In vitro Antiviral Activity of Kabasura Kudineer - Siddha Polyherbal Formulation Against Novel Coronavirus (SARS-CoV-2) (preprint)

Kabasura Kudineer (KSK) is a Sastric Siddha polyherbal formulation that has been used to treat the fever with influenza-like indication. The purpose of this study is to validate the antiviral activity of KSK against the novel SARS-CoV-2 virus. The antiviral activity of KSK against SARS-CoV-2 was assessed in Vero E6 cells and followed by an RT-PCR assay. KSK significantly inhibited SARS-CoV-2 replication in Vero E6 cells. These data indicate that KSK prevents the attack of its virus, rendering the use of these a novel COVID-19 infectious diseases strategy.

Characteristics of COVID-19 Clinical Trials in India Based on the Registration Data on CTRI (Clinical Trials Registry- India): a cross-sectional analysis (preprint)

Objectives: The 2019 pandemic of coronavirus disease (COVID-19) has prompted several efforts to find safe and effective drugs, but little is understood as to where early efforts were centered. Several clinical trials, both Allopathy and AYUSH medicines have been registered in the Clinical Trial Registry of India (CTRI). We aimed to characterize and extract relevant data registered under CTRI for COVID -19. Materials and Methods: A cross-sectional analysis was performed of clinical trials for the treatment of COVID-19 that were registered in the Clinical Trial Registry of India (CTRI) from 1st March 2020 to 22nd June 2020. Relevant trial records were downloaded, deduplicated, and independently analyzed by three reviewers. Main outcomes: Trial intervention, design, sponsorship, phase of the trial, and indicated outcomes. Results: 233 COVID-19 clinical trials, was registered from India in CTRI. Out of these, 146 were Interventional trials, 84 Observational trials, and three Post-marketing surveillance. Questionnaire and survey-based intervention occupy a significant portion. Randomized control trials are large in number 37.8% than non-randomized. 20% of the trials were recruiting patients, and the Research institution (34%) sponsored more than half of the trials. Global trials are minimal, occupying 3% of total trials and Indian trials were 97%. In most of the trials, the interventional agent is either multiple drug combinations or compound drug formulations compared to single drug administration. Among the trials, 46 Allopathic interventions, 41 Ayurveda interventions, 14 Homeopathy interventions, one in Unani, and 2 in yoga and Naturopathy. Conclusion: This study will provide a background of COVID-19 clinical trials registered in CTRI and provide specific issues observed related to clinical trial designs, which offer information to perform clinical trials on COVID-19 Keywords: COVID-19, CTRI, Clinical Trial Registry of India, Ministry of AYUSH, Clinical trial, Interventional, Randomized, Blinding.
