HER2/neu positive, locally advanced or metastatic
Brief summary
This study will compare the anti-tumor efficacy of apricoxib and lapatinib/capecitabine with placebo and lapatinib/capecitabine as measured by time to disease progression and evaluate urinary PGE-M measurements or baseline COX-2 expression in tumor tissue by IHC as a surrogate selection criterion for patients who will benefit from future treatment with apricoxib.
Interventions
apricoxib: 100 mg tablets, 400 mg/day lapatinib: per package insert capecitabine: per package insert
placebo: 100 mg tablets, 400 mg/day lapatinib: per package insert capecitabine: per package insert
