Phase 12 Open-Label Study Evaluating Safety and Tolerability of a Single Intravenous Dose of LY3884961 in Adults with Peripheral Gaucher Disease

What this Trial Is About

Researchers are evaluating LY3884961, a genetic therapy delivered as a single intravenous infusion, in adults with peripheral symptoms of Gaucher Disease. This Phase 12, open-label, multicenter study aims to assess the safety and tolerability of different dose levels of LY3884961. The study includes dose-finding cohorts followed by an expansion cohort to better understand the therapys effects in this patient group. Participants will receive one dose of LY3884961 and will be monitored closely for 18 months to evaluate safety, tolerability, immune response, biomarkers, and treatment effects. The study may include up to three dose levels tested in small groups of patients, with an additional group enrolled afterward. The total study duration for each patient is about five years, including a screening period of up to 60 days. During the trial, participants will have regular evaluations including laboratory tests, imaging, and clinical assessments to track treatment-emergent adverse events and changes in spleen volume, platelet count, and relevant biomarkers. Researchers will also monitor the use and discontinuation of enzyme replacement or substrate reduction therapies. Long-term safety and immune response will be followed for up to 42 months after the initial 18-month period.
