— PN-10943 begins clinical development as a potential novel oral therapy for patients with inflammatory bowel disease —
NEWARK, CA, USA I December 13, 2018 I Protagonist Therapeutics, Inc. (Nasdaq: PTGX) today announced the initiation of dosing in the Phase 1 study of PN-10943, an oral, gut-restricted alpha-4-beta-7 integrin antagonist peptide in development for the potential treatment of inflammatory bowel disease. The study is designed to evaluate safety, tolerability, pharmacokinetics and pharmacodynamic parameters of PN-10943.
“This study builds on our previous clinical studies that investigated an oral, gut-restricted approach for the treatment of inflammatory bowel disease,” commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. “PN-10943 has been designed with superior potency and preclinical properties and applies the same oral, gut-restricted approach to treatment that has been validated previously by Protagonist in clinical studies in ulcerative colitis patients. We expect to report top-line results from this Phase 1 study in the first half of 2019 which will include safety, pharmacokinetic and pharmacodynamic readouts of target engagement as measured by blood receptor occupancy. The Phase 1 data will be used to design a Phase 2a study in ulcerative colitis patients expected to begin in the second half of 2019.”
The Phase 1 study is a randomized, double-blind, placebo-controlled, dose escalation (100, 300, 1000 and 1400 mg) trial in up to 80 normal healthy volunteers. The first part of the study consists of single ascending doses of PN-10943. The second part of the study will involve once daily administration of PN-10943 over 14 consecutive days in escalating dose cohorts. Primary endpoints for the study are safety and tolerability. Secondary endpoints include evaluation of pharmacokinetic properties and pharmacodynamic parameters of blood receptor occupancy.
