Randomized Controlled Trial Multicenter Study
Efficacy and tolerability of the novel triple reuptake inhibitor amitifadine in the treatment of patients with major depressive disorder: a randomized, double-blind, placebo-controlled trial.
Amitifadine (EB-1010, formerly DOV 21,947) is a serotonin-preferring triple reuptake inhibitor with a relative potency to inhibit serotonin, norepinephrine, and dopamine uptake of ∼1:2:8, respectively. This 6-week, multicenter, randomized, double-blind, parallel, placebo-controlled study evaluated the efficacy and tolerability of amitifadine in 63 patients with major depressive disorder. Eligible patients (17-item Hamilton Depression Rating Scale [HAMD-17] ≥ 22 at baseline) were randomized to amitifadine 25 mg twice daily (BID) for 2 weeks, then 50 mg BID for 4 weeks or placebo. ⋯ Two patients on each treatment discontinued the study early due to adverse events; however, no serious adverse events were reported. This initial clinical trial in patients with severe major depression demonstrated significant antidepressant activity with amitifadine, including attenuating symptoms of anhedonia, and a tolerability profile that was comparable to placebo. The efficacy and tolerability of amitifadine for major depressive disorder are being investigated in additional clinical trials.
