Overview

The RMD-mILDer trial is a home monitoring strategy trial aiming to improve management of interstitial lung disease related to rheumatic diseases applying eHealth technology.

It is planned as a 2 arm 54 week multi-centre randomised controlled trial to assess outcome of home monitoring with bi-weekly serial forced vital capacity- and patient reported outcome-measurements compared to standard of care with fixed-interval hospital visits in adult patients with rheumatic disease associated interstitial lung diseases.

Eligibility

Inclusion Criteria:

• Systemic rheumatic disease (Systemic sclerosis (SSc), rheumatoid arthritis (RA), idiopathic inflammatory myopathies including antisynthetasis syndromes (IIM), mixed connective tissue disease (MCTD) or Sjøgrens disease (SjD)) classifiable by disease-specific classification criteria
• Diagnosed interstitial lung disease (ILD) on high resolution computed tomography (HRCT) ≥ 1 year prior to randomization, not explained by other diseases or exposures
• On stable standard of care treatment 6 months prior to randomization
• Participants must be able to understand and follow trial procedures including completion of questionnaires regarding Patient Reported Outcome measures
• Participants must have access to the internet, and experience in using smartphones or other electronic devices with internet access
• Signed informed consent form

Exclusion Criteria:

• Severe heart failure with ejection fraction (EF) < 30%
• Chronic renal failure G4 or more (defined by KDIGO) with glomerular filtration rate (eGFR) < 30 mL/min using Cockroft-Gault formula.
• End stage lung disease with forced vital capacity (FVC) < 50% and/or diffusion capacity for carbon monoxide (DLCO) < 40% or coexisting severe other lung diseases (e.g. chronic obstructive pulmonary disease, emphysema)
• Airway obstruction (pre-bronchodilator FEV1/FVC < 0.7) (FEV1 is defined as forced expiratory volume in 1 sec)
• In the opinion of the investigator, other clinically significant pulmonary abnormalities
• Significant pulmonary hypertension defined by the following: Previous clinical or echocardiographic evidence of significant right heart failure OR history of right heart catheterization showing a cardiac index </= 2 L/min/m2 OR pulmonary hypertension requiring therapy with epoprostenol/treprostinil
• Active treatment for cancer or non-curable cancer
• Relative contraindications to performing spirometry, as specified in ATS/ERS guidelines.
• Ongoing Prednisolone ≥ 20 mg/day at inclusion
• Unable to speak, write and read Norwegian, German or Romanian in the respective country of inclusion.
• Unable to perform good quality measurements of FVC on the home-device comparable to results on an in-hospital device, after training.
• Pregnancy or planned pregnancy
