Key Patent is Issued Covering Protagonist Therapeutics' Alpha4Beta7 Integrin Peptide Inhibitors including Oral Drug Candidate PTG-100
"This new patent provides intellectual property coverage until 2035 for our orally stable alpha4beta7 integrin peptide inhibitors," said
PTG-100 is a potential first-in-class oral, alpha4beta7 integrin-specific antagonist peptide product candidate which has now completed a Phase 1 clinical trial in normal healthy volunteers (NHVs), and is being developed initially for potential treatment of moderate-to-severe ulcerative colitis (UC). Alpha4beta7 integrin is considered to be one of the most gastrointestinal-specific biological targets for inflammatory bowel disease due to its binding to MAdCAM-1, an extracellular protein that resides mostly in the gastrointestinal (GI) vasculature.
PTG-100, a potential first-in-class oral alpha4beta7 integrin antagonist that is being developed initially for moderate-to-severe ulcerative colitis, has now completed a phase 1 clinical trial in normal healthy volunteers. PTG-200, a potential first-in-class oral Interleukin-23 receptor antagonist is being developed initially for moderate-to-severe Crohn's disease and is currently in IND-enabling studies.
The company has a peptide technology platform that enables the discovery of oral and injectable peptides that can be utilized against a diverse set of targets and diseases including, but not confined to the GI. In addition to PTG-100 and PTG-200, the company is engaged in the discovery and development of injectable hepcidin mimetics, including one lead compound from this program, PTG-300, which is currently in pre-clinical development. These mimetics have potential utility for the treatment of iron overload disorders, such as beta-thalassemia and hereditary hemochromatosis (HH), each of which may qualify PTG-300 for orphan drug designation.
