InflaRx Reports Full Year 2024 Results and Highlights Key Achievements and Expected Milestones

Insights

Biotech Financial Analyst

InflaRx's year-end results reveal a strategic advancement phase with significant regulatory success and pipeline progression, despite widening losses. The EU approval for GOHIBIC (vilobelimab) represents their first marketed product in Europe for SARS-CoV-2-induced ARDS, creating potential future revenue streams, though commercialization partnerships would be needed to realize this potential.

The company's financial position shows strengthening, with €55.2 million in cash at year-end, bolstered by an additional €28.7 million raised in February 2025. This extends their runway into 2027, providing critical operational stability through multiple clinical readouts. However, the €46.1 million net loss (versus €42.7 million in 2023) highlights ongoing cash burn challenges typical for clinical-stage biotechs.

Two key catalysts warrant investor attention: the upcoming interim analysis for the Phase 3 vilobelimab PG trial expected by May 2025, and summer 2025 topline data from the Phase 2a trial of oral C5aR inhibitor INF904 in CSU and HS. Both represent potential inflection points, particularly as the company estimates these indications could each represent addressable markets exceeding $1 billion.

R&D expense reduction to €35.4 million (down €5.7 million) demonstrates improved operational efficiency, though increased marketing expenses of €2.8 million and inventory write-downs of €2.8 million partially offset these gains. Current product revenue remains minimal at just €0.2 million, emphasizing that InflaRx remains primarily a development-stage company despite having approved products.

Pharmaceutical Development Specialist

InflaRx's complement pathway inhibitor portfolio shows promising clinical development momentum. The European Commission approval for GOHIBIC (vilobelimab) marks a significant regulatory achievement as the first approved treatment for SARS-CoV-2-induced ARDS in the EU. This validates their C5a inhibition approach while creating a template for potential future approvals.

Their pyoderma gangrenosum (PG) program has reached a critical juncture with the 30-patient recruitment milestone enabling an interim analysis by May 2025. This adaptive trial design is strategically sound for a rare disease indication, allowing for sample size adjustments based on observed treatment effects, potentially accelerating development timelines while controlling costs.

The oral C5aR inhibitor INF904 represents InflaRx's next-generation approach, with potential advantages in dosing convenience and possibly differentiated efficacy. The Phase 2a basket trial design in CSU and HS is efficient, examining both safety/PK and preliminary efficacy signals simultaneously across multiple indications. The 4-week treatment period should provide sufficient data to inform future development, though longer treatment duration would be needed to fully assess chronic treatment potential.

Multiple AAD presentations highlighting vilobelimab's potential in reducing systemic inflammation reinforce the broader applicability of their complement inhibition platform. The selection by BARDA for inclusion in their ARDS platform study provides additional validation and potential for expanded indications beyond COVID-19, supporting the company's scientific approach and potentially broadening future market opportunities.

JENA, Germany, March 20, 2025 (GLOBE NEWSWIRE) -- InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company pioneering anti-inflammatory therapeutics by targeting the complement system, today announced its financial results for the year ended December 31, 2024, highlighting recent operational achievements and expected milestones for 2025.

Prof. Niels C. Riedemann, Chief Executive Officer and Founder of InflaRx, commented: “2024 was a highly productive year for InflaRx, with the company achieving all major development and regulatory goals across its pipeline programs and making meaningful progress in addressing critical medical needs in inflammatory diseases.” He continued: “We look forward to a catalyst-rich year in 2025 as we continue to advance our pipeline, including reaching the interim analysis for the Phase 3 trial with vilobelimab in pyoderma gangrenosum and reporting top-line Phase 2a data in chronic spontaneous urticaria and hidradenitis suppurativa with INF904, our oral C5aR inhibitor with best-in-class potential."

Select recent highlights and expected milestones

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

In December 2024, InflaRx announced that the first patient had been dosed in its Phase 2a basket study with INF904 in CSU and HS. 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 in CSU and 30 in HS). The goal of the trial is to generate additional safety and pharmacokinetic (PK) data and to provide signs of clinical benefit. After the 4-week treatment period, patients will be followed for an additional 4 weeks. Topline data from this study are expected in the summer of 2025, with a goal of informing the planning and design of a larger, longer-term Phase 2b study by year-end 2025.

InflaRx believes CSU and HS each has 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.

Vilobelimab in PG – Pivotal Phase 3 trial interim analysis expected by the end of May 2025

In November 2024, InflaRx announced that it had achieved the 30-patient recruitment milestone in its ongoing Phase 3 vilobelimab trial in PG. This is expected to enable the interim analysis for trial size adaptation or futility by the end of May 2025. Trial enrollment continues. The study dosed its first patient in November 2023 and has an adaptive design with an interim analysis (unblinded only for the independent data monitoring committee), which is planned when 30 patients randomized 1:1 to the two arms have completed treatment. The interim analysis with a set of predefined rules will consider the then-observed difference in complete target ulcer closure between the two arms and will then determine whether the trial sample size will be adapted or whether the trial should be stopped due to futility. The enrollment period is projected to last at least two years, and its overall period will depend on the total trial size after sample size adaptation.

The Phase 3 trial is a multi-national, randomized, double-blind, placebo-controlled pivotal study assessing the benefit of vilobelimab for treating ulcerative PG, a rare, chronic inflammatory form of neutrophilic dermatosis characterized by accumulation of neutrophils in the affected skin areas. The trial has two arms: (1) vilobelimab plus a low dose of corticosteroids and (2) placebo plus the same dose of corticosteroids, both tapered over an 8-week period. The primary endpoint of the study is complete closure of the target ulcer measured at two consecutive visits at any time up to 26 weeks after initiation of treatment.

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.

Vilobelimab presentations at the 2025 AAD Annual Meeting

During the 2025 American Academy of Dermatology (AAD) Annual Meeting held March 7 – 11 in Orlando, FL, vilobelimab was featured in multiple sessions. Collectively, these data highlighted the utility of vilobelimab in treating multiple inflammatory conditions, including PG and HS, with supporting evidence from clinical efficacy data, safety assessments, and pharmacokinetic and pharmacodynamic analyses.

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 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.

The marketing authorization under exceptional circumstances for GOHIBIC (vilobelimab) is valid in all 27 EU member states as well as Iceland, Liechtenstein, and Norway. 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.

In June 2024, InflaRx announced that GOHIBIC (vilobelimab) had been selected by the Biomedical Advanced Research and Development Authority (BARDA), part of the Administration for Strategic Preparedness and Response within the U.S. Department of Health and Human Services, as one of three investigational therapies to be assessed in a Phase 2 clinical platform study exploring potential new options for the treatment of ARDS. Vilobelimab is one of three host-directed investigational drugs assessed in this study, with the safety and efficacy of each investigational drug to be studied in its own patient cohort and compared against placebo. This Phase 2 platform study is expected to collect data in order to define subsets of patients with ARDS who may benefit from specific host-directed therapeutics and to inform the design of potential Phase 3 studies.

Dr. Thomas Taapken, Chief Financial Officer of InflaRx, said: “With our recent successful capital raise and the efficient utilization of our balance sheet, InflaRx is on solid financial footing, enabling us to efficiently advance our key development programs. Importantly, our cash runway into 2027 should allow us to reach several value inflection points, including the end-of-May interim analysis for the vilobelimab Phase 3 study in pyoderma gangrenosum, along with the eventual readout of this trial, as well as the INF904 Phase 2a topline data this summer.”

Financing activities

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

2024 Financial highlights
Revenue

In 2024, we realized revenues from product sales of GOHIBIC (vilobelimab) in the amount of €0.2 million, which represents an increase of €0.1 million compared to the prior year. Revenues reported are sales to end customers (hospitals). 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 increased by €2.8 million in 2024 compared to the corresponding costs for 2023, primarily due to higher inventory write-downs of €2.8 million as a result of quantities on hand exceeding quantities expected to be sold prior to expiry.

Marketing and sales expenses

Marketing and sales expenses increased by €2.8 million in 2024 compared to 2023, as 2024 represented the first full year of commercial efforts for GOHIBIC (vilobelimab) in the United States. In 2023, marketing and sales expenses were only incurred during the second half of the year.

Research and development expenses

Research and development expenses decreased by €5.7 million to €35.4 million in 2024 compared to the year 2023. This decrease was primarily attributable to €8.7 million lower third-party costs from manufacturing development activities and from clinical trials, offset by €1.6 million higher personnel expenses and €1.4 million higher other expenses compared to the previous year. Other expenses include a one-off milestone contractual payment of $1.0 million (€1.0 million) relating to market authorization for GOHIBIC (vilobelimab) in the EU.

General and administrative expenses

General and administrative expenses increased by €0.4 million to €13.0 million for the year ended December 31, 2024, from €12.6 million for the year ended December 31, 2023. This increase is comprised of higher personnel expenses of €0.9 million and partially offset by a decrease in legal and consulting expenses of €0.4 million and a decrease in insurance expenses of €0.4 million.

Other income

Other income decreased by €7.9 million in 2024 compared to the year 2023 due primarily to lower income from government grants. In June 2023, our grant from the German Ministry of Education and Research and the German Ministry of Health to support the development of vilobelimab for the treatment of severe COVID-19 patients ended. In 2024, upon qualifying for an allowance under the German Research Allowance Act, we recognized €5.1 million in income relating to expenses, eligible for reimbursement, which were incurred in the years 2020 to 2024. We remain eligible for additional research allowances for eligible expenses to be incurred from 2025 to 2027.

Net financial result

Net financial result increased by €4.7 million to a gain of €6.9 million in 2024 compared to €2.2 million in 2023. This overall net increase is mainly attributable to an increase of €5.5 million in foreign exchange results, partially offset by €0.6 million lower interest income from marketable securities compared to 2023.

Net loss

We incurred a net loss of €46.1 million, or €0.78 per ordinary share, in 2024, compared to €42.7 million, or €0.78 per ordinary share, in 2023.

Liquidity and capital resources

As of December 31, 2024, our total funds available amounted to approximately €55.2 million, comprised of €18.4 million of cash and cash equivalents and €36.8 million of marketable securities.

Net cash used in operating activities

Net cash used in operating activities increased to €48.6 million in 2024, from €37.8 million in 2023, mainly due to lower income recognized from German federal government grants and research allowances

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 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)). 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 were 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 Food and Drug Administration (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.

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 pyoderma gangrenosum (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.
