United States47 participantsStarted 2014-09-30

Plain-language summary

The primary objective of the study is to determine the efficacy of natalizumab (Tysabri, BG00002) in participants with relapsing forms of multiple sclerosis (MS) who have failed Gilenya or BRACET (Betaseron, Rebif, Avonex, Copaxone, Extavia, Tecfidera) as measured by the proportion of participants with no evidence of disease activity (NEDA) at Year 1. The secondary objectives in this study population are: change in total T1 hypointense and total T2 hyperintense lesion volume; proportion of participants with NEDA at Year 2; evaluation of the impact of natalizumab on annualized relapse rate (ARR); and change in Multiple Sclerosis Impact Scale-29 (MSIS-29) physical impact score.

Key Inclusion Criteria: * Subjects of childbearing potential must practice effective contraception from Day -1 and be willing and able to continue contraception for duration of the study. * Must have documented diagnosis of relapsing MS (McDonald 2010 Criteria \[Polman 2011\]) at Screening. * Must have been treated with Gilenya or Betaseron, Rebif, Avonex, Copaxone, Extavia, Tecfidera (BRACET) for at least the 12 months prior to Screening with no interruption of treatment greater than 1 month. Prior treatment with natalizumab is allowed; however, there must be a minimum 1 year since last natalizumab infusion and the Screening visit of this study, and if discontinuation of natalizumab in the past was not due to intolerance, anti-natalizumab antibodies, or efficacy loss. * Must have had disease activity in the 6 months prior to Screening while on Gilenya or BRACET (as defined by at least 1 gadolinium enhancing lesion OR at least 2 new T2 lesions compared with magnetic resonance imaging done within 12 months of screening OR clinical relapse, or Expanded Disability Status Scale \[EDSS\] progression of 1 point) * Must have an EDSS score from 0 to 5.5 inclusive at Screening. * Must have lymphocyte count that is documented as at or above the lower limit of normal (LLN) by the day before the first Tysabri infusion. If lymphocytes have not returned to LLN or above the day before the first Tysabri infusion (day 0), the subject has screen failed. The subject who screen fails is eligibl…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
