Summary

Targeted therapy is typically developed along with important biomarkers that regulate cell signaling, malignant transformation, and proliferation. To discriminate prognostic and predictive biomarkers, this chapter creates four 2 x 2 contingency tables, in which each cell represents the response rate of that specific group. It also describes the randomized discontinuation design (RDD), adaptive signature design, and adaptive threshold design. The adaptive signature design can achieve three goals: to identify the subset of patients who are most likely to benefit from the new agent; to maintain a properly powered test of an overall treatment effect at the end of the trial using all randomized patients; and to test the treatment effect for the subset of sensitive patients selected from the patients enrolled in stage 2. Finally, the chapter discusses two different procedures for hypothesis testing.
