Study to Investigate the Safety of the Transplantation (by Injection) of Human Glial Restricted Progenitor Cells (hGRPs; Q-Cells®) Into Subjects With Amyotrophic Lateral Sclerosis (ALS)

A Phase 1/2a Open-Label Study to Investigate the Safety of the Transplantation (by Injection) of Human Glial Restricted Progenitor Cells (hGRPs; Q-Cells®) Into Subjects With Amyotrophic Lateral Sclerosis (ALS): Assessment of Localized Therapeutic Activity by Blinded Observation and Lateral Transplantation (ALTA-BOLT)

This study is a non-randomized, open-label, partially blinded, sequential cohort, dose-escalation study designed to obtain preliminary data on the safety, tolerability, and early efficacy of Q-Cells® transplantation in subjects with ALS. Following an initial cohort receiving cell transplants unilaterally in the lumbar spinal cord, subsequent cohorts will receive escalating doses transplanted unilaterally in cervical spinal cord. Subjects and outcome measure assessors will be blinded to side of treatment. The study will be conducted at sites with extensive clinical experience with the care of patients with ALS.

Detailed Description

This study is a non-randomized, open-label, partially blinded, sequential cohort, dose-escalation study designed to obtain preliminary data on the safety, tolerability, and early efficacy of Q-Cells® transplantation in subjects with ALS. Following an initial cohort receiving cell transplants unilaterally in the lumbar spinal cord, subsequent cohorts will receive escalating doses transplanted unilaterally in cervical spinal cord. Subjects and outcome measure assessors will be blinded to side of treatment. The study will be conducted at sites with extensive clinical experience with the care of patients with ALS.

The study is planned to enroll up to 30 subjects over 24 months. Each subject will receive a single time point administration of Q-Cells®: with 5 or 10 (dependent upon dose level) transplantation foci targeted to the anterior horn in either the lumbar or cervical spinal cord.

The study consists of Screening, Pre-operative/Treatment, and Post-treatment study periods. The study data will be assessed for safety and efficacy after the last subject has completed the 9-month study visit. Following the 9-month study period, subjects who consent will continue to be followed for safety and efficacy long-term in a separate protocol.

• Study Type: Interventional
• Enrollment (Estimated): 30
• Phase: Phase 2; Phase 1

Exclusion Criteria:

1. Subject in whom causes of neuromuscular weakness other than ALS have not been practically excluded.

5. Subject with a clinically significant history of unstable cardiac, pulmonary, renal, hepatic, endocrine, hematologic, or active malignancy or infectious disease or other medically significant illness, which, in the opinion of the Investigator, would preclude study participation.
6. Subject with a history of spine surgery or anatomic variation incompatible with route of administration (as determined by neurosurgeon).
7. Subject with severe cervical or lumbar stenosis, cord compression, or cervical or lumbar myelopathy.
8. Subject with abnormal flow voids on the surface of the spinal cord suggestive of arteriovenous malformation (AVM).
9. Subject demonstrating any evidence of CNS malignancy or CNS lesions as defined by imaging studies of the CNS (MRI of brain and spinal cord).
10. Subject having uncontrolled hypertension (Systolic BP>180mmHg and/or Diastolic BP >110mmHg) or having a history of thrombotic events or poorly controlled medical conditions that, in the opinion of the Investigator and/or surgeon, increase risk of surgery.
11. Subject who cannot undergo MRI examination because of the presence of a pacemaker, an implanted defibrillator or certain other implanted electronic or metallic devices, or who have been or might have been exposed to metal fragments, or any reason the subject cannot undergo an MRI routinely for the duration of the trial.
12. Subject with clinically significant abnormal clinical laboratory values, as determined by the Investigator during the Screening Period.
13. Subject who is immune compromised or who has a condition contraindicated to treatment with immunosuppression agents (e.g., tuberculosis, latent infection).
14. Subject with an aspartate aminotransferase (AST) or alanine aminotransferase (ALT) value >3.0 times the upper limit of normal or creatinine >1.5 times the upper limit of normal and/or eGFR <50cc/min during the Screening Period.
15. Subject with a history of alcohol or drug abuse or dependence within 1 year of the first day of the Screening Period, per DSM-V criteria.
16. Subject unlikely to comply with study requirements, as determined by Investigator.
17. Subject who has been exposed to any other experimental agent (off-label use or investigational) within 30 days of the first day of the Screening Period. Biologic agents may need additional time for washout and will be evaluated by the Sponsor on a case-by-case basis.
18. Subject who has previously been administered stem cells.
19. Subject with pre-existing anti-human leukocyte antigen (HLA) class I or class II antibodies directed against the Q-Cells®, as determined by panel reactive antibody (PRA) assay during the Screening Period.

21. Subject with any medical condition or using concomitant medication that would contraindicate the use of tacrolimus, mycophenolate mofetil, or prednisone as determined by Investigator.
22. Subject with evidence of deep vein thrombosis (DVT) by venous ultrasound or any previous evidence of DVT.
23. Subject who, in the opinion of the Investigator, has taken or is taking concomitant medications, supplements, or other agents that may interfere with the safety evaluation of Q-Cells® or may affect the course of the subject's ALS progression.
