Brief Summary

The purpose of the study is to obtain preliminary data regarding the safety and tolerability of etanercept in DM. In addition, we will use the study to assess the variability, reliability, and responsiveness of the core set of outcome measures recommended by IMACS. The study will be performed under the aegis of the Muscle Study Group (MSG), consisting of experienced investigators with an avid interest in myopathies. The ultimate goal of this pilot study will be to obtain necessary, prerequisite information important in designing future therapeutic trials of etanercept and other agents in patients with DM. The specific aims of the study are: Aim 1: To preliminarily assess the safety and tolerability of etanercept in patients with DM. Aim 2: To assess the safety and tolerability of prednisone in the dosing schedule we propose to use. Aim 3: To evaluate outcome measures recommended by IMACS and assess their variability, reliability, and responsiveness in order to facilitate the design of future therapeutic trials in the inflammatory myopathies.

Outcome Measures

Primary Outcomes (26)

• Occurrence of at Least One Adverse Event

  Adverse events (AEs) were assessed using the Common Terminology Criteria for Adverse Events version 3.0 (CTCAE). The grade of "mild", "moderate" or "severe" matches with the descriptions from the CTCAE dictionary. In general, a "Mild" AE is asymptomatic; clinical or diagnostic observations only; intervention not indicated. A "Moderate" AE is minimal, local or noninvasive intervention indicated; limiting activities of daily living. A "Severe" AE is medically significant but not immediately life-threatening; hospitalization or prolonged hospitalization indicated; disabling;

  at each visit during the 12 month study

• Tolerability

  The reported tolerability measure was defined as the number of participants that completed the entire 52 week study on their originally assigned treatment.

  At any point between Baseline (week 0) and the end of the study (Week 52)

• Average Change in Oral Temperature From Baseline to Week 52

  The subject's oral temperature was measured in degrees Celsius. The average change was determined by subtracting the Baseline Visit (Week 0) results from the Week 52 results (Week 52- Baseline (Week 0)). This measure was also collected as part of the study protocol at the Screening visit and Week 4,8,12,16,20,24,32 and 40.

  At Baseline (Week 0) and Week 52

• Average Change in Respiration Rate From Baseline to Week 52

  The subject's respiration rate was measured as number of breaths per minute. The average change was determined by subtracting the Baseline Visit (Week 0) results from the Week 52 results (Week 52- Baseline (Week 0)). This measure was also collected as part of the study protocol at the Screening visit and Week 4,8,12,16,20,24,32 and 40.

  At Baseline (Week0) and Week 52

• Average Change in Systolic Blood Pressure From Baseline to Week 52

  The subject's systolic blood pressure was measured in millimeters of mercury (mmHg). The average value was calculated per treatment group for the Baseline and Week 52 visit based on treatment group. The average change was determined by subtracting the average value Baseline Visit (Week 0) results from the Week 52 results (Week 52- Baseline (Week 0)). This measure was also collected as part of the study protocol at the Screening visit and Week 4,8,12,16,20,24,32 and 40.

  At Baseline (Week0) and Week 52

• Average Change in Diastolic Blood Pressure Comparing Baseline to Week 52.

  The subject's diastolic blood pressure was measured in millimeters of mercury (mm Hg). The average value was calculated for the Baseline and Week 52 visit based on treatment group. The average change was determined by subtracting the average value Baseline Visit (Week 0) results from the Week 52 results (Week 52- Baseline (Week 0)).

This measure was also collected as part of the study protocol at the Screening visit and Week 4, 8, 12, 16, 20, 24, 32 and 40.

  At Baseline (Week0) and Week 52

• Average Change in Body Weight in Kilograms (kg) Comparing Baseline to Week 52.

  The subject's body weight was measured in kilograms(kg). The average value was calculated for each treatment group for the Baseline and Week 52 visits.
