We conduct this study to investigate the efficacy of triple therapy (high-dose glucocorticoids + cyclophosphamide + calcineurin inhibitor) compared with dual-therapy regimens (high-dose glucocorticoids + cyclophosphamide/calcineurin inhibitor) and whether it reduces the risk of poor pulmonary prognosis in patients with moderate to high risk anti-MDA5+ DM.
Anti-melanoma differentiation-associated gene5 (Anti-MDA5) antibody positive Dermatomyositis (DM) is a subtype of DM that is more frequent in East Asia, which is often exhibit skin lesion, clinically amyopathic and interstitial lung disease. About 42%-100% of patients with Anti-MDA5+ DM develop rapidly progressive interstitial lung disease (RPILD) and result in respiratory failure. The mortality is as high as 40% within 6 months. In addition, not every patient with Anti-MDA5+ DM respond to traditional treatment strategy and most of the patients are resistant to immunosuppressive therapy including a combination of high dose glucocorticoids (GCs) and immunosuppressants such as cyclosporine, tacrolimus, or cyclophosphamide. However, RP-ILD is still the main cause of death due to fatal respiratory failure. Therefore, treatment of Anti-MDA5+ DM patients is challenging.Blocking multiple cytokines may become a new target for the treatment of this disease.Jakinibs is a Janus kinase (JAK) inhibitor that blocks a variety of cytokines, such as type I and type II interferon. Few studies have reported a positive response to JAK inhibitor for Anti-MDA5+ DM. Kazuhiro et al. reported in 2018 that JAK inhibitor tofacitinib may be an effective treatment option for high risk amyopathic dermatomyositis (ADM) -ILD patients after failure of conventional treatment, but the number of cases is too small. And a recent paper showed that great efficacy of tofacitinib for the improvement of survival of anti-MDA5-positive early-stage ADM-ILD patients.The aim of this study is to evaluate the efficacy and safety of JAK inhibitors in the treatment of anti-MDA5+ DM patients, and to evaluate the effect of JAK inhibitors on B cells of these patients, so as to provide a new target and theoretical basis for the treatment of anti-MDA5+ DM.
With limited treatment options available for dermatomyositis, the investigators hypothesize that apremilast, a phosphodiesterase-4 (PDE-4) inhibitor, is a safe and efficacious add-on treatment in patients with refractory cutaneous dermatomyositis. The study will investigate the efficacy, safety and toxicity of apremilast given at 30 mg twice daily to patients with refractory cutaneous dermatomyositis. Clinical response will be assessed at 1 and 3 months. Patients will also be evaluated for durability of their response for up to 6 months. Treatment will be monitored with frequent clinical visits (0, 1, 3 and 6 months) and blood tests (CBC, CMP, creatine kinase, aldolase). Treatment will be discontinued at disease progression or unacceptable adverse events. Disease progression is defined as 4 points increase in the cutaneous dermatomyositis disease area and severity index (CDASI) score, worsening of muscle disease by manual muscle testing (MMT-8) score and 5 points increase in dermatomyositis life quality index (DLQI). 5 mm skin biopsies from lesional skin will be performed before treatment with apremilast and after 3 months of treatment for gene expression profiling and confirmatory immunohistochemical stains.
