Primary Outcome Measures
NameTimeMethod
Progression-Free Survival (PFS), as Determined by the Investigator According to Response Evaluation Criteria in Solid Tumors, Version 1.1 (RECIST v1.1)From randomization to the first occurrence of disease progression or death from any cause, whichever occurs first (up to a clinical cutoff of 15 months)

PFS was defined as the time from randomization to the first occurrence of disease progression as determined by the investigator according to RECIST v1.1, or death from any cause (whichever occurs first). Disease progression was defined as ≥20% increase in the sum of diameters of target lesions, unequivocal progression in non-target lesions, and/or appearance of new lesions.

Secondary Outcome Measures
NameTimeMethod
Overall Survival (OS)From randomization to death from any cause (up to approximately 36 months)

OS is defined as the time from randomization to death from any cause.

Duration of Response (DOR), as Determined by the Investigator According to RECIST v1.1From first occurrence of documented objective response to disease progression or death from any cause, whichever occurs first (up to approximately 36 months)

DOR is defined as the time from the first occurrence of a documented objective response to disease progression as determined by the investigator according to RECIST v1.1 or death from any cause (whichever occurs first). Objective response rate is defined as the percentage of participants with a CR or PR on two consecutive occasions at least 4 weeks apart. Per RECIST v1.1, CR is defined as disappearance of all target and non-target lesions. Any pathological lymph nodes must have reduction in short axis to \<10 millimeters (mm). PR is defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR. Disease progression is defined as ≥20% increase in the sum of diameters of target lesions, unequivocal progression in non-target lesions, and/or appearance of new lesions.

Investigator-Assessed PFS, in Subgroups Categorized by Estrogen Receptor 1 (ESR1) Mutation StatusFrom randomization to the first occurrence of disease progression or death from any cause, whichever occurs first (up to a clinical cutoff of 15 months)

PFS was defined as the time from randomization to the first occurrence of disease progression determined by the investigator according to RECIST v1.1 or death from any cause (whichever occurs first). Disease progression was defined as ≥20% increase in in the sum of diameters of target lesions, unequivocal progression in non-target lesions, and/or appearance of new lesions. Investigator-assessed PFS was analyzed in subgroups categorized by baseline ESR1 mutation status (i.e., with or without ESR1 mutation at baseline) from plasma circulating tumor deoxyribonucleic acid (ctDNA).

Time to Deterioration (TTD) in Pain SeverityFrom Baseline until treatment discontinuation (up to approximately 36 months)

TTD in pain severity is defined as time to first documented ≥2-point increase from Baseline in the "Worst Pain" item from the Brief Pain Inventory-Short Form (BPI-SF) Questionnaire. The BPI-SF is a self administered questionnaire developed to assess the severity of pain (the sensory dimension) as well as the degree to which pain interferes with function (the reactive dimension). The BPI-SF uses 10-point numeric rating scale, with 0="No pain", "No interference" to 10="Pain as bad as you can imagine", "Highest imaginable interference". A lower score indicates improvement.

TTD in Physical Functioning (PF)From Baseline until treatment discontinuation (up to approximately 36 months)

TTD in PF is defined as the time to first documented ≥10-point decrease from baseline in the EORTC QLQ-C30 linearly transformed PF scale score. EORTC QLQ-C30 is a validated and reliable self-report measure that consists of 30 questions assessing five aspects of participant functioning (physical, emotional, role, cognitive, and social), three symptom scales (fatigue, nausea and vomiting, pain), global health and quality of life, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties) with a recall period of the previous week. The PF scale has 5 questions about participants' physical functioning and is scored on a 4-point scale (1=Not at All to 4=Very Much). The obtained scores are linearly transformed to a score range of 0-100, where higher scores indicate a higher response level (better physical function).

Objective Response Rate, as Determined by the Investigator According to RECIST v1.1From randomization until disease progression or death (up to approximately 36 months)

The objective response rate is defined as the percentage of participants with a complete response (CR) or partial response (PR) on two consecutive occasions at least 4 weeks apart. Per RECIST v1.1, CR is defined as disappearance of all target and non-target lesions. Any pathological lymph nodes must have reduction in short axis to \<10 millimeters (mm). PR is defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR.

Clinical Benefit Rate, as Determined by the Investigator According to RECIST v1.1From randomization until disease progression or death (up to approximately 36 months)

The clinical benefit rate is defined as the percentage of participants with stable disease for ≥24 weeks or a CR or PR. Per RECIST v1.1, CR is defined as disappearance of all target and non-target lesions. Any pathological lymph nodes must have reduction in short axis to \<10 millimeters (mm). PR is defined as at least a 30% decrease in the sum of diameters of all target lesions, taking as reference the baseline sum of diameters, in the absence of CR.

TTD in Pain Presence and Interference, Defined as Time to First Documented ≥10-Point Increase From Baseline in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)-C30 Linearly Transformed Pain Scale ScoreFrom Baseline until treatment discontinuation (up to approximately 36 months)

EORTC QLQ-C30 is a validated and reliable self-report measure that consists of 30 questions assessing five aspects of participant functioning (physical, emotional, role, cognitive, and social), three symptom scales (fatigue, nausea and vomiting, pain), global health and quality of life, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties) with a recall period of the previous week. The functioning and symptoms items are scored on a 4-point scale that ranges from 1=not at all to 4=very much. The Pain scale is scored on a 4-point scale (1=Not at All to 4=Very Much). The obtained scores are linearly transformed to a score range of 0-100, where higher scores indicate worse pain symptoms.

TTD in Role Functioning (RF)From Baseline until treatment discontinuation (up to approximately 36 months)

TTD in RF is defined as the time to first documented ≥10-point decrease from baseline in the EORTC QLQ-C30 linearly transformed RF scale score. EORTC QLQ-C30 is a validated and reliable self-report measure that consists of 30 questions that assessing five aspects of participant functioning (physical, emotional, role, cognitive, and social), three symptom scales (fatigue, nausea and vomiting, pain), global health and quality of life, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties) with a recall period of the previous week. The RF scale is scored on a 4-point scale (1=Not at All to 4=Very Much). The obtained scores are linearly transformed to a score range of 0-100, where higher scores indicate better functioning/support.

Number of Participants With Vital Sign Abnormalities Over the Course of the StudyAssessed at Baseline and predose on Day 1 of every cycle (1 cycle is 28 days) until 30 days after the final dose of study drug (up to approximately 36 months)

Vital signs include respiratory rate, pulse rate, systolic and diastolic blood pressure while the patient is in a seated position, and temperature.

TTD in Global Health Status and Quality of Life (GHS/QoL)From Baseline until treatment discontinuation (up to approximately 36 months)

TTD in GHS/QoL is defined as the time to first documented ≥10-point decrease from baseline in the EORTC QLQ-C30 linearly transformed GHS/QoL scale score. EORTC QLQ-C30 is a validated and reliable self-report measure that consists of 30 questions that assessing five aspects of participant functioning (physical, emotional, role, cognitive, and social), three symptom scales (fatigue, nausea and vomiting, pain), global health and quality of life, and six single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties) with a recall period of the previous week. The GHS/QoL scale has 7 possible scores of responses (1=very poor to 7=excellent). The obtained scores are linearly transformed to a score range of 0-100, where higher scores indicate a better QoL.

Plasma Concentration of Giredestrant at Specified TimepointsPredose and postdose on Day 1 of Cycles 1 and 2, predose on Day 1 of Cycles 3, 5, 7, 9, 11, 13, and 15 (1 cycle is 28 days), and 30 days after final dose of study drug (up to approximately 36 months)
