Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Progression-free survival (PFS)
Time Frame: Baseline up to 3.5 years
The time from the date of randomization to the date of the first documentation of objective progression of disease (PD), clinically diagnosed symptomatic deterioration, or death due to any cause in the absence of documented PD, whichever occurs first.
Baseline up to 3.5 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Overall Survival (OS)
Time Frame: From the randomization of the last patient up to 3 years
The time from date of randomization to date of death due to any cause.
From the randomization of the last patient up to 3 years
Survival Probabilities at 1 year, 2 year, and 3 year
Time Frame: From the randomization of the last patient up to 3 years
The probability of survival 1 year, 2 or 3 years after the date of randomization based on the Kaplan-Meier estimate.
From the randomization of the last patient up to 3 years
Objective Response (OR)
Time Frame: Baseline up to 3.5 years
Complete response (CR) or partial response (PR) according to Response Evaluation Criteria In Solid Tumors (RECIST) ver.1.1 recorded from randomization until disease progression or death due to any cause.
Baseline up to 3.5 years
Duration of Response (DR)
Time Frame: Baseline up to 3.5 years
The time from the first documentation of objective tumor response (CR or PR) to the first documentation of objective tumor progression or to death due to any cause, whichever occurs first.
Baseline up to 3.5 years
Clinical Benefit Response (CBR)
Time Frame: Baseline up to 3.5 years
CR or PR or SD >=24 weeks according to the RECIST version 1.1 recorded in the time period between randomization and disease progression or death of any cause.
Baseline up to 3.5 years
Change From Baseline Between Treatment Comparison in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) Functional Scale Scores
Time Frame: Baseline up to 3.5 years
The EORTC-QLQ-C30 is a 30-item questionnaire 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 global quality of life (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 questionnaire employs 28 4-point Likert scales with responses from "not at all" to "very much" and two 7-point Likert scales for global health and overall QOL. Responses to all items are then converted to a 0 to 100 scale. For functional and global QOL scales, higher scores represent a better level of functioning/QOL. For symptom-oriented scales, a higher score represents more severe symptoms. A 10-point or higher change in scores from baseline is considered clinically significant.
Baseline up to 3.5 years
Change From Baseline Between Treatment Comparison in European Organization for Research and Treatment of Cancer Breast Cancer Module (EORTC QLQ BR23) Functional Scale Scores
Time Frame: Baseline up to 3.5 years
The EORTC-QLQ-BR23 is a 23-item breast cancer-specific companion module to the EORTC-QLQ-C30 and consists of four functional scales (body image, sexual functioning, sexual enjoyment, future perspective) and four symptom scales (systemic side effects, breast symptoms, arm symptoms, upset by hair loss). QLQ-BR23 questionnaire employs 4-point scales with responses from 'not at all' to 'very much'. All scores are converted to a 0 to 100 scale. For functional scales, higher scores represent a better level of functioning.
Baseline up to 3.5 years
Trough plasma concentrations of palbociclib
Time Frame: Cycle 1/Day 15 and Cycle 2/Day 15
Ctrough for palbociclib
Cycle 1/Day 15 and Cycle 2/Day 15
Trough plasma concentrations of tamoxifen, 4-hydroxytamoxifen, N-desmethyltamoxifen and endoxifen
Time Frame: Cycle 2/Day 15 and Cycle 3/Day 15
Ctrough for tamoxifen, 4-hydroxytamoxifen, N-desmethyltamoxifen and endoxifen
