Long-term, Open-label, Safety Study of Inebilizumab in Neuromyelitis Optica Spectrum Disorder (NMOSD)
United States, China, Czechia32 participantsStarted 2024-04-02
Plain-language summary
The purpose of this study is to understand the effects of long-term treatment with inebilizumab on circulating levels of immunoglobulins, B-cell counts, and other safety measures, and to further monitor repletion of immunoglobins and B-cell counts in participants with NMOSD who discontinue treatment. The objectives include:
1. To establish the nadir in circulating immunoglobulins (Ig) during chronic treatment with inebilizumab and ascertain the time needed to ensure restoration of pre-treatment baseline serum levels of IgG and IgM after discontinuation of treatment
2. To characterize B-cell counts throughout treatment with inebilizumab and after discontinuation until repletion of Immunoglobulin (Ig levels)
3. To assess long-term safety of inebilizumab
4. To assess other long-term effects of inebilizumab

Inclusion criteria
. Age 18 years or above, and able to provide written informed consent and any locally required authorization (e.g., Health Insurance Portability and Accountability Act \[HIPAA\] in the United States of America (USA), European Union \[EU\] Data Privacy Directive in the EU) obtained from the subject/legal representative prior to performing any protocol-related procedures, including screening evaluations.
. Have completed at least 2 years in the open-label period of the N-MOmentum study or are newly initiating inebilizumab treatment at a participating site.
. Females of childbearing potential who are sexually active with a nonsterilized male partner must use a highly effective method of contraception as outlined in the protocol (subjects in the Czech Republic only must use 1 additional method of contraception) from screening, and must agree to continue using such precautions for 6 months after treatment with inebilizumab; cessation of contraception after this point should be discussed with a responsible physician.
. Nonsterilized males who are sexually active with a female partner of childbearing potential must use a male condom plus spermicide (subjects in the Czech Republic only must use 1 additional method of contraception) from Day 1 for 3 months after receipt of last treatment with inebilizumab.
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.
What they're measuring
1
Change from baseline in serum Ig levels (total Ig, IgG, IgM, IgA, IgE) over time
Timeframe: Up to 42 months
2
Change from baseline in peripheral CD20+ B-cell counts over time
. Sterilized males, without the appropriate post-vasectomy documentation on the absence of sperm in the ejaculate, who are sexually active with a female partner of childbearing potential must use a condom and spermicide from Day 1 for 3 months after receipt of the last treatment with inebilizumab.
Exclusion criteria
. Have any condition that would place the participant at unacceptable risk of complications, interfere with evaluation of inebilizumab or confound the interpretation of participant safety or study results.
. Received rituximab or any other B-cell depleting agent after exit from N-MOmentum study, or within the last 12 months prior to screening for non N-MOmentum participants.
. Known history of allergy or reaction to any component of inebilizumab formulation or history of anaphylaxis following any biologic therapy
. Have a severe clinically significant infection, including active chronic infection such as hepatitis B
. Have active or untreated latent tuberculosis
. Have a history of progressive multifocal leukoencephalopathy (PML)
