RXi Pharmaceuticals Corporation (NASDAQ: RXII) a biotechnology company developing the next generation of immuno-oncology therapeutics based on its proprietary self-delivering RNAi (sd-rxRNA®) therapeutic platform, announced today that it was granted a patent from the United States Patent and Trademark Office (USPTO) for the methods of use of sd-rxRNAs targeting Connective Tissue Growth Factor (CTGF) for the treatment or prevention of fibrotic disorders, including skin fibrosis (USPTO Patent #: 9,963,702 B2). This patent includes RXI-109 and its use in dermal scarring, for which the safety and efficacy was shown in a recent Phase 2 clinical trial with statistically significant outcomes for improved visual appearance for RXI-109 treated scar over control. The patent is set to expire in 2031.

"Robust clinical data and strong IP are key elements to successful pharmaceutical development and commercialization," said Dr. Gerrit Dispersyn, Chief Development Officer of RXi Pharmaceuticals. He added that, "Additional data on the results of our recent clinical study with RXI-109 in dermal scarring will be presented next week at the International Investigative Dermatology Conference. These data, in combination with the granting of this patent, supports RXi's ongoing discussions with potential partners for our Dermatology Franchise, including RXI-109."
About RXi's Dermatology Franchise
RXi announced in January 2018 that it would exclusively focus on developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi therapeutic platform. As such, it is actively seeking to partner or out-license both its Dermatology and Ophthalmology Franchises.
Each of these Franchises is comprised of a number of preclinical and clinical-stage assets broadly covered by a robust intellectual property estate. To obtain more information about these assets, contact RXi's Director of Business Development, Dr. James Cardia at jcardia@rxipharma.com
About RXi Pharmaceuticals
RXi Pharmaceuticals Corporation (NASDAQ: RXII) is a biotechnology company developing the next generation of immuno-oncology therapeutics based on its self-delivering RNAi (sd-rxRNA®) therapeutic platform. The Company's discovery and research efforts are focused on developing sd-rxRNA therapeutic compounds to be used with an Adoptive Cell Transfer (ACT) approach. This process uses immune cells, such as T-lymphocytes that are isolated from the patient or retrieved from allogeneic immune cell banks, and then expanded and in some cases processed to express tumor-binding receptors. Our approach introduces a new and important step in ex-vivo processing of the immune cells where sd-rxRNA is used to eliminate the expression of immunosuppressive receptors or proteins from the therapeutic immune cells, making them less sensitive to tumor resistance mechanisms and thus improving their ability to destroy the tumor cells. Essentially, we aim to maximize the power of our sd-rxRNA therapeutic compounds by weaponizing therapeutic immune effector cells to attack cancer and ultimately provide patients battling terminal cancers with a powerful new treatment option that goes beyond current treatment modalities.
