EXPLANATORY NOTE
On May 6, 2026, InflaRx N.V. (the “Company”) issued a press release titled “InflaRx Announces Advancement of Izicopan in ANCA-Associated Vasculitis and Select Renal Diseases.”
The Company today announced that it intends to develop izicopan, an oral C5a receptor (C5aR) inhibitor with potential best-in-class properties, in ANCA-associated vasculitis (AAV), a life-threatening kidney disorder. The Company is conducting Phase 2 planning for izicopan in AAV and is evaluating the feasibility of multiple development approaches, including the potential for an expedited path to the commercial market, in an effort to best address the evolving regulatory environment surrounding the currently approved comparator, avacopan.
In addition, the Company announced its goal of establishing rapid proof of concept for izicopan across a broader range of complement-mediated life-threatening kidney diseases by conducting open-label studies that are expected to begin generating clinical data next year in certain indications. These additional renal disease targets include atypical hemolytic uremic syndrome (aHUS), IgA nephropathy (IgAN) and C3 glomerulopathy (C3G), where early evidence already exists for the role of C5a/C5aR inhibition and where izicopan’s favorable clinical profile could be a significant differentiator. Toward these efforts, the Company anticipates conducting a pharmacokinetic bridging study in China this year.
A copy of the press release and a copy of the Company’s presentation are attached as Exhibit 99.1 and Exhibit 99.2, respectively. Both Exhibit 99.1 and 99.2 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act.
