Reporting Groups
  Description
GW572016 (Lapatinib) GW572016 was administered at a dose of 1500 mg orally daily on an outpatient basis. Patients were advised to take GW572016 on an empty stomach (either 1 hour before or 1 hour after meals). GW572016 was administered continuously until disease progression or unacceptable toxicities. For the purposes of protocol evaluations, a cycle was defined as 28 days.
