Study summary

The purpose of this study is to evaluate the safety, tolerability and immunogenicity of Sendai HIV vaccine SeV-G(NP) given intranasally and Ad35-GRIN administered intramuscularly in prime-boost regimens in HIV-uninfected, healthy adult volunteers.

Read the detailed description

The study is a randomized, double-blind, placebo-controlled, dose-escalation trial assessing the safety, tolerability, and immunogenicity of SeV-G(NP) given intranasally by drops and Ad35-GRIN administered intramuscularly in each of four prime-boost regimens.

Volunteers will be screened up to 42 days before the 1st vaccination and will be followed for 12 months after the last vaccine administration (16 months after the first vaccination). It is anticipated that it will take approximately 6 months to enroll the study. Approximately 64 volunteers (48 vaccine and 16 placebo recipients) will be included in the study.

What researchers measure

Primary outcomes

  1. Number of participants with adverse events as a measure of safety and tolerability

    To evaluate the safety and tolerability of SeV-G(NP) and Ad35-GRIN administered in four prime-boost regimens.

    Time frame: 16 months approximately

Secondary outcomes

  1. Shedding

    To assess the presence and persistence of the SeV-G(NP) vector and the in vivo genetic integrity of the insert

    Time frame: 16 months

  2. Immunogenicity

    To assess (qualitative and quantitative) immune responses elicited by the different prime-boost regimens.

    Time frame: 16 months
