Study Summary

This trial is testing a new drug to treat Parkinson's disease in patients with a pathogenic GBA1 mutation. The study will last 5 years and will evaluate the safety, tolerability, immunogenicity, biomarkers, and clinical efficacy measures of the drug.

Who is the study for?
This trial is for adults with Parkinson's Disease who have a specific GBA1 mutation, weigh between 88-242 lbs with a BMI of 18-34, and are in moderate to severe stages (Hoehn and Yahr Stage III-IV). They must be on stable medications for Parkinson's or Gaucher Disease treatments if applicable. Participants need a reliable informant, updated vaccinations, and agree to use effective contraception if necessary. Exclusions include other significant CNS diseases, certain MRI findings, hypersensitivity to study drugs, uncontrolled health conditions like hypertension or diabetes.Check my eligibility
What is being tested?
The PROPEL trial tests the safety of PR001 (LY3884961), an investigational drug administered into the spinal fluid for those with Parkinson's linked to GBA1 mutations. It includes two dosage levels over five years—initially focusing on safety and efficacy within the first year followed by long-term effects monitoring.See study design
What are the potential side effects?
Potential side effects may include reactions related to LY3884961 administration such as inflammation at injection site or immune response issues due to its novel nature; sirolimus could cause mouth sores or increase infection risk; methylprednisolone might lead to weight gain, mood swings or increased blood sugar.
