Arketamine (R-ketamine) preliminary efficacy study

Clinical Score: 0.600 Price: $0.50 treatment-resistant depression TRD patients Status: proposed

What This Experiment Tests

Clinical experiment designed to assess clinical efficacy targeting N/A in TRD patients. Primary outcome: antidepressant efficacy with improved side effect profile

Description

Preliminary clinical investigation of arketamine (R-ketamine) as a potential improvement over racemic ketamine and esketamine for treatment-resistant depression. This early-phase study examined the R-enantiomer of ketamine, which preliminary data suggested might offer advantages including longer-lasting antidepressant effects, reduced psychomotor adverse effects, and lower potential for substance abuse. The research compared the efficacy, safety, and tolerability profile of arketamine against established ketamine formulations, with particular attention to psychotomimetic side effects and abuse liability that are concerns with current ketamine treatments.
