About this study

Official title: Comparative Analysis of Two Therapeutic Strategies: "Early Switch" Versus "Therapeutic Intensification" in Patients With Spondyloarthritis Treated With Anti-tnf Biologics, in Case of Secondary Treatment Failure Suspicion.

The objective of the study is to evaluate two therapeutic strategies: "early switch" or "therapeutic intensification" in patients with spondyloarthritis in case of secondary treatment failure suspicion to a first monoclonal antibodies anti-TNF definite by increase of ASDAS and positivity to ADAb.

Patients and Methods:

Read more

Multicentric randomized prospective study. Duration of inclusion 30 months. Duration of follow-up 24 months. 104 patients with spondyloarthritis treated with infliximab or adalimumab will be included if their ADAb dosage is positive, and they will be randomized (1:1) in two groups : "early switch" where treatment will be change to another anti-TNF, or "therapeutic intensification" where interval between two injections will be shortened. Patients will be evaluated clinically (ASDAS) and biologically (ADAb) at 12 weeks then at 24 weeks. Principal outcome will be the variation of ASDAS between baseline and end of the study. Number of patients to be included has been determined statistically from a preliminary study (power >98% for ASDAS variation of 20% on week 24).

Expected results:

On week 24, we expect a better response and a greater proportion of patients in remission in the "early switch" arm compare to the "therapeutic intensification" arm.

What is being measured

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

  1. Variation of ASDAS between inclusion and 24 weeks of treatment

    ASDAS will be measured at week 24 and will be compared to day 1

    Measured: Week 24

Secondary outcomes (1)
  1. Frequency of patients with ASDAS < 2.1

    Frequency of patients with ASDAS < 2.1 at week 24 ASDAS < 2.1 is considered as remission

    Measured: Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing anti drug antibodies dosage in people with Spondyloarthritis, run by University Hospital, Rouen at 7 sites 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 7 inclusion and 6 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: stopped early, as of the sponsor's last update on 15 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites 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 was stopped early (reason given: lack of recruitment). Results are not available in the source record.

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?

Variation of ASDAS between inclusion and 24 weeks of treatment (time frame: Week 24). 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 15 Jun 2017.
