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

5. listopadu 2015 aktualizováno: Genentech, Inc.

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.

Časové okno: 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.

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.

Časové okno: Baseline, Cycle 1 Day 8 and Cycle 2 Day 1
Triplicate 12-lead 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 Bazette's formula (QTcB = QT divided by square root of RR). Trastuzumab steady state was defined as the average of the 2 ECG measurements collected on Cycle 1 Day 8 and Cycle 2 Day 1 after the trastuzumab infusion.
Baseline, Cycle 1 Day 8 and Cycle 2 Day 1

For each postbaseline timepoint, a participant's corresponding baseline measure was subtracted from his or her average of the triplicate ECG measure to create a "baseline-adjusted" corresponding ECG measure for each participant at each postbaseline timepoint.
Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)
Baseline-adjusted Heart Rate
Časové okno: Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)
For each postbaseline timepoint, a participant's corresponding baseline heart rate was subtracted from his or her average of the triplicate heart rate to create a "baseline-adjusted" corresponding heart rate for each participant at each postbaseline timepoint.
Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)
Number of Participants Within Each Absolute QTc Interval Category
Časové okno: Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)
Triplicate 12-lead 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) and by Bazette's formula (QTcB = QT divided by square root of RR). Participants with maximum QTc less than or equal to (<=) 450 msec, greater than (>) 450 to <=470 msec, >470 to <= 500 msec, or >500 msec were reported.
Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)

Triplicate 12-lead 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) and by Bazette's formula (QTcB = QT divided by square root of RR). Participants with maximum increase from baseline of =>30msec, 30 to <60 msec (borderline) and >=60 msec (prolonged) were summarized.
Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)

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.
Baseline, Cycle 1 Day 2 (30 minutes postdose), Cycle 1 Day 8 (15 minutes predose), Cycle 1 Day 8 (30 minutes postdose), Cycle 2 Day 1 (15 minutes predose), and Cycle 2 Day 1 (30 minutes postdose)

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.

As per planned analysis, separate population pharmacokinetic analysis results are not available for the current study as this analysis is based on pooled data from multiple studies.
