Eribulin Mesylate Phase IV Clinical Trial in Korean Patients With Metastatic or Locally Advanced Breast Cancer

This clinical study is designed as an open, single group, multi-center, phase 4 clinical study to assess the safety of eribulin which is approved for the treatment of the patients in Korea with locally advanced or metastatic breast cancer who had received two to five prior chemotherapy regimens including anthracyclines and taxanes for advanced disease.

Subjects who meet the inclusion/exclusion criteria are administered of 1.4 mg/m2 of the investigational product intravenously in 2-5 min on day 1 and day 8 of every 21-day cycle. In case of the progression of disease, unacceptable toxicity, withdrawal of the consent, or judgment by investigator that the treatment needs to be stopped, the treatment of investigational product is stopped, and treatment termination assessment is performed within 30 days from the last treatment.

Treatment and study plan

eribulin mesylate

Drug

1.4 mg/m2 (as eribulin 1.23 mg/m2) day by 2-5 minutes IV on Day 1 and 8 every 21 days

Primary outcomes

Number of Participants With Any Treatment-emergent Adverse Event (TEAE) and Any Treatment-emergent Serious Adverse Event (SAE)

Time frame: mean of 3.76 months

An AE is defined as any harmful, untoward sign (including abnormal laboratory value, etc.), symptom, or disease in a participant administered investigational product that does not necessarily have a causal relationship with treatment. An SAE is defined as an AE that is life threatening or results in death, results in hospitalization (initial or prolonged), results in a disability (significant, persistent, or permanent change, impairment, damage or disruption in the participant's body function/structure, physical activities, or quality of life), results in a congenital anomaly, or requires intervention to prevent permanent impairment or damage. TEAEs are defined as those events that started on or after the date and time of administration of the first dose of study drug and those events that were present prior to the administration of the first dose of study drug and increased in severity during the study.

Secondary outcomes

Disease Control Rate (DCR)

Time frame: mean of 3.76 months

DCR is defined as the number of participants with complete response (CR), partial response (PR), and stable disease (SD). The Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 was used to assess the tumor response. Tumor response was evaluated by investigators. CR is defined as the disappearance of all extranodal target lesions. All pathological lymph nodes must have decreased to <10 millimeters (mm) in the short axis. PR is defined as at least a 30% decrease in the sum of the longest diameters (SLD) of target lesions, taking as reference the baseline sum diameters. SD is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (SLD increased by at least 20% from the smallest value on study [including baseline, if that is the smallest]. The SLD must also demonstrate an absolute increase of at least 5 mm. [Two lesions increasing from 2 mm to 3 mm, for example, does not qualify]).
