About this study
This project aims to investigate the effect of modafinil on motivation, creativity, cognitive performance, and subjective wellbeing in healthy participants. The main task for this research project is to address how this novel stimulant acutely influences motivation, divergent and convergent thinking, cognitive performance and subjective wellbeing in non-sleep deprived healthy young adults.This is a randomised between-subjects parallel group design study.
Based on the hypothesis that psychostimulants might enhance creativity through the increase in of dopamine and executive planning in healthy adults , we predict that healthy individuals who are in the modafinil condition will perform better in the motivation, creativity, and the cognitive performance tasks. Furthermore, based on the evidence that modafinil increases dopamine in the nucleus accumbens, putamen and the caudate, we expect specific subjective well-being and pleasure enhancement associated with modafinil use in healthy young adults.
Read the detailed description
Detailed Description:
Sixty Four healthy participants will attend one session at the Wellcome Trust Clinical Research Facility (WTCRF) during which they will be tested on objective measures of divergent and convergent thinking tasks, a computerised neuropsychological battery including tasks of motivation, and on well validated questionnaires about subjective wellbeing and salience of pleasure. Participants will be randomly allocated to one group and will receive either one dose of modafinil (200mg) or a placebo prior to testing.
Participants Sixty-four healthy volunteers will be identified via the City of Cambridge participant panel, and via local advertisements. Participants between the ages of 18-40 years will be chosen to avoid any effects of cognitive decline. The larger age range will be chosen to be representative of a wide range of ages and socio-economic statuses. A chartered psychologist will screen all volunteers.
After participants are assessed by the team, they then will complete a baseline physiological measures (blood pressure and pulse) and the National Adult Reading Test (NART) which calculates pre-morbid IQ estimates and matches participants' level of verbal IQ. Participants will then be given a single oral dose (200 mg) of modafinil or placebo with a small glass of water. They will then be asked to rest in a quiet room. Two hours post-drug administration, participants will also complete the computerised neuropsychological battery including the motivational reinforcement cue task and the salience of pleasure task in the form of visual analogue scale (VAS) on a computer screen. The VAS will measure the subjective pleasure gained from completing the computerised tasks and in participating in the study. After the completion of the study, participants will be debriefed by the researcher and will be discharged by a research nurse.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ModafinilDrug
Also called Modafinil:
Modafinil (2-[(Diphenylmethyl) sulfinyl]acetamide (Provigil, 1997)) is a novel drug which has a demonstrable efficacy in the treatment of daytime sleepiness associated with narcolepsy (Benerjee et al., 2004). Studies on healthy volunteers show that modafinil improves neuropsychological task performance in some healthy individuals (Turner et al., 2004; Baranski et al., 2004; MÜller et al., 2004; Randall et al., 2005) and in patients with neuropsychiatric disorders (Minzenberg \& Carter, 2008).
PlaceboDrug
Also called Drug: Placebo
| Study group | Role | What they receive |
|---|---|---|
| Placebo | Experimental | Placebo: study participants received, in a double blind fashion, either a single dose (100 mg) of modafinil or a placebo pill identical to the drug.
Other Names: Placebo. Receives: Drug: Placebo |
| Modafinil | Experimental | Study participants received, in a double blind fashion, either a single dose (200 mg) of modafinil or a placebo pill identical to the drug.

What is being measured
The primary outcome is the main question the study is designed to answer.
Neuropsychological measures
The cognitive measures used in this work will be drawn from the Cambridge Neuropsychological Test Automated Battery (CANTAB) battery and the from the Cued Reinforcement Reaction Task (CRRT):
Participants will be assessed on the computerised neuropsychological tests and subjective questionnaires 2 hours post drug administration for 2 hour period in one study session. Outcome measures are: Errors made by the participant, the number of trials required to locate the pattern(s) correctly, memory scores, and stages completed and strategy score. The percentage of correct trials and latency (speed of participant's response) will be calculated. For the span, scores for both the forwards and backwards tests were summed to yield an overall span score.
For the CRRT participants' responses and reaction times will be recorded. Mean change in Subjective Well-being and subjective pleasure between 1, 2, 3, 4 hours will be calculated.
Measured: 2 hours post drug administration
Secondary outcomes (1)
Physiological measures
Blood pressure and pulse measurements will be taken using a Criticare Systems Inc. Comfort Cuff (Model 507NJ) at five time points: immediately upon arrival, before drug administration, immediately prior to testing (2 h post-drug), 1 h into testing (3 h post-drug), and on completion of the study (4 h post-drug). To monitor adverse events, this will measure number of participants on active and non-active agent with high or low blood pressure and plus. Outcome measure: Change from Baseline in Systolic Blood Pressure at Hour 1, 2, 3, and 4.
Measured: Baseline and hourly observation for 4 hours

Questions about this trial
What is this clinical trial studying?
A study testing Modafinil in people with Cognitive Performance and Creativity, run by Cambridge University Hospitals NHS Foundation Trust at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Jan 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Neuropsychological measures (time frame: 2 hours post drug administration). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02051153, which also lists 7 linked publications.
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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Jan 2014.
