Cardiotoxicity of Targeted Therapy for HER-2 Positive Breast Cancer Patients at High Altitude

September 30, 2021 updated by: Jiuda Zhao, Affiliated Hospital of Qinghai University

Cardiotoxicity of Targeted Therapy for HER-2 Positive Breast Cancer Patients at High altitude-a Multicenter, Prospective Cohort Study

This is a prospective, multicenter, cohort study aiming to explore the cardiotoxicity of targeted therapy for HER-2 positive breast cancer patients who lives in high altitude area. One hundred and thirty two HER-2 positive breast cancer patients who will receive neoadjuvant, adjuvant, or palliative targeted therapy will be enrolled. The cardiotoxicity of targeted therapy will be observed and recorded during the treatment and one year after the end of treatment. The subjects will be stratified by age, baseline cardiac risk factors, and anthracyclines.

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

HER-2 positive breast cancer patients who live at high altitudes greater than 2000 meters for long periods of time and will receive trastuzumab-based targeted therapy will be enrolled. The subjects included early and advanced patients. Treatment regimens includes chemotherapy combined with trastuzumab, chemotherapy combined with trastuzumab and pertuzumab, trastuzumab alone, and trastuzumab plus pertuzumab. Electrocardiogram, cardiac ultrasound, NT-proBNP, and TNI will be tested every 3 months when the treatment begins. The primary endpoint is cardiotoxity. The second endpoints is pathologic complete response (pCR) rate in neoadjuvant therapy, objective remission rate (ORR) and disease control rate (DCR) in neoadjuvant and palliative therapy.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

All enrolled patients are from four centers of Qinghai province.

Description

Inclusion Criteria:

  1. Histologically confirmed invasive HER2-positive breast cancer.
  2. The baseline left ventricular ejection fraction >55%.
  3. Living at high altitude area （>2000 meters）for at least 10 years.
  4. ECOG score 0-2.
  5. Expected survival time ≥ 12 months.

Exclusion Criteria:

  1. Patients with previous breast cancer or other malignant tumor within 5 years.
  2. Patients who had accepted previous anti-HER2 or anthracyclines-based therapy.
  3. Patients with severe heart disease or discomfort.
  4. Patients who are pregnant.
  5. Patients with other conditions considered not suitable to be enrolled by the investigator.

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
Incidence rate of cardiotoxicity
Time Frame: 5 years
Cardiotoxicity includes death from cardiac cause, severe congestive heart failure (New York Heart Association Class III or IV), more than 10% decrease of left ventricular ejection fraction (LVEF) and to below 50%, and an asymptomatic or mildly symptomatic (NYHA class II) substantial decrease in LVEF.
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.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Anticipated)

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.
October 1, 2021

Primary Completion (Anticipated)

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.
