InflaRx Receives Positive CHMP Opinion for GOHIBIC® (Vilobelimab) for the Treatment of SARS-CoV-2-Induced Acute Respiratory Distress Syndrome

JENA, Germany, Nov. 15, 2024 (GLOBE NEWSWIRE) -- InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company pioneering anti-inflammatory therapeutics targeting the complement system, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending marketing authorization of GOHIBIC (vilobelimab), 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 Company expects the European Commission to adopt the positive opinion and issue a marketing authorization within 67 days.

Prof. Niels C. Riedemann, Chief Executive Officer and Founder of InflaRx, commented: "The positive CHMP opinion reflects a significant milestone in the development of our anti-C5a antibody vilobelimab, and, together with the previously received Emergency Use Authorization granted by the FDA, further validates its therapeutic potential. Patients in the ICU continue to die from SARS-CoV-2-induced ARDS, an important reminder of the ongoing need for more effective treatments for these patients. We are grateful to the intensive care physicians and patients' families who worked with InflaRx on the PANAMO study."

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's approval in the EU, which is anticipated early next year, 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.

InflaRx plans to commercialize the product in Europe under its proprietary brand name GOHIBIC^®. As previously indicated, InflaRx is considering commercial distribution options with potential partners in the EU. InflaRx does not expect this approach will have a meaningfully negative impact on its cash burn rate.

The positive CHMP opinion 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.

Important Information about GOHIBIC (vilobelimab)

GOHIBIC (vilobelimab) has been granted an Emergency Use Authorization by the U.S. 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 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 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 website (www.GOHIBIC.com).

Important Safety Information about GOHIBIC (vilobelimab)

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

GOHIBIC 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. Hypersensitivity reactions have been observed with GOHIBIC. If a severe hypersensitivity reaction occurs, administration of GOHIBIC 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 treatment and are considered to be potentially attributable to GOHIBIC.

Report side effects to the FDA at 1-800-FDA-1088 or www.FDA.gov/medwatch. In addition, side effects can be reported to InflaRx at: [email protected].

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.

In addition to development in COVID-19, vilobelimab is also 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.
