Cash runway into 2027, which is expected to support application resubmission, potential FDA approval, and launch of OLC
LOS ALTOS, Calif., Oct. 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 an update from its meeting with the U.S. Food and Drug Administration (FDA) and timing of the resubmission of its New Drug Application (NDA) for Oxylanthanum Carbonate (OLC) following receipt of a Complete Response Letter (CRL) on June 30, 2025. The Type A FDA meeting was held to discuss the resolution of the single deficiency identified in the CRL related to the compliance status of a third-party manufacturing vendor. No other concerns have been identified to the Company, including pre-clinical, clinical, or safety data submitted as part of the NDA. Following receipt of the official meeting minutes from the Type A meeting and engaging in discussions with its third-party manufacturing vendor, the Company plans to resubmit the NDA for OLC by year-end.
“We are grateful for the highly constructive feedback and detailed meeting minutes we received from the FDA and look forward to resubmitting the NDA as we advance OLC toward potential approval,” said Shalabh Gupta, MD, Chief Executive Officer of Unicycive. “Following our interactions with the FDA, we are very encouraged about the potential for a swift resolution of the issue raised in our CRL and we believe we are now on track to resubmit our NDA before the end of the year, which could lead to a PDUFA date in the first half of 2026. With over $42 million on our balance sheet as of September 30, we have a cash runway into 2027, enabling us to work through the regulatory approval process and continue to advance preparations for potential OLC commercialization while focusing on our mission to deliver improved treatment options for patients with hyperphosphatemia on dialysis.”
About Oxylanthanum Carbonate (OLC)
OLC is an investigational oral phosphate binder that leverages proprietary nanoparticle technology to deliver high phosphate binding potency, reducing the number and size of pills that patients must take to treat hyperphosphatemia in patients with chronic kidney disease (CKD) on dialysis. Its potential best-in-class profile may have meaningful patient adherence benefits over currently available treatment options as it requires a lower pill burden. 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). Annually there are over 450,000 individuals in the U.S. that require medication to control their phosphate levels.1 Uncontrolled hyperphosphatemia is strongly associated with increased death and hospitalization for CKD patients on dialysis. 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.
