In search for a panacea for coronavirus disease-19

Abstract

OBJECTIVE: To analyze the clinical trials that are registered on the Clinical Trial Registry of India (CTRI) portal for a year, for the treatment, prevention, and supportive therapy of coronavirus disease-19 (COVID-19). MATERIALS AND METHODS: All the trials registered on CTRI (since January 2020 till January 2021) for therapeutic, preventive, and supportive interventions for COVID-19 were searched with the keywords “Coronavirus,” “COVID-19,” “SARS-COV-2,” and “2019-nCoV”. These registered studies were analyzed as follows: Trials under different systems of Medicine-Allopathy/Homeopathy/Ayurveda/Unani/Yoga/Naturopathy. The Allopathy trials were further analyzed in detail: Intervention, design, comparator, number of subjects, duration, and approvals taken. RESULTS: A total of 1597 records were found. After excluding the overlaps, behavioral and other studies conducted to understand the diagnosis, epidemiology, a total of 419 registered studies were included for further analysis. Out of these 419 studies, 166 (39.6%) were in Ayurveda, 154 (36.7%) in Allopathy, 33 (7.8%) in Homeopathy, 30 (7%) in Unani/Siddha, 18 (4.3%) in Yoga and Naturopathy and 18 (4.3%) in Nutraceuticals. A total of 264 interventions had been registered in 419 clinical trials. Sixty-seven interventions were being studied under allopathy in 154 studies. Same product was being evaluated in differently designed protocols with different endpoints. Maximum number of trials and subjects were for Hydroxychloroquine 25 (17,998), Ivermectin 11 (2820), Convalescent Plasma 11 (3982), Remdesivir 8 (3725), Tocilizumab 6 (884), and Azithromycin 6 (582). CONCLUSIONS: In response to the COVID-19 pandemic, Indian researchers came forward from all the systems of medicine to evaluate interventions for prophylaxis or treatment of the disease. The involvement of AYUSH systems of medicine was specifically more in this regard. A wide variation and heterogeneity in doses and outcomes were observed in trial designs which might make it difficult to generalize the study results when they are made available. Urgent analyses of studies involving interventions on the treatment advisory of the Government may help the healthcare providers take more informed decisions for managing COVID-19 patients in India.
