Protagonist Receives $34 Million from Warrant Exercises

Estimated cash runway now extended through Q1 2026

NEWARK, CA / ACCESSWIRE / August 9, 2023 / Protagonist Therapeutics (NASDAQ:PTGX) (“Protagonist” or “the Company”) today announced it has received approximately $34.4 million in proceeds from the exercise of warrants to purchase 2.75 million shares of the Company’s Common Stock. The warrants were issued in connection with an August 2018 equity financing and expired on August 8, 2023.

“These proceeds make Protagonist’s cash position even stronger, with an estimated cash runway through the first quarter of 2026,” said Dinesh V. Patel, Ph.D., President and CEO of Protagonist. “Importantly, that estimate does not include $200 million in potential milestones associated with a successful Phase 3 study, NDA filing, and approval of JNJ-2113 in psoriasis,” Dr. Patel continued.

The warrants were exercised for 44,748 shares of Common Stock and pre-funded warrants to purchase 2,705,252 shares of Common Stock.

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 scientists jointly discovered PN-235 (now known as 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 Phase 2 REVIVE study 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.
