Trial summary

Drug serum concentrations will be measured at several time-points for inflammatory disease patients treated with anti-TNF agents. The purpose is to determine which patients that will clinically benefit from either discontinue treatment, adjusting the dose, switch to another anti-TNF agent or a different class of… Read more about this study

About this study

Drug serum concentrations will be measured at several time-points for inflammatory disease patients treated with anti-TNF agents. The purpose is to determine which patients that will clinically benefit from either discontinue treatment, adjusting the dose, switch to another anti-TNF agent or a different class of medication.

Read the detailed description

Crohn´s disease and ulcerative colitis are diseases where the proinflammatory cytokine Tumor Necrosis Factor-alpha (TNF) plays an important role. Anti-TNF agents are used in the treatment. However, some patients do not respond and response rates declines over time. The cause may be immunogenicity against the agent itself, the agent´s failure to neutralize TNF or another biological pathway leading to inflammation. Anti-TNF agents have been administrated as fixed doses at certain frequencies and this may not be optimal for all patients, but recent studies have indicated a correlation between efficacy and serum drug concentration levels (trough levels). Our preliminary data suggest that trough levels early in the treatment course may be predictive of later trough levels. By multiple measurements, this will be assessed. The study will also investigate biological markers in serum and blood cells which may be predictable for trough levels. Finally, we will compare different methods to measure serum drug concentrations.

What is being measured

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

  1. Measurement of drug serum concentrations

    Drug serum concentration will be measured using an ELISA

    Measured: Serum samples will be collected on average 8 weeks (range 0-90 days) after drug administration

Secondary outcomes (3)
  1. Measure soluble TNF-receptor in serum

    Measured: Measurement will be conducted in 2015 on blood samples stored in a bio-bank

  2. Assay validation

    Drug concentration measurements will be conducted with ELISA's with monoclonal and polyclonal antibodies, automated immunofluorometric assay and commercial kits for the purpose to validate tests and establish standards for measurements

    Measured: December 2013 - March 2014

  3. Change in individuals drug serum concentration

    Intra-individual fluctuations in consecutively measurements during a course of treatment will be measured.

    Measured: Serum samples will be collected on average 8 weeks (range 0-90 days) after drug administration

Questions about this trial

What is this clinical trial studying?

An observational study of Inflammatory Bowel Disease and Crohn's Disease, run by Oslo University Hospital at 1 site in Norway.

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 4 inclusion and 1 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 6 Dec 2016. 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 Norway. 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?

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?

Measurement of drug serum concentrations (time frame: Serum samples will be collected on average 8 weeks (range 0-90 days) after drug administration). 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 6 Dec 2016.
