Brief summary

The study is a prospective, multicenter, observational study to evaluate PRO and physical activity using smartphone-based application and wearable device in Japanese patients with HR+/HER2- advanced breast cancer (ABC). Patients will be enrolled into either palbociclib plus endocrine therapy group (Group 1) or endocrine monotherapy group (Group 2) based on the discretion of the treating physician under routine clinical practice. Total target number of patients is approximately one-hundred in this study (About 50 patients in each group). Enrolled patients will download a smartphone-based application for electronic PRO (ePRO), be provided access to and trained on the use of the application to complete baseline, weekly, and cycle-based assessments for 6 cycles (24 weeks). In addition, enrolled patients will be provided with wearable device and requested to wear the device at all-times, except of while bathing and sleeping, for 6 cycles (24 weeks).

Interventions

As a low-interventional procedure, enrolled patients will be provided with wearable device and requested to wear the device at all-times, except of while bathing and sleeping, for 6 cycles (24 weeks).

The EORTC-QLQ-C30 is a 30-item questionnaire to evaluate cancer participants' QOL, and it is composed of five multi-item functional subscales (physical, role, emotional, cognitive, and social functioning), three multi-item symptom scales (fatigue, nausea/vomiting, and pain), a GHS/QOL subscale, and six single item symptom scales assessing other cancer-related symptoms (dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, and the financial impact of cancer). The GHS/QOL was scored on a 7-point Likert scale where 1=very much to 7=not at all. Responses to GHS/QOL subscales were converted to a 0 to 100 scale. For GHS/QOL subscale, higher scores indicated a better QOL. Baseline values were those measured between enrollment and the day before treatment start.

Time frame: Baseline, Cycle 2 (1 cycle = 4 weeks)

Population: Evaluable population included all eligible participants who were enrolled in the study and who responded to at least 1 item or measured at least 1 metrics of study application or device. Participants were analyzed according to the enrolled group. Here, 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure.

Change From Baseline in Sedentary Time Wearing at Week 9

Sedentary time was used to assess physical activity metrics. Sedentary time was derived by Actigraph's algorithm based on raw data collected by Actigraph Insight Watch. Physical activity metrics were averaged at weekly basis which included 5 or more days of wearing the device for 10 hours or longer during a day except for bedtime.

Time frame: Baseline, Week 9

Population: Evaluable population included all eligible participants who were enrolled in the study and who responded to at least 1 item or measured at least 1 metrics of study application or device. Participants were analyzed according to the enrolled group. Here, 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure.

Change From Baseline in EORTC-QLQ-C30 Functional Sub-scale Scores at Cycle 1, Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6

The EORTC-QLQ-C30 is a 30-item questionnaire to evaluate cancer patients' QOL, and it's composed of five multi-item functional subscales (physical \[P\], role \[R\], emotional \[E\], cognitive \[C\], and social \[S\] functioning \[F\]). Response to functional scales is based on a 4-point Likert scale and ranges from 'not at all' to 'very much'. Responses to all functional sub-scales were converted to a 0 to 100 scale. For functional sub-scale, higher scores indicated a better level of functioning.

Time frame: Baseline, Cycle 1, Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6 (each cycle=4 weeks)

Population: Evaluable population included all eligible participants who were enrolled in the study and who responded to at least 1 item or measured at least 1 metrics of study application or device. Participants were analyzed according to the enrolled group. All participants reported under 'Overall Number of Participants Analyzed' contributed data to table but may not have evaluable data for every row. Here, 'Number Analyzed' signifies number of participants analyzed for the specific timepoints.

Change From Baseline in EORTC-QLQ-C30 Symptomatic Sub-scale Scores at Cycle 1, Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6

The EORTC-QLQ-C30 is a 30-item questionnaire to evaluate cancer patients' QOL, and it's composed of three multi-item symptom scales (fatigue, nausea/vomiting, and pain), a global QOL) subscale, and six single item symptom scales assessing other cancer-related symptoms (dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, and the financial impact of cancer). Response to symptom sub-scales is based on a 4-point Likert scale and a higher score indicated more severe symptoms. Responses to all symptom sub-scales were converted to a 0 to 100 scale. A higher score indicated more severe symptoms. A 10-point or higher change in scores from baseline was considered clinically significant.

Time frame: Baseline, Cycle 1, Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6 (each cycle=4 weeks)

Population: Evaluable population included all eligible participants who were enrolled in the study and who responded at least 1 item or measured at least 1 metrics of study application or device. Participants were analyzed according to the enrolled group. All participants reported under 'Overall Number of Participants Analyzed' contributed data to table but may not have evaluable data for every row. Here, 'Number Analyzed' signifies number of participants evaluable for the specific timepoints.

EORTC-QLQ-C30 GHS and Functional Sub-scale Score Before and After Disease Progression: Group 1 and 2 Pooled

The EORTC-QLQ-C30 is a 30-item questionnaire to evaluate cancer participants' QOL,it's composed of five multi-item functional subscales (physical \[P\],role \[R\],emotional \[E\],cognitive \[C\], and social \[S\] functioning \[F\], three multi-item symptom scales (fatigue,nausea/vomiting,pain) a GHS/QOL subscale,and six single item symptom scales assessing other cancer-related symptoms (dyspnea, sleep disturbance, appetite loss, constipation,diarrhea,and the financial impact of cancer). The GHS/QOL was scored on a 7-point Likert scale where 1=very much to 7=not at all. Response to functional scales is based on a 4-point Likert scale and ranges from 'not at all' to 'very much'. Responses to GHS/QOL and all functional sub-scales were converted to a 0 to 100 scale. For GHS/QOL and functional subscale, higher scores indicated a better QOL and better level of functioning, respectively. Disease progression was defined as \>25% increase in sum of longest diameter of target lesions compared to baseline.

Time frame: Before and after disease progression during the observation period (maximum up to 24 weeks)

Population: Safety Analysis set included all participants who received at least 1 dose of palbociclib or endocrine therapy. As per statistical analysis plan, when associations for group 1 and 2 were similar, the data for group 1 and 2 were pooled. Here, 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure. Here, 'Number Analyzed' signifies number of participants evaluable for the specific rows.

Number of Participants According to Fatigue Interference Based on PRO-CTCAE

The PRO-CTCAE is a PRO measurement system that includes a library of questions that measures symptomatic adverse events from the participant perspective. Participants were required to provide their responses to the questions on fatigue interference on a five-point Likert scale. For Fatigue Interference (FI) scoring was as follows: 0= Not at all/None/Never, 1= A Little bit, 2: Somewhat, 3= Quite a bit, 4= Very much.

Time frame: Baseline, Cycle 1, Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6 (each cycle=4 weeks)

Population: Evaluable population included all eligible participants who were enrolled in the study and who responded to at least 1 item or measured at least 1 metrics of study application or device. Participants were analyzed according to the enrolled group. Here, 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure.

Number of Participants According to Fatigue Severity Based on Patient Reported Outcome - Common Terminology Criteria for Adverse Events (PRO-CTCAE)

The PRO-CTCAE is a PRO measurement system that includes a library of questions that measures symptomatic adverse events from the participant perspective. Participants were required to provide their responses to the questions on fatigue severity on a five-point Likert scale. For Fatigue Severity (FS) scoring was as follows: 0= None, 10= Mild, 20= Moderate, 30= Severe, 40= Very Severe.

Time frame: Baseline, Cycle 1, Cycle 2, Cycle 3, Cycle 4, Cycle 5, Cycle 6 (each cycle=4 weeks)

Population: Evaluable population included all eligible participants who were enrolled in the study and who responded to at least 1 item or measured at least 1 metrics of study application or device. Participants were analyzed according to the enrolled group. Here, 'Overall Number of Participants Analyzed' signifies participants evaluable for this outcome measure. Here, 'Number Analyzed' signifies number of participants evaluable for the specific rows.

AE= any untoward medical occurrence,could therefore be any unfavorable,unintended sign (including an abnormal laboratory finding),symptom,or disease,whether or not related to the participant's participation in the study. An SAE was any untoward medical occurrence at any dose that:resulted in death;was life-threatening(LT);required inpatient hospitalization or prolongation of existing hospitalization;resulted in persistent or significant disability/incapacity(substantial disruption of the ability to conduct normal life functions);resulted in congenital anomaly/birth defect;or an important medical event. AEs were graded(G) according to Common Terminology Criteria for AE(CTCAE) version 4.03. G3 (Severe AE),G4 (LT consequences;urgent intervention indicated),G5 (Death related to AE). TEAEs were those events with onset dates occurring during the on-treatment period (the time from start of study treatment up to 28 days after last dose). Relatedness was based on the investigator's judgement.
