Arm Intervention/treatment
Experimental: FR104 Treatment Drug: FR104
FR104 treatment administration at day 0, day 14 then every 28 days until month 12




Primary Outcome Measures :
  1. Safety of FR104 - Adverse Events with a focus on infectious complications. In particular [ Time Frame: Until Month 12 ]
    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.


Secondary Outcome Measures :
  1. Efficacy on Renal function [ Time Frame: Month 6 and Month 12 ]
    Calculated glomerular filtration rate (CKD EPI) at each visit.

  2. Efficacy on Biopsy-proven acute rejection (BPAR) [ Time Frame: Month 12 ]
    Acute cellular rejection seen on renal biopsy for cause up to Month 12 (per Banff criteria 2017)

  3. Efficacy on clinically-treated acute rejections [ Time Frame: Month 12 ]
    Graft acute rejection up to Month 12. Number of AE related to treatment. Incidence and grade of rejection proven on Biopsy analysed after M12.

  4. Efficacy on steroid-resistant episodes [ Time Frame: Month 12 ]
    Steroid resistant episodes up to Month 12. Corticoresistant rejection up to month 12 defined as non response at day 5-6 after steroid boluses.

  5. Efficacy on multiples rejection episodes [ Time Frame: Month 12 ]
    Rejection episodes up to Month 12. Number of rejection after M12. According to histology. Incidence of biopsy-proven rejection (by banff grade).

  6. Efficacy on chronic allograft nephropathy [ Time Frame: Month 12 ]
    Chronic allograft nephropathy seen on renal biopsy for cause up to Month 12

  7. Efficacy on graft survival [ Time Frame: Month 12 ]
    Renal dialysis or new kidney transplant up to Month 12

  8. Treatment failure time [ Time Frame: Month 12 ]
    Time to treatment failure up to M12 (Biopsy-proven acute rejection, Graft Loss or Death)

  9. Evaluate the first Biopsy-proven acute rejection time [ Time Frame: Month 12 ]
    Time to the first Biopsy-proven acute rejection

  10. Evaluate the appearance of Donor specific Antibodies [ Time Frame: Month 12 ]
    Appearance of Donor specific Antibodies
