Desensitization in highly sensitized adult kidney transplant patients

8K US cases/yr · $128M Deal value €115M (~$128M USD) for EU/UK/EEA/MENA rights, Hansa Biopharma

Disease Overview

Highly sensitized kidney transplant candidates (cPRA >80-98%) have circulating anti-HLA IgG antibodies that cause positive crossmatch against most deceased donors, leading to multi-year waitlist times, higher mortality, and limited transplant access. Imlifidase cleaves IgG within hours to convert positive crossmatches to negative, enabling deceased-donor transplant in a population otherwise stranded on dialysis.

Competitive Landscape

Imlifidase is the only IgG-cleaving enzyme approved for kidney desensitization. Standard-of-care alternatives include IVIG, plasmapheresis, and rituximab-based regimens (off-label, days-to-weeks onset). Competitive threats include CSL's clazakizumab (IL-6 antibody, late-stage AMR program) and emerging FcRn blockers (efgartigimod, rozanolixizumab) being explored in transplant. SERB takes a focused critical-care/rare-disease franchise that fits its existing hospital specialty channel.
