Overview
To evaluate the dose-response of relevant blood biomarkers to remote ischemic conditioning in patients with age-related cerebral white matter hyperintensities on MRI, in preparation for a subsequent larger efficacy trial.
Description
Objective: The objective of this early phase study is to evaluate the dose-response of relevant blood biomarkers to remote ischemic conditioning in preparation for a subsequent larger efficacy trial. In addition, we will evaluate the tolerability and adherence to the treatment protocol.
Aim: We aim to measure blood biomarkers in response to daily remote ischemic conditioning (RIC) using a dose escalation study design in 40 patients with age-related cerebral white matter hyperintensities on MRI.
Hypothesis: We hypothesize that there will be a significant change in the biomarker levels in a dose dependent fashion.
Eligibility
Inclusion Criteria:
- Age ≥55 years
- Head MRI in the past 6 months showing no more than moderate age related cerebral white matter changes (Fazekas score 0-2).
- Able to walk without assistance & independently perform basic activities of daily living.
- Able to understand this study and agree for a valid consent.
Exclusion Criteria:
Prior non-lacunar (cortical) stroke. 2. Unable to cooperate with the use of the
conditioning device. 3. Confounding illness that might interfere with the interpretation of
results (such as active malignancy or multiple sclerosis).
4. Contraindication to transient arm ischemia in either arm (such as symptomatic peripheral
artery disease).
