Brief Summary
The purpose of this open-label, randomized, active-comparator-controlled study is to determine the efficacy and safety of frexalimab subcutaneous administrations up to 5 years compared to tacrolimus capsules in adults undergoing kidney transplantation. Participants aged 18 to 70 years who have low-to-moderate immunologic risk of graft rejection and receive their first kidney transplant are eligible if they meet all inclusion and no exclusion criteria. Study details include:
- The study and treatment duration will be up to approximately 5 years.
- The number of visits will be approximately 38.

Outcome Measures
Primary Outcomes (1)
Composite efficacy failure rate (BPAR, graft loss, and death) by 1 year post kidney transplantation
BPAR is defined as biopsy confirmed T cell mediated and antibody mediated rejection as categorized by BANFF 2022; graft loss is defined as the first date the patients meet any of the following criteria: chronic dialysis for a least 56 days, day of allograft nephrectomy, or day of re-transplant.
by 1 year
Secondary Outcomes (35)
eGFR at 1 year post kidney transplantation
at 1 year
eGFR at 6 months, 2 years, 3 years, 4 years, and 5 years post kidney transplantation
at 6 months, 2 years, 3 years, 4 years, and 5 years
Change of eGFR from Month 3 over time up to 5 years post kidney transplantation
from Month 3 over time up to 5 years
Participant status of eGFR > 60 mL/min/1.73 m2 at 1, 2, 3, and 5 years post kidney transplantation
at 1, 2, 3, and 5 years
Participant status of eGFR < 60 mL/min/1.73 m² at Month 12 or with a > 10 mL/min/1.73 m² decrease in eGFR from Month 3 to 12
from Month 3 to 12
- +30 more secondary outcomes

Eligibility Criteria
You may qualify if:
- Participants who are scheduled to receive their first kidney transplant from a living or deceased donor.
- Participants with low to moderate immunological risk.
You may not qualify if:
- Deceased donor kidney graft qualified as expanded criteria donor or donor after cardiac death.
- Positive T or B cell crossmatch, or positive virtual crossmatch per local practice at screening.
- Participants receiving a kidney graft from HLA-identical living-related donors, or have current or previous solid organ, cell, or multi-organ transplantation, or paired kidney transplantation.
- Participants whose primary causes of ESKD are idiopathic FSGS, C3 glomerulopathy, lupus nephritis, or thrombotic microangiopathy
- Evidence of active or latent TB, HIV, HBV or HCV infection.
- Participants who have known genetically predisposed thrombophilia, have history of thromboembolic events, or who need long-term anti-coagulation therapy.
- Participants who have severe medical co-morbidities, active infection, or severely limited life expectancy due to underlying medical conditions that are generally precluded from kidney transplant.
- The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
