E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
- To determine the starting dose of MIRCERA in pediatric patients with CKD on hemodialysis when switching from stable maintenance treatment with epoetin alfa, epoetin beta or darbepoetin alfa - To demonstrate changes in Hb over time in response to different iv doses of MIRCERA |
- Determinare la dose iniziale di MIRCERA in pazienti pediatrici con Malattia Renale Cronica in emodialisi precedentemente in terapia stabile di mantenimento con epoetina alfa, epoetina beta o darbepoetina alfa - Dimostrare i cambiamenti dei valori di Emoglobina (Hb) nel tempo in risposta a dosi e.v. diverse di MIRCERA |
|
E.2.2 | Secondary objectives of the trial |
- To study the pharmacokinetics (PK) of MIRCERA in pediatric patients - To explore MIRCERA exposure response relationship - To assess the safety and tolerability of multiple doses of MIRCERA in pediatric patients - To document long-term safety and efficacy of MIRCERA administration in pediatric patients with anemia associated with CKD |
- Studiare la farmacocinetica (PK) di MIRCERA in pazienti pediatrici- Esplorare la relazione esposizione-risposta a MIRCERA- Valutare la sicurezza e tollerabilita` di dosi multiple di MIRCERA in pazienti pediatrici- Documentare la sicurezza a lungo termine e l'efficacia della somministrazione di MIRCERA in pazienti pediatrici con anemia associata a Malattia Renale Cronica |
