A Phase-1 Open-label Clinical Trial to Evaluate the Safety and Immunogenicity of Synthetic DNAs Encoding NP-GT8 and IL-12, With or Without a TLR-agonist- Adjuvanted HIV Env Trimer 4571 Boost, in Adults Without HIV

National Institute of Allergy and Infectious Diseases (NIAID)·interventional·Posted Mar 23, 2023·Updated Nov 14, 2025

In Brief

A Phase 1 clinical trial evaluating sD-NP-GT8 DNA, IL-12 DNA, and 3 other interventions for HIV Infections. Completed, enrolled 46 participants across 8 sites in 2 countries.

Detailed Summary

This is an open-label study to examine the safety and immunogenicity of synthetic DNAs encoding NP-GT8 and IL-12 with or without a TLR-agonist-adjuvanted Env Trimer 4571 boost in adults without HIV. The primary hypothesis is that vaccination with this recombinant DNA vaccine encoding a germline-targeting epitope followed by a trimeric protein boost will elicit VRC01-class B-cell responses as well as antigen-specific T-cell responses.
