Device Study for Intranasal Delivery of Insulin
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The SNIFF Device study will involve using a device to administer insulin through each participant's nose or intra-nasally. Insulin is a hormone that is produced in the body. It works by lowering levels of glucose (sugar) in the blood. This study is measuring how much insulin the device delivers. In addition, this study will look at the effects of insulin or placebo administered intra-nasally using a nebulizer-like device on memory, blood, and cerebral spinal fluid.
