phase 3
Final trial stage
Phase 3 typically refers to the third stage of a structured process, most commonly in pharmaceutical development where it designates large-scale clinical trials testing a drug's effectiveness and safety in hundreds or thousands of patients before regulatory approval.
The term appears in other staged frameworks—construction projects, pandemic responses, business plans—where numbering marks progression: We're entering phase 3 of the rollout.
