Primary Outcome Measures

Change From Baseline in Tumor Cell Proliferation, as Measured by the Proportion of Nuclei Staining Ki67-Positive at Surgery Relative to Baseline in Pre- and Post-Treatment Tumor Biopsy Samples
The biological response to the study treatment was assessed by measuring changes in cell proliferation (Ki67 expression) using formalin-fixed paraffin-embedded histopathology sections of the tumor biopsy specimens taken at baseline and at day of surgery. Baseline was defined as a sample taken prior to initiation of study drug. The results show the proportion of nuclei staining Ki67-positive (Ki67+) in the tumor biopsy sample taken post-treatment (at surgery) relative to that in the pre-treatment sample (at baseline).
Change From Baseline in Tumor Cell Proliferation, as Measured by the Difference in the Percentage of Nuclei Staining Ki67-Positive at Surgery Compared With Baseline in Pre- and Post-Treatment Tumor Biopsy Samples
The biological response to the study treatment was assessed by measuring changes in cell proliferation (Ki67 expression) using formalin-fixed paraffin-embedded histopathology sections of the tumor biopsy specimens taken at baseline and at day of surgery. Baseline was defined as a sample taken prior to initiation of study drug. The results show the percentage of nuclei staining Ki67-positive (Ki67+) in the pre- and post-treatment tumor biopsy samples (taken at baseline and surgery, respectively) and the absolute difference in the percentage of Ki67+ nuclei between the two samples (calculated as surgery minus baseline).

Secondary Outcome Measures

Number of Participants With at Least One Adverse Event and by Severity, Determined According to National Cancer Institute Common Terminology Criteria for Adverse Events, Version 5.0 (NCI-CTCAE v5.0)
All adverse events (AEs) were recorded and the investigator independently assessed the seriousness and severity of each AE. AE severity was graded on a scale from 1 to 5 using the NCI-CTCAE v5.0; any events not specifically listed in the scale were defined as: Grade 1 is mild; Grade 2 is moderate; Grade 3 is severe or medically significant; Grade 4 is life-threatening; and Grade 5 is death related to an AE. Investigators used their knowledge of the patient, the circumstances surrounding the event, and an evaluation of any potential alternative causes to determine whether an AE was considered to be related to the study drug.
Percentage of Participants With Abnormal Vital Signs During Treatment
Vital signs, which included diastolic and systolic blood pressure, pulse rate, and body temperature, were measured while the participant was sitting and according to institutional practices. Any of the vital signs that were outside of the normal reference range (in the specified direction - low or high) were considered abnormalities. Not every abnormality qualified as an adverse event (AE). A vital sign result had to be reported as an AE if it met any of the following criteria: was accompanied by clinical symptoms; resulted in a change in study treatment; resulted in a medical intervention or a change in concomitant therapy; or was clinically significant in the investigator's judgment.
Change From Baseline in Pulse Rate
Pulse rate was measured while the participant was in a seated position. The baseline value at visit and the change from baseline value at each timepoint are reported. The change from baseline value was calculated by subtracting the post-baseline value from the baseline value. The post-baseline minimum and maximum change from baseline values are, respectively, the smallest and largest value changes obtained after baseline through the last study visit. Baseline was defined as the participant's last value prior to initiation of study drug.
Change From Baseline in Systolic Blood Pressure
Systolic blood pressure was measured while the participant was in a seated position. The baseline value at visit and the change from baseline value at each timepoint are reported. The change from baseline value was calculated by subtracting the post-baseline value from the baseline value. The post-baseline minimum and maximum change from baseline values are, respectively, the smallest and largest value changes obtained after baseline through the last study visit. Baseline was defined as the participant's last value prior to initiation of study drug.
Change From Baseline in Diastolic Blood Pressure
Diastolic blood pressure was measured while the participant was in a seated position. The baseline value at visit and the change from baseline value at each timepoint are reported. The change from baseline value was calculated by subtracting the post-baseline value from the baseline value. The post-baseline minimum and maximum change from baseline values are, respectively, the smallest and largest value changes obtained after baseline through the last study visit. Baseline was defined as the participant's last value prior to initiation of study drug.
Change From Baseline in Body Temperature
Body temperature was measured according to institutional practice. The baseline value at visit and the change from baseline value at each timepoint are reported. The change from baseline value was calculated by subtracting the post-baseline value from the baseline value. The post-baseline minimum and maximum change from baseline values are, respectively, the smallest and largest value changes obtained after baseline through the last study visit. Baseline was defined as the participant's last value prior to initiation of study drug.
Percentage of Participants With Laboratory Abnormalities in Hematology Tests During Treatment, Among Participants Without the Abnormality at Baseline
Laboratory parameters for hematology will be measured and compared with a standard reference range. Any of the laboratory test results that were outside of a parameter's normal reference range (in the specified direction - low or high) were considered abnormalities. Not every laboratory abnormality qualified as an adverse event (AE). A laboratory test result was reported as an AE if it met any of the following criteria: was accompanied by clinical symptoms; resulted in a change in study treatment; resulted in a medical intervention or a change in concomitant therapy; or was clinically significant in the investigator's judgment.
Percentage of Participants With Laboratory Abnormalities in Blood Chemistry and Coagulation Tests During Treatment, Among Participants Without the Abnormality at Baseline
Laboratory parameters for blood chemistry and coagulation were measured and compared with a standard reference range. Any of the laboratory test results that were outside of a parameter's normal reference range (in the specified direction - low or high) were considered abnormalities. Not every laboratory abnormality qualified as an adverse event (AE). A laboratory test result was reported as an AE if it met any of the following criteria: was accompanied by clinical symptoms; resulted in a change in study treatment; resulted in a medical intervention or a change in concomitant therapy; or was clinically significant in the investigator's judgment. SGPT/ALT = alanine aminotransferase; SGOT/AST = aspartate aminotransferase
Percentage of Participants With Abnormal Electrocardiogram Parameters During Treatment
Electrocardiogram (ECG) recordings were performed after the participant had been resting in a supine position for at least 10 minutes. ECG parameters included heart rate, PR and QRS durations, and QT and QTcF intervals. Per the protocol, ECG readings post-treatment were limited to those for whom it was clinically indicated. Any of the ECG parameters that were outside of the normal reference range (in the specified direction - low or high) were considered abnormalities. Not every abnormality qualified as an adverse event (AE). An ECG test result was reported as an AE if it met any of the following criteria: was accompanied by clinical symptoms; resulted in a change in study treatment; resulted in a medical intervention or a change in concomitant therapy; or was clinically significant in the investigator's judgment.
Plasma Concentration of Giredestrant at Steady State by Dose Level
Plasma samples were obtained on the day of surgery (Day 15), or prior to biopsy on Day 14.
