Ohr Pharmaceutical Announces New Positive Anatomic And Visual Acuity Data On OHR-102 IMPACT Study Presented At The 2014 American Academy Of Ophthalmology Scientific Meeting

Ohr Pharmaceutical, Inc.

, an ophthalmology research and development company, announced today that additional positive clinical data from the IMPACT study were presented at the 2014 American Academy of Ophthalmology (AAO) Annual Scientific Meeting, in Chicago, Illinois. The IMPACT study is a nine month phase II clinical trial evaluating Squalamine Eye Drops (OHR-102) for the treatment of the wet form of age-related macular degeneration (wet AMD). The data, presented in the AAO late breaker session by Dr. David S. Boyer on Saturday, October 18, demonstrated that the combination of OHR-102 plus Lucentis® resulted in a marked improvement in subretinal hyperreflective material (SHRM), an anatomical biomarker for wet-AMD. The regression of SHRM observed was greater in the OHR-102 combination arm compared to the Lucentis monotherapy arm. A clear relationship was demonstrated between this reduction in the SHRM biomarker and the improvements in visual acuity seen in the study. In addition, the IMPACT study demonstrated that the OHR-102 combination arm had a greater proportion of patients with total resolution of SHRM compared to the Lucentis monotherapy arm. "The interim data from the IMPACT study show that the combination of OHR-102 eye drops and Lucentis leads to better visual and anatomical outcomes in a broad wet AMD patient population," said Dr. David S. Boyer of Retina-Vitreous Associates Medical Group, Beverly Hills, and a clinical investigator in the IMPACT study. "The improvements we observed in retinal anatomy, as measured by quantitative analysis of SHRM, are important as they provide an explanation for the dramatic early and sustained visual gains achieved in these patients." The quantitative analysis of the SHRM biomarker was conducted at a large independent reading center in the U.S. Two masked readers reviewed and measured the area of SHRM on the spectral domain optical coherence tomography (OCT) scans at baseline and the final visit. Only patients with measurable SHRM at baseline were included in the analysis

Lucentis monotherapy n=27,

Lucentis monotherapy n=13). SHRM, which is visualized using OCT, is an important biomarker of neovascular AMD and is believed to represent a combination of neovascular tissue, pre-fibrotic material and other subretinal exudative and inflammatory debris. In the IMPACT study overall population, patients receiving OHR-102 combination therapy demonstrated a 75% mean reduction in the area of SHRM as compared to 56% in the Lucentis monotherapy group. In addition, 59% of patients in the OHR-102 combination arm achieved a complete resolution of SHRM versus 44% in the monotherapy arm. The mean reduction in SHRM directly correlated with the visual acuity improvements seen in each vision outcome category, with a greater reduction of SHRM in each consecutive vision gain category up to more than 90% reduction of SHRM in patients achieving ≥4 lines (≥20 letters) of visual acuity gains. "The correlation demonstrating a relationship between reduction in SHRM and increased vision outcomes are potentially groundbreaking and provide us with additional insight into the etiology of this complex neovascular disease," said Dr. Peter Kaiser, Retina Specialist at the Cole Eye Institute and Senior Vice President of Product Development at Ohr. "The increased vision improvement seen in patients with better SHRM reduction is likely caused by the normalization of retinal architecture, restoration of contact between the retinal pigment epithelium and photoreceptors, and decreased development of fibrosis. This is a good example of how multi-factor blockade in age related macular degeneration leads to disease modification not seen with anti-VEGF alone." Given that previous combination therapy trials in wet AMD focused on classic containing lesions, and SHRM is seen more often in classic choroidal neovascularization (CNV), a subgroup analysis was performed on this patient population. In these patients, even more pronounced differences in SHRM reductions were observed. Patients receiving OHR-102 combination therapy demonstrated a 74% mean reduction in the area of SHRM as compared to 43% in the Lucentis monotherapy group. In addition, 56% of patients in the OHR-102 combination arm achieved a complete resolution of SHRM versus 31% in the monotherapy arm. As with the overall analysis, the mean reduction in SHRM in these patients directly correlated with the visual acuity improvements seen in each vision outcome category, with a greater reduction of SHRM in each consecutive vision gain category up to more than 90% reduction of SHRM in patients achieving ≥4 lines (≥20 letters) of visual acuity gains. The OHR-102 patients with classic CNV also saw an improvement in visual function, with 61% of patients achieving a 20/40 vision outcome and 39% achieving a 20/32 outcome as compared to 40% and 20%, respectively, in the Lucentis monotherapy group. These levels of visual acuity represent important thresholds of visual function including the ability to perform daily tasks such as, drive a car, or read without magnification. In addition to this anatomic data, Dr. Thomas Ciulla presented important data on the IMPACT study. The two podium presentations from the AAO meeting will be available on the investor relations page of Ohr's website.
