Design outcomes

Primary

MeasureTime frameDescription
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)From the first dose of Aromasin through the end of the study for an average of 5.6 monthsAll AEs reported after start of administration of Aromasin were considered as TEAEs and summarized.

Secondary

MeasureTime frameDescription
Time-to-Progression (Early Breast Cancer)At the end of the study, average of 5.6 monthsTime-to-Progression was defined as the duration from the date of first administration of Aromasin to the date of recurrence or contralateral breast cancer.
Percentage of Participants Without Recurrence/Metastasis (Early Breast Cancer)At the end of the study, average of 5.6 months.The antitumor efficacy for early breast cancer was measured by recurrence/metastasis status (Yes or No) of the participant at the end of the study. The investigator recorded the final evaluation date and the information of tumor recurrence or metastasis (Yes or No) in each participant's case report form (CRF).
Percentage of Participants by Overall Tumor Response Assessed Using Response Evaluation Criteria in Solid Tumors (RECIST) (Advanced Breast Cancer)At the end of the study, average of 5.6 monthsThe antitumor efficacy for advanced breast cancer was measured by objective tumor assessments according to the RECIST of uni-dimensional evaluation. Complete response (CR) was defined as disappearance of all target and non-target lesions, and no new lesions. Partial response (PR) was defined as disappearance of all target lesions, a persistence of ≥1 non-target lesions, no new lesions; or a ≥30% decrease in the sum of the longest dimensions of the target lesions, no unequivocal progression of existing non-target lesions, no new lesions. Stable disease (SD) was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease (PD), no unequivocal progression of existing non-target lesions, and no new lesions. PD was defined as a ≥20% increase in the sum of the longest dimensions of the target lesions; or unequivocal progression of existing non-target lesions, or the appearance of ≥1 new lesions.

Recruitment details

Participants were enrolled between June 2010 and June 2014 from 25 Korean health care centers.

Participants by arm

ArmCount
Aromasin
Participants were included if they had early breast cancer for adjuvant hormonal therapy or advanced breast cancer for second-line hormonal therapy after anti-estrogen therapy and were prescribed Aromasin for the first time. Aromasin was administered as part of routine care. The use and dosage recommendations for Aromasin were based on the approved local product document. Any adjustments were made solely according to medical and therapeutic necessity.

Outcome results

Primary

Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs)

All AEs reported after start of administration of Aromasin were considered as TEAEs and summarized.

Time frame: From the first dose of Aromasin through the end of the study for an average of 5.6 months

Population: Safety Analysis Set: included participants who received Aromasin at least once and were evaluated upon its related safety endpoints at least once.

Percentage of Participants by Overall Tumor Response Assessed Using Response Evaluation Criteria in Solid Tumors (RECIST) (Advanced Breast Cancer)

The antitumor efficacy for advanced breast cancer was measured by objective tumor assessments according to the RECIST of uni-dimensional evaluation. Complete response (CR) was defined as disappearance of all target and non-target lesions, and no new lesions. Partial response (PR) was defined as disappearance of all target lesions, a persistence of ≥1 non-target lesions, no new lesions; or a ≥30% decrease in the sum of the longest dimensions of the target lesions, no unequivocal progression of existing non-target lesions, no new lesions.

The antitumor efficacy for early breast cancer was measured by recurrence/metastasis status (Yes or No) of the participant at the end of the study. The investigator recorded the final evaluation date and the information of tumor recurrence or metastasis (Yes or No) in each participant's case report form (CRF).

Time frame: At the end of the study, average of 5.6 months.

Population: Efficacy Analysis Set: included all participants who received Aromasin for at least 4 weeks in treatment of breast cancer and had efficacy data available.

Time-to-Progression (Early Breast Cancer)

Time-to-Progression was defined as the duration from the date of first administration of Aromasin to the date of recurrence or contralateral breast cancer.

Time frame: At the end of the study, average of 5.6 months

Population: This outcome was planned to be analyzed in participants with early breast cancer in the efficacy analysis set. However, the analysis was not performed because the data of time-to-progression was not captured in the CRF.
