NEWARK, CA / ACCESSWIRE / November 7, 2024 / Protagonist Therapeutics (Nasdaq:PTGX) ("Protagonist" or "the Company") today reported financial results for the third quarter ended September 30, 2024, and provided a corporate update.

"Protagonist is approaching multiple transformational events with the pending readouts of JNJ-2113 in Phase 3 psoriasis studies this year, Phase 2b ulcerative colitis study in Q1 2025, and rusfertide Phase 3 study in polycythemia vera in Q1 2025," said Dinesh V. Patel, Ph.D., the Company's President and CEO. "In addition, we look forward to unveiling more details on an IL-17 oral peptide antagonist development candidate later this year, as well as other development candidates from our hematology and obesity programs in 2025. Our strong cash position affords us the flexibility to progress them independently into pre-clinical and clinical development over the coming years."

Upcoming Milestones

Rusfertide: Subcutaneous Injectable Hepcidin Mimetic for Polycythemia Vera (PV)

Third Quarter 2024 Financial Results

• Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities as of September 30, 2024, were $583.3 million as compared to $341.6 million as of December 31, 2023.

• License and Collaboration Revenue: The Takeda Collaboration Agreement included a one-time nonrefundable upfront payment of $300.0 million, of which we recognized $255.0 million during the first quarter of 2024. The remaining $45.0 million was recorded as deferred revenue to be recognized over time as the Company satisfies its performance obligation to complete the ongoing Phase 3 VERIFY trial for rusfertide.

  During the third quarter of 2024, we recognized $4.7 million of this deferred revenue balance as revenue based on costs incurred in the quarter compared to the total budget for this performance obligation. License and collaboration revenue of $263.8 million for the nine months ended September 30, 2024, was comprised of: (i) $255.0 million of the $300.0 million upfront cash payment for the Takeda Collaboration Agreement recorded in the first quarter of 2024, and (ii) a total of $8.8 million recorded as revenue during the second and third quarters of 2024.

• Research and Development ("R&D") Expenses: Increased by $5.3 million and $12.0 million for the three and nine months ended September 30, 2024, respectively, from the prior year periods. The increases were primarily due to increases in drug discovery and pre-clinical research expenses.

• General and Administrative ("G&A") Expenses: Increased by $2.5 million for the three months ended September 30, 2024, from the prior year period primarily due to increases in stock-based compensation and other personnel-related expenses. The increase of $9.1 million in G&A expenses for the nine months ended September 30, 2024, from the prior year period was primarily due to $4.6 million in one-time advisory and legal fees related to the Takeda collaboration and increases in stock-based compensation and other personnel-related expenses.

• Net Income (Loss): Net loss was ($33.2) million, or ($0.54) per basic and diluted share, for the three months ended September 30, 2024, as compared to a net loss of ($34.1) million, or ($0.58) per basic and diluted share, for the three months ended September 30, 2023. Net income was $143.5 million, or $2.34 per basic share and $2.22 per diluted share, for the nine months ended September 30, 2024, as compared to a net loss of ($106.3) million, or ($1.91) per basic and diluted share, for the nine months ended September 30, 2023.

About Protagonist

Protagonist Therapeutics is a late-stage development biopharmaceutical company. Two novel peptides derived from Protagonist's proprietary discovery platform are currently in advanced Phase 3 clinical development, with New Drug Application submissions to the FDA potentially in 2025. JNJ-2113 is an oral Interleukin-23 receptor (IL-23R) antagonist licensed to Johnson & Johnson (JNJ) that is currently in Phase 3 development for psoriasis and is nearing completion of Phase 2b development for ulcerative colitis. Following JNJ-2113's joint discovery by Protagonist and JNJ scientists pursuant to the companies' IL-23R collaboration, Protagonist was primarily responsible for development of JNJ-2113 through Phase 1, with JNJ assuming responsibility for development in Phase 2 and beyond. Rusfertide, a mimetic of the natural hormone hepcidin, is currently in Phase 3 development for the rare blood disorder polycythemia vera (PV). Rusfertide is being co-developed and will be co-commercialized with Takeda Pharmaceuticals pursuant to a worldwide collaboration and license agreement entered into in 2024 under which the Company remains primarily responsible for development through NDA filing. The Company also has a number of pre-clinical stage oral drug discovery programs addressing clinically and commercially validated targets, including IL-17, hepcidin mimetic, and anti-obesity programs.
