Development of an anti-rat complement C2 antibody that improves renal outcome in a rat kidney transplant model
Year: 2026
Type: article
Abstract: Background: Previously we reported on the therapeutic monoclonal anti-human C2 antibody empasiprubart that inhibits activation of the classical and lectin pathways of complement. Preclinical studies with this antibody are hampered by its low affinity for C2 of animal species other than primates. Methods and results: -dependent anti-rat C2 antibody using the sequences and structural data of empasiprubart. Pharmacokinetics and pharmacodynamics of the resulting antibody in Sprague Dawley rats were assessed and used for an intervention study in a rat model of delayed graft function following kidney transplantation. The anti-rat C2 antibody improved kidney function and health in the rats within the first 2 weeks post-transplantation. Conclusion: disease models and highlights the potential of C2-blocking as a therapeutic strategy for preventing delayed graft function following kidney transplantation.
