Secondary outcomes:

Duration of response

Timeframe: (assessments every 12 weeks until death for withdrawn participants and every 3 weeks for participants continuing on lapatinib)

Progression-free survival (PFS)

Timeframe: From start of treatment to disease progression/death (assessments every 12 weeks until death for withdrawn participants and every 3 weeks for participants continuing on lapatinib)
