HPTN 084 Safety

The safety profile of APRETUDE was established in >1600 cisgender women at risk of acquiring HIV-1 in HPTN 084. The information below gives an overview of the adverse reactions of APRETUDE as observed in HPTN 084, including treatment-related adverse reactions, discontinuation rates due to adverse reactions, and injection-site reactions (ISRs).

Adverse Reactions

HPTN 084: Safety profile established in >1600 participants1

The most common adverse reactions regardless of severity reported in ≥1% of participants in HPTN 084 are presented below.

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

Pooled analysis of incidence of injection site reactions from  Week 4 to Week 48
Adverse Reactions Table

*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 084, APRETUDE (n = 1519) and TDF/FTC (n = 1516). Fatigue includes fatigue, malaise. §Abdominal pain includes abdominal pain, upper abdominal pain. Rash includes rash, erythema, pruritus, macular, papular, maculopapular. Sleep disorders include insomnia, abnormal dreams.

1% of participants receiving APRETUDE and 1% of participants receiving TDF/FTC discontinued due to adverse reactions (all causality).


  • 38% of participants in the APRETUDE arm experienced at least 1 ISR, most of which were characterized as mild to moderate
    • The majority (>99%) were Grade 1 or 2, with <1% 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 084 included pain/tenderness (90%), swelling (18%), nodules (14%), and induration (12%)
    • The median duration was 8 days
  • No participants receiving APRETUDE discontinued due to ISRs
  • The proportion of ISRs reported 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

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