  Purpose

Primary Objectives

  • Assess ultrastructure changes in dermal myelinated nerves of patients who receive ixabepilone chemotherapy
  • Detailed characterization of peripheral neuropathy in patients who receive ixabepilone

Secondary Objectives

  • Clinical benefit rate
  • Time to progression ( TTP)
  • Toxicity
  • Exploratory studies:

    • Relation of MDR 1 and TRKA polymorphisms to evolution of ultrastructural neurologic changes observed in neurons.
    • Relation of NGF, IL8, and IL10 to the development of clinical symptoms and ultrastructural changes in neurons.

Primary Outcome Measures:
  • effect of ixabepilone on breast cancer and structure of neurons [ Time Frame: duration of study ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: November 2007
Estimated Study Completion Date: December 2010
Estimated Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: ixabepilone
    ixabepilone 40 mg/m2 Q3w over 3 hours
Detailed Description:

Eligible patient population:

  • Stage 4 breast cancer
  • Resolution from toxicity of prior therapy to ≤ CTC grade 1 ( except alopecia)
  • No limit on prior number of therapies to treat cancer
  • Adequate organ function
  • Life expectancy greater than 3 months

Treatment: ixabepilone 40 mg/m2 Q3w over 3 hours

Evaluation on Study:

I. Efficacy evaluation:

  • Baseline CT chest, abdomen and pelvis and bone scan within 4 weeks of starting therapy
  • Evaluation of disease every 2 cycles of chemotherapy
  • Ongoing toxicity evaluation using NCI CTC 3.

II. Neurological evaluation:

  • Detailed neurologic exam using Neuropathy Assessment Instrument (represents a standard neurological exam)
  • Serum NGF, IL 8,10, prior to starting therapy and prior to each cycle of ixabepilone
  • DNA for assessment of TRK A and MDR1 polymorphisms
  • Punch biopsy of skin prior to starting therapy and after every 2 cycles. Laboratory evaluation of peripheral nerve biopsies will be conducted at Rockefeller University under the direction of Dr. Carlson in Dr. Strickland's Lab.
  Eligibility

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

Inclusion Criteria

  • Ability to understand and the willingness to sign a written informed consent document.
  • Histologic or cytologic diagnosis of adenocarcinoma originating in the breast.
  • Evidence that the cancer is metastatic or locally advanced and not curable by local measures (i.e., surgery, radiation).

NOTE: There is no limit on number of prior chemotherapy regimens received.

  • Karnofsky performance status (KPS) score of 70 - 100; (Appendix 1).
  • Life expectancy of at least 12 weeks.
  • Adequate recovery of drug related toxicities from prior systemic therapy (recovery to < = Grade 1 except for Grade 2 fatigue and alopecia).
  • Adequate recovery from recent surgery and radiation therapy. At least one week must have elapsed from the time of a minor surgery and/or focal/palliative radiation therapy; at least 3 weeks for major surgery and other radiation therapy.
  • Women or Men, age > = 18 years.
  • Patients must have normal organ and marrow function as defined below:

    • Hematologic function with absolute neutrophils ≥ 1,500/mm3 and/or platelets > 125,000/mm3
    • Hepatic function with serum bilirubin less than 1.5 times the upper institutional limits of normal, ALT ≤ 2.5 times the upper institutional limits of normal (≤ 5 times the upper institutional limits of normal if documented hepatic metastases are present)
    • Renal function with serum creatinine ≤ 1.5 times the upper limit of normal
  • Women of childbearing potential (WOCBP) and men with partners who are of childbearing potential must be using an adequate method of contraception to avoid pregnancy throughout the study and for up to 4 weeks after the study in such a manner that the risk of pregnancy is minimized.

WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilization (hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or is not postmenopausal (defined as amenorrhea > = 12 consecutive months; or women on hormone replacement therapy (HRT) with documented serum follicle stimulating hormone (FSH) level > 35 mIU/mL). Even women who are using oral, implanted or injectable contraceptive hormones or mechanical products such as an intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent pregnancy or practicing abstinence or where partner is sterile (e.g., vasectomy), should be considered to be of child bearing potential.

- WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of study medication.

Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.

Exclusion Criteria

  • Patients with known and active brain and/or leptomeningeal metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
  • CTC Grade 2 or greater neuropathy (motor or sensory) at study entry.
  • Prior treatment with ixabepilone.
  • Serious intercurrent infections, or nonmalignant medical illnesses that are uncontrolled or whose control may be jeopardized by the complications of this therapy, including, but not limited to: ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
  • Known history of HIV infection.
  • Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier.
  • Patients may not be receiving any other concurrent chemotherapy, hormonal therapy, immunotherapy regimens or radiation therapy, standard or investigational.
  • History of allergic reactions attributed to compounds of similar chemical or biologic composition to ixabepilone.
  • Known prior severe hypersensitivity reactions to agents containing CremophorEL.
  • Patients may not be receiving any prohibited therapies and/or medications.
  • Pregnant and lactating women are excluded from the study because the risks to an unborn fetus or potential risks in nursing infants are unknown.
