Brief Summary:

The overarching goal of this study is to determine the role of chronic kidney disease and the activation of the kallikrein-kinin system during hemodialysis on the development of mitochondrial dysfunction; the investigators will measure mitochondrial function using the gold standard method, 31-phosphorus magnetic resonance spectroscopy.

The investigators will test the hypothesis that endogenous bradykinin promotes mitochondrial dysfunction in patients undergoing hemodialysis. The investigators will first perform a randomized, placebo-controlled, double-blind, cross-over study measuring the effect of Icatibant (HOE-140), a bradykinin B2 receptor blocker, on mitochondrial function.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 11 participants
Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Mitochondrial Dysfunction in Chronic Kidney Disease
Actual Study Start Date : August 1, 2017
Actual Primary Completion Date : June 30, 2018
Actual Study Completion Date : December 31, 2018


Arm Intervention/treatment
Experimental: Icatibant
Icatibant will be intravenously infused at a rate of 50 ug/kg/h for 1 hour prior to the initiation of dialysis and continue through hemodialysis (4 hours)
Drug: Icatibant
Subjects will receive either Icatibant or placebo in the first study day. After a washout period of 3 weeks, participant will receive the other treatment. Icatibant (50µg/kg/h) or placebo will be infused for 1 hour prior to the initiation of dialysis and continue through hemodialysis. Hemodialysis session will last approximately 4 hours. Two hours after the end of hemodialysis, The investigators will evaluate mitochondrial function by 31 phosphorus magnetic resonance spectroscopy.
Other Name: HOE-140

Placebo Comparator: Placebo
Placebo will be intravenously infused at the same rate of Icatibant (50 ug/kg/h) for 1 hour prior to the initiation of dialysis and continue through hemodialysis (4 hours)
Drug: Placebo
Subjects will receive either Icatibant or placebo in the first study day. After a washout period of 3 weeks, participant will receive the other treatment. Icatibant (50µg/kg/h) or placebo will be infused for 1 hour prior to the initiation of dialysis and continue through hemodialysis. Hemodialysis session will last approximately 4 hours. Two hours after the end of hemodialysis, the investigators will evaluate mitochondrial function by 31 phosphorus magnetic resonance spectroscopy.




Primary Outcome Measures :
  1. 31 Phosphorus Magnetic Resonance Spectroscopy (31P-MRS) [ Time Frame: Up to 2 hours after completion of drug infusion ]
    Mitochondria function will be evaluated using 31P-MRS, which evaluates the concentration of phospho-creatine (PCr) and other phosphate-energy carrier molecules. After basal measurements, subjects will be asked to perform 90 seconds of knee extension followed by 4 minutes of rest. The exercise/rest cycle will be repeated 3 times. Magnetic resonance spectra will be used to calculate concentrations of inorganic phosphate (Pi), PCr, and adenosine triphosphate (ATP). The half-time of PCr recovery (time to achieve half of maximal concentration during recovery) will be used to determine mitochondrial function.


Secondary Outcome Measures :
  1. Blood Pressure [ Time Frame: 30 minutes before hemodialysis, during dialysis, and up to 1 hour after hemodialysis ]
    Blood pressure will be monitored every 15 minutes, before, during, and after hemodialysis.
