Exhibit 99.1

Phase 2 RIZE Study Sub-Analyses to be Presented at the 2024 Pediatric Endocrine Society Annual Meeting

REDWOOD CITY, Calif., April 23, 2024 – Rezolute, Inc. (Nasdaq: RZLT) (“Rezolute” or the “Company”), a clinical-stage biopharmaceutical company committed to developing novel, transformative therapies for serious metabolic and rare diseases, today announced that a poster titled “An Analysis of Overnight Hypoglycemia in Patients with Congenital Hyperinsulinism: Results from the RZ358-606 (RIZE) Study” will be presented at the Pediatric Endocrine Society (PES) Annual Meeting, to be held May 2-5, 2024 at the Sheraton Grand Chicago Riverwalk.

Paul Thornton, M.D., a Pediatric Endocrinologist with expertise in congenital HI, will present the poster, which details findings from the Company’s Phase 2 RIZE study evaluating the treatment of congenital hyperinsulinism (HI) with RZ358 in pediatric patients. While primary and key secondary glycemic endpoints (weekly events and daily percent time) from the RZ358-606 (RIZE) study have been previously reported, the current sub-analyses highlight the benefits of RZ358 during the vulnerable overnight fasting period, utilizing continuous glucose monitor (CGM) to evaluate average time in hypoglycemia (<70 mg/kg) and average glucose levels overnight. These and previously reported results, including improvements in overall hypoglycemia events and time of up to ~90% at the top doses, suggest that RZ358 has the potential to be a safe and effective therapy to treat all forms of congenital HI. A Phase 3 study is currently underway.

About Congenital Hyperinsulinism

Congenital hyperinsulinism (HI) is the most common cause of recurrent and persistent hypoglycemia in children. Patients with congenital HI typically present with signs or symptoms of hypoglycemia within the first month of life. These episodes can result in significant brain injury and death if not recognized and managed appropriately. Additionally, recurrent, or cumulative, hypoglycemia can lead to progressive and irreversible damage over time, including serious and devastating brain injury, seizures, neuro-developmental problems, feeding difficulties, and significant impact on patient and family quality of life. In cases of congenital HI that are unresponsive to medical management, surgical removal of the pancreas may be required. In those with diffuse congenital HI where the whole pancreas is affected, a near-total pancreatectomy can be undertaken, although about half of these children will continue to have hypoglycemia and require medical treatment for congenital HI.

About RZ358

RZ358 is a fully human monoclonal antibody that works downstream from the pancreas and other sources of insulin or related paraneoplastic substances, and instead binds to a unique allosteric site on insulin receptors at target tissues such as liver, fat and muscle. The antibody counteracts excess insulin receptor activation by insulin and related effector substances (such as IGF-2), thereby improving hypoglycemia. Because RZ358 acts downstream from the pancreas, it has the potential to be universally effective at treating hypoglycemia due to congenital HI, regardless of the causative genetic defect, as well as acquired forms of HI such as those mediated by insulinomas (ICTs) and other tumor types (NICTs).

In the Phase 2 RIZE study in patients with congenital HI ages two and older, nearly all participants achieved significant improvement in hypoglycemia across multiple endpoints, including the primary and key secondary endpoints planned for the sunRIZE study. At doses and exposures that are planned for sunRIZE, RZ358 was generally safe and well-tolerated, and resulted in median improvements in hypoglycemia of up to ~90%. Based on the RIZE clinical trial outcomes and the evidence of benefit in this serious condition with substantial unmet medical need, RZ358 was subsequently granted a priority medicines (PRIME) designation by the European Medicines Agency (EMA) and an Innovation Passport designation by the U.K. Innovative Licensing and Access Pathway (ILAP) Steering Group for the treatment of congenital HI. RZ358 also received orphan drugand pediatric rare disease designation in the U.S., and orphan drug designation in the European Union for the treatment of Insulinoma, the primary cause of ICTH.
