SAN RAMON, Calif., June 29, 2016 (GLOBE NEWSWIRE) -- Galena Biopharma, Inc. (NASDAQ:GALE), a biopharmaceutical company committed to the development and commercialization of targeted oncology therapeutics that address major unmet medical needs, today announced the recommendation from the Independent Data Monitoring Committee (IDMC) on the interim analysis for Galena’s 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) clinical trial. On June 27, 2016, the IDMC recommended that the PRESENT trial be stopped due to futility. The letter is attached to the Form 8-K filed today and available on the Company’s website. This planned safety and futility interim analysis was triggered after 70 qualifying disease free survival (DFS) events were reached, and a total of 71 events were reviewed by the IDMC.
“We are extremely disappointed with the outcome of the PRESENT futility analysis,” said Mark W. Schwartz, Ph.D., President and Chief Executive Officer. “On behalf of our entire company, I would like to thank all of the courageous patients and their families, investigators, study staff and independent committees who participated in the PRESENT study. To date, the trial has not been un-blinded other than by the IDMC, and we need to evaluate the data. We expect to host a conference call next week to provide a preliminary review of the PRESENT trial and an update on all of our immunotherapy and hematology clinical development programs.”
PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax Treatment) is an international, Phase 3 study to evaluate NeuVax plus GM-CSF versus placebo plus GM-CSF to prevent cancer recurrence. The trial is being run under a Special Protocol Assessment (SPA) granted by the U.S. Food and Drug Administration (FDA). PRESENT is targeting patients who are node positive, HER2 IHC 1+/2+, and HLA A2+ and/or A3+. The study is double blind, randomized 1:1, and is stratified by stage, type of surgery, hormone receptor status, and menopausal status. Galena enrolled a total of 758 patients, and the primary endpoint for the trial was disease free survival (DFS) upon reaching 141 events with 3 years minimum follow-up. Additional information on the trial can be found here and at clinicaltrials.gov identifier: NCT01479244.
About NeuVax™ (nelipepimut-S)
NeuVax™ (nelipepimut-S) is a first-in-class, HER2-directed cancer immunotherapy under evaluation to prevent breast cancer recurrence after standard of care treatment in the adjuvant setting. It 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 specific HLA 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. In clinical studies, NeuVax is combined with recombinant granulocyte macrophage-colony stimulating factor (GM-CSF).
In addition to PRESENT, Galena has two breast cancer studies ongoing with NeuVax in combination with trastuzumab (Herceptin®; Genentech/Roche): a Phase 2b trial in node positive and triple negative HER2 IHC 1+/2+ (clinicaltrials.gov identifier: NCT01570036); and, a Phase 2 trial in high risk, node positive or negative HER2 IHC 3+ patients (clinicaltrials.gov identifier: NCT02297698). Phase 2 clinical trials with NeuVax are also planned in patients with ductal carcinoma in situ (DCIS), and in patients with gastric cancer.
