MARLBOROUGH, Mass., April 28, 2016 /PRNewswire/ -- RXi Pharmaceuticals Corporation (NASDAQ: RXII), a clinical-stage RNAi company developing innovative therapeutics in dermatology and ophthalmology that address significant unmet medical needs, announced today that the Company has generated new data demonstrating corneal delivery of a fluorescent analog of RXI-109, the Company’s most advanced clinical compound, currently in human clinical trials for dermal scarring and subretinal fibrosis associated with late stage AMD. Topical administration to the eye of the Company’s novel self-delivering RNAi (sd-rxRNA®) technology formulated in a gel resulted in delivery throughout the cornea in the presence of a corneal wound in vivo.

“These findings further highlight the utility of our sd-rxRNA platform and provide evidence of the potential development of topical oligonucleotide based therapeutics for front of the eye indications,” said Pamela Pavco, Ph.D., RXi’s Chief Development Officer. She further added, “We know that corneal wounds can lead to scar formation and impaired vision. These data broaden the market potential for RXI-109 and open new avenues for collaboration.”
As previously released, this data will be presented at ARVO on Sunday, May 1, 2016 and the poster will be available under the “Investors Presentations & Posters” section of the Company’s website, www.rxipharma.com.
About RXi’s Proprietary Self-delivering RNAi (sd-rxRNA®) Platform
Building on the pioneering work of Dr. Craig Mello, Nobel Laureate and RXi’s Scientific Advisory Board Chairman, scientists at RXi developed novel sd-rxRNA compounds where drug-like properties are built into the RNAi compound itself. These proprietary compounds are novel RNAi compounds with enhanced properties for therapeutic use including: efficient spontaneous cellular uptake, stability, reduced potential for immune stimulation, and potent, long-lasting intracellular activity. All cell types tested (primary, neuronal and non-adherent) internalize sd-rxRNA compounds uniformly and efficiently, resulting in potent and long lasting silencing. Efficient cellular uptake is observed both in vitro and in vivo, including into tissues such as skin and retina following local administration, and liver following systemic delivery. RXI-109, an sd-rxRNA compound is designed to silence connective tissue growth factor (CTGF), which plays a key role in tissue regeneration and repair. RXI-109 is currently being evaluated in two clinical trials. A Phase 1/2 clinical study, RXI-109-1501, is underway to evaluate the safety and clinical activity of RXI-109 to prevent the progression of retinal scarring, a harmful component of numerous retinal diseases. In addition, a Phase 2 clinical trial, RXI-109-1402, is currently evaluating RXI-109 as a treatment to reduce the recurrence of hypertrophic scars following scar revision surgery. Over 100 subjects have been treated with RXI-109 by intradermal injection in all trials to date. Multiple intradermal injections were well tolerated at all dose levels. RXI-109 was shown to cause a dose-dependent silencing of CTGF messenger RNA and protein levels in the treated areas of the skin compared to placebo and preliminary results from Phase 2a studies indicate a clinical effect on scar appearance.
