Fiscal First Quarter Financial Results

Cash, cash equivalents and investments in marketable securities were $117.8 million as of September 30, 2024, compared to $127.1 million as of June 30, 2024.

Research and development expenses were $12.8 million for the first quarter of fiscal 2025, compared with $12.2 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 $4.2 million for the first quarter of fiscal 2025, compared with $3.7 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 $15.4 million for the first quarter of fiscal 2025 compared with a net loss of $14.5 million for the same period a year ago.

About Ersodetug

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

About sunRIZE

The Phase 3 sunRIZE study is a multi-center, randomized, double-blind, placebo-controlled, parallel arm study designed to evaluate the efficacy and safety of ersodetug in patients with congenital HI who are experiencing poorly controlled hypoglycemia. Participants between the ages of 3 months to 45 years old are eligible to participate. The study is enrolling up to 56 participants in more than a dozen countries around the world.

About Rezolute, Inc.

Rezolute is a late-stage rare disease company focused on significantly improving outcomes for individuals with hypoglycemia caused by hyperinsulinism (HI). The Company’s antibody therapy, ersodetug, is designed to treat all forms of HI and has shown substantial benefit in clinical trials and real-world use for the treatment of congenital HI and tumor HI.
