Predictor of Clinical Response to Acthar in Myositis

Completed

• Conditions: Dermatomyositis; Myositis; Polymyositis
• Interventions: Other: Healthy Control; Other: Myositis in Remission

• Registration Number: NCT03414086
• Lead Sponsor: University of Pittsburgh

Brief Summary

Comparing the clinical effects of Acthar Gel before and after treatment and compare it to patients with inactive disease.

Detailed Description

To compare the clinical impact of Acthar Gel at the cellular and molecular level before and after treatment and compare it to patients with inactive disease. The cohort of active myositis subjects are not actually enrolled in this study, but rather the data for those with active myositis will be obtained from a previously completed trial entitled "Efficacy and safety of Adenocorticotropic Hormone Gel in Refractory dermatomyositis and polymyositis".

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 20

Inclusion Criteria

• Healthy Controls:

  • An individual will be eligible to be a control subject if his/her age is 18 years or greater.

• Myositis Remission Control Group

  • Definite or probable PM or DM by Bohan and Peter criteria.
  • PM patients must either possess a myositis-associated autoantibody or undergo adjudication for confirmation of the PM diagnosis by consensus of two experts (Aggarwal or Oddis) to ensure non-PM patients are not enrolled. This step is necessary since there are well known mimics of PM.
  • Age is greater than or equal to 18 years
  • Remission of myositis as defined by a myositis disease global activity score <1 on the MDAAT and no new immunosuppressive or glucocorticoid therapy or dose change within one year.

Exclusion Criteria

• Healthy Controls:

  • An existing diagnosis of a CTD
  • A potential immune compromised state, for example, treatment with immunosuppressant or anti-rejection medication or a diagnosis of an immune deficiency disease

• Myositis Remission Control Group:

  • Juvenile DM or PM, myositis in overlap with another connective tissue disease, cancer associated myositis, inclusion body myositis, or any other non immune mediated myopathy.
  • Severe muscle damage defined as a baseline global muscle damage score on the MDI (Myositis Damage Index) of greater than or equal to five centimeters on a ten centimeter VAS.
  • Patients with malignancy within three years of screening (except basal cell cancer or squamous cell cancer of skin.
  • Uncontrolled diabetes, hepatic or renal disease.

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Arm && Interventions

Group	Intervention	Description
Healthy Controls	Healthy Control	Subjects who do not have a myositis diagnosis.
Myositis in Remission	Myositis in Remission	Subjects who are in remission with their myositis diagnosis.

Primary Outcome Measures

Name	Time	Method
IMACS Core Set Measures Improvement	6 Months	The International Myositis Assessment \& Clinical Studies (IMACS) definition of improvement: Three of any of the six core set measures improved by greater than or equal to twenty percent, with no more than two core set measuring by greater than or equal to twenty five percent.

Secondary Outcome Measures

Name	Time	Method
Myositis Response Criteria	6 Months	This criteria yields a continuous improvement score which can be more readily extrapolated to individual response in subjects allowing correlation with baseline and longitudinal immunologic markers in these subjects.
