Oral PL-8177 Reduces Gut Inflammation in Rat Model of IBD, New Results Show
Palatin Technologies', investigational PL-8177, taken orally, reached the large intestine and colon, resulting in significantly reduced inflammation and damage in a bowel inflammation rat model. The poster on the study, titled “Probing the Role of the MC1 Receptor in Resolution With a Selective MC1 Receptor Agonist—PL-8177” was presented at the "The Resolution of Inflammation in Health and Disease" Keystone Symposia held March 24-28 at the Royal Dublin Society, Dublin, Ireland. PL-8177 is a highly selective melanocortin 1 (MC1) receptor agonist, previously shown to prevent and reverse intestinal inflammation, similarly to the MC1 receptor natural agonist, the alpha-melanocortin stimulating hormone (alpha-MSH). Activating MC1 receptor is a natural mechanism shown to reduce inflammation and immune responses in the intestine. In IBD, the levels of MC1 receptors are increased and detected on the cell surface of intestinal cells. Researchers tested three different doses of oral PL-8177 administered twice daily in a rat model of colitis. The results showed that oral PL-8177 was released in the colon and progressed through the rat intestinal tract in nine hours. Compared to untreated rats used as controls, treatment with PL-8177 significantly improved inflammation and reduced damage to the intestine to a similar degree as in rats treated with sulfasalazine (sold unde
