E.3 | Principal 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 to whom they are sensitized, and/or required desensitization prior to transplantation. 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 52 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 52 weeks after the last administration of IMP (BIVV020 + SOC arm participant) or last treatment period visit (SOC arm participant). - 18-75 years old at the time of consent. |
