Pathalys Pharma, Inc. Launches with Mission to Address High Priority Needs in Chronic Kidney Disease

– Company Acquires License to EA Pharma’s Upacicalcet Worldwide Outside of Japan and Asia

– Industry Veteran Neal Fowler Named Chief Executive Officer of New Venture

RESEARCH TRIANGLE PARK, N.C., March 1, 2022 – Pathalys Pharma, Inc., a private, late-stage biopharma company committed to the development and commercialization of a range of best-in-class therapies for patients with chronic kidney disease (CKD), today announced its formation made possible through initial seed financing from DaVita Venture Group, part of DaVita Inc. (NYSE: DVA), and Catalys Pacific. Pathalys launches with a novel clinical-stage asset, upacicalcet, that was acquired through a license granted by EA Pharma for exclusive rights to the development and commercialization of the product, worldwide outside of Japan and Asia.

“We are excited about this opportunity to join forces with DaVita, a recognized leader in kidney care, in an effort to advance multiple best-in-class therapies for patients with CKD who are in need of better treatments – beginning with upacicalcet,” said BT Slingsby, M.D., Ph.D., M.P.H., founder and Executive Chairman of Pathalys and Managing Partner, Catalys Pacific.

Upacicalcet is an intravenously administered investigational small molecule calcimimetic that may control intact parathyroid hormone (iPTH) levels in patients with secondary hyperparathyroidism (SHPT) receiving hemodialysis (HD). Upacicalcet was granted Marketing Authorization in Japan in 2021, under the brand name UPASITA®, based on a phase 3, 24-week double-blind, placebo-controlled dose-titration study and a second phase 3, 52-week open-label, dose-titration study. In these studies, upacicalcet was shown to significantly reduce iPTH and maintain long-term iPTH suppression, as well as demonstrate the potential for fewer adverse events (AEs) than currently available therapies.

In anticipation of a submission to the U.S. Food and Drug Administration (FDA), Pathalys intends to conduct two identical phase 3 clinical trials designed as randomized, double-blind, placebo-controlled studies with 27-week individualized dose titration periods in patients with SHPT due to end-stage kidney disease (ESKD) on maintenance HD.

“DaVita’s support of Pathalys Pharma underscores our commitment to bringing to market innovations that may help improve the health and quality of life of kidney care patients,” said Mahesh Krishnan, M.D., M.PH., M.B.A., F.A.S.N., Pathalys director, and Group Vice President of Research and Development at DaVita. “By combining the unique development strengths of Catalys Pacific with DaVita’s kidney care expertise, we believe Pathalys can be a platform for delivering a range of novel products and solutions that help improve patient lives.”

Chief Executive Officer and Board Appointments
Joining BT Slingsby and Mahesh Krishnan on the Pathalys Board of Directors are Jay Shepard, Pathalys co-founder and Venture Partner at Catalys Pacific; and Takeshi Takahashi, M.B.A., Pathalys co-founder and Managing Partner at Catalys Pacific.

Additionally, Neal Fowler, a seasoned industry veteran and former Chief Executive Officer (CEO) at Liquidia Corporation (NASDAQ: LQDA) has been appointed CEO at Pathalys and will serve on the company’s board of directors.

BT Slingsby continued, “We are very pleased to welcome Neal to Pathalys as CEO and member of the Pathalys Board of Directors. Neal is a proven business leader with significant experience and success in the biopharmaceutical industry and at all stages of a company’s life cycle. We are delighted to have a leader of his caliber and unwavering commitment to success lead this new venture.”

While at Liquidia, Mr. Fowler also co-founded and served as CEO of Envisia Therapeutics (acquired), an ophthalmology therapeutics company. Prior to Liquidia, Neal worked for seven years with Johnson & Johnson (NYSE: JNJ), serving as President of Centocor, Inc., a global multi-billion-dollar subsidiary focused on biomedicines, and President of Ortho-McNeil Neurologics, a company focused on neurological disorders. Mr. Fowler started his career with Eli Lilly and Company, working for 13 years in a variety of sales, marketing, and business development roles in both the pharmaceutical and medical device divisions. Mr. Fowler is the current chair of both NCBIO and the UNC Eshelman School of Pharmacy Foundation. He is a native of Raleigh, North Carolina and earned his B.S. degree in Pharmacy and M.B.A., both from the University of North Carolina at Chapel Hill.

“I am honored to have the opportunity to lead Pathalys, a company formed by industry leaders with a passion to improve the lives of patients living with CKD. I am very optimistic about the future of our organization and our lead asset, upacicalcet, as well as the other opportunities that exist to expand our portfolio,” said Mr. Fowler. “I look forward to announcing additional members of our Executive Team soon, and to working with them and members of the Pathalys Board of Directors to bring meaningful change to the lives of CKD patients and value to our stakeholders.”
