The BELASWITCH study is a prospective single-centre study including all kidney transplant patients for whom a conversion from Tacrolimus to Belatacept has been decided by the transplant clinicians of the Grenoble Alpes University Hospital.
Each patient will be included at the time of conversion (patients stable on Tacrolimus for at least 6 months) and will be their own control 1 year after conversion to Belatacept.
The study has two components:

The BELASWITCH study cohort is a prospective single-centre study including all adult kidney transplant recipients for whom a conversion from Tacrolimus to Belatacept has been decided by the transplant clinicians of the Grenoble Alpes University Hospital.
Each patient will be included at the time of conversion (patients stable on Tacrolimus for at least 6 months) and will be their own control 1 year after conversion to Belatacept.
