Clinical Trials

A clinical trial is a research study conducted in humans with the goal of answering specific questions about new therapies, vaccines, diagnostic procedures, or new ways of using known treatments. Clinical trials are used to determine whether new drugs, diagnostics, or treatments are both safe and effective. Clinical trials are critically important for developing cures for conditions like FTD.

PROCLAIM Genetic Therapy Trial (Phase I/II)

​Title: 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) (sponsor: Prevail Therapeutics).

This clinical trial research study is being conducted to assess the safety, tolerability, and effects of an investigational genetic therapy product called LY3884963 on progranulin protein (PGRN) levels in blood and cerebrospinal fluid (CSF).

Description

​LY3884963 will be administered as a single dose via injection into the fluid area at the base of the skull called the cisterna magna by a trained radiologist. The procedure will be performed with the patient under general anesthesia and using imaging guidance. This will involve a 2-night inpatient stay. Patients will be given medications to reduce any risk of inflammation before and after the injection procedure. Participation in this study will last for 5 years. The first year is more involved with a higher number of visits to monitor safety and tolerability (Dosing, Day 7, Day 14, Day 21, Month 1, Month 1.5, Month 2, Month 3, Month 6, Month 9, Year 1). Years 2-5 will involve a visit every 6 months to assess the effects of long-term exposure to LY3884963 on safety and efficacy outcomes. If you agree to join the study, you will be asked to complete the following research procedures at various time points over the duration of the study.

Eligibility 
​​
Symptomatic individuals who are confirmed carriers of a GRN mutation causative of FTD.

Study Activities
​​

  • A one-time dose of LY3884963 injected into the fluid at the base of the skull by an interventional neuro-radiologist (one-time procedure) with a two-night inpatient stay

  • Magnetic Resonance Imaging (MRI) / Magnetic Resonance Angiography (MRA)

  • Lumbar Punctures (LP)

  • Electrocardiograms (ECG)

  • Vital signs (blood pressure, heart rate, etc.)

  • Urine tests for safety and drug screen

  • Viral shedding tests (urine, saliva, feces)

  • Physical and neurological examinations

  • Blood tests for safety and PGRN levels

  • Cognitive testing

  • Questionnaires about mood and everyday activities (for both patient and study partner)
