Liafensine (BMS-820836) is a serotonin-norepinephrine-dopamine reuptake inhibitor (SNDRI) which was under development by Bristol-Myers Squibb for the treatment of major depressive disorder.^[1]^[2] Though it demonstrated comparable effectiveness to escitalopram and duloxetine in phase II clinical trials, development was paused in 2013 because liafensine failed to show superior effectiveness relative to these drugs, a decision that was made likely based on its increased capacity for side effects as well as potential for abuse.^[1] Another clinical trial of liafensine began in 2022.^[3]
