Trial Outcomes & Findings for Safety and Effectiveness Study of Intranasal Insulin Glulisine on Cognitive and Memory in Mild-Mod AD Patients. (NCT NCT01436045)

NCT ID: NCT01436045

Last Updated: 2015-10-19

Results Overview

The results are presented as a mean number of correct responses for each cognitive assessment. For each of these, a lower number correct is indicative of a higher cognitive deficit. Ranges are as follows: RBANS List Learning (0-40), RBANS Story Memory (0-24), RBANS Figure Copy (0-20), RBANSLine Orientation (0-20), RBANS Semantic Fluency (0-unlimited), RBANS List Recall (0-10), RBANS List Recognition (0-20), RBANS Story Recall (0-12), RBANS Figure Recall (0-20), Digit Span Forward (0-16), Digit Span Backward (0-16), Boston Naming (0-15).

PRIMARY outcome

Timeframe: 20 minutes post-intranasal administration

The results are presented as the number of seconds to complete Trails B. For each of these, a higher number of seconds is indicative of a higher cognitive deficit.

SECONDARY outcome

Timeframe: 60 minute post intranasal administration

The Sniff Magnitude Test (SMT) measures olfactory function not influenced by cognitive problems (minimal dependence on language, cognitive ability, memory, and odor naming ability). Sniff magnitude ratios are calculated as a ratio of sniff magnitudes (area under the sniff curve). Lower sniff magnitude ratios indicate more impairment. \[average sniff magnitude of malodor/average sniff magnitude to a null odor\]
