Therapy for Locally Advanced Breast Cancer Using Doxil, Paclitaxel, and Cyclophosphamide With Avastin

Phase II Trial of Primary Systemic Therapy for Locally Advanced Breast Cancer Using Sequential Doxil, Paclitaxel, and Cyclophosphamide With Concurrent Avastin

This study will evaluate the rate of pathological complete response (pCR) to the sequential therapy of Doxil, paclitaxel, and cyclophosphamide with concurrent Avastin for patients with locally advanced invasive (T2,T3, Nany, M0) breast carcinoma. Also, the study will evaluate the clinical and subclinical cardiotoxic effect(s) of this regimen, assess how feasible and safe the study is. Survival without any progression of disease will also be calculated.

A regimen of chemotherapy will be given to replicate the high rate of pCR seen with conventional chemotherapy in patients with locally advanced breast cancer. Doxil will substitute the normally given doxorubicin. It is expected that the low effect or minimal effect of Doxil on cardiac function will minimize any additional risk of cardiotoxicity from Avastin. It is expected that clinical and subclinical rates of cardiotoxicity will be very low at the total doses to be given in this clinical trial.

Study Overview

• Status: Completed
• Conditions: Invasive Breast Cancer
• Intervention / Treatment: Drug: Doxil, Paclitaxel, Cyclophosphamide, Avastin

Detailed Description

In this trial, an attempt will be made to replicate the high rate of pathological complete response seen after conventional chemotherapy in patients with locally advanced breast cancer, using a regimen in which Doxil is substituted for conventional doxorubicin. We expect that the low or minimal effect on cardiac function produced by Doxil will minimize any additional risk of cardiotoxicity from Avastin. We will also measure left ventricular ejection fractions before and after treatment to see if the substantial rate of subclinical cardiotoxicity reported by Swain et al 5 and Perez et al 7 can be avoided. The reported rates of cardiotoxicity after treatment with relatively high doses of Doxil are substantially lower than those of doxorubicin; few data are available to estimate the rate of cardiotoxicity of Doxil in patients treated with only about 100 mg/m2 total accumulated dose, the dose to be utilized here. The drug has been used in a few patients in the primary systemic therapy setting, with no reported clinical cardiotoxicity.

The expectation is that clinical and subclinical rates of cardiotoxicity will be very low or negligible at the total doses to be used here.

• Patients must have a 2-d echocardiogram indicating an ejection fraction of > 50% within 42 days prior to first dose of study drug. The method used at baseline must be used for later monitoring.
• No distant metastases on bone scan and on CT scans of chest and abdomen (no metastasis on optional PET scan is an acceptable alternative; if PET scan is done for any reason it must show no evidence of distant metastasis). Baseline PET scan is recommended but not required for all patients.

• Known CNS metastasis, except for treated brain metastasis. Treated brain metastases are defined as having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and brain imaging (MRI or CT) during the screening period. Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy (WBRT), radiosurgery (RS; Gamma Knife, LINAC, or equivalent) or a combination as deemed appropriate by the treating physician. Patients with CNS metastases treated by neurosurgical resection or brain biopsy performed within 3 months prior to Day 1 will be excluded.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of Achievement of Pathological Complete Response (pCR)	Results of the pathologic evaluation of the surgical specimen(s) from operation (segmental or total mastectomy) will be used to report the overall complete pathological response rate. Criteria used were those described by Kaufmann et al, Journal of Clinical Oncology 2003; 21(13):2600-2608. The definition of pCR used from this source was absence of invasive cancer in both resected breast tissue and in resected axillary nodes.	After completion of at least 8 of the 9 chemotherapy doses and operation.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participant With Clinical or Subclinical Cardiotoxicity	Left ventricular ejection fraction (LVEF) measurements and clinical examination at baseline and at end of therapy will be used.	Prior to treatment and at completion of chemotherapy
Calculate Progression Free Survival	Progression free survival (PFS) will be defined as survival without local recurrence of breast cancer and without the development of distant metastasis. Death from any cause will be included as an event. The Kaplan-Meier nonparametric method will be used to estimate progression free survival.	5 years
Assess Toxicities of Regimen Including Hand Foot Syndrome	patients who receive any treatment drugs will be included for toxicity evaluation. Adverse events will be summarized with frequencies and proportions of study participants exhibiting adverse events. The severity of adverse events (none, mild, moderate, severe) and their relationship to the product will be presented.	Baseline, every 2 weeks during treatment, and at completion of therapy. Every 3 weeks during postoperative Avastin
