• MAA for vilobelimab was submitted in July
  
• MAA has been validated by EMA and is now under review
• Regulatory submission based on pivotal data from PANAMO Phase III trial
• Company announces attendance at upcoming scientific and investor events

JENA, Germany, Aug. 30, 2023 (GLOBE NEWSWIRE) -- InflaRx N.V. (Nasdaq: IFRX), a biotechnology company pioneering anti-inflammatory therapeutics targeting the complement system, announced today that the Company has submitted a Marketing Authorization Application (MAA) for the treatment of adult patients with SARS-CoV-2 induced septic acute respiratory distress syndrome (ARDS) receiving invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO) and that the European Medicines Agency (EMA) has validated the MAA. This means that the application is now under regulatory review by the European Committee for Medicinal Products for Human Use (CHMP) under the centralized procedure, which applies to all 27 member states of the European Union (EU).

InflaRx submitted the MAA to EMA in July 2023 following interactions with the rapporteur and co-rapporteur teams of the CHMP. The MAA submission is based on the previously announced results of the multicenter Phase III 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.

“We are pleased that EMA has accepted our MAA submission and that it is now under review. By targeting the complement component C5a, vilobelimab blocks what is believed to be a key mediator of the tissue damaging inflammatory host response induced by severe SARS-CoV-2 infection. Based on the data from our Phase III trial, we believe that our treatment approach can make a meaningful difference for critically ill COVID-19 patients who are invasively mechanically ventilated,” said Dr. Camilla Chong, Chief Medical Officer of InflaRx.

“We look forward to continuing to work closely with EMA throughout the MAA review process, which is another important step toward our goal of bringing a potential treatment option to certain critically ill COVID-19 patients in Europe after having recently received an Emergency Use Authorization (EUA) in the United States,” added Derval O’Carroll, Senior Vice President and Global Head of Regulatory Affairs & Compliance at InflaRx.

Gohibic (vilobelimab) has received an EUA in the U.S. for the treatment of COVID-19 in hospitalized adults when initiated within 48 hours of receiving IMV or ECMO. The Company is continuing discussions with the Food and Drug Administration (FDA) related to the submission of a Biologics License Application (BLA) for a potential future full approval of Gohibic (vilobelimab) in the United States.

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.

The COVID-19 related work described herein is partly funded by the German Federal Government through grant number 16LW0113 (VILO-COVID). All responsibility for the content of this work lies with InflaRx.

About InflaRx
