Brief Summary
Some kidney transplant candidates have a very low chance of getting a kidney transplant because their immune systems are "highly sensitized" to most kidney donors. Being "highly sensitized" means that...
Detailed Description
This study will enroll 15 eligible adult participants with end stage renal failure on dialysis who are on the waiting list for a deceased donor transplant with calculated panel reactive antibodies (cP...

- Evidence of established immunity to Epstein-Barr Virus (EBV) as demonstrated by serologic testing
- Negative result of most recent tuberculosis (TB) testing or appropriately completed latent TB infection (LTBI) therapy.
- Testing should be conducted using either a PPD or interferon-gamma release assay (i.e., QuantiFERON-TB, T-SPOT.TB)
- Results from tests performed within 12 months prior to study entry are acceptable in the absence of any intervening exposure to TB

- Negative Hepatitis C antibody test at screening or as documented in medical record, up to 12 months prior to screening
- -If there is a history of treated hepatitis C then documentation of two consecutive negative HCV quantitative ribonucleic acid (RNA) Polymerase chain reaction (PCR) tests separated by at least 6 months is required. Untreated subjects with HCV RNA are eligible.
- Negative result for SARS-CoV-2 by an FDA-authorized molecular diagnostic test. Examples include, but are not limited to RT-PCR, LAMP, TMA, and qSTAR.
- Female subjects of reproductive potential must have a negative pregnancy test upon study entry
- All subjects of reproductive potential must agree to use of contraception for the duration of the study
- Subjects must have current vaccinations or documented immunity to varicella, measles, hepatitis B, pneumococcus, influenza, and zoster (if ≥50 years old)
- If subjects require administration of vaccines to meet eligibility requirements, they must wait at least 2 weeks between vaccination and the baseline (Visit 0) visit
Exclusion
- Individuals who meet any of these criteria are not eligible for enrollment as study subjects-

- Current treatment with other biological drug
- Immunization with live vaccine within 2 weeks of study baseline (Visit 0) visit
- Past or current medical problems or findings from physical examination or laboratory testing not listed above, which, in the opinion of the investigator, may:
