  Purpose

In this study, patients with metastatic HER2-negative breast cancer will receive treatment with ixabepilone and sorafenib until disease progression or unacceptable toxicity occurs. The Phase I portion of this study will determine the maximum tolerated doses (MTDs) of sorafenib and ixabepilone that may be used in combination for first- or second-line treatment of MBC. The MTDs identified in the Phase I portion of the study will be used in the Phase II portion which will evaluate the efficacy and safety of the combination of sorafenib and ixabepilone in patients who have received at least one prior chemotherapy treatment in either the adjuvant or neoadjuvant setting or following one prior MBC chemotherapy in MBC patients who had not received prior adjuvant or neoadjuvant breast cancer chemotherapy. This will be one of the initial trials investigating the use of this treatment combination for MBC.

This trial will be conducted under the leadership of the Sarah Cannon Research Institute (SCRI) Oncology Research Consortium, a community-based, multi-center, clinical trial organization.

This Phase I portion will be a dose-escalation evaluation of the first 6-24 patients to determine the maximum doses of sorafenib and ixabepilone that can be used in combination. The dosing level may be influenced by treatment-related toxicities seen throughout cycles of treatment for 3 cycles for a total of 9 weeks.

Dose Level 1: 200 mg of Sorafenib by mouth twice a day for a 3 week cycle. Ixabepilone 40mg/m2 IV on day 1 of a 21 day cycle.

Dose Level 2: 400 mg of Sorafenib by mouth twice a day for a 3 week cycle. Ixabepilone 40mg/m2 IV on day 1 of a 21 day cycle.

Dose Level -1: 200 mg of Sorafenib by mouth once a day for a 3 week cycle. Ixabepilone 40mg/m2 IV on day 1 of a 21 day cycle.

Dose Level -2: 200 mg of Sorafenib by mouth once a day for a 3 week cycle. Ixabepilone 32mg/m2 IV on day 1 of a 21 day cycle.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Age ≥ 18 years.
  2. Histologically or cytologically confirmed breast cancer diagnosis with metastatic disease. Patients without pathologic or cytologic confirmation of metastatic disease should have unequivocal evidence of metastasis.
  3. Measurable disease, as per RECIST criteria (Therasse et al. 2000). Measurable disease cannot be previously irradiated unless progression was documented. Measurable disease is defined as: at least one lesion that can be accurately measured in at least one dimension [longest diameter to be recorded] as >20 mm with conventional techniques, or as >10 mm with spiral computed tomography (CT) scan. Disease must be measurable, i.e., bone-only disease or evaluable-only disease is not eligible.
  4. Patients with brain metastasis may participate if they:

    • have undergone appropriate treatment,
    • are at least 1 month post-treatment,
    • have no neurologic symptoms,
    • are not on steroids,
    • have a follow-up magnetic resonance imaging (MRI) scan that demonstrates no residual active lesions, and
    • have no new untreated lesions.

      5 The following prior therapies are allowed:

    • No prior chemotherapy in the metastatic setting. However, patients must have received prior adjuvant or neo-adjuvant chemotherapy.
    • Prior radiation therapy in either the metastatic or early-stage setting, as long as <25% of the bone marrow has been treated. Radiation therapy must be completed at least 14 days prior to study registration, and all radiation-related toxicities must be resolved to ≤ grade 1 before the patient is eligible for study inclusion.
    • Any number of hormonal therapies in the neo-adjuvant, adjuvant, or metastatic setting is allowed. Patients must discontinue hormonal therapy at least 1 week prior to starting study treatment.
    • Prior bevacizumab administered >4 weeks before initiation of study treatment is allowed.

      6 HER2-negative status. Documentation of HER2 results must be available at the time of study enrollment. HER2-negative is defined as:

    • Immunohistochemical (IHC) 0 or IHC 1+ OR
    • Fluorescence in situ hybridization (FISH) negative (defined by FISH ratio <2.2) OR
    • Silver in-situ hybridization (SISH) negative (defined by SISH ratio <2.2). Patients with an IHC 2+ will need to be validated as HER2-negative by FISH.

      7 An Eastern Cooperative Oncology Group (ECOG) performance status of < or = to 2.

8. Normal bone marrow function as defined by:

  • absolute neutrophil count (ANC) >1,500/μL;
  • platelets >100,000/μL;
  • hemoglobin >9 g/dL. 9 Normal hepatic function as defined by:
  • total bilirubin within normal institutional limits;
  • aspartate aminotransferase (AST) and alanine aminotransferase (ALT) <2.5 × the institutional upper limit of normal (ULN) for patients without liver metastasis; <5.0 × ULN for patients with liver metastasis.

    10. Normal renal function as defined by creatinine <1.5 × ULN.

    11. Left ventricular ejection fraction (LVEF) within institutional limits of normal.

    12. International normalized ratio (INR) <1.5 or a prothrombin time/partial thromboplastin time (PT/PTT) within normal limits. Patients receiving anti-coagulation treatment with an agent such as warfarin or heparin may be allowed to participate. The INR should be measured prior to initiation of sorafenib, and for patients on warfarin, INR should be monitored at least weekly following initiation of protocol treatment, until the INR is stable and therapeutic.

    13. Life expectancy of >6 months.

    14. For women of childbearing potential, negative serum pregnancy test within 7 days prior to starting treatment.

    15. For women of childbearing potential and men, agreement to use a method of contraception that is acceptable to their physician from time of first signing the informed consent and for the study duration. Men should use adequate birth control for at least three months after the last administration of sorafenib. If a woman becomes pregnant or suspects she is pregnant while participating in this study, she must agree to inform her treating physician immediately. As applicable, patients must agree to discontinue breast-feeding until at least 3 weeks after their last dose of study drug.

    16. Recovery to < grade 1 toxicity due to prior therapy.

    17. Ability to understand and willingness to sign a written informed consent document.
