Showing the boundaries for analyzing the sequential trial using the Triangular test with the following parameters (p0 = 0.75, pa = 0.9, α = 0.05, β = 0.05, and n = 10). The vertical line at n = 30 indicates that, for the PK component of the trial, a minimum of 30 patients per arm will be recruited, unless the lower boundary has been crossed before then.Back to article page
