E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Long term treatment effects of a sirolimus based treatment compared to a ciclosporin based regimen shall be studied by comparing the randomized treatment groups of the former SMART-Study. The main question is whether different immunosuppressive regimens correlate with detection of donor specific antibodies in the follow up. |
Durch den Vergleich der beiden in der SMART-Studie randomisierten Patientengruppen nach Studienende sollen Langzeit-Effekte der Sirolimus-basierten Therapie im Vergleich zu einer Cyclosporin-haltigen Therapie untersucht werden. Insbesondere soll untersucht werden, inwieweit durch unterschiedliche, immunsuppressiv wirkende Medikamente (Sirolimus vs. Cyclosporin A) das Vorliegen von donor-spezifischen HLA-Antikörpern beeinflusst wird. |
|
E.2.2 | Secondary objectives of the trial |
Are there differences in the long term follow up between different immunosuppressive regimens after renal transplantation and is there a relationship between immunusuppressive therapy and detection of donor-specific antibodies on the one and the long term transplant function/survival on the other hand. |
Wie wird der Langzeitverlauf nach Nierentransplantation durch die unterschiedlichen immunsuppressiv wirkenden Medikamente (Sirolimus vs. Cyclosporin A) verändert? Möglicherweise lässt sich so ein Zusammenhang herstellen zwischen Konzentration / Vorliegen von donor-spezifischen Antikörpern und verabreichter Immunsuppression einerseits und dem klinischen Langzeitverlauf bzw. der Transplantatfunktion andererseits. Weiterhin sollen Erkenntnisse zum Auftreten neuer Begleiterkrankungen und von schwerwiegenden unerwünschten Ereignissen (SAE) gewonnen werden. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients who have participated in the former SMART Trial will be included, if the give written informed consent to participate in the present study. The main inclusion criteria into the SMART study were: - Male end female patients between 18 and 65 years of age who were scheduled to receive renal transplantation - first and second renal transplantation - PRA (panel reactive antibody titers) <= 30% |
Aufgenommen in die Studie werden alle Patienten, die in die SMART-Studie randomisiert worden waren und die ihr schriftliches Einverständnis erteilen, an dieser Studie teilzunehmen Die Haupt-Einschlus Kriterien in die SMART-Studie waren: - Männliche und weibliche Patienten im Alter zwischen 18 und 65 Jahren mit Indikation zur Nierentransplantation - Erste oder zweite Nierentransplantation - PRA <= 30% |
