InflaRx Announces Initiation of Phase III Part of Phase II/III Clinical Trial with IFX-1 in Severe COVID-19 Induced Pneumonia
First site initiated for enrollment in the Netherlands
Regulatory approval granted to start trial in Germany
Additional sites to be added in the US, EU and other regions
Encouraging Phase II data accepted for publication in The Lancet Rheumatology
Jena, Germany, 14 September 2020 – InflaRx (Nasdaq: IFRX), a clinical-stage biopharmaceutical company developing anti-inflammatory therapeutics by targeting
the complement system, announced today the start of the global Phase III part of its Phase II/III trial with IFX-1 in severe COVID-19 induced pneumonia with the initiation of the first clinical site in the Netherlands. In parallel, the German
regulatory authority, the Paul-Ehrlich-Institut (PEI), has approved the Phase III clinical trial in Germany.
The randomized, double-blinded and placebo - controlled Phase III part of the Phase II/III trial plans to enroll approximately 360 early intubated, critically ill patients with COVID-19 induced
pneumonia across sites in the US, EU, South America and other regions. Patients will be randomized 1:1 to receive either IFX-1 or placebo; all patients will receive standard of care. The primary endpoint will be 28-day all-cause mortality; key
secondary endpoints will include assessment of organ support and disease improvement. An interim analysis is planned after enrollment of 180 patients, with a potential for an early stop for efficacy or futility.
Dr. Korinna Pilz, Global Head of Clinical R&D at InflaRx, noted: “Encouraged by our initial Phase II results, we are now rolling out the international Phase III part of the trial. Our team is
driven by the prospect of adding to the global efforts in the fight against this pandemic and by advancing the development of a potential therapeutic for the sickest COVID-19 patients.”
The data from the Phase II part of the study, which evaluated IFX-1 treatment plus best supportive care and best supportive care alone in 30 patients, have been accepted for publication in the
peer-reviewed journal, The Lancet Rheumatology.
Dr. Alexander Vlaar, the principal investigator of the study from Amsterdam University, Department of Intensive Care Medicine, commented: “We are very pleased that a distinguished, peer-reviewed journal has recognized the significance of the Phase II
data for patients with severe COVID-19 induced pneumonia. The results demonstrate promising early efficacy signals, including lower mortality and organ dysfunction rates, and suggest that C5a inhibition might be beneficial in critically ill COVID-19
patients. However, these effects need to be confirmed in the large, well-powered Phase III part of the trial.”
IFX-1, which has recently been granted the International Nonproprietary Name (INN), vilobelimab, currently has additional ongoing Phase II studies in ANCA-associated vasculitis and Pyoderma Gangraenosum and has
completed Phase IIb development in Hidradenitis Suppurativa, for which a Phase III clinical development strategy is currently being developed.
IFX-1 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, IFX-1 leaves the formation of the membrane attack complex (C5b-9) intact as an important defense mechanism, which is not the case for molecules blocking the cleavage of C5. IFX-1 has been demonstrated to control the inflammatory response driven
tissue and organ damage by specifically blocking C5a as a key “amplifier” of this response in pre-clinical studies. IFX-1 is believed to be the first monoclonal anti-C5a antibody introduced into clinical development. Approximately 300 people have
been treated with IFX-1 in clinical trials, and the antibody has been shown to be well tolerated. IFX-1 is currently being developed for various indications, including Hidradenitis Suppurativa, ANCA-associated vasculitis, Pyoderma Gangraenosum and
InflaRx (Nasdaq: IFRX) is a clinical-stage biopharmaceutical company focused on applying its proprietary anti-C5a technology to discover and develop first-in-class, potent and specific inhibitors of C5a. Complement C5a
is a powerful inflammatory mediator involved in the progression of a wide variety of autoimmune and other inflammatory diseases. InflaRx was founded in 2007, and the group has offices and subsidiaries in Jena and Munich, Germany, as well as Ann
