Achieving the target plasma concentra-tions is challenging and often necessitates higher dosages, which increases the risk of adverse ef-fects. The formulation of pharmaceuticals with poor solubility is a complex and costly process that hinders overall drug development. Given the limitations of traditional formulation strategies to address these issues, it is essential to explore alternative methods. The innovative method of nano-crystallization enhances the solubility and dissolution rates of pharmaceuticals by reducing their particle sizes to the nanoscale.

Despite strong enthusiasm for this hypothesis, motivated in large part by its potential application to HIV-1 therapeutic strategies, the mechanism(s) underlying a vaccinal ef-fect remain unclear. Moreover, vaccinal effects on antibody and T cell responses are not consist-ently replicated. Partly, this inconsistency may be due to numerous difficulties in sensitively measuring a vaccinal effect in the context of human clinical trials. The magnitude of immune response increase following bNAb administration is generally modest, even when it is observed; a far greater enhancement of neutralization or T cell responses is likely required for a biologically meaningful impact. We review clinical and pre-clinical nonhuman primate studies that evaluated HIV-1/SIV monoclonal antibodies for vaccinal effects, with an emphasis on the strengths and limitations of these studies. Considerations for future studies investigating vaccinal effects are discussed, including appropriate comparators and specificity controls. Lastly, immune response characteristics of elite controller cohorts are outlined as potential vaccinal effect endpoints more likely to mediate HIV-1 suppression. As bNAb therapeutic interventions increasingly turn to combination approaches, including incorporation of immunomodulatory agents, attention to study design incorporating appropriate control groups, and relevant immunogenicity assays will enable more conclusive interpretation of vaccinal effects likely to mediate durable control of HIV.
