Share

Unicycive says that after discussions with FDA and the company’s third-party manufacturing vendor, it plans to resubmit its NDA for oxylanthanum carbonate (OLC) to FDA before the end of 2025. FDA had issued a 6/30 complete response letter (CRL) citing concerns about the compliance status of Unicycive’s third-party manufacturing vendor and no other issues.

“We are grateful for the highly constructive feedback and detailed meeting minutes we received from FDA and look forward to resubmitting the NDA as we advance OLC toward potential approval,” Unicycive CEO Shalabh Gupta said in a statement. “Following our interactions with 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.”

OLC is described as 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 on dialysis. The company says it is seeking 505(b)(2) approval based on data from three clinical studies.
