SARS-CoV2 Infection Clinical Trial

Official title: A Randomized, Double-blind, Placebo-controlled Study to Evaluate the Efficacy of Aerosolized Novaferon in Asymptomatic and Mildly Symptomatic Patients Infected With SARS-CoV-2.

Clinical Trial Summary

This is a phase III randomized, double blinded, placebo-controlled multi-center study to assess the efficacy and safety of aerosolized Novaferon for the treatment of asymptomatic or mildly patients infected with SARS-CoV-2.

Clinical Trial Description

Since the outbreak of New Coronavirus pneumonia (COVID-19) in late 2019, epidemics around the world are still developing. There are about 200 million confirmed cases in the world, including about 4.26 million deaths until August 5, 2021, which has become a major disaster for human being.

Most of SARS-CoV-2 infection are asymptomatic or mild cases, which is the main factor causing viral transmission. Although COVID-19 patients have immune protection after cured or vaccinated, there still be a percentage of people vaccinated who still get sick, hospitalized, or die caused by COVID-19. COVID-19 vaccine breakthrough and reinfection cases became one of key problems for COVID-19 prevention and control. In addition, SARS-CoV-2 variants circulated in the world. However, some variants were associated with disease severity, the performance of vaccines, therapeutic medicines, diagnostic tools, or other public health and social measures. Variants (e.g., Delta variant) caused some vaccine breakthrough cases. There is an urgent need for effective antiviral drugs.

Novaferon is a marketed antiviral drug in China and proved to have more than ten-fold antiviral potency than that of similar interferon α-2b. Novaferon exerts antiviral activity by three ways: blocking virus entry into cells, inducing expression of antiviral genes and proteins (e.g., MX1 and OAS), and promoting apoptosis of infected cells. In vitro experimental study showed Novaferon exhibited anti-SARS-CoV-2 effects at the cellular level. A randomized, open-label, parallel-group trial demonstrated that aerosolized Novaferon expedited clearance and negative conversion of SARS-CoV-2, which provide the rational for large-scale clinical studies to verify the efficacy of Novaferon as a potential antiviral drug for COVID-19. Inhalation administration has advantages over systemic administration in reducing adverse drug reactions, promoting the distribution of drugs in respiratory tract, and thus enhancing the mucosal immunity.

This is a phase III randomized, double blinded, placebo-controlled multi-center study to assess the efficacy, and safety of aerosolized Novaferon for the treatment of asymptomatic patients or patients with mild COVID-19. ;
