InflaRx Announces Vilobelimab Phase III Results in Critically Ill COVID-19 Patients Published in The Lancet Respiratory Medicine
| • |
In-depth statistical analysis confirms robustness of clinical survival benefit of vilobelimab treatment on 28-day and 60-day all-cause mortality
|
| • |
Vilobelimab targets the inflammatory immune response evoked by SARS-CoV-2 infection that causes viral sepsis leading to organ failure
|
Jena, Germany, September 08, 2022 – InflaRx N.V. (Nasdaq: IFRX), a clinical-stage biopharmaceutical company developing anti-inflammatory therapeutics by targeting the complement system, today announced that the previously reported results from its Phase III trial of
vilobelimab to treat critically ill, invasively mechanically ventilated COVID-19 patients have been published in the peer-reviewed journal, The Lancet Respiratory Medicine.
The publication can be accessed free of charge on The Lancet’s website.
Professor Dr. Martin Witzenrath, Co-chair of the Department of Infectious Diseases and Respiratory Medicine, Charité Universitätsmedizin Berlin,
Germany, and investigator of the PANAMO study, commented: “We remain in urgent need of treatments that can help the most severely affected critically ill and invasively ventilated COVID-19 patients who suffer from a viral sepsis induced lung failure
and who still show high mortality rates in the range of 40% despite the applied standard of care. The results of the PANAMO trial demonstrate a robust signal for improved survival with C5a inhibition in these highly vulnerable patients.”
The article describes the results from the Phase III, multicenter, randomized, double-blind, placebo-controlled PANAMO study. The PANAMO study is
one of the largest 1:1 randomized, double-blind placebo-controlled trials that was powered to show a mortality difference as primary outcome measure in invasively mechanically ventilated COVID-19 patients in the intensive care unit. A total of 369
patients with COVID-19 on invasive mechanical ventilation were randomly assigned (1:1) to the vilobelimab treatment (six 800-mg infusions) or placebo group on top of standard of care, which included treatment with anti-coagulants, dexamethasone and
immunomodulators. The published data show 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.

In-depth statistical analysis confirms robustness of clinical survival benefit
The primary statistical analysis of the primary outcome 28-day mortality pre-specified in the statistical analysis plan (SAP) yielded a p-value of
0.0941 and, thus, missed the significance level. However, the original per-protocol planned method (p=0.0266), as well as multiple other comparable pre-specified or post-hoc analyses, yielded p-values of <0.05 or <0.01. In depth analyses of
this discrepancy suggest that the reported statistical p-value difference could be explained by the fact that, in the SAP defined model (site-stratified Cox regression), 61 patients from smaller sites with no occurring deaths or single patient sites
regardless of outcome (alive or dead) made no factual contribution to the analysis (to the p-value) because of the statistical algorithm applied when including site stratification in the analysis.
All comparable statistical analysis methods applied (different other Cox regression without site stratification) to which all 368 randomized
patients in the trial contributed to the p-value, and multiple other pre-specified and post-hoc analyses resulted in p-values below 0.05 or 0.01, confirming a robust signal for the observed survival benefit under vilobelimab treatment when compared
to placebo (as shown in the table below).

Comparable findings were made when applying the corresponding analysis to the key secondary endpoint, 60-day all-cause mortality, with even lower
p-values, for which a maintained relative reduction in mortality by vilobelimab compared to placebo treatment was detected (relative reduction of 22.6% using Kaplan Meier analysis).
A particularly strong relative reduction in 28-day all-cause mortality for vilobelimab treatment over placebo of 43% was reported for the
pre-specified Western European region analysis (p-value=0.014). In addition, three pre-specified subgroup analyses for patients of higher severity all showed a reduction in 28-day all-cause mortality with vilobelimab compared to placebo (p<0.05
for all three). The need for renal replacement therapy as a secondary endpoint was lower in vilobelimab-treated patients compared to the placebo group (p<0.05).
“The results of this Phase III trial show the life-saving potential of vilobelimab in treating these highly vulnerable, invasively mechanically
ventilated COVID-19 patients, and we are very happy that the importance of these data has now been recognized through publication by a top research journal after having gone through a rigorous review process,” said Prof. Niels C. Riedemann, CEO and
Founder of InflaRx. “Critically ill COVID-19 patients are believed to suffer from a septic inflammatory immune response to SARS-CoV-2 leading to C5a generation. Vilobelimab is therefore ideally positioned to provide a mechanism of action offering
benefit to patients suffering from the damaging effects of their own immune response to the virus,” he added.
Following encouraging interactions with the U.S. Food and Drug Administration (FDA) at a recent Type B meeting, the Company recently reported it
plans to submit a request for emergency use authorization with the FDA by end of Q3 2022.
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 3rd international
consensus definitions for sepsis and septic shock, 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 complement activation and C5a generation, as part of
the human innate immune system and its inflammatory response. By targeting the complement component C5a in critically ill and invasively mechanically ventilated patients, vilobelimab blocks a key mediator of this inflammatory host response induced by
severe SARS-CoV-2 infection and thus offers a mechanism of action which may be independent of the viral variant which has caused this response, once initiated.

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, which is not the case for molecules blocking the cleavage of C5. Vilobelimab
has been demonstrated in pre-clinical studies to control the inflammatory response driven tissue and organ damage by specifically blocking C5a as a key “amplifier” of this response. Vilobelimab is believed to be the first monoclonal anti-C5a antibody
introduced into clinical development. Vilobelimab has been shown to be well tolerated within clinical trials in different disease settings. Vilobelimab is currently being developed for various indications, including pyoderma gangrenosum (PG) and
severe COVID-19. The Company has recently reported positive Phase IIa results in PG and encouraging Phase III results in mechanically ventilated COVID-19 patients. Vilobelimab is also in Phase II development for patients suffering from cutaneous
squamous cell carcinoma.
