Prospective, Open Label, Cohort Study in Traumatic Brain Injury Patients. The goal of this study is to assess the safety of NTx®-265. NTx®-265 will be administered over 9 days, and patients will be followed for an additional 6 months.
Traumatic Brain Injury
Drug: NTx 265
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||A Phase IIa, Single Centre, Open Label Study to Characterize the Safety of Human Chorionic Gonadotropin (hCG) and Epoetin Alfa (EPO) in Traumatic Brain Injury: Dosing Tier 1
Primary Outcome Measures:
- Safety [ Time Frame: 6 months ]
The primary endpoint for this study is safety. The following safety endpoints will be assessed:
- Type, incidence, severity, timing, seriousness, and relatedness of adverse events.
- Lower extremity deep vein ultrasound will be performed to identify and localize deep or superficial venous thrombosis.
- Vital signs
- Laboratory assessments. Particular attention will be paid to serial hemoglobin and hematocrit measurements.
- DVT, PE, thromboembolism, MI and stroke.
Secondary Outcome Measures:
- Efficacy [ Time Frame: 6 months ]
The following secondary endpoints will also be assessed in order to measure various aspects of neurological status:
- GOSE at hospital discharge, 3, and 6 months post-TBI
- Neurobehavioral Rating Score at hospital discharge, 3, and 6 months post TBI
- Disability Rating Score at hospital discharge, 3, and 6 months post TBI
