NCT02919306

Brief Summary

The purpose of the study is to assess: 1 safety and tolerability of adenovirus serotype 26 (Ad26) prime and Modified Vaccinia Ankara (MVA) boost versus placebo in participants on suppressive antiretroviral therapy (ART) that was initiated during acute Human Immunodeficiency Virus (HIV) infection; 2) Measure the frequency and duration of sustained viremic control after receiving Ad26 prime/MVA boost or placebo, defined as greater than 24 weeks with plasma HIV ribonucleic acid (RNA) lesser than (\<)50 copies/ml after antiretroviral (ARV) analytical treatment interruption (ATI).

Outcome Measures

Primary Outcomes (14)

  • Percentage of Participants With Grade 3 or 4 Solicited Local Adverse Events (AEs)

    Solicited local AE of grade 3 or 4 and that is thought to be related to study vaccine were reported. An AE is any untoward medical occurrence in a clinical study participant administered a investigational or non-investigational medicinal product. An AE does not necessarily have a causal relationship with the treatment. Solicited local AEs (at injection site) included pain/tenderness, erythema, induration, swelling, itching and warmth were collected and reported for 7 days after each vaccination.

    Up to Week 49 (7 days post each vaccination)

  • Percentage of Participants With Grade 3 or 4 Solicited Systemic AEs

    Solicited systemic AE of grade 3 or 4 and that is thought to be related to study vaccine were reported. Solicited systemic AEs included fever (defined as body temperature of 38.0-degree celsius or higher), fatigue, headache, myalgia, arthralgia, chills, nausea, vomiting, rashes, and general itching.

    Up to Week 49 (7 days post each vaccination)

  • Percentage of Participants With Grade 3 or 4 Unsolicited AEs

    Unsolicited AE with worst severity grade 3 or 4 and that is thought to be related to study vaccine were reported. Unsolicited AEs were defined as events that participants experienced but were not specifically asked about.

    Up to Week 52 (28 days after each vaccination)

  • Percentage of Participants With Solicited Local AEs for 7 Days After Each Vaccination

    An AE is any untoward medical occurrence in a clinical study participant administered a investigational or non-investigational medicinal product. An AE does not necessarily have a causal relationship with the treatment. Solicited local AEs (at injection site) included pain/tenderness, erythema, induration, swelling, itching and warmth were collected and reported for 7 days after each vaccination.

    Up to Week 49 (7 days post each vaccination)

  • Percentage of Participants With Solicited Systemic AEs for 7 Days After Each Vaccination

    Solicited systemic AEs included fever (defined as body temperature of 38.0-degree celsius or higher), fatigue, headache, myalgia, arthralgia, chills, nausea, vomiting, rashes, and general itching were collected and reported for 7 days after each vaccination.

Limitations and Caveats

Subgroup analyses were performed by Ad26 baseline seropositivity for the humoral (ie, binding antibody responses; Env ELISA IgG-t gp140) and cellular immune responses (ie, IFN T cell responses and epitope mapping), and by time to rebound (3 tertile subgroups) for both the humoral and cellular immune responses (all parameters). Due to the low number of participants in each subgroup, no firm conclusions could be made.
