Official Title  ICMJE A Prospective, Randomised, Assessor-blind, Multicenter Study of Efficacy and Safety of Combined Treatment of Methotrexate + Glucocorticoids Versus Glucocorticoids Alone in Patients With Polymyositis and Dermatomyositis.
Brief Summary

Therapeutical trial in patients with idiopathic polymyositis (PM) and dermatomyositis (DM) is proposed. The study will investigate the safety and efficacy of combined methotrexate (MTX) + glucocorticoids (GC) treatment compared with GC alone.

This will be a randomised, open-label, assessor-blind, international multicenter trial, performed in several European centres interested in research on inflammatory myopathies (IIM).

A total number of 50 patients with PM/DM will be randomised into two groups (1: MTX+ GC and 2: GC only). Patients will be equally distributed between the two groups providing 25 patients per treatment arm. The randomisation will be based on random numbers generated by a computer program. After being enrolled in the study, the patients will receive 12 months of therapy followed by a 12-month follow-up period.

The primary endpoint is the total dose of GC ( in mg/kg weight), which will be administered for 12 months between baseline and the end of treatment.

There are several of secondary objectives, which will be pursued during and after the trial. Disease activity and damage will be prospectively assessed by tools for myositis disease activity (MYOACT and MITAX) and for myositis damage (MYODAM and MDI), global assessment of activity and damage by patients and by physician, muscle endurance, muscle strength by manual muscle testing, enzyme levels, GC related side effects, functional ability measured by HAQ, quality of life by SF-36, and number of patients with treatment failures. The other aims will also include (i) search for reliable prognostic parameters in the further prognosis of patients with PM/DM and (ii) studies on the pathogenic aspects of IIM. The investigations of serum, lymphocytes, muscle tissue and MRI will be organized. DNA and RNA will be stored for future genetic studies.

Patients with definite or probable PM or DM diagnosed according to diagnostic criteria will be enrolled. They will have disease activity that according to physician's own judgement requires high dose immunosuppressive treatment (based on clinical assessment of weakness, elevation of muscle enzymes and, if available, on magnetic resonance imaging findings). Patients should be previously untreated with the exception of GC treatment up to 8 weeks.

Patients with other than primary idiopathic PM or DM, such as drug-induced myositis, myositis in association with other connective tissue disease, inclusion body myositis, malignancy related myositis, and juvenile DM will be excluded.

All patients will start with prednisone 1 mg/kg/day and the dose will be tapered if patients meet definition of improvement, which has been proposed by IMACS group. MTX will be administered orally, once weekly, with a starting dose 10 mg. This will be increased gradually to 25 mg/week if tolerated by week 5. Patients will be first assessed after 2 weeks and than monthly for a period of 48 weeks. There will be a follow-up after a further 1 year in order to find out the impact of the early treatment on the long-term disease outcome.

All efficacy analyses will be performed using intention-to-treat population (ITT). In addition, the primary and secondary variables will be analysed using the per-protocol population, which will contain all patients in the ITT population, who also reached Week 48 without any major protocol violations. The safety population, which will contain any patient who received at least one dose of study drug, will be used for all safety analyses.

Detailed Description

Clinical trial:

A prospective, randomized, assessor- blind, multicenter study of safety and efficacy of combined treatment of methotrexate and glucocorticoids versus glucocorticoids alone in patients with polymyositis and dermatomyositis

Tested investigational medicinal product: Methotrexate (Methotrexatum dinatricum 2,5 mg tbl.).

Mechanism of Action: Methotrexate inhibits dihydrofolic acid reductase. Dihydrofolates must be reduced to tetrahydrofolates by this enzyme before they can be utilized as carriers of one-carbon groups in the synthesis of purine nucleotides and thymidylate. Therefore, methotrexate interferes with DNA synthesis, repair, and cellular replication. Actively proliferating tissues such as malignant cells, bone marrow, fetal cells, buccal and intestinal mucosa, and cells of the urinary bladder are in general more sensitive to this effect of methotrexate.

Comparator : Prednison (Prednisonum 20 mg tbl.)

Mechanism of Action: Glucocorticoids are naturally occurring hormones that prevent or suppress inflammation and immune responses when administered at pharmacological doses. At a molecular level, unbound glucocorticoids readily cross cell membranes and bind with high affinity to specific cytoplasmic receptors. This binding induces a response by modifying transcription and, ultimately protein synthesis to achieve the steroid's intended action. Such actions may include: inhibition of leukocyte infiltration at the site of inflammation, interference in the function of mediators of inflammatory response, and suppression of humoral immune responses. Some of the net effects include reduction in edema or scar tissue, as well as a general suppression in immune response. The degree of clinical effect is normally related to the dose administered. The antiinflammatory actions of corticosteroids are thought to involve phospholipase A2 inhibitory proteins, collectively called lipocortins. Lipocortins, in turn, control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of the precursor molecule arachidonic acid. Likewise, the numerous adverse effects related to corticosteroid use are usually related to the dose administered and the duration of therapy.

Number of patients in the trial:

  • Total 50
  • In this centre: 10

Summary:

The aim of the study is to determine the safety and efficacy of adding methotrexate (MTX) to glucocorticoids (GC) compared with glucocorticoid treatment alone in patients with inflammatory myopathies.

  1. PM and DM are usually treated with glucocorticoids and immunosuppressive drugs. However, such treatment has not yet been studied thoroughly and properly evaluated in a randomized controlled trial. There are only few controlled studies of PM/DM management and all of them have been performed in small groups of patients. This will be the first randomized controlled trial with MTX
  2. This clinical trial will assess efficacy MTX in patients with early PM/DM
  3. Also long- term effect of treatment (MTX and glucocorticoids versus glucocorticoids) will be evaluated.
  4. Inclusion criteria allow to follow up the consistent group of PM/DM patients.
  5. In this trial the of newly developed tools for myositis disease activity will be used
  6. The secondary objectives is to study pathogenic aspects of inflammatory myopathies.
  7. The serum, DNA and RNA will be stored for future genetic studies and to study autoantibodies to search for prognostic markers.

Objectives:

The primary objective of the study is to determine the safety and efficacy of adding methotrexate (MTX) to glucocorticoids (GC) compared with glucocorticoid treatment alone in patients with inflammatory myopathies. The primary endpoint that will be measured is the total dose of glucocorticoids (in mg/kg weight) administered between baseline and the end of treatment.

The secondary objectives are:

  1. Assessment of disease activity and damage [with the use of newly developed tools for myositis disease activity (MYOACT and MITAX) and myositis damage (MYODAM and MDI), as well as by global assessment of activity and damage by patients and by physician.
  2. Muscle strength by manual muscle testing
  3. Muscle endurance
  4. Muscle enzyme levels
  5. Glucocorticoid related side-effects
  6. Final glucocorticoid dose
  7. Disability index by HAQ
  8. Quality of life by SF-36
  9. Number of patients with treatment failures
  10. Search for reliable prognostic parameters in the further prognosis of patients with inflammatory myopathies.

Study of the pathogenic aspects of inflammatory myopathies. Therefore investigations of serum, lymphocytes, muscle tissue and MRI will be organized. DNA and RNA will be stored for future genetic studies.

Study design.

This will be a randomized, assessor-blinded, multicenter, international study. After being enrolled in the study, the patients will receive 48 weeks of therapy followed by a 12-month follow-up period.

A total number of 50 patients with polymyositis/dermatomyositis are planned to be randomized. These will be equally distributed between the two groups providing 25 patients per treatment arm. Patients will be randomized on the basis of random numbers generated by a computer program.

Indication:

Treatment of active polymyositis and dermatomyositis

Evaluations.

Efficacy. The efficacy will be assessed by fulfillment of definition of improvement at every visit and treatment taper with glucocorticoids. Overall efficacy will be assessed by measurement of disease activity (MITAX, MYOACT), disease damage (MDI, MYODAM), global patient's and physician's assessments, manual muscle strength test, functional muscle test2, health assessment questionnaire (HAQ), and SF36.

Safety.

The safety will be assessed at every visit by clinical and laboratory examinations. Specifically, clinical assessment will include physical examination, vital signs, muscle function index, manual muscle strength test, MYOACT, MITAX, MYODAM, MDI, HAQ and global assessment of activity and damage by physician and patient.

Laboratory assessments will include complete blood count, blood chemistry including SGOT (AST), SGPT (ALT), Na, K, creatinine, LDH, CK, CRP and urine pregnancy test if required by local practice.

In patients with pulmonary alveolitis or interstitial fibrosis at the start of the study - HRCT should be performed. If significant progress of pulmonary infiltrate will occur, this is considered to be treatment failure and patient will be treated according to standard approach.

Pulmonary toxicity from methotrexate can be suspected in patients with sudden onset of nonproductive cough with dyspnea. HRCT should be performed. If there are no other obvious reasons for these symptoms methotrexate should be discontinued.

If nausea after methotrexate occurs, try to divide the dose or give antinauseous drug. If there are still unacceptable gastrointestinal side effects, parenteral methotrexate administration can be considered.
