A Study of Hydroxychloroquine versus Placebo to Prevent COVID-19 Infection in Patients Receiving Radiation Therapy

Trial Status: administratively complete

This phase II trial studies how well hydroxychloroquine works in preventing infection with the COVID-19 virus in patients receiving radiation therapy. Hydroxychloroquine has been approved for the prevention and treatment of malaria, and the treatment of lupus and rheumatoid arthritis. Receiving radiation therapy may increase the risk of infection with the COVID-19 virus because the patients are in frequent and close contact with healthcare workers and with other patients who may have become infected. Patients receiving treatment for cancer may also have weakened immune system. Giving hydroxychloroquine may help prevent infection with SARS-CoV-2 in patients who are receiving radiation therapy for their cancer.
