Jena, Germany, Aug. 06, 2026 (GLOBE NEWSWIRE) --  InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company pioneering anti-inflammatory therapeutics by targeting the complement system, today announced financial results for the three months ended June 30, 2026, and provided a business update.

Prof. Niels C. Riedemann, Chief Executive Officer and Founder of InflaRx, said: “The second quarter was one of major momentum for InflaRx, as we focused on addressing the growing unmet need in ANCA-associated vasculitis, a rare but devastating inflammatory disease. As we track the evolving regulatory environment in AAV, we believe InflaRx is well positioned to bring the important C5a/C5aR inhibition mechanism forward to help patients. We are making substantial progress with Phase 2 planning for izicopan in AAV, while monitoring dynamic regulatory environments in the U.S. and overseas. Our focus remains on bringing novel and much-needed treatment options to patients in AAV and beyond, and we look forward to reporting additional progress in the coming months.”

Progress with izicopan, next-generation oral C5aR inhibitor,
and plans for further development

In May 2026, InflaRx announced it intends to develop izicopan in AAV, a rare, life-threatening autoimmune disease characterized by inflammation and damage to small blood vessels, with patients often experiencing renal impairment. Phase 2 planning for izicopan in AAV continues as planned.

The Company also announced it has targeted izicopan development in renal diseases, including atypical hemolytic uremic syndrome (aHUS), IgA nephropathy (IgAN) and C3 glomerulopathy (C3G), where early evidence exists for the role of C5a/C5aR inhibition and where izicopan’s favorable clinical profile could be a significant differentiator. InflaRx is currently in the planning stages for this development effort, with a goal of generating initial data from these open-label proof-of-concept studies in 2027.

Given the evolving regulatory environment surrounding the currently approved C5aR inhibitor, avacopan, InflaRx is evaluating the feasibility of multiple development approaches in AAV, including the potential for an expedited path to the commercial market in both the United States and Europe. Following the recommendation in June of the European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) to revoke the marketing authorization for Tavneos in the EU, InflaRx announced it intends to engage with EMA regarding vilobelimab and izicopan to evaluate the path to approval in AAV in Europe, with a goal of establishing the most efficient development plan to bring the C5a/C5aR inhibition mechanism to patients. Together, vilobelimab and izicopan provide InflaRx with a complementary biologic and oral pipeline that is well positioned to address the evolving treatment landscape and significant unmet medical need in AAV.

In April 2026, InflaRx announced new in vitro findings demonstrating that izicopan does not exhibit time-dependent inhibition of CYP3A4, an important indicator for the risk for drug-drug interactions (DDIs) and liver toxicity. Further, in May 2026, the Company announced new pre-clinical data demonstrating lower reactive metabolite formation of izicopan in human liver microsomes versus the marketed comparator, avacopan. Reactive metabolite formation is widely used in drug development as an early mechanistic indicator of potential bioactivation-related safety risk. While in vitro findings do not directly predict clinical outcomes, InflaRx believes these results support izicopan’s differentiated profile as a potentially best-in-class oral C5a receptor (C5aR) inhibitor.

Furthermore, with the goal of generating proof-of-concept data in additional I&I indications as efficiently as possible, InflaRx intends to initiate a PK bridging study with izicopan in China this year to expedite subsequent proof-of-concept studies in China and elsewhere.

$150 million underwritten offering of ordinary shares

In May, InflaRx announced the pricing of an underwritten registered direct offering of 75,000,000 ordinary shares at an offering price of $2.00 per share. The offering generated net proceeds of €119.3 million ($140.4 million), after deducting underwriting discounts and offering expenses. The Company intends to use the proceeds from the offering to advance its pipeline activities, including development in AAV and select renal diseases, and for working capital and general corporate purposes.

Capital Markets Day

The Capital Markets Day planned for October 8 (morning ET) will feature updates on InflaRx’s development strategy for AAV as well as the potential of izicopan as a best-in-class therapy offering differentiated chemistry, metabolic properties, and potential safety advantages. Details regarding the precise timing, the anticipated agenda and speaker line-up are expected by early September.

Dr. Thomas Taapken, Chief Financial Officer of InflaRx, said: “InflaRx is on sound financial footing with a reinforced balance sheet and strongly differentiated pipeline assets. With a sufficient cash runway projected through 2029, we are well positioned to achieve multiple clinical milestones, including initiation of clinical studies with izicopan in AAV and additional renal diseases, as well as their respective data readouts.”

Financial Highlights – 2Q 2026

Sales and marketing expenses

Sales and marketing expenses for the six months ended June 30, 2026, decreased by €2.3 million compared to the six months ended June 30, 2025, to €0.1 million. This decrease is attributable to the discontinuation of our sales activities at the end of 2025.

Research and development expenses

Research and development expenses for the six months ended June 30, 2026, decreased by €5.3 million to €8.9 million compared to the six months ended June 30, 2025, primarily due to lower third-party expenses for external services for the Group’s research and development projects, as well as lower personnel expenses due to reduced share-based payment expenses.

General and administrative expenses

General and administrative expenses decreased by €2.6 million to €5.7 million for the six months ended June 30, 2026, from €8.3 million for the six months ended June 30, 2025. This decrease is primarily due to lower personnel expenses, including reduced share-based payment expenses and lower legal and consulting fees.

Other income

Other income decreased by €1.0 million for the six months ended June 30, 2026, compared to the six months ended June 30, 2025, and primarily consists of research allowances under the “Forschungszulagengesetz” (Research Allowance Act) for the six months ended June 30, 2026.

Net financial result

For the six months ended June 30, 2026, our net financial result decreased by €5.2 million to a loss of €2.0 million from a gain of €3.2 million. This decrease is mainly attributable to fair value remeasurement effects of pre-funded warrants, issued in February 2025 in the amount of €14.1 million. This effect is partially offset by an €8.8 million improvement in the foreign exchange result.

Net loss

For the six months ended June 30, 2026, and 2025, the Company incurred net losses of €16.2 million or €0.17 per ordinary share and €22.7 million or €0.35 per ordinary share, respectively.

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. Further, 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). In addition, InflaRx is planning for development of izicopan in AAV and additional renal indications.

About vilobelimab

Vilobelimab 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, vilobelimab leaves the formation of the membrane attack complex (C5b-9) intact as an important defense mechanism of the innate immune system, which is not the case for molecules blocking C5. In pre-clinical studies, vilobelimab has been shown to control the inflammatory response-driven tissue and organ damage by specifically blocking C5a as a key “amplifier” of this response. Vilobelimab has been evaluated in two controlled Phase 2 AAV studies, the European IXCHANGE trial and the U.S. IXPLORE trial.

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‘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.
