Official title
An Open Label Study to Evaluate Innate Immune Responses Induced by a Pattern Recognition Receptor Agonist, Poly-ICLC (Hiltonol), in Healthy Volunteers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Vaccines induce protective immunity against numerous infectious diseases. However, current vaccines have limited efficacy against challenging infections like tuberculosis, malaria, and HIV. Protein vaccines are safe but, typically they induce weak T cell immunity when administered alone. Therefore, special attention is being given to adjuvants, which are enhancers of immunity, that cab mature antigen presenting immunostimulatory dendritic cells. Our goal is to study in humans the mechanism whereby a synthetic adjuvant, poly ICLC, which acts on defined pattern recognition receptors, enhances T an B cell immunity. In preclinical studies, our lab has found in mice that poly IC and its analog poly ICLC are superior adjuvants for T cell mediated immunity relative to other agonists for PRR. Poly ICLC has been extensively studied in humans with a favorable safety profile. In a recently completed Phase I study, poly ICLC was found to be safe and well tolerated when administered as a single dose of 1.6 mg subcutaneously and intranasally to healthy volunteers. In additional, preliminary data shows marked upregulation of gene expression in whole PBMSc following s.c. injection of poly ICLC as well as activation of various blood cell type, including dendritic cells and monocytes. In this study the investigators propose to extend the evaluation of innate immune responses following s.d. injection of poly ICLC to healthy volunteers. The investigators propose to characterize poly ICLC effects on specific blood cell types, focusing on three different subsets of DC's, by analyzing gene transcriptional changes at baseline and at one day following its administration. In order to study the early local effects of poly ICLC, which are important for the recruitment and activation of antigen presenting cells, the investigators also propose to perform skin biopsies at a skin site contralateral to the injection site and at the injection site after poly ICLC injections.
