Patient Resources

Understanding the TEV-56286 Study

We want you to feel completely comfortable and informed. Here are clear answers to common questions regarding this Multiple System Atrophy (MSA) extension trial.

What is a clinical trial and is it safe?

Clinical trials are carefully designed research studies that evaluate the safety and effectiveness of medical treatments. Participant safety is our absolute highest priority. This trial is rigorously monitored by medical professionals, ethical review boards, and health authorities to ensure strict, ongoing safety protocols are maintained.

How long will I be in the study?

The planned total duration for this specific extension trial is approximately 100 weeks. During this period, you will have regular visits and health assessments with the study team to closely monitor your well-being and progress.

What are the possible risks and side effects?

As with any clinical research, there may be risks involved. The primary objective of this trial is to thoroughly describe the long-term safety and tolerability of TEV-56286. Before you agree to participate, the study doctor will provide a detailed explanation of all known potential risks, side effects, and expected benefits.

Will my information be kept confidential?

Yes, absolutely. We maintain strict confidentiality protocols. All of your personal and medical information collected during the study is securely stored and protected in full compliance with national healthcare privacy regulations. Your identity will never be disclosed in any study reports.

Can I leave the study if I change my mind?

Yes. Your participation is completely voluntary. You have the fundamental right to withdraw from the study at any time, for any reason, without needing to explain why. Leaving the study will not result in any penalty or affect the quality of your standard medical care.

Will I receive the actual medication or a placebo?

Because this is an extension trial specifically for participants who have completed the initial double-blind study (TV56286-NDG-20039), the study doctor will explain exactly how the investigational medication is administered during this new phase. Please discuss your specific treatment plan directly with the study team.

What happens after the study ends?

After the approximately 100-week period concludes, the study team will conduct final, comprehensive health assessments. Your study doctor will then discuss the results with you and help determine the best next steps for your ongoing care and management of Multiple System Atrophy.
