An effect of ivacaftor was observed by day 15 of treatment . A substantial treatment effect was maintained throughout the scholarly study, with a noticeable change in the % of predicted FEV1 from baseline through week 48 that was 10.5 %age points better with ivacaftor than with placebo . The distribution of individual adjustments from baseline through week 24 showed that nearly 75 percent of the subjects who were treated with ivacaftor got a mean improvement of 5 %age points or even more . The change in the % of predicted FEV1 was analyzed within predefined subgroups also, including subgroups defined relating to baseline FEV1, age, and sex.

All events were reported by the enrolling site to the central coordinating middle and were verified by coordinating-center staff with the source medical records submitted. Sometimes, an assessment of source documents led to the identification of unreported occasions or the withdrawal of submitted events. A central review committee examined electrocardiographic findings without understanding of the participant’s randomized assignment. Statistical Analysis The CPORT-E trial was designed as a noninferiority trial. Based on previous studies, the 6-week all-cause mortality price was estimated at 0.8 percent11,12 and the rate of major adverse cardiac events at 9 months was estimated at 12.0 percent.13-16 Noninferiority margins for the difference in event rates were set at 0.4 %age points for the 6-week end point and 1.8 %age points for the 9-month end stage.All events were reported by the enrolling site to the central coordinating middle and were verified by coordinating-center staff with the source medical records submitted.
