Study population

Community sample of PAD-ESKD subjects

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • ≥55 years of age or ≥45 years of age with diabetes
  • Receiving maintenance HD in a clinical setting for at least 2 weeks prior to screening
  • Resting ABI \<0.90 in either leg OR Resting TBI \<0.70 in either leg

Exclusion criteria

Exclusion Criteria:

  • Above-ankle amputation
  • Chronic limb-threatening ischemia (Rutherford 4-6)
  • Non-ambulatory status
  • A condition other than PAD that limits ability to walk
  • Open or endovascular revascularization within 3 months prior to baseline.
  • Illnesses, conditions, or planned surgeries within the study period that will interfere with the interpretation of the study results

What researchers measure

Primary outcomes

  1. Six Minute Walk Test

    Walking distance in meters completed over a duration of 6 minutes

    Time frame: Two six minute walk tests will be conducted separated by 5-7 days during Week 1 during the subject's participation of up to 4 weeks.

  2. Activity Patterns

    Actigraphy measurements as 24 hour intervals of motion using an accelerometer device

    Time frame: Functional activity measurements will be collected daily beginning at the completion of screening and daily for the duration of the subject's participation of up to 4 weeks.

  3. Ankle Brachial Index

    Compares blood pressure in upper extremities and lower extremities

    Time frame: Will be conducted once in a vascular laboratory during the screening visit or visits during the subject's participation of up to 4 weeks

  4. Toe Brachial Index

    Compares blood pressure in upper extremities and lower extremities

    Time frame: Will be conducted once in a vascular laboratory during the screening visit or visits during the subject's participation of up to 4 weeks

  5. San Diego Claudication Questionnaire

    Will categorize the subject's perception of the leg symptoms associated with PAD

    Time frame: Administered once during Day 1 of the screening visit during subject's participation of up to 4 weeks.

  6. Walking Impairment Questionnaire

    Will evaluate the subjects personal perception of walking ability.

    Time frame: Administered once during Week 1 during subject's participation of up to 4 weeks.

  7. PAD Quality of Life

    Will evaluate information about the subject's perception of social relationships, self-concepts and feelings, symptoms and limitations in physical functioning, fear and uncertainly, and positive adaptation.

    Time frame: Administered once during Week 1 during subject's participation of up to 4 weeks.

  8. EQ-SD-SL Health Questionnaire

    Will evaluate the subject's perception of overall health status, mobility, self-care, usual activities, pain or discomfort, and anxiety or depression.

    Time frame: Administered once during Week 1 during subject's participation of up to 4 weeks

  9. Pulse Wave Velocity - Sub-Study

    Measures arterial stiffness

    Time frame: Will be conducted once in a vascular lab for subjects participating the in the sub-study during Week 3 of the subjects participation of 4 weeks.

  10. Flow-Mediated Dilation - Sub-Study

    Measures the ability of blood vessels to dilate

    Time frame: Will be conducted once in a vascular lab for subjects participating the in sub-study during Week 3 of the subjects participation of 4 weeks.

  11. Nitroglycerin-Medicated Dilation - Sub-Study

    Measures the ability of blood vessels to dilate after administration of nitroglycerin

    Time frame: Will be conducted once in a vascular lab for subjects participating the in sub-study during Week 3 of the subjects participation of 4 weeks.

  12. Lower limb calcification measurements

    A non-contrast computed tomography scan of the lower extremities will be evaluated for arterial calcification.

    Time frame: Will be conducted once in subjects participating the in sub-study during Week 3 of the subjects participation of up to 4 weeks.
