Data Reinforce Efficacy of Voretigene Neparvovec in RPE65-Mediated IRD
Spark Therapeutics announced that Albert M. Maguire, MD, professor of ophthalmology at the Perelman School of Medicine of the University of Pennsylvania, presented one-year efficacy data from the crossover group and two-year durability data from the original intervention group for the Phase III trial of voretigene neparvovec (formerly SPK-RPE65) during Retina Subspecialty Day at the American Academy of Ophthalmology annual meeting in Chicago. Dr. Maguire is the study's principal investigator. Voretigene neparvovec, an investigational gene therapy for inherited retinal disease caused by mutations in the RPE65 gene, has received both breakthrough therapy and orphan product designations from the U.S. Food and Drug Administration, as well as orphan product designations from the European Medicines Agency. Results from the ongoing Phase III trial of voretigene neparvovec showed that 93 percent of subjects, including those in the original control group who crossed over to receive intervention, demonstrated a gain in functional vision, and maintained that improvement over one year following the procedure, Dr. Maguire reported at the meeting. Additionally, he said the original intervention group sustained its year-one improvement at year two. He said further the data bolsters the growing dataset supporting voretigene neparvovec.

Eye Test May Detect Parkinson’s Before Symptoms Appear
A new noninvasive eye test could detect Parkinson’s disease before symptom onset, according to research in rats led by scientists at University College London Institute of Ophthalmology. Researchers discovered a new way to observe changes in the retina in advance of brain changes and symptoms onset caused by the Parkinson’s. Using ophthalmic instruments routinely used in eye clinics, the scientists used a new imaging technique to observe retinal changes at an early stage. This method, published in Acta Neuropathologica Communications, would enable earlier diagnosis of Parkinson’s and monitoring of patient response to treatment. The technique—for which one of the researchers holds the patent—has been tested in humans for glaucoma, and trials are expected to start for Alzheimer’s. Following the observation of retinal changes in the experimental model, researchers treated animals with a newly formulated version of the anti-diabetic drug Rosiglitazone, which helps to protect nerve cells. After using the drug, evidence of reduced retina cell death, as well as a protective effect on the brain, was observed, suggesting the drug could have potential as a treatment for Parkinson’s disease.

Abicipar Pegol PALM Study Phase II Data Presented at AAO Annual Meeting
Molecular Partners AG announced that Tarek S. Hassan, MD, professor of ophthalmology at Oakland University William Beaumont School of Medicine, and senior partner and director of the vitreoretinal fellowship training program at Associated Retinal Consultants in Royal Oak, Mich., presented data from PALM, a multicenter, double-masked, Phase II clinical trial evaluating Abicipar Pegol for diabetic macular edema, at the American Academy of Ophthalmology annual meeting in Chicago. A total of 151 individuals with DME (best-corrected visual acuity ≤75 and ≥24 letters) were enrolled. The efficacy of abicipar was demonstrated in all treatment groups. Abicipar 2 mg (q8 weeks and q12 weeks, following three monthly loading doses) demonstrated functional (BCVA) and anatomical (central retinal thickness) effects comparable with monthly ranibizumab, and with fewer injections over a 28-week period. The most common ocular adverse events were vitreous floaters and conjunctival hemorrhage in the abicipar arms. Intraocular inflammation occurred in seven, five and four individuals treated with abicipar 1 q8, 2 q8 and 2 q12 groups, respectively, and no individuals treated with ranibizumab. The events were mostly mild to moderate in severity, and resolved with treatment. Allergan is currently enrolling patients in a Phase III trial for AMD using an updated formulation of abicipar, and topline results are expected in 2018. Molecular Partners exclusively licensed abicipar to Allergan in May 2011. Read more.

Co-formulated Aflibercept Shows No Benefit Over Aflibercept Alone for nAMD
Regeneron Pharmaceuticals announced topline results from the Phase II CAPELLA study evaluating aflibercept co-formulated with rinucumab, an anti-platelet-derived growth factor receptor beta antibody, in individuals with neovascular age-related macular degeneration. The combination therapy did not demonstrate an improvement in best-corrected visual acuity compared with intravitreal aflibercept injection monotherapy at 12 weeks, the primary endpoint of the study. At 12 weeks, individuals in both combination aflibercept/rinucumab groups showed a 5.8-letter improvement in BCVA. Those treated with aflibercept alone showed a 7.5-letter improvement in BCVA. Eylea results in this study were consistent with the efficacy and safety seen in the drug’s Phase III pivotal studies in wet AMD. The efficacy results in the CAPELLA trial were consistent across all choroidal neovascularization subtypes. Adding rinucumab to aflibercept showed no benefit on anatomic endpoints including reduction in retinal thickness or in resolution of subretinal hyperreflective material. Read more.

UAB Researchers Look at DR Screening Follow-up Adherence
University of Alabama at Birmingham researchers Cynthia Owsley, PhD, the Nathan E. Miles Chair of Ophthalmology in the UAB Department of Ophthalmology, and UAB School of Medicine student Zachary Keenum are trying to determine the extent that county clinic patients with diabetes in a diabetic retinopathy screening program adhere to the timetable of recommended follow-up eye exams. The American Diabetes Association and the American Academy of Ophthalmology Retina Panel recommend annual dilated eye examination for people with diabetes, beginning five years after diagnosis for type 1 diabetes and at the time of diagnosis, and annually thereafter for type 2 diabetes. The study found that an estimated two-thirds of individuals with self-reported diabetes receive an annual dilated eye exam, and those annual use estimates were even lower among African-Americans. The study, published in JAMA Ophthalmology, was funded by the Centers for Disease Control and Prevention. Read more.

Opthea's Phase I Data Presented at EURETINA Congress
Opthea Limited announced that data from its Phase I clinical trial of OPT-302 was presented at the European Society of Retina Specialists Congress on Sept. 10, in Copenhagen, Denmark. OPT-302 is Opthea's lead program, a novel VEGF-C/D “Trap” therapy for wet age-related macular degeneration. The presentation provided an overview of the scientific rationale for targeting VEGF-C/D for the treatment of wet AMD along with recently announced positive data from Opthea's ongoing first-in-human clinical trial of OPT-302. The initial results have demonstrated safety and tolerability of OPT-302 administered as a monotherapy and in combination with standard-of-care Lucentis, and may suggest that combined administration of OPT-302 plus Lucentis could lead to improved clinical outcomes over Lucentis alone.

Study Demonstrates Gene Delivery Feasibility for Inherited Retinal Degeneration
Researchers have demonstrated the ability to deliver a fully functional copy of the CLN3 gene to stem cells of patients with juvenile neuronal ceroid lipofuscinoses (NCL), one of a group of inherited neurodegenerative disease in which a mutation in the CLN3 gene causes early-onset, severe central vision loss. The gene therapy restored production of CLN3 protein in the stem cell-derived retinal neurons, as described in an article in Human Gene Therapy. Researchers from University of Iowa, Iowa City, described the gene augmentation method they developed using an adeno-associated virus vector carrying the full-length coding sequence of human CLN3 to deliver the gene to induced pluripotent stem cells derived from individuals' fibroblasts. The researchers also demonstrated the safety of AAV2-CLN3, which reportedly produced no toxicity when injected into the retinas of mice. They proposed that their findings support initiation of a clinical trial using AAV-mediated gene augmentation to treat children with CLN3-associated retinal degeneration. Read more.
