Unicycive Therapeutics Announces Submission of the New Drug Application (NDA) to the U.S. FDA for Oxylanthanum Carbonate (OLC) for the Treatment of Hyperphosphatemia in Patients with Chronic Kidney Disease on Dialysis

LOS ALTOS, Calif., Sept. 03, 2024 (GLOBE NEWSWIRE) -- Unicycive Therapeutics, Inc. (Nasdaq: UNCY), a clinical-stage biotechnology company developing therapies for patients with kidney disease (the “Company” or “Unicycive”), today announced that the Company has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for Oxylanthanum Carbonate (OLC) for the treatment of hyperphosphatemia in patients with chronic kidney disease (CKD) on dialysis. Unicycive is seeking FDA approval of OLC via the 505(b)(2) regulatory pathway.

“With this NDA submission, we are excited to be one step closer to our goal of bringing OLC to patients with chronic kidney disease who are living with hyperphosphatemia,” said Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “We believe our data support a differentiated and best-in-class therapy that will maintain phosphate control while reducing the onerous pill burden patients currently have to manage. Over the last several months, our team has worked diligently to reach this milestone, and we are now preparing to launch OLC, if approved. We are also pleased to report that the FDA granted a waiver for the NDA application Prescription Drug User Fee Act (PDUFA) fees which is a significant savings of approximately $4 million.”

The NDA submission package is based on data from three clinical studies (a Phase 1 study in healthy volunteers, a bioequivalence study in healthy volunteers, and a tolerability study of OLC in CKD patients on dialysis), multiple preclinical studies, and the specifications and practices related to chemistry, manufacturing and controls (CMC).

About Oxylanthanum Carbonate (OLC)

Oxylanthanum carbonate is a next-generation lanthanum-based phosphate binding agent utilizing proprietary nanoparticle technology being developed for the treatment of hyperphosphatemia in patients with chronic kidney disease (CKD) on dialysis. OLC has over forty issued and granted patents globally. Its potential best-in-class profile may have meaningful patient adherence benefits over currently available treatment options as it requires a lower pill burden for patients in terms of number and size of pills per dose that are swallowed instead of chewed. Based on a survey conducted in 2022, Nephrologists stated that the greatest unmet need in the treatment of hyperphosphatemia with phosphate binders is a lower pill burden and better patient compliance.¹ The global market opportunity for treating hyperphosphatemia is expected to exceed $2.5 billion, with the United States accounting for more than $1 billion of that total². Despite the availability of several FDA-cleared medications, 75 percent of U.S. dialysis patients fail to achieve the target phosphorus levels recommended by published medical guidelines.

About Hyperphosphatemia

Hyperphosphatemia is a serious medical condition that occurs in nearly all patients with End Stage Renal Disease (ESRD). If left untreated, hyperphosphatemia leads to secondary hyperparathyroidism (SHPT), which then results in renal osteodystrophy (a condition similar to osteoporosis and associated with significant bone disease, fractures and bone pain); cardiovascular disease with associated hardening of arteries and atherosclerosis (due to deposition of excess calcium-phosphorus complexes in soft tissue). Importantly, hyperphosphatemia is independently associated with increased mortality for patients with chronic kidney disease on dialysis. Based on available clinical data to date, over 80% of patients show signs of cardiovascular calcification by the time they become dependent on dialysis.

Dialysis patients are already at an increased risk for cardiovascular disease (because of underlying diseases such as diabetes and hypertension), and hyperphosphatemia further exacerbates this. Treatment of hyperphosphatemia is aimed at lowering serum phosphate levels via two means: (1) restricting dietary phosphorus intake; and (2) using, on a daily basis, and with each meal, oral phosphate binding drugs that facilitate fecal elimination of dietary phosphate rather than its absorption from the gastrointestinal tract into the bloodstream.
