Trelanserin (INNTooltip International Nonproprietary Name; developmental code name SL 65.0472) is a dual serotonin 5-HT1B receptor antagonist and serotonin 5-HT2A receptor antagonist which was under development for the treatment of peripheral arterial occlusive disorders and thrombosis but was never marketed.[1][2][3][4] It is taken orally.[1] The drug was under development by Sanofi-Aventis.[1][2] It reached phase 2 clinical trials prior to the discontinuation of its development in 2009.[1][2][3] Trelanserin was first described in the scientific literature by 2000.[5]

PMID 19548849. 2.3.10 SL-65.0472 (SL-650472, SL650472) SL-65.0472 (SL-650472, SL650472; Sanofi-Aventis) is a 5HT1B/2A antagonist for the treatment of PAO. The molecule prevents local vasoconstriction and platelet aggregation and has antiproliferative activity at sites where atherosclerotic endothelium is present. The compound was in Phase IIb trial (MASCOT) in intermittent claudication Fontaine Stage II patients. However, it has been discontinued due to an inadequate risk–reward profile.
