What this trial studies

This clinical trial aims to assess the effectiveness and safety of rituximab in improving lung function in patients with progressive interstitial lung disease (ILD) that has an inflammatory component. Participants will receive either rituximab or a placebo in a double-blind manner, with the primary outcome measured at six months. The study focuses on patients who have experienced worsening ILD symptoms and have specific inflammatory markers in their lung tissue. By comparing the effects of the treatment against a placebo, the trial seeks to determine the potential benefits of rituximab for this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with worsening ILD symptoms and evidence of an inflammatory component in their lung condition.

Not a fit: Patients without an inflammatory component in their ILD or those who have not experienced recent worsening of their condition may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve lung function and quality of life for patients with progressive ILD.

How similar studies have performed: Other studies have explored the use of rituximab in various inflammatory conditions, showing promising results, but this specific application in ILD is relatively novel.

Eligibility criteria

Inclusion Criteria:

1. Patients ≥ 18 years old
2. Who meet at least one of the following criteria for worsening ILD within 24 months:

   1. a relative decline in the FVC of \>= 10% of the predicted value
   2. a relative decrease in the FVC of \>=5 to 10% of the predicted value AND i) worsening respiratory symptoms OR ii) an increased extent of ILD on high-resolution CT OR iii) a relative decrease in the DLCO of \>= 15% of the predicted value.
   3. worsening of respiratory symptoms AND an increased extent of ILD on high-resolution CT
3. AND presence of an inflammatory component defined by

   1. a previous histological pattern with lymphocyte infiltrations distant from pulmonary fibrosis to suggest an inflammatory component on pulmonary sample (for example: interstitial lymphoid aggregates with germinal centers, diffuse lympho-plasmocytic infiltrations, granulomas, giant cells or centrilobular inflammation…)

2. Concomitant medical or surgical disease, clinically significant as considered by the investigator, serious or unstable, acute or chronically progressive, or any condition that could affect the safety of the patient, in the opinion of the investigator including cardiomyopathy or heart failure.
3. Patient who can not walk more than 100 meters at 6-minutes walk test
