Could a Parkinson's drug ease radiation brain damage?
NCT ID NCT07125222
First seen Aug 03, 2026 · Last updated Aug 04, 2026 · Updated 1 time
Summary
This trial tests whether Gocovri, an extended-release form of amantadine, can reduce disability and improve cognitive function in adults who have brain damage from radiation therapy. Participants take the drug daily for about 24 weeks, with the dose increasing after the first month. The study measures changes in disability using the Disability Rating Scale and cognition using the Montreal Cognitive Assessment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Gocovri (extended-release amantadine)
- What this could lead to
- If effective, Gocovri could offer a new way to reduce disability and improve thinking in people with brain damage from radiation therapy.
- What could go wrong
- This is a small, early-phase trial, so results may not hold up in larger studies. The drug may also cause side effects, and not everyone may benefit.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Individuals ≥ 18 years of age. * Individuals with caregivers who are able to complete survey assessments for this study. * Prior brain radiation treatment. * Evidence of moderate-severe confluent white matter hyperintensity on MRI brain scan as judged by neuroradiology impression 0-5 years prior to enrollment. * DRS \> 6 * The effects of Gocovri on the developing human fetus are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (e.g. hormonal or barrier method of birth control) prior to study entry and for the duration of study participation; female subjects will be required to demonstrate a negative urine pregnancy test prior to study entry and subjects who are lactating should be excluded. Exclusion Criteria: * Pregnant or breastfeeding. * Patients with growing brain lesions or those requiring escalating doses of tumor-directed treatment.. * Patients requiring doses of Dexamethasone higher than 4 mg or escalating doses of Dexamethasone * Patients taking Amantadine or with prior usage of Amantadine. * Patients taking other dopaminergic, GABAergic, glutamatergic, or noradrenergic drugs. * Patients with a history of suicidality and depression. * Patients with end stage renal disease (creatinine clearance less than 15 mL/min/1.73 m2).
