Trial Outcomes & Findings for Paclitaxel With Trastuzumab and Lapatinib in HER2-Positive Early Stage Breast Cancer (NCT NCT01827163)

NCT ID: NCT01827163

Last Updated: 2019-12-18

Results Overview

The primary objective of this trial is to determine the feasibility of this regimen in patients with node-negative HER-2/neu overexpressed /amplified breast cancer with a tumor size of \< 3 cm. The regimen is considered feasible if patients are able to complete the paclitaxel, trastuzumab, and lapatinib (THL) portion of the regimen without a dose delay or reduction or grade 3 or greater QTc prolongation.

Measure
Paclitaxel With Trastuzumab and Lapatinib
Paclitaxel (T) at 175 mg/m2 q 2 weeks x 4 with filgrastim/pegfilgrastim + trastuzumab (H) + daily oral lapatinib (L), followed by trastuzumab q 3 weeks x 15 doses + daily oral lapatinib (HL). Pegfilgrastim 6mg will be given subcutaneously (SQ) on day # 2 of each paclitaxel administration. Filgrastim may be used in lieu of pegfilgrastim at physician's discretion. Trastuzumab will be administered weekly (4 mg/kg bolus followed by 2 mg/kg weekly) starting with paclitaxel treatment cycle # 1. After 4 cycles of paclitaxel, pts will receive trastuzumab on a q 3 weeks x 15 doses (to complete about one year). The q 3 week trastuzumab may be started from 1-3 weeks after the last dose of paclitaxel. A total of 15 infusions of trastuzumab will be given q 3 weeks after the completion of paclitaxel during the HL phase. Lapatinib will be given orally at 1000 mg daily, starting with paclitaxel during the THL phase \& continued for the remaining year during the HL phase for about a year. Paclitaxel
