Morphology
Each constituent directly contributes to the overall meaning: 'phase' = stage, 'II' = two, 'clinical' = medical/patient-related, and 'trial' = testing. A B1 learner who knows these words can reasonably infer this refers to the second stage of medical testing to evaluate effectiveness and monitor side effects; numbering of phases is a common, cross-linguistically transparent convention.
Etymology
Phase II clinical trial comes from the idea of testing a new treatment in numbered steps: phase means a step and II is the second step. After a small first test, this second step gives the treatment to more people to see if it really works and to watch for 'side effects', so the phrase means a larger test of 'effectiveness' and safety.
