Study of Predictors of Clinical Outcomes in Patients With HR+ and HER2-low/Negative Breast Cancer

February 23, 2024 updated by: Daiichi Sankyo

Identify Predictors of Clinical Outcomes in Real-world Patients With HR+ and HER2-low/Negative Breast Cancer Treated With Neoadjuvant Chemotherapy or Endocrine Therapy

There is a lack of data on clinical and patient factors that are associated with poor survival in patients with HR+ and HER2-low/negative breast cancer treated with neoadjuvant chemotherapy or endocrine therapy. This retrospective, non-interventional study is designed to assess the predictors of clinical outcomes in this patient population. No study drug will be provided as part of this study protocol.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This retrospective, non-interventional study is designed to assess the following primary objectives:

  1. To identify predictors of event-free survival (EFS) in patients with HR+ and HER2-low/negative breast cancer treated with neoadjuvant chemotherapy or endocrine therapy, and
  2. To stratify patients according to event-free survival using different combinations of significant predictors and evaluate the patient characteristics and clinical outcomes such as EFS, overall survival and pathological complete response across patient groups of different risk level.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Sampling Method

Non-Probability Sample

Study Population

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
Event-free survival (EFS) in Participants With HR+ and HER2-Low/Negative Breast Cancer
Time Frame: Index date to the end of the study period (approximately December 31, 2022)
Events of interest include any other primary cancer, metastases, higher stage, tumor progression, and death due to any cause.
Index date to the end of the study period (approximately December 31, 2022)
Overall Survival of Participants With HR+ and HER2-Low/Negative Breast Cancer
Time Frame: Index date to the end of the study period (approximately December 31, 2022)
Index date to the end of the study period (approximately December 31, 2022)
Pathological Complete Response (pCR) in Participants With HR+ and HER2-Low/Negative Breast Cancer
Time Frame: Index date to the end of the study period (approximately December 31, 2022)
Pathological complete response (pCR) was defined as ypT0/Tis ypN0 and is the absence of any invasive component in the resected breast specimen and all resected lymph nodes following completion of neoadjuvant therapy.
Index date to the end of the study period (approximately December 31, 2022)

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
