Develops clinical programs for hyperinsulinism-related hypoglycemia, centered on the intravenous antibody ersodetug. The business is pre-commercial, concentrated on congenital and tumor HI, and shaped by FDA alignment after the congenital study miss plus execution of the tumor HI trial.
Develops a pre-commercial rare-disease portfolio focused on hypoglycemia caused by hyperinsulinism. Ersodetug, an intravenously administered human monoclonal antibody, is the central asset and is being evaluated for congenital HI and tumor HI.
Operates from Redwood City with one reportable segment, no meaningful revenue generated to date, and clinical-regulatory work that reaches beyond the United States. RZ402 remains a lower-weight licensed diabetes-eye-disease asset after prior clinical data, but the public pipeline centers on ersodetug.
Depends on clinical execution, regulatory alignment, and capital access. The congenital HI path needs FDA alignment after sunRIZE missed its primary and key secondary endpoints, while the tumor HI program depends on upLIFT enrollment and topline data.
