Clinical Trial to Evaluate the Safety and Immunogenicity of a Priming Regimen of 426c.Mod.Core-C4b Followed by HxB2.WT.Core-C4b Boosts, Both Adjuvanted With 3M-052 AF + Alum, in Adult Participants Without HIV and in Overall Good Health (NCT06796686)

A Phase 1 Clinical Trial to Evaluate the Safety and Immunogenicity of a Priming Regimen of 426c.Mod.Core-C4b Followed by HxB2.WT.Core-C4b Boosts, Both Adjuvanted With 3M-052 AF + Alum, in Adult Participants Without HIV and in Overall Good Health

๐ŸŸข Recruiting Phase1 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This is a partially randomized, open-label phase 1 study to evaluate the safety and immunogenicity of a priming regimen of 426c.Mod.Core-C4b adjuvanted with 3M-052 AF + Alum followed by boosts with HxB2.WT.Core-C4b adjuvanted with 3M-052 AF + Alum. The primary hypothesis is that the boosting with HxB2.WT.Core-C4b adjuvanted with 3M-052 AF + Alum will further mature broadly neutralizing antibody (bnAb)-precursor B-cell lineages elicited by 426c.Mod.Core-C4b adjuvanted with 3M-052 AF + Alum. 426c.Mod.Core-C4b adjuvanted with 3M-052 AF + Alum has been tested in HVTN 301 previously, whereas the HxB2.WT.Core-C4b will be first-in-human (FIH).
