Nelotanserin (former developmental code name APD-125) is a drug developed by Arena Pharmaceuticals which acts as an inverse agonist on the serotonin receptor subtype 5-HT2A and was under development for the treatment of insomnia.[1] It was shown to be effective and well tolerated in clinical trials,[2][3] but development was halted in December 2008 because the substance did not meet the trial's effectiveness endpoints.[4] Research continues on newer analogues which may potentially be more successful.[5] More recently, nelotanserin has been repurposed for the treatment of Lewy body disease.[6] As of 2017, it is in phase II clinical trials for this indication.[6]
