- •Participants with LN only
- •Lymphocyte count below 0.5 × 109/L at screening.
- •Received any of Cyclophosphamide, Calcineurin inhibitors, IV methylprednisolone, IV immunoglobulin therapy, Belimumab, Obinutuzumab and Rituximab treatments at protocol specified time points.
- •Participants with C3G only
- •Evidence of monoclonal gammopathy of unclear significance, infections, malignancy, autoimmune diseases, or other conditions to which C3G is secondary.
- •Received systemic corticosteroid therapy, eculizumab, iptacopan, pegcetacoplan, or any other form of immunosuppressive therapy ≤12 weeks before Day 1, except for MMF (or mycophenolic acid), which is permitted.

Akebia Doses First Patient in Phase 2 Basket Trial of Ebribafusp for Rare Complement-Mediated Kidney Diseases- Akebia Therapeutics has dosed the first patient in an open-label Phase 2 basket trial of ebribafusp in IgA nephropathy, lupus nephritis and C3 glomerulopathy.
- The trial will enroll up to 30 patients who receive once-weekly subcutaneous ebribafusp for 26 weeks, followed by a long-term extension for responders.
- The primary endpoint is adverse event incidence, with secondary endpoints including proteinuria by UPCR, kidney function by eGFR and pharmacokinetics.
- Ebribafusp is an anti-C3d factor H fusion protein designed to inhibit complement activation in kidney tissue without suppressing complement in the blood, with initial data expected in 2027.2 days agoAkebia Doses First Patient in Phase 2 Basket Trial of Ebribafusp for Rare Complement-Mediated Kidney Diseases- Akebia Therapeutics has dosed the first patient in an open-label Phase 2 basket trial of ebribafusp in IgA nephropathy, lupus nephritis and C3 glomerulopathy.

• The company is prioritizing clinical trials for bempikibart in alopecia areata and a basket study of ADX-097 in autoimmune-related kidney damage.
• ADX-097, a complement-targeting antibody, aims to selectively inhibit the overactive complement system in affected tissues, based on promising Phase 1 results.
• The Phase 1 trial demonstrated ADX-097 was well-tolerated in healthy volunteers, with subcutaneous injections achieving sufficient drug levels to suppress complement activity.last year
