for Spinal Cord Injury
OPC1 is an oligodendrocyte progenitor cell therapy that is currently in a Phase 1/2a multicenter clinical trial for acute spinal cord injuries (SCI).
Oligodendrocyte progenitor cells (OPCs) are naturally-occurring precursors to the cells which provide electrical insulation for nerve axons in the form of a myelin sheath. SCI occurs when the spinal cord is subjected to a severe crush or contusion injury and typically results in severe functional impairment, including limb paralysis, aberrant pain signaling, and loss of bladder and sexual function. Based on the multiple reparative properties associated with OPC1, we believe this candidate cell therapy product is ideally suited to treat neurological conditions such as SCI and other demyelination and demyelination disorders of the central nervous system.
OPC1 has received a regenerative medicine advanced therapy (RMAT) and Orphan Drug designations from the FDA, which include accelerated programs intended to facilitate the development and review process, including early interactions with FDA during clinical development and enhanced favorability for marketing approval.

There are approximately 18,000 new spinal cord injuries annually in the U.S. (NSCIC SCI Facts and Figures at a Glance (2019), and there are currently no drugs approved by the FDA specifically for the treatment of SCI.
OPC1 has been tested in two clinical trials to date; a five patient Phase 1 safety trial and a 25 patient Phase 1/2a dose escalation trial (the “SCiStar trial”). The clinical development of OPC1 has been partially funded by a $14.3 million grant from the California Institute for Regenerative Medicine.
In January 2019, top line data was announced from the SciStar trial:
For a more details about the Phase 1/2a study, please see the press release here (originally issued by Asterias).
In November 2019, we reported positive results from the ongoing SciStar study of OPC1, where the overall safety profile of OPC1 has remained excellent with robust motor recovery in upper extremities maintained through Year 2 patient follow-ups available to date. In July 2020, we reported that following the transfer of OPC1 manufacturing to our cGMP manufacturing facility in Israel, key process improvements have been developed and implemented. Lineage also strengthened its patent position in order to protect the OPC1 processes, product and composition, and methods of use. In December 2020, Lineage reported it has developed an enhanced differentiation process, leading to major improvements in production and quality of its OPC1 cell therapy drug product.
In February 2021, we announced that we had entered into an exclusive option and license agreement with Neurgain Technologies, Inc., a medical device company that is commercializing technology developed by neurosurgeons at the University of California San Diego. Under the terms of the agreement, the Company and Neurgain will collaborate on the clinical testing of Neurgain’s novel Parenchymal Delivery Injection (“PDI”) system, which is designed to allow for the administration of cells to the spinal cord without stopping the patient’s respiration. Elimination of the need to stop respiration during surgery is expected to reduce the complexity, risk, and variability of administering cells to the area of injury. Lineage plans to evaluate the Neurgain PDI system’s ability to safely and effectively deliver OPC1, Lineage’s allogeneic oligodendrocyte progenitor cell (OPC) transplant, to the spinal cord in both preclinical and clinical studies.
