(author), Alves, T. (author), Carrondo, M. (author), Peixoto, C. (author), Peeters, P.A. (author), Vaes, W.H. (author)Preclinical development of new biological entities (NBEs), such as human protein therapeutics, requires considerable expenditure of time and costs. Poor prediction of pharmacokinetics in humans further reduces net efficiency. In this study, we show for the first time that pharmacokinetic data of NBEs in humans can be successfully obtained early...article 2015

van Duijn, E. (author), Sandman, H. (author), Grossouw, D. (author), Mocking, J.A.J. (author), Coulier, L. (author), Vaes, W.H.J. (author)The increasing role of accelerator mass spectrometry (AMS) in biomedical research necessitates modernization of the traditional sample handling process. AMS was originally developed and used for carbon dating, therefore focusing on a very high precision but with a comparably low sample throughput. Here, we describe the combination of automated...article 2014

(author)Results: Ten infants (aged 0.1–83.1 months) were included; one was excluded as he vomited shortly after administration. In nine patients, [14C]AAP and metabolites in blood samples were detectable at expected concentrations: median (range) maximum concentration (Cmax) [14C]AAP 1.68 (0.75–4.76) ng/L, [14C]AAP-Glu 0.88 (0.34–1.55) ng/L, and [14C...article 2014

Buscher, B.A.P. (author), Jägfeldt, H. (author), Sandman, H. (author), Brust-van Schaik, R. (author), van Schaik, F. (author), Brüll, L.P. (author)A bioanalytical method for the quantitative determination of budesonide and fluticasone in human sputum was developed. Sputolysin ® Reagent was added to the sputum samples. After incubation (37°C; 60-70min under shaking) and automated solid phase extraction the extracts were analysed using LC-MS/MS. Budesonide and fluticasone showed good...article 2012
