Vilobelimab in PG – Announcement on pivotal Phase 3 interim analysis expected at end of May to early June 2025

The interim analysis for the vilobelimab Phase 3 trial in pyoderma gangrenosum (PG), to determine trial size adaptation or futility, remains on schedule with the IDMC (independent data monitoring committee) recommendation expected to be announced by the Company at the end of May to early June, subject to minor variability in the timing of final IDMC-related workflows. This interim analysis (unblinded only for the IDMC) is planned for when 30 patients randomized 1:1 to the two arms have completed treatment. The analysis has a set of predefined rules and will consider the then-observed difference in complete target ulcer closure between the two arms and will determine whether the trial sample size should be adapted or whether the trial should be stopped due to futility. The study dosed its first patient in November 2023 and continues to enroll new patients. Total enrollment is projected to last at least two years, and the overall timing will depend on the total trial size after sample size adaptation.

Vilobelimab has been granted orphan drug designation for the treatment of PG by both the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), as well as fast track designation by the FDA.

INF904 in CSU and HS – Topline Phase 2a data expected in summer 2025

InflaRx is conducting a Phase 2a basket study with INF904 in CSU and HS, with topline data expected in the summer of 2025. This is a multi-center, open-label study evaluating multiple INF904 dosing regimens over 4 weeks of treatment in a total of 75 patients (45 with CSU and 30 with HS). The goal of the trial is to generate safety and pharmacokinetic (PK) data and to provide signs of clinical benefit, with an objective of informing the planning and design of a larger, longer-term Phase 2b study by year-end 2025.

The Company also successfully completed the required sub-chronic and chronic toxicology studies for INF904. No safety signals of concern were identified, supporting the potential for long-term dosing in future clinical efforts. Additional required non-clinical studies remain ongoing as planned.

InflaRx believes CSU and HS each have potential addressable markets of $1 billion or more for INF904. The Company also believes INF904 could address meaningful opportunities in additional immuno-dermatology and immuno-inflammatory indications, including in nephrology, neurology and hematology. While InflaRx intends to focus its resources on its immediate goals addressing CSU and HS, the Company continues to assess and monitor the value of pursuing additional areas and applications via potential future collaborations with partners.

GOHIBIC (vilobelimab) granted EU marketing authorization

In January 2025, the European Commission (EC) granted marketing authorization under exceptional circumstances for GOHIBIC (vilobelimab) for the treatment of adult patients with SARS-CoV-2-induced acute respiratory distress syndrome (ARDS) who are receiving systemic corticosteroids as part of standard of care and receiving invasive mechanical ventilation (IMV) with or without extracorporeal membrane oxygenation (ECMO). GOHIBIC (vilobelimab) is the first and only treatment approved in the European Union (EU) for the treatment of SARS-CoV-2-induced ARDS. InflaRx is considering commercial partnering and distribution options in the EU and does not expect this approach will have a materially negative impact on its cash burn rate.

Dr. Thomas Taapken, Chief Financial Officer of InflaRx, said :“InflaRx's balance sheet is strong as the Company enters a period of multiple expected catalysts and potential value inflection points over the remainder of 2025 and beyond. With our solid financial position, we are able to invest in our key development programs while maintaining a cash runway into 2027.”

Financial highlights – Q1 2025

Financing activities

In February 2025, the Company completed an underwritten public offering of ordinary shares and pre-funded warrants, raising gross proceeds of €28.7 million ($30.0 million), before deducting the underwriting discount and offering expenses.

Revenue

For the three months ended March 31, 2025, we realized no revenues from the product sales of GOHIBIC (vilobelimab). Compared to the three months ended March 31, 2024, this is a decrease of €36 thousand. Sales to distributors do not constitute revenue for the Company. All revenues are attributed to sales made in the United States.

Cost of sales

Cost of sales during the three months ended March 31, 2025 amounted to €9.3 thousand due to inventory write-offs in connection with the replacement of product with an expiring shelf-life. This represents a decrease of €0.2 million compared to the three months ended March 31, 2024.

Sales and marketing expenses

Sales and marketing expenses incurred for the three months ended March 31, 2025 amounted to €1.5 million and were nearly unchanged compared to the three months ended March 31, 2024.

Research and development expenses

Research and development expenses for the three months ended March 31, 2025 decreased by €0.3 million to €7.0 million, compared to the three months ended March 31, 2024. This decrease is primarily due to lower third-party expenses incurred in connection with the Company's efforts to develop INF904.

General and administrative expenses

General and administrative expenses for the three months ended March 31, 2025 increased by €1.5 million compared to the three months ended March 31, 2024, mainly due to higher legal, consulting and audit expenses of €0.4 million and higher other expenses in the amount of €0.5 million, mainly in conjunction with the issuance of pre-funded warrants in our recently conducted public offering and higher personnel expenses due to share based payments.

Other income

Other income for the three months ended March 31, 2025 amounted to €0.5 million, compared to €36 thousand for the three months ended March 31, 2024. Other income was primarily due to income from research allowances.

Net financial result

Net financial result increased by €1.9 million to a gain of €4.7 million for the three months ended March 31, 2025 from a gain of €2.8 million for the three months ended March 31, 2024. This increase is mainly attributable to the fair value revaluation of pre-funded warrants issued in February 2025 in the amount of €6.1 million, as well as to a decrease of the foreign exchange result by €3.7 million due to the weakening of the U.S. dollar and a decrease of interest income on marketable securities (due to lower investments in 2025) by €0.4 million, in each case, compared to the three months ended March 31, 2024.

Net loss

We incurred a net loss of €8.3 million, or €0.13 per ordinary share, in the first quarter of 2025, compared to €9.7 million, or €0.17 per ordinary share, in 2024.

Liquidity and capital resources

As of March 31, 2025, our total funds available amounted to approximately €65.7 million, comprised of €47.3 million of cash and cash equivalents and €18.4 million of marketable securities.

Net cash used in operating activities

Net cash used in operating activities decreased to €14.0 million in the three months ended March 31, 2025, from €14.9 million in the three months ended March 31, 2024.

Net cash from financing activities

Net cash from financing activities increased by €27.1 million in the three months ended March 31, 2025, to €27.0 million, compared to the three months ended March 31, 2024, due to a public offering of ordinary shares and pre-funded warrants in February 2025.

About GOHIBIC (vilobelimab)

In the EU, GOHIBIC (vilobelimab) has been granted marketing authorization under exceptional circumstances for the treatment of adult patients with SARS-CoV-2-induced ARDS who are receiving systemic corticosteroids as part of standard of care and receiving IMV (with or without ECMO). The EU approval of GOHIBIC (vilobelimab) is supported by the previously announced results of the multicenter Phase 3 PANAMO trial, one of the largest 1:1 randomized, double-blind, placebo-controlled trials in invasively mechanically ventilated COVID-19 patients in intensive care units. The results showed that vilobelimab treatment improved survival with a relative reduction in 28-day all-cause mortality of 23.9% compared to placebo in the global data set. The data was published in The Lancet Respiratory Medicine.

A marketing authorization under exceptional circumstances is recommended when the benefit/risk assessment is determined to be positive but, due to the rarity of the disease, it's unlikely that comprehensive data can be obtained under normal conditions of use. Under the terms of GOHIBIC (vilobelimab)'s approval in the EC, InflaRx will provide annual updates to EMA on the previously announced clinical platform study planned by the Biomedical Advanced Research and Development Authority (BARDA). Vilobelimab is included in this study as one of three new potential therapies for treating ARDS.

In the U.S., GOHIBIC (vilobelimab) has been granted an Emergency Use Authorization by the FDA for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO. The emergency use of GOHIBIC (vilobelimab) is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated, or authorization revoked sooner.

GOHIBIC (vilobelimab) is an investigational drug that has not been approved by the FDA for any indication, including for the treatment of COVID-19. There is limited information known about the safety and effectiveness of using GOHIBIC (vilobelimab) to treat people in the hospital with COVID-19. Please see additional information in the Fact Sheet for Healthcare Providers, Fact Sheet for Patients and Parents/Caregivers and FDA Letter of Authorization on the GOHIBIC (vilobelimab) website .

Important Safety Information about GOHIBIC (vilobelimab)

There is limited clinical data available for GOHIBIC (vilobelimab). Serious and unexpected adverse events (AEs) may occur that have not been previously reported with GOHIBIC (vilobelimab) use.

GOHIBIC (vilobelimab) has been associated with an increase of serious infections. In patients with COVID-19, monitor for signs and symptoms of new infections during and after treatment with GOHIBIC (vilobelimab). Hypersensitivity reactions have been observed with GOHIBIC (vilobelimab). If a severe hypersensitivity reaction occurs, administration of GOHIBIC (vilobelimab) should be discontinued and appropriate therapy initiated.

The most common adverse reactions (incidence ≥3%) are pneumonia, sepsis, delirium, pulmonary embolism, hypertension, pneumothorax, deep vein thrombosis, herpes simplex, enterococcal infection, bronchopulmonary aspergillosis, hepatic enzyme increased, urinary tract infection, hypoxia, thrombocytopenia, pneumomediastinum, respiratory tract infection, supraventricular tachycardia, constipation, and rash.

Healthcare providers and/or their designee are responsible for mandatory FDA MedWatch reporting of all medication errors and serious AEs or deaths that occur during GOHIBIC (vilobelimab) treatment and are considered to be potentially attributable to GOHIBIC (vilobelimab).

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 is being developed for various debilitating or life-threatening inflammatory indications, including PG. Vilobelimab has been granted orphan drug designation for the treatment of PG by both the FDA and the EMA, as well as fast track designation by the FDA.

About INF904

INF904 is an orally administered, small molecule inhibitor of the C5a receptor that has shown 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. PK / pharmacodynamic data support the best-in-class potential of INF904 with a ≥90% blockade of C5a-induced neutrophil activation achieved over the 14-day dosing period.

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 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 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 .
