A Phase 3, Randomized, Double-Blind, Placebo-Controlled, Parallel-Arm Study to Evaluate the Efficacy and Safety of RZ358 in Patients with Congenital Hyperinsulinism
The Phase 3 pivotal study is designed to evaluate the efficacy and safety of RZ358 for the treatment of congenital hyperinsulinism (HI) as add-on to standard-of-care (SOC) therapy compared to SOC alone over 24 weeks and to evaluate the longer-term safety and efficacy of RZ358 during a subsequent open-label extension (OLE) period.
• At screening, aged ≥ 3 months and ≤ 45 years old.
• An established clinical diagnosis of congenital HI (hyperinsulinism), with or without identification of a known monogenic variant by genetic testing.
• Participant has failed to achieve adequate glycemic control with appropriate and reasonable trials of locally accepted and available Standard of Care (SOC) medical therapies (e.g., diazoxide and somatostatin analogs (SSAs)) per the judgment of the investigator.
• Experiencing ≥ 3 hypoglycemia events per week by screening Self-Monitoring Blood Glucose (SMBG) and average daily percent time with hypoglycemia of ≥ 8% of the monitored screening Continuous Glucose Monitor (CGM) time.
