Counting Down To The OLC PDUFA Date. Unicycive reported a 1Q25 loss of $21.2 million or $(0.61) per share, consistent with our estimates. We continue to expect approval of OLC (oxylanthanum carbonate) around its PDUFA date of June 28, followed by its launch later in the year. The company had $19.8 million in cash on March 31, 2025.
OLC Reduces Pill Burden To Improve Compliance. OLC is Unicycive proprietary formulation of lanthanum carbonate. It was developed to reduce serum phosphate levels in renal dialysis patients with only two small pills per day. We expect OLC to compete against Fosrenol (from Shire), the approved formulation of lanthanum, that requires chewing 3 to 6 large pills each day. This difference makes patient compliance easier.

– Patient-reported outcomes from Phase 2 trial of oxylanthanum carbonate (OLC) demonstrate high patient satisfaction with OLC compared to their prior phosphate lowering therapy –
– Findings from a patient survey conducted in partnership with the National Kidney Foundation (NKF) showed excessive number and large size of phosphate binder pills to be top barriers to consistent medication use –
– Results to be presented in poster sessions at the NKF Spring Clinical Meetings –
LOS ALTOS, Calif., April 10, 2025 (GLOBE NEWSWIRE) — Unicycive Therapeutics, Inc. (Nasdaq: UNCY), a clinical-stage biotechnology company developing therapies for patients with kidney disease, today announced new patient-reported outcomes data from its pivotal Phase 2 study of OLC as well as from a new survey conducted by the National Kidney Foundation (NKF) with sponsorship from Unicycive. OLC is an investigational treatment for hyperphosphatemia in patients with chronic kidney disease (CKD) on dialysis. The findings will be presented today in poster sessions at the NKF Spring Clinical Meetings taking place in Boston.
OLC leverages proprietary nanoparticle technology to reduce the number and size of pills that patients must take. The U.S. Food and Drug Administration (FDA) accepted the New Drug Application (NDA) for OLC for the treatment of hyperphosphatemia in patients with CKD on dialysis and set a Prescription Drug User Fee Act (PDUFA) Target Action Date of June 28, 2025.
“As many as two out of three of patients with end-stage kidney disease undergoing dialysis don’t consistently adhere to their phosphate binder treatment; common barriers are side effects, pill burden, and unpalatable formulations,” said Dr. Pablo Pergola, MD, PhD, Research Director, Clinical Advancement Center, Renal Associates, P.A., and principal investigator for the UNI-OLC-201 trial. “These new patient-reported outcomes underscore the potential of OLC to enhance adherence, reduce treatment burden and improve patient satisfaction. OLC could be a welcome new phosphate binder choice for patients with hyperphosphatemia due to its favorable tolerability, small, easy-to-swallow size and low pill burden.”
Patient-Reported Outcomes Data Patient-reported outcomes from the open-label Phase 2 UNI-OLC-201 clinical trial compared patients’ satisfaction with their pre-trial phosphate binders versus OLC at the end of the study based on responses to a questionnaire completed by 80 patients. This research will be presented by Guru Reddy, PhD., in the poster titled “Patient-Reported Outcomes in a Pivotal Clinical Study of Hyperphosphatemia: Oxylanthanum Carbonate Reduces Pill Burden by Half and Improves Adherence” (Poster # G-018) on Thursday, April 10, from 5:15–7:30 p.m. ET.
Results:
OLC reduced pill burden by 50% – patients took a median of three tablets of OLC per day versus six tablets of phosphate binders prior to the trial.
OLC improved adherence – 70% of patients reported consistent adherence with OLC compared to 58% who reported adherence to their pre-trial phosphate binders.
OLC was preferred – 79% of patients indicated a preference for OLC versus 4% who preferred their pre-trial phosphate binder medications.
OLC improved patient satisfaction – 98% of patients agreed that OLC was easy to take versus 38% who said that about their pre-trial phosphate binder medication, and 89% reported they were satisfied with OLC treatment versus 49% who were satisfied with pre-trial phosphate binders.
Patient Survey Results In partnership with Unicycive, NKF conducted an online survey of patients undergoing dialysis to assess the top barriers to phosphate binder adherence and to better understand what treatment characteristics could improve adherence. A total of 200 patients aged 40 and older completed the online survey from February 15 to May 16, 2024. This research will be presented by Dr. Hill Gallant, PhD, RD, Associate Professor of Nutrition in the Department of Food Science and Nutrition at the University of Minnesota-Twin Cities, in a poster titled “Pill Burden and Large Tablet Size Are Key Barriers to Phosphate Binder Adherence in Dialysis Patients” (Poster # G-297) on Thursday, April 10, from 5:15-7:30 p.m. ET.
Results showed:
Forgetfulness (63%) was the primary barrier to consistent medication use followed by excessive pill number (47%) and large pill size (47%).
Additional barriers to adherence included difficulties carrying pills (45%), gastrointestinal side effects (29%), unpleasant taste (20%), social embarrassment when taking medication (13%), and cost (10%).
Patients were more likely to prefer medication regimens with fewer and smaller pills, underscoring the impact of pill burden on adherence.
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.
About Unicycive Therapeutics Unicycive Therapeutics is a biotechnology company developing novel treatments for kidney diseases. Unicycive’s lead drug candidate, oxylanthanum carbonate (OLC), is a novel investigational phosphate binding agent being developed for the treatment of hyperphosphatemia in chronic kidney disease patients on dialysis. Positive pivotal trial results were reported in June 2024 for OLC, and a New Drug Application (NDA) is under review by the U.S. Food and Drug Administration (FDA) with a Prescription Drug User Fee Act (PDUFA) Target Action Date of June 28, 2025. OLC is protected by a strong global patent portfolio including an issued patent on composition of matter with exclusivity until 2031, and with the potential patent term extension until 2035 after OLC approval. Unicycive’s second asset, UNI-494, is a patent-protected new chemical entity in clinical development for the treatment of conditions related to acute kidney injury. UNI-494 has successfully completed a Phase 1 trial. For more information, please visit Unicycive.com and follow us on LinkedIn, X, and YouTube.

FY2025 Made Significant Progress. Unicycive reported a 4Q loss of $21.7 million or $(0.20) per share and a loss of $37.8 million or $(0.56) per share for FY2024. Cash on December 31, 2024 was $26.1 million. The most significant development, in our opinion, is the June 28, 2025, PFUFA date by which the FDA is required to answer to the Oxylanthanum (OLC) NDA.
OLC Launch is expected in Late 2025. The PDUFA date of June 28, 2025, is the statutory date by which the FDA is required to answer the NDA application. We expect OLC to be approved, based on its clinical trial data showing equivalence to lanthanum (Fosrenol, from Shire) with easier dosing, better patient compliance, and more patients reaching the target range for phosphate levels. An estimated 70% of the renal dialysis patients do not have adequate phosphate control. We believe its lower pill burden and improved patient compliance will lead to better outcomes with fewer morbidity events, leading to a strong market share.

– Oxylanthanum carbonate (OLC) New Drug Application for hyperphosphatemia in chronic kidney disease patients on dialysis under review by the FDA with a PDUFA target action date of June 28, 2025
– Commercial planning in preparation for anticipated commercial launch of OLC in late 2025
LOS ALTOS, Calif., March 31, 2025 (GLOBE NEWSWIRE) — Unicycive Therapeutics, Inc. (Nasdaq: UNCY), a clinical-stage biotechnology company developing therapies for patients with kidney disease, today announced its financial results for the full year ended December 31, 2024, and provided a business update.
“2025 is positioned to be a transformational year for Unicycive, with the near-term potential for FDA approval and commercial launch of oxylanthanum carbonate (OLC),” said Shalabh Gupta, M.D., Chief Executive Officer of Unicycive. “For approximately 75% of people in the U.S. with chronic kidney disease (CKD) on dialysis, hyperphosphatemia remains uncontrolled because of challenges with currently available phosphate binders, potentially increasing their risk of hospitalization and mortality. If approved, we believe OLC is positioned to be an important new option for these patients, distinguished by its high potency and a low pill burden. We continue to actively prepare to launch OLC, including educating key stakeholders on existing OLC data and preparing our commercial infrastructure to rapidly make OLC available to patients upon approval.”
Key Highlights & Upcoming Milestones
Announced the acceptance of the New Drug Application (NDA) by the U.S. Food and Drug Administration (FDA) for OLC for the treatment of hyperphosphatemia in patients with CKD on dialysis. The FDA set a Prescription Drug User Fee Act (PDUFA) target action date of June 28, 2025.
Unicycive’s partner in the Republic of Korea, Lotus Pharmaceutical, submitted an NDA for OLC with the Ministry of Food and Drug Safety and anticipates an application decision in June of 2026. Unicycive has an exclusive license agreement with Lotus Pharmaceutical for the development, registration, and commercialization of OLC in the Republic of Korea and has the potential to receive up to $3.7 million in milestone payments and tiered royalties based on regulatory and commercial achievements.
Continued efforts to establish an efficient commercial infrastructure, including building key functions, engaging directly with prescribers and other stakeholders and preparing to support market access are ongoing. Expanded awareness of OLC and its potential to address significant needs for CKD patients through publication of data, including in the peer-reviewed journals Clinical Therapeutics, Clinical and Translational Science, and Journal of Nephrological Science; and late-breaker presentation at the American Society of Nephrology (ASN) Kidney Week 2024. These data included clinical, preclinical and patient survey/literature review data that highlighted OLC’s favorable safety and tolerability profile, efficacy in controlling serum phosphate levels, and the need for new options to overcome the current limitations of phosphate binders and their effects on patients’ quality of life. The data also demonstrated OLC’s bioequivalence to approved lanthanum carbonate chewable tablets, and the potential benefits of combination treatment of OLC and tenapanor on phosphate management.
Successfully completed Phase 1 study of UNI-494 in healthy volunteers, which demonstrated favorable tolerability, with fast absorption and rapid metabolization. Data from the Phase 1 study and supportive preclinical data were presented at ASN 2024 and published in EC Pharmacology and Toxicology.
Financial Results for the Year Ended December 31, 2024
Licensing revenues decreased approximately $0.7 million, from the year ended December 31, 2023 due to an upfront payment of approximately $0.7 million associated with a licensing agreement entered into with Lotus International Pte Ltd. in February 2023. There was no comparable revenue earned in the current period.
Research and Development (R&D) expenses were $20.0 million for the year ended December 31, 2024, compared to $12.9 million for the same period in 2023. The increase in research and development expenses was primarily due to an increase in drug development and labor costs.
General and Administrative (G&A) expenses were $12.1 million for the year ended December 31, 2024, compared to $8.5 million for the same period in 2023. The increase was primarily due to an increase in labor, consulting and professional services costs.
Other Income was $4.6 million for the year ended December 31, 2024 compared to $9.8 million in the same period in 2023 due primarily to a decrease in the fair value of our warrant liability.
Net loss attributable to common stockholders for the year ended December 31, 2024 was $37.8 million, or $0.56 per share of common stock, compared to a net loss attributable to common stockholders of $31.4 million, or $1.28 per share of common stock for the same period in 2023. The increased net loss for the year ended December 31, 2024 was attributable primarily to an increase in drug development costs.
As of December 31, 2024, cash and cash equivalents totaled $26.1 million. The Company believes that it has sufficient resources to fund planned operations into 2026.

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.

Pre-Clinical Study Shows Synergy With Tenapanor. Unicycive Therapeutics announced the results of an animal model study that tested its phosphate binder, OLC, or oxylanthanum carbonate, and tenapanor, a phosphate-control drug that works through a different mechanism than the phosphate binding drugs. The results showed OLC had a greater reduction than tenapanor, and the combination of both drugs given together had synergistic effects that were better than either drug given alone.
Study Design. Tenapanor (Xphozah, from Ardelyx) is a sodium/hydrogen exchanger 3 (NHE3) inhibitor that works through paracellular absorption. It is used in patients that do not respond to phosphate binders or do not tolerate them. The study, “Combination Oxylanthanum Carbonate and Tenapanor Lowers Urinary Phosphate Excretion in Rats,” was published in the American Nephrology Society’s journal Kidney360. It compared the two drugs against a control (delivery vehicle alone) in rats receiving a high phosphorus diet.

Combination therapy with oxylanthanum carbonate plus tenapanor led to greater reductions in urinary phosphate excretion than either drug alone
LOS ALTOS, Calif., Feb. 20, 2025 (GLOBE NEWSWIRE) — Unicycive Therapeutics, Inc. (Nasdaq: UNCY), a clinical-stage biotechnology company developing therapies for patients with kidney disease, today announced the publication of preclinical data describing the benefits of combination treatment of oxylanthanum carbonate (OLC) and tenapanor on phosphate management in the American Society of Nephrology (ASN) journal, Kidney360.
The publication, entitled “Combination Oxylanthanum Carbonate and Tenapanor Lowers Urinary Phosphate Excretion in Rats,” examines the potential synergistic benefits of a combination of OLC, a phosphate binder, with tenapanor, a sodium/hydrogen exchanger 3 (NHE3) inhibitor, on urinary phosphate excretion. Data demonstrated sizeable reductions in urinary phosphate excretion (a proxy for intestinal phosphate absorption) in response to both OLC monotherapy and the combination of OLC with tenapanor.
“With approximately 75% of patients receiving maintenance dialysis failing to meet serum phosphate targets set by international Kidney Disease Improving Global Outcomes (KDIGO) guidelines, we must explore new approaches to improve control of hyperphosphatemia” said Glenn M. Chertow, M.D., M.P.H., Professor of Medicine, Stanford University School of Medicine. “Based on the results of this pre-clinical study, we believe that OLC, an investigational phosphate binder, when used alone or in combination with tenapanor, could improve control of hyperphosphatemia in patients receiving maintenance dialysis who are either unresponsive to currently available phosphate binders or intolerant to their associated adverse effects, high pill burden, and poor palatability.”
“We’re excited by these preclinical data showing a synergistic treatment effect from the combination of OLC and tenapanor. OLC, with its low pill burden and more palatable formulation, could complement tenapanor, significantly enhancing patient adherence and clinical outcomes,” said Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “Further studies in patients with end-stage kidney disease and hyperphosphatemia will be required to understand the most effective and best tolerated OLC-containing regimens, as we aim to improve long-term control of hyperphosphatemia and prevent its myriad complications.”
Key Findings:
Treatment with tenapanor alone (0.15 mg/kg) led to 12.5% lower mean urinary phosphate excretion compared to the vehicle in rats fed a high phosphorus diet.
A pooled analysis of monotherapy with OLC (0.75%, 1.5%, and 3%) demonstrated a 17.7% reduction in urinary phosphate excretion compared to vehicle.
Treatment with tenapanor in combination with OLC demonstrated a more pronounced 41.3% reduction in urinary phosphate excretion compared to vehicle.
The combination of OLC and tenapanor was synergistic and statistically significant (p=0.009 for 0.75% OLC + tenapanor and p=0.010 for 1.5% OLC + tenapanor).

Large pill size, high pill burden and palatability were identified as key barriers for phosphate binder adherence
LOS ALTOS, Calif., Jan. 28, 2025 (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 the publication of a review on patient perspectives regarding phosphate management in the peer-reviewed journal, Journal of Nephrological Science.
The publication, entitled “Patient Perspectives: The Effects of Contemporary Phosphorus Management on Quality of Life,” examines the challenges of phosphate management therapies from patients’ viewpoints, focusing on the limitations of current phosphate binders and their effect on patients’ quality of life. The publication underscores key findings from patient surveys and medical literature, identifying critical barriers to effective phosphorus management and emphasizing the need for patient-centered approaches to improve clinical outcomes and patient satisfaction.
“In therapeutic categories with significant patient non-adherence to standard of care like chronic kidney disease (CKD), it is essential to understand the factors disrupting medical intervention in order to offer physicians and patients innovative solutions,” said Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “We believe products like Oxylanthanum Carbonate (OLC), which is characterized by small pill size, lower pill burden, and easy-to-swallow tablets, have the potential to address many of the inherent challenges in phosphorus management that often lead to nonadherence and poor serum phosphate control. If approved, we look forward to offering OLC to CKD patients on dialysis with hyperphosphatemia.”
Key Findings:
Hyperphosphatemia is linked to increased mortality risk.
Dialysis patients often face a high daily pill burden, with phosphate binders making up about 50% of the total.
Nonadherence to phosphate binders is a significant challenge contributing to elevated phosphate levels. Studies show non-adherence rates range from 22% to 74%, with a mean non-adherence rate of 51%.
Factors contributing to non-adherence include large pill size, high pill burden, and unpleasant gastrointestinal side effects. Social factors and timing complexities also impact adherence.
Engaging patients in discussions about different phosphate binders and their unique characteristics is key to improving adherence and satisfaction. New therapies that reduce pill size or burden while maintaining efficacy could enhance clinical outcomes, quality of life, and the patient-clinician relationship.

LOS ALTOS, Calif., Jan. 07, 2025 (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 data from the Company’s oxylanthanum carbonate (OLC) Phase 1 dose escalation study in healthy volunteers was published in the peer-reviewed journal, Clinical and Translational Science.
The publication, entitled “Safety and Phosphate-Binding Capacity of Oxylanthanum Carbonate in Healthy Volunteers,” described a study evaluating the safety of escalating doses of OLC (500 mg, 1,000 mg, 1,500 mg, or 2,000 mg administered three times a day). In the trial, OLC was well tolerated and reduced phosphate absorption, as demonstrated by dose-dependent decreases in urinary phosphorus excretion from baseline during treatment.
“We are pleased with the safety findings across escalating doses of OLC and the publication in the peer-reviewed journal Clinical and Translational Science,” said Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “These positive data are a key component of our OLC New Drug Application (NDA), which is currently under review by the FDA with a Prescription Drug User Fee Action (PDUFA) date of June 28, 2025.”
The objective of the OLC dose-escalation study was to demonstrate the safety of escalating doses of orally administered OLC in healthy participants. A total of 32 participants were treated with OLC swallowable tablets or placebo tablets dosed three times per day (TID) and randomized 3:1 per arm across four OLC treatment arms of 500 mg, 1000 mg, 1500 mg and 2000 mg administered with meals over four days. The primary endpoint was safety, and the secondary endpoints measured phosphate binding capacity using the surrogate markers of phosphorus excreted in urine and feces and pharmacokinetics of OLC. The drug was well tolerated during the treatment period. Overall, there were no serious adverse events (SAE), severe or life-threatening AEs (Grade 3-4), deaths, or AEs leading to discontinuation. Most treatment-emergent adverse events (TEAE) were mild in severity. Across all treatment arms, urinary phosphorus excretion decreased from baseline in a dose-dependent manner during treatment with OLC and fecal phosphorus excretion increased from baseline.

“Demonstrating bioequivalence was a key component of our OLC New Drug Application, and we are pleased that these positive data have been published in the peer-reviewed journal, Clinical Therapeutics,” said, Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “With our NDA now under review, we are preparing for commercial launch of OLC in 2025.”
Phosphate binders are integral to hyperphosphatemia management in patients with end-stage kidney disease. This objective of the Unicycive study was to demonstrate the pharmacodynamic equivalence of orally administered OLC to LC in healthy participants. A total of 80 participants were randomized and 75 received all doses. Participants were treated with OLC swallowable 1000 mg tablets three times/day and LC chewable 1000 mg tablets three times/day in a two-way crossover design. The primary pharmacodynamic variable was the least squares mean (LSM) change in urinary phosphate excretion from baseline to the evaluation period (Days 1–4 of treatment). The LSM change in urinary phosphate excretion from Baseline to the Evaluation (Treatment) Period was similar for both OLC (–320.4 mg/day [90% CI: –349.7, –291.0]) and LC (–324.0 mg/day [90% CI: –353.3, –294.7]); the between-group LSM difference was 3.6 [90% CI: –37.8, 45.1] mg/day. Both drugs were well tolerated with an equal incidence of adverse events.
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.
