1. Male and female patients between 18-75 years who have been defined as definite or probable” based on the criteria of Bohan and Peter for PM and DM at least three mo before study entry.
2. Patients must demonstrate persisting muscle weakness defined as having a score no greater than 135/150 on the baseline manual muscle testing (maximum MMT-8 score of 150) in conjunction with at least 2 other abnormal IMACS core set measures: Patient VAS with a minimum value of 2.0cm on a 10cm scale. MD global VAS with a minimum value of 2.0cm on a 10cm scale. HAQ disability index (ranging from 0 to 3) with a minimum value of 0.25. Elevation of at least one of the muscle enzymes [includes CK, LDH, ALT and AST] at a minimum level of 1.3 x the upper limit of normal. In case of ALT or AST elevation, other criteria, at the Investigator’s discretion, should be observed to ensure this is not due to liver damage. For the efficacy EP, if more than one muscle enzyme is identified as being elevated and meeting the above guidelines then the most abnormal will be selected and this enzyme will be the target enzyme followed to evaluate disease improvement or worsening. Global extramuscular disease activity score with a minimum value of 1.0 cm on a 10cm VAS scale (this measure is the physician’s composite evaluation and is based on assessments of activity scores on the constitutional, cutaneous, skeletal, gastrointestinal, pulmonary and cardiac scales of the MDAAT.
3. Patients must have received conventional therapies as defined by corticosteroid alone or in combination with DMARDS (MTX, AZA, CyA or MMF) for at least three months before screening.
4. Patients must be on a stable dose of corticosteroid (5-20 mg prednisone or equivalent per day) for at least 2 weeks prior to screening and should not have received a medium or high dose (= 1 mg prednisone or equivalent per body weight kg) corticosteroid therapy in the last 8 weeks prior to study entry.
5. Those patients currently treated with DMARDs must not be responding to DMARD therapy (MTX, AZA, CyA or MMF) defined by proven toxicity or inadequate efficacy as determined by the Investigator. Withdrawal from their DMARDs therapy will occur at least 4 weeks prior to baseline.
6. Female patients of child bearing potential must be using two acceptable methods of contraception (e.g., intra-uterine device plus condom, spermicidal gel plus condom, diaphragm plus condom, etc.), from the time of screening and for the duration of the study, through Study Completion. Period abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception. Postmenopausal females must have had no regular menstrual bleeding for at least one (1) year prior to initial dosing. Menopause will be confirmed by a plasma FSH level of >40 IU/L at screening. Female patients who report surgical sterilization must have had the procedure at least six months prior to initial dosing. Surgical sterilization procedures should be supported with clinical documentation made available to the sponsor and noted in the Relevant Medical History/Current Medical Conditions section of the CRF. All female patients must have negative pregnancy test results at Screening.
7. Male patients must be using two acceptable methods of contraception, (e.g., spermicidal gel plus condom) for the entire duration of the study, up to Study Completion visit, and refrain from fathering a child in the three (3) mo
1. Other types of idiopathic inflammatory myopathies (paraneoplastic PM/DM; juv. myositis (< 18 yrs); DM with no muscle involvement; inclusion body myositis.
2. Overlap PM/DM if muscle symptoms due to other causes (e.g. arthritis cleroderma, steroid induce myopathy +/or signif. organ damage (e.g lupus nephritis, CNS vasculitis). Overlap patients who satisfy Bohan+Peter criteria +signs of autoimmune disease may be eligible.
3. Myopathy due to conditions other than PM/DM.
4. Severe pharyngeal, cardiac, pulmonary involvement; any major internal organ damage which deemed clinically significant.
5. Late-stage PM/DM whose muscle weakness could be attributable to muscle damage rather than to myositis disease activity.
6. Treatment with IGs and/or mAbs within 6 m prior to randomization: rituximab, cyclophosphamide, other immunosuppressive treatments with effects potentially lasting over 6 m, within 12 m prior randomization.
7. Pregnant, planning to get pregnant, and/or lactating females.
8. Participation in any CT within 4 w prior to screening or longer if required locally.
9. History of macular edema, diabetic retinopathy, uveitis, central serous retinophathy, retinal vein occlusion, any other eye disease that increases the risk of macular edema.
10. History or presence of stable or unstable IHD, MI, myocarditis, cardiomyopathy, history of angina pectoris due to coronary spasm, history of Raynaud's disease, cardiac failure at screening (NYHA II-IV) or any severe cardiac disease, history of cardiac arrest or symptomatic bradycardia, resting pulse rate <55 bpm prior randomization, history or presence of a clin. relevant impairment of cardiac conduction incl. sick sinus syndrome, sino-atrial heart block, clin. significant AV block, bundle branch block or an increased QTc > 450 msec for males and > 470 msec for females at the screening or baseline ECG and/or the Screening Holter, symptomatic arrhythmia or arrhythmia requiring treatment or being otherwise of clin. significance, uncontrolled art. HT. Treatment with medication impairing cardiac conduction (e.g., beta blockers, verapamil-type and diltiazem-type calcium channel blockers, or cardiac glycosides), history of syncopes of suspected cardiac origin or catheter ablation.
11. Severe resp. disease or pulm. fibrosis, TB, except for history of successfully treated TB or history of prophylactic treatment after positive PPD skin reaction, abnormal chest X-Ray or HRCT suggestive of active pulm. disease, abnormal Pulmonary Function Tests: FEV1, FVC < 70% of predicted value, pats receiving chronic (daily) therapies for asthma.
12. Significant drug allergy/history of atopic allergy. Hypersensitivity to study drug or similar drugs.
13. History/presence of malignancy (except successfully treated basal or squamous cell carcinoma).
14. Uncontrolled diabetes or diabetes complicated with organ involvement eg. nephro- or retinopathy.
15. Systemic bacterial, viral or fungal infections, or diagnosis of AIDS, HepB, HepC.
16. Other acute or chronic infectious diseases.
17. Negative for varicella-zoster IgG antibodies at screening.
18. Have received any live or live attenuated vaccines within 2 m prior to randomization.
19. Have received total lymphoid irradiation or bone marrow transplantation.
20. Any medically unstable condition
21. Surgical or medical condition significantly altering ADME of drugs or which may jeopardize patient in case of participation in the study. Investigator to be guided by evidence of a
