Protagonist Announces Two New Phase 3 ICONIC Studies in Psoriasis Evaluating JNJ-2113 in Head-to-Head Comparisons with Deucravacitinib
The ICONIC program now includes four Phase 3 studies evaluating JNJ-2113;
Co-primary endpoints for all four studies are PASI-90 and/or IGA 0 or 1
Protagonist eligible to receive $115 million milestone upon achieving the co-primary endpoints in any one of the studies
NEWARK, CA / ACCESSWIRE / November 27, 2023 / Protagonist Therapeutics, Inc. (“Protagonist” or the “Company”) today announced two additional Phase 3 studies, ICONIC-ADVANCE 1 and ICONIC-ADVANCE 2, evaluating JNJ-2113 (formerly PN-235) in head-to-head comparisons against deucravacitinib, an oral TYK2 inhibitor, in patients with moderate-to-severe psoriasis. Details regarding ADVANCE 1 are available on clinicaltrials.gov. The ICONIC program now includes four Phase 3 studies: ADVANCE 1, ADVANCE 2 and as previously announced, LEAD and TOTAL. Protagonist is eligible to receive a $115 million milestone payment upon achieving the co-primary endpoints in any one of the studies.
ICONIC-ADVANCE 1 is a Phase 3 trial evaluating the safety and efficacy of JNJ-2113 compared to both placebo and deucravacitinib. The trial’s co-primary endpoints are PASI-90 and IGA score of 0 or 1. The trial, which is expected to begin enrolling patients in the first quarter of 2024, is led by the Company’s collaboration partner, Janssen Biotech, Inc., a Johnson & Johnson company (Janssen). ICONIC-ADVANCE 2, a similarly designed study, is expected to start enrolling patients later in 2024.
“We are very pleased with the rapid progression of the ICONIC Phase 3 psoriasis program, and in particular with the design of the ICONIC-ADVANCE trials. JNJ-2113 is the only targeted oral peptide in late-stage development that is designed to selectively block the IL-23 receptor, and we believe the ICONIC studies have the potential to establish JNJ-2113 as the preferred oral treatment option for psoriasis patients,” said Dinesh V. Patel, Ph.D., President and CEO of Protagonist. “The strength of the FRONTIER 1 Phase 2b data reported in July and the robust designs for the Phase 3 program give us renewed confidence that JNJ-2113 will meet all of our objectives under the terms of our partnership with Janssen.”
Details regarding the two previously announced ICONIC Phase 3 psoriasis trials as well as the ANTHEM-UC Phase 2b study evaluating JNJ-2113 in ulcerative colitis, can be found at the following links on clinicaltrials.gov: ICONIC-LEAD, ICONIC-TOTAL and ANTHEM-UC. All of the clinical studies utilize the same once-daily, immediate-release formulation of JNJ-2113 as was used in the successful FRONTIER 1 Phase 2b study.
License and Collaboration Agreement
JNJ-2113 is a first and only targeted oral peptide that is designed to selectively block the IL-23 receptor that was jointly discovered and is being developed pursuant to the license and collaboration agreement between Protagonist and Janssen. Protagonist completed a Phase 1 study of JNJ-2113 in 2021 and Janssen retains exclusive, worldwide rights to develop in Phase 2 and beyond, and to commercialize compounds derived from the research conducted pursuant to the agreement which covers a broad range of indications.
In October 2023, Protagonist earned a $50 million milestone payment related to initiation of the ICONIC Phase 3 program. In addition, Protagonist will earn a $10 million milestone payment upon dosing of the third patient in the ANTHEM UC Phase 2b study and remains eligible for up to an additional $795 million in other development and sales milestone payments with respect to JNJ-2113. This includes a $115 million milestone to be paid upon successfully achieving the co-primary endpoints in any of the Phase 3 psoriasis clinical trials, a $50 million milestone upon NDA submission and a $35 million milestone upon NDA approval. The Company is also eligible to earn upward tiering royalties of 6%-10%, with the 10% tier applicable for net sales of greater than $4 billion.
About Protagonist
Protagonist Therapeutics is a biopharmaceutical company with peptide-based new chemical entities (NCEs) rusfertide and JNJ-2113 (formerly PN-235) in advanced stages of clinical development, both derived from the Company’s proprietary technology platform. Protagonist and Janssen scientists jointly discovered JNJ-2113 as part of Protagonist’s interleukin-23 receptor (IL-23R) collaboration with Janssen and followed it through IND-enabling pre-clinical and Phase 1 studies, with Janssen assuming responsibility for further clinical development. Rusfertide, a mimetic of the natural hormone hepcidin, is the Company’s lead drug candidate currently in a global Phase 3 development program. The randomized portion of the Phase 2 REVIVE study showed positive results and is now complete, with an open-label extension underway. The global Phase 3 VERIFY study of rusfertide in polycythemia vera is ongoing. Protagonist retains all worldwide development and commercialization rights to rusfertide.
