A Study to Evaluate the Safety and Efficacy of Apremilast in the Treatment of Skin Disease in Patients With Dermatomyositis
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

ClinicalTrials.gov Identifier: NCT01140503
(Slow recruitment of participants)
The Primary Endpoint Analysis Will be Safety, as Measured by the Number of Adverse Events and Serious Adverse Events Occuring During 12 Weeks of Therapy and 4 Weeks of Followup. [ Time Frame: 16 weeks ]
Secondary Outcome Measures
The Secondary Outcome Measure Will be Efficacy, as Measured by the Number of Participants Experiencing a 30% Decreased in the CDASI-a Score at 12 Weeks. [ Time Frame: Data collected at 12 weeks after baseline visit. ]
This was an intent to treat analysis--dropouts are considered treatment failures. Missing data at 12 weeks imputed by last observation carried forward.
The Secondary Outcome Measure Will be Efficacy as Measured by the Mean Change in CDASI-activity at 12 Weeks [ Time Frame: Data collected at baseline at 12 weeks ]
The CDASI (Cutaneous Dermatomyositis Activity and Severity Index) is a validated instrument to measure skin disease activity in dermatomyositis. A clinically meaningful change is a decrease of 4 points. All missing data are imputed using last observation carried forward. Calculation is performed as the score at 12 weeks minus the score at baseline.

Accepts Healthy Volunteers:
Must understand and voluntarily sign an informed consent form
Must be 18 years at time of signing informed consent form
Must be able to adhere to the study visit schedule and other protocol requirements
Patients must have a diagnosis of DM based upon the characteristic cutaneous findings proposed by Sontheimer1 and a skin biopsy consistent with DM
Subjects must be a candidate for systemic therapy for their DM skin disease: a subject is considered a candidate, if, in the judgment of the investigator, they are not adequately responding to aggressive sun protection along with the use of potent (e.g. class I or II) topical corticosteroids and/or immunomodulators
Must have cutaneous disease activity of at least "moderate" on a 5 point Likert scale (using the PGA)
Must have cutaneous disease activity score of at least 5 on the CDASI (activity) scale
Concurrent therapy with topical corticosteroids and/or prednisone and/or antimalarials is permitted as defined in Exclusion Criteria.
Concurrent therapy with methotrexate azathioprine, mycophenolate mofetil, or leflunomide is permitted as defined in Exclusion Criteria
Must meet the following laboratory criteria:
Hemoglobin ≥ 12 g/dL
White blood cell (WBC) count ≥ 3000 /uL (≥ 3.0 X 10^9/L) and < 14,000/uL (< 14 X 10^9/L)
Platelets ≥ 100,000 /uL (≥ 100 X 10^9/L)
Aspartate transaminase (AST [serum glutamic oxaloacetic transaminase, SGOT]) and alanine transaminase (ALT [serum glutamate pyruvic transaminase, SGPT]) ; 1.5x upper limit of normal (ULN) unless, in the opinion, of the investigator, the elevation is secondary to active muscle inflammation.
Females of childbearing potential (FCBP) must have a negative urine pregnancy test at screening (Visit 1). In addition, sexually active FCBP must agree to use TWO of the following adequate forms of contraception while on study medication: oral, injectable, or implantable hormonal contraceptives; tubal ligation; intrauterine device; barrier contraceptive with spermicide; or vasectomized partner. A FCBP must agree to have pregnancy tests every 28 days while on study medication.
Males (including those who have had a vasectomy) must agree to use barrier contraception (latex condoms) when engaging in sexual activity with FCBP while on study medication and for 84 days after taking the last dose of study medication

History of inadequate response to thalidomide for dermatomyositis skin disease.
Receiving topical therapy within 14 days of Study Day 0 (including but not limited to topical corticosteroids, tacrolimus, pimecrolimus). Exceptions: low potency corticosteroids will be allowed as background therapy for treatment of the face and scalp as needed, but dose must be stable 14 days prior to Study Day 0 and throughout the study
Concurrent therapy with prednisone (or equivalent dose of systemic corticosteroid) at greater than 10 mg daily.
