What is the purpose of this trial?

This phase III trial studies how well carvedilol works in preventing cardiac toxicity in patients with human epidermal growth factor receptor (HER)-2-positive breast cancer that has spread to other places in the body. A beta-blocker, such as carvedilol, is used to treat heart failure and high blood pressure, and it may prevent the heart from side effects of chemotherapy.

Will I have to stop taking my current medications?

If you are currently taking a beta blocker, ARB, or ACE inhibitor, you cannot participate in the randomized part of the trial but may join the non-randomized observational group. Additionally, you must not take certain medications like B2 agonists, bosutinib, and others during the study.

Is carvedilol safe for humans?

Carvedilol, also known as Coreg, has been used safely in humans for conditions like heart failure and high blood pressure. It is generally well tolerated, though some people may experience side effects related to its heart and blood pressure effects. ^{1 2 3 4 5}

How does the drug carvedilol differ from other treatments for preventing heart problems in HER2 positive breast cancer?

Carvedilol is unique because it not only blocks certain receptors in the heart to improve heart function but also has antioxidant properties that may protect against heart damage caused by cancer treatments like anthracyclines. This makes it potentially effective in preventing heart problems in breast cancer patients, which is not a standard use for other heart medications. ^{1 2 4 5 6}

What data supports the effectiveness of the drug Carvedilol in preventing heart problems in HER2 positive breast cancer patients?

Carvedilol has been shown to lower the risk of heart damage caused by chemotherapy in cancer patients, as it reduces the incidence of noticeable heart problems and prevents changes in heart size after treatment. ^{1 2 4 7 8}

Are You a Good Fit for This Trial?

This trial is for adults with HER-2-positive metastatic breast cancer who are starting or continuing trastuzumab-based therapy. They must have normal heart function, blood pressure, and not be on certain heart medications. Pregnant or nursing individuals can't join, nor those with other recent cancers except some specific cases.

Inclusion Criteria

Your heart's pumping ability must be at least 50% as measured by a special heart ultrasound within 28 days before joining the study.

Your liver enzyme levels are within five times the normal range.

Patients must not co-enroll on other treatment trials

What Are the Treatments Tested in This Trial?

Interventions

• Carvedilol

Trial Overview The study tests if carvedilol can prevent heart damage in patients receiving cancer treatment for HER-2-positive metastatic breast cancer. It involves taking the beta-blocker carvedilol alongside standard chemotherapy to see if it reduces cardiac toxicity.

How Is the Trial Designed?

Group I: Arm I (carvedilol) Experimental Treatment 2 Interventions

Patients not taking beta blocker, ARB, or ACE inhibitor at registration receive carvedilol PO BID. Courses repeat every 12 weeks for 108 weeks in the absence of disease progression or unacceptable toxicity.

Group II: Arm II (no intervention) Active Control 1 Intervention

Patients not taking beta blocker, ARB, or ACE inhibitor at registration receive no study intervention for up to 108 weeks.

Group III: Arm III (observation) Active Control 2 Interventions

Patients undergo observation for up to 108 weeks.

Published Research Related to This Trial

Carvedilol significantly improves left ventricular ejection fraction (LVEF) and reduces mortality in patients with chronic heart failure (CHF), as shown in multiple studies including the US Carvedilol Heart Failure Trials Program with 1094 participants.

Compared to metoprolol, carvedilol demonstrated lower mortality rates in patients with CHF, indicating it may be the preferred beta-blocker for treatment, while also being well tolerated with fewer adverse events compared to placebo.

Carvedilol (CAR) significantly reduces the migration and invasion of breast cancer cells, indicating its potential as an anti-metastatic agent.

The mechanism of action involves the inhibition of Src activation through different signaling pathways: the cAMP/PKA-Src pathway in MDA-MB-231 cells and the PKCδ-Src pathway in MCF-7 cells.

A study assessed the pharmaceutical quality of Dilatrend (carvedilol) and 35 generic products, revealing that while all Dilatrend strengths met specifications, nearly 49% of the generics failed to meet key quality standards.

The failure of many generic products in tests for carvedilol content, tablet hardness, dissolution, and purity raises concerns about their efficacy and safety, suggesting that substituting Dilatrend with these generics could lead to unpredictable treatment outcomes.

In a study of 40 breast cancer patients undergoing chemotherapy, the combination of low-dose carvedilol and candesartan significantly reduced the acute and chronic cardiotoxic effects of anthracycline drugs compared to chemotherapy alone.

Patients receiving the combination treatment maintained better left ventricular ejection fraction (LVEF) and had lower rates of cardiac abnormalities, indicating that this approach may effectively protect heart health during cancer treatment.

In a systematic review of six randomized controlled trials involving beta-blocker carvedilol, there was no significant difference in left ventricular ejection fraction (LVEF) after chemotherapy compared to placebo, indicating it may not prevent early asymptomatic heart function decline.

However, carvedilol was associated with a lower incidence of clinically overt cardiotoxicity and prevented increases in left ventricular end-diastolic diameter, suggesting it may help protect against more severe heart damage during cancer treatment.

Carvedilol significantly reduces cardiac damage caused by severe hypertension in stroke-prone spontaneously hypertensive rats, with reductions in various histopathologic indices such as coronary artery hypertrophy and myocardial inflammation by up to 100%.

Despite not affecting systolic blood pressure, carvedilol effectively prevents cardiac remodeling and myopathies associated with a high-salt, high-fat diet, demonstrating its potential for cardioprotection without lowering systemic blood pressure.

In a review of nine randomized controlled trials involving 717 patients, carvedilol showed potential benefits in preventing anthracycline-induced cardiotoxicity, particularly by improving left ventricular ejection fraction (LVEF) and possibly reducing the incidence of left ventricular systolic dysfunction (LVSD).

Despite these positive findings, the studies had significant variability in their definitions and reporting of LVSD, and there was no evidence of decreased mortality associated with carvedilol use, indicating the need for further research with larger sample sizes and longer follow-up periods.

In a study of 23 breast cancer patients undergoing anthracycline treatment, carvedilol showed a trend towards better right ventricular (RV) function compared to those receiving only chemotherapy, although the differences were not statistically significant.

The use of carvedilol was associated with a significantly higher RV S wave tissue Doppler imaging (S-TDI) measurement, suggesting a potential protective effect on RV function during cancer treatment.
