LPT 111111- A Single-arm, Multicenter Phase II Study to Evaluate The Combination of Weekly Nanoparticle Albumin Bound Paclitaxel (Nab-Paclitaxel or ABRAXANE®) and Lapatinib (TYKERB®) in Women With No More Than One Prior Treatment for ErbB2 Overexpressing Metastatic Breast Cancer

Detailed Summary

This was an open-label, single-arm, multi-center, Phase II study to determine the activity of nab-paclitaxel plus lapatinib in the first and second-line setting in women with ErbB2 overexpressing metastatic breast cancer (MBC). Sixty subjects were to be enrolled in the study. Subjects were to receive nab-paclitaxel (100 mg/m2 intravenously once weekly for 3 weeks, followed by a rest week in a 4-week cycle) plus lapatinib (1000 mg once daily). Subjects were to receive treatment until disease progression or withdrawal from the study. The primary objective of this study was to evaluate overall tumor response rate of lapatinib in combination with nab-paclitaxel administered in women with ErbB2 overexpressing MBC who received no chemotherapeutic regimen in the metastatic setting. Secondary objectives included progression-free survival, overall survival, duration of response, time to response and time to progression and safety. Safety and efficacy assessments were to be performed at 8 and 12 week intervals, and at the end of treatment. Subject: Metastatic Breast Cancer, ErbB2, First-line therapy, Lapatinib, Nab-paclitaxel
