Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • This inclusion will be definitive in V1, if :
  • The pre-inclusion criteria are respected,
  • The patient has not presented any exacerbation since V0 thereby define a basic state.
  • If patient could not be included, it will be possible to re-screen him for the study, provided he meets the pre-inclusion and inclusion criteria. In this case, a new V0 will be scheduled at least 3 months after the first V0.

Who cannot join

About this study

Official title: Interest of TARC Serum Marker for Follow-up of Patients With Allergic Broncho-Pulmonary Aspergillosis (ABPA), Excluding Cystic Fibrosis

The main objective of this study is to determine if a doubling of serum TARC (compared to baseline) is associated with the occurrence of exacerbations of ABPA.

The secondary objectives of the study are :

  1. To investigate if induced sputum eosinophils count (compared to baseline) is associated with the occurrence of exacerbations.
  2. To examine if the exhaled NO (compared to a baseline) is associated with the occurrence of exacerbations.
  3. To investigate if activation of circulating T cells (compared to a baseline) is associated with the occurrence of exacerbations.
  4. To examine if the rate of specific Asp f IgG measured by ELISA (compared to a baseline) is associated with the occurrence of exacerbations.
  5. To determine if the variation of one of the markers above, TARC or Asp f specific IgE measured at baseline, may be associated with the radiological stage of the disease (ABPA-S, ABPA-CB, ABPA-ORF).
  6. To investigate if there is a link between fungal exposure at home (visually assessed by the contamination level and the proportion of positive samples for Asp. f) and the frequency of exacerbations.
  7. To establish if some of the clinical, functional or biological data studied are associated with the frequency of exacerbations.

What participants receive

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

  • Study of predictive factorsOther

    Phase 1 : Inclusion of patients (V0) :

    In the case of a participation agreement, data on age, profession, previous history, history of the disease and current treatments will be collected. Different tests will be performed at this visit.

    Phase 2 : Determination of the baseline (V1) : Patients will be reviewed one month after V0 (V1). In the absence of exacerbation between V0 and V1, the examinations performed in routine practice will be used to determine the basic state of biological parameters of interest. During this visit, different tests will be performed.

    Phase 3 : Quarterly monitoring of patients (V2-V9) : Patients will be followed every three months for 2 years (V2-V9).

What is being measured

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

  1. The rate of serum TARC

    The rate of serum TARC will be measured by ELISA and expressed in pg / ml.Doubling of TARC rate compared between baseline (V1) and exacerbations is the primary endpoint (qualitative binary).

Secondary outcomes (9)
  1. Induced sputum eosinophils count

    Increase in induced sputum eosinophils count assessed by cytology between baseline visit (V1) and the visit(s) in exacerbation.

  2. The rate of Exhaled NO(FeNO50)

    Increase in exhaled NO (FeNO50) between baseline visit (V1) and the visit (s) in exacerbation.

  3. The rate of circulating T cells

    Increase in circulating T cells activation, measured by the rate of Th1, Th2, Th17, Treg lymphocytes by flow cytometry before and after specific Asp f. stimulation between baseline visit (V1) and the visit (s) in exacerbation.

  4. The rate of Aspf. specific serum IgG

    Increase of Aspf. specific serum IgG, measured by ELISA between baseline visit (V1) and the visit (s) in exacerbation

  5. Correlation between markers

    Correlation between previous markers, TARC or specific IgE measured at baseline and the stage of the radiological stage of the disease evaluated at V1 (ABPA-S, ABPA-CB, ABPA-ORF).

  6. Fungal exposure at home

    Link of fungal exposure at home with exacerbation frequency and the stage of disease severity.

  7. Clincal parameters

    Link between the clinical parameters (sex, complex aspergillosis, smoking, body mass index, reached ENT associated (chronic rhinitis, sinonasal-polyposis)) and the frequency of exacerbations.

  8. Biological parameters

    Link between the biological parameters measured at stable state (V1) (total IgE, Asp fspecific IgE, Aspergillus precipitins) and the frequency of exacerbations.

  9. Function parameters

    Link between the function parameters measured at baseline state (FEV1 (in%), FVC (in%), compared RV / TLC, FeNO50) and the frequency of exacerbations.

Questions about this trial

What is this clinical trial studying?

A study testing Study of predictive factors in people with Allergic Broncho-Pulmonary Aspergillosis, run by Nantes University Hospital at 2 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 4 inclusion and 10 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 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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.

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?

The rate of serum TARC. 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 Apr 2018.
