Rezolute Announces Q1 Fiscal 2025 Financial Results and Business Update

Rezolute, Inc., a biopharmaceutical company focusing on treatments for rare diseases, has made significant strides in its development of Ersodetug, a fully human monoclonal antibody designed to treat hyperinsulinism (HI). Ersodetug is currently progressing through two Phase 3 clinical trials, aiming to address congenital HI and tumor HI. The company's CEO, Nevan Elam, emphasized the importance of advancing these trials to potentially offer a meaningful therapy for patients with limited treatment options.

The sunRIZE Phase 3 clinical trial is a global, pivotal study evaluating the efficacy and safety of Ersodetug for patients with congenital HI. This study has successfully enrolled participants outside the United States and is set to begin enrolling U.S. participants in early 2025. The trial intends to assess the impact of Ersodetug on patients experiencing poorly controlled hypoglycemia. The sunRIZE study is enrolling up to 56 participants, aged between 3 months and 45 years, across more than a dozen countries. The topline results from this study are expected by the second half of 2025.

In parallel, Rezolute is preparing for a Phase 3 study of Ersodetug for patients with tumor HI. The start-up activities for this trial are underway, with patient enrollment anticipated to begin in the first half of 2025. The topline results from this study are expected in the second half of 2026.

Financially, Rezolute reported its fiscal first-quarter results for 2025, which ended on September 30, 2024. The company had cash, cash equivalents, and investments totaling $117.8 million, down from $127.1 million at the end of June 2024. Research and development expenses for the quarter were $12.8 million, compared to $12.2 million in the same period the previous year, reflecting increased clinical trial activities, manufacturing costs, and higher personnel-related expenses. General and administrative expenses rose to $4.2 million from $3.7 million, primarily due to professional fees and increased headcount. The net loss for the first quarter was $15.4 million, compared to a net loss of $14.5 million in the same period of the previous year.

Ersodetug works by binding to a unique allosteric site on insulin receptors, counteracting the over-activation caused by insulin and related substances like IGF-2. This mechanism helps improve hypoglycemia in HI patients by acting downstream from the pancreas, potentially making it effective for various forms of HI.

Rezolute remains committed to advancing its clinical programs, with a keen focus on 2025 as a pivotal year for the company's progress. The anticipated milestones for the sunRIZE and tumor HI studies are crucial steps towards potentially providing new treatment options for HI patients.

As a late-stage biopharmaceutical company, Rezolute is dedicated to developing transformative therapies for rare diseases. The company's lead product, Ersodetug, has shown significant promise in treating both congenital and tumor-related HI, positioning Rezolute at the forefront of addressing unmet medical needs in this area.
