SAN DIEGO, May 13, 2021 (GLOBE NEWSWIRE) -- Prometheus Biosciences, Inc. (Nasdaq: RXDX), a biotechnology company pioneering a precision medicine approach for the discovery, development, and commercialization of novel therapeutic and companion diagnostic products for the treatment of immune-mediated diseases, starting first with inflammatory bowel disease (IBD), today reported financial results for the quarter ended March 31, 2021 and highlighted recent corporate progress.
“2021 is shaping up to be a transformational year for Prometheus with the successful completion of our IPO and planned advancement of our lead program, PRA023, into a Phase 2 Ulcerative Colitis (UC) trial and a Phase 2a Crohn’s Disease (CD) trial in the third quarter,” said Mark McKenna, President and CEO of Prometheus. “This will be the first trial in the IBD space that will utilize a precision medicine approach with a novel mechanism of action designed to address both inflammation and fibrosis, which we believe is important to drive clinically meaningful outcomes for patients.”
First Quarter 2021 and Recent Corporate Highlights
Launched Prometheus Enroll360™ to accelerate patient recruitment. Prometheus’ Enroll360™ is a global patient recruitment platform that is designed to accelerate development timelines by improving the efficiency of patient identification and increasing the rate of enrollment for its biomarker-guided clinical trials. Prometheus is building a global network of trial-ready sites where over 5,000 patients will be molecularly profiled and clinically characterized to determine their eligibility for Prometheus clinical trials. The company plans to utilize Enroll360™ in Prometheus’ companion diagnostic-paired clinical trials for PRA023 as well as future programs.
Expanded precision medicine pipeline with new programs for IBD
- PR1100 targets a pro-inflammatory cytokine receptor associated with several auto-immune diseases, with multiple Crohn’s disease-associated SNPs identified in the gene locus of this target, and other members of this signaling pathway
- PR1800 targets a chemo-attractant factor which contributes to the local accumulation of a defined inflammatory effector cell population in the GI tract
- PR2100 targets a cytokine implicated in a range of inflammatory and fibrotic diseases. In IBD specifically, this cytokine has been implicated to contribute to non-response to anti-TNF therapies
Strengthened leadership and Board of Directors. Prometheus appointed commercial veteran Mark Stenhouse as Chief Operating Officer, Chris Doughty as Chief Business Officer, and Nori Ebersole as Chief People Officer to the Company and appointed experienced biotech leaders Helen C. Adams, CPA, Judith Swain, MD, and Mary Szela to its Board of Directors.
Completed initial public offering. On March 16, 2021, the company completed its IPO issuing 11,500,000 shares of common stock, which included the full exercise by the underwriters of their option to purchase 1,500,000 additional shares, at $19.00 per share resulting in gross proceeds of $218.5 million, before deducting underwriting discounts and commissions and other offering expenses.
Upcoming Milestones and Events
- Initiation of Phase 2 UC trial and Phase 2a CD trial of PRA023 expected in 3Q 2021
- R&D day planned for 3Q 2021 to discuss TL1A mechanism and PRA023 Phase 2 study designs
- Final Phase 1a trial results of PRA023 expected in 4Q 2021
First Quarter 2021 Financial Results
Cash and Cash Equivalents. As of March 31, 2021, Prometheus Biosciences had cash and cash equivalents of $311.2 million, compared to $54.2 million at the end of 2020. We received net proceeds of $199.8 million from the sale of our common stock in our IPO, and net proceeds of $73.7 million from the sale of shares of our Series D-2 convertible preferred stock.
Collaboration Revenue. Revenue was $0.8 million for the three months ended March 31, 2021 compared to $0.2 million for the three months ended March 31, 2020 due to additional revenue generated from Prometheus’ partnership with Dr. Falk Pharma.
Research and Development (R&D) Expenses. Research and development expenses were $7.8 million for the three months ended March 31, 2021 compared to $4.3 million for the three months ended March 31, 2020. The increase of $3.5 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily driven by a $3.0 million increase in expenses related to research and development expenses for our product candidates and a $0.5 million increase in expenses related to personnel costs due to increased headcount to support increased development activities.
General and Administrative (G&A) Expenses. General and administrative expenses were $5.2 million for the three months ended March 31, 2021 compared to $2.4 million for the three months ended March 31, 2020. The increase of $2.8 million for the three months ended March 31, 2021 compared to the three months ended March 31, 2020 was primarily driven by one-time transaction costs related to our IPO of $1.8 million with the remainder due to increases in corporate personnel costs due to the expansion of our executive team.
PRA023 is an IgG1 humanized monoclonal antibody (mAb) that has been shown to block tumor necrosis factor (TNF)-like ligand 1A (TL1A). PRA023 binds both soluble and membrane-associated human TL1A with high affinity and specificity and has the potential to substantially improve outcomes for moderate-to-severe IBD patients predisposed to increased TL1A expression. Prometheus is developing PRA023 for the treatment of Ulcerative Colitis (UC) and Crohn’s Disease (CD) and initiated a Phase 1a clinical trial in normal healthy volunteers in December 2020. The Company is also developing a genetic-based companion diagnostic to identify patients who are predisposed to increased expression of TL1A and therefore potentially more likely to respond to PRA023.
