Palatin Presents Data at the United European Gastroenterology Week 2023 Conference On PL8177 Ulcerative Colitis Treatment
- Oral PL8177 showed significant improvements in inflamed colon health, providing potential efficacy for patients with inflammatory bowel disease.
- PL8177 treatment resolved pathological inflammation by repolarizing colon macrophages, offering a safer alternative to immunosuppressive treatments.
- None.
- Data demonstrates oral PL8177 causes diseased colons to move to a healthier state
- Provides further support for ongoing oral PL8177 Phase 2 ulcerative colitis study
"The Palatin research team continues to produce groundbreaking data demonstrating the utility and mechanism of action of melanocortin agonists in treating inflammatory diseases," said Carl Spana, Ph.D., President and CEO of Palatin. "This important mechanism of action data supports our active business development efforts for PL8177, including continued enrollment of patients in a Phase 2 ulcerative colitis study."
The poster presents data from a series of oral PL8177 dose-ranging studies in the DSS colon inflammation model and includes histological, genomic, and proteomic data. Compared to vehicle and the positive control mesalazine, PL8177 showed significant improvements in inflamed colon health, including relative increases in colon cells needed for a healthy colon. PL8177 treatment showed clear evidence of resolving pathological inflammation by repolarizing colon macrophages from a pro-inflammatory to a pro-inflammation resolving state.
Oral PL8177 caused diseased colons to move towards a healthy state and to resolve damaging inflammation. By resolving inflammation rather then blocking it, PL8177 may provide efficacy without the safety concerns of immunosuppressive treatments for patients suffering with inflammatory bowel disease.
About PL8177
PL8177 is a synthetic cyclic heptapeptide with demonstrated efficacy in multiple animal inflammatory bowel disease models. PL8177 is a potent, selective agonist at the human melanocortin-1 receptor (MC1r), with sub-nanomolar affinity binding and EC50 functional values. Palatin data demonstrates that their oral formulation of PL8177 was protected from degradation in the stomach and small intestine of humans and delivered to the colon over an extended period. In addition, orally administered PL8177 had a significant effect on resolving inflammation in a rat bowel inflammation model.
PL8177 in oral formulations has demonstrated repeated, robust efficacy in ulcerative colitis disease models. MC1r is found on epithelial cells and resident macrophages of the colon which are accessible from the lumen of the colon. Orally administered PL8177 is not systemically absorbed. PL8177 has the potential for excellent efficacy without safety concerns.
About Ulcerative Colitis
Ulcerative colitis is a chronic disease of the large intestine (colon), with inflammation and ulcerations that can cause significant abdominal pain, persistent diarrhea, loss of appetite and other symptoms. An estimated 1 million individuals in
About Melanocortin Receptor Agonists and Inflammation
The melanocortin receptor ("MCr") system has effects on inflammation, immune system responses, metabolism, food intake, and sexual function. There are five melanocortin receptors, MC1r through MC5r. Modulation of these receptors, through use of receptor-specific agonists, which activate receptor function, or receptor-specific antagonists, which block receptor function, can have medically significant pharmacological effects. Many tissues and immune cells located throughout the body, including the gut, kidney and eye, express melanocortin receptors, empowering our opportunity to directly activate natural pathways to resolve disease inflammation. Drugs based on melanocortin agonists have been approved by the FDA for treating several conditions, including female sexual dysfunction, inflammatory/autoimmune diseases, and rare forms of genetic obesity.
