    • diagnostic trials
  2. phase 1 trials
    • determine metabolism and pharm actions
    • evaluates SE associate w/ inc doses
    • gain early evidence of effectiveness
  3. Phase II trials
    • controlled CT
    • evaluates effectivesness of the drug
    • includes pt with disease or condition

    randomization between bloacks of sequential participants
  17. stratified randomization
    randomization with clusters of participants
  18. primary endpoint
    usually an efficacy measure or routine and useful measure
  19. secondary endopoint
    important but not primary purpose of the study (usually ADEs, toxicity)
  20. composite endpoints
    • -utilized when accessing efficacy for different endpoints
    • -common with illnesses with high morbidity and mortality
  21. intent to treat analysis
    includes all data from participants in the group to which they were randomized
  22. per protocol
    evaluates data of only the subjects that completed the sudy per protocol
  23. external validity
    generalization of the results
