Utilizing transiently transfected cell lines could significantly reduce manufacturing timelines for protein subunit vaccines. This trial compared safety and immunogenicity of human immunodeficiency virus (HIV) envelope CH505TF gp120 vaccines produced by upstream stable and transient transfection (each admixed with GLA-SE adjuvant, a TL4 agonist). Both vaccines were safe and well tolerated.

Background: Multiple broadly neutralising monoclonal antibodies (mAbs) are in development for HIV-1 prevention. The aim of this trial was to test the PGT121.414.

As a result, understanding immunologic variation across individuals in response to vaccination is important for developing next-generation efficacious vaccines. Accurate outcome prediction and identification of predictive biomarkers would represent a significant step towards this goal.
View Article and Find Full Text PDFBackground: The neonatal immune system is uniquely poised to generate broadly neutralizing antibodies (bnAbs) and thus infants are ideal for evaluating HIV vaccine candidates. We present the design and safety of a novel glucopyranosyl lipid A (GLA)-stable emulsion (SE) adjuvant admixed with a first-in-infant CH505 transmitter-founder (CH505TF) gp120 immunogen designed to induce precursors for bnAbs against HIV.
Methods: HVTN 135 is a phase I randomized, placebo-controlled trial of CH505TF+GLA-SE or placebo.
