The purpose of this study of obinutuzumab administered as intravenous (IV) infusion in adults with end stage renal disease is to assess the safety and tolerability of the regimen at week 24 of the desensitization phase and at week 28 post kidney transplantation. All participants will be monitored for a minimum of 12 months following the last obinutuzumab infusion.

Patients that need reconstruction or re-building of their urinary bladder are often limited to having a segment of their intestine used for that purpose. Using intestine is less than ideal as it is an absorptive, mucous producing tissue and placing this in constant contact with urine creates significant long term problems. In patients that require a kidney transplant and bladder reconstruction, this study seeks to use a bladder graft from a deceased donor rather than intestine.

Frailty is a condition characterized by slowness, weakness, low physical activity, wasting, and exhaustion. Frailty increases the risk for adverse outcomes following transplant such as increased length of stay in the hospital, mortality, or graft function. No interventions for frailty are known for patients with renal disease, but exercise programs like pulmonary rehabilitation have been effective in improving frailty in patients with other diseases, such as lung disease. The goal of this study is to test whether exercise will also improve frailty among patients who are waiting for a kidney transplant and who are considered frail or pre-frail.
