Donald Trump's touted 'game-changer' malaria drug for Coronavirus fails another test

The deadly virus outbreak has created havoc around the world infecting more than 3.8 million people worldwide

The malaria treatment that was constantly pushed by the US President Donald Trump as a game-changer in the fight against the coronavirus or COVID-19 has again failed to prove a benefit in patients hospitalised with the disease caused by the novel virus, as per a study released on Thursday.

The study which was published in the New England Journal of Medicine had a few limitations. The doctors confirmed that the use of hydroxycholoquine did not decrease the breathing assistance need of patients nor did it reduce the risk of death.

"We didn't see any association between getting this medicine and the chance of dying or being intubated," lead researcher Dr Neil Schluger told Reuters in a telephone interview. "The patients who got the drug didn't seem to do any better." Among patients given hydroxychloroquine, 32.3 percent ended up needing a ventilator or dying, compared with 14.9 percent of patients who were not given the drug.

But doctors were more likely to give hydroxychloroquine to sicker patients, so researchers at New York-Presbyterian Hospital and Columbia University Irving Medical Center adjusted the rates to account for that. They concluded that the drug may not have hurt patients, but it clearly did not help.

Decades-old hydroxychloroquine, which is also used to treat lupus and rheumatoid arthritis, also showed no benefit when combined with the antibiotic azithromycin, Schluger's team reported. Azithromycin alone also showed no benefit. Last month, doctors at the US Department of Veterans Affairs reported that hydroxychloroquine did not help COVID-19 patients and might pose a higher risk of death.

That analysis of medical records showed a death rate of 28 percent when the drug was given in addition to standard treatments, compared to 11 percent with standard care alone. In the latest study, 811 patients got hydroxychloroquine and 565 did not.

Because they were not randomly assigned to receive hydroxychloroquine or a placebo, "the study should not be taken to rule out either benefit or harm" for the drug, researchers said. Randomized trials, the gold standard for tests of new therapies, should continue, they added. But for now, "the guidance in our hospital has changed so we don't recommend giving hydroxychloroquine to hospitalized patients," said Dr Schluger, chief of the division of pulmonary, allergy and critical care medicine at Irving.

Smaller studies, including one done in China, had suggested hydroxychloroquine might be useful, "but these were tiny studies and not of good quality. People seized on them because patients were dying," he said. There are currently no approved treatments for COVID-19, although Gilead Sciences Inc's experimental antiviral drug remdesivir last week receive emergency use authorization from US regulators.
