Coronavirus disease 2019(COVID-19) is a global health emergency of serious health concern. However, there is no current medical treatment, although it is much needed for patient contracting the severe form of the disease. This systematic review was to explain the information regarding chloroquine for the treatment of COVID-19 via the data obtain from PubMed and other three trial Registries which were searched for review and the use of chloroquine in patients with COVID-19. Four articles were included (one narrative letter, one in-vitro study, one commentary and one editorial) and review on other 14 ongoing clinical trials in China. Chloroquine seems to have great potential in reducing the replication of SARS-CoV-2 (virus causing COVID-19) in vitro. There is high chance, pre-clinical evidence of effectiveness and information of safety from long-time clinical use for other indications to describe the clinical research on Chloroquine in patients with COVID-19. However, clinical description should either adhere to the Monitored Emergency Use of Unregistered Interventions (MEURI) framework or be ethically approved as a trial as stated by the World Health Organization. Safety data and data from high-quality clinical trials are urgently needed.
