"Fuzzy, I could be misinterpreting but, you had seemed to take it as a bad sign that the ph 2 covid trial has not been halted early. Just my impression but it seems to me that in general only ph 3 trials are stopped early for efficacy"

Yes, i was looking at it as a "bad sign"  but was unaware of your point "generally only ph 3 trials are stopped early" so glad thats the case & thank you kindly for correcting that!!
