Data from pre-clinical renal disease models demonstrate potential of izicopan for kidney protection Structural modeling provides new insight into izicopan’s differentiated molecular profile Jena, Germany, Oct. 22, 2026 (GLOBE NEWSWIRE) -- InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company pioneering anti-inflammatory therapeutics by targeting the complement system, today announced the presentation of new pre-clinical data on izicopan in renal disease models at the American Society of Nephrology’s Kidney Week 2026, taking place in Denver, Colorado, October 21 - 25. The in vivo and in vitro data demonstrated that izicopan robustly inhibited C5aR-mediated inflammatory responses and provided renal protection, supporting its potential as a therapeutic candidate for complement-driven kidney diseases. “The pre-clinical data presented at Kidney Week demonstrate the ability of izicopan to attenuate renal injury and provide a strong rationale for further development in renal diseases. Combined with its differentiated pharmacokinetic profile, including potentially reduced drug–drug interaction liability, faster onset of action, and more convenient dosing, we believe these results further support izicopan’s best-in-class potential,” said Renfeng Guo, MD, Chief Scientific Officer and Founder of InflaRx . “There is an important need for effective, safer treatment options for patients with complement-mediated inflammatory diseases, particularly in renal indications. We are excited to be advancing oral izicopan in ANCA-associated vasculitis as well as in additional kidney diseases.” Izicopan was evaluated in two established hamster models of kidney injury: renal ischemia–reperfusion injury (IRI), a model of acute kidney injury, and unilateral ureteral obstruction (UUO)-induced nephropathy, a model of progressive renal injury and fibrosis. In both settings, oral izicopan significantly attenuated renal injury compared to vehicle-treated controls. IRI model: A single oral dose of izicopan (100 mg/kg), administered four hours before surgery, significantly reduced plasma levels of the renal function markers creatinine and blood urea nitrogen (BUN) compared to vehicle (p < 0.001 for both). Izicopan also significantly improved the overall histopathological (H&E) score of the kidney, as well as the infarction and necrotic area scores (p < 0.05 for each). UUO model: Izicopan, administered orally five hours before surgery and then once daily for 14 days, significantly reduced BUN levels (p < 0.001) and significantly improved the total H&E histopathological score (p < 0.05) compared to vehicle. Izicopan also showed a numerical trend toward reduced kidney fibrosis (p = NS), as assessed by Masson’s trichrome staining, and α-smooth muscle actin (α-SMA)-positive cell counts. The structural modeling presented provides new insight into the differentiated molecular pro izicopan. Compared with avacopan, izicopan preserves the key structural features required for high-affinity C5aR1 binding, while its trifluoromethyl substituent reduces interaction with CYP3A4/5, providing a molecular rationale for its low potential for clinically relevant time-dependent inhibition (TDI).

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 (CYP3A4/5), 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 pro 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 pro 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).
