -- Galena Biopharma, Inc. (Nasdaq:GALE), a biopharmaceutical company developing and commercializing innovative, targeted oncology treatments that address major medical needs across the full spectrum of cancer care, today announced that initial immunohistochemistry (IHC) screening data from the NeuVax™ (nelipepimut-S) Phase 3 PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax Treatment) trial will be presented at the 2014 San Antonio Breast Cancer Symposium (SABCS). The IHC screening data identifies IHC HER2 1+ and 2+ patients to support the PRESENT study and a companion diagnostic for NeuVax. The conference is taking place December 9-13, 2014 at the Henry B. Gonzalez Convention Center in San Antonio, Texas.
Poster #P2-15-02 (Abstract #1394) is entitled, "HER2 Discordant Results in Local vs. Central Testing in the Phase 3 Nelipepimut-S Trial and Implementation of Leica Bond Oracle HER2 Immunohistochemistry (IHC) System for Low and Intermediate Levels (1+, 2+) of HER2 Protein Expression as a Companion Diagnostic," and will be presented during Poster Session 2 on Thursday, December 11, 2014, from 7:30 - 9:00 a.m. in Exhibit Halls A-B.
About NeuVax™ (nelipepimut-S)
NeuVax™ (nelipepimut-S) is the immunodominant peptide derived from the extracellular domain of the HER2 protein, a well-established target for therapeutic intervention in breast carcinoma. The nelipepimut-S 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-S immune response can also generate CTLs to other immunogenic peptides through inter- and intra-antigenic epitope spreading. NeuVax is currently in an international, Phase 3 PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax Treatment) study under a Special Protocol Assessment (SPA) granted by the U.S. Food and Drug Administration (FDA). Additional information on the PRESENT trial 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).
About HER2 1+/2+ Breast Cancer
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 low to intermediate (IHC 1+/2+ or FISH < 2.0) and achieve remission with current standard of care, but have no available HER2-targeted adjuvant treatment options to maintain their disease-free status.
