Unicycive to Highlight Patient Reported Outcomes Data at Upcoming Medical Meetings Showing Oxylanthanum Carbonate Reduced Pill Burden and Improved Adherence in Treatment of Hyperphosphatemia

Rhea-AI Summary

Unicycive Therapeutics (UNCY) announced the presentation of patient reported outcomes data from its pivotal UNI-OLC-201 clinical study of oxylanthanum carbonate (OLC) for treating hyperphosphatemia in chronic kidney disease patients on dialysis. The data will be presented at three major medical meetings in 2025: the Annual Dialysis Conference (March 13-16), National Kidney Foundation Spring Clinical Meetings (April 10-13), and American Nephrology Nurses Association National Symposium (May 1-4).

The company's OLC, utilizing proprietary nanoparticle technology, aims to reduce pill size and quantity for patients. The FDA has accepted OLC's New Drug Application with a PDUFA Target Action Date of June 28, 2025. Currently, hyperphosphatemia remains uncontrolled in 75% of U.S. dialysis patients due to issues with existing treatments.

The presentations will highlight how OLC reduces pill burden by half and improves treatment adherence, potentially offering a more effective solution for phosphate control in dialysis patients.

LOS ALTOS, Calif., March 13, 2025 (GLOBE NEWSWIRE) -- Unicycive Therapeutics, Inc. (Nasdaq: UNCY), a clinical-stage biotechnology company developing therapies for patients with kidney disease, today announced that it will present patient reported outcomes data from its pivotal UNI-OLC-201 clinical study characterizing the potential impact of oxylanthanum carbonate (OLC) on the treatment of hyperphosphatemia in patients with chronic kidney disease (CKD) on dialysis. These data will be presented at three medical meetings, including the 2025 Annual Dialysis Conference (ADC), March 13-16, 2025, National Kidney Foundation (NKF) Spring Clinical Meetings, April 10-13, 2025, and the 2025 American Nephrology Nurses Association (ANNA) National Symposium, being held on May 1-4, 2025.

Unicycive’s investigational drug OLC leverages proprietary nanoparticle technology to reduce the number and size of pills that patients must take. If approved, OLC may provide patients and their physicians with a welcome new option to control hyperphosphatemia. The New Drug Application (NDA) for OLC was accepted by the U.S. Food and Drug Administration (FDA) for the treatment of hyperphosphatemia in patients with chronic kidney disease on dialysis. The FDA set a Prescription Drug User Fee Act (PDUFA) Target Action Date of June 28, 2025.

“Despite the availability of several approved phosphate binders, hyperphosphatemia remains uncontrolled in 75% of people in the U.S. on dialysis due to challenges of insufficient potency, pill burden and unpalatable formulations. There is a critical need for more effective solutions,” said Shalabh Gupta, M.D., Chief Executive Officer of Unicycive. “Innovative solutions such as OLC that improve phosphate control and minimize pill size and count have the potential to significantly improve adherence, empowering those on dialysis to manage their treatment more effectively.”

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). 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 projected to be in excess of $2.28 billion, with the North America accounting for more than $1 billion of that total.² 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.³

Unicycive is seeking FDA approval of OLC via the 505(b)(2) regulatory pathway. 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 chemistry, manufacturing and controls (CMC) data. OLC is protected by a strong global patent portfolio including issued patents on composition of matter with exclusivity until 2031, and with the potential for patent term extension until 2035.

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.⁴

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.
