ProKidney Reports First Quarter 2023 Financial Results and Recent Corporate Highlights

WINSTON-SALEM, N.C., May 11, 2023 (GLOBE NEWSWIRE) -- ProKidney Corp. (Nasdaq: PROK) (“ProKidney” or the “Company”), a leading late clinical-stage cellular therapeutics company focused on chronic kidney disease (CKD), today announced financial results for the first quarter ended March 31, 2023, and provided an update on recent corporate developments.

“During the first quarter of 2023, we continued to advance the Phase 3 clinical development of REACT^® to assess its potential to delay, and possibly eliminate, the need for dialysis, and in parallel we sharpened our plans for manufacturing and organizational development as we progress toward potential commercialization,” said Dr. Tim Bertram, Chief Executive Officer of ProKidney. “Patient enrollment in proact 1 continues according to plan and we target interim data by year end 2024. In addition, we recently completed enrollment in REGEN-007 with a total of 53 subjects randomized into this open-label Phase 2 study evaluating diabetic patients with Stage 3/4 CKD who either receive bilateral REACT injections three months apart, consistent with our Phase 3 studies, or receive a single REACT injection with a second injection upon satisfying certain reinjection criteria. With enrollment complete, we continue to biopsy, treat, and monitor patients following administration of REACT, evaluating them as they progress through the 18-month follow up period. Once 007 data is sufficiently mature, we plan to conduct an interim analysis and target a preliminary data report in late 2023.”

James Coulston, Chief Financial Officer at ProKidney, added, “With approximately $464 million in cash, cash equivalents and marketable securities as of March 31^st of this year, we remain well capitalized to continue executing on our clinical, manufacturing, and strategic objectives as we approach these and other key inflection points. The consistency of the REACT clinical results achieved to date, coupled with the steady pace at which the ProKidney team has progressed REACT through development, gives us confidence in what the future holds both for the platform and the Company.”

Recent Corporate Highlights, and REACT^® Clinical Development Updates

• Completed enrollment in REGEN-007, an open-label Phase 2 study evaluating two injections of the cryopreserved REACT product administered either three months apart or after one or more re-injection triggers are met, with one injection delivered into each kidney. The Company anticipates initial data from this study in late 2023.
• Continued enrolling subjects in proact 1, a Phase 3 randomized, blinded, sham-controlled study evaluating up to two doses of REACT given three months apart, with one dose delivered into each kidney. The study’s target enrollment is 600 patients at high risk for progressing to kidney failure at sites in the U.S., UK and select other countries, with initial interim data expected by the end of 2024.
• Preparing for the initiation of patient enrollment into proact 2, a Phase 3 randomized, blinded, sham-controlled study to assess the safety and efficacy of up to two REACT injections, given three months apart, and delivered once into each kidney, for patients primarily in the EU, Latin America and Asia Pacific regions. The Company has protocol allowances in Belgium, France, Singapore, Spain and Austria and expects to commence enrollment in the second half of 2023.
• Presented three posters supporting the potential of REACT to preserve kidney function and slow the progression of chronic kidney disease at the National Kidney Foundation (NKF) Spring Clinical Meeting 2023 (SCM23).
• Presented two abstracts on patient demographics in the ongoing REGEN-007 study and the design of the proact 2 study at the World Congress of Nephrology (WCN).
• Presented data on the safety and feasibility of the Company’s image-guided injection procedure during an oral abstract session at the Society of Interventional Radiology (SIR) 2023 Annual Scientific Meeting.

First Quarter 2023 Financial Highlights

Liquidity: Cash, cash equivalents and marketable securities as of March 31, 2023, totaled $463.7 million, compared to $490.3 million on December 31, 2022.

R&D Expenses: Research and development expenses were $25.6 million for the three months ended March 31, 2023, compared to $28.5 million for the same period in 2022. The decrease of $2.9 million was driven primarily by decreases in equity-based payments offset by increases in clinical trial and cash compensation costs.

G&A Expenses: General and administrative expenses were $15.3 million for the three months ended March 31, 2023, compared to $38.0 million for the same period in 2022. The decrease of $22.7 million was primarily driven by decreases in equity-based compensation of approximately $26.0 million offset by increases in cash compensation costs as well as costs related to our operations as a public company.

Net Loss Before Noncontrolling Interest: Net loss before noncontrolling interest was $36.9 million and $67.5 million for the three months ended March 31, 2023, and 2022, respectively.

About CKD
CKD is a serious diagnosis with significant morbidity and mortality. Notably, the 5-year mortality of newly diagnosed Stage 4 CKD is higher than that of newly diagnosed non-metastatic cancer. CKD most often presents as a progressive decline in kidney function, ultimately resulting in the failure of the kidneys and the need for renal replacement therapy, such as hemodialysis or kidney transplant. One in three Americans is at risk for CKD, which currently affects approximately 75 million people in the United States and Europe and over 400 million across Asia. CKD is among the largest single expense incurred by the U.S. health care system.

⁽¹⁾ The Company analyzed the calculation of net loss per share for periods prior to the business combination with Social Capital Suvretta Holdings Corp. III (the “Business Combination”), on July 11, 2022 and determined that it resulted in values that would not be meaningful to the users of the consolidated financial statements, as the capital structure completely changed as a result of the Business Combination. Therefore, net loss per share information has not been presented for periods prior to the Business Combination.
