February 26, 2024 updated by: Hoffmann-La Roche

A Phase II, Randomized, Open-Label, Multicenter Study Evaluating the Efficacy and Safety of GDC-9545 Compared With Physician's Choice of Endocrine Monotherapy in Patients With Previously Treated Estrogen Receptor-Positive, HER2-Negative Locally Advanced or Metastatic Breast Cancer

This Phase II, randomized, open-label, multicenter study will evaluate the efficacy and safety of giredestrant compared with physician's choice of endocrine monotherapy in participants with estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer who have received one or two prior lines of systemic therapy in the locally advanced or metastatic setting.

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.

Time Frame: From 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.
From Baseline until treatment discontinuation (up to approximately 36 months)
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 Score
Time Frame: From 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.
From Baseline until treatment discontinuation (up to approximately 36 months)
TTD in Physical Functioning (PF)
Time Frame: 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).
From Baseline until treatment discontinuation (up to approximately 36 months)
TTD in Role Functioning (RF)
Time Frame: 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.

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