The small, the rare, and the complex

Analyzing challenging matrices

dropWhile many preclinical and clinical studies require analysis of plasma, serum or blood, some involve more challenging matrices, such as vitreous and aqueous humor, tears, synovial fluid, and bronchoalveolar lavage. These matrices often have high viscosity, high protein concentration and low analyte concentration. Added to that, the samples are almost invariably very small, expensive and difficult to source. Analytical methods must therefore match the matrix’s complex qualities and also the small volumes available.

Of mice and men (and pharmacokinetics)

Knock-in hMICE upgrade value of preclinical models

Of-mice-and-men-(and-pharmacokinetics)George Hu and his colleagues (1) at Pfizer have improved the predictive power of their pharmacokinetic (PK) models by replacing an anti-drug conjugate (ADC) target in mice with the human version, yielding more relevant data from their preclinical study. Their work focused on trophoblast glycoprotein (TPBG), a target of several therapeutic anti-tumor cancer agents currently in the development pipeline. Mice were engineered to express human TPBG. Hu’s group then studied the pharmacokinetics of a clinical-stage anti-TPBG ADC (A1mcMMAF) in wild-type mice and ‘knock-in’ hTPBG mice.

Award-winning modeling supports 3Rs

Non-vivo approach complements microsampling and lean sample analysis

3Rs of responsible research: Reduce, Refine, ReplaceThe importance of minimizing animal use was highlighted in the Nordic Prize for Alternatives to Animal Experiments 2014, awarded at the Digital Health Days conference, held in late August in Stockholm, to Christel Bergström, Maria Karlgren and Pär Matsson at Uppsala University for their contribution of animal-free methods in drug development. The team has used cell models and computer models to study intestinal drug transport, side effects and drug interactions. Using these screening and predictive methods prior to preclinical testing will aid drug design and identify benefits and risks early on, thus reducing animal testing.
