It is interesting to speculate some more. Sinclair tells above about the preventive treatment of the healthcare workers by chloroquine, which has been the main usage of it in malaria prevention. To my mind comes immediately that PBT2 could well be a good drug for this purpose if it works in killing the virus. Chloroquine is not a very safe drug but in the prevention of malaria, it was used only once a week. In Corona IMO once a week is not enough IMO but 300mg PBT2 / day could well be enough and most likely would not cause any side-effects as was the case in the phase 2 study. So ATHE needs first the in vitro study, then the randomized, placebo-controlled phase 2 study in Corona population and perhaps at the same time a placebo-controlled, randomized study in the healthcare population. In this wild epidemy, the risk of developing PBT2 resistant virus needs to be taken.
My guess is that the in vitro phase will be ready soon, study plans are under development and patent applications are perhaps already done. I am checking Clinical trials every day if there are any iron chelators listed. Yesterday there were 143 different Corona studies listed and today 15 more. No prophylaxis studies yet. Corona is a hot topic today and Dr. Sinclair is one among those interested in that.
