Velusetrag (INN,[1] USAN; previously known as TD-5108) is an experimental drug candidate for the treatment of gastroparesis, chronic constipation and irritable bowel syndrome.[2] It is a potent, selective, high efficacy 5-HT4 receptor agonist.[3] In clinical trials, velusetrag was efficacious and well tolerated in patients with chronic constipation,[4] and showed accelerated intestinal and colonic transit after single dosing and accelerated gastric emptying after multiple dosing.[5]

As of August 31, 2015, clinical trials for chronic constipation and Alzheimer's disease seem to be terminated.[6] One study exploring the efficacy and safety of velusetrag in idiopathic or diabetic gastroparesis is recruiting participants.[7]
