• All inclusion criteria must be met prior to randomization
• Males or females aged 18-65 years as of the date of informed consent who will undergo a single organ, living donor kidney transplant
• Donor aged 18-65 years as of the date of organ donation. A certain degree of HLA matching between the donor and the recipient is not required
• Blood type compatibility between recipient and donor must be established as follows; Recipient A to Donor A or O; Recipient B to Donor B or O; Recipient AB to Donor A, B, AB, or O; Recipient O to Donor O
• No prior organ transplant of any kind
• Women of childbearing potential must agree to use a medically acceptable method of contraception throughout the trial. A list of the medically acceptable methods of contraception are listed in the informed consent document
• Male patients must agree to use birth control following the initiation of standard-of-care immunosuppression and for a minimum of 6 months following kidney transplant
• Subjects (recipients) must be able to understand the consent form and give written informed consent prior to any trial procedure
• If donor informed consent is required by IRB/IEC, donor must be able to understand the consent form and give written informed consent prior to any trial procedure. Note: Donor informed consent is required for donors participating in the research assay collections

• The following exclusion criteria must be determined prior to randomization per SOC pre-transplant evaluation
• Known sensitivity or contraindication to thymoglobulin, everolimus, sirolimus, or tacrolimus or other immunosuppression medication prescribed
• Subjects with PRA >80% per SOC pre-transplant assessment. PRA must be repeated prior to transplant if patient receives a blood product transfusion after the initial assessment
• Subjects with current or historic donor specific antibodies
• Body Mass Index (BMI) of < 16 kg/m2 or > 38 kg/m2 per SOC pre-transplant evaluation
• Ongoing active drug or alcohol substance abuse, per judgement of an investigator
• Subjects with an active infection considered clinically significant by an investigator that has not resolved prior to transplant
• Subjects with an active infection considered clinically significant by an investigator that has not resolved prior to leukapheresis
• Subjects with PRA >80%, if repeated after SOC pre-transplant assessment. (PRA must be repeated prior to leukapheresis if patient receives a blood product transfusion after the initial assessment)
• Subjects who received an investigational drug within 30 days prior to leukapheresis
• Subjects who received anti-T cell therapy within 30 days prior to leukapheresis
• Subjects with an active infection considered clinically significant by the investigator that has not resolved prior to planned Treg infusion

• Subjects who received anti-T cell therapy within 30 days prior to infusion
• Subjects whose life expectancy is severely limited by diseases other than renal disease, per judgement of an investigator
• Major ongoing psychiatric illness or recent history of noncompliance with current medical therapy, per judgement of an investigator
• Malignancy within 3 years, excluding non-melanoma skin cancers such as basal cell carcinoma and squamous cell carcinoma
• Serologic evidence of active infection with HCV, HIV or HBV per SOC pre-transplant evaluation. Historical data within three months of transplant are acceptable
• Subjects with underlying renal disease etiologies with high risk of disease recurrence such as primary focal segmental glomerulosclerosis and others per investigator discretion
• Subjects requiring the use of chronic immunosuppressive medication to control an underlying renal disease, or a disease with extrarenal manifestations (i.e., inflammatory bowel disease). Subjects requiring chronic or intermittent use of inhaled corticosteroids for respiratory conditions will be allowed
• Subjects with a new, clinically significant medical condition that, per investigator opinion, would impact the ability to safely administer TRK-001
• Significant cardiovascular disease (e.g.):; Significant non-correctable coronary artery disease, per judgement of an investigator; Ejection fraction below 30% per SOC echocardiogram if an echocardiogram is performed for an individual subject as part of their pre-transplant evaluation; History of recent (< 12 months) myocardial infarction at time of informed consent; History of recent (within 3 months) vascular intervention(s) for coronary artery disease at the time of informed consent; Documented arrhythmias that require a pacemaker or medical therapy for control
• Subjects who require use of chronic anticoagulation medications. Use of anti-platelet medications will be allowed in absence of a documented arrhythmia
