Best Overall Response Rate (BORR) (Calliper)
Time frame · 24 weeks
The BORR were defined as the percentage of patients with confirmed CR or PR in the ITT population during 24 weeks pre-operative treatment period (based on the data from calliper measurement). CR (or PR) criteria are met at 2 or more time in points every 4 weeks. Per RECIST Criteria (V1.0) and assessed by Calliper: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>= 30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Best Overall Response Rate (BORR) (US)
Time frame · 24 weeks
The BORR were defined as the percentage of patients with confirmed CR or PR in the ITT population during 24 weeks pre-operative treatment period (based on the data from ultra sound (US) measurement). CR (or PR) criteria are met at 2 or more time in points every 4 weeks. Per RECIST Criteria (V1.0) and assessed by US: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>= 30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Best Overall Response Rate (BORR) (MRI/CT)
Time frame · 24 weeks
The BORR were defined as the percentage of patients with confirmed CR or PR in the ITT population during 24 weeks pre-operative treatment period(based on the data from magnetic resonance imaging (MRI) or computed tomography (CT) measurement). CR (or PR) criteria are met at either 12 weeks or 24 weeks. Per RECIST Criteria (V1.0) and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>= 30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
Bone Mineral Density (BMD) Lumbar Spine
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in Bone Mineral Density value (percentage), in all subjects who used DXA(Dual-energy X-ray absorptiometry) method throughout the study, at 24 weeks measured at lumbar spine.
Bone Mineral Density (BMD) Cervical Thighbone
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in Bone Mineral Density value (percentage), in all subjects who used DXA(Dual-energy X-ray absorptiometry) method throughout the study, at 24 weeks measured at cervical thighbone.
Bone Turnover Marker (BAP) EIA Method
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in serum Bone-Alkaline Phosphatase (BAP) at 24 weeks measured by EIA method
Bone Turnover Marker (BAP) CLEIA Method
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in serum Bone-Alkaline Phosphatase (BAP) at 24 weeks measured by CLEIA method
Bone Turnover Marker (NTX)
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in serum crosslinked N-Telopeptide of type I collagen (NTX) at 24 weeks
Serum Oestrone (E1) Concentrations
Time frame · Assessed at baseline and after 24 weeks of treatment
Ratio of serum Oestrone (E1) concentration (pg/mL) in the ITT population from baseline at 24 weeks.
Serum Oestradiol (E2) Concentrations
Time frame · Assessed at baseline and after 24 weeks of treatment
Ratio of serum Oestradiol (E2) concentration (pg/mL) in the ITT population from baseline at 24 weeks.
Oestrogen Receptor (ER) Status
Time frame · Assessed at baseline and after 24 weeks of treatment
ER status in the ITT population is categorized as Positive or Negative
Progesterone Receptor (PgR) Status
Time frame · Assessed at baseline and after 24 weeks of treatment
PgR status in the ITT population is categorized as Positive or Negative.
Human Epidermal Growth Factor Receptor 2 (HER2) Status
Time frame · Assessed at baseline and after 24 weeks of treatment
HER2 status in the ITT population is categorized as Positive or Negative
Histopathological Response Rate (HRR)
Time frame · Assessed at baseline and after 24 weeks of treatment
Number of patients in the ITT population defined as histopathological responders over the total number of patients x 100. An histopathological responder = a patient classified as Grade 1b, 2 or 3 for the histopathological response (Grade 0 = no response, 1a = mild response, 1b = moderate response, 2 = marked response or 3 = complete response)
Functional Assessment of Cancer Therapy-Breast (FACT-B)
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in Functional Assessment of Cancer Therapy-Breast (FACT-B)in the ITT population at 24 weeks. Trial Outcome Index (TOI) = the sum of the Physical Well-Being (PWB), Functional Well-Being (FWB), and Breast Cancer Scale (BCS) subscales of FACT-B. FACT-B includes 36 questions; 7 in PWB (Physical Well-Being); 7 inSWB (Social / Family Well-Being); 6 in EWB (Emotional Well-Being); 7 in FWB (Functional Well-Being); 9 in BCS (Breast Cancer Subscale). Total score of subscores or TOI is calculated from each score of question. Higher score means better and lower score means worthier. Score range; 0-28 in PWB; 0-28 in SWB; 0-24 in EWB; 0-28 in FWB; 0-36 in BCS; 0-92 in TOI.
Endocrine Subscale (ES)
Time frame · Assessed at baseline and after 24 weeks of treatment
Change from baseline in Endocrine Symptom Subscale (ES)) in the ITT population at 24 weeks. ES score = the sum of the responses to all the questions on ES, low scores reflect poor quality of life and high scores reflects better quality of life. Score range: 0-72
Anastrozole Plasma Concentrations (Cmin)
Time frame · Assessed at week 12
Trough Plasma concentrations (Cmin) of Anastrozole - only Anastrozole arm was evaluated for Trough Plasma concentrations.
