SAN DIEGO, February 28, 2023 (GLOBE NEWSWIRE) -- Prometheus Biosciences, Inc. (Nasdaq: RXDX), a clinical-stage biotechnology company pioneering a precision medicine approach for the discovery, development, and commercialization of novel therapeutics for the treatment of immune-mediated diseases, today reported financial results for the quarter and full-year ended December 31, 2022 and highlighted recent corporate progress.
"2022 was a momentous year for Prometheus and the IBD community, highlighted by the positive readout in both PRA023 Phase 2 studies in UC and CD, which we believe set a new standard in IBD by combining high efficacy and favorable safety results,” said Mark McKenna, Chairman and CEO of Prometheus Biosciences. “We continue to believe that PRA023 is a potential best-in-class and first-in-class therapeutic candidate for IBD and we intend on carrying this momentum into 2023 by advancing PRA023 into Phase 3 studies.”
FOURTH QUARTER AND FULL-YEAR 2022 AND RECENT CORPORATE HIGHLIGHTS
CORPORATE HIGHLIGHTS
Reported positive results for PRA023 in both ARTEMIS-UC Phase 2 and APOLLO-CD Phase 2a studies. Prometheus reported topline results from the initial cohort of its ARTEMIS-UC Phase 2 trial and results from its APOLLO-CD Phase 2a trial of PRA023, demonstrating strong efficacy and favorable safety results in both studies in the context of very severe and refractory patient populations. The company plans to advance to Phase 3 trials in both UC and CD this year.
Expanded therapeutic investigation of PRA023 into SSc-ILD, a rare autoimmune disorder. Prometheus initiated its third Phase 2 study of PRA023, ATHENA-SSc-ILD, targeting both key fibrotic and inflammatory pathways for the treatment of SSc-ILD. PRA023 received Fast Track Designation from the US Food and Drug Administration (FDA) for the treatment of SSc-ILD. Systemic Sclerosis (SSc) is a rare autoimmune disorder characterized by progressive fibrosis of the skin and internal organs thought to result from inflammation and chronic immune activation. Lung involvement (SSc-ILD) is the leading cause of morbidity and mortality for individuals with the disorder. SSc-ILD has been largely irreversible with current therapeutic strategies focused on slowing progression of the disorder. Topline results from the Phase 2 study are expected in 1H 2024.
Advanced second precision program, PRA052, into Phase 1. Prometheus received IND clearance from the FDA and initiated a Phase 1 trial in normal healthy volunteers (NHVs) for PRA052, a potential first-in-class monoclonal antibody blocking CD30 ligand (CD30L). CD30L is a costimulatory molecule that has been implicated in inflammatory bowel disease (IBD) by genetic, preclinical, and human translational data. Prometheus is also developing a companion diagnostic candidate designed to select potential responders for this program. Results from the Phase 1 NHV study are expected in 4Q 2023.
Completed upsized $550M public offering of common stock. Prometheus completed an upsized public offering of common stock following the release of its Phase 2 data on PRA023, with net proceeds to the company of approximately $520 million.
UPCOMING ANTICIPATED MILESTONES AND EVENTS
FOURTH QUARTER AND FULL-YEAR 2022 FINANCIAL RESULTS
Cash, Cash Equivalents and Short-Term Investments. As of December 31, 2022, Prometheus had cash, cash equivalents and short-term investments of $695.8 million, compared to $257.3 million at the end of 2021. The increase is primarily due to raising approximately $470.5 million in net proceeds through an upsized underwritten public offering of common stock in Q4 2022. Subsequent to the end of the year, Prometheus raised approximately $50.1 million in additional net proceeds through the exercise of the underwriters’ option to purchase additional shares.
Collaboration Revenue. Revenue was $0.7 million for the three months ended December 31, 2022, compared to $1.0 million for the three months ended December 31, 2021 and $6.8 million for the full year 2022 compared with $3.1 million for the full year 2021. The fluctuations were primarily due to revenue generated from Prometheus’ collaboration with Dr. Falk Pharma GmbH.
Research and Development (R&D) Expenses. Research and development expenses were $29.9 million for the three months ended December 31, 2022 compared to $23.6 million for the three months ended December 31, 2021 and $112.8 million for the full year 2022 compared with $62.4 million for the full year 2021. The increases in R&D expenses were primarily due to advancement of PRA023 in global Phase 2 clinical trials and PRA052 into Phase 1 clinical trials, as well as advancing our other development programs.
General and Administrative (G&A) Expenses. General and administrative expenses were $12.0 million for the three months ended December 31, 2022 compared to $7.4 million for the three months ended December 31, 2021 and $39.7 million for the full year 2022 compared with $28.5 million for the full year 2021. The increases were primarily due to an increase in headcount and stock-based compensation expense.
