Outcome Measures

Primary Outcome Measures

  1. Disease-Free Survival (DFS) at Month 36 Post-Randomization: Main Study [Baseline up to Month 36]

    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 Participants withdrawn from the study for any reason in the absence of relapse were censored at the date they were last seen.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.

Secondary Outcome Measures

  1. Overall Survival (OS) at Month 36 Post-Randomization: Main Study [Baseline up to Month 120]

    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.

  2. Number of Events of Second Breast Cancer in Contralateral Breast: Main Study [Baseline up to Month 120]

Study Results

Participant Flow

Recruitment Details The publication describing study results (Coombes RC et al; N Engl J Med 350; 1119) stated that 4742 participants were enrolled in study. It was later discovered that 2 participants were randomized twice. Hence, 4740 participants were enrolled in this study.
Pre-assignment Detail Main study also included 3 sub-studies only for the purpose of tolerability assessment: endometrial status, bone metabolism and quality of life (QoL). Out of 4740 enrolled participants, data for 16 participants from a center were excluded since it was considered unreliable. Results are reported for remaining 4724 participants.
Arm/Group Title Exemestane Tamoxifen
Arm/Group Description Participants diagnosed with breast cancer who remained disease-free after previously receiving 2 to 3 years of tamoxifen 20 milligram (mg) or 30 mg tablet-in-capsule orally once daily as per standard medical practice, received exemestane (Aromasin) 25 mg tablet-in-capsule orally once daily for the remainder of 5-year period. Participants diagnosed with breast cancer who remained disease-free after previously receiving 2 to 3 years of tamoxifen 20 mg or 30 mg tablet-in-capsule orally once daily as per standard medical practice, received the same dose of tamoxifen tablet-in-capsule orally once daily for the remainder of 5-year period.

Outcome Measures

1. Primary Outcome
Title Disease-Free Survival (DFS) at Month 36 Post-Randomization: Main Study
Description 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.
Time Frame Baseline up to Month 36

Outcome Measure Data

Analysis Population Description
Intent-to-treat (ITT) population included all participants assigned to the treatment group to which they were randomized, irrespective of the treatment they actually received.
Arm/Group Title Exemestane Tamoxifen
Arm/Group Description Participants diagnosed with breast cancer who remained disease-free after previously receiving 2 to 3 years of tamoxifen 20 milligram (mg) or 30 mg tablet-in-capsule orally once daily as per standard medical practice, received exemestane (Aromasin) 25 mg tablet-in-capsule orally once daily for the remainder of 5-year period.

2. Secondary Outcome
Title Overall Survival (OS) at Month 36 Post-Randomization: Main Study
Description 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.
Time Frame Baseline up to Month 120

Title 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
Description 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.

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. '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. Results for 30, 36, 48, 60 months were not reported because data for these time points was only summarized as graphical presentation.

Description The FACT-ES assessed health-related QoL in participants with breast cancer. ES subscale comprised of 18 items (hot flushes,cold sweats,night sweats, vaginal discharge,vaginal irritation,vaginal bleeding,vaginal dryness,discomfort with intercourse,lost interest in sex,gained weight,light headed/dizzy,vomiting,had diarrhea,headaches,felt bloated,breast tenderness,mood swings, felt irritable).Participants indicated how true a statement was for them using a 5-point scale from 0 (not at all) to 4 (very much). For items that were negatively framed, the scores were reversed for the analysis so that higher scores equated to a good QoL. Total FACT-ES score was calculated as sum of all the 18 items and ranged from 0 to 72, where higher score indicated better QoL. '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.

Title Change From Baseline in Emotional Well-Being (EWB) Subscale Score at 3, 6, 9, 12, 18, 24, 30, 36, 48 and 60 Months: QoL Sub-study
Description The EWB subscale assessed emotional well-being related QoL in participants with breast cancer. EWB subscale comprised of 6 items (felt sad, proud of coping, lost hope, felt nervous, worried about dying, worried about condition worsening). Participants indicated how true a statement had been for them using a 5-point scale from 0 (not at all) to 4 (very much). For items that were negatively framed, the scores were reversed for the analysis so that higher scores equate to a good QoL. Total EWB score was calculated as the sum of the 6 items and ranged from 0 to 24, where higher score indicated better emotional well-being related QoL. '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.
