CLTR5001: Trial Design and Methods

This unit of study will focus on the strengths and weaknesses of different clinical study designs. Designs considered will include cohort (retrospective and prospective), cross-sectional, case-control and randomized controlled designs. The different phases of clinical trial designs in the development of therapies will also be examined including phase I (first in man), phase II/pilot and phase III comparative designs. Extension and adaptation of randomized designs will also be covered including cluster and factorial designs and adaptive pilot studies. Students will gain the skills necessary to choose between these designs for best practice. Types of outcomes (continuous, categorical, time-to-event) will be discussed. Methods of allocating participants to interventions (randomization), as well blinding and allocation concealment will be covered together with aspects of protocol development. On completion of this unit, the student will be familiar with the differences between study types and study designs, as well as the principles and practice of randomisation. It is also expected that the candidate will be able to develop stratified randomisation schemes for their own studies.

  • LO2. understand basic statistical concepts of a trial design, such as sample size calculations and randomisation
  • LO3. understand the basic principles of protocol design and the key aspects that go into it
  • LO4. understand the different study designs (observational and experimental), the advantages and disadvantages of each, and when they are appropriate to use
  • LO5. understand the different types of study outcomes
  • LO6. understand how outcomes relate to study design
  • LO7. understand basic principles for sample size calculations
  • LO8. understand outcomes which are specific to oncology studies
