Hydroxychloroquine Chemoprophylaxis for COVID-19 Infection in High-risk Healthcare Workers.

• Status: Not yet recruiting
• Trial end date: 2020-10-15
• Target enrollment: 0
• Participant gender: All

Summary

Healthcare personnel are at an increased risk of exposure to SARS-CoV-2 infection while handling such patients. Currently, there is no treatment available for SARS-CoV-2 and stringent preventive measures are advised to avoid or minimize risk of exposure to healthcare workers. There are in vitro studies available which show inhibition of corona virus by hydroxychloroquine, a widely-used agent against malaria and certain autoimmune conditions and of low-cost and limited toxicity. However, evidence regarding its effects in patients is limited. We plan to conduct a randomized controlled trial to evaluate the safety and potential prophylactic efficacy of hydroxychloroquine in preventing secondary SARS-CoV-2 infection among healthcare workers at high-risk of exposure while managing such patients.
