Effect of Extended-release Oxymorphone Taken With or Without Food on Cognitive Functioning
May 8, 2023 updated by: MedVadis Research Corporation
Effect of Extended-release Oxymorphone Hydrochloride (Opana® ER), Taken Fasting Versus With Food, on Cognitive Functioning in Opioid-tolerant Subjects: a Randomized, Single-blinded, Cross-over Study
The purpose of the study is to determine whether extended-release oxymorphone hydrochloride taken orally with a high-fat meal, generating an approximately 50% higher Cmax, impacts cognitive functioning, using Cambridge Neuropsychological Test Automated Battery (CANTAB) tests, to a greater extent than when taking under conditions of fasting.
Study Overview
Detailed Description
Oxymorphone 40 mg ER affects cognitive performance similarly within 3 hours post dose, whether given on an empty stomach or after a high-fat meal, suggesting that the altered pharmacokinetics, fed versus fasting and as described above, is not relevant for the medication's impact on cognition.
Hence, the direction for oxymorphone ER to be dosed at least 1 hour before or 2 hours after eating, at least from a cognitive perspective, may be without merit.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Rapid Visual Information Processing (RVP) Sensitivity [A']
Time Frame: 1 and 3 hours postdose
|
RVP is a test of sustained attention.
It is a sensitive measure of general cognitive performance.
A white box appears in the center of the computer screen, inside which digits, from 2 to 9, appear in a pseudorandom order, at the rate of 100 digits per minute.
The subject is requested to detect target sequences of three digits (for example, 2-4-6, 3-5-7, 4-6-8) and to register responses using the response box.
The two main outcome measures are the probability to detect the predefined sequence (sensitivity [A']) and the speed at which the sequence is registered (response latency [ms]).

Spatial Recognition Memory (SRM) Test Percentage of Correct Hits
Time Frame: 1 and 3 hours postdose
|
SRM tests visual spatial recognition memory in a two-choice forced discrimination paradigm.
The subject is presented with a white square, which appears in sequence at five different locations on the screen.
In the recognition phase, the subject sees a series of five pairs of squares, one of which is in a place previously seen in the presentation phase.
The other square is in a location not seen in the presentation phase.
Locations are tested in the reverse of the presentation order.
The two main outcome measures are the percentage of correct trials (correct hits [%]) and the speed of the subject's response (response latency [ms]).

Spatial Working Memory (SWM) Test Total Errors
Time Frame: 1 and 3 hours postdose
|
SWM is a test of the subject's ability to retain spatial information and to manipulate remembered items in working memory.
It is a self-ordered task, which also assesses heuristic strategy.
The test is a sensitive measure of executive function.
It begins with a number of colored squares (boxes) being shown on the screen.
By touching the boxes and using a process of elimination, the subject finds blue tokens in a number of boxes and uses them to fill up an empty column on the screen.
The number of boxes is gradually increased, until it is necessary to search a total of eight boxes.
The color and position of the boxes are changed from trial to trial to discourage the use of stereotyped search strategies.
The two main outcome measures are errors (touching boxes that have been found to be empty and revisiting boxes that have already been found to contain a token - total errors) and a measure of strategy (strategy score).
