- NeuVax™ is slated to commence Phase III clinical trials in low-to-intermediate HER2+ breast cancer patients, not eligible for Herceptin®, in 1H 2012
- RXi’s first self-delivering RNAi product candidate, RXI-109 which targets CTGF (connective tissue growth factor), scheduled to commence human clinical trials for anti-scarring in planned surgeries in early 2012
WORCESTER, Mass.--(BUSINESS WIRE)-- RXi Pharmaceuticals Corporation (Nasdaq: RXII), a biotechnology company focused on discovering, developing and commercializing innovative therapies addressing major unmet medical needs using RNA-targeted and immunotherapy technologies, today announced the completion of its previously announced acquisition of Apthera, Inc.
The acquisition provides RXi with a late stage product candidate, NeuVax™, a peptide-based immunotherapy for low-to-intermediate HER2+ breast cancer, patients who are not eligible for Herceptin® RXi has targeted NeuVax to enter Phase III clinical trials in the first half of 2012. The Company’s first self-delivering RNAi product, RXI-109 for anti-scarring in planned surgeries, remains on track for an investigational new drug (IND) application filing this year.
Under the terms of the acquisition agreement, Apthera stockholders will initially receive approximately 4.8 million shares of RXi’s common stock. Apthera’s stockholders will also be entitled to contingent payments based on the achievement of certain development and commercial milestones relating to Apthera’s NeuVax™ product candidate.
“NeuVax and RXI-109 significantly advance RXi into a product development company with novel therapeutics addressing large unmet medical needs,” said Mark J. Ahn, PhD, President and Chief Executive Officer of RXi Pharmaceuticals. “We believe we have the people, pipeline and resources to realize the promise of our innovative products for patients and shareholders.”
An audiocast presentation including an RXi corporate overview of the Apthera acquisition and cancer immunotherapy treatment featuring Dr. Mark Ahn and NeuVax developer Dr. George Peoples will be available from the “Investor Relations” section of the Company's website, www.rxipharma.com.
About NeuVax™ (E75)
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 II 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 a Phase III clinical trial in adjuvant therapy of women with low-to-intermediate HER2+ status.
According to the National Cancer Institute, over 200,000 women are diagnosed with breast cancer annually in the US alone in 2010. 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+ breast cancer patients are eligible for Herceptin® (trastuzumab; Roche-Genentech) which had revenues of over $5 billion in 2010. NeuVax targets the remaining 50% of HER2 positive patients, those who are HER2+ 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.
About RXI-109
RXi Pharmaceuticals has initiated development of clinical candidate RXI-109, a self-delivering RNAi compound (sd-rxRNATM) for the reduction of dermal scarring in planned surgeries. RXI-109 is designed to reduce the expression of CTGF (connective tissue growth factor) a critical regulator of several biological pathways involved in fibrosis, including scar formation in the skin. RXi is beginning manufacturing activities with an experienced cGMP oligonucleotide manufacturer to support its IND enabling toxicology program, and is preparing a pre-IND package for submission to the FDA. Pending FDA review, the company intends to use an innovative clinical trial design to study safety and tolerability as well as initial efficacy in its first clinical trial targeted for 2012.
