An Open Label Demonstration Project and Phase II Safety Study of Pre-Exposure Prophylaxis Use Among 15 to 17 Year Old Young Men Who Have Sex With Men (YMSM)

The aims of the study are to obtain additional data on the safety of FTC/TDF (Truvada®) and
to evaluate acceptability, patterns of use, rates of adherence, and measured levels of drug
exposure when YMSM are provided with open label FTC/TDF (Truvada®) and information regarding
safety and efficacy of FTC/TDF (Truvada®) as PrEP based on prior studies in adults. The study
will also examine patterns of sexual risk behavior among HIV-uninfected YMSM in the U.S. at
high risk of acquiring HIV infection who are provided with open label FTC/TDF (Truvada®) as
PrEP. The study will also explore the feasibility and acceptability of implementing an
efficacious risk reduction behavioral intervention prior to the provision of PrEP- PCC. The
inclusion of a behavioral intervention in this project not only addresses the ethical
responsibility of providing at least the minimum risk reduction education to all subjects
given the high HIV risk of the study population, but also builds behavioral skills to assist
subjects in reducing their risk when not taking PrEP. Furthermore, the study will evaluate
the process of protocol implementation to better understand how to best implement PrEP
research and program practice at adolescent medicine sites, including an evaluation of
consent procedures and the acceptability/feasibility of allowing youth minors to consent for
their own participation in HIV prevention intervention, to the extent allowable by local laws
and regulations, and to allow youth minor participation in a clinical trial without requiring
disclosure of their sexual orientation and risk behaviors to their parents or legal
guardians.

of the following:

- At least one episode of unprotected anal intercourse with an HIV-infected male
partner or a male partner of unknown HIV status during the last 6 months;

- Anal intercourse with 3 or more male sex partners during the last 6 months;

- Exchange of money, gifts, shelter, or drugs for anal sex with a male partner
during the last 6 months;

- Sex with a male partner and has had a sexually transmitted infection (STI) during
the last 6 months or at screening;

- Sexual partner of an HIV-infected man with whom condoms were not consistently
used in the last 6 months; or

during the last 6 months;

- Tests HIV antibody negative at time of screening;

- Willing to provide locator information to study staff;

- Willing to take PrEP;

- Willing to participate in behavioral intervention;

- Reports intention not to relocate out of AMTU study area during the course of the
study; and

- Does not have a job or other obligations that would require long absences from AMTU

Exclusion Criteria:

- Appears visibly distraught or presence of active serious psychiatric symptoms (e.g.,
active hallucinations, suicidal, homicidal, or exhibiting violent behavior) at the
time of consent;

- Intoxicated or under the influence of alcohol or other drugs at the time of consent;

- Any significant uncontrolled, active or chronic disease process that, in the judgment
of the site investigator, would make participation in the study inappropriate.
(Appropriately managed conditions, like well-controlled diabetes, would not preclude
enrollment; the site is encouraged to contact the Adolescent Medicine Trials Network
for HIV/AIDS Interventions (ATN) 113 Protocol Team if they are having difficulty
making the judgment.);

- Acute or chronic hepatitis B infection as indicated by positive hepatitis B surface
antigen (sAg) test at time of screening;

on bedside Schwartz formula: Glomerular filtration rate (GFR) = (0.413 x (height in
centimeters)) / (serum creatinine in mg/dl)), or serum creatinine > upper limit of
normal (ULN), or history of renal parenchymal disease or presence of only one kidney
at time of screening;

- Confirmed ≥ Grade 2 hypophosphatemia at time of screening;

- Confirmed ≥ Grade 2 hematologic system abnormality (White Blood Count (WBC), Absolute
Neutrophil Count (ANC), hemoglobin, or platelets) at time of screening;

- Confirmed ≥ Grade 2 hepatobiliary system abnormality (Aspartate aminotransferase
(AST), Alanine aminotransferase (ALT), or bilirubin) at time of screening;

- Confirmed proteinuria as indicated by urine dipstick result ≥ 1+ at time of screening,
regardless of urine protein to creatinine ratio (UP/C);

- UP/C > 0.37 g/g at time of screening, regardless of urine dipstick protein result;
