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, company has announced that the European Commission (EC) has granted marketing authorization under exceptional circumstances for GOHIBIC (vilobelimab) for the treatment of adult patients with SARS-CoV-2-induced acute respiratory distress syndrome. The EU approval of GOHIBIC is supported by the previously announced results of the multicenter Phase 3 PANAMO trial.

According to an InflaRx media release, in October 2024, the Committee for Medicinal Products for Human Use (CHMP) convened to review the MAA; the regulatory process continues with discussions ongoing between the Company and the CHMP, with a CHMP opinion anticipated around the middle of November.

According to an InflaRx media release, based upon data from this trial ; the Company has submitted a Marketing Authorization Application (MAA) for the treatment of adult patients with SARS-CoV-2 induced septic 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).

According to an InflaRx media release, company is continuing discussions with the FDA related to the submission of a Biologics License Application (BLA) for a potential future full approval of Gohibic.

According to an InflaRx media release, an Emergency Use Authorization (EUA) has been granted by the US Food and Drug Administration (FDA) for Gohibic (vilobelimab) for treatment of coronavirus disease 19 (COVID-19) in hospitalized adults when initiated within 48 hours of receiving invasive mechanical ventilation (IMV), or extracorporeal membrane oxygenation (ECMO). Also, Gohibic has not been approved but has been authorized for emergency use by FDA under an EUA. The data supporting the EUA were based on the previously announced results published in The Lancet Respiratory Medicine.

According to an InflaRx media release, the company has submitted a request for Emergency Use Authorization (EUA) following encouraging interactions with the US Food and Drug Administration (FDA) at a Type B meeting held this summer.

According to an InflaRx media release, vilobelimab has been granted FDA Fast Track designation to treat critically ill COVID-19 patients based on the results of this study.

According to an InflaRx media release, the company plans to submit a request for Emergency Use Authorization (EUA) following encouraging Type B meeting with US FDA. In the meeting with the FDA, the company discussed in detail the completed Phase III part of the PANAMO study in invasively mechanically ventilated, critically ill COVID-19 patients. Application for EUA planned to be submitted in Q3 2022

Results

Therapeutic efficacy

Updated results from the phase II/III PANAMO trial showed that direct C5a inhibition by vilobelimab resulted in a survival benefit for critically ill COVID-19 Pt without increasing infections. Kaplan-Meier estimates showed a 28-Day mortality rate of 31.7% for Vilo vs 41.6% for Plc [HR 0.67 (95% CI: 0.48, 0.96), p< 0.05] with similar 60-Day results. On Day 8 after 3 infusions, mean vilobelimab trough levels were 21,799.3 to 302,972.1 ng/mL (geometric mean 137,881.3 ng/mL). C5a was highly elevated and comparable between groups at screening. By Day 8, C5a levels were reduced 87% for vilobelimab (mean 16.8 ng/mL, p< 0.001) vs an increase for Plc (mean 129.8 ng/mL). Though post Day 8 sampling was sparse, C5a levels remained elevated for Plc and low for vilobelimab throughout the study [2] Updated results from the phase II/III PANAMO trial demonstrated that vilobelimab significantly reduced mortality at 28 and 60 days in critically ill COVID-19 patients with no increase in infections suggesting the importance of targeting C5a while preserving MAC. The 28-d all-cause mortality was 31.7% with vilobelimab vs 41.6% with placebo (P) (Kaplan-Meier estimates; Cox regression site-stratified, HR 0.73; 95% CI:0.50-1.06; P = 0.094), representing a 23.8% relative mortality reduction. In predefined primary outcome analysis without site stratification, however, vilobelimab significantly reduced mortality at 28 (HR 0.67; 95% CI:0.48-0.96; P = 0.027) and 60 days (HR 0.67; 95% CI:0.48-0.92; P = 0.016). Vilobelimab also significantly reduced 28-d mortality in more severe patients with baseline WHO ordinal scale score of 7 (n = 237, HR 0.62; 95% CI:0.40-0.95; P = 0.028), severe ARDS/PaO2/FiO2 ≤ 100 mmHg (n = 98, HR 0.55; 95% CI:0.30-0.98; P = 0.044) and eGFR < 60 mL/min/1.73m2 (n = 108, HR 0.55; 95% CI:0.31-0.96; P = 0.036) [3] . Previous results from the phase II/III PANAMO trial demonstrated that the vilobelimab treatment resulted in a relative reduction in 28-day all-cause mortality of 23.9% compared to placebo (vilobelimab 31.7% versus placebo 41.6%, p=0.094), which was not statistically significant using site-stratified cox regression analysis as pre-specified in the final statistical analysis plan. The original protocol-specified analysis would have resulted in a statistically significant p-value of 0.027. Additionally, logistic regression analyses of 28-day all-cause mortality resulted in p-values of <0.05 for 3 out of the 4 pre-specified analyses. Importantly, 60-day all-cause mortality, a key secondary endpoint, showed a continued reduction of mortality in the vilobelimab arm [4] . Efficacy data obtained from phase II/III trial indicated relative reduction in 28-day all cause mortality of 43% (vilobelimab 21.2% versus placebo 37.2%, p=0.014, hazard ratio: 0.5) in patients with severe acute respiratory distress syndrome (ARDS) and PaO2/FiO2 <100 (n=98, p=0.044); in intubated patients suffering from one or more additional organ support captured as baseline ordinal scale of 7 (n=237, p=0.028); and in patients with kidney impairment, captured by estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73m² (n=108, p=0.036). As per site-stratified Cox regression analysis as pre-specified in the final statistical analysis plan of the study, this was not statistically significant. The statistical analysis method was changed from non-stratified to site-stratified as per the recommendation of the regulatory authorities. In pre-specified subgroup analysis in Western European patients, a 43% of relative reduction in 28-day all cause mortality was detected, when vilobelimab was compared with placebo treatment (n=209, p-value=0.014). The analysis was done in intubated patients suffering from one or more additional organ support. Earlier data from the part II of a phase II/III trials indicated 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 [5] [6] [7] .

Adverse events

Updated results from the phase II/III PANAMO trial demonstrated that vilobelimab was safe. Serious AEs were 58.9% for vilobelimab and 63.5% for Plc.Treatment-emergent AEs were 90.9% vilobelimab vs 91.0% placebo (P). Infections were comparable: vilobelimab 62.9%, P 59.3%. Infection incidence per 100 Pt days were equal [2] No meningococcal infections were reported. Serious AEs were 58.9% vilobelimab, 63.5% P [3] . Previous results 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 [7] .
