Eksperymentalny: Subjects with cancer

In Part 1 of the study, subjects will be randomized to one of four sequences. All subjects will receive oral or intravenous (IV) midazolam on Days 1, 3, 9 and 11 as per assigned randomization scheme. Starting on Day 4 through Day 11, subjects will receive a daily dose of 1500 milligrams (mg) of oral lapatinib.

In Part 2, which will begin on Day 12, the subjects will be required to take 1500 mg of lapatinib daily until removed from the study for disease progression, adverse events, withdrawal of consent, or transfer to another lapatinib study.

Subjects will receive midazolam by oral or IV route on Days 1, 3, 9 and 11. Oral midazolam was supplied as 3 mg tablets; IV midazolam was supplied as 1 milligram per milliliter (mg/L) sterile solution.
Inne nazwy:
  • GW572016 oral tablets
Subjects will receive 1500 mg lapatinib by oral route once daily from Day 4.
