Participate

We are inviting you to take part in a research study!

The ENSURE Studies are studying a potential new oral drug that may help treat Relapsing Multiple Sclerosis. Over 2,000 people from around the world will join the studies and you could be one of them.

The ENSURE Studies will enroll participants at 80-120 medical sites, worldwide. Participation will include approximately 8 visits to a study center over 16 months. After you end the main treatment period, the study doctor will assess if you are eligible to continue in the extended treatment period, which will allow you to continue your treatment with the study drug for up to 8 years.

There is no cost to take part in the ENSURE Studies. In addition, participants may receive reimbursement for reasonable travel expenses and costs associated with their participation.

You may be eligible to participate in the ENSURE Studies if you:

  • Are between 18 and 55 years old
  • Are diagnosed with RMS
  • Have a recent history of active RMS, with at least 2 relapses in the last 2 years or 1 relapse in the last year

There is no cost to participate in the study. All study-related care, including the study drug will be provided. Those who take part in the study may receive reimbursement for travel expenses.

Sign Up

What happens if I sign up? We will match you to a study center in your area that needs volunteers with Multiple Sclerosis or notify you when one becomes available. The study team will then contact you and you may have the opportunity to participate if qualified.


If you think you might like to participate in the ENSURE Studies or would like more information, please enter your information below so we can see if you may qualify and can contact you about the studies. Keep in mind that participation is entirely voluntary. If you do decide to take part in a study, you may change your mind about participating at any time.

About Relapsing Multiple Sclerosis (RMS)

Multiple Sclerosis (MS) is a chronic disease affecting the brain and spinal cord. Patients with MS can experience a variety of symptoms, including problems with vision, bladder control, arm or leg movement, sensation or balance.1

Relapsing MS is characterized by attacks, also called relapses, meaning new or worsening of symptoms, lasting for at least 24 hours before full or partial recovery.2

The purpose of the ENSURE Studies is to investigate how safe and effective the study drug is in helping treat patients with Relapsing Multiple Sclerosis by reducing relapses.

Frequently Asked Questions

What is a research study?

A research study (also called a clinical trial) is a medical study that helps to answer important questions about an investigational drug – these may include how well an investigational study drug works for a certain condition. All medications must be tested in clinical research studies before they can be approved and prescribed to patients.

A research study is the process by which new and innovative medications, interventions and treatments are approved and brought to market, so people can live happier and healthier lives. Even over-the-counter medications, such as NSAIDs, you may have used to counteract a headache, have gone through the clinical research study process before it was available at your local pharmacy.

The ENSURE Studies are global studies testing the safety and efficacy of a new potential drug to help reduce relapses in those diagnosed with Relapsing Multiple Sclerosis.

The ENSURE Studies will enroll over 2,000 participants at 80-120 sites worldwide and will include 8 visits to a study center over 16 months and an extended treatment period. The extended treatment period will allow participants to receive the study drug for up to 8 years if a study doctor determines their eligibility.

Volunteers who qualify to take part in the study may receive reimbursement for reasonable travel and expenses. Please discuss this with the study team when they contact you.

There is no cost to participate in the ENSURE Studies. If you qualify, all study-related care, including the study drug, is provided at no cost.

The research team will be able to explain more about what the ENSURE Studies will involve, and it is up to you to decide if you want to take part. Participation in this study is voluntary. Whether or not you decide to participate in this study will not affect your current or future relationships with your doctors. If you decide to participate, you are free to withdraw at any time without affecting those relationships.

We match you to a study center within a close travel distance from your home. If we are not running the study in your area currently, with your permission, we will keep you in our database and reach out once a study in your area becomes available. If, at any time, you decided you no longer want your information stored, you can opt out and we will delete your details.

About the ENSURE Studies

The ENSURE Studies will enroll over 2,000 participants with Relapsing Multiple Sclerosis at approximately 80-120 study sites, worldwide.

The study will include approximately 8 visits to a study center over 16 months as well as an extended treatment period if you are eligible. The initial study period includes the screening period, which lasts up to 4 weeks and will allow a study doctor to assess participants’ eligibility for the study. The main treatment period will have participants receive a study drug for a duration of 72 weeks (16 months). If you are eligible, the extended treatment period will allow you to continue taking the study drug for up to 8 years.

Reimbursement for reasonable travel expenses may be provided. All study-related care, including the study drug, is provided at no cost.
