hCG Treatment for Rehabilitation From a TBI

Официальное название

Chorionic Gonadotropin to Improve Rehabilitation After Brain Injury - The COGNI-REHAB Study

Обзор

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.

Подробное описание

This project aims to re-purpose a safe, well-tolerated, already-approved medication: human chorionic gonadotropin (hCG; choriogonadotropin alfa, Ovidrel®) for use in the post-acute rehabilitation of moderate to severe traumatic brain injury (msTBI). Ovidrel is currently FDA-approved for use in ovulation induction and Assisted Reproductive Technologies (ART). The rationale for using Ovidrel comes from a convergence of evidence indicating that hCG has neurodevelopmental and neuroregenerative properties, and from preclinical studies demonstrating that hCG reverses TBI-induced suppression of sex hormone production (i.e., reverses hypogonadism) and improves recovery of sensorimotor and spatial learning and memory in rodents following a focal injury to the medial prefrontal cortex. Recovery from a TBI is typically a very slow process because innate neuronal regeneration is a slow process; thus, Ovidrel (125 µg twice weekly) treatment will be evaluated over 24-weeks in patients that are 1-6 months post-TBI.

Вмешательства

• Препарат Ovidrel
  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),
• Другое Placebo
  Prefilled syringe of 0.250 mL normal saline.
