💬In plain words
What the trial is, and whether it could suit you
The present study aims to conduct a randomized controlled trial to evaluate the efficacy and safety of 3-n-Butylphthalide (NBP) in improving symptoms in patients with Multiple System Atrophy (MSA). The main questions it aims to answer are:
1. To evaluate whether NBP soft capsules, compared with placebo, alleviates the major clinical symptoms in patients with MSA.
2. Whether NBP application is safe to treat patients with MSA. In this trial, NBP will be compared with placebo (similar soft capsule without effective component of NBP) to demonstrate if NBP can alleviates MSA symptoms
Participants of ENMSA will:
1. Take NBP or Placebo three times a day for 6 months
2. Be served with clinical visit four times for follow-up and tests
3. Keep a diary of drug application and symptom changes
