NEWARK, Calif., Jan. 7, 2020 /PRNewswire/ -- Protagonist Therapeutics, Inc. (Nasdaq: PTGX) today announced the achievement of a research milestone under its worldwide license and research collaboration agreement with Janssen Biotech, Inc. ("Janssen"), for co-development activities with affiliate Janssen Research & Development, LLC, and commercialization of oral, gut-restricted IL-23 receptor antagonist PTG-200 (JNJ-67864238) and second generation peptides for all indications including inflammatory bowel disease (IBD). The successful nomination of a second-generation development candidate triggers a $5 million milestone payment to Protagonist.

"We are highly encouraged by the progress with Janssen in the successful application of our technology platform for the discovery and development of gut-restricted IL-23 receptor antagonist peptides as oral targeted therapy for IBD," commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. "Our first product candidate PTG-200 remains on track for Phase 2 results in Crohn's disease expected in 2021. This recent milestone demonstrates both the utility of the platform and our commitment to the overall strategic objective of bringing new oral medicines to patients with IBD."

According to the terms of the agreement between Protagonist and Janssen, Protagonist is eligible to receive potential payments over the life of the collaboration. The payments are in the form of research, development, regulatory and sales milestones linked to development of PTG-200 and related compounds. Protagonist also has an option to co-detail PTG-200 and related compounds in the U.S. market.

About PTG-200 (JNJ-67864238)

PTG-200 is an oral peptide interleukin-23 receptor (IL-23R) antagonist being co-developed with Janssen for the treatment of inflammatory bowel disease and is initially in development for the treatment of patients with Crohn's disease. PTG-200 is designed to offer choices to patients in addition to injectable antibody therapeutics that target the IL-23 pathway, including the potential for improved safety and tolerability and better compliance compared to therapeutics administered by injection. Results from a Phase 1 randomized, double blind, placebo-controlled, single- and multiple-dose escalation study in healthy volunteers demonstrated that PTG-200 was well tolerated, with pharmacokinetic measures consistent with its design as a compound restricted to the gastrointestinal system. Protagonist and Janssen are jointly conducting a global, randomized, double blind, Phase 2 proof-of-concept study of PTG-200 in 90 patients with moderate to severe Crohn's disease. Additional information on the PTG-200 Crohn's disease study is available at https://clinicaltrials.gov/ct2/show/NCT04102111.
