Arimoclomol in Sporadic Inclusion Body Myositis

November 22, 2016 updated by: Richard Barohn, MD

Safety and Tolerability Trial of Arimoclomol for Sporadic Inclusion Body Myositis

Inclusion body myositis (IBM) is the most common progressive and debilitating muscle disease beginning in persons over 50 years of age. This study will assess the safety and tolerability of Arimoclomol in IBM as compared to placebo over 4 months of treatment.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

IBM is a chronic disorder in which muscles become inflamed (swollen) and cause muscle weakening. The cause is unknown. There is new evidence to suggest that the pathology in IBM results from cellular changes induced by a variety of stressful events and diseases. In response to these stressful events the body's normal response is to increase the levels of Heat Shock Proteins (HSP) to help counteract and stop these cellular changes. In people with IBM this increase does not appear sufficient enough to reverse these toxic cellular changes. Arimoclomol causes the body to make more of this HSP protein. By increasing HSP levels in IBM patients we hope to reverse the toxic cellular changes that might be responsible for the pathology of IBM.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

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
Count of Adverse Events Reported
Time Frame: Month 12
Measure reflects the total number of adverse events reported during course of the study.
Month 12

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.
