PASADENA Trial Summary

This trial will evaluate whether the drug prasinezumab is effective in treating early Parkinson's Disease, compared to a placebo. The study will last for a total of 52 weeks, and participants will be monitored for long-term safety and efficacy.

Who is the study for?
This trial is for adults with early Parkinson's Disease (PD) who have been diagnosed within the last 2 years and are at Hoehn and Yahr Stage I or II. They should not need PD medication for at least a year, may be on stable MAO-B inhibitors, must have a BMI of 18-34 kg/m^2, weigh between 45-110 kg, and if of childbearing potential, use effective contraception.Check my eligibility
What is being tested?
The study tests Prasinezumab (RO7046015/PRX002), an intravenous drug against a placebo in untreated or minimally treated early PD patients over one year. It includes a blinded extension where all participants receive treatment and an open-label phase to assess long-term effects.See study design
What are the potential side effects?
Potential side effects aren't specified here but could include typical reactions to monoclonal antibodies such as infusion-related reactions, allergies to components like citrate or polysorbate 20, fatigue, headache, joint pain or digestive issues.
