What this phase means
Phase 2/3: earlier tests looked promising enough to expand. This stage asks, in a larger group, whether the treatment really works and is safe enough to seek approval.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
