Trial Outcomes & Findings for ALiskiren or Losartan Effects on bioMARKers of Myocardial Remodeling (NCT NCT01176032)

NCT ID: NCT01176032

Last Updated: 2014-07-24

Results Overview

PICP is a measure of blood concentration of procollagen I carboxy-terminal propeptide (PICP), a peptide released from the myocardium when procollagen is converted to type I collagen. This biomarker exhibits good specificity and sensitivity for identifying myocardial fibrosis in hypertension.

Population: Intention-to-treat (ITT) population included all patients included in the safety population who had a baseline assessment of the primary variable and at least one post-baseline assessment

Response rate was defined as the proportion of patients with a satisfactory systolic BP response (SBP \< 140 mmHg or reduction of ≥ 10 mmHg compared to baseline) and a satisfactory diastolic BP response (DBP \< 90 mmHg or reduction of ≥ 5 mmHg compared to baseline)

Population: Intention-to-treat (ITT) population included all patients included in the safety population who had a baseline assessment of the primary variable and at least one post-baseline assessment

The rate of use of first and second antihypertensive rescue drugs added was also assessed at all visits after week 2. The rescue drug at week 10 and 18 for those patients not achieving the required BP was amlodipine, Patients who did not achieve the required BP at week 26 were treated with hydrochlorothiazide
