The drug hydroxychloroquine, once touted by Donald Trump as a pandemic “game-changer,” should not be used to prevent Covid-19 and has no meaningful effect on patients already infected, a World Health Organization expert panel said.

A single-patient study conducted by British scientists found that Gilead’s remdesivir could be highly effective against Covid-19, raising questions about previous studies that found the antiviral drug had no impact on death rates from the disease.

Once touted as promising treatments and by some even a cure, the World Health Organization dashes those claims, finding no benefit in the use of four popular Covid-19 treatments (remdesivir, hydroxychloroquine, lopinavir, or interferon-beta-1a) on hospitalized patients.  

The painkiller aspirin will be evaluated as a possible treatment for Covid-19 in one of Britain’s biggest trials, which will assess whether it might reduce the risk of blood clots in people with the disease.

Gilead Sciences Inc.’s remdesivir had little or no effect on Covid-19 patients’ length of hospital stay or chances of survival, a clinical trial by the World Health Organization (WHO) found.

The anti-malaria drug touted by U.S. President Donald Trump as a Covid-19 treatment was ineffective for patients with a mild version of the disease in a study conducted by researchers at the University of Minnesota.

The World Health Organization is discontinuing the WHO’s trials of the malaria drug hydroxychloroquine and the combination HIV drug lopinavir/ritonavir in hospitalized patients with COVID-19 after they failed to reduce mortality.

A global trial designed to test whether the anti-malaria drugs hydroxychloroquine and chloroquine can prevent infection with COVID-19 is to restart after being approved by British regulators. 

New information released by GlobalData showed that there are now more than 718 pipeline drugs associated with COVID-19.
