WINSTON-SALEM, N.C., May 10, 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 reported business updates and financial results for the first quarter ended March 31, 2024.

“With the full results of RMCL-002 to be presented at the European Renal Association Congress later this month and the upcoming interim readout of REGEN-007 in mid-2024, we look forward to further elucidating the effect of rilparencel in preserving kidney function in patients with type 2 diabetes and CKD,” said Bruce Culleton, Chief Executive Officer. “I believe our recent hires of Dr. Ulrich Ernst and Lucio Tozzi will prove invaluable in the execution of our planned manufacturing and Phase 3 study milestones. With our PROACT 1 protocol amendment completed and submitted to the FDA, we look forward to the resumption of the study as we focus on patients with severe CKD. Rilparencel has the potential to be meaningful in this high-risk patient population where there are limited therapeutic options for care.”

Clinical Updates

• ERA Congress in Stockholm, Sweden from May 23-26, 2024. ProKidney will present the Phase 2 RMCL-002 final results abstract titled “Rilparencel Renal Autologous Cell Therapy for Patients with Stage 3-4 CKD and Type 2 Diabetes: Results from a Phase 2 Clinical Trial” in the Late Breaking Clinical Trials session at 15:30-15:45 CEST on May 25, 2024. An investor call to provide a perspective on CKD with Dr. Arnold Silva and Dr. Steven Coca and a recap of the RMCL-002 data is planned for May 28, 2024. Further details will be provided.
• The PROACT 1 Phase 3 study (REGEN-006) protocol amendment has been completed and was submitted to the FDA in late March. This amendment updated the 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 focusing on patients with more severe CKD will better align with RMCL-002 results and feedback from payers and providers. The Company continues to expect PROACT 1 will resume enrollment, and PROACT 2 will commence enrollment, in mid-2024.

Corporate Updates

• Bank of America Securities Health Care Conference in Las Vegas, NV from May 14-16, 2024. Senior members of the management team will be participating in a fireside chat and one-on-one meetings at the upcoming conference. Interested investors should contact their Bank of America representative to schedule meetings.
• Appointment of Ulrich Ernst, Ph.D as Executive Vice President of Technical Operations. In March, the Company announced Dr. Ernst joined as EVP of Technical Operations and as part of the ProKidney Executive Leadership Team. Dr. Ernst brings over 30 years of experience in the biopharmaceutical industry with a focus on process development, manufacturing and facility oversight, and supply chain operations in the cell space. Prior to ProKidney, Dr. Ernst was Senior Vice President of Technical Operations at Iovance Biotherapeutics, Chief Operating Officer at Amunix Operating Inc., and Senior Vice President of Manufacturing Operations at Cytovance Biologics.
• Appointment of Lucio Tozzi as Senior Vice President of Global Clinical Operations. In January, Mr. Tozzi joined as SVP of Global Clinical Operations.

First Quarter 2024 Financial Highlights

Liquidity: Cash, cash equivalents and marketable securities as of March 31, 2024, totaled $329.0 million, compared to $363.0 million on March 31, 2023. We expect that our existing cash, cash equivalents and marketable securities held on March 31, 2024, 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 $27.2 million for the three months ended March 31, 2024, compared to $25.6 million for the same period in 2023. The increase of $1.6 million was driven primarily by increases in cash compensation costs of approximately $3.2 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 professional fees of approximately $2.6 million primarily related to the remediation of documentation deficiencies within our quality management systems. These increases have been partially offset by decreases in spending of approximately $2.1 million on our Phase 3 program due to the pause in enrollment as well as decreased spending on manufacturing improvements of approximately $2.5 million.

G&A Expenses: General and administrative expenses were $12.8 million for the three months ended March 31, 2024 compared to $15.3 million for the same period in 2023. The decrease of $2.4 million has been primarily driven by decreases in equity-based compensation of approximately $4.8 million, and was partially offset by increases in cash compensation and professional fees of approximately $1.7 million and $0.9 million, respectively.

Net Loss Before Noncontrolling Interest: Net loss before noncontrolling interest was $35.3 million and $36.9 million for the three months ended March 31, 2024 and 2023, respectively.

Shares outstanding: Class A and Class B ordinary shares outstanding as of March 31, 2024 totaled 229,344,883.
