Hich have been 5 ms, with upper limits on the corresponding 90 CIs of ten ms. In Cycle 3, mean QTcF values for each post-infusion time points within the pertuzumab and placebo groups have been five ms. Variability of QTcF information inside the placebo group was markedly greater than that observed within the pertuzumab group. Imply values of QTcF for the 05 min and 605 min post-infusion time points were 8.41 ms (90 CI -2.58, 19.39) and -0.04 ms (90 CI -11.12, 11.04), respectively. Even though the upper limits on the 90 CIs for each time points have been ten ms, the 90 CIs also includedY = + pertuzumab + ,where Y may be the response variable (i.e., QTcF), the intercept represents the mean response, plus the slope represents the modify in imply for a unit modify in pertuzumab serum concentration. The statistical significance with the slope parameter () corresponds for the following hypothesis testing:H0 : =andH1 : = 0.Using a statistical criterion of p 0.05, this corresponds to a modify inside the objective function, defined as (-2) * loglikelihood, of three.83 units. Interindividual variability, as a random effect (an additive term), was estimated for intercept () and, if doable, slope (), as well as their correlation. Random effects were assumed to become typically distributed with imply zero and variance 2. The matrix becomes diagonal when the correlation is zero. The additive measurement error was assumed to become normally distributed with imply zero and unknown continual variance two [26].

In total, 37 female sufferers were enrolled in the substudy, of whom 20 received pertuzumab plus trastuzumab plus docetaxel and 17 received placebo plus trastuzumab plus docetaxel. The mean age was 53.1 years, along with a total of 33 sufferers (89.2 ) were 65 years of age. Substudy participants had a mean weight of 70.9 kg.Cancer Chemother Pharmacol (2013) 72:1133141 Table 1 QTcF in Cycles 1 and 3, by therapy arm Time point QTcF (ms) Placebo + trastuzumab + docetaxel n Cycle 1 30 min before infusion 15 min before infusion 05 min post-infusion 605 min post-infusion 72 h post-infusion 30 min prior to infusion 15 min before infusion 05 min post-infusion 605 min post-infusion 15 15 15 17 17 17 17 17 17 Imply SD 420.five 21.77 419.4 20.40 426.9 19.19 426.6 18.13 420.five 11.06 411.9 19.01 410.1 17.47 415.2 21.77 416.1 21.49 Median (variety) 425.7 (375.0, 466.five) 424.3 (367.7, 444.0) 425.three (391.7, 451.0) 423.three (380.0, 451.0) 418.7 (394.3, 439.0) 413.7 (374.7, 440.7) 411.0 (378.three, 452.0) 416.7 (379.0, 451.7) 415.three (375.0, 453.3) Pertuzumab + trastuzumab + docetaxel n 18 18 20 17 17 19 19 19 19 Mean SD 411.three 15.10 410.1 17.29 415.9 18.35 410.five 18.98 409 13.80 407.six 17.10 405.8 17.53 413.two 16.23 407.9 18.25 Median (range)Cycle417.7 (378.3, 432.7) 416.7 (374.7, 433.0) 419.5 (367.three, 444.three) 414.0 (374.7, 431.3) 409.7 (386.0, 431.three) 408.0 (362.3, 431.0) 408.0 (354.7, 430.0) 416.7 (374.three, 438.3) 410.7 (369.7, 436.7)QTcF QT interval, corrected for heart price making use of Fridericia’s correctionFig. 1 Summary of incidence of ECG abnormalities by cycle and time point.
