A Study of E7389 in Advanced/Metastatic Breast Cancer Patients

Completed · Phase 2

Conditions studied: Breast Neoplasms

In brief

The purpose of this study is to determine if E7389 is a safe and effective treatment for advanced/metastatic breast cancer.

Key facts

Study ID: NCT00097721
Run by: Eisai Inc.
People needed: 104
Starts: 2004-09-01
Expected to finish: 2006-11-01
Last updated by the study team: 2013-04-22

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

Female patients with histologically or cytologically confirmed carcinoma of the breast
Patients with advanced/metastatic disease that is not amenable to curative therapy (either surgery or radiation therapy)
Patients must have measurable disease by the RECIST criteria, defined as at least one lesion that can be accurately measured in at least one diameter (at least 10 mm in longest diameter (LD) by spiral computer tomography (CT) scan, or at least 20 mm by standard techniques; If the only measurable lesion is a lymph node, it must measure at least 20 mm in LD. If a single lesion is identified as the target lesion, a cytological or histological confirmation of breast carcinoma is required.
Patients must have had prior treatment with an anthracycline and a taxane (either sequential or in combination) and may have had prior treatment with other agents as well.
Patients must have progressed within six months of the last dose of chemotherapy, or experienced disease progression while receiving chemotherapy for advanced/metastatic disease.
Resolution of all chemotherapy or radiation-related toxicities to less than grade 1 severity
Age ≥ 18 years
Eastern Cooperative Oncology Group (ECOG) Performance Status (APPENDIX 4) of 0 or 1
Life expectancy of ≥ 3 months
Adequate renal function as evidenced by serum creatinine ≤ 1.5 mg/dL or calculated creatinine clearance ≥ 50 mL/minute (min) per the Cockcroft and Gault formula
Adequate bone marrow function as evidenced by absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/L, hemoglobin ≥ 10.0 g/dL (a hemoglobin <10.0 g/dL would be acceptable if it can be corrected by growth factor or transfusion), and platelet count ≥ 100 x 10\^9/L
Adequate liver function as evidenced by bilirubin ≤ 1.5 mg/dL and alkaline phosphatase, alanine transaminase (ALT), and aspartate transaminase (AST) ≤ 3 times the upper limits of normal (ULN) (in the case of liver metastases ≤ 5 x ULN)
Patients willing and able to complete the FACT-B questionnaire, Analgesic Diary, Pain VAS, and the tumor-related symptomatic assessment
Patients willing and able to comply with the study protocol for the duration of the study
A sample from the diagnostic biopsy (paraffin block) must be available
Written informed consent prior to any study-specific screening procedures with the understanding that the patient may withdraw consent at any time without prejudice

You may not qualify if…

Patients who have received chemotherapy, radiation, hormonal therapy, or Herceptin within 2 weeks of E7389 treatment start
Radiation therapy encompassing > 10% of marrow
Failure to recover from any chemotherapy related or other therapy related toxicity at study entry that is deemed to be clinically significant by the study investigator
Prior treatment with Mitomycin C or nitrosoureas
Prior high dose chemotherapy with hematopoietic stem cell rescue in the past two years
Pulmonary lymphangitic involvement that results in pulmonary dysfunction requiring active treatment, including the use of oxygen
Active symptomatic brain metastasis; Patients with central Nervous System (CNS) metastasis are considered eligible if they have completed local therapy and discontinued from corticosteroids for at least two weeks before starting treatment with E7389
Patients with meningeal carcinomatosis
Patients who require therapeutic anti-coagulant therapy with Warfarin or related compounds; Mini dose warfarin for catheter related thrombosis prophylaxis is permitted
Women who are pregnant or breast-feeding; Women of childbearing potential with either a positive pregnancy test at Screening or no pregnancy test. Women of childbearing potential unless (1) surgically sterile or (2) using adequate measures of contraception in the opinion of the Investigator. Postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.
Severe /uncontrolled intercurrent illness/infection
Significant cardiovascular impairment (history of congestive heart failure > NYHA grade II, unstable angina or myocardial infarction within the past six months, or serious cardiac arrhythmia)
Patients with organ allografts
Patients with known positive HIV status
Patients who have had a prior malignancy, other than carcinoma in situ of the cervix, or non-melanoma skin cancer, unless the prior malignancy was diagnosed and definitively treated ≥ 5 years previously with no subsequent evidence of recurrence
Patients with pre-existing neuropathy > Grade 1
Patients with a hypersensitivity to halichondrin B and/or halichondrin B chemical derivative
Patients who participated in a prior E7389 clinical trial
Patients with other significant disease or disorders that, in the Investigator's opinion, would exclude the patient from the study
