简要总结
This study will assess the safety and efficacy of H.P. Acthar gel for treating the cutaneous manifestations in patients with refractory classic dermatomyositis, juvenile dermatomyositis, and amyopathic dermatomyositis. Our hypothesis is that H.P. Acthar gel will be both safe and effective for such patients.
详细描述
Adult and juvenile dermatomyositis (DM) are systemic immune-mediated inflammatory diseases most commonly affecting the skin and musculoskeletal system. Amyopathic dermatomyositis is a subtype of dermatomyositis that affects only the skin and lacks the characteristic muscle involvement. Treatment of these conditions, in particular the cutaneous manifestations, is challenging and currently no universally effective single treatment exists. Many patients have cutaneous manifestations that are refractory to numerous medications.
H.P. Acthar gel (adrenocorticotropic hormone gel) received FDA approval for treatment of a variety of diseases, including dermatomyositis, in 1952. Despite this there is a paucity of clinical data concerning the efficacy of H.P. Acthar gel for treating dermatomyositis. Recently a small, retrospective case series describing significant improvement in both cutaneous and musculoskeletal symptoms in 5 patients with refractory dermatomyositis treated with H.P. Acthar gel was reported and has resulted in renewed interest in use of this medication in dermatomyositis patient (reference below). The proposed efficacy of H.P. Acthar gel has been attributed to its unique ability to induce production of endogenous cortisol, corticosterone, aldosterone, and to bind melanocortin receptors on lymphocytes and other cells to modulate immunologic responses.

入选标准
- •Must be 18 years of age or older with refractory cutaneous symptoms related to either classic dermatomyositis (CD), juvenile dermatomyositis (JD), or amyopathic dermatomyositis(AD). Diagnosis will be based on either Bohan and Peter criteria (CD and JD) or Sontheimer's criteria (AD)
- •Must have had a skin biopsy with histologic features consistent with dermatomyositis and current cutaneous manifestations consistent with dermatomyositis.
- •Although not mandatory, patients with evidence of current or previous active myositis will be eligible for enrollment. Patients will be considered to have refractory disease if cutaneous manifestations exist despite treatment with steroids and at least one steroid-sparing systemic treatment commonly found to be useful in patients with dermatomyositis. These may include azathioprine, cyclosporine, mycophenolate mofetil, IVIG, methotrexate, cyclophosphamide, chlorambucil, sirolimus, adalimumab, infliximab and rituximab.
- •Use of topical medications and sunscreen currently and in past will be noted but not weighed for assessment of refractory cutaneous disease.
排除标准
- •Patients with dermatomyositis who have minimal-to-no active cutaneous features (focal involvement with less than 1% total body surface area involved or minimal modified CDASI activity score).
- •Patients whose cutaneous findings are not consistent with dermatomyositis and/or have previous biopsy results suggestive of an alternative diagnosis
- •Patients with inflammatory myositis other than dermatomyositis, such as polymyositis or inclusion body myositis.
- •Patients with malignancy-associated dermatomyositis
- •Patients with clear features of an overlap myositis
- •Patients younger than 18 years old
- •Patients with acutely active or chronic infections.
- •Patients with uncontrolled diabetes, hypertension, cardiovascular, hepatic, or renal disease
- •Pregnant or lactating females.
- •Patients with any medical condition that is felt by the primary investigator to place the patient at unreasonable risk for adverse effects during treatment with H.P. Acthar.
- •Hypersensitivity to H.P. Acthar, any of its components (allergy to pig-derived proteins)
- •Patients with osteoporosis
- •Patients who have had surgery within 8 weeks of screening
- •Patients with a history of or current gastric ulcers
- •Patients taking daily doses of systemic corticosteroids greater than the equivalent of 40mg prednisone.

80 U (1 mL) of H.P. Acthar gel via subcutaneous injection twice weekly for 24 weeks
干预措施: H.P. Acthar Gel (Drug)
结局指标
主要结局
Change in Physician's Global Assessment (PGA) Visual Acuity Score From Baseline to 6 Months
时间窗: 6 months
Change from baseline to 6 months in Physician's Global Assessment (PGA) visual acuity score. Scores range from 0-10 with Higher scores reflecting severe disease activity.
Change From Baseline in Cutaneous Dermatomyositis at 6 Months
时间窗: 6 months
Change between baseline at 6 months in modified CDASI-A (Cutaneous Dermatomyositis Disease Area and Severity Index) scores at these timepoints. The CDASI-A score ranges from 0 to 100 with higher scores reflecting more severe disease activity.
次要结局

- Change From Baseline in Patient Assessment of Dermatomyositis at 6 Months.(6 months)
- Change From Baseline in Patient Assessment of DLQI Dermatomyositis at 6 Months(6 months)
