| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Primary | Disease-Free Survival (DFS) at Month 36 Post-Randomization: Main Study | DFS defined as time from randomization to earliest documentation of breast cancer relapse or death from any cause. DFS at Month 36 post-randomization was defined as probability of participants alive and disease-free at 36 months after the randomization. Participants withdrawn from the study for any reason in the absence of relapse were censored at the date they were last seen. Relapse was categorized as follows: loco-regional: ipsilateral breast or axillary nodal relapse; distant: distant relapse, including supraclavicular nodes; second primary breast cancer: contralateral breast cancer, excluding ductal carcinoma in situ. | Baseline up to Month 36 | No |
| Secondary | Overall Survival (OS) at Month 36 Post-Randomization: Main Study | OS was defined as the duration from randomization to death (due to any cause). OS at Month 36 post-randomization was defined as probability of participants' survival at 36 months after the randomization. For participants who were alive, OS was censored at the last available assessment. Probability of OS at Month 36 post-randomization was reported using Kaplan-Meier estimates at Month 36 post-randomization based on 120-month follow-up data. | Baseline up to Month 120 | No |
| Secondary | Number of Events of Second Breast Cancer in Contralateral Breast: Main Study | Number of events of second primary breast cancer in contralateral breast (excluding ductal carcinoma in situ) were reported. | Baseline up to Month 120 | No |
| Secondary | Percent Change From Baseline in Lumbar Spine and Proximal Femur (Total Hip) Bone Mineral Density (BMD) at 6, 12, 24 Months On-treatment and 24 Months Post-treatment: Bone Metabolism Sub-study | BMD measurements for Lumbar spine (LS) and Proximal Femur (Total Hip [TH]) were performed using dual energy X-ray absorptiometry (DXA) for participants who entered the bone-metabolism sub-study. 'N' (number of participants analyzed) signifies those participants who were evaluable for this outcome measure and 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 6, 12, 24 months after randomization (on-treatment), 24 months post-treatment | Yes |
| Secondary | Percent Change From Baseline in Femoral Neck and Femoral Wards Bone Mineral Density (BMD) at 6, 12 and 24 Months On-treatment and 24 Months Post-treatment: Bone Metabolism Sub-study | BMD measurements for femoral neck (FN) and femoral wards (FW) were performed using dual energy X-ray absorptiometry (DXA) for participants who entered the bone-metabolism sub-study. 'N' (number of participants analyzed) signifies those participants who were evaluable for this outcome measure and 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 6, 12, 24 months after randomization (on-treatment), 24 months post-treatment | Yes |
| Secondary | Change From Baseline in Lumbar Spine and Proximal Femur (Total Hip) Bone Mineral Density (BMD) T-scores at 6, 12 and 24 Months On-treatment and 24 Months Post-treatment: Bone Metabolism Sub-study | BMD measurements for Lumbar spine (LS) and Proximal Femur (Total Hip [TH]) were performed using dual energy X-ray absorptiometry (DXA) for participants who entered the bone-metabolism sub-study. Results were scored as T-score. T-score indicated how many standard deviations higher or lower participant's value was when compared to the young normal reference mean. Using the World Health Organization (WHO) criteria for osteoporosis, a T-score of greater than or equal to (>=)-1.0 was classified as normal, a T-score of greater than -2.5 to less than -1.0 as osteopenic, and a T-score less than or equal to (<=)-2.5 as osteoporotic. Here 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 6, 12, 24 months after randomization (on-treatment), 24 months post-treatment | Yes |
| Secondary | Percentage of Bone Specific Alkaline Phosphatase (BAP) Serum Concentration Relative to Baseline: Bone Metabolism Sub-study | Bone specific alkaline phosphatase (BAP) serum concentration analyzed using enzyme immuno assay (EIA) at post-baseline time points was expressed as percentage of baseline BAP serum concentration. 'N' (number of participants analyzed) signifies those participants who were evaluable for this measure and 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 3, 6, 9, 12, 18, 24, 30 months after randomization (on-treatment), 36 months after randomization (end of treatment), 12, 24 months post-treatment | Yes |
| Secondary | Percentage of C-Terminal Telopeptide (CTX) Serum Concentration Relative to Baseline: Bone Metabolism Sub-study | C-terminal telopeptide (CTX) serum concentration analyzed using competitive enzyme-linked immunosorbent assay (ELISA) at post-baseline time points was expressed as percentage of baseline CTX serum concentration. 'N' (number of participants analyzed) signifies those participants who were evaluable for this measure and 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 3, 6, 9, 12, 18, 24, 30 months after randomization (on-treatment), 36 months after randomization (end of treatment), 12, 24 months post-treatment | Yes |
| Secondary | Percentage of Osteocalcin (OC) and Procollagen T1 C-Peptide (PICP) Serum Concentration Relative to Baseline: Bone Metabolism Sub-study | Osteocalcin (OC) serum concentration analyzed using ELISA and procollagen T1 c-peptide (PICP) serum concentration analyzed using sandwich EIA at post-baseline time points was expressed as percentage of baseline OC serum concentration and baseline PICP serum concentration, respectively. 'N' (number of participants analyzed) signifies those participants who were evaluable for this measure and 'n' signifies those participants who were evaluable for this measure at given time points, for each group respectively. | Baseline, 3, 6, 9, 12, 18, 24, 30 months after randomization (on-treatment), 36 months after randomization (end of treatment), 12, 24 months post-treatment | Yes |
| Secondary | Percentage of Deoxy-pyridinoline (DPD) Urine Concentration Relative to Baseline: Bone Metabolism Sub-study | Deoxy-pyridinoline (DPD) urine concentration (adjusted for urinary creatinine) analyzed using competitive EIA at post-baseline time points was expressed as percentage of baseline DPD urine concentration. 'N' (number of participants analyzed) signifies those participants who were evaluable for this measure and 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 3, 6, 9, 12, 18, 24, 30 months after randomization (on-treatment), 36 months after randomization (end of treatment), 12, 24 months post-treatment | Yes |
| Secondary | Percentage of N-telopeptide of Type 1 Collagen (NTX) Urine Concentration Relative to Baseline: Bone Metabolism Sub-study | N-telopeptide of Type 1 collagen (NTX) urine concentration (adjusted for urinary creatinine) analyzed using competitive inhibition EIA at post-baseline time points was expressed as percentage of baseline NTX urine concentration. 'N' (number of participants analyzed) signifies those participants who were evaluable for this measure and 'n' signifies those participants who were evaluable for this measure at given time points for each group, respectively. | Baseline, 3, 6, 9, 12, 18, 24, 30 months after randomization (on-treatment), 36 months after randomization (end of treatment), 12, 24 months post-treatment | No |
| Secondary | Number of Participants With Fracture: Bone Metabolism Sub-study | Baseline up to 24 months post-treatment | Yes | |
| Secondary | Change From Baseline in Treatment Outcome Index (TOI) at 3, 6, 9, 12, 18, 24, 30, 36, 48 and 60 Months: QoL Sub-study | The TOI was defined as the sum of 23 items based on following Functional Assessment of Cancer Therapy - Breast version [FACT-B] subscales: Physical well-being (7 items), Functional well-being (7 items), Breast cancer subscale (9 items). Each item was scaled from 0='Not at all' to 4='Very much'. Total TOI score ranged from 0 to 92, where higher TOI score indicated better health-related quality of life (QoL). A change of five points in the TOI scores was considered clinically meaningful.
