InflaRx to Present Late-Breaking Pre-clinical Data on Izicopan at Kidney Week 2026
InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company pioneering anti-inflammatory therapeutics by targeting the complement system, today announced that the Company has been selected for a late-breaking poster session at the American Society of Nephrology’s Kidney Week 2026, taking place in Denver, Colorado, USA, October 21 - 25.
Kidney Week 2026 Late-Breaking Poster Details
Title: Izicopan, a Second-Generation Oral C5a Receptor 1 (C5aR1) Antagonist, Demonstrates Promising Therapeutic Potential in Kidney Disease Models.
Poster Session Session Title: Late-Breaking Research Posters [LB-PO] Session Date, Time: October 22, 2026 from 10:00 AM to 12:00 PM
About izicopan Izicopan is an orally administered, small molecule inhibitor of the C5a receptor (C5aR) that has shown anti-inflammatory therapeutic effects in several pre-clinical disease models and in human studies. InflaRx is planning for development of izicopan in ANCA-associated vasculitis (AAV) and additional renal indications. In contrast to the marketed C5aR inhibitor, in vitro experiments demonstrated that izicopan does not exhibit time-dependent inhibition of cytochrome P450 3A4 (CYP3A4), which plays an important role in the metabolism of a variety of metabolites and drugs, including glucocorticoids. Izicopan has also demonstrated a favorable reactive metabolite profile in human liver microsomes. Reported results from a first-in-human study demonstrated that izicopan was well tolerated in treated subjects and exhibited no safety signals of concern in single doses ranging from 3 mg to 240 mg or multiple doses ranging from 30 mg once per day to 90 mg twice per day for 14 days. Pharmacokinetic / pharmacodynamic data support the best-in-class potential of izicopan, with a ≥90% blockade of C5a-induced neutrophil activation achieved over the 14-day dosing period. Topline Phase 2a data further support the safety profile of izicopan, with no reported safety signals of concern. In patients with hidradenitis suppurativa, over 4 weeks of therapy, izicopan provided rapid and clinically meaningful reductions in abscesses and nodules and draining tunnels, robust HiSCR responses that continued to deepen four weeks after the treatment period, and substantial reductions in patient-reported pain scores, overall demonstrating the potential for biologic-like efficacy. In chronic spontaneous urticaria, InflaRx observed substantial reductions in the 7-day Urticaria Activity Score (UAS7) broadly across patients and particularly in those with severe disease, as well as improved disease control as measured by the Urticaria Control Test (UCT7).
About InflaRx InflaRx (Nasdaq: IFRX) is a biopharmaceutical company pioneering anti-inflammatory therapeutics by applying its proprietary anti-C5a and anti-C5aR technologies to discover, develop and commercialize highly potent and specific inhibitors of the complement activation factor C5a and its receptor, C5aR. C5a is a powerful inflammatory mediator involved in the progression of a wide variety of inflammatory diseases. InflaRx‘s lead program is izicopan, an orally administered small molecule inhibitor of C5a-induced signaling via the C5a receptor, which has shown promising PK/PD characteristics as well as therapeutic potential in Phase 1 and Phase 2a clinical studies. The Company is developing izicopan for the treatment of ANCA-associated vasculitis and additional renal diseases. InflaRx also has developed vilobelimab, a novel, intravenously delivered, first-in-class, anti-C5a monoclonal antibody that selectively binds to free C5a and has demonstrated disease-modifying clinical activity and tolerability in multiple clinical studies.
InflaRx was founded in 2007, and the group has offices and subsidiaries in Jena and Munich, Germany, as well as Ann Arbor, MI, USA. For further information, please visit www.inflarx.de .
