Lineage Cell Therapeutics and AgeX Therapeutics Announce Expansion of Agreement Related to ESI Clinical-Grade Pluripotent Stem Cell Lines for Therapeutic Purposes

• Lineage Acquires Exclusivity for ESI Cell Lines in Spinal Cord Injury and Certain Oncology Indications
• AgeX Secures Independence to License out ESI Cell Lines as Part of its Collaboration and Licensing Model

CARLSBAD, Calif. & ALAMEDA, Calif.–(BUSINESS WIRE)–$LCTX #AMD—Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs, ES Cell International Pte Ltd. (ESI), a subsidiary of Lineage, and AgeX Therapeutics, Inc. (“AgeX”: NYSE American: AGE), a company focused on developing and commercializing innovative therapeutics for human aging, today announced the broadening of their collaborative relationship with regard to ESI stem cell lines. ESI cell lines are current Good Manufacturing Practice (cGMP)-compatible, registered with the National Institutes of Health (NIH), and widely studied as a potential source for the industrial-scale manufacture of any cell type in the human body. Neither party made or received any cash payments in connection with this arrangement.

“Both Lineage and AgeX are pioneering important aspects of regenerative medicine. Working together, we have amended our agreement regarding ESI cell lines derived under cGMP to be optimal for the business needs of each company,” stated Brian M. Culley, Lineage’s CEO. “In particular, Lineage has acquired exclusivity for the use of ESI cell lines in spinal cord injury and certain oncology indications. On the other hand, AgeX has gained greater flexibility and independence to support its efforts toward licensing certain technologies and cell lines to third parties. With this step complete, we next intend to explore additional opportunities to collaborate with AgeX on promising tissue regenerating projects.”

The ESI cell lines are recognized for being the first clinical-grade human pluripotent stem cell lines created under cGMP as described in the publication Cell Stem Cell (2007;1:490-4). It may become possible to generate potentially limitless quantities of all the cell types of the human body from these master cell banks with a wide array of potential therapeutic applications. (Read more…) These cell lines are listed on the NIH Stem Cell Registry and are among the best characterized and documented stem cell lines available globally. Importantly, ESI cells are among only a few pluripotent stem cell lines from which a derived cell therapy product candidate has been granted FDA investigational new drug (IND) clearance to commence human studies.

“Key to the creation of shareholder value is the placement of these important assets in the hands of collaborators to advance the development of a vast number of regenerative therapies,” said Michael West, Ph.D., AgeX’s CEO. “Our collaborative relationship with Lineage led to this streamlined process that may facilitate the commercialization of these applications to the benefit of shareholders of each company. Since the beginning of the year, AgeX has entered into new research and commercial arrangements utilizing an array of its technology platforms, such as UniverCyte^TM for the engineering of universally transplantable cells, PureStem^® for the manufacture and derivation of cells, and an ESI cell line as source material for deriving cellular therapeutics.”

About Lineage Cell Therapeutics, Inc.

Lineage Cell Therapeutics is a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs. Lineage’s 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 to either 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. Lineage’s clinical programs are in markets with billion dollar opportunities and include three allogeneic (“off-the-shelf”) product candidates: (i) OpRegen^®, a retinal pigment epithelium transplant therapy in Phase 1/2a 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 1/2a development for the treatment of acute spinal cord injuries; and (iii) VAC, an allogeneic dendritic cell therapy platform for immuno-oncology and infectious disease, currently in clinical development for the treatment of non-small cell lung cancer and in preclinical development for additional cancers and as a vaccine against infectious diseases, including SARS-CoV-2, the virus which causes COVID-19.
