Trial Outcomes & Findings for Effect of Chronic ACE and DPP4 Inhibition on Blood Pressure (NCT NCT02130687)

NCT ID: NCT02130687

Last Updated: 2022-03-02

Results Overview

The primary analyses will focus on mean arterial blood pressure, heart rate, and norepinephrine (NE) concentrations during ramipril versus ramipril+sitagliptin, and during ramipril+sitagliptin versus ramipril+sitagliptin+aprepitant. We will make similar comparisons within the valsartan- and placebo-treated groups. In addition, we will compare blood pressure and heart rate parameters among the ramipril-treated, valsartan-treated, and placebo-treated groups during comparable concurrent treatment.

Measure
Amlodipine
Subjects in this arm will receive calcium channel blocker therapy with amlodipine 5mg daily for 3 days then 10mg daily for 15 weeks. After 4 weeks of treatment, subjects will receive three different 1 week concurrent interventions, in a cross-over fashion, separated by a 4 week washout. The interventions will be: placebo + placebo, sitagliptin + placebo, sitagliptin + aprepitant. Placebo: Subjects will receive two capsules of placebo to preserve the blinding of the study. In a separate period, subjects will receive one capsule of placebo and one capsule of sitagliptin. Sitagliptin: Subjects will receive sitagliptin 100mg daily for 7 days. In addition, subjects will receive either aprepitant or a capsule of placebo to preserve the blinding of the study. Aprepitant: Subjects will receive aprepitant (125 mg on the first day followed by 80mg/d) for 7 days along with sitagliptin. Mixed Meal Test (MMT): The first 18 subjects per arm/ group will undergo a mixed meal test on the 7th day of each medication intervention. This will take place after the first half of the study day at the clinical research center, following a 30 minute rest. Subjects will ingest a shake (combination of fixed carbohydrates/ fat/ protein) and have blood pressure, heart rate, and venous blood sample measurements collected for 4 hours after the meal.
Ramipril
Subjects will receive ACE-inhibitor therapy with ramipril 5mg daily for 3 days, followed by 10mg daily for the remaining 15 weeks. After 4 weeks of treatment, subjects will receive three different 1 week concurrent interventions, in a cross-over fashion, separated by a 4 week washout. The interventions will be: placebo + placebo, sitagliptin + placebo, sitagliptin + aprepitant. Placebo: Subjects will receive two capsules of placebo to preserve the blinding of the study. In a separate period, subjects will receive one capsule of placebo and one capsule of sitagliptin. Sitagliptin: Subjects will receive sitagliptin 100mg daily for 7 days. In addition, subjects will receive either aprepitant or a capsule of placebo to preserve the blinding of the study. Aprepitant: Subjects will receive aprepitant (125 mg on the first day followed by 80mg/d) for 7 days along with sitagliptin. Mixed Meal Test (MMT): The first 18 subjects per arm/ group will undergo a mixed meal test on the 7th day of each medication intervention. This will take place after the first half of the study day at the clinical research center, following a 30 minute rest. Subjects will ingest a shake (combination of fixed carbohydrates/ fat/ protein) and have blood pressure, heart rate, and venous blood sample measurements collected for 4 hours after the meal.
Valsartan
Subjects will receive ARB therapy with valsartan 160mg daily for 3 days, followed by 320mg daily for the remaining 15 weeks. After 4 weeks of treatment, subjects will receive three different 1 week concurrent interventions, in a cross-over fashion, separated by a 4 week washout. The interventions will be: placebo + placebo, sitagliptin + placebo, sitagliptin + aprepitant. Placebo: Subjects will receive two capsules of placebo to preserve the blinding of the study. In a separate period, subjects will receive one capsule of placebo and one capsule of sitagliptin. Sitagliptin: Subjects will receive sitagliptin 100mg daily for 7 days. In addition, subjects will receive either aprepitant or a capsule of placebo to preserve the blinding of the study. Aprepitant: Subjects will receive aprepitant (125 mg on the first day followed by 80mg/d) for 7 days along with sitagliptin.

This is a measure of activity of the angiotensin-converting enzyme (ACE). The assay is a kinetic assay (Labcore) that measures the rate of cleavage of an added ACE substrate over time and the results are reported in Units, which represent the rate of increase in fluorescent metabolite over 30 minutes under standard conditions at 37C.
