Preclinical and clinical
Preclinical work usually involves laboratory systems or animals. Clinical research involves people under a defined protocol, oversight and eligibility criteria.
Early clinical findings can change as trials grow larger, last longer or use a different comparison group.
Approval is specific
Approval applies to a defined medicine, formulation, manufacturer, indication and jurisdiction. Research interest or a registered trial is not regulatory approval.
