Morphology
phase + III + clinical + trial
The phrase is compositionally built from its parts: 'phase' (stage) + 'III' (three) + 'clinical trial' (patient-based testing), so a B1 learner who knows the constituent words can infer it refers to the third stage of medical testing. Although full regulatory or scale-specific details are technical, the core meaning is directly derivable from the components and follows common cross-linguistic staging conventions.
Etymology
Phase III clinical trial names the third big test of a new treatment in people. Think of phase as a stage and III as the third stage, and a clinical trial as a test in patients, so a phase III trial is the large final test where many patients try the treatment to make sure it works and to watch for side effects before health officials approve it.
