HPTN 083 Safety

The safety profile of APRETUDE was established in >2200 cisgender men and transgender women who have sex with men and have evidence of high-risk behavior for HIV-1 infection in HPTN 083. The information below gives an overview of the adverse reactions of APRETUDE as observed in HPTN 083, including treatment-related adverse reactions, discontinuation rates due to adverse reactions, and injection-site reactions (ISRs).


HPTN=HIV Prevention Trials Network.

Adverse Reactions

HPTN 083: Safety profile established in >2200 participants1

The most common adverse reactions regardless of severity reported in ≥1% of participants in HPTN 083 are presented below.

Adverse Drug Reactions* of All Grades Reported in at Least 1% of Participants Receiving APRETUDE

Adverse reactions 83
Adverse reactions 83

*Adverse reactions defined as “treatment-related” as assessed by the investigator, with exception of injection-site reactions, where all injection-site reactions were reported regardless of causality. Participants who received injection: HPTN 083, APRETUDE (n = 2117) and TDF/FTC (n = 2081). Pyrexia includes pyrexia, feeling hot, chills, influenza-like illness. §Fatigue includes fatigue, malaise. ||Sleep disorders include insomnia, abnormal dreams. Abdominal pain includes abdominal pain, upper abdominal pain.


FTC=emtricitabine; TDF=tenofovir disoproxil fumarate.

Discontinuation of therapy due to adverse reactions (all causality) was seen in 6% of participants receiving APRETUDE and 4% of participants receiving TDF/FTC.


  • 82% of participants in the APRETUDE arm experienced at least 1 ISR, most of which were characterized as mild to moderate
    • The majority (97%) were Grade 1 or 2, with 3% of participants experiencing Grade 3 and no Grade 4 reactions reported
    • The most common ISRs (all grades) reported in at least 10% of participants who experienced at least 1 ISR (all causality) with APRETUDE in HPTN 083 included pain/tenderness (98%), nodules (15%), induration (15%), and swelling (12%)
    • The median duration was 4 days
  • The proportion of participants reporting ISRs at each visit and the severity decreased over time
    • Self-reported ISRs could potentially underestimate the true rate of ISRs over time. ISRs may still be present but not reported during the course of the study
  • 3% of participants who experienced an ISR discontinued APRETUDE as a result of these reactions

Grade 1=mild; Grade 2=moderate; Grade 3=severe.
