Pilot Study of Cefditoren Pivoxil in COVID-19 Patients With Mild to Moderate Pneumonia

COVID-19 Pneumonia Clinical Trial

Official title: Prospective, Non-controlled Pilot Study to Evaluate the Efficacy and Safety of Cefditoren Pivoxil in COVID-19 Patients With Mild to Moderate Pneumonia

Status Completed

Clinical Trial Summary

The global pandemic of novel coronavirus disease 2019 (COVID-19) began in Wuhan, China, in December 2019, and has since spread worldwide. The disease is mild in 85% of cases but the remaining 15% requires hospitalization and/or intensive care.

Recent publications show that a significant number of COVID-19 patients are co-infected with one or more pathogens. Most co-infections occurred within 1-4 days of onset of COVID-19 disease and a considerable number of patients arrive to the Emergency rooms with mild-moderate respiratory symptoms compatible with pneumonia of presumed bacterial origin and not severe enough for requiring hospitalization. It therefore seems reasonable to adopt therapeutic strategies for these patients that are effective and easy to follow in the outpatient setting.

Cefditoren (CDN) is a third-generation cephalosporin for oral administration. CDN has a broad spectrum of activity and is particularly active against the bacterial pathogens involved in community respiratory tract infections. Besides that, the use of CDN has been associated with a marked decrease in circulating levels of IL-6 and other pro-inflammatory cytokines and mediators of epithelial damage. The aim of this study is to demonstrate that CDN improves clinical condition in patients with mild-moderate COVID-19 and symptoms of bacterial pneumonia.

Clinical Trial Description

The global pandemic of novel coronavirus disease 2019 (COVID-19) began in Wuhan, China, in December 2019, and has since spread worldwide. The novel coronavirus is now referred to as severe and critical acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The disease is mild in 85% of cases but the remaining 15% requires hospitalization and/or intensive care.

Recent publications show that a variable number of COVID-19 patients are co-infected with one or more pathogens. Most co-infections occurred within 1-4 days of onset of COVID-19 disease and in a retrospective study, secondary infection was observed in 50% of non-survivor patients.

In COVID-19 patients the elevated inflammatory cytokines and other inflammatory mediators present suggest that a cytokine storm, also known as cytokine release syndrome (CRS), may play a major role in the pathology of this disease. The elevated cytokine levels, specifically IL-6, may also be responsible for the lethal complications of COVID-19. Therefore, the interleukin-6 (IL-6) blockade has been proposed as one of the strategies to manage COVID-19-induced CRS.

A considerable number of COVID-19 patients arrive to the Emergency rooms with mild-moderate respiratory symptoms compatible with pneumonia of presumed bacterial origin not severe enough for requiring hospitalization. It therefore seems reasonable to adopt therapeutic strategies for these patients that are effective and easy to follow in the outpatient setting to avoid overloading the Health System.

Cefditoren (CDN) is a third-generation cephalosporin for oral administration. CDN has a broad spectrum of activity and is particularly active against the bacterial pathogens involved in community respiratory tract infections. The results of clinical trials with CDN on community-acquired pneumonia showed percentages of clinical and microbiological efficacy around 85%. On the other hand, the use of CDN has been associated with a marked decrease in circulating levels of IL-6 and other pro-inflammatory cytokines and mediators of epithelial damage such as Krebs von den Lungen-6 (KL-6).

Considering the above and the current estate of knowledge against SARS-CoV-2, we have considered of relevance to study the efficacy of CDN in a series of patients with mild-moderate COVID-19 and with symptoms compatible with pneumonia of presumed bacterial origin, seen at the Emergency room of a public hospital and followed on outpatient basis. ;
