(NASDAQ:<a class="ticker" href="https://www.benzinga.com/quote/PROK">PROK</a>) </strong>("ProKidney" or the "Company&#34;), a leading late clinical-stage cell therapy company focused on chronic kidney disease (CKD), today announced the appointment of Greg Madison as Chief Commercial Officer. In this role, Mr. Madison will drive ProKidney's commercial strategy as the Company advances towards the potential commercialization of rilparencel.</p>  <p align="justify">"Greg is a seasoned commercial biopharma executive with a proven track record of building high-performing organizations, shaping strategy, and preparing innovative therapies for market," said Bruce Culleton, M.D., CEO of ProKidney. "He brings valuable operational and leadership skills needed to help guide ProKidney through its next phase of growth, including strong depth in nephrology and other specialty markets. As we advance our clinical and regulatory objectives for rilparencel, Greg will play a key role in strengthening our leadership team and positioning rilparencel for potential commercialization."</p>  <p align="justify">Mr. Madison brings more than two decades of executive leadership experience across commercial strategy, general management, launch planning, business development, and company building in both clinical and commercial-stage biopharmaceutical companies. Most recently, he served as Chief Executive Officer of Shield Therapeutics plc, where he redesigned the commercial strategy, identified and led a transformative business development transaction, and raised capital to position the company on a path to profitability. Previously, he was Chief Executive Officer of Melt Pharmaceuticals, creating the company and advancing a novel sublingual combination drug from preclinical to Phase 2. Prior to that, he served as President and CEO of Keryx Biopharmaceuticals, leading its evolution from a clinical to commercial-stage organization, launching a novel iron-based phosphate binder for dialysis patients, and advancing a second indication for iron deficiency anemia. Earlier in his career, Mr. Madison was Executive Vice President and Chief Commercial Officer of AMAG Pharmaceuticals, and Vice President/General Manager of the Global Renal Business at Genzyme, where he helped drive Renagel/Renvela to blockbuster status with over $1 billion in annual revenue.</p>  <p align="justify">"ProKidney is developing a truly novel cell therapy with the potential to address a profound unmet need for patients with advanced CKD and diabetes," said Greg Madison. "As a potential first cell therapy for CKD patients and nephrologists, I am excited to join the Company at such an important time. I look forward to working alongside Bruce and the broader team to shape the commercial strategy, organization, and execute the plans needed to support the potential launch of rilparencel."</p>  <p align="justify"><strong>About Chronic Kidney Disease<br></br></strong>CKD is a progressive condition characterized by the gradual decline of kidney function, which can ultimately lead to end-stage kidney disease (ESKD) requiring dialysis or transplantation. An estimated 37 million adults in the U.S. have CKD, though many remain undiagnosed in the early stages. Diabetes is the leading cause of CKD, and individuals with both conditions face significantly elevated risks of cardiovascular events, hospitalization, and mortality. ProKidney is developing rilparencel for patients with Stage 3b/4 CKD and diabetes, a population that includes over 1 million people in the U.S. While current treatment options aim to slow disease progression, there remains a substantial unmet need for therapies that can stabilize kidney function and delay or prevent the need for dialysis in patients with advanced CKD.</p>  <p align="justify"><strong>About ProKidney Corp.</strong><br></br>ProKidney, a pioneer in the treatment of CKD through innovations in cell therapy, was founded in 2015 after a decade of research. ProKidney's lead product candidate, rilparencel (also known as REACT<sup>&#xAE;</sup>), is a first-in-class, patented, proprietary autologous cell therapy with regenerative medicine advanced therapy designation that is being evaluated in the ongoing Phase 3 REGEN-006 (PROACT 1) study for its potential to preserve kidney function in patients with advanced CKD and type 2 diabetes.
