NCT07557615

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

EXPERIMENTAL

Ovidrel: 125 micrograms in 0.25 mL administered subcutaneously twice weekly for 24 weeks

Drug: Ovidrel

Placebo Arm

PLACEBO COMPARATOR

Placebo: 0.25 mL of sterile normal saline administered subcutaneously twice weekly for 24 weeks

Other: Placebo

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.
