Exhibit 99.1

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

– FDA sets PDUFA Action Date of June 28, 2025

– Company Preparing for 2025 Commercial Launch –

LOS ALTOS, California, November 11, 2024 -- 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 U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for Oxylanthanum Carbonate (OLC) and has set a Prescription Drug User Fee Act (PDUFA) target action date of June 28, 2025. If approved, OLC has the potential to meaningfully improve the treatment burden for hyperphosphatemia patients with chronic kidney disease (CKD) on dialysis.

“We are thrilled with the FDA acceptance of our first NDA, a significant milestone towards our efforts to bring this important treatment option to patients with kidney disease if approved,” said Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “CKD patients on dialysis with hyperphosphatemia are often saddled with an onerous treatment regimen that includes having to take as many as 12 pills per day. OLC may have meaningful patient adherence benefits over currently available treatment options as it requires a lower pill burden for patients in terms of the number and size of pills per dose, and the pills are swallowed instead of chewed for added convenience. With our NDA now under review, we are preparing to commercialize and launch OLC in the second half of 2025, if approved.”

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

As previously announced, the FDA granted a waiver for the NDA application PDUFA fees, representing a significant savings of approximately $4 million for Unicycive.

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 thirty 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.
