Can anyone define a CDN phase 1B trial?I am more familiar with FDA trials Phase I Testing of drug on healthy volunteers for dose-ranging Phase II Testing of drug on patients to assess efficacy and side effects Phase III Testing of drug on patients to assess efficacy, effectiveness and safety From NR.... The Phase Ib NMIBC clinical study ("Study") will be used to evaluate TLD-1433 for the primary endpoints of safety and tolerability. Wonder why they use the phrase "treated" when it looks , to me, it's more about 'testing" for safety , like a Phase 1 Trial in the US. is the first patient healthy?
