| E.2.2 | Secondary objectives of the trial |
To assess and compare between the two treatment groups:
• Quality of Life measured using the EORTC questionnaire
• Objective Tumor Response Rate as measured using RECIST criteria
• Duration of Response
• One, Two and Three year Survival
• Tumor Related Symptom Assessments measured by pain intensity (VAS), and analgesic consumption
• Safety Parameters (adverse events, laboratory parameters, concomitant medication, and study drug exposure)
To investigate pharmacokinetic/pharmacodynamic relationships in a population pharmacokinetic study in a minimum of 200 patients in the E7389 arm

| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1. Female patients with histologically or cytologically confirmed carcinoma of the breast. Every effort should be made to ensure that paraffin embedded tissue or slides from the diagnostic biopsy or surgical specimen are available for confirmation of diagnosis.
2. Patients with locally advanced or metastatic disease who have received either one anthracycline-taxane combination chemotherapy, or two prior therapies, including an anthracycline-based regimen without a taxane, and a taxane-based regimen. The order in which the regimens were received is unimportant. The treatments may have been administered as adjuvant or neoadjuvant chemotherapy and/or for the treatment of advanced or metastatic disease.
• Regimens must have included an anthracycline (e.g. doxorubicin, epirubicin) and a taxane (e.g. paclitaxel, docetaxel) either concomitantly or sequentially
• If the treatment has been administered as adjuvant or neoadjuvant therapy (not both), the patient must have relapsed during the treatment or within one year following the last dose of the most recent treatment, and this must be documented
• If the treatment has been administered for advanced or metastatic disease, the patient must have progressed during the last treatment or within six months of the last dose of of the most recent treatment, and this must be documented
• Patients with known HER2/neu over-expressing tumors must additionally have been treated with trastuzumab in centers where this treatment is available
• Patients with known estrogen receptor-expressing tumors may have additionally been treated with estrogen-specific therapy
3. Resolution of all chemotherapy or radiation-related toxicities to Grade 1 severity or lower, except for stable sensory neuropathy ≤Grade 2 and alopecia
4. Age ≥ 18 years
5. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
6. Life expectancy of ≥ 3 months
7. Adequate renal function as evidenced by serum creatinine ≤ 2.0 mg/dL or calculated creatinine clearance ≥ 40 mL/minute (min) per the Cockcroft and Gault formula
8. Adequate bone marrow function as evidenced by absolute neutrophil count (ANC) ≥ 1.5 x 10*/L, hemoglobin ≥ 10.0 g/dL (a hemoglobin <10.0 g/dL acceptable if it is corrected by growth factor or transfusion), and platelet count ≥ 100 x 10*/L
*=9
9. Adequate liver function as evidenced by bilirubin ≤ 1.5 times the upper limits of normal (ULN) and alkaline phosphatase, alanine transaminase (ALT), and aspartate transaminase (AST) ≤ 3 x ULN (in the case of liver metastases ≤ 5 x ULN), or in case of bone metastases, liver specific alkaline phosphatase ≤ 3 x ULN
10. Patients willing and able to complete the EORTC quality of life questionnaire (QLQ-C30 with breast cancer module QLQ-BR23) and Pain VAS
11. Patients willing and able to comply with the study protocol for the duration of the study
12. Written informed consent prior to any study-specific screening procedures with the understanding that the patient may withdraw consent at any time without prejudice
|
|
| E.4 | Principal exclusion criteria |
1. Patients who have received more than two prior chemotherapy regimens for their disease, including adjuvant therapies (other therapies are allowed e.g. anti-estrogens, trastuzumb and radiotherapy)
2. Patients who have received capecitabine as a prior therapy for their disease
3. Patients who have received chemotherapy, radiation, hormonal therapy, or trastuzumab within three weeks of E7389 treatment start
4. Radiation therapy encompassing > 30% of marrow
5. Prior high dose chemotherapy with hematopoietic stem cell rescue
6. Prior treatment with mitomycin C or nitrosourea
7. Pulmonary lymphangitic involvement that results in pulmonary dysfunction requiring active treatment, including the use of oxygen
8. Patients with brain or subdural metastases are not eligible, unless they have completed local therapy and have discontinued the use of corticosteroids for this indication for at least 4 weeks before starting treatment with E7389. Any signs (e.g. radiologic) and/or symptoms of brain metastases must be stable for at least 4 weeks.
9. Patients with meningeal carcinomatosis
10. Patients who are receiving anti-coagulant therapy with warfarin or related compounds, other than for line patency, and cannot be changed to heparin-based therapy, are not eligible. If a patient is to continue on mini-dose warfarin, then the prothrombin time (PT) / international normalized ratio (INR) must be closely monitored.
11. 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. Perimenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential.
12. Severe/uncontrolled intercurrent illness/infection
13. 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)
14. Patients with organ allografts requiring immunosuppression
15. Patients with known positive HIV status
16. 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
17. Patients with pre-existing neuropathy > Grade 2
18. Patients with a hypersensitivity to halichondrin B and/or halichondrin B chemical derivative
19. Patients who participated in a prior E7389 clinical trial
20. Patients with other significant disease or disorders that, in the Investigator’s opinion, would exclude the patient from the study |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
Overall Survival is measured from the date of randomization until date of death from any cause or the last date the patient was known to be alive.
Progression-Free Survival is measured from the date of randomization to the date of recorded progression of the disease or the death of the patient from any cause. |
