No there is not always a path. Look at some of the 50+ Other covid drugs that path was stopped in phase 1 or phase 2 than look at the ones that had to change their path. Unlike the ones that failed CYDY is still standing, looking good in discussions with 3 countries. Please tell me how many failed covid-19 drugs that finished double blinded placebo trial had talks with 3 different regulatory agencies immediately following the unblinding of their data? You can be pessimistic all you want I will continue to look at the facts and draw conclusions from those.
