OpRegen® Data Update to Be Featured at 2021 American Academy of Ophthalmology Annual Meeting in Presentation by Michael S. Ip, M.D.
CARLSBAD, Calif.--(BUSINESS WIRE)--Oct. 26, 2021--
In addition to Dr. Ip’s presentation, Lineage also intends to announce updated interim results from the Phase 1/2a study next month, which will include a minimum of 12 months of follow-up in all 24 patients treated with OpRegen, including all 12 patients treated in Cohort 4, which had better baseline vision and smaller areas of GA at baseline than earlier cohorts. OpRegen is well-positioned among product candidates in development for dry AMD as the only experimental therapy that has demonstrated an ability to halt or reverse the expansion of geographic atrophy as well as restore layers of retinal tissue in three patients to date. Specifically, outer retinal layer restoration was observed via optical coherence tomography (OCT) and was evidenced by the presence of new areas of retinal pigment epithelium (RPE) monolayer with overlying ellipsoid zone, external limiting membrane, and outer nuclear layer, all of which were not present at the time of baseline assessment. These findings are suggestive of integration of the new RPE cells with functional photoreceptors in areas that previously showed no presence of any of these cells.
OpRegen is currently being evaluated in a Phase 1/2a open-label, dose escalation safety and efficacy study of a single injection of human retinal pigment epithelium cells derived from an established pluripotent cell line and transplanted subretinally in patients with advanced dry AMD with geographic atrophy (GA). The study enrolled 24 patients into 4 cohorts. The first 3 cohorts enrolled only legally blind patients with Best Corrected Visual Acuity (BCVA) of 20/200 or worse. The fourth cohort enrolled 12 better vision patients (BCVA from 20/65 to 20/250 with smaller mean areas of GA). Cohort 4 also included patients treated with a new “thaw-and-inject” formulation of OpRegen, which can be shipped directly to sites and used immediately upon thawing, removing the complications and logistics of having to use a dose preparation facility. The primary objective of the study is to evaluate the safety and tolerability of OpRegen as assessed by the incidence and frequency of treatment emergent adverse events. Secondary objectives are to evaluate the preliminary efficacy of OpRegen treatment by assessing the changes in ophthalmological parameters measured by various methods of primary clinical relevance.

About Age-Related Macular Degeneration
AMD is an eye disease that can blur the sharp, central vision in patients and is the leading cause of vision loss in people over the age of 60. There are two forms of AMD: dry (atrophic) AMD and wet (neovascular) AMD. Dry (atrophic) AMD is the more common of the two forms, accounting for approximately 85-90% of all cases. In atrophic AMD, parts of the macula get thinner with age and accumulations of extracellular material between Bruch's membrane and the retinal pigmented epithelium, known as drusen, increase in number and volume, leading to a progressive loss of central vision, typically in both eyes. Global sales of the two leading wet AMD therapies were in excess of
