U.S. Food and Drug Administration (FDA) grants Breakthrough Therapy Designation to ersodetug for hypoglycemia due to tumor hyperinsulinism

REDWOOD CITY, Calif., May 13, 2025 (GLOBE NEWSWIRE) -- Rezolute, Inc. (Nasdaq: RZLT) (“Rezolute” or the “Company”), a late-stage rare disease company focused on treating hypoglycemia caused by hyperinsulinism (HI), today reported financial results and provided a business update for the three months ended March 31, 2025.

“The Phase 3 sunRIZE study in congenital HI is on track to complete enrollment this month and we are poised to start our registrational upLIFT study for tumor HI mid-year,” said Nevan Charles Elam, Chief Executive Officer and Founder of Rezolute. “Each of our programs received Breakthrough Therapy Designation from FDA this year. We look forward to continued discussions with the agency with a focus on treating hypoglycemia caused by all forms of hyperinsulinism with the goal of advancing our novel therapy towards approval and commercialization.”

Recent Pipeline Progress and Anticipated Milestones

Congenital HI

sunRIZE, a Phase 3, multicenter, double-blind, randomized, controlled safety and efficacy registrational study, is ongoing and enrollment is expected to conclude in May 2025.
- U.S. sites are activated and enrolling patients.
- Topline results expected in December 2025.
Upon completion of an interim analysis in April 2025, an independent Data Monitoring Committee recommended continuation of the sunRIZE study as planned without an increase to the study sample size.
- The analysis was intended to evaluate the study for futility or otherwise to inform a potential sample size increase, for purposes of optimizing the study power and statistical confidence in the final analysis outcomes.
- The Company remains blinded to the results.

Tumor HI

In May 2025, FDA granted Breakthrough Therapy Designation (BTD) to ersodetug for the treatment of hypoglycemia due to tumor HI.
- BTD was granted based on clinical trial data across the overall HI program and a recognition of the mechanistic applicability to tumor HI, further validated by real-world experience in tumor HI patients who have been successfully treated with ersodetug throughout the U.S. in the Company's Expanded Access Program.
A registrational study for ersodetug in patients with tumor HI, the “upLIFT” study, is anticipated to begin in the middle of 2025 with topline data expected in the second half of 2026.
- Utilizing BTD, the Company plans to engage further with FDA to discuss the registrational trial, including the necessary data package to support a BLA filing and potential approval for the tumor HI indication.

Corporate Updates

In March 2025, the Company announced the appointment of rare disease commercial leader, Erik Harris, to its Board of Directors.
- Mr. Harris is an experienced board member and commercial executive with a proven track record in the industry, currently serving as Chief Commercial Officer at Ultragenyx.
- His insights will be invaluable as the Company advances through clinical development and prepares for potential commercialization.
In April 2025, the Company announced the closing of an underwritten offering raising approximately $97 million.
- Cash runway extended to middle of 2027.
- The net proceeds will be used for research and development, general corporate expenses and working capital needs.

Fiscal Third Quarter Financial Results

Cash, cash equivalents and investments in marketable securities were $88.4 million as of March 31, 2025, compared to $127.1 million as of June 30, 2024.

Research and development expenses were $15.3 million for the third quarter of fiscal 2025, compared with $12.4 million for the same period a year ago, with the increase primarily attributable to increased expenditures in clinical trial activities, manufacturing costs and higher personnel-related expenses, which include employee compensation.

General and administrative expenses were $4.7 million for the third quarter of fiscal 2025, compared with $3.8 million for the same period a year ago, with the increase primarily attributable to professional fees and employee-related expenses as a result of increased headcount.

Net loss was $18.9 million for the third quarter of fiscal 2025 compared with a net loss of $17.1 million for the same period a year ago.

About Ersodetug

Ersodetug is a fully human monoclonal antibody that binds allosterically to the insulin receptor to decrease receptor over-activation by insulin and related substances (such as IGF-2) in the setting of hyperinsulinism (HI), thereby improving hypoglycemia. Because ersodetug acts downstream from the pancreas, it has the potential to be universally effective at treating hypoglycemia due to any congenital or acquired form of HI.
