E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We wish to ascertain the effectiveness of the two possible treatments for Aspergillus infection in CF (voriconazole and itraconazole) and compare these to each other. Effectiveness will be assessed by the effect on growth of Aspergillus in the sputum, which we will also confirm with more sensitive techniques based on detecting Aspergillus DNA. |
|
E.2.2 | Secondary objectives of the trial |
We are also interested in how quality of life and severity of CF symptoms respond to treatment of Aspergillus infection, how long the treatment needs to be given to be effective, what side effects patients experience (and how these differ between treatments) and how easy it is for CF patients to achieve effective drug levels. To do this we will measure the following outcomes: •Quality of life •Effect on lung function (forced expiratory volume in 1 second) •Use of additional antibiotics and steroids (often given to CF patients when unwell, so a valid measure of clinical status) •Drug absorption will be monitored by looking at levels of the antifungal agents in the blood. •Time to effect on sputum cultures of Aspergillus. •Effect of treatment on measures of allergic response to Aspergillus. •Side effect and safety profiles.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary evaluation criterion is the percentage of patients with a negativisation of sputum aspergillus cultures in 2 successive samples, according to a standardised technique.
We have given priority to the course and outcome of sputum aspergillus culture as the primary criterion because it is objective and indisputable. Given the confounding factors which can interfere in clinical criteria (progressive episode of the disease, viral or bacterial infectious complication, etc.)the latter will be analysed as secondary criteria. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
At 2 weeks after initiation of therapy : - measurement of plasma concentrations of antifungal agents and testing at 4 weeks in case of dose adjustment, - safety of AFs including measurement of hepatic transaminases, - number of courses of steroids and antibiotics and adverse events recording, At 4, 8, 16 and 24 weeks after initiation of therapy : - quality of life self-questionnaire scores (appendix 3), dyspnoea scale scores, 6 minute walking test, FEV1 value, and number of courses of steroids and antibiotics, - course of different laboratory test indicators (sputum culture and PCR, IgG, total and specific IgE, eosinophilia), - safety of the antifungal agents. At 1 month after the end of treatment : - clinical examination with a 6 minute walking test, FEV1 value, number of courses of steroids and antibiotics, and adverse events recording, - and a final sputum collection. After the end of treatment : - analysis of mycological failures (defined as persistence of a positive culture) by a study over time of the course and outcome of fungal biodiversity of isolates (sequential study of chemosensitivity to different antifungal agents and molecular typing). a study of the anti-inflammatory effect of azoles by measurement of serum and pulmonary pro-inflammatory cytokines (measurement of proinflammatory cytokines in the supernatants of the sputum (TNF-α, interleukin (IL)-8, IL-6, MMP1, MMP2, MMP9, EMMPRIN, MPO and free radicals) relating to the Group on Inflammation of the Federation of the CRC-CF (M. Fayon) and our research unit EA SeRAIC 4427 (University of Rennes 1). |
