- Male or female ≥ 18 years of age;
- Recipient of their first kidney transplant from a living or deceased donor;
- Willing and able to comply with the study requirements including prohibited concomitant medication restrictions;
- Agree not to participate in another interventional study while on treatment;
- If female, is surgically sterile or 2 years postmenopausal. Women of childbearing potential may be enrolled if a serum pregnancy test is negative at screening/baseline. Women of childbearing potential and men with partners that are of childbearing potential must agree to use highly effective methods of contraception from Screening, through 120 days after the last administration of the study drug. Examples of acceptable methods of contraception are described in Table 12.
You likely can't join if

What rules you out
- A patient who meets any of the following criteria will be excluded from this study: Induction therapy, other than study-assigned rATG, planned as part of initial immunosuppressive regimen;
- Known hypersensitivity to tegoprubart, tacrolimus, mycophenolate, rATG, corticosteroids, or any of their components;

- Currently treated with any systemic immunosuppressive regimen, including immunologic biologic therapies;
- Clinically significant abnormal ECG at Screening;
- Recipient is seronegative for EBV at Screening;
- Positive T- or B-cell crossmatch that is due to HLA antibodies or presence of a DSA at Screening;
- Thrombocytopenia (platelets < 75,000 per mm 3), leukopenia (white blood cells [WBC] < 3,000 per mm 3), or anemia (hemoglobin < 8 g/dL) at Screening;
- Desensitization therapy within 6 months of transplant;
- Pregnancy or breastfeeding;
- Unlikely to comply with the visits scheduled in the protocol, in the opinion of the Investigator;
- History of a TE event, known hypercoagulable state, or condition requiring long term anticoagulation or long-term antiplatelet medication
- Active coronavirus disease 2019 (COVID-19) infection at time of Screening or a recent history of COVID infection within 30 days prior to enrollment.
- Currently treated with corticosteroids other than topical or inhaled corticosteroids;
- Previous treatment with tegoprubart or any other anti-CD40L treatment.
- Previously received a bone marrow transplant or any other solid organ transplant, including a kidney, or will be undergoing a multi-organ or dual-kidney transplant;
- Will receive a kidney with an anticipated cold ischemia time of > 30 hours;
- Will receive a kidney from a donor that meets any of the following: Donation after Cardiac Death (DCD) criteria; Or Kidney Donor Profile Index (KDPI) of > 85%; Or Is blood group (ABO) incompatible;

- Recipient of an organ from an HLA identical living related donor.
- Recipient or donor is seropositive for human immunodeficiency virus (HIV), hepatitis B (HBV) surface antigen, or HBV core antibody or Hepatitis C (HCV). For HCV, a positive HCV antibody test is exclusionary unless the recipient is known to have been treated for HCV, in which case HCV RNA can be measured, and the recipient would only be excluded if HCV RNA positive;

Laboratory evidence of infection (positive PPD or QuantiFERON-TB Gold) in the absence of clinical infection is exclusionary unless the patient has completed treatment as recommended by local authorities; a. Participants with documented Bacillus CalmetteGuerin (BCG) vaccination and a negative chest x-ray may be included at the Investigator’s discretion;
