E.5 End points |
E.5.1 | Primary end point(s) |
Objective tumor response rate (ORR) based on blinded central radiological review of all tumor evaluations is the primary end point of the study.
The study is planned according to the fixed-sample design for proving efficacy. The aim is to show that therapy with mFOLFOX6 for colorectal cancer in combination with regorafenib improves the response rate observed for the standard therapy alone. The response rate for the standard therapy is assumed to be 40%.
The design specifications are as follows:
one-sided type I error level = 10% ,
power = 90% (type II error rate = 10%), and
"response rate for standard therapy" p0= 0.40 (null hypothesis),
where the one-sided type I error level is the probability of rejecting the null hypothesis if the true response rate is less than or equal to 40% and 1-power is the probability of rejecting the alternative hypothesis if the true response rate is greater 40%.
For the power calculation it is assumed, that under the alternative hypothesis the expected response rate for combination therapy may be 60%, ie, p1 = 0.6.
These specifications result in the total sample size of 41 patients.
The final analysis of efficacy will be performed after the last subject included into the
treatment phase has been treated for at least 6 months. If this last subject discontinues from
the study, for any reason, before being treated for 6 months then the preceding subject will be
treated and followed for 6 months before the final analysis of efficacy will be performed.
