Brief Summary
The COGNI-REHAB Trial is a single-site, phase O/I, randomized, double-blind, placebo-controlled study of human chorionic gonadotropin (hCG; choriogonadotropin alfa, Ovidrel®) in men with post-acute, moderate to severe traumatic brain injury (msTBI). Its objective is to assess the safety and efficacy of a 24-week regimen of Ovidrel (125 micrograms twice weekly) compared to placebo on treatment-emergent adverse events (TEAEs), cognitive and functional recovery, and circulating sex hormones.

Study Arms (2)
Treatment Arm
EXPERIMENTALOvidrel: 125 micrograms in 0.25 mL administered subcutaneously twice weekly for 24 weeks
Placebo Arm
PLACEBO COMPARATORPlacebo: 0.25 mL of sterile normal saline administered subcutaneously twice weekly for 24 weeks
Interventions
Ovidrel, recombinant human chorionic gonadotropin, comes in a prefilled syringe for subcutaneous injection, is the investigational agent that will be used in this trial. Ovidrel® PreFilled Syringe is a sterile, liquid intended for subcutaneous (s.c.) injection. Each Ovidrel® PreFilled Syringe is filled with 0.515 mL containing 257.5 micrograms of choriogonadotropin alfa, 28.1 mg mannitol, 505 g 85% O-phosphoric acid, 103 g L-methionine, 51.5 g Poloxamer 188, Sodium Hydroxide (for pH adjustment), and Water for Injection to deliver 125 micrograms of choriogonadotropin alfa in 0.25 mL twice weekly. The pH of the solution is 6.5 to 7.5.

- Presence of significant systemic illness likely to interfere with participation in or completion of the study or to affect study results
- Receiving other investigational drugs within 30 d or 5 half-lives prior to randomization, whichever longer
- Male patients with known/documented elevated PSA levels, or a PSA level of 4ng/mL at screening
- History of deep venous thrombosis (DVT) or venous thromboembolism (VTE)
- Clinically significant peripheral edema

- Patients with known hypercoagulability, including cardiolipin/antiphospholipid antibody syndrome
- Allergy or other contraindication to hCG
- Uncontrolled hypertension, defined as blood pressure persistently above 140 mm Hg systolic or 95 mm Hg diastolic despite antihypertensive therapy
- +6 more criteria
