Lineage Announces FDA Clearance of IND Amendment for OPC1 Cell Transplant for the Treatment of Spinal Cord Injury - Seite 2

OPC1 has been tested in two clinical trials to date: a five patient Phase 1 clinical safety trial in acute thoracic SCI, where all subjects have been followed for at least 10 years; as well as a 25 patient Phase 1/2a multicenter dose-escalation clinical trial in subacute cervical SCI, where all subjects were evaluated for at least two years, one of the first cell therapy clinical trials supported by the California Institute for Regenerative Medicine under Proposition 71. Results from both studies have been published in the Journal of Neurosurgery: Spine. The data from the Phase 1/2a clinical study of OPC1 in subacute cervical SCI is available here and the data from the Phase 1 clinical study of OPC1 in acute thoracic SCI is available here.

About the DOSED Clinical Study

The Delivery of Oligodendrocyte Progenitor Cells for Spinal Cord Injury: Evaluation of a Novel Device (DOSED) clinical study is an open label, multi-center, device safety study, in approximately 3-5 subacute and 3-5 stable chronic subjects with complete (ASIA Impairment Scale A) or incomplete (ASIA Impairment Scale B), traumatic, focal SCI affecting either cervical (C4-C7) or thoracic (T1-T10) vertebrae. The primary objective of this study is to evaluate the safety of a novel spinal cord delivery device to administer OPC1 to the spinal parenchyma. The primary endpoint is safety, as measured by the frequency and severity of adverse events (AEs) through 30 days following OPC1 injection that are related to the injection procedure. Secondary endpoints are safety and tolerability, as measured by the frequency and severity of AEs, including AEs of special interest, through 90 days following OPC1 injection, that are related to OPC1 and/or the concomitant short-term immunosuppression. Safety parameters will be evaluated by magnetic resonance imaging (MRI) data evaluating evidence of deterioration or changes in the following: intramedullary hemorrhage, cerebral spinal fluid (CSF) leak, epidural abscess, infection; evidence of an expanding cyst or mass at the injection site or elsewhere in the central nervous system (CNS); evidence of inflammatory lesion(s) at injection site or elsewhere in CNS and evidence of CSF flow obstruction. Exploratory endpoints include: (1) potential improvements in neurological impairment, function, and pain, evaluated by changes from baseline on the following endpoints: changes in neurological function as measured by sensory and motor scores and motor level on International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) examinations; changes in post-injection pain, defined as a worsening of pain or neuropathic pain of greater than 7 days duration from baseline levels, as assessed by the International Spinal Cord Injury Pain Basic Data Set or occurrence of allodynia; (2) changes from baseline at 30, 90 and 365 days post-OPC1 injection in: ISNCSCI, SCIM, International Spinal Cord Injury Pain Questionnaire; and (3) patient and clinician impressions of changes in quality of life as reported by changes from baseline at 30, 90, and 365 days post-OPC1 injection.
