safety of maraviroc for post-stroke depression

Conditions: Post-stroke Depression

Summary: post-stroke depression (psd) is a barrier to effective rehabilitation and recovery after stroke. current treatment options are limited and there is an unmet need for specific and effective therapeutic options. objective: to examine the safety and efficacy of maraviroc, a ccr5 antagonist, as a possible add-on treatment option for psd, in an open-labeled proof-of-concept clinical trial. design, setting, and participants: a 10-week trial of daily oral 300 mg maraviroc in ten patients with subcortical stroke suffering from psd. follow-up: eight weeks after completing treatment. main outcome measure: a change in the montgomery-asberg depression rating scale (madrs).
