Trial summary

Rheumatoid arthritis (RA) is a common chronic systemic autoimmune relapsing disease characterized by joint inflammation. Beside arthritis leading to progressive joint damage and loss of function, RA is also associated to extraarticular inflammatory conditions such as interstitial lung disease (ILD).

About this study

Official title: Role of Lysophosphatidic Acid and Autotaxin in Rheumatoid Arthritis-associated Interstitial Lung Disease

Rheumatoid arthritis (RA) is a common chronic systemic autoimmune relapsing disease characterized by joint inflammation. Beside arthritis leading to progressive joint damage and loss of function, RA is also associated to extraarticular inflammatory conditions such as interstitial lung disease (ILD). This one develops in 30% of all RA patients with a median survival expectancy of 3 to 10 years once symptomatic. Unfortunately, there is no medical care recommendation so far as the pathophysiology is unknown. However, ILD share many similarities with idiopathic pulmonary fibrosis (IPF).

Autotaxin (ATX), due to its lysophospholipase activity, produces a bioactive lipid, lysophosphatidic acid (LPA) under inflammation. LPA has pleiotropic actions inducing cell proliferation, survival, motility and differentiation. Increased ATX and LPA levels have been detected in synovial fluid of RA patients and in IPF patients. ATX is also currently the target for a phase 3 clinical trial in IPF.

Given the previous described role of ATX/LPA axis in arthritis and inflammation-induced bone loss in RA and the similarities between RA-ILD and IPF, the investigators hypothesized that ATX/LPA axis may be also an attractive drug target for this pulmonary condition in RA and therefore that ATX and LPA may be increased in sputum from RA patients with ILD in comparison with sputum from RA patients without ILD.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Quantitative ATX and LPA determination in plasma and sputumOther

    Determination of ATX and LPA levels in plasma and sputum from RA-ILD patients ("cases") and in plasma and sputum from RA patients without ILD ("controls") after sputum induction using hypertonic saline inhalation

ControlsOtherPatients with RA and without ILD

Receives: Other: Quantitative ATX and LPA determination in plasma and sputum

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. ATX and LPA levels in sputum from RA patients with ILD in comparison with sputum from RA patients without ILD

    All the samples will be frozen and ATX and LPA levels will be assessed in the plasma and sputum at the same time, at the end of the recruitment.

    Measured: Month 30

Secondary outcomes (1)
  1. Correlation between ATX and LPA levels and severity of RA-ILD estimated by tomodensitometry

    Determine the correlation between ATX and LPA levels and the severity of CT scan pulmonary involvement*.

    *Diffuse interstitial lung disease is defined as an attack compatible with the thoracic scanner in thin sections according to international criteria with or without associated clinical signs.

    Measured: Month 24

Questions about this trial

What is this clinical trial studying?

A study testing Quantitative ATX and LPA determination in plasma and sputum in people with Rheumatoid Arthritis, run by Hospices Civils de Lyon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 27 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Fabienne COURY-LUCAS, MD (04 78 86 56 95 ext. +33, fabienne.coury@chu-lyon.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

ATX and LPA levels in sputum from RA patients with ILD in comparison with sputum from RA patients without ILD (time frame: Month 30). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jul 2021.
