QOL-ACD-B is a part of QOL-ACD (using questionnaire items 1 to 18). QOL-ACD is a score used for cancer participants treated with anti-cancer drug and is a 22-item self-reported instrument assessing differences in symptom severity and health-related QOL. Participants answer each question on a 5-point scale (1: not at all [worst response] to 5: very much [best response]). Total score was calculated over score range 0-100 for item 1 to 18 as ((a sum of 18 items)/18-1)*25). Score for physical condition and pain was calculated over score range 0-100 for item 1 to 6 as ((a sum of 6 items)/6-1)*25)). Score for health-care and illness satisfaction was calculated over score range 0-100 for item 7 to 10 as ((a sum of 4 items)/4-1)*25)), where less scores reflect greater symptom severity and symptom impact on health-related quality of life. Means and standard deviations were calculated for the total score and score of each subscale from questionnaire items 1 to 18.

The question was with regard to the assessment of convenience associated with the changes in agents, "The change in agents reduced the frequency of injections by one third; for this reason, did you feel relief from physical and emotional burden?" and the answers were categorized as felt extreme relief, felt slight relief, no feeling either way, felt little relief, felt no relief.

The question was with regard to the assessment of convenience associated with the changes in agents, "Did you feel relief from financial burden (example, 3 months' drug costs and transportation fee) due to the change in agents?" and the answers were categorized as felt extreme relief, felt slight relief, no feeling either way, felt little relief, felt no relief. The sum of all the categories is not 100% because of rounding error.

The question was with regard to the assessment of convenience associated with the changes in agents, "The change in agents reduced the frequency of injections by one third; for this reason, did you worry about the effect?" and the options of the answers were not at all worried, not too worried, no thought either way, somewhat worried, and very worried.

The question was with regard to the assessment of convenience associated with the changes in agents, "Was there a change in adverse drug reactions (e.g., menopausal-like symptoms such as hot flushes, injection-site abnormalities) due to the change in agents?" and the options of the answers were events became much less severe, events became less severe, whether or not the events became severe cannot be determined, events became slightly more severe, and events became very severe.

The question was with regard to the assessment of convenience associated with the changes in agents, "Was there a change in pain at the time of injection due to the change in agents?" and the options of the answers were significantly relieved, slightly relieved, whether or not the pain worsened or was relieved cannot be determined, worsened slightly, and worsened significantly.

Adverse drug reactions are defined as adverse events (AE) which are in the investigator's opinion of causal relationship to the study treatment. AE are defined as any unfavorable and unintended signs, symptoms or diseases temporally associated with the use of a medicinal product reported from the first dose of study drug to the last dose of study drug.

Serious adverse drug reactions are defined as serious adverse events (SAE) which are in the investigator's opinion of causal relationship to the study treatment. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. The event was occurred in breast cancer female.

Following are Eastern Cooperative Oncology Group (ECOG) grades. 0: Fully active, perform all pre-disease activities without restriction. 1: Restricted in physically strenuous activity but ambulatory, carry out work of a light or sedentary nature. 2: Ambulatory, capable of self-care, unable to carry out any work activities, up and about greater than (>)50% of waking hours. 3: Capable of limited self-care, confined to bed or chair >50% of waking hours. 4: Completely disabled, not capable of any self-care, totally confined to bed or chair.

Participants were categorized as outpatient and inpatient.

Only 492 participants had data available for blood estradiol levels.

QOL-ACD score is a score used for cancer participants treated with anti-cancer drug and is a 22-item self-reported instrument assessing differences in symptom severity and health-related QOL. It includes 4 subscale domains: Daily Activities, Physical Condition, Social Activities, Mental and Psychological Status. Total and subscale scores are calculated as sum of items within each subscale: Daily Activity (items 1-6), Physical Condition (7-11), Psychological Condition (12-16), Social Attitude (17-21) and total (1-22). Face scale:5-point score for 1 item (22). Participants answer each question on a 5-point scale (1: not at all [worst response] to 5: very much [best response]). Score range for total score is 22 to 110 and subscale score range for daily activity is 6 to 30, and for physical condition, psychological condition, and social attitude is 5 to 25. Less total/subscale scores reflect greater symptom severity and symptom impact on health-related QOL.

Efficacy assessment population where Week 12 assessment for total and subscale scores were available. Efficacy assessment population included those participants who received at least one dose of study medication and had efficacy data available.
