E.5 End points |
E.5.1 | Primary end point(s) |
Isovuconazole Penetration in Lung The concentrations of isavuconazole in plasma, epithelial lining fluid (ELF) and in alveolar macrophages (CA) will be determined by reverse phase HPLC (RP-HPLC). - Serum isavuconazole levels. Four determinations will be made per patient: 72 hours after the start of treatment, the day of bronchoscopy, simultaneously with the BAL and 7 days after the start of treatment. - Levels of isavuconazole in epithelial lining fluid (ELF) and in alveolar macrophages (CA), will be obtained from bronchoalveolar lavage (BAL). Data from the cell count, percentage of alveolar cells and volume of cell lining fluid will be presented at the different times when bronchoscopy is performed. The volume of cell lining fluid will be estimated using the concentration of urea in plasma and in LBA from the following formula: Estimated ELF volume = Amount of total UREA in LBA (mg) / plasma UREA concentration (mg / mL) The AUC of isavuconazole will be estimated at the ELF level and in CAs. The concentration-time-dependent curves in ELF and CA will be calculated using non-compartmental analyzes. The ratio between ELF / plasma and CA / plasma will be estimated from the average of the values of the patients included in each group. |
Penetración de isovuconazol en pulmón Se determinarán las concentraciones de isavuconazol en plasma, fluido de revestimiento epitelial (ELF) y en los macrófagos alveolares (CA) mediante HPLC en fase reversa (RP-HPLC). - Niveles isavuconazol en suero. Se realizarán 4 determinaciones por paciente: a las 72 h de iniciado el tratamiento, el día de la broncoscopia, simultáneamente a la realización del BAL y a los 7 días de iniciado el tratamiento. - Niveles de isavuconazol en fluido de revestimiento epitelial (ELF) y en los macrófagos alveolares (CA), se obtendrán a partir del lavado broncoalveolar (BAL). Se presentarán datos del recuento celular, porcentaje de células alveolares y volumen de líquido de revestimiento celular a los diferentes tiempos en que se realice la broncoscopia. El volumen de líquido de revestimiento celular se estimará utilizando la concentración de urea en plasma y en LBA a partir de la siguiente fórmula: Volumen estimado de ELF= Cantidad de UREA total en LBA (mg)/concentración de UREA en plasma (mg/mL) Se estimará el AUC de isavuconazol a nivel del ELF y en CAs. Mediante el uso de análisis no-compartimentales se calcularán las curvas concentración-tiempo dependiente en ELF y CA. Se estimará la razón entre ELF/plasma y CA/plasma a partir de la media de los valores de los pacientes incluidos en cada grupo. |

|
E.5.2 | Secondary end point(s) |
Interaction Evaluation: Tacrolimus and mycophenolate concentrations will be determined before and after 72 hours, 96 hours and 7 days after the start of treatment with isavuconazole. The percentage of patients who required dose adjustment of the immunosuppressive drug after the start of treatment with isavuconazole will be determined.
Systemic Security Assessment: According to the recommendations of the EMA (EMA / CPMP / EWP / 280/96 Corr1), systemic safety will be assessed according to the record of adverse effects, physical examination of patients, and the result of analytical studies |
Evaluación de la interacción: Se determinarán las concentraciones de tacrolimus y micofenolato antes y a las 72 horas, 96h y a los 7 días del inicio de tratamiento con isavuconazol. Se determinará el porcentaje de pacientes que precisaron ajuste de dosis del fármaco inmunosupresor tras el inicio de tratamiento con isavuconazol.
Evaluación de la seguridad sistémica: De acuerdo con las recomendaciones de la EMA (EMA/CPMP/EWP/280/96 Corr1), la seguridad sistémica se evaluará atendiendo al registro de los efectos adversos, a la exploración física de los pacientes, y al resultado de los estudios analíticos |
