WINSTON-SALEM, N.C., March 21, 2024 (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 year ended December 31, 2023. “We are very excited about the future of ProKidney. Building on the positive interim Phase 2 data that we released last Fall for rilparencel (which we sometimes refer to as REACT®) demonstrating the potential to preserve kidney function in patients with type 2 diabetes mellitus and advanced kidney disease, we look forward to the REGEN-007 Phase 2 interim data readout mid-year,” said Bruce Culleton, Chief Executive Officer at ProKidney. “Our clinical data to date have shown that rilparencel may meet a current unmet medical need by preserving kidney function and delaying the onset of dialysis in high-risk patients with CKD caused by type 2 diabetes. Rilparencel has the potential to be very meaningful to this high-risk patient population where there are limited options for care outside of preparing for transplantation or dialysis.” Corporate Updates Appointment of Dr. Bruce Culleton as ProKidney CEO. In November, the Company announced Dr. Bruce Culleton assumed the role of the CEO and joined the ProKidney board of directors. Dr. Culleton joined ProKidney in July 2023 as Executive Vice President of Clinical Development and Commercialization. Dr. Culleton has dedicated his 25-year professional career to improving the health and quality of life of patients with kidney disease and held executive leadership positions at Baxter Healthcare and CVS Kidney Care, a wholly owned subsidiary of CVS Health. Appointment of Nikhil Pereira-Kamath as Chief Business Officer. As CBO, Mr. Pereira-Kamath has global responsibility for commercial strategy, defining the Company’s growth and partnering activities, and overseeing the Company’s project management, business development and investor relations, bringing with him over a decade of experience as a seasoned entrepreneur in addition to a strong foundation in finance. Mr. Periera-Kamath had previously joined ProKidney in July 2023 as Vice President of Business Development & Innovative Solutions. Prior to joining ProKidney, he was Chief Executive Officer and subsequently Chairman of the Board, a role he continues to hold, of Africa Healthcare Network (AHN), the largest independent provider of dialysis and kidney care in sub-Saharan Africa. Clinical Development Updates Reported positive interim Phase 2 RMCL-002 study data in November, demonstrating the potential of rilparencel to preserve kidney function in moderate and high-risk patients with CKD caused by type 2 diabetes. Updated data include information from 83 patients enrolled in the RMCL-002 study and demonstrated a safety profile in line with previous rilparencel Phase 1 & 2 trials, and similar to that of a kidney biopsy.As disclosed in November 2023, overall, the updated RMCL-002 data showed preservation of kidney function in several patient groups with advanced CKD caused by type 2 diabetes. Patients with Stage 4 CKD with severe albuminuria– broadly viewed to have the highest risk of kidney failure and where there remains a significant unmet clinical need– showed the most potential benefit. Full results from RMCL-002 are expected in 1H 2024.Based on these emerging results, as disclosed in November 2023, the Company is updating its ongoing PROACT 1 Phase 3 clinical study (REGEN-006) protocol to focus on patients with higher risk of kidney failure. In the PROACT 1 Phase 3 clinical study, the eGFR enrollment range will be modified from the current range of ≥20 to ≤ 50 ml/min/1.73m2 to a new range of ≥20 to ≤ 35 ml/min/1.73m2. The Company believes that this focus on the most severe patients will better align with RMCL-002 results and clinical feedback. No changes are planned for the Phase 3 trial, PROACT 2 (REGEN-016), which is currently ≥20 to ≤ 44 ml/min/1.73m2. Maintaining the eGFR enrollment range of PROACT 2, which includes the CKD Stage 3b population, will enable the Company to seek a broader commercial label. Manufacturing has been temporarily paused while ProKidney amends the PROACT 1 protocol and concurrently, in response to Qualified Person Audit, optimizes capabilities to meet EU and Global manufacturing and quality management system standards for Phase 3 studies and prepares for transition to commercial manufacturing. No safety events were responsible for this pause and the Company expects PROACT 1 will resume, and PROACT 2 will commence, enrollment in mid-2024.Interim results from the ongoing REGEN-007 Phase 2 open-label trial of rilparencel in patients with stage 3 and 4 CKD caused by type 2 diabetes is expected in mid-2024, with full Cohort 1 12 month follow up data anticipated in 1H 2025. Full Year 2023 Financial Highlights Liquidity: Cash, cash equivalents and marketable securities as of December 31, 2023, totaled $363.0 million, compared to $490.3 million on December 31, 2022. We expect that our existing cash, cash equivalents and marketable securities held at December 31, 2023, will enable us to fund our operating expenses and capital expenditure requirements into the fourth quarter of 2025. R&D Expenses: Research and development expenses were $106.7 million for the year ended December 31, 2023, compared to $82.1 million for the same period in 2022. The increase of $24.6 million was driven primarily by increases in clinical trial costs related to our Phase 3 program of approximately $16.6 million. Additionally, we have seen increases in cash and equity compensation costs of approximately $17.2 million as we continue to hire additional personnel in the areas of clinical development, quality, manufacturing, and biostatistics to support our ongoing clinical trials. Further, we have seen increases in other research and development costs of approximately $4.7 million primarily related to additional spending on manufacturing improvements, materials and professional fees. These costs have been offset by decreases in equity-based payments for services rendered by a third party in the year ended December 31, 2022. G&A Expenses: General and administrative expenses were $44.8 million for the year ended December 31, 2023 compared $70.9 million for the same period in 2022. The decrease of $26.1 million has been primarily driven by decreases of $33.0 million associated with the recognition of equity-based compensation costs in 2022 for shares sold at less than their fair value prior to the business combination Additionally, there have been decreases in costs related to equity-based compensation and costs related to the business combination that occurred in 2022. These decreases have been offset by increases in professional fees and cash compensation costs of approximately $7.3 million and $4.7 million, respectively. Net Loss Before Noncontrolling Interest: Net loss before noncontrolling interest was $135.4 million and $148.1 million for the year ended December 31, 2023 and 2022, respectively. Shares outstanding: Class A and Class B ordinary shares outstanding as of December 31, 2023 totaled 228,178,263.
