The QT interval is the time between the start of the Q wave and the end of the T wave in the cardiac electrical cycle. The corrected QTc is the QT interval corrected for heart rate. Prolongation of the QTc was identified as clinically meaningful at the investigator's discretion.

Mean Change in QTc From Time-matched Baseline Assessed Using Fridericia's Correction Formula (QTcF) by Study Day and Time Point

The QT interval is the time between the start of the Q wave and the end of the T wave in the cardiac electrical cycle. The QTc is the QT interval corrected for heart rate. The QTcF=QT/RR\^1/3, where RR=RR interval in seconds. Baseline=predose. Mean change in QTc interval from baseline to time t=QTc interval at time t minus QTc interval at baseline.

Time frame: Predose Day 1 (Baseline) to end of Cycle 1 (28 days)

Population: Those who met all study criteria and did not require interrupted cetuximab infusion on Day (D)1 or 22; miss an ECG timepoint at baseline, D1, or D22; stop/modify dose of a scheduled drug that prolongs QT/QTc interval, receive other cancer therapy, begin a prohibited drug, or require cetuximab dose reduction before D29; withdraw consent before D23.
