Brief summary:
This study aims to recruit 40 participants who will take the combination anti-HIV drug tenofovir+emtricitabine (TDF/FTC) at specified times. Participants will then provide biologic samples for the measurement of anti-retroviral drug concentrations in various body compartment sites. Participants will be involved in the study for up to 24 weeks.

Detailed description:
Men who have sex with men (MSM) continue to be disproportionately affected by HIV. In 2014, MSM made up approximately 2% of the U.S. population but accounted for 70% of the new HIV infections. The majority of MSM acquire HIV after exposure to the rectal mucosa through receptive anal intercourse without condoms. Pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are recommended for MSM who may be exposed to HIV to prevent infection. Current recommendations for PrEP are to take the combination anti-HIV drug, tenofovir+emtricitabine (TDF/FTC), on a daily basis for the duration of someone's HIV risk exposure period, which could be months or years. For PEP, a three-drug anti-HIV medication is recommended within 72 hours of a possible exposure for a 28-day course. While PrEP and PEP are effective, some people find it difficult to follow the recommended regimen. Therefore, additional short-course dosing regimens for PrEP and PEP are being implemented, such as on-demand or event-driven PrEP (ED-PrEP). This dosing regimen has patients take two doses of PrEP 2 to 24 hours before sex, one dose 24 hours after sex, and another dose 48 hours after sex. This study seeks to evaluate the usefulness of biomarkers to confirm self-reported adherence to ED-PrEP in MSM. The study drug provided in this study will not protect participants from HIV or treat any active infection.

This study will recruit 40 HIV-negative MSM aged 18-59 in good general health. Participants will be sequentially assigned to one of four study arms which will determine when they will take doses of the study drug and give specimen samples. All participants will provide written informed consent at the first study visit and undergo a screening medical history, physical exam, and safety laboratory tests. All participants will take at least 4 doses (pills) of the study drug. At study visits, participants will return to donate blood, hair, and urine samples, and a finger stick. All biologic specimens collected will be transferred to the Centers for Disease Control and Prevention (CDC) on the day of collection for measurement of drug levels.

Arms: arm 1: The first 10 participants (Arm A) will take TDF/FTC for three consecutive days of one week, taking 2 pills on the first day and one pill on the second and third day, for a total of 4 doses. arm 2: The second 10 participants (Arm B) will take TDF/FTC for three consecutive days for thirteen weeks, taking 2 pills on the first day and one pill on the second and third day of each week, for a total of 52 doses. arm 3: The third 10 participants (Arm C) will take TDF/FTC for three consecutive days, alternating weeks over a 13-week period, taking 2 pills on the first day and one pill on the second and third day of each dosing week, for a total of 28 doses. arm 4: The fourth 10 participants (Arm D) will take TDF/FTC for three consecutive days over a 13-week period, alternating two weeks of study medication followed by two weeks with no medication, taking 2 pills on the first day and one pill on the second and third day of dosing each week, for a total of 28 doses.
Interventions: intervention 1: Tenofovir disoproxil fumarate/emtricitabine (TDF/FTC)
Intervention descriptions: intervention 1: TDF/FTC is a combination anti-HIV medication that contains the drugs tenofovir disoproxil fumarate (300 mg) and emtricitabine (200 mg). Participants will take 2 pills on the first day of the week and one pill per day on the second and third days of the week, according to the dosing schedule of the study arm they are in. Participants will have biologic specimens collected at specific time points until 28 days after the last dose.

Rationale: Men who have sex with men (MSM) continue to be disproportionately 
affected by HIV. The majority of HIV infections among MSM occur through exposure to 
the rectal mucosa during condomless receptive anal intercourse (CRAI). To aid in 
prevention, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are 
recommended for MSM who may be exposed to HIV. Current CDC recommendations 
for PrEP are to take the combination anti-HIV drug, tenofovir+emtricibatine (TDF/FTC), 
on a daily basis for the duration of someone’s HIV risk exposure period, which could be 
months or years. For PEP, a three-drug anti-HIV medication is recommended within 72 
hours of a possible exposure for a 28-day course by CDC. While PrEP and PEP are 
efficacious, both the daily dosing of PrEP and the 28 day course of PEP limit their utility 
in practice, as many users find long term adherence to these regimens to be difficult. 
Therefore, short course regimens taken around the time of sex (On-demand or Event-
Driven PrEP; ED-PrEP) are appealing to some, and WHO endorses one such ED-PrEP 
regimen: two doses of TDF/FTC between 2 and 24 hours before sex, one dose 24 
hours after sex, and another dose 48 hours after sex. Biomarkers (e.g. tenofovir 
diphosphate (TFV-DP) levels from dried blood spots) to confirm self-reported adherence 
to daily TDF/FTC have been an important tool used to interpret the results of PrEP 
clinical trials and demonstration projects. However, no such biomarkers exist to validate 
self-reported adherence to ED-PrEP. The aim of this study is to better understand how 
biomarkers might be used to validate self-reported ED-PrEP use. As ED-PrEP is 
intended to be used infrequently, this study will determine if the accumulation of 
biomarkers differs depending on whether multiple ED-PrEP dosing events are 
sequential or intermittent.  
Design: To establish biomarkers to determine adherence of ED-PrEP in MSM, 
investigators at Emory University will collaborate with the Center for Disease Control 
and Prevention (CDC) to conduct a clinical trial of up to 40 MSM aged 18-59 with 
measurement of anti-retroviral drug concentrations in various body compartment sites. 
We plan to enroll participants who are HIV negative and at low risk for HIV and are not 
currently (or have no current plans) taking PEP or pre- exposure prophylaxis (PrEP). 
We will enroll participants in one of 4 study arms where they will be given the 
aforementioned 2-1-1 dosing of TDF/FTC. 
We will recruit participants through existing research databases at the Hope Clinic and 
the Rollins School of Public Health, Research Match, and Clinical Data Warehouse. 
Internet and paper advertisements, and community venues will also be used. At the first 
study visit, eligibility will be determined and screening blood work (approximately 24 
mL), including an HIV test, will be performed. Participants will receive doses of the drug 
in clinic or will provide documentation of taking doses of the drug at home. During 
visits, all participants will undergo blood collection (approximately 24 mL or 5 teaspoons 
of blood will be obtained), a urine sample, and finger stick will be collected. At certain 
visits, hair sampling will also be collected.

Duration: The duration of this study is 1 year. Participants will be considered ‘on study’ 
for no more than 24 weeks.
Sample Size: For this protocol we will recruit 80 HIV-negative MSM (age 18-59) who 
meet eligibility criteria outlined in the protocol, to ensure completion of 40 participants.
Population: The population to be studied in this protocol are healthy HIV negative MSM 
at low risk of HIV infection who currently do not desire daily PrEP and are willing to 
perform study procedures. We will recruit participants through existing research 
databases at the Hope Clinic and the Rollins School of Public Health, through internet 
and paper advertisements, and community venues as is currently the process for Dr. 
Kelley’s ongoing research protocols.
LAY SUMMARY:
Men who have sex with men (MSM) continue to be disproportionately affected by HIV. 
In 2014, MSM made up approximately 2% of the U.S. population but accounted for 70% 
of the new HIV infections (CDC)(2). The majority of MSM acquire HIV after exposure to 
the rectal mucosa through receptive anal intercourse without condoms. Pre-exposure 
prophylaxis (PrEP) and post-exposure prophylaxis (PEP) are recommended for MSM 
who may be exposed to HIV to prevent infection. Current recommendations for PrEP 
are to take the combination anti-HIV drug, tenofovir+emtricibatine (TDF/FTC), on a daily 
basis for the duration of someone’s HIV risk exposure period, which could be months or 
years. For PEP, a three-drug anti-HIV medication is recommended within 72 hours of a 
possible exposure for a 28-day course. While PrEP and PEP are effective, some people 
find it difficult to follow the recommended regimen. Therefore, additional short-course 
dosing regimens for PrEP and PEP are being implemented, such as event-driven or on-
demand PrEP (ED-PrEP). This dosing regimen has patients take two doses of PrEP 2-
24 hours before sex, one dose 24 hours after sex, and another dose 48 hours after sex. 
This proposal seeks to evaluate the usefulness of biomarkers to confirm self-reported 
adherence to ED-PrEP in MSM. The study drug provided in this study will not protect 
participants from HIV or treat any active infection.
For this protocol, we will recruit 80 HIV-negative MSM aged 18-59 in good general 
health. Participants will be sequentially assigned to one of 4 study arms which will 
determine when they will take doses of the study drug and give specimen samples. All 
participants will provide written informed consent at the first study visit and undergo a 
screening medical history and safety laboratory tests. A physical exam may also be 
completed. All participants will take at least 4 doses of the study drug. At study visits, 
participants will return to donate blood, hair, and urine samples, and a finger stick. All 
biologic specimens collected will be transferred to CDC on the day of collection for 
measurement of drug levels.

PROJECT DESCRIPTION
Public Health Relevance: Event-driven PrEP (ED-PrEP) could be an effective solution 
for those who struggle to take a daily regimen of PrEP to prevent HIV. This is 
particularly important for those who engage in sexual activities less regularly, and 
therefore feel daily PrEP is unnecessary or too costly. However, there are currently no 
biomarkers available to validate self-reported ED-PrEP adherence.
Goal: The goal of this study is to evaluate the utility of biomarkers to validate self-
reported ED-PrEP dosing.

PROCEDURES
Recruitment procedures
Participants will be recruited with several methods.  First, the Hope Clinic maintains 
large databases of potential participants interested in participating in future research.  
Email blasts and phone calls will be made to potential participants from these 
databases.  ResearchMatch, a secure online database used by researchers who are 
seeking volunteers and people who are interested in finding research/ clinical trial 
studies to participate in, will also be used as a recruitment source.  The site will recruit 
from the Emory Healthcare Clinical Data Warehouse. The Clinical Data Warehouse is a 
repository that integrates data from clinical applications within Emory Healthcare, 
providing data needed for clinical reporting, research and operational support.  Any 
contact made by email and or phone (refer to online engagement section for direct & 
SMS messaging script), recruiters will use one of the following scripts:
Phone call
Participants who are called will be greeted by the study staff. “Hello, my name is [        ]. 
I am calling from the Hope Clinic…” Staff will refer to Oral Consent and Pre-Screener.
Email
Hello my name is [         ] and I am from Emory University Hope Clinic. We are currently 
looking to enroll participants into a new study at the Emory University Hope Clinic. This 
study aims to establish biomarkers to determine adherence to on-demand PrEP which 
can be used to effectively prevent HIV. Study visits range from ten to twenty two visits, 
and you will be compensated for your time of travel and inconvenience. If you or anyone 
you know may be interested or have any questions about this study, please contact 
___________ or ___________. These are the basic qualifications to participate in the 
study:
You may qualify if you are:
Age 18-59
HIV negative man who has sex with men
Not currently taking PrEP or PEP
Able to consistently use condoms
Print and on-line ads will also be placed around Emory and other community settings.  
Finally, active recruitment will be conducted as outlined below with face-to-face and 
online engagements. Dr. Kelley and co-investigators have a successful track record in 
recruiting MSM for their research protocols utilizing all of these methods.     
Volunteer contact details are collected by conducting in person face-to-face and/or 
online social network engagement.

Online engagements: Potential participants will be engaged and supplied with limited 
information about the study and study qualifications via paid advertisements on social 
media sites and dating apps. All print and online advertisement copies will be submitted 
to the Emory IRB for approval prior to launching these activities. Interested participants 
will click a posted ad with an embedded hyperlink, which will redirect them to a short 
screener. This screener will capture information regarding eligibility, including HIV 
status, name, phone number and email. Recruiters will use information obtained from 
online screener to contact and schedule participant visits. Potential participants may 
also be engaged directly on social media to assess interest in research participation. 
Any contact made through direct messaging, recruiters will have a generalized script 
(mentioned below) to follow (script can also be used for SMS contacting, as well).  We 
will seek permission from creator/ moderator of the private website/ group, etc. before

Participants may participate in more than one study arm; however, at least 8 weeks 
must lapse after completion of one study arm, before entry into another. Participants 
who participate in more than one arm do not have to repeat the screening visit (visit 1) 
when starting another arm; they will begin the new arm at visit 2. However, they will be 
re-consented on the consent form of the new arm prior to any arm-specific study 
activities being performed. 
Participants who are unable to donate hair will not be considered protocol deviations.
The consent process will be conducted in a private exam room at the Hope Clinic or 
electronically via an online e-consent platform. Copies of the consent form for this 
project will not be placed in individuals’ medical records since this study collects 
sensitive information such as HIV status and sexual orientation.  All participants will be 
provided a copy of the signed informed consent form (ICF).
ARM A (n=20; Arm will close to enrollment once 10 participants have completed 
study visits):
Visit 1 (screening): Eligible MSM will be questioned about their medical history, 
undergo an HIV test, and a peripheral blood sample for creatinine and hepatitis B 
testing, as well as testing for baseline levels of study drug. A physical exam may also be 
completed. Participants will then be asked to return within 1-6 weeks for visit 2. 
Visit 2: Participants will return to the clinic to be given their first dose of 2 pills of 
TDF/FTC with instructions to take the next pill 24 hours later, and document that dose 
with a time-stamped photograph or video.
Visit 3: Participants will return to the clinic 48 hours after first dose, and 24 hours after 
second dose to receive their third and final dose of one pill. After the dose is taken, 
approximately 24mL of blood will be drawn, urine sample, and a finger stick will be 
collected. 
Visit 4: Participants will return to the clinic 24 (+/- 2 hrs) hours after their last dose at 
Visit 3. Approximately 24mL of blood will be drawn, urine sample, and a finger stick will 
be collected.
Visit 5: Participants will return to the clinic 2-5 days after their last dose at Visit 3. 
Approximately 24mL of blood will be drawn, urine sample, and a finger stick will be 
collected.
Visit 6: Participants will return to the clinic 7 (+/- 1 day) days after their last dose at Visit 
3. Approximately 24mL of blood will be drawn, urine sample, and a finger stick will be 
collected.

be collected.
Visit 8: Participants will return to the clinic 21 (+/- 1 day) days after their last dose at 
Visit 3. Approximately 24mL of blood will be drawn, urine sample, and a finger stick will 
be collected.
Visit 9: Participants will return to the clinic 28 days (+/- 1 day) after their last dose at 
Visit 3. Approximately 24mL of blood will be drawn, urine sample, and a finger stick will 
be collected, along with hair sample. This visit will also include urine and rectal STI 
screening. 
ARM B (n=20; arm will close to enrollment once 10 people have completed study 
visits) 
Visit 1 (screening): Eligible MSM will be questioned about their medical history, 
undergo an HIV test, and a peripheral blood sample for creatinine and hepatitis B 
testing, as well as testing for baseline levels of study drug. A physical exam may also be 
completed. Participants will then be asked to return within 1-6 weeks for visit 2.
Visit 2: Participants will return to the clinic to receive their first set of study drug for 
weekly 2-1-1 dosing. The first dose of 2 pills will be taken in clinic, the next dose of 1 pill 
to be taken 24 hours later at home, and the last dose at home 48 hours from the first 
dose (24 hours after the second dose). Participants will be instructed to take their 2-1-1 
dosing on the same days every week. Participants will be instructed to provide 
documentation of all other dosing with a time-stamped video or picture.
Visits 3-14: Participants will return after finishing their weekly 2-1-1 dose, to do their 
weekly convenience sampling. Approximately 24 mL of blood will be drawn, urine 
sample, and a finger stick will be collected. An HIV test will be completed at visits 6, 10 
and 14 (once per month) along with hair samples. Urine and rectal STI screenings will 
be conducted at visit 10.  An additional creatinine test will be done at visit 14. 
Participants will be provided with their medication at visits 5, 8, and 11.
Visit 15: Participants will return to the clinic to take their final dose of study drug in 
clinic. After the dose is taken, approximately 24mL of blood will be drawn, urine sample, 
and a finger stick will be collected. 
Visit 16: Participants will return to the clinic 24 (+/- 2 hrs) hours after their last dose at 
Visit 15. Approximately 24mL of blood will be drawn, urine sample, and a finger stick will

Contingency visit:
Attempts to ensure adherence to the study visits will be made with telephone and/or 
email reminders to the participant.  However, if for example, screening laboratory results 
are lost or are inconclusive or if a participant has been unable to adhere to study 
protocol, he may be rescheduled for a future date where the above visit procedures will 
be performed.  These additional visits will be scheduled within the above visit windows.  
Missed Visits:
In all arms, up to 3 missed visits (~15% of all study visits) are allowed. 
Timing of procedures after dose:
The procedures conducted after dose, particularly those less than 24 hours after dose, 
should occur as close to the scheduled time points as possible. Protocol deviations will 
be filed for visits that occur outside of the target windows identified above only if the visit 
is conducted more than 3 hours beyond the target window defined above for each arm 
and visit. 
Phone calls/retention contacts:
While on study, periodic phone calls, texts, or email reminders will occur between study 
staff and participants to ensure proper retention and adherence to study protocol.  
Statistical Analysis Plan
Primary study outcome: Median (range) TFV-DP concentrations in dried blood spots will
be measured at Visit 4 in Arm A and compared to TFV-DP concentrations in dried blood 
spots measured at Visit 16 in Arm B to compare accumulation of drug following weekly 
ED-PrEP dosing. In addition, TFV-DP concentrations in dried lood spots will be 
measured at Visit 16 in Arm C and compared to TFV-DP concentrations in dried blood 
spots measured at Visit 16 in Arm D to compare accumulation of drug following the 
different ED-PrEP dosing strategies. Differences in median drug concentrations 
between arms will be
analyzed with a non-parametric Wilcoxon-signed rank tests and a p-value <0.05 will be
considered significant.
Other drug level outcomes will be exploratory.
Future use of specimens
Leftover biologic specimens will be stored and use for future research use at Emory 
University Hope Clinic or the CDC. Stored samples will only be distributed to 
researchers who have obtained protocol approval from an IRB (or appropriate waiver).

RISKS AND HOW MINIMIZED
HIV risk counseling
Participants that are tested for HIV to ensure eligibility will undergo HIV risk reduction 
counseling (e.g. increasing condom use, reducing number of partners, addressing 
substance abuse, etc.) by the study PI or study staff with provision of condoms and 
lubricant available freely at the Hope Clinic. HIV rapid testing will then be conducted 
with a CLIA waived product with finger-stick or whole blood from phlebotomy, 
depending on the test. Any participant who is found to be HIV positive on rapid testing 
will be referred for confirmatory testing to their local health department, community 
based organization that provides HIV testing, or provider of their choice. We will also 
assist any HIV positive participant in accessing healthcare for HIV infection as needed. 
Participants will also be educated about HIV pre-exposure prophylaxis during the study 
by the coordinator and/or study clinician. After completion of the study, all participants 
who are interested in PrEP for HIV prevention will be linked to community services. A 
detailed listing of PrEP services available for insured and uninsured clients in Atlanta 
can be found at www.preplocator.org. Dr. Kelley is active in PrEP implementation in the 
Atlanta community and can facilitate these linkages.   
Blood sample collection
The most common risks of blood sample collection are pain at the puncture site, 
bruising, and a feeling of lightheadedness. To minimize these risks, blood draws will be 
performed by trained personnel, and will be performed in a secure environment with 
access to first aid equipment, bandages, and trained healthcare professionals. 
Risk of TDF/FTC
TDF/FTC is a combination anti-HIV medication that contains the drugs tenofovir and 
emtricitabine. Based on clinical trials previously conducted of TDF/FTC, the drug 
showed to be well tolerated (see package insert). The most common adverse events 
reported in clinical trials (> 5% incidence) included diarrhea, nausea, and headache. 
Additional adverse reactions occurring in less than 2% of subjects administered 
TDF/FTC included vomiting, flatulence, dyspepsia, abdominal pain, rash, and 
depression
 
Renal toxicity and bone density loss are rarely reported with chronic use of TDF 
containing products and are not expected to occur with the regimen prescribed in this 
protocol. Similarly, lactic acidosis and severe hepatomegaly have rarely been 
associated with medications in the same class as TDF and FTC.
Use of TDF/FTC can also cause flare-ups in those who have hepatitis B virus.  It can 
cause the Hepatitis B virus to suddenly return in a worse form than before if treatment

was provided (see package insert). For this reason, it is important that participants not 
participate in the study if they are known to have Hepatitis B.   
Acquisition of HIV drug resistance is a theoretic concern for HIV positive people taking 
intermittent dosing of anti-HIV medication. For this protocol, we will test participants for 
HIV at study entry and monitor clinically for high-risk behavior or any signs of acute HIV 
infection at study visits.  We will only enroll participants at lower risk for HIV and who 
report consistent condom use. If high-risk behavior (e.g. unprotected anal intercourse 
with a man of unknown HIV status) or symptoms of acute HIV infection are reported, 
and HIV antigen/antibody test will be repeated and the participant will be counseled 
about the need for any follow-up testing.  Clinical signs and symptoms of acute HIV 
infection that will be queried include: fever, fatigue, malaise, skin rash, swollen glands, 
oral/genital ulcers, myalgia/arthralgia(3).  Dr. Kelley will review all reports of clinical 
signs/symptoms to determine appropriate follow-up and linkage to care as necessary.  If 
a diagnosis of acute HIV infection is thought to be possible or determined by repeat HIV 
testing, the participant will be discontinued from the study. 
Participants taking TDF/FTC will be counseled that they should not expect to achieve 
protection from HIV infection by taking drug during this study, as they will be provided a 
limited supply. All participants included in the study that have an interest in taking PrEP 
for HIV prevention, will be referred to an area PrEP provider at the termination of the 
study. The Hope Clinic has compiled a resource sheet of area providers that will be 
distributed to interested participants.  All participants will be offered condoms and 
lubricants at every study visit. 
BREACH OF CONFIDENTIALITY
All measures will be taken to ensure information provided by participants is kept 
confidential.  Identifying paper information will be kept in a separate locked office and 
only accessible by the PI and study coordinator.  Electronic data will be stored on the 
Redcap server or the Emory School of Medicine HIPPAA compliant servers, which will 
be accessible to the PI and study staff only.  All study specimens will be labeled with a 
unique identifier prior to transport to CDC.  Identifying information will not be shared with 
laboratory collaborators at the CDC and they will be unable to link the study ID to any 
identifying information.  Any demographic data shared with CDC will also be stripped of 
HIPPAA identifiers prior to sharing.  
BENEFITS
Subjects will not derive direct benefit from this study. 
COST
There is no cost to subjects to participate in this study.

ALTERNATIVE
The alternative to participating in this study is to decide not to participate. Subjects can 
withdraw their consent at any time.
COMPENSATION
All participants will be compensated for their time and inconvenience of study 
participation. Compensation will be provided on a web-based, reloadable, debit card 
(ClinCard) that automates reimbursements. The ClinCard will be provided by study staff 
at the participants’ initial visit (visit 1), and funds will be loaded after the completion of 
each visit.
Arm A (closed as of 7/14/21)
Participants will receive $20 for the screening visit, $20 for each study visit involving 
sampling procedures, to compensate for time and effort. If participants do not finish the 
study, we will compensate for the visits they have completed ($180 total for those who 
finish all study visits). Participants who complete all 9 study visits for Arm A will receive 
a $50 “finishing bonus” at their last visit, to improve retention in this arm. 
Arms B, C & D
Participants will receive $50 for each visit they complete to compensate for time and 
effort. If participants do not finish the study, we will compensate for the visits they have 
completed ($1050 total for those who finish all study visits). Participants who complete 
at least 18 study visits for Arm B, C, and D (miss a maximum of 3 visits) will receive a 
$100 “finishing bonus” at their last visit, to improve retention in this arm. 
If a contingency visit is necessary, participants will be compensated $20 for completion 
of a contingency study visit.
There is no charge for parking at the Hope Clinic. However, participants may be 
provided with a MARTA card if available. 
PLAN FOR OBTAINING INFORMED CONSENT
After being screened for eligibility by the PI or study coordinator, subjects will be 
informed about the study and asked to sign an Emory IRB approved informed consent. 
The consent form will describe the purpose of the study, the procedures to be followed, 
and the risks and benefits of participation. Subjects may complete the informed consent 
process electronically or in person. If informed consent is performed in person, subjects 
will be consented in a private exam room.  Subjects will be given time to read the 
consent, ask questions and consider the risks and/or benefits to participation in this 
research study prior to obtaining their signature. All subjects enrolled in the study will be 
given a copy of their signed and dated informed consent document. This consenting 
process will be done by trained research staff at the Hope Clinic. If participants 
complete informed consent electronically, they will use an approved e-consent platform.

This will be sent to participants prior to their first visit via a secure and unique link. 
Participants will be given direct contact information for the study staff in order to answer 
any questions or concerns they may have and will electronically sign the consent form 
via the online platform. A copy of the consent form will be available to participants for 
download at the time of consent. All subjects will undergo HIV risk reduction counseling 
with provision of free condoms at their first in-person visit.
PROVISIONS FOR SUBJECTS FROM VULNERABLE POPULATIONS
Non-English speaking subjects or illiterate subjects will not be eligible to participate in 
this study.  
PARTICIPATION OF WOMEN AND CHILDREN
Because this is a study of MSM, those assigned female sex at birth are not eligible. It is 
especially important to include MSM aged 18-21 as young MSM are at highest risk of 
HIV infection and research that may lead to better prevention interventions, including an 
HIV vaccine, are desperately needed for this group. Children younger than 18 will not 
be eligible.   
SUBJECT PRIVACY AND DATA CONFIDENTIALITY
All subjects will provide informed consent in a private room at the Hope Clinic or on a 
secure electronic consenting platform.
Case report forms (CRFs) will be provided for each subject to collect demographic, 
behavioral, clinical, and laboratory data at study entry, and additional clinical data at the 
study visit. These data will be collected from the screening clinical assessment, the 
study entry physical examination and screening laboratory tests, and rectal biopsy 
visits. Subjects will be identified by the participant identification number (PID), which will 
be provided by the study investigator upon registration.  All laboratory specimens, 
evaluation forms, reports, and other records that leave the site will be identified by 
coded number only to maintain subject confidentiality. All study samples will be kept in a 
secure area in a limited-access laboratory facility and only the research team will have 
access to the samples. The samples and data will be identified only by code numbers.
Any identifiable records will be kept locked accessible only by authorized study 
personnel. Electronic data will be password protected and stored on the Redcap server 
or the Emory School of Medicine HIPAA compliant server. Biologic samples will be 
coded with a unique identifier and no identifiable behavioral data will be shared with 
laboratory investigators at CDC.  Information about the subject’s participation will not be 
shared with individuals who are not directly involved with the research subjects.  Clinical 
information will not be released without written permission of the subject, except as 
necessary for monitoring by IRB, the FDA, the NIH, or the OHRP. Information about the 
subject’s participation will not be shared with individuals who are not directly involved 
with the research subjects.

PLANS FOR SUBJECTS AT THE END OF THE PROTOCOL
Subjects will return to the standard of care at the end of the protocol.  Subjects who are 
interested in starting PrEP will be linked to care with a community provider. In the event 
that study staff needs additional information, after enrollment is complete, or has 
additional questions pertaining to study analysis, staff will obtain consent from 
participant for future contact. 
CLINICAL SITE MONITORING AND RECORD AVAILABILITY
The Emory University IRB, the OHRP, FDA, or other government regulatory authorities 
may perform clinical site monitoring.  Clinical research sites monitoring may include the 
review of the individual participant records, including consent forms, CRFs, supporting 
data, laboratory specimen records, and medical records (physicians’ progress notes, 
nurses’ notes, individuals’ hospital charts) to ensure protection of study participants, 
compliance with the protocol, and accuracy and completeness of records.  The monitors 
may also inspect sites’ regulatory files to ensure that regulatory requirements are being 
followed.
The investigators will make study documents (e.g., consent forms, CRFs) and pertinent 
hospital or clinic records readily available for inspection by the local IRB or the OHRP 
for confirmation of the study data.
ADVERSE EVENT MONITORING AND REPORTING 
Adverse Event Reporting 
An Adverse Event (AE) as any untoward medical occurrence in a clinical investigation 
subject administered a pharmaceutical product regardless of its causal relationship to 
the study treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), symptom or disease temporally associated 
with the use of a medicinal (investigational) product. 
Any AE that is reported to either the investigators or their designated research 
associates by a study subject or by medical staff caring for the subject and which meets 
the criteria will be documented in the participant’s chart.  The reporting period for 
participant AEs begins at enrollment and continues until the subject either completes or 
withdraws from the study. 
All AEs and laboratory abnormalities will be graded according to the Division of AIDS 
Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE 
Grading Table), Version 2.1, July 2017, which can be found on the DAIDS RCC Web 
site: http://rcc.tech-res.com/tox_tables.htm.    
Each AE will be assessed for relatedness to study product. Study investigators will 
determine AEs to be either definitely related, probably related, possibly related or not 
related to study product. If the adverse event is, in the investigator’s opinion, possibly,

probably, or not related to study drug or procedures, then an alternate etiology will be 
provided by the investigator. 
Related AEs ≥ Grade 3 will be included in the summary reports provided to the Medical 
Monitor of the study. Exceptions to expedited reporting are detailed below.  
This study uses FDA approved drugs with known common side effects (please refer to 
the risk section of the protocol for common side effects).  The following side effects will 
not be reported as an EAE unless it increases in severity or becomes prolonged.
Nausea: Report if severity is a Grade 3 or higher 
Vomiting: Report if severity is a grade 3 or higher 
Diarrhea: Report if severity is a Grade 3 or higher 
Headache: Report if severity is a Grade 3 or higher 
Rash: Report if severity is a Grade 3 or higher 
Serious Adverse Event Reporting 
Additionally, clinical investigators will monitor subjects for Serious Adverse Events 
(SAE) during each study visit.  
A SAE is an adverse drug experience that results in any of the following outcomes: 
1. Death. 
2. Life-threatening situation - The subject was at risk of death at the time of the 
adverse event/experience.  It does not refer to the hypothetical risk of death if the 
AE were more severe or were to progress. 
3. Inpatient hospitalization or prolongation of existing hospitalization. 
4. Persistent or significant disability/incapacity - Any AE having an outcome that is 
associated with a substantial disruption of the ability to carry out normal life 
functions, including the ability to work.  This is not intended to include transient 
interruption of daily activities. 
5. Congenital anomaly/birth defects - Any structural abnormality in subject’s 
offspring that occurs after intrauterine exposure to treatment. 
6. Important medical events/experiences that may not result in death, be life 
threatening, or require hospitalization may be considered a serious adverse 
event/experience when, based upon appropriate medical judgment, they may 
jeopardize the subject and may require medical or surgical intervention to 
prevent one of the outcomes listed above, i.e., death, a life-threatening adverse 
event/experience, inpatient hospitalization or prolongation of existing 
hospitalization, a persistent or significant disability/incapacity, or a congenital 
anomaly/birth defect. Examples of such medical events/experiences include 
allergic bronchospasm requiring intensive treatment in an emergency room or at 
home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization, or the development of drug dependency or drug abuse.

In this protocol, spontaneous and elective abortions will be also be considered SAEs.  
All SAEs will be reported to the Medical Monitor within 24 hours of site awareness.  
Any SAE that is considered 1) unanticipated 2) related to study product AND 3) places 
participants at greater risk of harm than previous known is an Unanticipated Problem 
(UP) and will be reported to the IRB within 10 business days of study team awareness. 
All other SAEs will be reported to the IRB at the time of annual review. The standard 
Emory IRB reporting guidelines for AE and SAE reporting, as documented at 
http://www.emory.edu/IRB/guidelines_adverse_event.php, will be followed.   
It should however be noted that a severe adverse event /experience is not necessarily 
serious, as the term severe is a measure of intensity while a serious adverse event 
(SAE) is determined based on the aforementioned regulatory criteria. 
DATA SAFETY MONITORING 
Summaries of adverse events (Grades 3 or 4), and targeted AEs across study groups 
as well as study conduct will be reviewed regularly (in real time and summarized 
quarterly) by study investigators.  
We will also conduct site monitoring for data quality and protocol compliance. The PI 
and the research coordinators will monitor for protocol compliance and data quality with 
periodic quality monitoring checks. In addition, we will perform self-monitoring twice 
yearly using the EU-Self-monitoring Tool available at 
http://www.ctac.emory.edu/clinical_trial_resources/Audit%20Tools.html. The PI will 
inform the sub-investigators and the IRB if she is provided with new safety information 
about the study.  
STUDY DISCONTINUATION 
A study participant may elect to discontinue participation in the study at any time.  The 
study may be discontinued at any time by the IRB, the OHRP, or other government 
agencies as part of their duties to ensure that research subjects are protected. 
BIOHAZARD CONTAINMENT
Blood-borne pathogens can occur through contact with contaminated needles, blood, 
and blood products. Appropriate blood and secretion precautions will be employed by all 
personnel in the drawing of blood and handling of all specimens for this study, as 
currently recommended by the Centers for Disease Control and Prevention and the 
National Institutes of Health. All infectious specimens will be transported using 
packaging mandated in the Code of Federal Regulations, 42 CFR Part 72.

You Are Being Asked to Be in a Research Study
ARM B
You are being asked to be in a research study. A research study is designed to answer a scientific question. If 
you agree to be in the study you will be one of 40 people who are being studied, at Emory University Hope 
Clinic. 
Why is this study being done? 
This study is being done to answer the question: How useful are biomarkers to confirm self-reported 
adherence to event-driven PrEP. You are being asked to be in this research study because you identify as a 
man who has sex with men and you are between the ages of 18 and 59 years old.   
Do you have to be in the study? 
It is your decision to be part of this research study. You do not have to be in it. Your choice will not affect your 
access to medical care. Before you make your decision, you should take time to learn about the study.
What do I have to do if I choose to participate in this study?
If you are eligible and want to be part of the study, you will participate for no more than 24 weeks (21 study 
visits).  The researchers will ask to collect the following samples from you: blood, hair, urine, and a finger stick. 
What are the risks or discomforts I should know about before making a decision?  
The drug provided in this study will not protect participants from HIV or treat any active HIV infections. All 
studies have some risks.  Some risks are relatively small, like being bored or losing time.  Some are more 
serious – for this study, the drugs that are tested have been shown to be well tolerated, but can include 
common side effects such as, diarrhea, nausea, and headaches. Tenofovir and emitricitabine (TDF/FTC) can 
also cause flare-ups in those who have hepatitis B virus. The risks of loss of privacy and breach of 
confidentiality are rare but can occur.  A full list of expected risks, their frequency and severity are in the “What 
are the possible risks and discomforts?” section of this document.
Alternatives to Joining This Study
Since this is not a treatment study, the alternative is not to participate or to consider participating in another 
study.
Costs
You WILL NOT have to pay for any of the study procedures while participating in this study.  
There is more information in the cost section below.
What Should I Do Next?
Read this form, or have it read to you.  Make sure the study doctor or study staff explains the study to you. Ask 
questions (e.g., about exact time commitment, about unfamiliar words, more details on specific procedures, 
etc.).Take time to consider this and talk about it with your family and friends.

Title: Biomarkers for Event-Driven PrEP Adherence
Principal Investigator: Colleen F. Kelley MD, MPH
Study-Supporter: Center for Disease Control and Prevention (CDC)
Introduction
You are being asked to be in a medical research study. This form is designed to tell you everything you need 
to think about before you decide if you want to be a part of the study.  It is entirely your choice.  If you 
decide to take part, you can change your mind later on and withdraw from the research study. The 
decision to join or not join the research study will not cause you to lose any medical benefits.  If you decide not 
to take part in this study, your doctor will continue to treat you.
Before making your decision:
•
Please carefully read this form or have it read to you
•
Please listen to the study doctor or study staff explain the study to you 
•
Please ask questions about anything that is not clear
You can take a copy of this consent form, to keep. Feel free to take your time thinking about whether you 
would like to participate. You may wish to discuss your decision with family or friends. Do not sign this consent 
form unless you have had a chance to ask questions and get answers that make sense to you.  By signing this 
form, you will not give up any legal rights.
A description of this clinical trial will be available on http://www.ClinicalTrials.gov, as required by U.S. law. This 
Web site will not include information that can identify you. At most, the Web site will include a summary of the 
results. You can search this Web site at any time.
What is the purpose of this study?
The purpose of this study is to understand how useful biomarkers are to confirm self-reported adherence to 
event-driven PrEP in men who have sex with men. The study drug being examined in this study is Truvada. 
The study drug provided is not intended to protect you from HIV or treat any active infection. 
This study will consist of 40 healthy, HIV-negative men, aged 18-59, who have sex with men. There are a total 
of 4 arms in this study (A, B, C, & D.) You are being asked to participate in Arm B. There will be a total of 20 
men in this study arm. Study participants will take 2-1-1 dosing of the study drug. This means you will take 2 
pills first, then 1 pill 24 hours later, then another pill 48 hours later. The researchers will then take biological 
samples from participants and measure the amount of drug in the samples. Biological samples that will be 
taken include blood, hair, urine, and a finger stick.
What will I be asked to do?
If you decide to take part in this study, you will be asked to come to the Hope Clinic to complete 21 visits over a 
period of 24 weeks. 
Visit 1 (Screening):  If you agree to be in the study, this visit will likely take place on the same day you sign 
the consent form. The purpose of this visit is to see if you are a good fit for the study.  During this visit, you will 
be asked questions about your medical and sexual history and have an HIV blood test done.  You may also 
undergo a physical exam. Before and after HIV testing, we will counsel you about the test and results.  We will 
draw approximately 24 mL of blood (about 3 teaspoons) from your arm for other blood tests to see if you have

hepatitis B and to see whether your kidney function is normal.  If you are eligible to take part in the study, we 
will schedule you for your second study visit 1-6 weeks after your first visit.
Visit 2 (Enrollment): At this visit we will give you your first dose of the study drug (2 pills.) You will take the 
first dose of 2 pills while you are still in the clinic. At this visit you will also be given the next dose to be taken 24 
hours later, as well as the dose to take 48 hours later. In addition to that, you will be given your weekly 2-1-1 
doses for the next 2 weeks to be taken at home. Since you will take these doses on your own, we will ask you 
to take a time stamped photograph or videotape of yourself taking the pill.  You will also have the option to 
send a text to a specified number with the time and date of dose if your phone device does not have 
video/photo capabilities. These doses will need to be taken weekly, on the same days every week. 
Types of Samples 
Standard Biological Samples
There are a set of biological samples that will be collected from all participants at each post-dose visit (Visits 3-
21). We will refer to them as “standard samples” for the rest of this document. The standard samples include:
•
Blood: We will draw approximately 24 mL (about 5 teaspoons) of blood from your arm.
•
Urine sample: Some of which will be used for gonorrhea and chlamydia testing.
Hair Sample
At visits 6, 10, 14 and 21 (monthly) we will also ask for:
•
Hair sample: we will cut a small sample (about 50-100 strands) with scissors. 
The timing of the visits is very important in this study so it is important that you keep all scheduled 
appointments.

How will my medicine be provided? 
The medicine that you will take will be dispensed by the pharmacy and delivered to the principal investigator or 
study team member.  The principal investigator or health care providers on his/her research team will provide 
the medicine to you.  If you have questions about the medicine, you should ask the principal investigator or 
study nurse.  You may also call the pharmacy at 
 if you have questions about the medicine. The 
number for the pharmacy is included on your medicine package.
Who owns my study information and samples?
If you join this study, you will be donating your samples and study information.  You will not receive any 
compensation if your samples or information are used to make a new product. If you withdraw from the study, 
data and samples that were already collected may still be used for this study. If you decide to withdraw from 
the study and would like us to destroy any remaining sample, please contact Dr. Kelley in writing at:

What are the possible risks and discomforts?
There may be side effects from the study drug or procedures that are not known at this time. Everyone taking 
part in the study will be watched carefully for any side effects. Most side effects go away soon after stopping 
Truvada. You should talk to the study doctor about any side effects that you experience while taking part in this 
study. 
Possible risks and discomforts related to the study procedures include the following:
STI Testing
It is possible that you will find out that you have HIV, gonorrhea or chlamydia during this study. This could 
cause you some stress. Study staff will be available for counseling before and after your test, regardless of the 
results. Also, we will refer you to a medical provider for further care. 
Blood Draw
Having your blood taken can cause discomfort. This discomfort is temporary but may cause lightheadedness 
or fainting. Taking blood can cause bruising. Bruising can be prevented or reduced by putting pressure on the 
site for a few minutes after the blood is taken. Rarely, some people get an infection where the needle was put 
in their arm to draw the blood. To reduce the risk of infection, we will wipe the area clean with alcohol and use 
sterile equipment.
Truvada (TDF/FTC)
Truvada (TDF/FTC) is a combination anti-HIV medication that contains the drugs tenofovir and emtricitabine. 
Based on clinical trials previously conducted of TDF/FTC, the drug showed to be well tolerated (see package 
insert). The most common adverse events reported in clinical trials (> 5% incidence) included diarrhea, 
nausea, and headache. Additional adverse reactions occurring in less than 2% of subjects administered 
TDF/FTC included vomiting, flatulence, dyspepsia, abdominal pain, rash, and depression.
Renal toxicity and bone density loss are rarely reported with chronic use of TDF containing products and are 
not expected to occur with the regimen prescribed in this protocol. Similarly, lactic acidosis and severe 
hepatomegaly have rarely been associated with medications in the same class as TDF and FTC.

Version Date: 08/16/2021
IRB Form 12142018   
Use of TDF/FTC can also cause flare-ups in those who have hepatitis B virus.  It can cause the Hepatitis B 
virus to suddenly return in a worse form than before if treatment was provided (see package insert). For this 
reason, it is important that participants not participate in the study if they are known to have Hepatitis B.   
If you will be taking the study drug home, keep it out of the reach of children or anyone else who may not be 
able to read or understand the label.  Do not let anyone else take the study drug besides you.
The medication provided in this study is not for treatment or prevention of HIV infection, and you should not 
expect that you will be protected from HIV by taking the medications in this study. If you are interested in pre-
exposure prophylaxis (PrEP) after this study ends, we can refer you to a medical provider who can prescribe 
PrEP. 
New Information
It is possible that the researchers will learn something new during the study about the risks of being in it.  If this 
happens, they will tell you about it. Then you can decide if you want to continue to be in this study or not.  You 
may be asked to sign a new consent form that includes the new information if you decide to stay in the study.
Will I benefit directly from the study? 
This study is not designed to benefit you directly. This study is designed to evaluate the usefulness of 
biomarkers to confirm self-reported adherence to event-driven PrEP. The study results may be used to help 
others in the future if this regimen is one day an approved pre- exposure prophylaxis (PrEP) regimen. 
Will I be compensated for my time and effort?
Compensation will be provided on a web based, reloadable, debit card (ClinCard) that automates 
reimbursements. The ClinCard will be provided by study staff at the initial visit (visit 1). 
All payments are made using a personal payment card. We issue this to you for free. The payment card is a 
prepaid debit card. It can be used exactly like a MasterCard. We load money onto your card electronically 
every time you need to be paid. The card scheme is run by Greenphire, an independent company specializing 
in payments for research studies and clinical trials. To issue your card, we need to give Greenphire some of 
your personal information. Banks and other financial institutions can access this information if they need to 
verify your identity when you use your card. 
Emory University is required by law to report any payments we make to the IRS. To do this, Emory University 
Department of Finance needs to keep your Social Security Number on file. We are asking you to allow us to 
communicate your name, address, date of birth, research study name and Social Security Number to 
Greenphire and Emory University Department of Finance. If you want to receive e-mail or text alerts when 
payments are made to you, we will ask you to provide your e-mail or phone number as well. All of this 
information will be stored on computers owned by Greenphire.  Greenphire will not have access to any other 
information collected during this study. Full instructions about using your card are included when we issue it. 
Please ask if you have any questions or concerns about the card scheme.
We would also like the option of compensating you in the form of cash, check or gift card if ClinCard 
accessibility is not available. You may be asked to fill out a tax form, including your Social Security or Taxpayer 
Identification Number, in order to be reimbursed, depending on the amount and method of payment. Some 
payment methods involve mail coming to your house, which may be seen by others in your household. You 
can decline payment if you are concerned about confidentiality, or you can talk to the study team to see if there 
are other payment options. 
You will get $50 for each visit to compensate you for your time and effort.  If you do not finish the study, we will 
compensate you for the visits you have completed. You will get $1050 total, if you complete all study visits. We

permit missing up to three visits (completing 18 visits.) If you complete 18 visits for the study, you will receive a 
$100 bonus for completion of the study, for a total of $1150. If an extra study visit is necessary, you will receive 
$20 for completion of that study visit.
If you have trouble with transportation to study visits, please let the study staff know. We may be able to help 
(e.g. MARTA ride card).
What are my other options?
If you decide not to enter this study, there is care available to you outside of this research study. The study 
doctor will discuss these with you. 
Taking part in this study, however, may make you unable to participate in some other research studies, if they 
exclude people who have taken certain treatments.  You should discuss this with the researchers if you have 
concerns. You may wish to research other study options at websites like clinicaltrials.gov and 
ResearchMatch.org.
How will you protect my private information that you collect in this study?
Whenever possible, a study number, rather than your name, will be used on study records.  Your name and 
other identifying information will not appear when we present or publish the study results.
Certain offices and people other than the researchers may look at study records. Government agencies and 
Emory employees overseeing proper study conduct may look at your study records.  These offices include the 
Food and Drug Administration (FDA), the Office for Human Research Protections, the sponsor, the Emory 
Institutional Review Board, the Emory Office of Research Compliance. Study funders may also look at your 
study records. Emory will keep any research records we create private to the extent we are required to do so 
by law.  A study number rather than your name will be used on study records wherever possible. Your name 
and other facts that might point to you will not appear when we present this study or publish its results. 
Certificate of Confidentiality
There is a Certificate of Confidentiality from the National Institutes of Health for this Study.  The Certificate of 
Confidentiality helps us to keep others from learning that you participated in this study.  Emory will rely on the 
Certificate of Confidentiality to refuse to give out study information that identifies you.  For example, if Emory 
received a subpoena for study records, it would not give out information that identifies you.
The Certificate of Confidentiality does not stop you or someone else, like a member of your family, from giving 
out information about your participation in this study.  For example, if you let your insurance company know 
that you are in this study, and you agree to give the insurance company research information, then the 
investigator cannot use the Certificate to withhold this information. This means you and your family also need 
to protect your own privacy.
The Certificate does not stop Emory from making the following disclosures about you:
•
Giving state public health officials information about certain infectious diseases,
•
Giving law officials information about abuse of a child, elderly person or disabled person.
•
Giving out information to prevent harm to you or others.
Giving the study sponsor or funders information about the study, including information for an audit or 
evaluation.
Storing and Sharing your Information
Samples collected during the study will be sent to the Centers for Disease Control (CDC) for testing.

De-identified data from this study (data that has been stripped of all information that can identify you), including 
your de-identified genetic information, may be placed into public databases where, in addition to having no 
direct identifiers, researchers will need to sign data use agreements before accessing the data. We will remove 
or code any personal information that could identify you before your information is shared. This will ensure that, 
by current scientific standards and known methods, it is extremely unlikely that anyone would be able to 
identify you from the information we share. Despite these measures, we cannot guarantee anonymity of your 
personal data.
Your data and specimens from this study may be useful for other research being done by investigators at 
Emory or elsewhere. To help further science, we may provide your de-identified data and/or specimens to 
other researchers. If we do, we will not include any information that could identify you. If your data or 
specimens are labeled with your study ID, we will not allow the other investigators to link that ID to your 
identifiable information.
We will use your sample and data only for research. We will not sell them. However, the results of this 
research might someday lead to the development of products (such as a commercial cell line, a medical or 
genetic test, a drug, or other commercial product) that could be sold by a company. You will not receive money 
from the sale of any such product.
In general, we will not give you any individual results from the study of the samples you give us. If we find 
something of urgent medical importance to you, we will inform you, although we expect that this will be a very 
rare occurrence.
Future use of specimens
Leftover specimens may be stored for future research use at the CDC or at the Hope Clinic. You cannot 
participate in this protocol if you do not want your specimens stored for possible future use. At this time, there 
are no plans for genetic testing of the specimens.  However, it is possible that researchers may choose to do 
genetic testing in the future on the stored specimens.  Your name and personal identifying information will not 
be labeled on the stored specimens.
How is my Genetic Information Protected? What are the Risks?
The Genetic Information Nondiscrimination Act (GINA) is a federal law that generally makes it illegal for health 
insurance companies, group health plans, and most employers to discriminate against you based on your 
genetic information. This law generally will protect you in the following ways: 
•
Health insurance companies and group health plans may not request your genetic information that we 
get from this research.
•
Health insurance companies and group health plans may not use your genetic information when 
making decisions regarding your eligibility or premiums. 
•
Employers with 15 or more employees may not use your genetic information that we get from this 
research when making a decision to hire, promote, or fire you or when setting the terms of your 
employment.
Be aware that GINA does not protect you against genetic discrimination by companies that sell life insurance, 
disability insurance, or long-term care insurance, and does not apply to employers with less than 15 
employees.
In addition to GINA, the State of Georgia has laws that prohibit insurers from using genetic testing information 
for any non-treatment purpose.  However, like GINA, this state law protection has exclusions: life insurance 
policies, disability income policies, accidental death or dismemberment policies, Medicare supplement policies, 
long-term care insurance policies, credit insurance policies, specified disease policies, hospital indemnity

policies, blanket accident and sickness policies, franchise policies issued on an insurance policy written as a 
part of workers’ compensation equivalent coverage, or other similar limited accident and sickness policies.
Privilege 
In the State of Georgia, in some circumstances your genetic information may have special legal protections 
called “privilege.” This means that the information cannot be used as evidence in a court. By allowing us to use 
and disclose your genetic information for this research study along with other information about you that 
genetic information used in the research may no longer have that legal protection. Other protections described 
in this form will still apply. There are also other confidentiality protections for research data in general under 
Georgia state law.  
Storage and release of samples, genomic data, and health information
Portions of your samples, genomic data, and health information will be stored and shared with other 
researchers. The samples and information will be available for any research question, such as research to 
understand what causes certain diseases (for example heart disease, cancer, or psychiatric disorders), 
development of new scientific methods, or the study of where different groups of people may have come from.
Unrestricted access databases
If researchers choose to do genetic testing in the future on stored specimens, the information from this study 
will be freely available in a public, unrestricted database that anyone can use.  The public database will include 
information on hundreds of thousands of genetic variations in your DNA code, as well as your ethnic group and 
sex. The only health information included will be whether you had a particular disease or not. This public 
information will not be labeled with your name or other information that could be used to easily identify you. 
However, it is possible that the information from your genome, when combined with information from other 
public sources could be used to identify you, though we believe it is unlikely that this will happen.
Medical Record
If you have been an Emory Healthcare patient before, then you already have an Emory Healthcare medical 
record.  If you have never been an Emory Healthcare patient, you do not have one. An Emory Healthcare 
medical record will be made for you if an Emory provider or facility gives you any services or procedures for 
this study.  
We will take reasonable steps to keep copies of this form out of Emory Healthcare’s medical records system.  
If we aren’t successful in keeping these forms out, despite our efforts, we will take steps to remove them. If 
they cannot be removed, we will take steps to limit access to them. 
Emory Healthcare may create study information about you that can help with your care.  For example, the 
results of study tests or procedures.  These study results will be put in your Emory Healthcare medical record. 
Anyone who has access to your medical records will be able to have access to all the study information placed 
there.  The confidentiality of the study information in your medical record will be protected by laws like the 
HIPAA privacy rule.  State and federal laws may not protect the research information from disclosure.  We will 
ask for your authorization if we need to obtain any information from your medical record. 
We will also keep a separate research record of all study tests and procedures that we will use for research 
purposes.  This research record will not be a part of your medical record. For this study, those items include:
•
Medical History & Physical Examination
•
Laboratory testing
•
HIV testing & Pretest Counseling
Tests and procedures done at non-Emory places may not become part of your Emory medical record. Also, if 
you decide to be in this study, it is up to you to let your other health providers know.

Return of research results
Except for your HIV and STI test results, we will not give you any individual results from the study of the 
samples you give us. If we find something of urgent medical importance to you, we will inform you, although we 
expect that this will be a very rare occurrence.
In Case of Injury
If you believe you have become ill or injured from this research, you should contact Dr. Colleen Kelley at 
telephone number 
. You should also let any health care provider who treats you know that you 
are in a research study.  
If you get ill or injured from being in the study, Emory will help you to get medical treatment. Neither Emory nor 
the sponsor will pay for your medical treatment.  Your insurer will be billed for your treatment costs.  If you do 
not have insurance, or if your insurance does not pay, then you will have to pay these costs.   
Emory and the sponsor have not, however, set aside any money to pay you if you are injured as a result of 
being in this study or to pay for this medical treatment. For Emory, the only exception is if it is proven that your 
injury or illness is directly caused by the negligence of an Emory employee. “Negligence” is the failure to follow 
a standard duty of care. You do not give up any legal rights you may have by being in this study, including any 
right to bring a claim for negligence.  
Costs
There will be no costs to you for participating in this study, other than basic expenses like transportation. You 
will not be charged for any of the research activities. If the study procedures result in any medical 
complications that would not fall under “injury” as discussed above, the cost of treatment for those 
complications may be charged to you or your insurance.  
Withdrawal from the Study
You have the right to leave a study at any time without penalty.  
For your safety, however, you should consider the study doctor’s advice about how to go off the study 
treatment.  If you leave the study before the final planned study visit, the researchers may still use your 
samples unless you revoke your authorization.
The researchers also have the right to stop your participation in this study without your consent for any reason, 
especially if they believe it is in your best interest or if you were to object to any future changes that may be made 
in the study plan.  
These are the expected reasons why the researchers may stop your participation:
•
If you are unable or unwilling to follow all of the study procedures or instructions,
•
You could be harmed by study drug and/or study procedures,
•
You are not able to attend clinic visits or complete all of the study procedures, or
•
Other reasons, as decided by the study staff.
