WORCESTER, Mass., Sept. 12, 2011 (GLOBE NEWSWIRE) -- RXi Pharmaceuticals Corporation /quotes/zigman/109669/quotes/nls/rxii RXII +14.99% , a biotechnology company focused on discovering, developing and commercializing innovative therapies addressing major unmet medical needs using targeted biotherapeutics, today announced a clinical trial update on its lead program, NeuVax(TM) (E75 peptide vaccine with GM-CSF adjuvant), a cancer immunotherapy targeted for low-to-intermediate HER2 expressing breast cancer patients not eligible for trastuzamab (Herceptin(R)). RXi received official notification from the U.S. Food and Drug Administration (FDA) that the Chemistry, Manufacturing, and Controls (CMC) partial clinical hold has been lifted. RXi has satisfied all requirements specified by the FDA and has initiated a clinical trial material manufacturing plan to remain on schedule to meet the planned trial start date. NeuVax is expected to initiate its Phase 3 PRESENT (Prevention of Recurrence in Early-Stage, Node-Positive Breast Cancer with Low to Intermediate HER2 Expression with NeuVax(TM) Treatment) study in the first half of 2012 under a Special Protocol Assessment (SPA).
RXi has made other significant developments in preparation for the Phase 3 trial initiation:
-- Dr. Beth Mittendorf, Assistant Professor, Department of Surgical
Oncology, University of Texas M. D. Anderson Cancer Center has been
selected as a principal investigator for the trial. Dr. Mittendorf has
been involved in cancer vaccine research for over 10 years, has lead
numerous investigator sponsored studies, and has published extensively
in the area of breast cancer immunotherapy.
-- Conditional Institutional Review Board (IRB) approval from two key trial
sites has been received to allow for initiation of the trial, with
additional worldwide sites expected to open shortly. It is anticipated
that the trial will encompass approximately 100 trial sites in the U.S.,
Canada, and Europe.
-- RXi has engaged the Clinical Research Organization (CRO) Aptiv Solutions
to manage the trial and clinical operations are on track for PRESENT to
commence in the first half of next year.
"Our extensive progress to date, including the timely lifting of the clinical hold and significant headway with site IRBs, is testament to the team's operational excellence and its commitment to meeting program timelines," said Mark J. Ahn, President and CEO of RXi. "NeuVax is now the cornerstone for building a strong oncology pipeline as we continue to build momentum within the oncology community and look forward to presenting additional NeuVax data at key clinical meetings this Fall."
About NeuVax(TM) (E75)
RXi is also pursuing development of a cancer vaccine for breast cancer. NeuVax consists of the E75 peptide derived from HER2 combined with the immune adjuvant granulocyte macrophage colony stimulating factor (GM-CSF). Treatment with NeuVax stimulates cytotoxic (CD8+) T cells in a highly specific manner to target cells expressing any level of HER2. NeuVax is given as an intradermal injection once a month for six months, followed by a booster injection once every six months. 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(TM) Treatment) study. The Phase 3 trial is expected to commence in the first half of 2012.
According to the National Cancer Institute, over 200,000 women in the U.S. are diagnosed with breast cancer annually. Of these women, about 75% test positive for Human Epidermal growth factor Receptor 2 (IHC 1+, 2+ or 3+). Only 25% of all breast cancer patients, those with HER2 3+ disease are eligible for Herceptin(R) (trastuzumab; Roche-Genentech) which had revenues of over $5 billion in 2010. NeuVax targets the remaining 50% of HER2 positive patients (HER2 1+ and 2+) who achieve remission with current standard of care, but have no available HER2 targeted adjuvant treatment options to maintain their disease free status.
