64. Over 1 year, a study is conducted to assess the antileukemic activity of a new tyrosine kinase
inhibitor in patients with chronic myeloid leukemia in blast crisis. All patients enrolled in the study are informed that they would be treated with the tyrosine kinase inhibitor. They are assigned to successive dose cohorts of 300 to 1000 mg/day of the drug. Six to eight patients are assigned to each dose. Treatment efficacy is
determined based on the results of complete blood counts and bone marrow assessments conducted regularly throughout the study. This study is best described as which of the following?
(A) Case-control study
(B) Crossover study
© Open-labeled clinical trial
(D) Randomized clinical trial
(E) Single-blind, rando
