Brief Summary
The purpose of this study is to investigate the safety, tolerability, pharmacokinetics (PK) of FR104 as well as its potential clinical effect on acute rejection prophylaxis and renal function in a de novo renal transplant population receiving an allograft from standard criteria donors.

Outcome Measures
Primary Outcomes (1)
Safety of FR104 - Adverse Events with a focus on infectious complications. In particular
Type, severity (grades 3 and 4 adverse effects)., number and percent of Adverse Events with a focus on infectious complications. In particular, the following cumulative incidences will be calculated: Incidence of bacterial, fungal, viral, or parasitic infection, incidence of new malignancies, lymphopenia, anemia, leucopenia, cytopenia or biochemical disturbances related to the study drug.
Until Month 12
Secondary Outcomes (10)
Efficacy on Renal function
Month 6 and Month 12
Efficacy on Biopsy-proven acute rejection (BPAR)
Month 12
Efficacy on clinically-treated acute rejections
Month 12
Efficacy on steroid-resistant episodes
Month 12
Efficacy on multiples rejection episodes
Month 12
- +5 more secondary outcomes
