Filter by: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.
This Phase 1 study is being conducted to evaluate 3 increasing subcutaneous (SC) doses (50, mg, 100 mg or 200mg) of mipomersen in Japanese healthy volunteers. Eligible subjects will receive a single study injection of either mipomersen or placebo. Subjects will be enrolled into 1 of 3 treatment cohorts (Cohorts A, B, and C) in a dose-escalation design. Dose-escalation will proceed only if there is an acceptable safety profile from the previous dosing level.
This is a single dose study of radio-labeled [14C]-LY3009104 in healthy male volunteers to study the absorption, distribution, metabolism, and elimination of LY3009104. This study requires minimum of 7 days and maximum of 22 days stay. This study is for research purposes only and is not intended to treat any medical condition.
This study investigates whether mirabegron (YM178) has an effect on the pharmacokinetics of solifenacin and whether solifenacin has an effect on the pharmacokinetics of mirabegron.
The objective of this study is to determine the effect of multiple doses of mirabegron on the pharmacokinetics of an oral contraceptive.
Berry components have been shown to influence cancer processes in cell culture studies. The investigators will conduct a study to investigate if blackberries influence the same cancer processes in a human feeding study.
The purpose of this study is to evaluate the effect of an 800-mg single dose of TMC207 on the QT/QTc interval in healthy volunteers.
The objective of this proof of concept study is to assess the involvement of epoxy-eicosatrienoic acids (EETs) in post-occlusive hyperemic and thermal hyperemia responses, and the interaction between nitric oxide (NO) and EETs, using the latest methods for the study of functional microcirculation.
The purpose of this study is to assess the pharmacokinetics, safety, and tolerability of single oral doses of TMC649128 in healthy volunteers. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body, and eliminated from the body.
This will be a single-center, open-label, 3 part study. The study is designed to determine the relative bioavailability of GDC-0980 capsule and tablet formulations under fasting conditions, the effects of a high-fat (fed) meal on the pharmacokinetics of the GDC-0980 tablet, and the effects of rabeprazole on the pharmacokinetics of the GDC-0980 tablet in the presence or absence of a high-fat meal.
