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 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.

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
Left Ventricular Ejection Fraction (LVEF) by Cardiac MRI
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LVEF is a measure of contractility of the heart (strength of contraction). Normal values are between 55-65%. It is the most widely used parameter by physicians worldwide to measure cardiac contractility.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.

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
Longitudinal Strain of Left Ventricle (LV)
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
Longitudinal strain is the deformation of a material per unit length, defined as the ratio of change in length to the original length in the direction of an applied load. It measures how much an object stretches (tensile) or compresses (compressive) along its axis Longitudinal strain is an echocardiographic technique that quantifies the percentage of systolic shortening of the heart muscle from base to apex. It is a highly sensitive indicator of left ventricular function, detecting subclinical, early myocardial dysfunction (e.g., in cardio-oncology) often before the ejection fraction (LVEF) drops. Normal GLS values are typically >18%.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LVEF by 3D-Echocardiography
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LVEF is a measure of contractility of the heart (strength of contraction). Normal values are between 55-65%. It is the most widely used parameter by physicians worldwide to measure cardiac contractility.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LV Volumes by MRI
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LV volumes measure how enlarged the heart is. Chemotherapy destroys cardiac muscle and enlarges the heart (ie. increases LV volumes). The higher the LV volumes, the more damage by chemotherapy.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LV Mass by MRI
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LV mass measures the amount of cardiac muscle. Chemotherapy destroys cardiac muscle. The lower the LV mass, the more damage by chemotherapy.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
LV Longitudinal Strains by MRI
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
Longitudinal strain is the deformation of a material per unit length, defined as the ratio of change in length to the original length in the direction of an applied load. It measures how much an object stretches (tensile) or compresses (compressive) along its axis Longitudinal strain is an echocardiographic technique that quantifies the percentage of systolic shortening of the heart muscle from base to apex. It is a highly sensitive indicator of left ventricular function, detecting subclinical, early myocardial dysfunction (e.g., in cardio-oncology) often before the ejection fraction (LVEF) drops. Normal GLS values are typically >18%.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
6-Minute Walk Test (6MWT)
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
The 6MWT assesses endurance and ability to walk over longer distances. The 6MWT was first described as a field test for physical fitness in 1963 and then as a 12-minute walk test in people with chronic bronchitis. The 6MWT was found to perform as well as the 12-minute walk, and is now used to assess the submaximal level of functional performance at a similar level required for daily physical activities.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
NT-ProBNP
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
NT-ProBNP is a plasma biomarker of cardiac stress, cardiac tension and severity of heart failure. The higher the NT-ProBNP level, the more severe the heart failure induced by chemotherapy.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
Troponin I
Time Frame: Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
Troponin I is a plasma biomarker of cardiac injury and cardiac damage. The higher the troponin levels, the more cardiac damage induced by chemotherapy.
Baseline and end of study, one month after completion of anthracycline treatment, up to 9-10 months.
