Phase <scp>III</scp> randomized clinical trial of <scp>BV</scp>‐4051, an Ayurvedic polyherbal formulation in moderate <scp>SARS‐CoV</scp>‐2 infections and its impact on inflammatory biomarkers

SARS-CoV-2 virus and its variants continue to be a challenge inspite of widespread vaccination and preventive measures. We hypothesized an oral, safe polyherbal formulation with antiinflammatory properties may improve the clinical outcome of this disease. BV-4051, a formulation from four Ayurvedic plants namely Ashwagandha, Boswellia, Ginger and Turmeric was used for the treatment of hospitalized moderate COVID-19 patients along with standard of care (SOC). Patients were randomly assigned to receive BV-4051 or placebo tablets for 14 days, at four sites in India during late 2020 to early 2021. Among 208 randomized subjects, 175 completed the study. In BV-4051 group the mean reduction in duration of illness (p = 0.036), alleviation and severity scores of several symptoms like fever, cough, smell, and taste disorders were statistically significant (p ≤ 0.05). A sub-set analysis of subjects treated with or without Remdesivir as SOC showed mean reduction in duration of illness in BV-4051 (p = 0.030), and severity scores (p ≤ 0.05). Mean difference in Interleukin-6 was statistically significant (p = 0.042) on BV-4051 without Remdesivir. BV-4051 may reduce duration of illness, symptoms severity, Interleukin-6, and prevent the incidence of COVID-19 complications. It may have an adjunctive effect with other SOC. Larger extensive clinical testing may give a better understanding of its effect.
