JENA, Germany, Dec. 11, 2025 (GLOBE NEWSWIRE) -- InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company pioneering anti-inflammatory therapeutics by targeting the complement system, today announced that the World Health Organization (WHO) has granted the international nonproprietary (generic) name (INN) of "izicopan" to the Company for its orally available C5aR inhibitor, formerly known as INF904, in accordance with the WHO's Procedure for the Selection of Recommended International Nonproprietary Names (INN) for Pharmaceutical Substances. In the next step of this process, the name "izicopan" will be published in the recommended list of INNs.
Prof. Niels C. Riedemann, Chief Executive Officer and Founder of InflaRx, commented: "InflaRx welcomes the granting of izicopan as the INN for INF904. We believe the promising clinical data recently reported in hidradenitis suppurativa and chronic spontaneous urticaria indicate the tremendous potential izicopan has, as a best-in-class oral agent with a novel mechanism of action, to address significant unmet need in both diseases and also to address sizable commercial markets in additional inflammatory conditions."
About izicopan (INF904)
Izicopan (INF904) is an orally administered, small molecule inhibitor of the C5a receptor Ca5R1 that has shown anti-inflammatory therapeutic effects in several pre-clinical disease models and in human studies. Further, in contrast to the marketed C5aR inhibitor, in vitro experiments demonstrated that izicopan has minimal inhibition of the cytochrome P450 3A4/5 (CYP3A4/5) enzymes, which play an important role in the metabolism of a variety of metabolites and drugs, including glucocorticoids. Reported results from a first-in-human study demonstrated that izicopan was well tolerated 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 (ANs) and draining tunnels (dTs), 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 N.V.
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 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 is also developing izicopan (INF904), an orally administered small molecule inhibitor of C5a-induced signaling via the C5a receptor.
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. InflaRx GmbH (Germany) and InflaRx Pharmaceuticals Inc. (USA) are wholly owned subsidiaries of InflaRx N.V. (together, InflaRx).
