Phase 1/2 Clinical Trial of LY3884963 in Patients With Frontotemporal Dementia With Progranulin Mutations (FTD-GRN) (NCT04408625)

A Phase 1/2 Ascending Dose Study to Evaluate the Safety and Effects on Progranulin Levels of LY3884963 in Patients With Fronto-Temporal Dementia With Progranulin Mutations (FTD-GRN)

🔵 Active, Not Recruiting Phase1 / Phase2 💊 Investigational Drug / Biologic Sponsor: Prevail Therapeutics

🩺 Plain-English Summary (8th-Grade Level)

Study J4B-MC-OKAA is a Phase 1/2, multi-center, open-label ascending dose, first-in-human study that will evaluate the safety and effect of intra-cisternal LY3884963 administration on progranulin protein (PGRN) levels in patients with frontotemporal dementia with progranulin mutations (FTD-GRN). Two escalating dose (low dose and medium dose) cohorts are planned, as well as one bridging cohort which will allocate patients to receive either low or medium dose. The duration of the study is 5 years. During the first year, patients will be evaluated for the effect of LY3884963 on safety, tolerability, immunogenicity, biomarkers, and efficacy. Patients will follow up for an additional 4 years to monitor safety and changes on selected biomarkers and clinical outcomes.
