PK - To define in silico the optimal dose for patients with CF aged 8 - 17 years. - To define the detailed pharmacokinetics in a limited number of children and adolescents with CF and Aspergillus infection aged 8-17 yrs through an intensive PK sampling study
Epidemiology, clinical efficacy and safety - To determine the prevalence of Aspergillus infection in children and adolescents aged 8 to 17 years. - To assess the safety and tolerability of posaconazole in children and adolescents with CF and Aspergillus infection. - To assess the clinical efficacy of posaconazole versus usual care in terms of (1) serological responses to Aspergillus; (2) airway inflammation, and (3) clinical outcomes (as measured by pulmonary exacerbation rate, days on antibiotics and corticosteroids, hospital admissions, quality of life, change in FEV1, change in BMI, CT- chest abnormalities) |

E.5 End points |
E.5.1 | Primary end point(s) |
- For the dosing algorithm: The number of children and adolescents with CF and Aspergillus infection aged 8 to 17 years reaching the pre-defined area under the concentration time curve (AUC) of posaconazole at the first assessment (between day 5 and 10) based on the adult reference concentrations for treatment of susceptible pathogens.
- For clinical efficacy: The number of children with negative sputum sample for Aspergillus infection at 3 months |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
- For the dosing algorithm between day 5 and 10 - For clinical efficacy: 3 months |
|
E.5.2 | Secondary end point(s) |
PK -The number of children and adolescents with CF and Aspergillus infection aged 8 to 17 years reaching the pre-defined area under the concentration time curve (AUC) of posaconazole at the second and third assessment (day 21-35, EOT) based on the adult reference concentrations for treatment of susceptible pathogens.
Epidemiology, clinical efficacy and safety - The proportion of children and adolescents aged 8 to 17 years with CF who screened positive for Aspergillus infection - The proportion of participants experiencing AEs and SAEs - Dose-response relationships between posaconazole exposure and toxicity - Forced expiratory volume (FEV1) at 3, 6 and 12 months post randomisation to evaluate if posaconazole is beneficial for CF-related Aspergillus infection. - Aspergillus in the airways (positive sputum culture) 3, 6 and 12 months post randomisation to evaluate if posaconazole is able to clear CF-related Aspergillus infection. - Levels of Aspergillus specific IgG and IgE 3, 6 and 12 months post randomisation to evaluate if posaconazole is able to normalize those levels. - Airway inflammation as measured by proteome profiling of sputum at baseline and 3 months post randomisation to evaluate if posaconazole is able to dampen inflammation in CF-related Aspergillus infection. - Clinical disease severity (as measured by pulmonary exacerbation rate, days on antibiotics and corticosteroids, hospital admissions, change in FEV1, change in BMI, CT-chest abnormalities) 3, 6 and 12 months post randomisation to evaluate if posaconazole has a beneficial effect. - Patient reported outcomes 3, 6 and 12 months post randomisation to evaluate if posaconazole has a beneficial effect (validated CFQR). |
