Just interesting. I have no predictions about the results. Especially, since a definitive answer is likely to come from this large study. Results expected this summer which is unheard of for a study like this.
It is of note that Remdesivir is an IV medication and Gilead Sciences has no plans for making a pill that could be used as prophylaxis or early treatment.
I would like to add this caution. Nisser mentioned prolongation of the QT interval. This risk is greater when azithromycin (Z-Pak) is added. From the FDA: “Use with caution ……during concomitant administration with QT interval prolonging drugs such as azithromycin and some other antibacterial drugs.”
The article is behind a Medscape paywall (or signup at least) so a link will not be helpful:
[i]"In perhaps the fastest-moving, large prophylaxis trial, researchers at Duke University are leading a $50 million collaboration across hundreds of American health care systems, which will test 15,000 volunteers. Half the health care workers will take hydroxychloroquine, and half a placebo. Other drugs could be added to the study if they prove promising for preventing or lessening infection, says Adrian Hernandez, the trial’s principle investigator.
The trial is being launched by PCORnet®, the National Patient-Centered Clinical Research Network, a network of health care systems that have come together over the last few years to plan and conduct research trials. Although the collaboration predates COVID-19 by nearly five years, this is precisely the kind of situation it was designed to address, says Hernandez, adding that he hopes the network will soon be able to test COVID-19 vaccine candidates as well."[/i]
Lopinavir and Ritonavir prophylaxis also being tested in France:
“In France, researchers are running a trial with 1,200 health care workers to test prophylactic use of hydroxychloroquine or a combination of two HIV drugs, Lopinavir and Ritonavir, which failed as a treatment in people with severe COVID-19 infections but may work as prevention. It is expected to take 6 months.”
