NCT04745104
A randomized, double-blind, placebo-controlled, single dose escalation phase 1 study to access the Pharmacokinetics and Pharmacodynamics of Single Intravenous Administration of SHR-1707
NCT05443308
Alzheimers disease and cerebral small vessel disease have a considerably overlap in patients and have common risk factors. The diseases are difficult to separate in individual patients and we hypothesize that a reduced cerebral vascular reserve may be a measurement of small vessel disease independent of Alzheimers disease. Patients with presumed Alzheimers disease (n=20), cerebral small vessel disease (n=20) and healthy age-matched subjects (n=15) are examined with quantitative \[15O\]H2O positron emission tomography (PET) for measurements of brain perfusion before and after diamox infusion that dilates cerebral vessels. Additional \[15O\]H2O PET scans of the heart allows for a non-invasive input function so the cerebral vascular reserve can be measured quantitatively.
NCT03405662
Photobiomodulation (PBM) describes the use of near-infrared light (which is not visible to the eye) to heal and protect tissue that has either been injured, is degenerating, or else is at risk of dying. Research suggests that the light delivered during PBM enhances the body's biochemical ability to store and use energy and increase blood flow, which triggers the body's natural healing processes. The primary goal of this study is to determine if PBM administered transcranially (through the scalp and skull) and intranasally (inside the nose) with a commercially available device is safe and tolerable for patients with mild-to-moderate Alzheimer's disease (AD). Secondary goals are to examine whether tPBM has an effect on cognitive function and behavioral symptoms in patients with AD and whether tPBM has an effect on fluid biomarkers of AD. A biomarker is a specific physical trait used to measure the progress of a disease or condition.
