Antihypertensive Effect of Rostafuroxin Compared With Losartan in Hypertensive Patients Bearing Specified Gene Mutations
Recruitment status was Not yet recruiting
The principal aim of the study is to demonstrate that Rostafuroxin is able to induce a more pronounced reduction of arterial blood pressure respect to Losartan, in hypertensive patients carrying at least one of the pre-specified gene mutations. In previous studies has been demonstrated that these mutations are able to induce specific alterations inducing an increase of sodium (Na) reabsorption at renal tubular level and an increase of arterial blood pressure. Pilot studies have demonstrated that Rostafuroxin is able to reduce the impact of these alterations, and so directly reverse the increase in blood pressure.

- Systolic Blood Pressure [ Time Frame: Week 9 of treatment versus baseline ] [ Designated as safety issue: No ]
Automated sitting and standing SBP and DBP will be recorded by physician at baseline (two visits) and at week 2, 5 and 9 of treatement.
sitting: after the patient has rested for at least 10 minutes in a quiet room. There are five consecutive sitting BP readings with a 30 to 60 seconds interval between the readings; the mean of the last three sitting BP will be used.
The standing BP is measured twice immediately after the patient assumed the standing position.
- Diastolic blood pressure [ Time Frame: Baseline (two visits) and then at week 2, 5 and 9 of treatment ] [ Designated as safety issue: No ]Diastolic blood pressure measurements will be performed at the same times of the systolic blood pressure measurements, as described above.
- Trough-to-peak ratio on Systolic Blood Pressure [ Time Frame: Throughout 24 hours ABPM ] [ Designated as safety issue: No ]Ambulatory Blood Pressure Monitoring (ABPM)will be performed throuhgout 24 hours at baseline and at week 9 of treatement. Readings will be Centralized. The Core Laboratory will be in charge for data interpretation.
- Number of participants with adverse events [ Time Frame: throughout all the study period and follow-up (30 days) ] [ Designated as safety issue: No ]All the Adverse Events will be recorded and followed-up till their resolution. Number of Adverse Events in each group treatment will be computed, including single event frequencies and number of patients with adverse events. AEs will be collected on spontaneous reporting by patients and a number of standard safety procedure: i.e. recording of ECGs, standard blood chemistry and haematology, performed before, during and at the end of the treatment period.
