Clinical Study of an Autologous Stem Cell Product in Patients With a (Sub)Acute Spinal Cord Injury

Clinicaltrials.gov identifier NCT03935724

Recruitment Status Not yet recruiting

Study Description

Brief summary:

This is a multicenter, randomized, double-blind, placebo-controlled and delayed-start phase II/III clinical study.

  • Condition or Disease:Spinal Cord Injuries
    Acute Spinal Cord Injury
    Paraplegia, Spinal
    Paraplegia; Traumatic
  • Intervention/Treatment: Biological: Neuro-Cells
  • Phase: Phase 2/Phase 3
Detailed Description

Phase II of the study focuses on establishing the safety and efficacy of the fist-in-human administration of Neuro-Cells. In phase III efficacy and safety will be further investigated. Enrollment in phase III of the study will automatically start once all patients have been enrolled and treated in phase II. The recruitment period is estimated at respectively 6 months for both the Phase II and Phase III. Phase II starts with the enrollment of 16 evaluable patients, randomly divided in two groups of 8 evaluable patients each. After an interim intervention analysis, the phase II study expands into a phase III study, requiring the recruitment of 54 additional evaluable patients. Patients recruited for the phase III part will be randomly divided in two groups of 27 evaluable patients each. Details on the planned analyses can be found in section 8 'Statistical Analysis'. Both the phase II and phase III part of the trial have a similar setup which includes a screening period (1 - 2 days), a randomization, a treatment period of 1 or 2 days and a total follow-up period of 1 year. All patients undergo a BM harvesting at the start of their participation in the study and will undergo three LPs, performed to administer Neuro-Cells or placebo and/or to collect CSF for research purposes. Neuro-Cells and placebo are both administered as a single dose by an 'unblinded physician'. This physician is different from the 'blinded Investigators and study nurses' responsible for patient selection and follow-up. This study set-up allows to maintain a double-blind status of the patients and the Investigators responsible for the patients' evaluation throughout the first six months of both studies. This is because, approximately six months after the time of inclusion, the patients assigned to the placebo group will undergo a second BM harvesting and will also receive Neuro-Cells. All patients are followed up until approximately one year after the time of inclusion. All patients will have been treated with Neuro-Cells and will have completed follow-up for at least 6 months post-treatment. Patient recruitment, randomization and blinding, and the primary and secondary objectives are identical in the phase II and the phase III part of the study. The study is completed when the last patient finishes his/her last visit, approximately one year after the time of inclusion.

Study Design
  • Study Type: Interventional
  • Estimated Enrollment: 70 participants
  • Allocation: Randomized
  • Intervention Model: Parallel Assignment
  • Intervention Model Description: Patients are randomized into two groups. First groups receives Neuro-cells, second group receives placebo. After six months second group also receives Neuro-cells. This happens in phase 2 and is repeated in phase 3. Therefore there are 4 groups.
  • Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
  • Primary Purpose: Treatment
  • Official Title: A Multi-center, Double-blind, Randomized, Placebo-controlled, Delayedstart Phase II/III Study to Assess the Efficacy and Safety of Neuro-Cells in (Sub)Acute Spinal Cord Injury Patients
  • Estimated Study Start Date: October 2020
  • Estimated Primary Completion Date: October 2021
  • Estimated Study Completion Date: October 2022
Arms and interventions
Arm Intervention/treatment
Experimental: 1A Intervention group 8 patients
Neuro-Cells treatment at day 1-2 (= 6-8 weeks after TSCI incident). N=8
Biological: Neuro-Cells
Neuro-Cells is an autologous fresh stem cells containing product which modulates the secondary inflammation following a TSCI, reduces apoptosis (cell death) in the injured spinal cord, reduces scar tissue formation in the damaged spinal cord and creates a cell regenerative environment in the injured spinal cord.
Placebo Comparator: 1B Placebo group 8 patients
Placebo treatment at day 1-2 (= 6-8 weeks after TSCI incident) Neuro-Cells treatment at day 181-182 (= 32-34 weeks after TSCI incident) N=8
Biological: Neuro-Cells
Neuro-Cells is an autologous fresh stem cells containing product which modulates the secondary inflammation following a TSCI, reduces apoptosis (cell death) in the injured spinal cord, reduces scar tissue formation in the damaged spinal cord and creates a cell regenerative environment in the injured spinal cord.
Experimental: 2A Intervention group 27 patients
Neuro-Cells treatment at day 1-2 (= 6-8 weeks after TSCI incident) N=27
Biological: Neuro-Cells
Neuro-Cells is an autologous fresh stem cells containing product which modulates the secondary inflammation following a TSCI, reduces apoptosis (cell death) in the injured spinal cord, reduces scar tissue formation in the damaged spinal cord and creates a cell regenerative environment in the injured spinal cord.
Placebo Comparator: 2B Placebo group 27 patients
Placebo treatment at day 1-2 (= 6-8 weeks after TSCI incident) Neuro-Cells treatment at day 181-182 (= 32-34 weeks after TSCI incident) N=27
Biological: Neuro-Cells

Outcome Measures
  • Primary Outcome Measures: 1. Physical changes after intrathecal intervention with Neuro-Cells [ Time Frame: 9 months ]
    At approx. 3 months after intrathecal intervention with Neuro-Cells (day 90 for the patients treated 6-8 weeks after the TSCI incident and day 270 for the patients treated at 32-34 weeks after the TSCI incident) a physical examination (checklist) will be done
  • 2. Increase of motor scores after intrathecal invervention with Neuro-Cells [ Time Frame: 6 months ]
    Increase in the ISNCSCI motor scores with additional 5 points from baseline (visit 2) at 6 months after the intrathecal intervention (day 180) in patients treated with Neuro-Cells
  • Secondary Outcome Measures: 1. Increase of motor scores after late administration of Neuro-Cells [ Time Frame: 12 months ]
    Increase in the ISNCSCI motor scores with additional 5 points from baseline (visit 5) at 6 months after the intrathecal intervention (day 360) in patients treated with Neuro-Cells 32 to 34 weeks after the TSCI incident as compared to placebo treated patients
  • 2. Change in autonomic and sensoric neurological dysfunctionafter intrathecal invervention with Neuro-Cells [ Time Frame: 12 months ]
    The American Spinal Injury Association (ASIA) Impairment Scale involves both a Motor and Sensory examination for each side of the body (left/right). The Sensory examination involves 'light touch' and 'pinprick' for each dermatome (28) on both sides of the body (total 56). A score of 0, 1 or 2 can be given to each dermatome resulting in a total max. of 112 points. The Motor level is determined by examining the muscle function within each of the 10 myotomes on each side of the body (20 myotomes in total). A score ranging from 1 to 5 can be given resulting in a maximum score of 100. The higher the value, the better the outcome.
