- Conditions
- Lung Disease, Interstitial
- Interventions
- Registration Number
- NCT02990286
- Lead Sponsor
- University Hospital, Tours
- Brief Summary
The purpose of the study is to evaluate the efficacy on lung function 6 months after one course of rituximab (2 infusions) and mycophénolate mofétil (MMF) treatment compared to one course of placebo and 6 months of MMF treatment in a broad range of patients with Interstitial Lung Diseases (ILD) non-responders to a first line immunosuppressive treatment.

- All
- Target Recruitment
- 122
-
Age ≥ 18 years
-
A diagnosis of ILD:
- ILD associated with differentiated CTD or IPAF (based on internationally accepted criteria)
- OR idiopathic ILD
-
A diagnosis of NSIP based on:
- a histological pattern of NSIP
- OR HRCT findings suggestive of NSIP defined as basal predominant reticular abnormalities with traction bronchiectasis, peri-bronchovascular extension and subpleural sparing, frequently associated with ground-glass attenuation
-
Patients who did not respond or relapsed or were not able to continue at least one first-line immunosuppressive treatment of ILD: corticosteroids, azathioprine, cyclophosphamide or other immunosuppressants. For the assessment of clinical response, the absence of response was defined as: either a decrease or an increase, but <10% in % predicted FVC.
-
Subjects covered by or having the rights to French social security (including CMU),
-
Written informed consent obtained from subject, with a specific check box on the Consent form of the study, understanding the risk for men and women treated with mycophenolate mofetil. And additional written consent from subject on the care and contraception agreement form for women of childbearing potential treated with mycophenolate.
-
Ability for subject to comply with the requirements of the study
-
Known diagnosis of significant respiratory disorders (asthma, tuberculosis, sarcoidosis, aspergillosis, or cystic fibrosis) other than CTD-NSIP, IPAF-NSIP and iNSIP
-
Evidence of any clinically significant, severe or unstable, acute or chronically progressive cardiac (severe heart failure New York Heart Association Class IV or severe uncontrolled cardiac disease), other medical disease (other than NSIP) or surgical disorder, or any condition that may affect patient safety in the judgment of the investigator.
-
HRCT pattern of typical usual interstitial pneumonia (UIP)
-
For patients with idiopathic ILD, HRCT pattern of possible UIP (no evocative of NSIP)
-
Histological pattern other than pattern of NSIP
-
A first line treatment with MMF or rituximab
-
Known hypersensitivity to MMF or rituximab or sulfonamide antibiotics

-
Patients with known hypoxanthine-guanine phosphoribosyl-transferase (HGPRT) hereditary deficiency (such as Lesch-Nyhan and Kelley-Seegmiller syndrome)
-
Pregnant or breastfeeding women, or women of child-bearing potential not using two reliable contraceptive methods (including female partners of sexually active men treated with mycophenolate) and men not using a contraceptive method (condom), or women and men having a pregnancy project during the year following randomization.

Group Intervention Description Placebo of rituximab with Mycophenolate Mofetil Placebo of Rituximab - Rituximab with Mycophenolate Mofetil Mycophenolate Mofetil - Rituximab with Mycophenolate Mofetil Rituximab - Placebo of rituximab with Mycophenolate Mofetil Mycophenolate Mofetil -
- Primary Outcome Measures
Name Time Method Change in FVC in % of predicted From baseline to 6 months Change in FVC (in % of predicted) since declines in FVC correlates with increased risk of subsequent mortality in ILD patients and FVC is one of the core set of outcomes defined in interstitial lung diseases. Data obtained from the two groups of patients (rituximab and placebo) will be compared to each other. FVC will be performed in each study center in a standardized manner according to the ATS/ERS recommendations and ECCS reference equations
- Secondary Outcome Measures
Name Time Method Changes in gammaglobulins Changes from baseline to 6 months in gammaglobulins Changes in gammaglobulins
Changes in HRCT of the chest images Changes from baseline to 6 months in HRCT of the chest images Changes in HRCT of the chest images
Adverse events related to treatment Adverse events during the 6 months of study period In particular infectious adverse events and biological blood disorders during the 6 months of study period will be collected
Rituximab PK parameters : distribution volume Points at Day1, Day15, 3 and 6 months Rituximab PK parameters : distribution volume
Rituximab clearance Points at Day1, Day15, 3 and 6 months Rituximab clearance
Half-life of rituximab in blood Points at Day1, Day15, 3 and 6 months Half-life of rituximab in blood
Progression Free Survival (PFS). PFS measured at 3, 6 and 12 months PFS is defined as the time 1) to the first acute exacerbation, or 2) to an absolute decline of 10 % points in the percentage of the predicted FVC, or 3) to the necessity to withdraw the MMF with/without a new immunosuppressive treatment (except corticoids), or 4) to death or 5) registration to a lung transplantation list. An acute exacerbation is defined by (1) progressive dyspnea over 1 month or less; (2) new pulmonary infiltrates on chest radiography or computed tomography, and (3) the absence of an overt underlying cause of rapid deterioration
Cough evaluation Changes from baseline to 6 months in cough evaluation Changes in cough evaluation
Changes in the quality of life score Changes from baseline to 6 months in the quality of life score, and, changes from baseline to 6 months in the visual analogic scales of dyspnea and cough The quality of life score as measured by the SF-36 v1.3 questionnaire, version developed and validated in interstitial lung disease (ILD) patients.
