Islet Cell Adenoma

Potential to more than double the addressable patient population living with hypoglycemia resulting from insulin receptor over-activation (tumor hyperinsulinism)REDWOOD CITY, Calif., March 06, 2024 (GLOBE NEWSWIRE) -- 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 results from a preclinical pharmacology study that validate the potential for its lead clinical compound, RZ358, to treat individuals with non-islet cell tumors (NICTs) that have uncontrolled hypoglycemia. Tumor hyperinsulinism (HI) may be caused by a variety of different tumor types, resulting in islet cell tumor hypoglycemia (ICTH) and NICTH. The Company previously reported on the successful use of RZ358 under its Expanded Access Program (EAP) to treat patients with insulin-producing pancreatic islet cell tumors (ICTs), or insulinomas, causing severe and uncontrolled hypoglycemia. The therapeutic potential of RZ358 in this setting was anticipated given that ICTH is mediated by insulin and that RZ358 is known to work at the insulin receptor to decrease excess insulin binding and activity. However, it was unknown if RZ358 would have utility in NICTH where hyperinsulinism is mediated by hormones such as insulin-like growth factor-2 (IGF-2) or its variants, which likewise cause hypoglycemia by binding to and activating the insulin receptor. To test this, the Company recently completed in vitro pharmacology studies to evaluate the impact of clinically relevant concentrations of RZ358 on insulin receptor activation by IGF-2, compared to insulin. This was tested at the relative concentrations of each ligand that activate the insulin receptor and are physiologically relevant in tumor HI caused by ICTH and NICTH, respectively. These experiments successfully demonstrated the ability of RZ358 to similarly blunt both IGF-2 and insulin-mediated insulin-receptor signaling, at levels of these ligands that are disease-relevant in humans. “These data demonstrate proof of the ligand-agnostic mechanism of action of RZ358 and therefore validate its broad utility in treating hypoglycemia resulting from any form of hyperinsulinism, including expanded tumor indications,” said Dr. Brian Roberts, Chief Medical Officer of Rezolute. “Coupled with known outcomes from our clinical trials in congenital HI and the positive outcomes seen with ICTH in our expanded access program, we are excited by the potential for RZ358 to provide dramatic therapeutic benefit to cancer patients who often have limited treatment options for managing serious and uncontrolled hypoglycemia, which can accompany their cancer and disrupt treatment plans.” The Company recently reported on its successful interaction with the U.S. Food and Drug Administration (FDA) in January 2024 regarding the potential to initiate a single registrational study in patients with hypoglycemia due to tumor HI. The Company will continue to evaluate the feasibility of a development program in this indication, with the possibility of including both ICTH and NICTH patients. The inclusion of NICTH patients in a potential addressable market for RZ358 in tumor HI would more than double the population. The Company is also currently evaluating RZ358 in a Phase 3 clinical trial in congenital HI, which is a rare pediatric condition where, similar to ICTH, children overproduce insulin creating a dangerous hypoglycemic state. About Tumor Hyperinsulinism (HI)Tumor HI may be the result of two distinct types of tumors: islet cell tumors (ICTs) and non-islet cell tumors (NICTs), both of which lead to hypoglycemia due to excessive activation of the insulin receptor. Insulinomas are the most common type of functional ICT and cause hypoglycemia because of over production of insulin. NICTs can cause hypoglycemia by producing and secreting insulin-like paraneoplastic substances such as IGF-2 or related variants that bind to and activate the insulin receptor. This form of hypoglycemia can occur in more than 15 different tumor types, 60 percent of which are malignant, including hepatocellular carcinoma. The total addressable market for the combined indications causing tumor HI is estimated to be approximately 4,500 patients in the U.S. alone, including approximately 1,500 with ICTH and 3,000 with NICTH. The unique mechanism of action of RZ358 to attenuate excess insulin receptor activation mediated by insulin and related substances makes the therapy a potential universal treatment for hypoglycemia resulting from any form of hyperinsulinism. About RZ358RZ358 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 in the liver, fat, and muscle. The antibody counteracts excess insulin receptor activation by insulin and other effector substances (such as IGF-2), thereby improving hypoglycemia. Because RZ358 acts downstream from the pancreas at the insulin receptor, 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). RZ358 received Orphan Drug Designation in the United States and European Union for the treatment of congenital HI, as well as Orphan Drug Designation and Pediatric Rare Disease Designation in the U.S. In the Phase 2 RIZE study, participants with congenital HI ages two and older nearly universally achieved significant improvements 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 the Phase 3 study, RZ358 was generally safe and well-tolerated, and resulted in median improvements in hypoglycemia exceeding 80%. 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 Drug Designation status in the European Union for the treatment of Insulinoma, the primary cause of ICTH. About Rezolute, Inc.

Phase 3 clinical study of RZ358 underway in patients with congenital hyperinsulinism (cHI); topline results expected in mid-2025 Benefit shown in individual patient cases with RZ358 for tumor-associated hyperinsulinism (taHI) under Expanded Access Program (EAP); drives alignment with FDA on unmet need and potential to move into late-stage clinical development to further evaluate RZ358 in this population REDWOOD CITY, Calif., Feb. 13, 2024 (GLOBE NEWSWIRE) -- 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 its financial results for the second quarter of fiscal 2024 ended December 31, 2023, and provided an update on recent business developments and outlook. “2024 is an exciting year of execution and milestones across our pipeline, with RZ358 continuing to demonstrate benefit to patients with hypoglycemia resulting from varying causes of hyperinsulinism, and in different indications,” said Nevan Charles Elam, Chief Executive Officer and Founder of Rezolute. “We recently initiated sunRIZE, a global, pivotal, Phase 3 clinical study in patients with congenital hyperinsulinism, and we also continue to see favorable outcomes from our Expanded Access Program with RZ358, in patients with tumor-associated hyperinsulinism caused by insulinomas, for which we are evaluating a potential development program. Additionally, we completed enrollment in the Phase 2 study of RZ402 in patients with diabetic macular edema and look forward to reporting topline data from that program in the second quarter of 2024.” Clinical and Regulatory Highlights RZ358 is a monoclonal antibody for the treatment of hyperinsulinism. cHI Rezolute initiated sunRIZE, a global, pivotal, Phase 3 clinical study in participants with cHI, in Europe and other geographies outside of the U.S. Topline results expected mid-2025. Innovation and Licensing Application Passport (ILAP) designation awarded to RZ358 for the treatment of cHI by the U.K. Medicines and Healthcare products Regulatory Agency (MHRA). Designation was granted based on the recognition of substantial unmet medical need in this condition and the potential benefit to patients as evidenced by the Phase 2b RIZE study results in cHI, which safely demonstrated significant improvements in hypoglycemia. Supplements analogous PRIME designation status already granted by the European Medicines Agency (EMA) in E.U. taHI RZ358 has been shown to counteract excessive insulin action downstream, at the insulin-receptor on target organs. The unique mechanism of action of RZ358 makes the therapy a potential universal treatment for hypoglycemia resulting from any cause of hyperinsulinism, including neuroendocrine tumors (insulinomas). Given the unmet need in taHI and the potential therapeutic benefit of RZ358 as demonstrated in the individual case reports from the EAP, the Company met with FDA in January 2024 (January Meeting) and received a favorable opinion from the Agency on the feasibility of RZ358 being studied in a late-stage clinical trial as a new development program and second rare disease indication for RZ358. In the January Meeting, FDA indicated that current dose caps on cHI studies would not be applicable to taHI studies. Therefore, considering the indication is primarily adult, current partial clinical holds pertaining to cHI studies would be largely irrelevant in taHI. The Company remains engaged with FDA in the attempt to resolve ongoing partial clinical holds on clinical studies in the cHI indication. RZ402 is a selective and potent oral plasma kallikrein inhibitor for the treatment of diabetic macular edema (DME). Completed enrollment in Phase 2 U.S., multi-center, randomized, double-masked, placebo-controlled, parallel-arm study evaluating the safety, efficacy, and pharmacokinetics of RZ402 administered as an oral monotherapy over a 12-week treatment period in participants with DME who are naïve to or have received limited anti-VEGF injections. Topline results expected in the second quarter of 2024. Corporate Highlights Expanded leadership team with appointment of Daron Evans, M.S., M.B.A, as Chief Financial Officer. Mr. Evans has substantial experience leading public and private life science companies, with expertise in corporate finance, capital markets, and strategic transactions. He will help shepherd Rezolute through its next chapter in late-stage development. Second Quarter Fiscal 2024 Financial Results Cash, cash equivalents and investments in marketable debt securities totaled $96.0 million as of December 31, 2023, compared to $118.4 million as of June 30, 2023 Research and development expenses were $12.0 million for the second quarter of fiscal 2024, compared to $10.9 million for the same period in fiscal 2023, with the increase primarily attributable to increased expenditures in clinical trial activities and manufacturing costs General and administrative expenses were $3.2 million for the second quarter of fiscal 2024, compared to $3.4 million for the same period in fiscal 2023, with the decrease primarily attributable to lower personnel-related expenses Net loss was $13.9 million for the second quarter of fiscal 2024, compared to $13.6 million for the same period in fiscal 2023 About Rezolute, Inc.

Pancreatic cancer has the highest mortality rate of all major cancers with only a 3% relative-survival-rate at 5-years for the advanced form. [1], [2] Pancreatic tumors are highly resistant to chemotherapy and radiation and there are limited treatment options[2] FDA ODD designation bolsters NeoImmuneTech's determination to accelerate the clinical development of NT-I7 as a potential new therapy for this difficult-to-treat cancer ROCKVILLE, Md. , Jan. 30, 2024 /PRNewswire/ -- NeoImmuneTech, Inc. (NIT), a T cell-focused therapeutics company, today announced that the U.S. Food and Drug Administration (FDA) has granted NT-I7 (efineptakin alfa) (rhIL-7-hyFc) Orphan Drug Designation (ODD) for the treatment of pancreatic cancer.[3] Pancreatic cancer is an aggressive tumor-type associated with extremely poor prognosis. It is the third deadliest cancer in the US and European Union with a combined annual mortality of 139,000.[1],[4] Advanced pancreatic cancer has a five-year relative-survival-rate of 3%. Pancreatic cancer has been labeled as a "silent killer" because it is normally asymptomatic in the early stages which implies that it is often diagnosed at a late stage when tumors are highly resistant to treatment modalities. This underscores the critical need for new and more effective therapeutic approaches.2 Dr. Luke Oh, Ph.D., President of NeoImmuneTech, Inc. said: "We are excited that the FDA granted NT-I7 an ODD in the treatment of pancreatic cancer. This decision adds further credibility to our existing evidence that NT-I7 has the potential to bring a much-needed therapy option to people suffering from pancreatic cancer. We look forward to continuing our collaboration with FDA, as we explore the therapeutic benefits of combining NT-I7 with other anti-cancer treatments such as immunotherapies for patients with pancreatic cancer." NT-I7 has been studied in several robust phase I and II clinical trials and has demonstrated the potential to amplify T cells across the subsets, boost the immune system, and enhance the anti-tumor response in people with pancreatic cancer and other solid tumors.[5] The FDA grants ODD status to medicines intended for the treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the US. Receiving ODD may help to expedite and reduce the cost of development, approval, and commercialization of a therapeutic agent. About Pancreatic Cancer Pancreatic cancer is a malignant, aggressive tumor of the pancreas. More than 90% of cases develop in the exocrine tissue of the pancreas, which makes enzymes to digest food. The less common endocrine tumors, commonly referred to as pancreatic neuroendocrine tumors (NETs), develop in hormone-producing cells.[1} Whilst pancreatic cancer's low prevalence rate qualifies it as a rare cancer, the aggressiveness of the disease and its high death rate means that patients diagnosed have a very poor prognosis. Every year, 157,107 new patients are diagnosed with pancreatic cancer in the US and Europe Union combined. [1],[4] About NT-I7 (efineptakin alfa) (rhIL-7-hyFc) NT-I7 (efineptakin alfa) is the only clinical-stage long-acting human IL-7, and is being developed in oncologic and immunologic indications, where T cell amplification and increased functionality may provide clinical benefit. IL-7 is a fundamental cytokine for naïve and memory T cell development and for sustaining immune response to chronic antigens (as in cancer) or foreign antigens (as in infectious diseases). NT-I7 exhibits favorable PK/PD and safety pro making it an ideal combination partner. NT-I7 is being studied in multiple clinical trials in solid tumors and as vaccine adjuvant. Studies are being planned for testing in hematologic malignancies, additional solid tumors and other immunology-focused indications. About NeoImmuneTech, Inc. NeoImmuneTech, Inc. (NIT) is a clinical-stage T cell-focused biopharmaceutical company, dedicated to expanding the horizon of immuno-oncology and enhancing immunity to infectious diseases. NIT is led by the scientific founder and inventor of NT-I7 (efineptakin alfa) and has a strong executive team with rich industry experience. NIT is expanding rapidly in personnel and operations, as well as partnering with industry and academic leaders to investigate NT-I7 as monotherapy and in combination with various immunotherapeutics.
