Eribulin Treatment as 1st-line or 2nd-line Chemotherapy for HER2-negative Hormone-resistant Inoperable or Recurrent Metastatic Breast Cancer (E-SPEC)

June 10, 2021 updated by: Translational Research Center for Medical Innovation, Kobe, Hyogo, Japan

Prospective Observational Study to Explore the Efficacy of Eribulin as 1st-line or 2nd-line Chemotherapy in Patients With HER2-negative Hormone-resistant Inoperable or Recurrent Metastatic Breast Cancer

This is a observational study in a real-world setting, not requiring determining a dosage regimen, dose reduction criteria, rest period criteria and withdrawal criteria. The purpose of the study is to investigate the efficacy of eribulin as the first or second line chemotherapy to prolong overall survival and to explore factors affecting the survival in patients with HER2-negative hormone-resistant inoperable or recurrent metastatic breast cancer who scheduled to receive the first or second line chemotherapy in clinical practice in Japan. The total duration of the study will be a maximum of 5 years, consisting of 2-year enrollment period and 3-year observational period; the duration of patient participation will be 3 years. All patients will receive adequate treatment for breast cancer which selected by the primary physician after enrollment using the Japanese Breast Cancer Society Clinical Practice Guideline of Breast Cancer and the National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology. Investigators at the investigational sites will enter patient data into an electronic data capture (EDC) system up to the third chemotherapy in the study. The end of the study is defined as the time the last patient completes observational period. Patients will primarily be assessed by overall survival (OS) of the first line chemotherapy.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

Description

Inclusion Criteria:

  1. Female patients with histologically or cytologically confirmed breast cancer.
  2. Patients with inoperable or recurrent metastatic breast cancer regardless of the metastatic site and number, excluding symptomatic central nervous system metastases.
  3. Patients with HER2-negative disease confirmed as ISH negative or IHC 0, 1+ or 2+ (Those with IHC 2+ are eligible, if the additional ISH test results are negative. Those are ineligible who are with any positive results of estrogen receptor or progesterone receptor test on primary and recurrent lesion).
  4. Patients who are resistant to hormone therapy.
  5. Patients with indication for the first or second line chemotherapy in HER2-negative hormone-resistant inoperable or recurrent metastatic breast cancer who are scheduled to receive the chemotherapy.
  6. Patients with the Eastern Cooperative Oncology Group (ECOG) performance status score 0-3 at the time of enrollment.
  7. Patients with adequate bone marrow and major organ function judged by the primary physician.
  8. Patients who have signed written informed consent to participate in this study.

Exclusion Criteria:

  1. Patients with symptomatic metastasis in the central nervous system.
  2. Patients with a previous history of hypersensitivity to any component of drugs which will be administered in the treatment.
  3. Patients who are considered to be inappropriate for the study participation by the primary physician.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
