What PL8177 is
Palatin's oral melanocortin-1 receptor agonist peptide for ulcerative colitis, with a small Phase 2 showing 33% remission versus 0% on placebo before the study was cut short for licensing.
PL8177 is a cyclic peptide agonist of MC1R designed to act in the gut and resolve inflammation rather than suppress the immune system.

Mechanism: MC1R agonism on immune cells and gut epithelium promoting resolution of inflammation.
