Protagonist Therapeutics Reports Fourth Quarter and Full Year 2019 Financial Results

NEWARK, Calif., March 10, 2020 /PRNewswire/ -- Protagonist Therapeutics, Inc. (Nasdaq:PTGX) today reported its financial results for the fourth quarter and full year ended December 31, 2019, and provided an update on its clinical development programs.

"We are pleased to have made great progress in 2019, creating multiple opportunities to execute on our clinical development plans with three platform-generated therapeutic candidates," commented Dinesh V. Patel, Ph.D., Protagonist President and Chief Executive Officer. "Our priorities for 2020 include evaluating PTG-300 in multiple blood disorders with the intent of selecting the first clinical indication for a pivotal study, continuing Phase 2 development of PTG-200 with our partner Janssen Biotech, and advancing PN-943 into Phase 2 development in ulcerative colitis. Our financial position provides us with sufficient resources through the end of 2021 which should enable us to reach definitive conclusions for all of the ongoing clinical proof of concept studies."

Product Development Update

PTG-300: Injectable Hepcidin Mimetic for Blood Disorders

• The Company is conducting Phase 2 proof of concept studies with PTG-300 in patients with beta-thalassemia, polycythemia vera and hereditary hemochromatosis.
• In December 2019, the Company reported observations of dose-related reductions from high baseline serum iron and transferrin saturation (TSAT) levels in the ongoing open-label TRANSCEND Phase 2 study of PTG-300, supporting continued evaluation with additional dose regimens and longer follow-up time periods.
• An investigator-sponsored study of PTG-300 in patients with myelodysplastic syndromes, a fourth potential indication for PTG-300, is expected to begin in the first half of 2020.

PTG-200 (JNJ-67864238): Oral IL-23 Receptor Antagonist for Inflammatory Bowel Disease

• Protagonist Therapeutics and Janssen Biotech are jointly conducting the development of PTG-200 (or JNJ-67864238) through completion of a Phase 2a study in patients with moderate-to-severe Crohn's disease, with the anticipation of completion in the first half of 2021.
• Protagonist achieved milestones leading to payments from Janssen Biotech of $25 million received in 2019 triggered by the decision to advance PTG-200 in a Phase 2a study and expansion of the existing collaboration agreement, and $5 million received in early 2020 on the nomination of a second-generation oral IL-23 receptor antagonist.

PN-943:Oral Alpha-4-Beta-7 Integrin Antagonist for Inflammatory Bowel Disease

• Results from a Phase 1 study of PN-943 demonstrated a sustained and superior target engagement as compared with the first-generation oral alpha-4-beta-7 integrin antagonist PTG-100. These results were highlighted in an oral presentation at the 2019 Digestive Disease Week conference.
• The Company plans to initiate a Phase 2 study in patients with ulcerative colitis in the second quarter of 2020, with topline data expected in the second half of 2021.
• Preclinical research findings on PN-943 were presented on February 14, 2020, at the 15th Congress of the European Crohn's and Colitis Organization (ECCO) in Vienna.
• Preclinical research findings for PN-943 have been accepted for presentation at the 2020 Digestive Disease Week conference taking place May 2-5, 2020, in Chicago.

Financial Results

• Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities as of December 31, 2019 were $133.0 million. The Company expects current cash, cash equivalents and marketable securities and access to its debt facility to be sufficient to fund its planned operating and capital expenditures through year-end 2021.
• License and Collaboration Revenue: License and collaboration revenue of $2.7 million for the fourth quarter of 2019 was in line with $2.4 million for the same period of 2018. License and collaboration revenue for the full year 2019 was $0.2 million, compared to $30.9 million for 2018. The Company recognized $9.6 million of license and collaboration revenue for the full year 2019, which was offset by the one-time cumulative adjustment related to the application of revenue recognition principles following the May 2019 amendment of the Janssen Biotech collaboration agreement that reduced the revenue by $9.4 million for the year, resulting in net revenue recognition of $0.2 million for the full year 2019.
• Research and Development ("R&D") Expenses: R&D expenses for the fourth quarter and full year 2019 were $15.9 million and $65.0 million, respectively, as compared to $14.2 million and $59.5 million, respectively, for the same periods of 2018. The increases were primarily due to increased clinical development costs related to PTG-300 and PN-943, offset in part by lower clinical development costs related to PTG-200 and PTG-100.
• General and Administrative ("G&A") Expenses: G&A expenses for the fourth quarter and full year 2019 were $4.1 million and $15.7 million, respectively, as compared to $3.5 million and $13.7 million, respectively, for the same periods of 2018. The increases were primarily due to increases in salaries and employee-related expenses driven by increased headcount and professional services to support the growth in our operations.
• Net Loss: The fourth quarter net loss was $17.5 million, or a net loss of $0.63 per share, and the full year 2019 net loss was $77.2 million, or a net loss of $2.98 per share.
