BIVV020 (SAR445088) in Prevention and Treatment of Antibody-mediated Rejection (AMR)

A Multi-cohort, Randomized, Phase 2, Open-label Study to Assess the Preliminary Efficacy, Safety, and Pharmacokinetics of BIVV020 for Prevention and Treatment of Antibody-mediated Rejection in Adult Kidney Transplant Recipients.

Primary Objectives:

• Cohort A: To evaluate the efficacy of BIVV020 in prevention of AMR
• Cohort B: To evaluate the efficacy of BIVV020 in treatment of active AMR

Secondary Objectives:

• To assess the overall efficacy of BIVV020 in prevention or treatment of AMR
• To characterize the safety and tolerability of BIVV020 in kidney transplant participants
• To characterize the pharmacokinetic (PK) profile of BIVV020 in kidney transplant participants
• To evaluate the immunogenicity of BIVV020

Up to approximately 2 years

Inclusion Criteria:

-Participant intended to receive SOC therapy per Investigator's judgment and local practice.

Cohort A: Participants with chronic kidney disease who will receive a kidney transplant from a living or deceased donor.

Cohort B: Participants who are kidney transplant recipients diagnosed with active AMR.

• BMI ≤ 40 kg/m2.
• Contraceptive use by women during the treatment period, and for at least 49 weeks after the last administration of IMP (BIVV020 + SOC arm participant) or last treatment period visit (SOC arm participant).
• Contraceptive use by men during the treatment period, and for at least 49 weeks after the last administration of IMP (BIVV020 + SOC arm participant) or last treatment period visit (SOC arm participant).

Exclusion Criteria:

• Participants who are ABO incompatible with their donors.

• Participants with known active ongoing infection as per below:

  1. Positive HIV.
  2. Positive HBV.
  3. HCV with detectable HCV RNA.
  4. Within 4 weeks of first study intervention: any serious infection, or any active bacterial infection, or any other infection which is clinically significant in the option of the Investigator, unless it can be confirmed that infection was cleared at least 3 days prior to first study intervention.

• History of active tuberculosis (TB) regardless of treatment.

• Participants with clinical diagnosis of systemic lupus erythematosus (SLE).

• Prior treatment with complement system inhibitor within 5 times the half-life.

• Current enrollment in any other clinical study where the last investigational study treatment administration was within 5 half-lives from study intervention initiation.
