A Study to Evaluate Corrected QT Interval and Drug-Drug Interaction of Trastuzumab on Carboplatin in the Presence of Docetaxel in Patients With HER2-Positive Metastatic or Locally Advanced Inoperable Cancer
A Phase 1b, Single-arm, Open-label Clinical Trial to Evaluate Corrected QT Interval and Drug-drug Interaction of Trastuzumab on Carboplatin in the Presence of Docetaxel in Patients With Metastatic Cancer
This Phase Ib, multicenter, single-arm, open-label study is designed to evaluate the effect of trastuzumab on QTcF interval and to characterize the effects of trastuzumab on carboplatin pharmacokinetics in patients with HER2-positive metastatic or locally advanced inoperable cancer.
The QT interval is a measure of time between the start of the Q wave and the end of the T wave in the heart's electrical cycle. The QTcF interval is the QT interval as calculated using Fridericia's correction; the QTcB interval is the QT interval as calculated using Bazett's correction.

Change From Baseline in Corrected QT Interval Using Fridericia's Correction (QTcF) at Trastuzumab Steady State
時間枠:Baseline, Cycle 1 Day 8 and Cycle 2 Day 1
|
Triplicate 12-lead electrocardiogram (ECG) measurements (each recording separated by approximately 2 minutes) were performed and average was calculated.
The time corresponding to beginning of depolarization to repolarization of the ventricles (QT interval) was adjusted for RR interval using QT and RR from each ECG by Fridericia's formula (QTcF = QT divided by cube root of RR).
Trastuzumab steady state was defined as the average of the 2 ECG measurements collected on Cycle 1 Day 8 (C1D8) and Cycle 2 Day 1 (C2D1) after the trastuzumab infusion.

|
The incidence of abnormal U-wave changes from baseline was determined based on centrally read ECG tracings comparing each of the three triplicate readings from the post baseline ECG time points to the baseline ECG reading.
At each time point, if at least one of the three triplicate readings was abnormal, the participant was counted as abnormal for that ECG timepoint as follows: a large U wave, inverted U wave, or T-U fusion compared with baseline was considered an abnormal significant change from baseline.

The incidence of abnormal T-wave changes from baseline was determined based on centrally read ECG tracings comparing each of the three triplicate readings from the post baseline ECG time points to the baseline ECG reading.
At each time point, if at least one of the three triplicate readings was abnormal, the participant was counted as abnormal for that ECG timepoint as follows: an inverted T, flat T, or biphasic T compared with baseline was considered an abnormal significant change from baseline.
Additionally, nonspecific T-wave changes from baseline were considered as abnormal nonsignificant changes from baseline.
T-wave changes from baseline due to ventricular conduction or left ventricular hypertrophy strain were considered not evaluable.
