What is being measured

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

  1. Incidence of Adverse Events

    Adverse events will be evaluated by treating physician.

    Measured: Up to 5 weeks

Secondary outcomes (4)
  1. Efficacy as measured by FSS scores

    Efficacy will be reported as the number of participants that dropped one point or more from their baseline Fatigue Severity Scale (FSS) scores. FSS is a 9-item questionnaire with questions related to how fatigue interferes with certain activities according to a self-reported scale. Each of the items are scored on a 7 point scale with 1 = strongly disagree and 7 = strongly agree.

    Measured: Up to 5 weeks

  2. Efficacy as measured by MFIS Scores

    Modified Fatigue Impact Scale (MFIS) is a scale is used to measure fatigue with the total score ranging from 0 to 84 with 0 being the best possible score and 84 being the worst score.

    Measured: Up to 5 weeks

  3. Efficacy as measured by the VAS scores

    The Visual Analog Scale (VAS) allows participants to rate their health on a 20 cm vertical with a higher number indicating better outcomes.

    Measured: Up to 5 weeks

  4. Efficacy as measured by the MSQOL Scores

    Multiple Sclerosis Quality of Life (MSQOL) has a total score ranging from 0 to 100 with a higher score indicating a better quality of life.

    Measured: Up to 5 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing L-Histidine and Lodosyn in people with Multiple Sclerosis, run by University of Miami at 1 site in United States.

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 7 inclusion and 28 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The record says: withdrawn, as of the sponsor's last update on 29 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Incidence of Adverse Events (time frame: Up to 5 weeks). 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 29 Jul 2021.
