Study ID | Field of research | Summary of findings |
---|---|---|
Akabane_2010A | Absolute bioavailability | Bioavailability in cynomolgus monkeys is unsuitable for predicting PK in humans |
Bachmann_1989 | Clearance | Predicted values are in the same order of magnitude as actual values |
Bachmann_1996A | Volume of distribution | Human volume of distribution and half-life values can be predicted from those in rats |
Boxenbaum_1982A | Clearance | It is not possible to reasonably predict human pharmacokinetic parameters from knowledge of these parameters in dogs |
Caldwell_2004A | Clearance | There is a reasonable correlation between human and rat clearance and half-life; and a good correlation for volume of distribution, but only 52–65% of drugs show < twofold error. Go/no go decisions based on only rat data should be avoided |
Campbell_1994A | Clearance | Predictive accuracy for clearance from rat, dog and monkey is acceptable. The dog is a poorer predictor of clearance than the rat |
Cao_2006A | Oral bioavailability | Oral bioavailability does not correlate between rats and humans; R2 = 0.29 while intestinal permeability correlates better; R2 = 0.70 |
Cheng_2008 | Oral absorption | Human intestinal absorption cannot be precisely predicted by a single screening assay |
Chiou_1998A | Oral bioavailability | Oral bioavailability correlates between rats and humans, and to some extent between dogs and humans |
Chiou_2000a | Oral absorption | Similar gastrointestinal absorption may be obtained when doses in humans (/kg body weight) are 5–7 times lower than in rats |
Chiou_2000bA | Oral absorption | R2 = 0.51–0.90 for oral absorption between dogs and humans; plasma level peak times seem to be shorter for dogs. R2 = 0.95 for oral absorption between rats and humans. |
Chiou_2002A | Oral absorption | Oral absorption correlates well between monkeys and humans: R2 = 0.97; bioavailability correlates to some extent between monkeys and humans: R2 = 0.50; clearance correlates between monkeys and humans: R2 = 0.82; time to peak concentration was generally similar in humans and monkeys |
DeBuck_2007A | Volume of distribution | Predictions of plasma concentrations after oral dosing are reasonable. Prediction of volume of distribution improves when accounting for interspecies differences in plasma protein binding. 18 out of 19 drugs had a predicted half-life within twofold of the actual observed half-life |
Dong_2011A | Volume of distribution | For Monoclonal antibodies with non-linear kinetics, prediction is poor, with up to 6.3-fold differences |
Evans_2006 | Clearance, distribution volume and residence time | Percentages of correct predictions for clearance, distribution volume and residence time for rat, dog and monkey varied from 29 to 91%, and the average margin of error from 44 to 159%. The authors note that the outcomes are different from similar analyses of other compound datasets |
Fagerholm_1996 | Jejunal permeability | For passively absorbed compounds (n = 8), the correlation is high; R2 = 1.0. For passively absorbed compounds, rat permeability estimates can be used to predict human oral absorption |
Fagerholm_2007a | Fraction excreted unchanged | Out of 25 compounds, 11 had a fraction of 0 excreted unchanged in both humans and rats.
