Treatment With Pazopanib for Neoadjuvant Breast Cancer

Neoplasms, Breast Clinical Trial

Official title: A Phase II Clinical Trial of Four Cycles of Doxorubicin and Cyclophosphamide Followed by Weekly Paclitaxel Given Concurrently With Pazopanib as Neoadjuvant Therapy Followed by Postoperative Pazopanib for Women With Locally Advanced Breast Cancer

Status Completed

Clinical Trial Summary

The purpose of this study is to determine whether the treatment of a doxorubicin in combination with cyclophosphamide followed by a combination of pazopanib in combination with paclitaxel prior to surgery results in a pathological complete response in females with breast cancer.

Clinical Trial Description

This is a phase II non-randomized, multi-center study aimed to evaluate the efficacy and safety of the combination of pazopanib and paclitaxel following treatment with cyclophosphamide and doxorubicin for the treatment of neoadjuvant breast cancer.

Patients will receive standard doses of AC every 21 days for 4 cycles. This will be followed by weekly paclitaxel 80 mg/m2 IV on Days 1, 8, and 15 every 28 days for 4 cycles given concurrently with pazopanib 800 mg PO daily starting with the first paclitaxel dose and continuing until 7 days before surgery. Clinical complete response rate will be determined by tumor assessments performed by palpation at two time points: following AC (before paclitaxel/pazopanib begins) and 2-4 weeks following the last dose of paclitaxel (before surgery). Following recovery from preoperative therapy, patients will undergo the clinically-indicated surgery. Pazopanib will resume 4-6 weeks after surgery and continue daily for 6 months of postoperative pazopanib therapy. ;
