Morphology
The meaning is directly compositional: 'preclinical' (before clinical/human testing) combined with 'trial' (a testing process) yields a trial conducted prior to human clinical studies. The prefix 'pre-' and the noun 'trial' follow a common, cross-linguistic pattern, so a B1 learner who knows the constituents can readily infer this meaning.
Etymology
The term preclinical trial comes from its parts: pre means 'before', clinical is about tests with people, and trial is a 'test'. So a preclinical trial is a 'test' done before any testing on people, often in a lab or on animals.
