Dopaminergic Therapy for Anhedonia - 2
NCT06075771 · Status: RECRUITING · Phase: PHASE4 · Type: INTERVENTIONAL · Enrollment: 70
Last updated 2026-01-28
Summary
The purpose of this 8-week, double-blind, placebo-controlled, study is to explore new treatment options for people with depression who have high inflammation and anhedonia. Seventy male and female participants with depression, between 25-55 years of age, with higher levels of inflammation and anhedonia will be randomized to receive L-DOPA or matched placebo over 8 weeks. Participants will complete lab tests, medical and psychiatric assessments, motivation and motor tasks, and MRI scans as part of the study. The total length of participation is approximately 10 to 12 weeks.
Conditions
- Anhedonia
- Depression
Interventions
- DRUG
-
Carbidopa Levodopa
Patients will receive between one and three tablets per day of 150 mg L-DOPA (administered with 37.5 mg carbidopa) to achieve doses ranging from 150 to 450 mg/day.
- DRUG
-
A placebo is a sugar pill that has no therapeutic effect and will be administered orally. Participants will receive between one and three placebo tablets per day matching the Carbidopa Levodopa tablet.
