What is being measured

The primary outcome is the main question the study is designed to answer.

Change From Baseline in Corrected QT Interval Using Fridericia's Correction (QTcF) at Trastuzumab Steady State
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.

Secondary outcomes (10)

Change From Baseline in Corrected QT Interval Using Bazett's Correction (QTcB) at Trastuzumab Steady State
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.
Measured: Baseline, Cycle 1 Day 8 and Cycle 2 Day 1
Baseline-adjusted QTcF, QTcB, PR Interval, and QRS Duration
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.
Measured: 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
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.
Measured: 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
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.
Measured: 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 With Increase From Baseline in QTc Interval
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.
Measured: 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 With New Abnormal U Waves on ECG
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.
Measured: 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 With New Abnormal T Waves on ECG
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.
Measured: 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 With Abnormal Changes in PR Interval
Criteria for abnormal changes in PR interval were defined as: =>25 percentage (%) change from baseline, an absolute value >200 msec, or >=25% change from baseline and an absolute value >200 msec.
Measured: 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 With Abnormal Changes in QRS Interval
Criteria for abnormal changes in QRS interval were defined as: >=25% change from baseline, an absolute value >110 msec, or >=25% change from baseline and an absolute value >110 msec.
Measured: 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)
Population Pharmacokinetics of Trastuzumab
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.
Measured: 15 (±15) minutes prior to the start of the trastuzumab infusion, and 30 (±15) minutes after the end of the infusion on Cycle 1 Day 2, Cycle 1 Day 8, Cycle 2 Day 1, and Cycle 3 Day 1

What is this clinical trial studying?

A Phase 1 study testing carboplatin, docetaxel and trastuzumab in people with Solid Cancers, run by Genentech, Inc. at 20 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Dec 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 20 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Dec 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Corrected QT Interval Using Fridericia's Correction (QTcF) at Trastuzumab Steady State (time frame: Baseline, Cycle 1 Day 8 and Cycle 2 Day 1). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00927589.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Dec 2015.
