Unicycive Announces Full Year 2022 Financial Results and Provides Business Update

Closed transformational fundraise that included $30 million financing upfront with up to an additional $100 million tied to satisfaction of milestones

Financing by new and existing institutional investors from high-profile healthcare-focused funds to support launch and commercialization of investigational new drug, Renazorb™

Company on track to file New Drug Application with the U.S. Food and Drug Administration in mid-2023 with potential for approval and launch in 2024

LOS ALTOS, Calif., March 31, 2023 -- Unicycive Therapeutics, Inc. (Nasdaq: UNCY) (the “Company” or “Unicycive”), a clinical-stage biotechnology company developing therapies for patients with kidney disease, today announced its financial results for the full year ended December 31, 2022 and provided a business update.

“Our recent financing, combined with the successful, pivotal bioequivalence (BE) study for Renazorb™, is transformational for Unicycive as they support Renazorb’s best-in-class potential as a treatment for hyperphosphatemia and provide funding for its commercial launch, if approved,” said Shalabh Gupta, M.D., Chief Executive Officer of Unicycive. “Importantly, we are on track to file a New Drug Application (NDA) for Renazorb marketing approval with the U.S. Food and Drug Administration (FDA) in mid-year, which should provide additional funding in connection with our recent financing agreement upon approval.”

“We continue to make progress with our plans for the commercialization of Renazorb for the treatment of hyperphosphatemia, where our strengthened balance sheet provides the resources needed to drive increased market awareness of Renazorb’s potential best-in-class product profile and to plan and execute our go-to-market strategy to bring this novel treatment to patients. If approved, Renazorb may dramatically reduce the pill burden that patients endure with currently available medications.

“The global market opportunity for treating hyperphosphatemia is projected to be in excess of $2.5 billion in 2023, with the United States accounting for more than $1 billion of that total. 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. The timing of Renazorb’s expected launch coincides favorably with the pending expansion of Medicare patient access to phosphate binders in 2025 when these products are added to the end stage renal disease (ESRD) PPS through the Center for Medicare and Medicaid’s Transitional Drug Add-On Payment Adjustment (“TDAPA”) program,” added Dr. Gupta.

Key Highlights of the Fourth Quarter 2022 and Recent Months

Clinical Programs

Renazorb (lanthanum dioxycarbonate)

Renazorb 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). Renazorb 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 smaller and fewer number of pills per dose and is swallowed instead of chewed.

Unicycive is looking forward to presenting data at the upcoming International Society of Nephrology’s World Congress of Nephrology 2023 meeting (WCN) taking place from March 30-April 2. The data to be presented include data highlighting Renazorb’s phosphate binding ability from a Phase 1 clinical study, preclinical animal data evaluating Renazorb’s ability to reduce urine phosphate levels and a study that evaluated the daily medication volume of various phosphate binders to determine the option with the lowest required daily volume.

Unicycive will also present data from a study that evaluated the medication weight of various phosphate binders required to bind 1 gram of phosphorus at the National Kidney Foundation Spring Meeting (April 11-15, 2023) and highlighted Renazorb’s potential best of class properties.

The totality of these data provide further evidence of the benefits of Renazorb as a powerful phosphate binder and highlight its enhanced product profile, which has the potential to improve medication compliance and, thereby, improve outcomes and quality-of-life for patients with hyperphosphatemia.

The hyperphosphatemia treatment market exceeds one billion dollars in the U.S. and is more than double that in the rest of the world. The Unicycive team is preparing to capitalize on this substantial opportunity by offering patients and providers an attractive treatment alternative. In tandem with the clinical development program, the Company is focused on its commercialization plans for Renazorb in the U.S. and around the world. Unicycive is conducting important market research to inform its brand and market access strategy and comprehensive launch plan for Renazorb.

UNI-494

UNI-494 is a patent-protected new chemical entity for the treatment of acute kidney injury (AKI). UNI-494 is a novel proprietary drug that selectively binds to the SUR2B subunit of the mitochondrial K_ATP channel and activates it to restore mitochondrial function and reduce oxidative stress. UNI-494 is cleaved by esterase enzymes to form nicorandil, the active metabolite.

Unicycive expects to dose the first patient in its first-in-humans Phase 1 study of UNI-494 in healthy volunteers in the United Kingdom and plans to file a corresponding Investigational New Drug (IND) application with the FDA in 2024 for a Phase 2 proof-of-concept trial in AKI patients.

The Company is looking forward to presenting a bolus of data in support of the potential for UNI-494 as a treatment for AKI at the WCN where preclinical data from a dog study that analyzed systemic exposure to UNI-494 and nicorandil will be highlighted in a poster.

Data supporting UNI-494’s potential to treat acute and chronic kidney disease will be presented at the 28th International Conference on Critical Care in Nephrology: the Acute Kidney Injury & CRRT 2023 Conference (March 30-April 1).

In addition, the Company will present data at the upcoming National Kidney Foundation Spring Meeting (April 11-15, 2023), where results from three pre-clinical studies of UNI-494 underscore its potential to be reno-protective and to have low risk of drug-drug interactions, both of which are important findings for this product candidate as a promising therapeutic for AKI, a condition for which there are currently no FDA approved therapies.

Financial Results for the Year Ended December 31, 2022

Research and development expenses for the full year ended December 31, 2022 were $12.4 million, compared to $6.1 million for the same period in 2021. This increase was primarily attributable to development costs of $6.5 million for product formulation, clinical study, and preclinical study services in the current period.

General and administrative expenses for the year ended December 31, 2022 were $6.6 million, compared to $2.9 million for the year ended December 31, 2021. This increase was primarily attributable to an increase of $1.4 million in consulting and professional services costs. Labor costs increased $0.7 million due to hiring of new employees. Non-cash stock compensation costs increased $0.4 million. Insurance expense for directors and officers increased $0.5 million, and rent, travel, supplies and other costs increased $0.6 million.

Net loss for the 12-month period ended December 31, 2022 was $18.1 million, or $1.20 per share of common stock, compared to a net loss of $10.0 million, or $0.86 per share of common stock, for the same 12-month period in 2021. This increase was primarily attributable to increased development costs.

As of December 31, 2022, cash and cash equivalents totaled $0.5 million compared with $16.6 million in cash and cash equivalents held at December 31, 2021. Following the close of the fourth quarter ended December 31, 2022, the Company completed a securities purchase agreement with certain healthcare-focused institutional investors that will provide up to $130.0 million in gross proceeds through a private placement and that included initial upfront funding of $30.0 million.
