Galena Biopharma Receives Notice of Allowance of Broad U.S. Patent for NeuVax(TM) (nelipepimut-S) Allowed Claims Cover the Use of NeuVax Alone or in Combination to Prevent Recurrence of Any Her2/neu Expressing Tumor Having a FISH Rating of Less Than About 2.0 PORTLAND, Ore., July 1, 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 the notice of allowance of a U.S. Patent for NeuVax™ (nelipepimut-S) covering the use of NeuVax alone or in combination to prevent recurrence of any HER2/neu expressing tumor having a fluorescence in situ hybridization (FISH) rating of less than about 2.0. NeuVax is a peptide immunotherapy for the prevention of cancer recurrence and is Galena's lead development agent in multiple ongoing and planned clinical trials.Once issued, the patent will expire in 2028, not including any patent term extensions. FISH is a diagnostic test used to identify patients with high levels of HER2 gene expression, or FISH greater than 2.0. These patients are eligible for existing approved HER2-directed treatments.Currently there are no approved HER2-directed therapies for patients who express lower levels of HER2, or less than 2.0 by the FISH testing scale. The patent will cover the use of NeuVax in patients with a FISH of less then about 2.0, as a stand-alone therapy or in combination with an adjuvant and/or other agents (e.g. other drugs such as Herceptin® (trastuzumab; Genentech/Roche)).Importantly, this NeuVax patent provides Galena with coverage for any tumor expressing low-to-intermediate levels of HER2. "This allowance further strengthens our broad patent estate for NeuVax, covering all tumor types expressing low-to-intermediate levels of HER2 both as a monotherapy and in combination with other agents," said Mark J. Ahn, Ph.D., President and Chief Executive Officer."Our clinical development program with NeuVax continues to grow with ongoing and planned clinical trials in breast and gastric cancers.We look forward to completing enrollment in our Phase 3 PRESENT trial this year and advancing NeuVax in other programs to prevent cancer recurrence for patients." About NeuVax™ (nelipepimut-S) NeuVax™ (nelipepimut-S) is the immunodominant nonapeptide 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 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 U.S. 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).
