Study to Evaluate Patient Reported Outcome (PRO) and Physical Activity in Japanese Patients With HR+/HER2- Advanced Breast Cancer Treated With Palbociclib Plus Endocrine Therapy or Endocrine Monotherapy

NCT04736576

CompletedNA

Sponsor: Pfizer

Conditions: Breast Cancer

Interventions: Wearable device

Countries: Japan

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).

Eligibility criteria

Inclusion Criteria:

1. Adult women (≥ 20 years of age)
2. Diagnosis of adenocarcinoma of the breast with evidence of metastatic disease or advanced disease not amenable to resection or radiation therapy with curative intent.
3. Documented evidence of HR+/HER2- tumor based on the patient's surgical specimen or most recent tumor biopsy.
4. Initiating first or second line treatment at study entry with one of the following therapies:

palbociclib plus endocrine therapy or endocrine monotherapy
5. Eastern Cooperative Oncology Group (ECOG) performance status = 0\~1.
6. Owns or has regular access to an Apple iPhone or Android phone.
7. Willing and able to complete collection of data via smartphone-based application.
8. Willing and able to wear the wearable device for approximately 6 months.
9. Evidence of a personally signed and dated informed consent document indicating that the patient has been informed of all pertinent aspects of the study.
10. Able to read and understand Japanese

Exclusion Criteria:

1. The patient is participating in any interventional clinical trial that includes investigational or marketed products. Patients participating in other investigator-initiated research or non-interventional studies can be included as long as their standard of care is not altered by the study.
2. The patient is on active treatment for other malignancies other than ABC.
3. The patient's life style is fluctuating in weekly-basis (eg, shift-time worker), which may have high impact on physical activity assessment based to investigator's discretion
