Phase III is the final major testing stage for new medicines or treatments before they can be approved for public use. It involves testing the treatment on a large group of people (usually thousands) to confirm it works, monitor side effects, and compare it to existing treatments. Think of it like a final dress rehearsal before a Broadway show opens to the public - everything needs to be thoroughly checked to ensure safety and effectiveness. This stage is crucial because it's usually the last step before a company can ask for government approval to sell the medicine.
