Budoprutug Phase 2 Mixed · 2026-10-26

Primary: Initial PrisMN Phase 2 data in primary membranous nephropathy (pMN): B-cell depletion, PLA2R antibody reduction and immunologic remission at Week 12 with budoprutug (anti-CD19 mAb) — At Week 12, the 200 mg cohort demonstrated B-cell depletion, reductions in PLA2R antibody levels, and immunologic remission, consistent with Phase 1b data (no numeric rates disclosed in the release text)

· Initial data from the ongoing 600 mg cohort suggest greater drug exposure and deeper peripheral B-cell depletion compared with 200 mg

· Enrollment is ongoing in the 1000 mg cohort; additional PrisMN data anticipated in 2027

· Separate minimal change disease case study: one patient achieved three-year steroid-free remission following budoprutug treatment

Safety: 200 mg and 600 mg doses have been generally well-tolerated (follow-up through Week 12 for 200 mg and Week 6 for 600 mg)
