Trial Overview

Purpose

Phase II & Phase III: This is a pragmatic, adaptive, randomized, multicenter phase II/III study evaluating IFX-1 for the treatment of COVID-19 related severe pneumonia. The study consists of two parts: Phase II, an open-label, randomized, 2-arm phase evaluating best supportive care (BSC) + IFX-1 (Arm A) and BSC alone (Arm B); and Phase III, a double-blind, placebo-controlled, randomized phase comparing standard of care (SOC) + IFX-1 (Arm A) versus SOC + placebo-to-match (Arm B)

Comments

According to an InflaRx media release, phase III part of this study is subject to regulatory approval.

Primary Endpoints

Phase II

The primary endpoint in Phase II was the relative change (%) from baseline (day 1 prior to study drug administration at ± 1h of randomization) in Oxygenation Index (PaO2 / FiO2) in supine position at day 5.

Phase III: Mortality

description: 28-day all-cause mortality
Based on the preliminary interim analysis of efficacy data from Phase II, the primary endpoint chosen for Phase III is 28-day all-cause mortality.
time_frame: Day 28

Other Endpoints

Treatment Emergent Adverse Events

Results

Therapeutic efficacy

In a part II of a phase II/III trials, being conducted in patients with severely progressed pneumonia associated with COVID-2019 infections, twenty-eight-day all-cause mortality in the vilobelimab treatment group was 13% (2 out of 15) versus 27% (4 out of 15) in the control group. In a vilobelimab treatment group, a higher number of patients with 2 or more comorbidities associated with increased COVID-19 mortality were reported, compared to best supportive care group. In the vilobelimab treatment group fewer patients experienced renal impairment assessed by estimated glomerular filtration rates and more patients showed reversal of blood lymphocytopenia and a greater lowering of lactate dehydrogenase concentrations as a sign of reduction in tissue damage. A temporary, but statistically significant increase of D-dimer levels in the first days following vilobelimab administration was reported, as a potential signal for induction of blood clot lysis. No statistically significant group differences on the relative percentage change from baseline to day five in oxygenation index (defined as PaO2/FiO2 ratio) were detected^[2]^[3].

Adverse events

In a part II of a phase II/III trials, being conducted in patients with severely progressed pneumonia associated with COVID-2019 infections, vilobelimab treatment was well tolerated. There was one death in vilobelimab treatment arm after acute ventilator tube complication (leakage), the other death was due to pulmonary failure in patient with history of severe COPD. In the best supportive care group, there were four deaths due to COVID-2019 induced multi-organ failure. Three of these four were due to pulmonary embolisms as an SAE. Adverse events were comparatively lower in vilobelimab group^[3].
