Conditions

Interventions

DRUG

Oral lapatinib tablets or placebo tablets

Subjects administered open label lapatinib, 1500 mg to be taken orally once a day, for 12 weeks. After 12 weeks, subjects with a partial or complete response per Response Evaluation Criteria in Solid Tumors (RECIST) will continue to receive open label lapatinib (1500 mg/day orally) until disease progression. Subjects who maintain stable disease will be randomized in a 1:1 ratio to enter stage 2 of the study and receive double blind therapy of either lapatinib 1500 mg/day orally or placebo. Subjects who progress on placebo will have the option to receive lapatinib 1500 mg/day orally until further progression. Those who progress on lapatinib will be withdrawn from the study.
