Paclitaxel Followed by FEC Versus Paclitaxel and RAD001 Followed by FEC In Women With Breast Cancer

September 12, 2016 updated by: M.D. Anderson Cancer Center

Open Label Randomized Clinical Trial of Standard Neoadjuvant Chemotherapy (Paclitaxel Followed by FEC) Versus the Combination of Paclitaxel and RAD001 Followed by FEC in Women With Triple Receptor-Negative Breast Cancer (CRAD001C24101)

The goal of this clinical research is to learn if RAD001 given in combination with chemotherapy will turn off the signaling pathway (a chain of information that tells cancer cells to grow quickly) and make the chemotherapies given on this study more effective.

Primary Objective

· To determine if the addition of an mTOR inhibitor to standard neoadjuvant chemotherapy in patients with triple receptor-negative breast cancer causes molecular changes (inhibition/activation) of the PI3K/PTEN/AKT pathway.

Secondary Objectives

  • To evaluate pathologic complete response (pCR) rates for each treatment group.
  • To evaluate the relationship between pCR and the molecular changes (inhibition/activation) of the PI13K/PTEN/AKT pathway in each treatment group.
  • To evaluate overall response rates (ORR) for each treatment group.
  • To assess the toxicity of both regimens and to evaluate the relationship of toxicities with PI3K/PTEN/AKT pathway status.

Study Overview

Detailed Description

RAD001 is a new drug that was designed to block proteins that are important in the development and growth of cancer. It may also stop the growth of new blood vessels that help tumor growth, resulting in cell death.

Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have a complete physical exam. Blood (about 6 tablespoons) will be drawn for routine tests and to test for the amount of fat in the blood. You will have a chest x-ray, bone scan and a 2-D echocardiogram (a test to evaluate the pumping function of the heart). You will have a computed tomography (CT) scan of the chest and abdomen (stomach area). Women who are able to have children must have a negative blood (about 1 tablespoon) pregnancy test.

You will have a mammogram and an ultrasound of the breast and armpit to record tumor size. As part of this study, you will have a fine needle biopsy of the breast tumor to test for the signaling pathway. You will receive a separate consent form for the mammogram, ultrasound, and biopsy and these procedures will be discussed with you in more detail. The fine needle biopsy is a procedure that would not be performed if you were not on this study.

If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to one of two treatment groups. You will have an equal chance of being assigned to either group.

If you are assigned to Group 1, you will receive paclitaxel once a week through a needle in your vein over 1 hour. You will have a total of 12 treatments. Before each treatment, you may also receive drugs to help prevent or reduce your risk of side effects from paclitaxel.

If you are assigned to Group 2, you will receive paclitaxel and RAD001. You will receive paclitaxel once a week through a needle in your vein over 1 hour. You will have a total of 12 treatments. Before each treatment, you may also receive drugs to help prevent or reduce your risk of side effects from paclitaxel. You will take RAD001, by mouth, on each day you receive paclitaxel. You should take RAD001 on an empty stomach or after a light meal. Pills will not be taken out of their package until the staff is ready for you to take them, since they can be damaged by light or humidity.

Participants in both groups will have blood (about 2 tablespoons) drawn for routine tests before each weekly dose of chemotherapy.

You will have a second fine needle biopsy 2 days after starting treatment. This will be done to check to see if the signaling pathway has been affected.

After your 12 weeks of treatment with paclitaxel or paclitaxel and RAD001, you will have an ultrasound and if tumor is visible, a fine needle biopsy to check to see if the signaling pathway has been affected.

After the 12 week treatment with either paclitaxel or paclitaxel and RAD001, you will begin treatment with 5-fluorouracil, epirubicin, and cyclophosphamide. This drug combination is called FEC. You will receive FEC through needle in your vein (over 1 hour) once every 3 weeks. You will have 4 treatments (12 weeks total). Before each treatment, you may also receive drugs to help prevent or reduce your risk of side effects from FEC.

Once you have finished treatment with FEC, you will have a mammogram and ultrasound to check the status of the disease. This mammogram and ultrasound will also be used by the doctor to decide whether to remove all or part of the breast and/or nearby lymph nodes during surgery.

You will then have surgery to remove all or part of the breast that has the tumor. If there are signs that the lymph nodes in the armpit contain cancer, these lymph nodes will also be removed. You will receive a separate consent form for these procedures and your doctor will discuss them in more detail. If available, a portion of left over tumor tissue will be collected to check to see if the signaling pathway has been affected.

You will be considered "off study" once you have had surgery. You will be taken off study early if the disease gets worse or intolerable side effects occur.

This is an investigational study. Paclitaxel, 5-fluorouracil, cyclophosphamide, and epirubicin are all FDA approved and commercially available. RAD001 is not FDA approved or commercially available. It has been authorized for use in research only. Up to 50 patients will take part in this study. All will be enrolled at M. D. Anderson.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number Participants With Inhibition of PI3K/PTEN/AKT Pathway at 48 Hours
Time Frame: 48 hours after start of treatment
Number of participants with inhibition of the PI3K/PTEN/AKT pathway at 48 hours after the start of treatment, regardless of the status of the pathway at the time of randomization. Molecular changes (inhibition/activation) of the PI3K/PTEN/AKT pathway evaluated using reverse phase protein arrays (RPPA) where fine-needle aspirations (FNAs) from the primary breast cancer obtained pretreatment, and at 48 hours. Bioinformatics cluster analysis of arrays used to define molecular changes as inhibition or activation where pathways called 'active' with presence of 2 or more phosphorilated pathway proteins (pAKT, pmTOR, pGSK3, pS6K1, pS6), and 'inhibited' with one or none phosphorilated pathway proteins present.
48 hours after start of treatment
