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 study is a multi-center, prospective. Because of the non-interventional nature of this study, the choice of H can be trastuzumab, biosimilar drugs Hantriyou, enituzumab, etc. The CDK4/6 inhibitor can be piperazil, abecilil and the like. AI can be letrozole, anastrozole, exemestane. This study does not change or interfere with clinicians' diagnosis and treatment decisions, as well as patients' actual medical practices.This real-world study will not do formal inference statistical analysis. All hypothesis testing is exploratory. A comprehensive statistical analysis plan (SAP) will be prepared and finalized before the data is locked and analyzed. Descriptive statistics will be performed, including the number and percentage of categorical variables, as well as the number, average, standard deviation, median, maximum, and minimum of continuous variables. Kaplan-Meier survival analysis was used to calculate the median PFS and OS and their 95% confidence intervals. The median time to disease progression and median survival time will also be calculated, as well as its 95% confidence interval. ORR and CBR will be analyzed and expressed by the ratio and the corresponding 95% confidence interval (CI). The multivariate logistic regression model was used to calculate the odds ratio (OR) and its 95% confidence interval and p-value. The subgroup analysis of PFS and OS was analyzed by Log-rank test. The COX proportional hazard regression model is used to calculate the hazard ratio and its 95% confidence interval.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
