Hemodialysis.-Induced Hypotension Therapy for End Stage Kidney Disease

Description

Bradykinin is a potent vasodilator that is formed by the activation of the kallikrein-kinin system. We and others have shown that bradykinin increased during hemodialysis; however, the role of bradykinin in dialysis-induced hypotension (DIH) has not been evaluated. Preliminary results from a pilot clinical trial showed that bradykinin B2 receptor blockade with icatibant prevents excessive blood pressure during hemodialysis. Thus, in this study, we will test the overarching hypothesis that blockade plasma kallikrein with lanadelumab would ameliorate the reduction of blood pressure during hemodialysis in patients who are prone to DIH. For this purpose, we will conduct a parallel arm, double-blind placebo-controlled trial, using lanadelumab to evaluate the occurrence of

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Subjects age 18 to 85 years

  • * Hypotensive episodes should occur four times or more in four weeks (12 hemodialysis sessions).
  • * Subjects with intradialytic hypotension that require the use of pharmacological intervention such as midodrine or vasopressin
  • * Subjects with pre-dialytic systolic blood pressure greater than 170 mmHg or diastolic blood pressure greater than 110 mmHg
  • * History of myocardial infarction or cerebrovascular event within 3 months
  • * History of serious hemorrhage (including cerebral hemorrhage) in the past 6 months
