Plain-language summary
The purpose of this study is to demonstrate the safety of tacrolimus extended-release in HLA sensitized (HS, defined as panel reactive antibody ≥ 30%), kidney transplant recipients after desensitization with intravenous immunoglobulin (IVIG) and rituximab (also known as ritux) +/- plasma exchange (PLEX) per the standard of care with alemtuzumab induction.

Inclusion criteria
✓. Recipient of a deceased or living donor kidney allograft
✓. Patients must have undergone desensitization with intravenous immunoglobulin (IVIG) and rituximab with or without plasma exchange prior to transplant or be administered IVIG and rituximab peri-operatively (within seven days of transplant) post-transplant
✓. Age 18 and over
✓. Able to understand and provide informed consent
✓. Calculated Panel Reactive Antibodies (CPRA)\> 30% demonstrated on 3 consecutive samples. The methodology to measure polymerase chain reaction (PCR) includes FLOW and Luminex Single Antigen Assay.
✓. At transplant, patient must have an acceptable crossmatch (as defined as T-or B- Flow Cytometry Crossmatch (FCMX) ≤ 225 MCS) from non-HLA identical donor. Negative crossmatch is Tpronase FCMX \<70; T- FCMX \<50 and Bpronase FCMX \<130; B-FCMX \<100.
Exclusion criteria
✕. Recipients of a dual simultaneous kidney/liver, kidney/heart, kidney/lung, or kidney/pancreas transplant
✕. History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes
✕. Patients being treated with drugs that are strong inducers or inhibitors of cytochrome P450 3A4
✕. Patients with a clinically significant systemic infection within 30 days prior to transplant
✕. Patients who have any surgical or medical condition that may affect absorption of drug, such as severe diarrhea, active peptic ulcer disease, or uncontrolled diabetes mellitus, which in the opinion of the investigator, might significantly alter the absorption, distribution, metabolism and/or excretion of study medication
