Study Summary

The double blind part of the study is being conducted to compare the efficacy and safety of pazopanib in combination with lapatinib with that of lapatinib alone in subjects with inflammatory breast cancer whose tumors overexpress the ErbB2 protein. There is also an Open-label pazopanib arm to this study designed to test whether pazopanib given alone and lapatinib given alone would be safe and effective to treat patients with inflammatory breast cancer.

Primary Outcome

RECIST-based response assessment was done at Weeks (Wks) 4 and 8 and every 8 weeks thereafter. Cutaneous disease assessment was done at Wk 4 and every 4 weeks thereafter. OR was evaluated when the skin and RECIST assessments coincided. Per RECIST, CR is the disappearance of all target and non-target lesions; PR is at least a 30 percent (%) decrease in the sum of the longest diameter (LD) of target lesions, taking as a reference the baseline sum LD. Cutaneous disease contained non-measurable and
