Brief Summary
Breast cancer patients undergoing trastuzumab-based HER2-directed therapy are at risk of heart function decline or heart failure symptoms, but it is unknown if, when, and for how long cardiovascular protective strategies, e.g. with a beta-blocker, could help. This study randomly assigns those taking curative-intent trastuzumab-based HER2-directed therapy to the beta-blocker carvedilol-either when significant heart function decline or subtle early signs of heart injury (either by elevation of a cardiac blood biomarker, i.e. cardiac troponin, or by an abnormal heart ultrasound marker, i.e. global longitudinal strain) are noted, or preventatively before beginning trastuzumab-based HER2-directed therapy. This study will further randomly assign those patients on carvedilol to either discontinuation at the end of trastuzumab-based HER2-directed therapy or continuation for another year, providing much needed clinical trial data on what the best strategy ("tactic") for those at risk of cardiotoxicity with trastuzumab-based HER2-directed therapy is.

Outcome Measures
Primary Outcomes (2)
Rate of asymptomatic and symptomatic cardiac dysfunction
Incidence of heart failure or asymptomatic decline in left-ventricular ejection fraction (LVEF) by \>10% in patients whose LVEF is ≥50% or LVEF drop ≥5% in those with a decrease to \<50% (primary outcome measure)
1 year
Rate of reversible cardiac function decline
Reversible LVEF decline to within 5% of baseline (secondary primary outcome measure)
1 year
Secondary Outcomes (2)
Cardiac function changes after completion of HER2-directed therapy
1 year
Gene variants and risk of cardiotoxicity and response to therapy
2 years
Study Arms (3)
Pre-Emptive Strategy
EXPERIMENTALCarvedilol titrated to maximally tolerated doses (3.125 mg to 25 mg twice a day) initiated one week before start of therapy and continued until end of therapy
Reactive Strategy
EXPERIMENTALCarvedilol titrated to maximally tolerated doses (3.125 mg to 25 mg twice a day) initiated after documentation of subclinical cardiotoxicity, defined by an abnormal global longitudinal strain (GLS) or high-sensitive cardiac troponin (hsTnI) elevation and continued until end of therapy
Standard of Care
ACTIVE COMPARATORCarvedilol titrated to maximally tolerated doses (3.125 mg to 25 mg twice a day) initiated after documentation of a drop in LVEF by \>10% to a value less than 53% and continued until end of therapy
Interventions
oral Carvedilol maximally tolerated doses 3.125 mg to 25 mg twice a day

- pregnancy
- Metastatic breast cancer (distant metastases)
- Active systemic treatment for non-breast cancer
