Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Identification of a bacterial signature in the blood or stool that may be associated with acute rejection in patients treated with Nulojix during their first year of transplant.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Gut microbiota as well as the signature of the 16S plasma bacterial DNA and bacterial metabolites of patients on the date of transplantation and during the first year after transplantation will be analyzed. The phenotype of the patients' T lymphocytes will be analyzed at the same time. These data will be correlated with the occurrence of acute cell rejection during the first year of transplantation
