ProKidney Reports Full Year 2023 Financial Results and Recent Corporate Highlights

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.

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.

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.

⁽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. The basic and diluted net loss per share attributable to Class A ordinary shareholders for the year ended December 31, 2022, represents only the period after the Business Combination to December 31, 2022.
