NCT06790095

Brief Summary

The purpose of this study is to determine if experimental drug treatment improves recovery after TBI as compared to a control (placebo) group. Changes in recovery will be measured throughout the study. The study drug listed below is approved by the U.S. Food and Drug Administration (FDA) but is being used "off-label" in this study. This means that the drug is not currently approved to treat TBI.

Outcome Measures

Primary Outcomes (1)

  • Change in Disability Rating Score (DRS)

    The primary outcome measure is to determine whether the intervention safely improves functional outcome in participants with TBI as compared to placebo, as measured by the change in the Disability Rating Score (DRS) score from Baseline to Week 4 post-injury.

    Baseline to Week 4 post-injury

Secondary Outcomes (12)

  • Change in Blood-based biomarker (Neurofilament light chain)

    Baseline to Week 2 post-injury

  • Change in Blood-based biomarker (GFAP)

    Baseline to Week 2 post-injury

  • Change in Blood-based biomarker (UCH-L1)

    Baseline to Week 2 post-injury

  • Post-TBI symptom outcome (CRSR-FAST)

    Baseline to Week 4 post-injury

  • Imaging biomarkers

    Week 2 to Month 6

  • +7 more secondary outcomes

Study Arms (2)

Cyclosporine (CsA)

ACTIVE COMPARATOR

Intravenous (IV) injection, 2.5 mg/kg loading dose given over 2 hours, followed by a 3-day (72-hour) constant IV infusion of 5 mg/kg/day.

Drug: Cyclosporine (CsA)

Matching Placebo

PLACEBO COMPARATOR

Intravenous (IV) injection of 0.9% NaCl over 74 hours.

Drug: Placebo

Interventions

Intravenous (IV) injection, loading dose of 2.5 mg/kg (diluted in 0.9% NaCl to a final volume of 50 ml) given over 2 hours, immediately followed by a continuous IV infusion of of 5 mg/kg/day (diluted in 0.9% NaCl to a final volume of 250 ml) for 3 days (72-hour).

Also known as: Sandimmune®
Cyclosporine (CsA)

Intravenous (IV) injection of 0.9% NaCl with the same dosing strategy as CsA: "loading dose" given over 2 hours, immediately followed by a continuous IV infusion for 3 days (72-hour).

Matching Placebo

  • Ongoing pre-injury therapy with the Investigational Product (IP), currently receiving immunosuppressive therapy or any contraindicated medications (see CsA Drug contraindications/caution table in Manual of Procedures)
  • Current or medical history of any allergic reactions and/or anaphylactic reactions towards CsA and cremophor (also known as kolliphor®)
  • Severe polytrauma or previous conditions that would preclude conducting any study activities
  • Any spinal cord injury of grade A to D on the American Spinal Injury Association (ASIA) Impairment Scale
  • Primary diagnosis at the enrolling facility of ischemic or hemorrhagic stroke
