IFRX InflaRx NV

InflaRx N.V. (Nasdaq: IFRX), a biopharmaceutical company developing anti-inflammatory therapeutics by targeting the complement system, announced today the commercial launch of Gohibic (vilobelimab) in the U.S. In April 2023, Gohibic was granted an Emergency Use Authorization (EUA) 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 invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO).

Prof. Niels C. Riedemann, Chief Executive Officer and Founder of InflaRx, commented: “We are excited to make Gohibic available to certain critically ill COVID-19 patients in the U.S. Our team is proud to contribute to the fight against this terrible virus with a potentially lifesaving therapeutic option for some of the most critically ill COVID-19 patients.”

The data supporting the EUA were based on the previously announced results of the multicenter Phase III PANAMO trial, which 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 have been published in The Lancet Respiratory Medicine.

Gohibic is currently the only drug directed against the complement factor C5a that is authorized for the treatment of certain critically ill COVID-19 patients. InflaRx is continuing discussions with the FDA related to the submission of a Biologics License Application (BLA) for a potential future full approval of Gohibic.

Dr. Thomas Taapken, Chief Financial Officer of InflaRx, commented: “We have built an excellent core commercial team to support the launch and distribution to U.S. hospitals. We also have worked out a time- and cost-efficient model for distribution. We continue to adapt our investments to create a commercial and logistical infrastructure as well as additional manufacturing capacity.”

InflaRx has also completed encouraging meetings with the rapporteur and co-rapporteur member state teams of the European Committee for Medicinal Products for Human Use (CHMP) related to a planned Marketing Authorization Application with the European Medicines Agency (EMA). The Company will provide updates on the status of regulatory submissions in the U.S. and elsewhere once available.

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.

Important Information about Gohibic (vilobelimab)Vilobelimab is a first-in-class monoclonal anti-human complement factor C5a antibody that has been granted an EUA for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO.

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 adverse events or deaths occurring during Gohibic treatment and 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: pvusa@inflarx.de

About Viral Sepsis in SARS-CoV-2 Infection

Invasively mechanically ventilated patients who have tested positive for COVID-19 fulfill the criteria set by the current third international consensus definitions for sepsis, which define sepsis as a “life-threatening organ dysfunction caused by a dysregulated host response to infection.” Viral infection-mediated sepsis is believed to be driven by the inflammatory immune response of a patient to the virus. Observational studies have suggested that the inflammatory response, endothelial permeability and coagulopathy observed in severe COVID-19 are associated with strong complement activation and C5a generation as part of the human innate immune response. By targeting the complement component C5a in critically ill and invasively mechanically ventilated COVID-19 patients, vilobelimab is believed to block a key mediator of this inflammatory host response induced by severe SARS-CoV-2 infection and, thus, potentially offers a mechanism of action that may be independent of the viral variant that has caused such inflammatory response. Inhibition of the C5a / C5aR pathway has been demonstrated to be beneficial or lifesaving in various pre-clinical models of viral lung injury and viral sepsis, including models investigating influenza and corona viruses.

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 and cutaneous squamous cell carcinoma.
