Sanctura Muscarinic Receptor Antagonist Resists Transport (SMART) Trial - Full Text View

Purpose

This study evaluates the penetration through the blood-brain-barrier of trospium chloride at plasma steady state (Day 10) in elderly subjects with overactive bladder symptoms. Trospium levels in cerebrospinal fluid (CSF) and peak and trough plasma levels will be measured. Baseline and day 10 post-dose neurocognitive testing will be compared using a reliable change index to assess if any study subject shows evidence of a clinically and statistically significant change in memory.

Primary Outcome Measures:

Cerebral Spinal Fluid Levels of Trospium at Day 10, Hour 5 [ Time Frame: Day 10, Hour 5 ] [ Designated as safety issue: No ]
Cerebral spinal fluid levels of Trospium at day 10, hour 5. Cerebral spinal fluid was collected from each patient.

Secondary Outcome Measures:

Percentage of Study Subjects With No Clinically Significant Effect on Neurocognitive Function Total Recall Score as Measured by the Hopkins Verbal Learning Test-Revised (HVLT-R) at Day 10 Post-Dose [ Time Frame: Day 10 ] [ Designated as safety issue: No ]
The HVLT-R is an instrument used to measure verbal learning and memory (recognition and recall). It consists of 3 learning trials: free recall, delayed recall, and yes/no delayed recognition. The total recall score was the sum of 3 'free recall' learning trials, and reflects the patient's ability to learn. The total score ranges from 0 (no memory) to 36 (best memory).
Percentage of Study Subjects With No Clinically Significant Effect on Neurocognitive Function Delayed Recall Score as Measured by the Hopkins Verbal Learning Test-Revised (HVLT-R) at Day 10 Post-Dose [ Time Frame: Day 10 ] [ Designated as safety issue: No ]
The HVLT-R is an instrument used to measure verbal learning and memory (recognition and recall). It consists of 3 learning trials: free recall, delayed recall, and yes/no delayed recognition trial. The delayed recall score provides a measure of the patient's recent memory. The total score ranges from 0 (no memory) to 12 (best memory).
Percentage of Study Subjects With No Clinically Significant Effect on Neurocognitive Function as Measured by the Brief Visuospatial Memory Test-Revised (BVMT-R) Total Score at Day 10 Post-Dose [ Time Frame: Day 10 ] [ Designated as safety issue: No ]
The BVMT-R is an instrument used to measure visual learning and memory (recognition and recall). It consists of 3 learning trials: free recall, delayed recall, and yes/no delayed recognition trial. The total recall score is the sum of 3 free recall learning trials, and reflects the patient's ability to learn. The total score ranges from 0 (no memory) to 12 (best memory). Due to technical problems associated with the administration of the test, the results were invalid.
Percentage of Study Subjects With No Clinically Significant Effect on Neurocognitive Function as Measured by the Brief Visuospatial Memory Test-Revised (BVMT-R) Delayed Recall Score at Day 10 Post-Dose [ Time Frame: Day 10 ] [ Designated as safety issue: No ]
The BVMT-R is an instrument used to measure visual learning and memory (recognition and recall). It consists of 3 learning trials: free recall, delayed recall, and a yes/no delayed recognition trial. The delayed recall score, derived from the delayed recall trial, provides a measure of the patient's recent memory. The total score ranges from 0 (no memory) to 12 (best memory). Due to technical problems associated with the administration of the test, the results were invalid.
