About this trial
A study to assess the effect of Gocovri (extended-release amantidine) to improve disability as assessed by the disability rating scale (DRS) and cognition as assessed by the Montreal Cognitive Assessment (MoCA) test in patients with radiation encephalopathy.

Treatments tested in this trial
Gocovri (extended-release amantidine)
DrugGocovri is extended release formulation of amantidine. Starting on Day 1, patients will start Gocovri 137mg daily. If there is no dose-limited event after 28 days, the dose will be increased to 274mg daily which will become the new standard dose for the remaining 20 weeks of the patient's participation in the study.
Treatment groups
Trial outcomes
Primary outcomes
Change in the level of disability as measured by the Disability Rating Scale(DRS)
The Disability Rating Scale (DRS) is a tool used to evaluate impairment, disability and handicap caused by brain injury. Scores range from 0 (No disability) to a maximum of 29 (indicating an extreme vegetative state).
Secondary outcomes
Change in cognition based on the MoCA test.
The Montreal Cognitive Assessment (MoCA) is a brief screening tool to assess cognitive function and identify potential cognitive impairment. A score of 26-30 is considered normal, 18-25 as mild cognitive impairment, 10-17 as moderate cognitive impairment and below 10 as severe cognitive impairment.
Change in 18F-FPEB avidity on PET/CT.
