NEWARK, Calif., Nov. 3, 2021 /PRNewswire/ -- Protagonist Therapeutics, Inc. (Nasdaq: PTGX) ("Protagonist" or "the Company") today reported its financial results for the third quarter ended September 30, 2021 and provided a corporate update.

"We are excited to share the substantial progress made thus far in all of our clinical programs, highlighted by the presentation of proof-of-concept data on rusfertide in hereditary hemochromatosis at the upcoming AASLD meeting, and the new rusfertide data in polycythemia vera, which will be presented by the year's end," said Dinesh V. Patel, Ph.D., President and Chief Executive Officer. "We were very pleased that the FDA reached a swift resolution regarding the clinical hold placed on rusfertide, and we are in the process of resuming all rusfertide clinical studies. Additionally, we are highly encouraged with the rate of enrollment in the Phase 2 study of our oral alpha-4-beta-7 integrin antagonist PN-943, for ulcerative colitis, an indication with a large patient population and unmet treatment need. We maintain our guidance of a data readout in Q2 2022, and in anticipation of this, we are excited that Dr. Scott Plevy has joined our team as Executive Vice President and Therapeutic Head, Gastroenterology. As a renowned gastroenterologist, Dr. Plevy will oversee the clinical development of PN-943 and other future programs focused on gastrointestinal diseases. Finally, our oral IL-23 receptor antagonist program, in partnership with Janssen, continues to make demonstrated progress, with PN-235 now advancing into a Phase 2 study in psoriasis in early 2022."

Third Quarter 2021 Recent Developments and Upcoming Milestones

Rusfertide: Subcutaneous Injectable Hepcidin Mimetic for Polycythemia Vera (PV) and Other Blood Disorders

• On October 11, 2021, Protagonist announced that the U.S. Food and Drug Administration (FDA) removed the full clinical hold on rusfertide's clinical studies after the Company provided the FDA with all requested information, including the individual patient clinical safety reports, updated the investigator brochure and patient informed consent forms, conducted a comprehensive review of the most recent safety database, and added new safety and stopping rules in the study protocols. This was in response to the Company receiving a communication from the FDA that Protagonist's clinical studies for rusfertide had been placed on clinical hold on September 17, 2021. Protagonist has been working closely with study investigators and clinical trial sites to resume enrollment and dosing of patients in ongoing clinical trials with rusfertide.
• An abstract highlighting new, preliminary data from a Phase 2 proof-of-concept study in hereditary hemochromatosis (HH) has been selected for oral presentation by Dr. Kris Kowdley, from the Liver Institute Northwest in Seattle. These data will be presented on November 13, 2021 at The Liver Meeting® 2021, hosted by the American Association for the Study of Liver Diseases (AASLD).
• The Company intends to report updated data from the Phase 2 study of rusfertide in polycythemia vera (PV) by the end of 2021.
• The Company is on track to initiate the Phase 3 study of rusfertide in PV in Q1 2022.
• The Company resolved its collaboration agreement dispute with Zealand Pharma, reducing future development and sales milestone payments and royalties owed to Zealand for rusfertide under the companies' 2012 collaboration agreement. Under the new terms of the agreement, future development and sales milestone payments (other than $2.5 million in near-term milestones) and royalties for rusfertide have been reduced by 50 percent. Milestones and royalty payments will be due for sales and milestones achieved by either Protagonist or any future rusfertide licensee or partner. Protagonist will also make a $1.5 million payment to Zealand in August 2022.

PN-943: Oral, gut-restricted, alpha-4-Beta-7 Integrin Antagonist for Ulcerative Colitis

• We are continuing to see steady progress in the enrollment and execution of the Phase 2 IDEAL study of PN-943 in ulcerative colitis. This study includes a 12-week induction period and a 40-week open label extension. Topline data from the 12-week induction period is expected in the second quarter of 2022.
• Scott Plevy, M.D., renowned expert in translational and clinical research in gastroenterology and immunology, was appointed Executive Vice President and Therapeutic Head, Gastroenterology, and he will oversee clinical operations and development of Protagonist's ongoing and future programs in gastrointestinal diseases, including PN-943.

Oral IL-23 Receptor Antagonists (collaboration between Janssen Biotech, Inc. and Protagonist)

• Following a pre-specified interim analysis criteria, a portfolio decision was made to stop further development of the first-generation IL-23 receptor antagonist (IL-23R) candidate PTG-200 (JNJ-67864238), in favor of continued development of the two second generation candidates PN-235 (JNJ-77242113) and PN-232 (JNJ-75105186) with superior product profiles. In particular:
• The Phase 1 study of PN-235 is completed, and a Phase 2 study in psoriasis is anticipated to initiate in early 2022.
• The Phase 1 study with PN-232 is under progress with study completion expected by mid-2022.
• Additional development in IBD is expected to initiate in 2022.
• Protagonist will earn a $25 million milestone in connection with the initiation of the first Phase 2 study of a second-generation candidate, and a $10 million milestone in connection with the initiation of the second Phase 2 study of a second-generation candidate. Protagonist remains eligible for up to approximately $900 million in development-related milestone payments, in addition to the $87.5M in milestones already earned.
• Protagonist received a $7.5 million milestone payment from Janssen, triggered by the completion of the clinical data collection Phase 1 activities for PN-235 (JNJ-2113).

Third Quarter 2021 Financial Results

• Cash, Cash Equivalents and Marketable Securities: Cash, cash equivalents and marketable securities as of September 30, 2021, were $352.5 million. The Company expects current cash, cash equivalents and marketable securities to be sufficient to fund its planned operating and capital expenditures through 2024.

• License and Collaboration Revenue: License and collaboration revenues were $10.3 million and $18.7 million for the three and nine months ended September 30, 2021, respectively, as compared to $13.1 million and $23.0 million reported for the same periods of 2020. The Company recognized $8.0 million as a cumulative catch-up amount during the three months ended September 30, 2021, following the amendment of its collaboration agreement for the development of IL-23 receptor antagonist assets with Janssen Biotech. This cumulative catch-up was primarily the result of an acceleration of our cumulative performance completed under our obligation, following the amendment to the collaboration which reduced the remaining services the Company is responsible to conduct. We are nearing completion of our remaining services to be provided to Janssen under the collaboration, in particular, both the ongoing Phase 1 trials in PN-235 and PN-232, are expected to be complete in the fourth quarter of 2021 and second quarter 2022, respectively. Revenue for the prior year's third quarter of 2020 also included an estimate update for services completed versus remaining services to be performed under the Janssen collaboration agreement which accelerated revenue recognition.

• Research and Development ("R&D") Expenses: R&D expenses for the three and nine months ended September 30, 2021, were $37.0 million and $87.6 million, respectively, as compared to $16.0 million and $55.0 million, respectively, for the same periods of 2020. The increases were primarily due to additional costs associated to advancing our clinical trials with our pipeline assets rusfertide and PN-943, as well as our second-generation IL-23 receptor antagonist assets under the Janssen collaboration (PN-235 and PN-232). The increases also relate to higher research spending and employee related costs, including stock-based compensation expenses following recent hiring in support of our advancing research and development programs. Following the amendment to the Zealand collaboration agreement we also recorded $4.0 million in the quarter ended September 30, 2021 in R&D expense related to these collaboration payments.

• General and Administrative ("G&A") Expenses: G&A expenses for the three and nine months ended September 30, 2021, were $7.3 million and $19.9 million, respectively, as compared to $4.9 million and $13.6 million for the same periods of 2020. The increases were primarily related to professional fees, insurance costs and employee compensation related expenses, including stock-based compensation expenses, supporting the growth in our operations.

• Stock Based Compensation ("SBC") Expenses: SBC expenses for the three and nine months ended September 30, 2021, were $4.8 million and $11.4 million, respectively, as compared to $1.8 million and $5.9 million, respectively, for the same periods of 2020. SBC increases included in R&D and G&A expenses are primarily attributable to the addition of new employees and related stock grants in support of the Company's continued growth coupled with the increase in the Company's stock price at grant date which is used in the SBC expense calculation.

• Net Loss: The third quarter 2021 net loss was $33.8 million, or a net loss of $0.70 per share, and the nine months ended September 30, 2021, net loss was $88.6 million, or a net loss of $1.94 per share, compared to the third quarter of 2020 net loss of $7.8 million, or a net loss of $0.21 per share, and the nine months ended September 30, 2020, net loss of $47.3 million, or a net loss of $1.45 per share.
