for Dry AMD
On December 20, 2021, Lineage entered into an exclusive worldwide collaboration and license agreement with Roche and Genentech, a member of the Roche Group, for the development and commercialization of OpRegen for the treatment of ocular disorders, including advanced dry age-related macular degeneration (dry AMD) with geographic atrophy (GA) in a transaction worth up to $670 million in addition to double digit royalties. In January 2022, Lineage received a $50 million upfront payment from Genentech.
In November 2022, Genentech launched a Phase 2a, multicenter, open-label, single arm clinical study of RG6501 (OpRegen) in patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD).

OpRegen is currently being evaluated in a Phase 2a study intended to optimize subretinal surgical delivery and evaluate safety and activity in up to 60 patients. The primary objectives of the study are to evaluate (i) the proportion of patients with subretinal surgical delivery of OpRegen to target regions under the retina, and (ii) to evaluate the safety of subretinal surgical delivery of OpRegen as measured by the incidence and severity of procedure-related adverse events at 3 months following surgery. A key secondary objective is to evaluate the proportion of patients with qualitative improvement in retinal structure, as determined by Optical Coherence Tomography (SD-OCT) imaging, within 3 months following surgery.
The FDA has granted OpRegen with Fast Track Designations and, as such, is on an expedited regulatory path that includes the ability for increased interfacing with the FDA during clinical development and enhanced favorability for marketing approval.
In April 2023, data was presented at the 2023 Association for Research in Vision and Ophthalmology Annual Meeting. OpRegen Phase 1/2a clinical results support the potential for OpRegen to slow, stop or reverse disease progression in geographic atrophy secondary to age-related macular degeneration.

AMD affects more than 30 million people worldwide and approximately 1.6 million people are newly diagnosed annually in the U.S.1 It is a leading cause of vision loss in people over the age of 60 in the developed world. There are two forms of AMD: “wet AMD,” which affects only 10-15% of patients and “dry AMD,” which affects 85-90% of patients.2
