Background

Vilobelimab is a chimeric monoclonal immunoglobulin G4 (IgG4) antibody that binds to the soluble form of human C5a with high affinity. It consists of mouse anti-human complement factor 5a (C5a) monoclonal binding sites (variable regions of heavy and light chain regions) and human gamma 4 heavy chain and light kappa chain constant regions. In April 2023, the FDA issued an emergency use authorization (EUA) for vilobelimab for the treatment of COVID-19 in hospitalized adults requiring mechanical ventilation or artificial life support. The drug is not yet fully approved for this condition.

Indication

Vilobelimab is used for emergency use to treat coronavirus disease 19 (COVID-19) in hospitalized adults when initiated within 48 hours of receiving invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO). However, vilobelimab is not FDA-approved for this use.

InflaRx's Gohibic Receives EU Approval for COVID-19-Induced ARDS, Bolstering Market Potential

• InflaRx's Gohibic is the first and only treatment approved in the EU for SARS-CoV-2-induced ARDS, marking a significant milestone. • The European Commission's approval was based on positive Phase 3 PANAMO trial results, demonstrating a 23.9% reduction in mortality. • H.C. Wainwright reiterated a Buy rating for InflaRx, setting a price target of $8.00, citing Gohibic's market potential and pipeline. • InflaRx is exploring partnership and distribution options in Europe and is in discussions with the FDA for potential US approval.

InflaRx's Gohibic (vilobelimab) Receives European Commission Approval for SARS-CoV-2-Induced ARDS

• InflaRx's Gohibic (vilobelimab) has been granted marketing authorization in the EU for treating SARS-CoV-2-induced acute respiratory distress syndrome (ARDS). • This approval makes Gohibic the first and only treatment approved in the European Union for this specific condition, addressing a critical unmet need. • The approval is based on Phase 3 PANAMO trial results, demonstrating a 23.9% relative reduction in 28-day all-cause mortality compared to placebo. • Gohibic is intended for adult patients receiving systemic corticosteroids and invasive mechanical ventilation, with or without extracorporeal membrane oxygenation.

Site-Stratified Cox Regression Analysis Limitations Impact COVID-19 Mortality Study

• Site-stratified Cox regression in the PANAMO phase III study led to data attrition, excluding 16.6% of patients and compromising the p-value. • Exclusion of data from sites with no events or single patients underestimated the treatment effect of vilobelimab on COVID-19 mortality. • Cox regression without site stratification reported a positive finding (HR 0.67, p=0.026), which was considered more reliable by the FDA. • Country-level or region-level stratification may be more appropriate to account for geographic diversity and population heterogeneity.
