If they had twenty people enrolled...

Very unlikely we would hear about it. Even the PI might not know about the readout until the study is finished.

I think City also said...

It's really impossible to predict how long it will take. There are so many factors that could affect the rate of enrollment.

If they kept it...

My guess is it's more likely to be August. They will probably wait until the study is completed before doing the stats, but it should all be done by September, I think. But difficult to judge.

Sorry I can' be more informative!
