There are numerous ongoing studies assessing treatment options for preventing, treating, and managing complications of coronavirus disease-2019 disease. The objective of this study was to do a systematic review and critical appraisal of the ongoing clinical trials with an aim to provide insight into the various interventions tested, clinical rationale, geographical distribution of the trials as well as the endpoints assessed in the studies. ClinicalTrials.gov, World Health Organization International Clinical Trials Registry Platform, and PubMed were assessed till 11 May 2020. The search resulted in 3242 ongoing studies of which 829 studies were included. There are 134 different drug-based interventions being assessed in 463 clinical trials as treatment options China accounts for 35% of all ongoing clinical studies followed by USA 23% and other countries together account for 42%. Amongst the 463 studies assessing drug-based treatment options, studies that are funded by federal and academic institutions are 79.6%, pharmaceutical company-funded studies are 15.11%, and no funding information is available in 5.10%. The definitive outcomes like mortality are being assessed as primary outcome in 22.8% of the studies only and need for ventilator in 6.2% of the studies. Amongst the pharmaceutical company-funded drug-based studies, only 20% of the studies had mortality as the primary outcome. Only 5.5% of the ongoing clinical trials are specifically designed to assess the most vulnerable population like elderly, patients with comorbidities and cancer. Multiple intervention-based clinical studies against severe acute respiratory syndrome-related coronavirus-2 are being performed throughout the world with a high concentration of clinical trials in the developed world with concern that of elderly and patients with comorbidities are being underrepresented and definite endpoints like mortality are being assessed in only one-fifth of the studies.
