What this Trial Is About

Researchers are evaluating the effects of ALXN2030 in adult kidney transplant recipients who have active or chronic active antibody-mediated rejection (AMR). This phase 2, randomized, double-blind trial aims to compare ALXN2030 with a placebo to see how well it resolves AMR as confirmed by biopsy at Week 52. The study also assesses safety, how the drug moves through and acts in the body, and immune response to the drug. Participants will be randomly assigned to one of three groups: ALXN2030 Dose A, ALXN2030 Dose B, or placebo. All groups receive standard immunosuppressive therapy alongside study treatments. The treatments are given subcutaneously over a 52-week double-blind period. After this, those who received placebo will be re-randomized to receive ALXN2030 either at Dose A or Dose B during a 52-week open-label extension. Following treatment, participants enter a safety follow-up period lasting 48 weeks after the last dose. Throughout the study, participants will undergo kidney biopsies at Weeks 28 and 52 to evaluate the rejection status. Researchers will also monitor kidney function, drug levels in the blood, immune markers, and any adverse events from Day 1 up to Week 104. The total participation time includes treatment, extension, and follow-up phases, allowing comprehensive assessment of ALXN2030 effects and safety in kidney transplant patients with AMR.

  • Estimated glomerular filtration rate (eGFR) of at least 30 mL/min/1.73 m2
  • Vaccinated against meningococcal infection (serogroups A, C, W, Y, and B where available) between 14 days and 3 years before Day 1
  • Vaccinated against Streptococcus pneumoniae prior to randomization
  • Vaccinated against Haemophilus influenzae type B prior to randomization
  • Body weight of at least 50 kg at screening
Not Eligible

You will not qualify if you...

  • Diagnosis at screening of T-cell mediated rejection (Banff grade ≥ 1), polyoma virus nephropathy, severe thrombotic microangiopathy, or glomerulonephritis
