About this study

Official title: Phase II Trial of Methotrexate in Myasthenia Gravis

Myasthenia gravis is a rare neuromuscular disorder characterized by weakness and fatigability of ocular, bulbar, and extremity musculature. The specific aim of this study is to determine if oral methotrexate is an effective therapy for myasthenia gravis (MG) patients who are prednisone dependent. Patients will be randomized to receive either methotrexate or placebo and those who are entered onto this trial will have symptoms and signs of the disease while on prednisone therapy. The hypothesis is that adding methotrexate therapy in these patients will improve the MG manifestations so that the prednisone dose can be reduced and clinical measures of MG severity will improve.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Total Prednisone Dose Area Under the Curve

    The primary outcome measure was the nine-month prednisone area under the dose-time curve (AUDTC, months 4-12). The AUDTC was chosen because it accounted for changes in the prednisone dose that could occur frequently during a month.

    Measured: 9 months

Secondary outcomes (6)
  1. Average Prednisone Daily Dose (mg/Day)

    Participants were asked to fill out the amount of prednisone they took every day on a paper diary.

    Measured: Total length of time daily dose information was collected, i.e. 9 months.

  2. Quantitative Myasthenia Gravis (QMG) Score

    The QMG is a 13 item ordinal scale which measures ocular, bulbar, extremity fatigue and strength, along with respiratory function. The scale is from 0 - 3 for each item, with 0 meaning normal and 3 is severe. Total score can range from 0 to 39.

    Measured: Change from Baseline to Month 12

  3. Manual Muscle Testing 12 Month Change

    This measurement was developed to measure the strength of muscle groups in the face, neck, arms and legs. Measurement is made by grading the amount of weakness. Participants are graded as having normal, mild (25%) weakness, moderate (50%) weakness or severe (75%) weakness and 4 = paralyzed/unable to do. Normal would receive a score of 0, mild would receive a score of 1, moderate would receive a score of 2, severe would receive a score of 3 and unable to perform would receive a score of 4. Range would be from 0 (no weakness) to 76 (complete paralysis).

    Measured: Change from Baseline to Month 12

  4. MGQOL 12 Month Change

    This test is a 15 item patient-reported scale indicating how myasthenia gravis affects the quality of life. Each item is graded as how true each statement has been over the past 7 days. The scale is 0=Not at all, 1= a little bit, 2= somewhat, 3= quite a bit and 4= very much. The numbers are then added to produce a total score. The MGQOL score would range from 0 (no MG symptoms that affected their quality of life) to a score of 60 (MG symptoms affected they quality of life very much).

    Measured: Change from Baseline to Month 12

  5. MG-ADL 12 Month Change

    The MG-ADL is an 8 item scale developed to assess myasthenia gravis symptoms. Score will range from 0 (normal - no MG symptoms) to 24 (severe MG symptoms)

    Measured: Change from Baseline to Month 12

  6. MG Composite Change Over 12 Months

    This scale is composed of components of the QMG, MG-ADL and the MMT. These components have been shown to be the most responsive in previous clinical trials. Each item in the QMG, MG-ADL and the MMT was weighed (Rasch analysis performed) and then assigned a score. Score would range from 0 (no effects from the myasthenia gravis) to a score of 50. A participant with a score of 50 wwould be in the hospital on a ventilator.

    Measured: Change from Baseline to Month 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Methotrexate in people with Myasthenia Gravis, run by University of Kansas Medical Center at 16 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 16 sites in United States, Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Dec 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Total Prednisone Dose Area Under the Curve (time frame: 9 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 May 2016.
