A phase II, observer-blind, randomised, placebo-controlled, adjuvant-dose selection, multicenter prophylactic vaccination study to evaluate the immunogenicity and safety of GSK Biologicals’ herpes zoster vaccine, gE/AS01B, in comparison to gE combined with ½ dose AS01B adjuvant (gE/AS01E), to unadjuvanted gE (gE/Saline), and to Saline (placebo) when administered twice in subjects aged 50 years and older

Herpes zoster or shingles is caused by the reactivation of latent varicella-zoster virus (VZV). The incidence of HZ increases with age, presumably due to waning cellular immunity. GSK Biologicals’ candidate HZ vaccine, gE/AS01B, consisting of VZV glycoprotein E (gE) adjuvanted with AS01B has been evaluated in previous studies. The present study will provide comparative data concerning the immunogenicity and safety of 50 mg gE adjuvanted with different doses of AS01B, i.e., full dose AS01B, ½ dose AS01B (= AS01E), and no adjuvant when administered twice (Months 0 and 2) in adults ³ 50 YOA, and will include a Saline group as a negative control (placebo).
A phase II, single-blind, randomized, controlled, multicentre vaccination study to evaluate the safety and immune response of the GSK Biologicals Zoster vaccine, gE/AS01B, and to compare 3 doses of gE with AS01B adjuvant in healthy elderly subjects, aged 60 to 69 years and 70 years and above60 to 69 years and 70 years and above

The safety and immunogenicity of the Varicella Zoster virus (VZV) gE (50 µg)/AS01B vaccine has been evaluated in a previous study. This study intends to compare the immunogenicity and safety of different doses of gE (25, 50 and 100 µg) with AS01B adjuvant and of different schedules of administration (1 vaccination with 100 µg of gE versus 2 vaccinations with different doses of gE) in the healthy elderly (? 70 years) population. Subjects aged 60-69 years will also be enrolled to evaluate the safety and immunogenicity of the vaccine formulations in that age group. A control group vaccinated with 100 µg gE antigen with saline will be included to support justification of the adjuvant.

Study ZOSTER-006 will provide pivotal data on the overall efficacy in prevention of herpes zoster (HZ) in subjects ≥ 50 YOA. The primary endpoint of this study will be overall HZ vaccine efficacy (VE) across all age cohorts. To this end, ZOSTER-006 will evaluate VE of the gE/AS01B vaccine compared to placebo in reducing the risk of developing HZ in subjects ≥ 50 YOA. This study will enrol subjects in the age ranges 50-59 YOA, 60-69 YOA, 70-79 YOA and ≥ 80 YOA.
A phase 2 partially observer-blind randomized controlled multi-center dose-ranging and formulation-finding study of a new Novartis Meningococcal B Recombinant Vaccine evaluating the safety and immunogenicity when given concomitantly with routine vaccines in 2-month-old infants

Supported by the Novartis, 2009–2010 (Project No.: 2009-010106-11)
This study is aimed at assessing the safety and immunogenicity of different doses and formulations (including decreasing OMV contents) of a new Novartis Meningococcal B Recombinant Vaccine (rMenB + OMV NZ) in order to optimize its safety profile while maintaining sufficient immunogenicity. In addition, this study will assess whether prophylactic administration of paracetamol can decrease the incidence of febrile reactions following vaccination without impacting the immunogenicity of rMenB + OMV NZ and the routine infant vaccines.

Supported by the Czech Republic Grant Agency, 2014–2016 (Project No.: GA14-10233S)
The increasing number of pathogenic strains of microorganisms resistant to different types of antibiotics has become a major current medical problem. Secondary metabolites of hops (Humulus lupulus) have been recently described in many studies as potent antimicrobial agents against a range of microorganisms. The aim of this project is to broaden the scope of biomedical applications of these compounds, especially prenylflavonoids. For this reason, a profiling method for highly detailed metabolomic study of many hops varieties using UHPLC-Q/Orbitrap method will be developed. The structures of unknown and little known metabolites will be elucidated. Antimicrobial effects of crude extract, separated fractions and purified metabolites will be studied on various strains of viruses, aerobic bacteria, facultative anaerobic bacteria, and anaerobic bacteria. State-of-the-art sample pre-treatment techniques (for example QuEChERS) will be used for sample purification and pre-concentration.

Supported by the Czech Republic Ministry of Internal Affairs, 2012–2015 (Project No.: VF20122015024)
The aim of the project is to develop the methodological procedures for the isolation of bacterial and viral nucleic acids and protein and no-protein toxins from natural matrices, and the procedures for their identification and typing. In the case of bacteria and viruses are designed following the methodological procedures and specific technological and laboratory units: the acquisition and cultivation of biological agents, isolation of genome and plasmid DNA, or RNA in the case of a virus, the methodology and procedures for the preparation of samples of bacterial and viral nucleic acids from complex matrices, design of qPCR primers, probes and the reaction conditions and testing and validation of the proposed methods and procedures for the identification of biological agents. For the detection of low molecular weight toxins will be used high performance liquid chromatography coupled with tandem mass spectrometry and for detection and identification of protein toxins will be used mass spectrometric method SRM (Selected reaction monitoring).
