Trial of Dasatinib Plus Ixabepilone in 2nd or 3rd Line Metastatic Breast Cancer

Completed · Phase 1/Phase 2

Conditions studied: Metastatic Breast Cancer

In brief

The primary objective for the Phase I portion of the study is to determine the maximum tolerated dose (MTD) and dose limiting toxicities (DLTs) and for the Phase II portion of the study is to evaluate progression free survival (PFS). Secondary objectives are response rate, clinical benefit rate, and overall toxicity.

You may qualify if…

• A patient must meet each of the following criteria to be considered eligible for inclusion in this study:
• Patient has the ability to understand and the willingness to sign a written informed consent including form according to institutional guidelines.
• Patient has histologically-proven breast cancer.
• Patient has locally recurrent or metastatic disease, measurable or non- measurable by RECIST criteria.
• Patient has HER2-negative disease or disease that is refractory to HER2- directed therapy.
• Patient is female or male ≥ 18 years of age.
• Patient has(ECOG)performance status of ≤ 2.
• Patient must have received at least 1 but no more than 2 prior chemotherapy regimens for locally recurrent or metastatic disease. Patients may have received neoadjuvant and/or adjuvant chemotherapy. These prior regimens can not have included ixabepilone or dasatinib. A line of chemotherapy will be defined as one or more agents used continuously or discontinuously (i.e., allowing a break or chemo holiday) without the addition of a new agent. Hormonal therapy will not be considered a line of therapy.
• Prior chemotherapy must have been completed at least 3 weeks prior to study treatment start (6 weeks for nitrosoureas and mitomycin), and the patient must have recovered from all associated toxicities (except for alopecia and neuropathy grade 1 according to CTCAE, v3.0 classification).
• Radiation therapy, immunotherapy, biologic therapy, and hormonal/endocrine therapy must have been completed at least 2 weeks prior to study treatment start. Any major surgery must have been completed at least 4 weeks prior to study treatment start.
• Patient has adequate organ, metabolic and bone marrow function as follows:
• Total bilirubin ≤ 1.0 × institutional ULN
• AST, ALT ≤ 2.5 × institutional ULN
• Serum sodium, potassium, calcium, magnesium, and phosphate ≥ institutional LLN. (Hypokalemia or hypomagnesemia must be corrected prior to dasatinib administration.)
• Serum creatinine < 1.5 × institutional ULN
• Hematologic function: - ANC ≥ 1500/mm3. -Platelet count ≥ 100,000/mm3. - Hemoglobin ≥ 10.0 g/dL
• PT and PTT < 1.5 x institutional ULN
• Ability to take oral medication (dasatinib must be swallowed whole).
• Concomitant medications:
• Patient agrees to discontinue St John's Wort at least 5 days prior to starting dasatinib therapy and while receiving dasatinib therapy.
• Patient agrees that IV bisphosphonates will be withheld for the first 8 weeks of dasatinib therapy due to risk of hypocalcemia.
• The use of CYP3A4 inducers, inhibitors, and substrates; medications that prolong QT interval; antacids; H2 blockers and proton pump inhibitors; and medications that inhibit platelet function and anticoagulation should be avoided during dasatinib therapy. These are restricted therapies that are permitted with caution when medically indicated.
• Women of childbearing potential must have a negative serum or urine pregnancy test prior to the start of study treatment.
• Patients of reproductive potential must agree to use and utilize an adequate method of contraception throughout treatment and for at least 4 weeks after study treatment is stopped.

You may not qualify if…

• A patient who meets any of the following criteria will be considered not eligible for inclusion in this study:
• Patient has had prior treatment with ixabepilone, dasatinib, or both.
• Patient has had more than 2 prior lines of chemotherapy for locally recurrent or metastatic breast cancer. A line of chemotherapy will be defined as one or more agents used continuously or discontinuously (i.e., allowing a break or chemo holiday) without the addition of a new agent. Hormonal therapy will not be considered a line of therapy.
• Patient has received a cumulative dose of > 360 mg/m2 of doxorubicin or > 600 mg/m2 of epirubicin.
• Prior radiation must not have included ≥ 30% of major bone marrow containing areas (pelvis, lumbar spine).
• Patients with CTC grade 2 or greater neuropathy (motor or sensory) at study entry.
• Patient has evidence CNS or brain metastases, unless CNS or brain metastases have been treated and stable for > 3 months.
• Patient has psychiatric illness or social situation that would limit or prohibit compliance with study requirements.
• Patient has an inability to take oral medication or inability to absorb oral medication.
• Patient has had any invasive cancer other than the one being treated in this study within 3 years with the exception of surgically cured nonmelanoma skin cancer; in situ carcinoma of the cervix; in situ carcinoma of the breast.
• Patient is receiving concurrent cancer therapy (chemotherapy, radiation therapy, immunotherapy, biologic therapy, or hormonal therapy for cancer).
• Patient has other serious medical conditions as judged by the Principal Investigator.
• Patient has a concurrent medical condition which may increase the risk of toxicity.
• Patient has a pleural or pericardial effusion of any grade.
• Patient has cardiac symptoms including any of the following:
• Uncontrolled angina, congestive heart failure or myocardial infarction within 6 months of study entry.
• Diagnosed congenital long QT syndrome.
• Any history of clinically significant ventricular arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or Torsades de pointes).
• Prolonged QTc on pre-entry ECG (> 450 msec).
• Hypokalemia or hypomagnesemia if it cannot be corrected prior to dasatinib administration.
• Patient has a history of significant bleeding disorder unrelated to cancer, including:
• Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease).
• Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor VIII antibodies).
• Ongoing or recent (≤ 3 months) significant GI bleeding.
• Patient is taking any of the following concomitant medications at study entry:
