NCT05826912

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 drugs listed below are approved by the U.S. Food and Drug Administration (FDA) but are being used "off-label" in this study. This means that the drugs are not currently approved to treat TBI.

Outcome Measures

Primary Outcomes (1)

  • Change in Glasgow Outcome Scale-Extended (GOSE 2-Way)

    Functional impairment due only to the TBI will be measured using the GOSE Scale-Extended (GOSE 2-Ways). The score ranges from 1-8, with higher scores indicating better recovery. Change will be measured from Week 2 to Month 3 postinjury and compared to placebo.

    2 weeks to 3 months postinjury

Secondary Outcomes (5)

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

    Week 2

  • Blood-based biomarker (GFAP)

    Week 2

  • Imaging biomarkers

    2 weeks to 3 months postinjury

  • Post-TBI cognitive outcome (BTACT)

    Day 3 to Week 4 postinjury

  • Post-TBI symptom outcome (Rivermead)

    Day 3 to Week 4

Study Arms (4)

Intervention 1: Atorvastatin calcium (ATOR)

ACTIVE COMPARATOR

By Mouth (PO) Twice a day (BID) 80 mg/day, with no loading dose, for 28 days

Drug: Atorvastatin Calcium

Intervention 2: Minocycline hydrochloride (MINO)

ACTIVE COMPARATOR

By Mouth (PO) Twice a day (BID) 200 mg loading dose on Day 1, then 100 mg twice daily for 6 days, then placebo twice daily for 21 days

Drug: Minocycline Hydrochloride

Intervention 3: Candesartan cilexetil (CAND)

ACTIVE COMPARATOR

By Mouth (PO) Twice a day (BID) 8 mg once on Day 1, then 16 mg daily for 27 days

Drug: Candesartan Cilexetil

Matching Placebo

PLACEBO COMPARATOR

By Mouth (PO) Twice a day (BID) 2 capsules 2x/day

Drug: Placebo

You may qualify if:

  • Closest, prior to Randomization Glasgow Coma Scale (GCS) score of 9 to 15
  • Acute trauma-related neuroimaging abnormality (subarachnoid hemorrhage, contusion, subdural hematoma, petechial hemorrhage, intraventricular hemorrhage) on cranial CT (CT+)
  • Initial Glial Fibrillary Acidic Protein (GFAP) blood level \>100 pg/ml ≤ 15,000 pg/ml determined using a for Research Use Only (RUO) assay(s) or an Investigation Use Only (IUO) assay(s)
  • Persons of childbearing potential (i.e., those not postmenopausal or surgically sterile) may participate provided that they are using adequate birth control methods for the duration of investigational product administration (see manual of procedures for adequate birth control methods)
  • Participants able to undergo Magnetic Resonance Imaging (MRI) scans, no contraindications
  • Participants or legally authorized representative (LAR) willing and able to provide informed consent
  • Participants or LAR able to read, speak, and understand English or Spanish (participating site dependent, where available), including the informed consent form (ICF)
  • Willingness and ability to comply with all study procedures, treatment, and follow-up

You may not qualify if:

  • Isolated epidural hematoma
  • Pre-existing conditions including disabling developmental, neurologic, psychiatric, medical disorder that continues to produce functional disability up to the time of injury; or imminent death based on clinical judgement
  • Current enrollment in another interventional study
  • Currently pregnant or currently breastfeeding or planning on becoming pregnant in the next 6 months
  • Current incarceration or in custody
  • Currently prescribed one of the investigational products (or other drugs in the same class) prior to injury; or contra-indicated or as listed in the appendices
  • Hypersensitivity or intolerance to investigational products or the investigational products' respective classes
  • Renal dysfunction (Creatinine Clearance (CrCl) or estimated Glomerular Filtration Rate (eGFR) (\<60 mL/minute/1.73 m2)

  • Inability to swallow investigational product capsule
  • Unable or unwilling to consume animal byproducts, has a gelatin allergy, and/or religious beliefs that do not permit consuming gelatin
  • Intolerance to small amounts of lactose (less than ½ teaspoonful) daily
  • Low likelihood of follow up or study compliance, or any other reason, in the opinion of the participating site investigator, the participants should not participate in the study
