Optimizing Treatment on Idiopathic Inflammatory Myopathies

December 4, 2024 updated by: Samuel Katsuyuki Shinjo, PhD, University of Sao Paulo

As a T2T, our patients with idiopathic inflammatory myopathies will receive pulse therapies with methyprednisolone and/or human intravenous immunoglobulin, or only methyprednisolone at disease onset.

This scheme is an internal routine protocol of our Service.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

To compare two groups of patients as described in Brief Summary.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Physician Global Activity
Time Frame: Six months
This partially validated tool measures the global evaluation by the treating physician of the overall disease activity of the patient at the time of assessment using a 10 cm. visual analogue scale and a 5 point Likert scale.
Six months
Patient/Parent Global Activity -
Time Frame: Six months
This partially validated tool measures the global evaluation by the patient, or by the parent if the patient is a minor, of the patient's overall disease activity at the time of assessment using a 10 cm. visual analogue scale.
Six months
Manual Muscle Testing
Time Frame: Six months
This partially validated tool assesses muscle strength using manual muscle testing (MMT). A 0 - 10 point scale is proposed for use. An abbreviated group of 8 proximal, distal, and axial muscles performs similarly to a total of 24 muscle groups, and is also proposed for use for research studies.
Six months
Health Assessment Questionnaire
Time Frame: Six months
Define the health assessement questionnaire. Pontuaction: 0.00-3.00
Six months
Muscle Enzymes
Time Frame: Six months
This partially validated tool measures the serum activities of at least 2 of the 4 muscle-associated enzymes including creatine phosphokinase (CK), the transaminases (ALT, AST), lactate dehydrogenase (LD) and aldolase.
Six months
Myositis Disease Activity Assessment Tool
Time Frame: Six months
After local anesthesia, a cutaneous incision will be made in lateral thigh face. The biopsy will be done using the Bergstrom needle. Histological (hematoxylin and eosin)/immunohistochemical (CD4, CD8, CD68, CD20, C5b-9, MHCI, MHCII, CD31) analysis will be performed in muscle samples (at baseline and after 12 weeks) in all patients (present study)
Six months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Side effects to treatment (glucocorticoid, immunosuppressants and/or human intravenous immunoglobulin)
Time Frame: Six months
Effect of drugs in disease outcomes
Six months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2005

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
