Thank you.
Dr. Fowler, my second question relates to the Solidarity trial. Could you describe which particular drugs are being tried—antivirals, hydroxychloroquine—or what they might be?
You made reference to the fact that some trials have been done, although not in very large numbers, and they were discontinued too soon. How is the Solidarity trial going to be different? Maybe you could elaborate on the numbers you're looking at for each of the medications that will be tried. Will the assignment of the particular medication to the patient be randomized? Will there be a placebo—in other words, no treatment? Could you give us a description of how that is all going to work?
