Palatin Announces Presentation at the 2022 Crohn's and Colitis Congress
Palatin Technologies, Inc. (NYSE American: PTN) announced a positive presentation regarding its drug PL8177 for treating ulcerative colitis at the Crohn's and Colitis Congress on January 21, 2022. The data revealed that PL8177 significantly improved colitis markers in an animal model and showed a decrease in immune response-related gene expression. Palatin plans a phase 2 clinical study for PL8177 later this year. CEO Carl Spana highlighted the importance of these findings for understanding melanocortin's role in inflammation.
- PL8177 demonstrated significant improvement in colitis markers in animal studies.
- Successful gene expression results support potential for treating inflammatory bowel disease in humans.
- Planned phase 2 clinical study for PL8177 indicates ongoing development and potential for market introduction.
- None.
CRANBURY, N.J., Jan. 21, 2022 /PRNewswire/ -- Palatin Technologies, Inc. (NYSE American: PTN), a biopharmaceutical company developing first-in-class medicines based on molecules that modulate the activity of the melanocortin peptide receptor system, announced a presentation of the positive effects of PL8177 on treating ulcerative colitis in an animal disease model, including genomic data characterizing the anti-inflammatory effects of melanocortin agonists. The poster presentation of the efficacy and cellular and molecular effects of the melanocortin 1 receptor agonist PL8177 in a rat model of ulcerative colitis will be presented at the Crohn's and Colitis Congress, being held virtually, on January 21, 2022.
The data presented showed that orally administered PL8177 improved markers of colitis compared to the vehicle group. Also, data from colon samples from the DSS rat model showed significantly lower expression of a gene involved in regulating immune response in the bowel. These results support the aim of ultimately treating inflammatory bowel disease in humans. Palatin is planning to conduct a phase 2 clinical study evaluating PL8177 administered orally as a treatment for ulcerative colitis later this year.
"The results of this ulcerative colitis study, including data from cutting edge genomic and proteomic platforms, are a demonstration of the excellent science our research team is doing, not only supporting Palatin's development programs, but also expanding knowledge about how melanocortins regulate inflammation," said Carl Spana, Ph.D., CEO and President of Palatin.

About PL8177
PL8177 is a synthetic cyclic heptapeptide with demonstrated efficacy in animal inflammatory bowel disease models. PL8177 is a potent agonist at the human melanocortin receptor-1 (MC1r), with sub-nanomolar affinity binding and EC50 functional values. Palatin data demonstrates that the oral formulation of PL8177 was protected from degradation in the stomach and small intestine and delivered to the large intestine and 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. Over 700,000 individuals in the United States are affected by ulcerative colitis, with over 350,000 diagnosed with moderate-to-severe disease. Existing treatments are not effective in a large portion of patients with moderate-to-severe ulcerative colitis, with some severe cases resulting in surgical removal of the colon.
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.
