E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy and safety of alefacept in a kidney transplant population. Data suggests that 12 weeks of treatment with alefacept in combination with tacrolimus, mycophenolate mofetil (MMF) and steroids may be more effective than and as safe as a combination therapy of tacrolimus with MMF and steroids. Effectiveness will be measured as the occurrence of and time to biopsy proven acute rejection at six months assessed locally. |
L'obiettivo primario di questo studio e' valutare l'efficacia e la sicurezza di alefacept in una popolazione trapiantata di rene. I dati in nostro possesso suggeriscono che 12 settimane di trattamento con alefacept in combinazione con tacrolimus, micofenolato mofetile (MMF) e steroidi possono essere piu' efficaci e ugualmente sicure della combinazione di tacrolimus con MMF e steroidi. L'attivita' sara' misurata nel verificarsi degli episodi di rigetto acuto, confermati istologicamente, e nel loro tempo di insorgenza durante i primi sei mesi dal trapianto, valutati localmente. |

E.3 | Principal inclusion criteria |
Subject is eligible for the study if all of the following apply: 1. Subject with end stage kidney disease who is a suitable candidate for primary kidney transplantation or re-transplantation. 2. Male or female subject at least 18 years of age and younger than 65 years. 3. Subject receiving a kidney transplant from a non-human leukocyte antigen (non-HLA) identical living donor or an HLA identical/non-HLA identical deceased donor between 5 and 59 years of age with compatible AB0 blood type. 4. Female subjects of childbearing potential must have a negative serum pregnancy test at enrollment and must agree to maintain effective birth control during the study. Effective birth control is defined as surgically sterilized, hormonal contraception or total abstinence at the discretion of the investigator in cases where age, career, lifestyle or sexual orientation ensures compliance of the subject. 5. Subject has been fully informed and has given written informed consent. Subject unable to write and/or read but who fully understands the oral information given by the investigator (or nominated representative) has given oral informed consent witnessed in writing by an independent person. |
I soggetti sono eligibili in questo studio se soddisfano tutti i seguenti criteri: 1. Soggetti con malattia renale in fase terminale candidati a trapianto renale primario o re-trapianto. 2. Soggetti di sesso maschile o femminile di eta' compresa tra 18 anni e 65 anni. 3. Soggetti che ricevono un trapianto di rene da donatore vivente non-HLA identico oppure da donatore cadavere HLA identico/non-HLA identico tra 5 e 59 anni di eta' e di gruppo sanguigno AB0 compatibile. 4. Soggetti di sesso femminile in eta' fertile con test sierologico di gravidanza negativo al momento dell'arruolamento e d'accordo a mantenere un efficace controllo delle nascite durante lo studio. Per efficace controllo delle nascite si intende sterilizzazione chirurgica, contraccezione ormonale o totale astinenza; si lascia alla discrezione dello sperimentatore la scelta del metodo che, relativamente all'eta', carriera, stile di vita e abitudini sessuali del soggetto assicuri la compliance del soggetto stesso. 5. Soggetti che siano stati dettagliatamente informati e abbiano dato il loro consenso informato scritto. Soggetti incapaci di scrivere e/o leggere, in grado pero' di comprendere appieno le informazioni verbali date loro dallo sperimentatore (o rappresentante delegato), che abbiano dato il loro consenso informato verbale testimoniato per iscritto da una persona indipendente. |

E.4 | Principal exclusion criteria |
Subject will be excluded from participation if any of the following apply: 1. Subject has a PRA grade > 20% in the previous 6 months and/or had had a previous graft survival shorter than 1 year due to immunological reasons. 2. Subject has received a kidney transplant from a non-heart beating donor. 3. Subject has received a kidney from a 50 - 59 year old donor with two of the following three factors: history of hypertension, cerebrovascular accident as cause of death, final pre-procurement serum creatinine >1.5 mg/dL (United Network for Organ Sharing UNOS expanded criteria donor). 4. Subject has previously received or is receiving an organ transplant other than kidney. 5. Cold ischemia time of the donor kidney is ≥ 30 hours. 6. Subject is pregnant or breastfeeding. 7. Subject has significant liver disease, defined as having continuously elevated AST and/or ALT levels greater than 2 times the upper value of the normal range. 8. Subject has known hypersensitivity to alefacept, tacrolimus, macrolide antibiotic, mycophenolate mofetil, corticosteroids or any of the product excipients. 9. Subject has received intravenous immunoglobulin (IVIG) therapy in the three months prior to first dose of study drug. 10. Subject requires initial sequential or parallel therapy with immunosuppressive antibody preparation. 11. Subject requires ongoing dosing with a systemic immunosuppressive drug at study entry for any reason other than kidney transplantation. 12. Subject or donor is known to be HIV positive. 13.

I soggetti saranno esclusi dalla partecipazione se si verifica uno dei seguenti criteri: 1.
