Trial summary

Methotrexate (MTX) is the first-line treatment of rheumatoid arthritis (RA). In case of MTX failure, it is discussed to start a Biologic Disease-modifying Antirheumatic Drug (bDMARDs) according to the latest European recommendations of the EULAR. Read more about this study

About this study

Methotrexate (MTX) is the first-line treatment of rheumatoid arthritis (RA). In case of MTX failure, it is discussed to start a Biologic Disease-modifying Antirheumatic Drug (bDMARDs) according to the latest European recommendations of the EULAR. Before to add a Biologic Disease-modifying Antirheumatic Drug (bDMARDs), an objective estimation of MTX impregnation could be carried out by MTX polyglutamates (MTX-PG). In rheumatoid arthritis patients with active disease estimated by DAS28 (Disease activity Score 28)> 3.2 insufficiently controlled by MTX subcutaneously and patients in remission obtained with a DAS 28 <2.6 with methotrexate prescribed since more than 6 months at stable dose for at least 3 months, a concentration of MTX-PG will be achieved.

Read the detailed description

The assumption is the association between low methotrexate erythrocyte polyglutamate and low clinical response in rheumatoid arthritis patients treated with subcutaneous injectable methotrexate. Adherence to MTX will be assessed by the Compliance Questionnaire Rheumatology (CQR). Measurement of this adherence could optimize MTX treatment prior to the use of biotherapy which is costly with a lower infectious tolerance.

Correlation between its concentration and compliance assessed by CQR questionnaire will be tested.

What participants receive

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

  • Blood sampleBiological

    Blood samples will be collected for measuring PG-MTX blood concentration.

  • CRQDiagnostic test

    Also called Compliance Rheumatology Questionnaire

    Compliance Rheumatology Questionnaire (CQR) is a self-administered questionnaire for to evaluate therapeutic observance during rheumatoid arthritis.

What is being measured

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

  1. MTX-PG concentration

    To compare MTX-PG concentration in patients with active rheumatoid arthritis and patients with rheumatoid arthritis in remission

    Measured: Hour 1

Secondary outcomes (2)
  1. different metabolites dosing of MTX-PG

    Analysis of different metabolites dosing of MTX-PG by High-performance liquid chromatography technical

    Measured: Hour 1

  2. CQR score

    Analysis of CQR score response

    Measured: Hour 1

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Blood sample and CRQ in people with Rheumatoid Arthritis, run by Centre Hospitalier Universitaire de Saint Etienne 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 6 inclusion and 2 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: finished, as of the sponsor's last update on 3 Aug 2020. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

MTX-PG concentration (time frame: Hour 1). 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 3 Aug 2020.
