The primary objective was met as shown by the absence of dose-limiting and serious toxicities, and only mild to moderate procedure related adverse events. None of the adverse events were drug related. In addition, comprehensive ocular examinations showed no indications of inflammation nor any other tolerability issues related to the treatment. Therefore, these study results show that RXI-109 was safe and well tolerated for all patients included in the three dosage groups.
Even though the primary objective of this study was to evaluate the safety and tolerability of ocular injections with RXI-109, several assessments were included to measure a potential clinical effect. These assessments included measuring the change from baseline in subretinal fibrosis lesion size, as measured by spectral domain (SD) optical coherence tomography (OCT), fundus photography and fluorescein angiography, as well as a potential effect on visual function by measuring the best corrected visual acuity (BCVA), i.e. the best vision a patient could achieve with correction (such as glasses), as measured on the standard eye charts.
RXi's Chief Development Officer, Gerrit Dispersyn, Dr. Med. Sc., commented: "This study is exciting on several levels. First, the impressive safety and tolerability of intravitreal injections of RXI-109 and the promising clinical data, support further development of this compound in retinal scarring. In addition, these positive findings also open significant avenues for the use of our platform technology in ophthalmology, with sd-rxRNA targeting other proteins for other ocular indications. Also, the results contribute to an already extensive set of data that RXI-109, by preventing the overexpression of connective tissue growth factor, can result in a positive impact in various indications where excessive fibrosis is seen. Even though this is a small study, it is encouraging that some of the summary statistics on ocular assessments performed in the study eye at the last follow-up visit, suggest a more pronounced change over baseline in the highest dose group (Cohort 3), compared to other groups."
About the RXI-109-1501 Study
RXI-109-1501 is a multi-center, multi-dose, dose escalation trial conducted in subjects with advanced neovascular or 'wet' age-related macular degeneration and accompanying subretinal fibrosis. It is the first clinical study (phase 1/2 trial) on the use of RXI-109 by ocular injections. Per the protocol, three dose levels were evaluated in a small number of subjects in order to establish safety information and to help determine the dosing regimen for a future Phase 2 study. Nine subjects were enrolled, three in each of the following dosage groups: Cohort 1 (low dose), Cohort 2 (intermediate dose), Cohort 3 (high dose). Each subject received a total of four doses of RXI-109 at one-month intervals. RXI-109 was administered by intravitreal injection in one eye only. The dosing period (3 months) was followed by a four-month observation period.
Overall Safety and Tolerability Results
About Advanced Neovascular Age-related Macular Degeneration, and Retinal Scarring
In the United States, there is no FDA-approved targeted therapy for the treatment and prevention of subretinal scarring in advanced wet age-related macular degeneration. This presents a large unmet market opportunity with approximately 11M Americans have some form of AMD, while 1.1M have NVAMD. We believe that RXI-109 is an excellent candidate to help patients with advanced NVAMD to reduce the progression of subretinal fibrosis, or as a potential prophylactic treatment for early stage NVAMD patients prior to the development of subretinal fibrosis.
About RXi's Ophthalmology Franchise
RXI-109 and RXi's sd-rxRNA technology platform are broadly protected in the United States and International regions. The Company's robust patent estate provides for multiple commercial and business development opportunities.
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 Vice President of Business Operations, Dr. James Cardia at email@example.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.
