NCT06023576

Brief Summary

The purpose of this study to find out whether an intensive approach to treating high blood pressure during breast cancer treatment is safe and more effective than standard blood pressure treatment at lowering blood pressure levels and the risk of cardiotoxicity in patients with cancer. Other studies have shown lowering blood pressure improves the health of patients. However, these studies have not included people with cancer. The PROTECT trial is testing a treatment strategy regarding intensive versus standard SBP goals, and is not testing specific medications.

Outcome Measures

Primary Outcomes (1)

  • mean change in systolic blood pressure (SBP) from baseline to 12 months

    based upon in-office measurement

    12 months

Study Arms (2)

standard-of-care antihypertensive medications

EXPERIMENTAL

SBP control will consist of treatment with antihypertensive medications titrated every 4 weeks for the first 3 months, and then every 3 months in months 4-12. SBP control will be achieved by titration of antihypertensive medications based upon a standardized algorithm and will be implemented during a 12-month study period. At the time of randomization, no antihypertensive treatments may be initiated or modified if SBP is ≥160 mm Hg. The clinical context may be considered at each visit to inform decision-making regarding treatment initiation or modification, at the discretion of the treating provider.

higher dose antihypertensive medications

EXPERIMENTAL

Patients randomized to intensive SBP control will be treated to achieve an SBP goal \<120 mm Hg, and patients randomized to standard SBP control will be treated to achieve an SBP goal \<140 mm Hg. Antihypertensive medications will be titrated on the basis of seated blood pressure measurements obtained after a 5-min rest period. All participants will be provided with dietary (e.g., 1500mg/d sodium restriction) and lifestyle recommendations as background therapy for optimizing HTN control.The clinical context may be considered at each visit to inform decision-making regarding treatment initiation or modification, at the discretion of the treating provider.

Interventions

One or more of the following medications may be used in both randomization groups to achieve SBP goals: * Angiotensin converting enzyme inhibitors (ACEI) * Angiotensin receptor blockers (ARBs) * Beta-blockers (BB) * Thiazide-type diuretics * Calcium channel blockers * Aldosterone antagonists * Alpha1-receptor blockers. * Direct vasodilators * Loop diuretics

Home BP Monitoring (HBPM)-Throughout the study period, patients will perform HBPM at baseline, month 6, and month 12 (end of treatment). At each of these timepoints, HBPM will be performed for 7 days with 2 morning and 2 evening readings for each day (measured 1-min part).

Consecutive patients in each treatment group who meet the eligibility criteria for exercise testing will be offered to participate in CPET at the time of consent. Patients who agree will undergo CPET (baseline, 6 months, and 12 months) until the target accrual of 33 patients per group is met.
