Brief Summary:
The aim of this study is to assess the superiority of the new low sodium peritoneal dialysis (PD) solution PDsol 12 in comparison with a conventional, already marketed solution, Gambrosol trio 40, in the treatment of the hypertensive peritoneal dialysis patients with aim to decrease hypertension and to improve the sodium/water balance.

Condition or disease Intervention/treatment Phase
Chronic Kidney Failure Drug: Solution for Peritoneal Dialysis Phase 3

Detailed Description:

Hypertension as well as sodium and water retention are common in end-stage renal disease patients on peritoneal dialysis and expose patients to left ventricular hypertrophy and increase cardiovascular mortality.

Moreover the poor control of dry weight and sodium/water balance results in increased morbidity. A previous low sodium study and computer simulations show that sodium removal can be improved with a low sodium fluid, which allows achieving a negative sodium balance without altering water balance.

The aim of this study is to assess whether treatment with one low sodium bag can substitute for one isotonic glucose bag every day in order to reduce the blood pressure and/or medication for hypertension, defined as the primary endpoint.

In order to evaluate the main criteria, blood pressure, a 24hours Ambulatory Blood Pressure Monitoring (ABPM) will be performed twice during the study, at Baseline and at 8 weeks of treatment, according to the EMEA guidance recommendations for anti-hypertensive treatments. In addition, the self measurement of blood pressure will be performed by patients at home during three consecutive days before each visit as well as in case of symptoms of hypotension.

The study is designed in three periods:

  • Run-in period during 1 month: a reference product Gambrosol Trio 40, one bag/ day will be used by all patients. This period is dedicated to train the patient in using of study product, to stabilize the patient in the PD treatment and to randomize the patient, by performing the 24h ABPM.
  • Efficacy & Safety period during 6 months: each patient will be treated with one of two product : PDsol 12 (studied product) or Gambrosol Trio 40 (reference product) during 6 months. The aim of this period is to evaluate the efficacy and long-term tolerance of new PD fluid.
  • Follow-up period during 2 months: without treatment. This period is dedicated to ensure the safety of the patients after the study product treatment was stopped and to obtain the information about the reversibility of product effect.
