Lineage Cell Therapeutics to Present New Data From OpRegen and Vision Restoration Programs at the Association for Research in Vision and Ophthalmology…

Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs, announced today that updated results from a Phase I/IIa study of its lead product candidate, OpRegen, a retinal pigment epithelium (RPE) cell transplant therapy currently in development for the treatment of dry age-related macular degeneration (dry AMD), have been accepted for presentation at the 2020 Association for Research in Vision and Ophthalmology (ARVO) Meeting, which will be held May 3rd through May 7th, 2020 at the Baltimore Convention Center in Baltimore, MD. The abstract presentation, entitled, "Phase I/IIa Clinical Trial of Human Embryonic Stem Cell (hESC)-Derived Retinal Pigmented Epithelium (RPE, OpRegen) Transplantation in Advanced Dry Form Age-Related Macular Degeneration (AMD): Interim Results", will be presented as part of the Gene Therapy and Stem cells Session on May 3rd, 2020 from 3:00PM to 4:45PM EDT by Christopher D. Riemann, M.D., Vitreoretinal Surgeon and Fellowship Director, Cincinnati Eye Institute and University of Cincinnati School of Medicine; Clinical Governance Board, Cincinnati Eye Institute (presentation number 865). The presentation will provide updated data from patient cohorts 1 through 4 of the clinical study and will include data on the first patients dosed with both a new subretinal delivery system as well as with a new Thaw-and-Inject (TAI) formulation of OpRegen.

"We continue to be encouraged by positive data with OpRegen for the treatment of dry AMD," stated Brian M. Culley, CEO of Lineage. "The five patients treated as part of cohort 4, which more closely match our intended patient population, have all demonstrated an increase in the number of letters they can read on an Early Treatment Diabetic Retinopathy Scale (ETDRS), having gained between 10 25 letters. Importantly, the first patient treated using both a new subretinal delivery system and our TAI formulation of OpRegen demonstrated notable improvements in vision, having gained 25 readable letters (or 5 lines) 6 months following administration of OpRegen RPE cells, as assessed by the ETDRS. This represents an improvement in visual acuity from a baseline of 20/250 to 20/100 in the treated eye. These visual acuity measurements are meaningful and can translate into quality of life enhancements to things like reading, driving, or avoiding accidents. With the opening of two leading ophthalmology research centers as clinical sites for our study, we are focused on rapid enrollment so that our clinical update at ARVO can be as mature and informative as possible. Our objective is to combine the best cells, the best production process and the best delivery system, which we believe will position us as the front-runner in the race to address the unmet opportunity in the potential billion-dollar dry AMD market."

In addition, Lineage will present new preclinical results from its Vision Restoration Program, a proprietary program based on the ability to generate 3-dimensional human retinal tissue derived from pluripotent cells. Lineages 3-dimensional retinal tissue technology may address the unmet need of implementing a retinal tissue restoration strategy to address a wide range of severe retinal degenerative conditions including retinitis pigmentosa and advanced forms of AMD. In 2017 and 2019, the Small Business Innovation Research program of the National Institutes of Health awarded Lineage grants of close to $2.3 million to further develop this innovative, next generation vision restoration program.

- The poster presentation, entitled, "Transplantation of organoid-derived human retinal tissue in to the subretinal space of CrxRdy/+ cats)," will be presented as part of the Animal models for visual disease and restoration Session on May 4th, 2020 4:00PM to 5:45PM EDT in Session Number 291 by Igor Nasonkin, Ph.D., Principal Investigator, Director of Research & Development at Lineage (Poster board Number: 2253 - B0162).

- The poster presentation, entitled, " Intraocular biocompatibility of Hystem hydrogel for delivery of pharmaceutical agents and cells," will be presented as part of the Stem cells and organoids: Technical advances Session on May 5th, 2020 between 8:45AM to 10:30AM EDT in Session Number 332 by our collaborator Randolph D. Glickman, Ph.D., Professor of Ophthalmology, UT Health San Antonio (Poster board Number: # A0247).

About Lineage Cell Therapeutics, Inc.

Lineage Cell Therapeutics is a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs. Lineages programs are based on its robust proprietary cell-based therapy platform and associated in-house development and manufacturing capabilities. With this platform Lineage develops and manufactures specialized, terminally-differentiated human cells from its pluripotent and progenitor cell starting materials. These differentiated cells are developed either to replace or support cells that are dysfunctional or absent due to degenerative disease or traumatic injury or administered as a means of helping the body mount an effective immune response to cancer. Lineages clinical programs are in markets with billion dollar opportunities and include (i) OpRegen, a retinal pigment epithelium transplant therapy in Phase I/IIa development for the treatment of dry age-related macular degeneration, a leading cause of blindness in the developed world; (ii) OPC1, an oligodendrocyte progenitor cell therapy in Phase I/IIa development for the treatment of acute spinal cord injuries; and (iii) VAC2, an allogeneic cancer immunotherapy of antigen-presenting dendritic cells currently in Phase I development for the treatment of non-small cell lung cancer. Lineage is also evaluating potential partnership opportunities for Renevia, a facial aesthetics product that was recently granted a Conformit Europenne (CE) Mark.
