An international team of researchers has tested more than 10,000 compounds to identify six drug candidates that may help treat COVID-19.

The research, involving University of Queensland scientist Professor Luke Guddat, tested the efficacy of approved drugs, drug candidates in clinical trials and other compounds.

Chloroquine, hydroxychloroquine and azithromycin are being used to treat and prevent COVID-19 despite weak evidence for effectiveness, and physicians and patients should be aware of the drugs' potentially serious adverse events, states a review in CMAJ (Canadian Medical Association Journal).

A Lancaster University statistician who worked on the first published large randomised clinical trial for a potential treatment for the COVID-19 virus said the scientific community was coming together to combat the coronavirus. There are currently no specific treatments for COVID-19. However, it is possible that some existing drugs, usually used for other conditions, may have some benefits.

An international team led by University of British Columbia researcher Dr. Josef Penninger has found a trial drug that effectively blocks the cellular door SARS-CoV-2 uses to infect its hosts. The findings, published in Cell, hold promise as a treatment capable of stopping early infection of the novel coronavirus.

A collaborative study led by Monash University's Biomedicine Discovery Institute (BDI) in Melbourne, Australia, with the Peter Doherty Institute of Infection and Immunity (Doherty Institute), has shown that an anti-parasitic drug already available around the world kills the virus within 48 hours.

An antibody recovered from a survivor of the SARS epidemic in the early 2000s has revealed a potential vulnerability of the new coronavirus at the root of COVID-19, according to a study from scientists at Scripps Research.

The study, published today in Science, is the first to map a human antibody's interaction with the new coronavirus at near-atomic-scale resolution.

An international team including McMaster University researchers has come together to issue guidelines for health-care workers treating intensive care unit (ICU) patients with COVID-19. The Surviving Sepsis Campaign COVID-19 panel has released 54 recommendations on such topics as infection control, laboratory diagnosis and specimens, the dynamics of blood flow support, ventilation support, and COVID-19 therapy.
