InflaRx N.V. is focused on developing innovative therapeutics that target the C5a/C5aR signaling pathway within the complement system, which plays a crucial role in mediating inflammation. The company has made significant advancements in creating selective anti-C5a antibodies, such as vilobelimab, which is a first-in-class monoclonal antibody designed to inhibit the activity of C5a, a potent inflammatory mediator. By blocking C5a, InflaRx aims to mitigate the harmful effects of excessive inflammation associated with various acute and chronic inflammatory diseases, including ulcerative pyoderma gangrenosum and acute respiratory distress syndrome (ARDS). The therapeutic approach is particularly relevant in conditions where the immune response is dysregulated, leading to tissue damage and organ dysfunction.

In addition to vilobelimab, InflaRx is also developing INF904, an orally administered small molecule inhibitor targeting the C5a receptor (C5aR). This dual approach—utilizing both monoclonal antibodies and small molecule inhibitors—allows for a comprehensive strategy to modulate the inflammatory response. The company’s research indicates that inhibiting the C5a/C5aR pathway can lead to improved outcomes in various inflammatory conditions, as demonstrated in preclinical studies and ongoing clinical trials. By focusing on the complement system's role in inflammation, InflaRx is positioned to address significant unmet medical needs in the treatment of debilitating diseases.

Germany

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 product candidate, vilobelimab, is 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 in different indications. InflaRx is also developing INF904, an orally administered, small molecule inhibitor of 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.com

COVID-19

IFX-1 is a first-in-class monoclonal anti-human complement factor C5a antibody, which highly and effectively blocks the biological activity of C5a and demonstrates high selectivity towards its target in human blood. Thus, IFX-1 leaves the formation of the membrane attack complex (C5b-9) intact as an important defense mechanism, which is not the case for molecules blocking the cleavage of C5. IFX-1 has been demonstrated to control the inflammatory response driven tissue and organ damage by specifically blocking C5a as a key “amplifier” of this response in pre-clinical studies. IFX-1 is believed to be the first monoclonal anti-C5a antibody introduced into clinical development. Approximately 300 people have been treated with IFX-1 in clinical trials, and the antibody has been shown to be well tolerated. IFX-1 is currently being developed for various indications, including Hidradenitis Suppurativa, ANCA-associated vasculitis, Pyoderma Gangraenosum and COVID-19 pneumonia.

INF904 is an orally administered small molecule inhibitor of C5a-induced signaling via the receptor C5aR. INF904 showed anti-inflammatory therapeutic effects in several pre-clinical disease models. Further, in contrast to the marketed C5aR inhibitor, in vitro experiments demonstrated that INF904 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 INF904 is well tolerated in treated subjects and exhibits 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 (QD) to 90 mg twice per day (BID) for 14 days. Pharmacokinetic / pharmacodynamic data support best-in-class potential of INF904 with a ≥90% blockade of C5a-induced neutrophil activation achieved over the 14-day dosing period.
