Comparing Eribulin with S1, to assess HRQoL in Her2 negative Metastatic Breast Cancer Patients: RESQ

Phase 3
Conditions
metastatic breast cancer
HER2 negative, metastatic breast cancer
Registration Number
JPRN-jRCTs011180026
Lead Sponsor
WATANABE KENICHI
Brief Summary

It is hypothesized that the eribulin-treated arm is comparable to or superior to the S1 arm in overall HRQoL as measured by EORTC QLQ-C30 Global Health Status as a first- or second-line treatment for ER2-negative metastatic breast cancer. However, non-inferiority was not demonstrated statistically. Regarding the median overall survival, the Eribulin group was 35 months compared to 27.8 months in the S1 group (HR 0.69 [95% CI 0.50-0.95]; P=0.023), which was significantly longer in the Eribulin group.

(a) At the diagnosis of breast cancer, the patient has both primary breast cancer and distant metastasis (STAGE IV).
(b) The patient has breast cancer that has worsened or recurred in association with distant metastasis after treatment (after surgery and pre- and post- operative treatment); however, local recurrence is excluded
(iii) Chemotherapy is scheduled for the treatment of metastatic breast cancer.

(xi) Written informed consent has been obtained directly from the subject

Exclusion Criteria

(i) Overexpression of human epidermal growth factor receptor 2 (Her2), or the results of in situ hybridization are positive.
(ii) Patient has received more than two chemotherapy line for metastatic disease.
(iii)Patient has received eribulin or S-1.
(iv) Patient has more than CTCAE grade 3 anxiety at enrollment.
(v) The presence of interstitial pneumonia or pulmonary fibrosis.
(vi) The presence of cardiac conduction abnormality (heart failure, ischemic heart disease)
(vii) The presence of pleural effusion, ascites or pericardial effusion requiring tubing or emergency treatment.
(viii)Patient has to receive systemic steroid treatment continuously.

(xiii) bilateral breast cancer (excluded DCIS or corresponding ER and HER2 status)
