Clinical Trial Summary
The Cardio-Oncology program at Northwestern offers care to cancer patients who develop
cardiac toxicities from chemotherapy. Breast cancer patients with the tumor marker for HER2
necessitate treatment with anthracycline and/or trastuzumab and pertuzumab-based
chemotherapies, which are known to cause cardiac toxicities. Breast cancer patients will
undergo a "cardio-oncology echocardiogram" which incorporates advanced left ventricular
assessment by utilizing deformation or strain imaging during chemotherapy treatment for
surveillance of cardiac toxicities. The aims of this project are:
1. To create a registry of both clinical, and echocardiographic variables, biomarkers, and
genetic analysis that will be used to develop a risk model to predict LV dysfunction in
early stage breast cancer patients undergoing chemotherapy with anthracycline and/or
trastuzumab and pertuzumab-based chemotherapy regimens.
2. To propose a new management algorithm for initiation of prophylactic beta-blocker
therapy for early stage breast cancer patients with preclinical cardiac toxicities
demonstrated by strain parameters.
3. To determine if initiation of prophylactic beta-blocker therapy in patients with early
cardiac toxicity can delay or prevent a drop in LV EF and the development of clinical
heart failure.
4. To explore serial measurements of a suite of novel biomarkers during ongoing anticancer
treatment that are presumed but not yet proven to be predictive of cardiac dysfunction
in women with breast cancer.
5. To identify DNA biomarkers of predilection to cardiotoxicity.
6. To generate hiPSC to validate markers predictive of cardiotoxicity.
Description:
150 patients will be prospectively consented/screened. Over the course of the study, 30
patients are expected to develop abnormal strain with a normal EF > 53%. They will be
randomized in 1:1 fashion to open label carvedilol vs. no treatment.
All consenting patients will receive a baseline echocardiogram and blood draw for biomarkers
and genetic testing. Patients will be followed with echocardiograms at 3 month intervals for
12 months, until completion of trastuzumab/pertuzumab therapy.
Based on echocardiogram findings, patient will fall into four study arms (A, B, C, D).
Patients in Arm A (normal EF and normal strain) and Arm D (decrease in EF > 10%, to a value
<53%) will receive current standard of care treatment and will be followed in a registry arm.
Arms B and C will comprise of 30 patients with normal EF who develop preclinical cardiac
dysfunction, as defined as a change in global longitudinal strain of > 15% from baseline
strain) or < -15% absolute longitudinal strain will be prospectively assigned 1:1 to receive
prophylactic carvedilol (Arm B) vs. no treatment (Arm C). Prophylactic carvedilol will be
initiated at the starting dose of 3.125 mg PO BID and titrated based on blood pressure and
heart rate.
Patients will be seen every 3 weeks during the titration phase at their chemotherapy
appointments. At each visit, vitals and symptoms will be assessed for dizziness and
side-effects from carvedilol. If patient complains of dizziness or HR < 50 bpm, or SBP < 100
mmHg, then the dose titration should stop and the dose should be reduced to the dose at the
last increased increment. If there is a > 10% decrease in EF to a value < 53% on the next
echocardiogram, then standard heart failure therapy will be initiated (beta-blocker and/or
ace-inhibitors) and chemotherapy will be held as per standard of care. If patients require
other standard of care treatments for heart failure, such as diuretic therapy or aldosterone
antagonists, then this will also be initiated. At this point, these patients will be
considered to have met the study endpoint. However, if there is an improvement or no change
in strain and EF, then patients will continue with cardiac surveillance with an echo at 3
month intervals. Patients who have been assigned to receive prophylactic carvedilol will
continue treatment for duration of chemotherapy up to 1 year. Prophylactic carvedilol will be
stopped at the completion of study.
A biomarker substudy will be conducted on 100 patients. These patients will have labs drawn
every at ten time points, baseline and every 6 weeks for 12 months, and 1 year
post-chemotherapy. A separate blood draw for generation of hiPSC and DNA testing would be
done for 100 patients. The blood collection will coincide with the patient's chemotherapy
infusions with trastuzumab. These biomarkers will allow for further characterization of
patients at risk for developing CTRCD.
A "cardio-oncology" echocardiogram will include standard 2D M-mode and Doppler
echocardiography, 2D strain imaging, and 3D LV volume. This data will be processed on-line or
off-line within 24 hours of completion of the echocardiogram to determine randomization.
