A Study of Blood Pressure Control During Cancer Treatment

Официальное название

Intensive Blood Pressure Control During Cardiotoxic Breast Cancer Treatment (PROTECT), A Randomized Controlled Trial

Обзор

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.

Вмешательства

• Другое antihypertensive medications
  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
• Диагностический тест Blood pressure measurement
  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).
• Диагностический тест Echocardiogram
  At baseline, month 6, and month 12
• Другое Symptom-limited cardiopulmonary exercise test
  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.
• Другое Quality of Life Measures
  FACT-B, Fatigue Symptom Inventory (FSI), Patient Reported Outcomes Measurement Information System (PROMIS) Global Health Scale, Godin Leisure Time Exercise Questionnaire (GLTEQ),PROMIS Medication Adherence Scale. Given baseline, 3 months and 12 months.
• Диагностический тест Biomarkers
  Research blood samples will be collected at baseline, 3 months, and 6 months

Первичные конечные точки

• mean change in systolic blood pressure (SBP) from baseline to 12 months [Срок оценки: 12 months]
