Protagonist (PTGX) Begins Dosing in Phase I Study With PN-235


Protagonist Therapeutics, Inc.


PTGX

announced that it has dosed the first patient in a phase I study, evaluating its oral interleukin-23 receptor (IL-23R) antagonist peptide – PN-235 (also known as JNJ-77242113).

The early-stage study is being conducted as a part of Protagonist Therapeutics’ ongoing collaboration with Janssen Biotech, Inc., a wholly owned subsidiary of

Johnson & Johnson


JNJ

.

Per the company, PN-235 was discovered through Protagonist Therapeutics’ peptide technology platform and is the first second-generation oral IL-23 receptor antagonist to enter clinical development. The phase I study will evaluate the safety, tolerability and pharmacokinetics of oral PN-235 in around 100 healthy volunteers. The company remains focused to see its potential for multiple indications targeting the well-validated IL-23 pathway. Results from the phase I study are expected in 2021.

Shares of Protagonist Therapeutics were up 9.9%, following the announcement of the news on Wednesday. In fact, the stock has skyrocketed 207.9% so far this year compared with the

The phase I study on PN-235 will be categorized in three parts, namely – a single ascending dose, a multiple ascending dose and a randomized, crossover solid dose comparison part. The primary endpoint of the study will check the safety as measured by the number and severity of adverse events.

Notably, Protagonist Therapeutics has a co-development and commercialization agreement with Janssen for IL-23 receptor-targeted therapies targeting various indications. Per the agreement, Protagonist Therapeutics will be eligible to receive development and sales-based milestone payments if a product is commercialized from the collaboration. Janssen, on the other hand, will lead further development/commercialization activities of candidates beyond the phase II study.

We remind investors that Protagonist Therapeutics and Janssen Biotech are currently evaluating PTG-200, an oral IL-23 receptor antagonist, in a phase II study for the treatment of Crohn’s disease.

Protagonist Therapeutics is also evaluating the safety, tolerability and efficacy of PN-943, an oral alpha-4-beta-7 integrin antagonist, in a phase II study for treating moderate-to-severe ulcerative colitis.
