About this study

Official title: A Phase II Study of Neoadjuvant Lapatinib Plus Chemotherapy (Sequential FEC75 and Paclitaxel) in Women With Inflammatory Breast Cancer Whose Tumors Overexpress ErbB2 (Her2/Neu)

The goal of this clinical research study is to learn how well lapatinib taken alone, followed by taking lapatinib with paclitaxel, and then taking lapatinib with 5-fluorouracil, epirubicin, and cyclophosphamide (FEC75) works to help to control Inflammatory Breast Cancer (IBC). The safety of this drug combination will also be studied.

Read the detailed description

The Study Drugs:

Lapatinib is designed to prevent or slow down the growth of cancer cells by blocking proteins inside the cancer cell, called the Her2/neu receptor and the epidermal growth factor (EGFR).

Cyclophosphamide, paclitaxel, and 5-fluorouracil are designed to block cancer cells from dividing, which may slow or stop their growth and their ability to spread throughout the body. This may cause the cancer cells to die.

Epirubicin is designed to attach to DNA (the genetic material of cells) which may slow or stop their growth and cause them to die.

Study Drug Administration:

On Weeks 1-24 you will take lapatinib every day by mouth with water (about 8 ounces). It should be taken at least 1 hour before or at least 2 hours after eating. It is important that you take the study drug at about the same time every day. You should not eat pamelo fruit, grapefruit, star fruit, pawpaw, and/or drink their juices while on study.

If you forget to take a dose of the study drug, you should take the missed dose as soon as you remember, unless it has been more than 12 hours. If it has been more than 12 hours, do not take the missed dose. Instead, take the next dose as scheduled the next day. If you vomit after taking the study drug, wait until the next day to take your next dose.

The study drug should be stored at room temperature and out of direct sunlight. The study drug should be kept away from children. About every 3 weeks, you will need to bring back your empty or partially used bottle of study drug as instructed by your doctor.

On Weeks 3-12, you will receive paclitaxel through a needle in your vein 1 time a week. The infusion will take about 1 hour. You will continue to take lapatinib every day.

On Weeks 13-24, you will receive 5-fluorouracil, epirubicin, and cyclophosphamide 1 time every 21 day study cycle. You will receive 4 cycles. Each 5-fluorouracil infusion will take about 3-5 minutes, each epirubicin infusion will take about 5-10 minutes, and the cyclophosphamide infusion will take about 45-60 minutes. You will continue to take lapatinib every day during Weeks 13-24.

If you experience intolerable side effects, the study doctor may give you drugs to help with this side effect or change your dose of study drug.

Study Visits:

On Day 1 of Week 1, the following tests and procedures will be performed:

  • You will have a physical exam, including measurement of your vital signs and weight.
  • You will be asked about any drugs that you may be taking.
  • You will have a performance status evaluation.

Every 3 weeks while taking combination chemotherapy and study drug, the following tests and procedures will be performed:

  • You will have a physical exam, including measurement of your vital signs and weight.
  • You will be asked about any changes in your health and any drugs that you may be taking.
  • You will have a performance status evaluation.
  • Your medical history will be recorded.
  • Blood (about 3 tablespoons) will be drawn for routine tests.

At Week 6, you will have a CT scan, MRI, and/or a bone scan to check the status of the disease.

At the end of the chemotherapy treatment, the disease will be measured by physical exam, chest CT scan and sonogram to check the status of the disease. If the disease has gotten worse, you will be taken off study. If the disease has gotten worse, you will be taken off study. Your doctor will discuss your next step of treatment options.

Surgery:

At the end of the chemotherapy period, if the disease has responded well to the drugs, you will have surgery to remove the breast tumor. You will sign a separate consent form for the surgery. Either at the end-of-treatment visit at week 24 after you are done with chemotherapy, or before the surgery, the following tests will be performed:

  • You will have a complete physical exam, including measurement of your vital signs and weight.
  • You will have a performance status evaluation.
  • You will be asked about any drugs you may be taking.
  • Blood (about 3 tablespoons) will be drawn for routine tests
  • You will have an ECG.
  • You will have a multiple gated acquisition scan (MUGA) or echocardiogram to check your hearts health.
  • You will have a CT scan, MRI, and/or a bone scan to check the status of the disease.
  • You will have a tissue biopsy to check the status of the disease.

Length of Study:

You may continue to receive the study drugs for up to 24 weeks. You will be taken off study early if the disease gets worse or intolerable side effects occur.

Long-Term Follow-Up:

Once you are off study, you will have follow-up visits at 3 and 6 months after surgery. At these visits, you will have a MUGA or ECHO performed.

You will have additional visits every 4 months for Years 2 and 3, and then every 6 months for Years 4 and 5. At these visits, blood (about 3 tablespoons) will be drawn for routine tests.

This is an investigational study. Lapatinib is FDA approved and commercially available when taken in combination with capecitabine for another type of breast cancer. Using Lapatinib in inflammatory breast cancer is investigational.

5-fluorouracil, epirubicin, cyclophosphamide, and paclitaxel are all FDA approved and commercially available for treating breast cancer. The combination of these drugs is not currently FDA approved for the treatment of IBC. At this time, this drug combination is only being used in research.

Up to 60 patients will take part in this study. All will be enrolled at M. D. Anderson.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Rate of Pathologic Complete Response (pCR) Following Neoadjuvant Chemotherapy

    Pathologic complete response (pCR) rate defined as number of participants out of total that had no residual invasive disease (malignant cells) in the breast or axillary lymph nodes as assessed at the time of surgery following completion of all protocol specified neoadjuvant chemotherapy, which is approximately 26 weeks following the start of neoadjuvant chemotherapy.

    Measured: Assessed at time of surgery following completion neoadjuvant chemotherapy (approximately 26 weeks)

Secondary outcomes (1)

  1. Number of Participants With pCR After Completion of All Protocol Specified Therapy & Surgery (Surgical Population)

    Pathologic complete response [pCR or RCB Class 0] defined as no residual invasive disease (malignant cells) in the breast or axillary lymph nodes as assessed at the time of surgery following completion of all protocol specified neoadjuvant chemotherapy, which is approximately 26 weeks following the start of neoadjuvant chemotherapy and surgery. the residual cancer burden (RCB) was estimated from routine pathologic sections of the primary breast tumor site and the regional lymph nodes. The calculated RCB index value is categorized as one of four RCB classes, RCB-0 to RCB-III where RCB-0 is best prognosis (no residual disease) to RCB-III a worst prognosis. The RCB score for participants was assessed following completion of all protocol specified therapy, 4 cycles of lapatinib and paclitaxel followed by 4 cycles of lapatinib plus FEC75 and surgery.

    Measured: Following definitive surgery at completion of neoadjuvant chemotherapy (following approximately 26 treatment weeks)
