What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Number of Accurate Responses to Rapid Visual Information Processing (RVIP) Cognitive Test

    The RVIP assessed the performance of visual attention mechanisms in remaining vigilant to periodically occurring events. The number of accurate responses to RVIP task was determined from the cognitive function computerised output. Participants monitored a series of single numbers (0-9) appearing in the centre of the screen. During the RVIP task, participants responded to consecutive sequences of three odd or three even numbers by pressing the corresponding response button as quickly and accurately as possible. This was identified in the output file by a value of '1' in 'TARGET=1' column. Also, the response time (in seconds) was recorded in the 'RT' column. If the subject correctly responded to the target, this was identified by a value of '1' in the 'CORRECT=1' column. The number of accurate responses was calculated as the total number of records where 'CORRECT=1' had a value of '1'. The test lasted approximately 9 minutes and number of accurate responses to stimulus was calculated.

    Measured: Baseline to 60 minutes post treatment administration

Secondary outcomes (9)
  1. Change From Baseline in Number of Accurate Responses to RVIP Cognitive Test

    The RVIP assessed the performance of visual attention mechanisms in remaining vigilant to periodically occurring events. The number of accurate responses to RVIP task was determined from the cognitive function computerised output. Participants monitored a series of single numbers (0-9) appearing in the centre of the screen. During the RVIP task, participants responded to consecutive sequences of three odd or three even numbers by pressing the corresponding response button as quickly and accurately as possible. This was identified in the output file by a value of '1' in 'TARGET=1' column. Also, the response time (in seconds) was recorded in the 'RT' column. If the subject correctly responded to the target, this was identified by a value of '1' in the 'CORRECT=1' column. The number of accurate responses was calculated as the total number of records where 'CORRECT=1' had a value of '1'. The test lasted approximately 9 minutes and number of accurate responses to stimulus was calculated.

    Measured: Baseline to 120 minutes post treatment administration

  2. Change From Baseline in Mean Time of Accurate Responses to RVIP Cognitive Task

    The mean time of accurate responses was defined as the mean reaction time for the correct responses. For records with '1' in the 'CORRECT=1' column, the mean time of accurate response was calculated as the summation of the response time values divided by number of records with '1' in the 'CORRECT=1' column. The result was multiplied by 1000 to convert into milliseconds (msecs).

    Measured: Baseline, 60 minutes and upto 120 minutes post treatment administration

  3. Change From Baseline in Number of Inaccurate and Missed Responses to RVIP Cognitive Task

    The no. of inaccurate responses to RVIP was determined from cognitive function computerised output. Participants monitored a series of single numbers (0-9) appearing in the centre of screen. They responded to consecutive sequences of 3 odd or even numbers by pressing the corresponding response button. This was identified in the output file by a value of '1' in the 'TARGET=1' column. If a subject responded incorrectly to stimuli (pressed the response button at the wrong time), this was identified by a value of '-1' in the 'CORRECT=1' column. The no. of incorrect responses was calculated as the total no. of records where 'CORRECT=1' had a value of '-1'. If the subject missed a target (failed to press the response button within 600 msecs of being presented with a string of 3 consecutive even or odd numbers), this was considered a missed response and was calculated as the no. of records where there was a value of '1' in the 'TARGET=1' column and a value of '0' in the 'CORRECT=1' column.

    Measured: Baseline, 60 minutes and up to 120 minutes post treatment administration

  4. Change From Baseline in Number of Accurate Responses to Sustained Attention Tasks (SAT) Cognitive Test

    Auditory and visual attention of participants was evaluated using a validated Sustained Attention task. For the sustained auditory attention task, participants were required to respond whenever they heard the number '8' in a continuous stream of numbers presented through headphones. This was identified in the output file by a value of '8' in the 'NUMBER' column. For the sustained visual attention task, participants were required to respond to the letter 's' every time it appeared in a continuous stream of letters presented on a screen. This was identified in the output file by a value of 's' in the 'LETTER' column. If the subject correctly responded to the target, this was identified by a value of '1' in the 'CORRECT=1' column. The number of accurate responses was calculated as the total number of records where 'CORRECT=1' had a value of '1'.

    Measured: Baseline, 60 minutes and up to 120 minutes post treatment administration

  5. Change From Baseline in Mean Time of Accurate Responses to SAT Cognitive Task

    The mean time of accurate responses was defined as the mean reaction time for the correct responses. For records with '1' in the 'CORRECT=1' column, the mean time of accurate response was calculated as the summation of the response time values divided by number of records with '1' in the 'CORRECT=1' column. The result was multiplied by 1000 to convert into milliseconds (msecs).

    Measured: Baseline, 30 minutes and up to 60 minutes post treatment administration

  6. Change From Baseline in Number of Incorrect and Missed Responses to SAT Cognitive Test

    For sustained auditory attention task, participants were required to respond on hearing the no. '8' in a continuous stream of numbers through headphones. It was identified in output file by a value of '8' in 'NUMBER' column. For sustained visual attention task, participants responded to letter 's' every time it appeared in a continuous stream of letters presented on screen. This was identified in output file by a value of 's' in 'LETTER' column. If a subject responded incorrectly (pressed the response button at the wrong time), it was identified by a value of '-1' in 'CORRECT=1' column. The no. of incorrect responses was calculated as total no. of records where 'CORRECT=1' had a value of '-1'. The no. of missed responses (when subject failed to press the response button on hearing the number '8' or seeing the letter 's'), was calculated as the no. of records where there was a value of '8' in 'NUMBER' column or 's' in the 'LETTER' column and a value of '0' in the 'CORRECT=1' column.

    Measured: Baseline, 60 minutes and up to 120 minutes post treatment administration

  7. Change From Baseline in Number of Valid Responses to Divided Attention Task (DAT) Cognitive Test

    Auditory and visual attention of participants was evaluated using a validated Divided Attention task. Participants were required to respond whenever they heard the number '8' in a continuous stream of numbers presented through headphones or saw a letter 's' on the screen . This was identified in the output file by a value of '8' in the 'NUMBER' column or by a value of 's' in the 'LETTER' column. If the subject correctly responded to the target, this was identified by a value of '1' in the 'CORRECT=1' column. The number of accurate responses was calculated as the total number of records where 'CORRECT=1' had a value of '1'.

    Measured: Baseline, 60 minutes and up to 120 minutes post treatment administration

  8. Change From Baseline in Mean Time of Accurate Responses to DAT Cognitive Test

    The mean time of accurate responses was defined as the mean reaction time for the correct responses. For records with '1' in the 'CORRECT=1' column, the mean time of accurate response was calculated as the summation of the response time values divided by number of records with '1' in the 'CORRECT=1' column. The result was multiplied by 1000 to convert into milliseconds (msecs).

    Measured: Baseline, 60 minutes and up to 120 minutes post treatment administration

  9. Change From Baseline in Number of Incorrect and Missed Responses to DAT Cognitive Test

    For the Divided Attention task, participants were required to respond on hearing the no. '8' in a continuous stream of numbers through headphones or seeing a letter 's' on screen. This was identified in the output file by a value of '8' in 'NUMBER' column or 's' in 'LETTER' column. If a subject responded incorrectly (pressed the response button at the wrong time), this was identified by a value of '-1' in 'CORRECT=1' column. The number of incorrect responses was calculated as the total no. of records where 'CORRECT=1' had a value of '-1'. If the subject missed a target (failed to press the response button on hearing the no. '8' or seeing the letter 's'), this was considered a missed response. The number of missed responses was calculated as the no. of records where there was a value of '8' in 'NUMBER' column or 's' in 'LETTER' column and a value of '0' in the 'CORRECT=1' column.

    Measured: Baseline, 60 minutes and up to 120 minutes post treatment administration

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jul 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Number of Accurate Responses to Rapid Visual Information Processing (RVIP) Cognitive Test (time frame: Baseline to 60 minutes post treatment administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
