Provide a short summary of the purpose and procedures of the study proposed in this IRB application.
DO NOT include information on studies not proposed in this application.
Use LAY terminology only. This must be easily understandable by IRB community members and nonscientists.
DO NOT cut and paste technical abstracts from funding applications that may not be understood by a general
audience.
The overall study is designed to characterize the effects of common recreationally used prescription drugs (as well as Cannabis) with
well known stimulant and sedating effects (Xanax and Adderall) and their relationship to results from the the Mobile Alertness Memory
Profiler (M-AMP) which includes a set of vigilance and memory tasks. This study will test the effect of Cannabis. The other drugs are
being tested under separate IRB applications. This study will involve twenty subjects completing the protocol with up to twenty-six
enrolled. This will involve testing using EEG, EKG, computerized assessment, blood sampling, and driving simulation.
The studies involve three visits, a screening visit as well as two dosing visits. The dosing visits will have a clean (placebo)and a drugged
visit. The screening visit will last about two hours and will include drug and pregnancy testing as well as screening for
physical/psychological health. Each of the dosing visits will last approximately five to six hours each and will involve baseline M-AMP
assessment, a baseline drive, M-AMP assessment after dosing, a dosed drive, and dosed M-AMP assessment. There will also be blood
sampling before dosing, before driving, and after driving.

application in detecting drug effects that effect driving.
I.6
Background and significance and/or Preliminary studies related to this project.
(do not indicate "see protocol")
Many commonly used drugs including prescription, over-the-counter and illicit affect cognition, judgment, reflexes, and motor skills.
Drug–related impairment while driving increases the potential for injuring others and causing fatalities (Walsh, de Gier et al. 2004). An
estimated 18% of deaths caused by motor vehicle accidents are due to drug use (not including alcohol), and a 2008 survey revealed that
over 10 million people in the US admitted to driving while under the influence of illicit drug (USDHHS 2009). The National Highway
Traffic Safety Administration's (NHTSA) 2007 National Roadside Survey reported that more than 16% of weekend, nighttime drivers
tested positive for illegal, prescription, or over-the-counter medications (NHTSA 2007). The impact of driving while intoxicated is of
greatest concern amongst teenagers in part because they are the least experienced drivers and thus the most vulnerable to the effects of
drugs and alcohol. According to the Centers for Disease Control and Prevention, vehicle accidents are the leading cause of death among
young people age 16 to 19 (CDC 2008).
Marijuana is the most prevalent illegal drug detected in impaired drivers, fatally injured drivers, and motor vehicle crash victims.
Evidence from both simulation-based and real world driving studies reveal that marijuana can negatively affect a driver's attentiveness,
perception of time and speed, and the ability to recall and integrate prior experience. Marijuana has been shown to slow reaction time,
impair concentration, induce sleepiness and may cause blurred vision and visual distortion. Other common drugs implicated most
frequently in DUI arrests and motor vehicle crash victims (in addition to alcohol) belong to one of five classes: tranquilizers (i.e.
benzodiazepines) , opioids, stimulants (i.e. amphetamine, cocaine, methamphetamine, and methylenedioxymethylamphetamine
a.k.a.MDMA or ecstasy), antidepressants and antihistamines (Walsh, Flegel et al. 2004).
Although drugs and alcohol levels can be assessed using breath, saliva, blood, sweat, urine and hair tests, there are currently no devices
for directly assessing the neurocognitive impairments associated with drug ingestion. There is a need for devices that can be easily
administered to assess the behavioral and physiological indices of drug use and the subsequent effect on driving and other task
performance. Today’s ubiquitous smart phone technologies offer a potentially rich platform for data acquisition and analysis with the
benefit of instant connections worldwide. An evaluation test running on a smartphone platform could be used to administer assessments
in the field. Additionally, a mobile evaluation platform would provide a tool for researchers to investigate the substance type and dose
associated with driving related impairment and international comparative studies of drug induced intoxication. The information acquired
from such studies would be invaluable in providing objective data on which to develop legislation and regulation, as well as educating law
makers, insurance and healthcare providers, and consumers on the effects of drug intoxication on driving and other performance.
The proposed work for Phase II addresses this need with the Mobile Alertness and Memory Profiler (M-AMP), a system to be
developed by Advanced Brain Monitoring (ABM) to provide a quantitative assessment of neurocognitive functions including alertness,
attention, and memory. ABM will leverage prior work in developing platform technologies that facilitate high throughput data acquisition
and analysis for human subject studies of brain and behavior. The Alertness and Memory Profiler (AMP) is an inexpensive, non-invasive
solution that combines easy acquisition of EEG, EKG and actigraphy during a simple neurocognitive assessment using a single, integrated
and synchronized system. The AMP approach facilitates rapid data collection from any size population, enabling large scale
epidemiological studies, disease diagnosis, or treatment outcome evaluations. The AMP multivariate approach has been is proven
sensitive and specific in characterizing the drowsiness-alertness continuum (Berka, Levendowski et al. 2005; Berka, Levendowski et al.
2007), discriminating drowsiness associated with sleep deprivation versus that caused by a sleep disorder and in identifying profiles
associated with several commonly used anti-depressant drugs and nicotine. The M-AMP will employ a similar approach, integrating
neural, physiological and performance measures into an easy-to-administer mobile platform.
Previous investigations conducted by ABM and others suggest that the M-AMP human cognition metrics will be highly sensitive to druginduced stimulant and depressant effects. Many studies have evaluated EEG correlates of drug ingestion using EEG recorded from
subjects that were passively resting with eyes closed and/or eyes open. More recent work reveals that EEG recorded concomitantly
with cognitive tasks offers a rich source of data using a combination of EEG and performance metrics derived from the task (Gevins and
Smith 1999; McEvoy, Smith et al. 2000; Berka, Levendowski et al. 2005; Berka, Levendowski et al. 2006; Berka, Ayappa et al.
2009). Multivariate analysis of EEG and performance metrics acquired during vigilance, attention, and memory tasks have been useful in
distinguishing between alertness and drowsiness, mild, moderate and severe cognitive impairment and intoxicated states resulting from
drug or alcohol ingestion (Gevins and Smith 1999; McEvoy, Smith et al. 2000; Berka, Levendowski et al. 2005; Berka, Levendowski
et al. 2006; Berka, Ayappa et al. 2009).
The AMP system initially ran on a PC and acquired data that can be used to establish profiles associated with either stimulant or
depressant drug ingestion providing an estimate of the level of intoxication. In Phase 1, the M-AMP was designed to run on a smart
phone platform to facilitate the collection of epidemiological data on drug use patterns that could be easily applied to roadside
evaluations worldwide.
In Phase 2 the M-AMP will be evaluated in combination with validated driving simulation protocols developed and tested at the
University of Iowa. The team will also explore the utility of the M-AMP determining which substances impair driving-related behaviors
with significantly powered human subject studies.
The current AMP includes: a) easily applied wireless acquisition of EEG, EKG, and optional respiration, GSR, and eye tracking; b)
computerized subjective questionnaires that are autoscored and uploaded to the database; c) two preliminary report outputs; d)
automated data quality evaluation with specific troubleshooting tips (e.g. an electrode needs to be reapplied or excessive EMG is
identified indicating movement). Additional features include: allowing users to adjust AMP protocols and duration, automated self-report
administration, and data quality procedures (60 s signal/artifact and impedance check). Multiple options for monitoring EEG quality were
developed based on customer input, including simplified feedback to identify channels with significant data loss or instructing to restart a
task if there is excessive data loss. Supplemental features include audio alerts, simplified user instructions and practice tests to ensure
training-to-criterion on each of the AMP tasks.
Additional details about the M-AMP tasks are included in the AMP Task Details attachment.

Describe EACH of your subject populations
Include description of any control group(s)
Specify the Inclusion/Exclusion criteria for EACH group
A total of twenty subjects are needed to complete the study. It is anticipated that up to twenty-six will need to be enrolled to reach this target.
Although an equal sample of males and female subject are desired for completing this study, some imbalance will be allowed. Subject progress
will be tracked via an accountability spreadsheet. Recruitment effects will be modified based on the number of each gender enrolled and the
number of each gender completed. For example, if five male subjects and only two females subjects have completed, recruitment efforts will be
focused primarily on females.
No control group will be used for this study.
Inclusion Criteria:
Men and women 18 to 40 years of age in good health
Valid US driver's license and have been licensed driver for two years
Restrictions on driver's license limited to vision correction only
Drive at least 5,000 miles per year
Must be able to attend two morning daytime study visits lasting approximately 5 to 6 hours.
Live within 1 hour driving radius of NADS
Subjects must be users of cannabis(marijuana)of at least once every three months and no more than three times per week.
Exclusion Criteria:
Females who are pregnant or test positive for pregnancy or lactating.
Any known sleep disorders, or family history of sleep disorders
Any neurological or pulmonary disorders (or taking medications for such)
Any psychiatric disorder (or taking medications for such)
Any eating disorder
Diagnoses of myasthenia gravis, glaucoma, or cirrhosis of the liver

above)
VI.14
Provide an estimate of the total number of subjects that would be eligible for inclusion in each of your study populations
(include your control population if applicable)
There are approximately 133,000 people that reside in Johnson County Iowa. It is estimated that approximately 45% of the population is
between the ages of 18 and 40. This would give us approximately 60,000 people in Johnson County that would be eligible for participation.
Taking into account the inclusion and exclusion criteria, even if 75% were not eligible, that would still leave a study population from which to
recruit of 15,000 which would provide a sufficient population from which to recruit.
Additionally, we will focus additional recruitment efforts in the Cedar Rapids Metropolitan Area(258,000), the Davenport-Moline-Rock Island
Metropolitan Area (381,000), and in West Liberty (3,750). Assuming similar age and eligibility estimates as used for Iowa City, this would add
another 72,000 from the population from which we will be recruiting.
VI.15
Describe how you will have access to each of your study populations in sufficient number to meet your recruitment goals.
The primary recruitment tool to access the study population required for the main study will be the NADS database. A database query of the
prospective age groups of people will be completed. From this query, a list of names will be generated. Emails will be sent out with study
information to those with valid addresses while others will be called. Phone screenings will be conducted to determine if potential subjects meet
study criteria.
In an effort to recruit a variety of racial/ethnic groups for this study, efforts will be focused in several ways to improve enrollment:
1) An intensive recruitment effort in larger population centers within a 1 hour drive to the research facility (Davenport, IA and Cedar Rapids,
IA) which have more diverse demographics
2) An effort to recruit in a population area known to have a higher concentration of a particular ethnicity (West Liberty, IA)
3) A direct appeal to adult associations of certain ethnicities
a. Latino Service Providers
b. Iowa Asian Alliance
c. Iowa Chapters of the NAACP

identify potential subjects, the study coordinator will discuss the study with subjects over the telephone and schedule the
first study visit, etc...”
Describe the steps that will be taken by the research team to minimize the possibility of coercion or undue influence during
the consent process
This study does not involve a control group. The study population consists of healthy men and women ages 18-40, gender balanced, and meet
the study inclusion/exclusion criteria.
Prospective subjects will be identified using the NADS participant database and outreach to underrepresented populations. An approved email
will be sent to eligible subjects or contacted via telephone. Potential subjects will have access to websites that can be used to show their
interest: www.drivingstudies.com and www.nads-sc.uiowa.edu. Both sites will have approved website script located on website. The
approved email will be sent to UI faculty and staff and students if other measures do not meet study requirements. Additionally, fliers will be
distributed to help increase minority enrollment.
Once subjects have expressed interest in participating, they will be recruited via phone and, we, the study staff, will inform the subject of the
study procedures and time commitment. Then, we the study staff, will determine if the potential subject meets initial study criteria by asking the
inclusion/exclusion criteria questions over the phone. These questions ask potential subjects about their driving qualifications, health history,
current health status, medications used (MSD_Screening Procedures). Answers from the Screening Procedures will not be recorded except
the question asking the potential subject about their susceptibility to motion sickness which could exclude them from participating in the study. If
subject meets the inclusion/exclusion criteria, we, the staff will appoint subject for study visit. A copy of the approved Informed Consent
document will be available to subjects if requested prior to first study visit when consent will be obtained.
We, the study staff, will consent subjects at The National Advanced Driving Simulator, located on the UI Research Park. We, the study staff,
will verbally explain the purpose and procedures involved in the study and answer questions subjects may have about their participation.
Following verbal review of the informed consent, the subject will be asked to thoroughly read the informed consent document and we, the
study staff, will answer any further questions about the subject's participation in the study. Ample time will be allowed for subjects to ask
questions to us, the study staff, about the study and their participation. The subject will be considered enrolled into the study once they have
signed the Informed Consent Document. A copy of the signed informed consent document will be provided to each subject and the original will
be maintained by NADS.

DESCRIBE:
What subjects will be asked to do/what happens in the study (in sequential order)
The time period over which procedures will occur
The time commitment for the subject for individual visits/procedures
Long-term followup and how it occurs
Subjects will be asked to complete 3 study visits, one screening visit of approximately 2 hours in length, two daytime study drive visit
approximately 5 to 6 hours in length starting at 8:00 am.
Screening Visit
Subjects will first complete a screening visit. Participants will be asked to provide a urine sample and a urine drug screen test will be
performed. Female subjects’ urine specimen will additionally be tested and screened to determine if they are pregnant. Results from the drug
screen, and for females, pregnancy test will remain confidential and their eligibility status will be documented as either a yes or no. Subject
participation will end if their drug screen test is positive, and if female, they test positive for pregnancy. Subjects height and weight will be
recorded. A questionnaire that asks questions about demographic information, their driving record, driving behavior, and driving history
(MSD_DrivingSurvey) will be completed. Subjects who fail to meet study criteria, will be paid for their time and effort. If subject meet criteria,
subjects will watch an overview presentation of the simulator cab and staff will train them on an in-vehicle tasks. Subjects will drive the
simulator for about 5-8 minutes. This drive allows the subjects a chance to become comfortable with driving the simulator. After the practice
drive, subjects will fill out a questionnaire about how they feel(MSD_Wellness). If the MSD_Wellness indicates a high propensity for simulator
sickness, subjects will be excluded from continuing in the study and paid for their time and effort. If they can continue, subjects will have the BALERT® EEG Wireless Sensor Headset (MSD_B-alert X-10.pdf) that wirelessly records brain activity for nine channels, and ECG from
leads placed on the lower left chest and right collarbone. They will then complete a 45 minute Mobile Alertness Memory Profiler (M-AMP)
Assessment, which involves three tests. The first is a multiple choice vigilance task that requires the subject to identify a predetermined target
from amongst three objects. The second is task is divided into and eyes open task and an eyes closed task. The eyes open task requires the
subject to press a button each time an image appears on the screen. They eyes closed task requires the subject to press a button each time you
hear an auditory tone. The third task is an image recognition task in which the subject will be presented a set of images and then asked to
indicate whether images from another set were in the original set they were shown. Then staff will confirm the next two study visits and ask
subjects to arrange for third party transportation to and from NADS on both study visit days. In the event that the subject cannot arrange for
third party transportation, taxi transportation or transportation by NADS staff will be arranged by study staff at no cost to the participant.
Study Visits:
On arrival, staff will first collect a urine sample to test for illicit drug use and pregnancy. Subjects will then complete a sleep and food intake
questionnaire (MSD_SFI) and will also complete a questionnaire about their current sleepiness level (MSD_SSS). If subject meets study
criteria (had 7-9 hours of sleep) a baseline 4mL blood sample will be obtained by a medical professional using an individual needle poke.
Subjects will then be fitted with the B-ALERT® EEG Wireless Sensor Headset (MSD_B-alert X-10.pdf). This device is a non-intrusive
wireless recording device that is worn on subjects' head. After being escorted to the prep room, the subject will be administered a single dose
of Cannabis with a target concentration of (6.7% THC), or a placebo via inhalation, and rest for 30 minutes before completing the M-AMP
assessment. A medical professional will obtain a second blood sample of 4 ml by individual needle stick. The subject will be asked to complete
the Stanford Sleepiness Scale (MSD_SSS) questionnaire again about their current sleepiness level. The subject will be escorted to the
simulator where any questions will again be answered. The subject will complete a 35 minute drive. The study drive consists of 3 segments,
each 10 minutes in length which includes urban, freeway, and rural roadways. After the drive subjects complete questionnaires about how they
feel (MSD_Wellness) and about the simulator (MSD_Realism). A third and final blood sample of 4 ml will be obtained by the medical
professional via individual needle poke. The blood samples will later be analyzed to assess the pharmacokinetics of the drugs relative to each
participant. If this is the second visit, the date for the final visit will be confirmed. If it is the third visit, payment will be finalized.
No follow-up for this study.
The driving trials will be recorded using a digital video tapes/camera that will record the driver and the drivers interaction with the simulator.
The video will play a role in verifying reduced simulator data. The video will not be destroyed but will be stored in locked archive room along
with other data.

VIII. Risks
VIII.1
What are the risks to subjects including
- emotional or psychological
- financial
- legal or social
- physical?
The risk involved driving the simulator is possible discomfort associated with simulator disorientation. Previous studies with similar driving
intensities and simulator setups have produced few disorientation effects. When effects were reported, they are usually mild to moderate and
consisted of slight uneasiness, warmth, or eyestrain for a small number of subjects. These effects are believed to last for only a short time,
usually 10-15 minutes, after leaving the simulator. Subjects may quit driving at any time if they are experiencing any discomfort.
Side effects associated with the study medications may include:
The amount of cannabis which a subject inhales during the study is consistent with typical use. It is expected that subjects could experience
euphoria and dysphoric reactions, including anxiety and panic, paranoia and psychosis. Perceptual changes, including distorted perception of
space and time and hallucinations are also possible. Cognitive and psychomotor effects of cannabis may include slowing of reaction time, motor
incoordination, deficits in short-term memory, difficulty in concentration and impairment in complex tasks that require divided attention. Doserelated tachycardia reaching rates of 160 beats per minute or more are possible, as is widespread vasodilation with reddening of the
conjunctivae. Postural hypotension and fainting may also occur.
Blood Draws: The risk of blood sampling is pain, tenderness, bruising, or bleeding at the needle puncture site, and transient lightheadedness or
dizziness.
The EEG device uses a gel that will be applied to subject's scalp. Some people find this to be uncomfortable or inconvenient as it needs to be
washed out of the hair after the study.
Loss of confidentiality is always a risk.
May test positive for cannabis for 4-5 days after each study visit.
VIII.2
What have you done to minimize the risks?
If applicable to this study ALSO include:
How you (members of your research team at Iowa) will monitor the safety of individual subjects.
Include a description of the availability of medical or psychological resources that subjects might require as a
consequence of participating in this research and how referral will occur if necessary (e.g. availability of emergency
medical care, psychological counseling, etc.)
If a subject asks to quit driving as a result of discomfort, they will be allowed to quit at once. If a subject does quit driving due to discomfort,
they will be escorted to a room, asked to sit and rest, and offered a beverage and snack. A trained staff member will determine if and when the
subject will be allowed to leave. If the subjects shows few or no signs of discomfort, they will be transported home. If the subject experiences
anything other than slight effects, a follow-up call will be made 24 hours later to ensure the subject is not feeling ill effects.
Female subjects who participate in the study will be required to provide urine for a pregnancy test and at phone screening it will be suggested
to all females that if it is possible that they may be pregnant they should not enroll into this study.
To protect confidentiality, subjects will be consented in a private room and study procedures will occur in private. Additionally, the
investigators have requested a certificate of confidentiality from the Department of Health and Human Services.
For the medications, dosage is consistent with general use and staff and subjects will be monitored for side effects during their visits.
VIII.3
Does this study have a plan to have an individual or committee review combined data from all subjects on a periodic basis (such
as summary or aggregate safety and/or efficacy data)?
No
IX. Benefits
IX.1
What are the direct benefits to the subject (do not include compensation or hypothesized results)?
A subject may not benefit personally from being in this study. However, many subjects find driving the simulator of this type to be an exciting
and unique experience.
IX.2
What are the potential benefits to society in terms of knowledge to be gained as a result of this project?
It is hoped that in the future, other people might benefit from this study because the information gathered in this research study might benefit
society from obtaining a better understanding of how to detect drugs being used by drivers. This may allow the development and refinement of
new technologies that could minimize drugged driving related crashes in the future.
X. Privacy & Confidentiality
X.1
What are you doing to protect the privacy interests of the subjects?
Subjects will be escorted into a private room for the consent process. All study procedures prior to and after completing simulator drive(s) will
take place in a private room. All research staff involved in data collection have received certification in the human subjects protection education
program. The researchers will only ask questions related to the study and will collect minimum private information needed to answer the
research questions.
X.2
Are you collecting the Social Security Number of any subjects for any purpose?

How will information/data be collected and stored for this study (check all that apply):
Paper/hard copy records (hard copy surveys, questionnaires, case report forms, pictures, etc.) - Paper/hard copy records (hard copy
surveys, questionnaires, case report forms, pictures, etc.) - Participants will be assigned a research number that staff will use during data
collection, analysis, and reporting. Data, paper and biological samples wil use the participant's research number. Study documents
identifying the participants to their research number will be kept in a locked cabinet within a secure building that can only be entered by
personnel with a marlock key during data collection and analysis. After completion of analysis, all hard copies except the Informed
Consent Documents will be scanned, placed on a CD and placed into the NADS archival room that has limited access by designated
archival personnel. The original Informed Consent Documents will be stored in the NADS archival room that has limited access by
designated archival personnel.
Electronic records (computer files, electronic databases, etc.) - Electronic records (computer files, electronic databases, etc.) -
Electronic study data is collected and recorded onto data storage media and will be password protected and can only be accessed by
investigator, study personnel, or system administrator. All videotapes and questionnaires will be locked in filing cabinets during the data
analysis phase and will only be accessible by study personnel. Data will be transferred to a permanent data storage area at the end of the
project where it will only be available to the funding agency, principal investigator, or research team members. Simulator data is captured
and initially stored on a mirrored RAID system located within a limited access area of the NADS facility. This data is behind a hardline
firewall. Access to study data is controlled through validated user login, authentication protocols and access permissions established on a
per-study basis. Data backups are maintained as dual copies on physical hard drive devices. One drive is stored within a secured
location on-site, and the other is stored off-site under the auspices of The University of Iowa Information Technology Services. All
backup drives are inventoried and access to study data requires a request for access and authorization from a designated authority.
Some surveys are designed and data collected on-line via Qualtrics. The information is saved in a password protected account on their
website. Data is downloaded by UI project staff and saved on the password protected computer located at NADS. Access to our
account is password protected and only the team (or Qualtrics staff only at our request) can access the survey to view or export the
data. Once the survey has closed, all subject identifiers will be removed before the data is exported. The exported survey data will be
stored in a separate file than the subject key. Only the members of the research team will have access to the locally stored subject key
which will be saved in a password protected directory.

Biologic samples (blood draws, check swabs, saliva samples, tissue samples, etc.) - Biologic samples (blood draws, check swabs,
saliva samples, tissue samples, etc.) - Urine specimens will be collected using a sterile lidded container. After specimen has been
screened, the extra urine will be discarded in toilet and sample container will be resealed and disposed into a leak proof plastic waste
bag in a covered biological waste container and trained staff will dispose daily. Safe biohazardous material transport through a public
area is required to prevent spills and accidental exposure. Biological specimens include, blood, plasma, serum, urine, sputum, other body
fluids, biopsy tissue etc. Listed below is how this will be accomplished. Specimen to be transported must be identified by study with a
label. It should be signed out by the transporter from the point of origin. 1. Place specimen in a primary container (blood tubes or conical
tubes, for example) secured with a tight-fitting cap, Parafilm, or tape. 2. The primary container should be labeled with its contents. If the
primary container is not labeled, documentation of the contents should be taped to the outside of the secondary container or placed
inside of it. 3. Place the primary container in a secondary container with an absorbent paper towel or wipe to cushion the primary
container and to absorb liquids in the event of a leak or spill. Acceptable secondary containers include plastic containers or sealable (zip
lock) bags. The bag containing the primary container should be clearly marked “biohazard.” 4. The secondary container (containing the
primary container) should be placed in an external carrier container. The external carrier must be labeled with a biohazard symbol and
the labs contact information. The external carrier container should have an additional absorbent paper towel or wipe to cushion the
secondary container and to absorb liquids in the event of a leak or spill. Upon receipt of sample it should be signed in and stored
properly documenting its location within the lab. Biological samples will be transported to the College of Pharmacy where it will be
stored in a locked storage facility for analysis. Extra blood will be discarded, duplicate serum samples will be obtained, and one aliquot
used for analysis, the other for a backup. The backup sample will be maintained at -70°C in room S435 Pharmacy (Dr. Murry's
Laboratory) until after study publication, then discarded.

Describe
Data will be shared with the sponsor. This data will include a full deidentified data set including the raw data files from EEG data.
Reduced simulator data in an Excel spreadsheet will be shared along with coded survey data. No identifiable information linking the
subject to the data will be shared with the sponsor. Data transfer will occur through the NADS password protected file exchange
system.
XI. Data Analysis
XI.1
Describe the analysis methods you will use, including, if applicable, the variables you will analyze
A variety of driving performance measures including speed, lane keeping, time to collision, and gap acceptance will be analyzed using the SAS
general linear models procedure to verify differences in driving performance between the treatments. The planned method will be to calculate
difference scores between the dosed and baseline drive for each day and to then compare changes in performance associated with the study
drugs.
Driving data will also be correlated with data from the M-AMP (including reaction time and accuracy) and Stanford Sleepiness Scale.
Peripheral venous whole blood is collected from participants for analysis on three occasions on each visit –before dosing, before driving, and
after driving. Blood levels for the drugs in question will be quantified.
A 3 (Drug) X 2 (Clean vs. Drug) ANOVA will also be conducted on variables found in the step-wise regressions within each study.
Finally, step-wise discriminant function and other algorithm development approaches will be explored to delineate between stimulant,
depressant, and normal baseline state.
XI.2
Provide the rationale or power analysis to support the number of subjects proposed to complete this study.
This study has a within subject design so that control vs drug driving performance can be compared. Based on prior research, we expect
driving performance as measured by Standard Deviation of Lane Position to be 1.015 ft. We would hope to detect a 10% change in this
measure. In review of the data, we expect the variability in the difference across subjects to be 0.1269. A sample of 20 would provide a
power of 0.92 for a two-side paired t-test.
