Dr. Karen Bulock, Vice President of Research at RXi Pharmaceuticals said, "Immunotherapy treatments have shown significant promise in extending the lifespan of previously untreatable cancer patients. We are excited to work with the extraordinary scientific leaders at the CCIT to evaluate the advantages of our therapeutic sd-rxRNA compounds in various cancer models." She further added that, "This research collaboration, in combination with other collaborations we have announced, are going to be key cornerstones in our efforts to translate positive results into a clinical setting which we hope to achieve within the next 12-18 months."

Professor and Director at CCIT, Inge Marie Svane, MD, Ph.D., said that, "Over the course of the last few years, the CCIT has carried out numerous clinical trials based on a direct translation of the discoveries from the laboratory. We are excited to test the potential of RXi's innovative self-delivering RNAi technology platform to potentiate TILs for ACT."

About RXi Pharmaceuticals

RXi Pharmaceuticals Corporation (NASDAQ: RXII) is a clinical-stage company developing innovative therapeutics that address significant unmet medical needs. Building on the pioneering discovery of RNAi, scientists at RXi have harnessed the naturally occurring RNAi process which can be used to "silence" or down-regulate the expression of a specific gene that may be overexpressed in a disease condition. RXi developed a robust RNAi therapeutic platform, including self-delivering RNA (sd-rxRNA®) compounds, that have the ability to highly selectively block the expression of any target in the genome, thus providing applicability to many therapeutic areas. Our current programs include dermatology, ophthalmology, and cell-based immunotherapy. RXi's extensive patent portfolio provides for multiple product and business development opportunities across a broad spectrum of therapeutic areas, and we actively pursue research collaborations, partnering and out-licensing opportunities with academia and pharmaceutical companies.
