InflaRx Showcases Vilobelimab’s Role in Immuno-Dermatology at the 2025 AAD Annual Meeting

Core Insights - InflaRx N.V. presented multiple data sets at the 2025 American Academy of Dermatology Annual Meeting, highlighting the potential of vilobelimab in treating inflammatory conditions such as pyoderma gangrenosum (PG) and hidradenitis suppurativa (HS) [1][2] Group 1: Vilobelimab in Pyoderma Gangrenosum (PG) - Safety data from a Phase 2a dose-finding study indicated that adverse events (AEs) were mostly mild to moderate, with vilobelimab being well tolerated across all doses [3] - Pharmacokinetic (PK) and pharmacodynamic (PD) analyses showed a significant reduction in C5a concentrations, with approximately 90% reduction observed by Day 15 across all dose groups [4] - The ongoing Phase 3 trial is utilizing vilobelimab dosed at 2400 mg bi-weekly to suppress C5a in ulcerative PG patients [4] Group 2: Vilobelimab in Hidradenitis Suppurativa (HS) - A post-hoc analysis from the Phase 2b SHINE trial demonstrated vilobelimab's effectiveness in reducing draining tunnels (dT) by 63.2% compared to 18.0% for placebo, with a 3.1x relative improvement in complete resolution of dT [5] - Safety analysis showed that vilobelimab was well tolerated, with similar rates and severity of AEs compared to placebo [6] - PK/PD analysis indicated that administration of 800 mg vilobelimab resulted in significant reductions in C5a concentrations, which remained lower than baseline during follow-up [7]
