Summary of findings

Alden_2011

Carcinogenicity

Out of 287 registered drugs that were tested in rats and mice for carcinogenicity, results were concordant with humans for 146

Allen_1988

Carcinogenicity

Correlation of carcinogenic dose between animals and humans ranged from 0.49 to 0.90 depending on the analysis

Bailey_2013

Safety

All likelihood ratios (LRs) are larger than 1, indicating predictive value of the experiments in dogs. Inverse negative LRs (iNLRs) are very small, indicating relatively limited predictive value of negative results in dogs for humans. Positive LRs (PLRs) for dogs are large; if toxicity is observed in dogs, it is likely to occur also in humans. There is no correlation between positive predictive values (PVVs) and PLRs

Bailey_2014

Safety

All LRs are larger than 1, indicating predictive value of the experiments in rats, mice and rabbits. iNLRs are very small, indicating relatively limited predictive value of negative results in these species for humans. PLRs for these species are large; if toxicity is observed in rats, mice or rabbits, it is likely to occur also in humans. Both PLR and iNLR depend on sample size

Bailey_2015

Safety

All LRs are larger than 1, indicating predictive value of the animal experiments. iNLRs are very small, indicating relatively limited predictive value of negative results in animals for humans. PLR for non-human primates (NHPs) is large; if toxicity is observed in NHP, it is likely to occur also in humans

Brown_1983

Teratogenicity

Correct positives: 30–97%; correct negatives: 35–80%; animal to human lowest effective dose ratio: 1.8–50

Claude_2007

Adverse events

70% of human adverse events was predicted by animal models. Predictivity is higher for non-rodents than rodents. Predictivity was highest for haematological and cardiovascular, and lowest for cutaneous and ophthalmological adverse events

Crouch_1979

Carcinogenicity

Data for carcinogenic potency correlated

Davis_1998

QT prolongation

Out of 9 noncardiac drugs that show QT prolongation in humans, literature on dog cardiac effects was found for 7; 6 showing QT prolongation, 1 showing increased mortality

Ennever_2003

Carcinogenicity

Sensitivity appears to be high, but the lifetime rodent bioassay lacks accuracy. Sensitivity decreases if only results that are positive in both rats and mice are considered positive. The LRB produces many false positives and false negatives

Fletcher_1978

Adverse events

Correlations between animal toxicity and human adverse events are considerably more frequent than discrepancies. Gastro-intestinal adverse events show the best correlation

Fourches_2010A

Drug-induced liver injury

The concordance of liver effects between rodents and humans (44%) and between non-rodent species and humans (40%) was low

Freireich_1966

Toxic dose

Results in preclinical tests correlate remarkably well with results in man

Goodman_1991

Carcinogenicity

For 18 out of 20 examined chemicals with sufficient evidence, human and rodent evidence are consistent

Hoffmann_2018

Skin sensitization

Overall accuracy in skin sensitization prediction from animal to human was 74%, which decreased to 45% when considering five categories of potency

Igarashi_1995

Adverse events

Out of 31 pharmacological items tested after systemic administration, 17 showed a significant association with any clinical adverse reaction

Litchfield_1961A

Adverse events

18 out of the 53 physical signs observed in man were predicted correctly in rats; 29 out of the 53 in dogs

Litchfield_1962

Adverse events

Out of the 86 physical signs analysed in animals, 64 accurately reflected occurrence or absence in man

Monticello_2017

Adverse events

Excluding subjective adverse events, for rodents, PVV ranged from 0 to 54% and NPV ranged from 69 to 96%; for dogs, PVV ranged from 0 to 52% and NPV ranged from 76 to 96%; and for monkeys, PVV ranged from 0 to 91% and NPV ranged from 70 to 100%

Olson_2000A

Adverse events

In any species tested, 71% of human adverse events was predicted. Predictivity is higher for non-rodents than rodents. Predictivity was highest for haematological, cardiovascular and gastrointestinal toxicities, and lowest for cutaneous toxicities

Schein_1970

Adverse events

For the prediction of certain adverse event in humans, administration of highly toxic dose levels to animals is needed

Schein_1973a

Adverse events

For most organ systems, combining dog and monkey data reduces false negatives for prediction of human adverse events for anticancer drugs

Schein_1973b

Adverse events

Correct predictions of anticancer drug-induced adverse events are accompanied by a high percentage of false positives

Schein_1975

Adverse events

Results from 13 additional drugs generally overlap with the preceding analysis

Tamaki_2013

Adverse events

37% of adverse drug reactions in humans were predicted from animal studies

VanMeer_2012

Severe adverse reactions

Performed animal studies are not sensitive enough to predict post-marketing serious adverse reactions

Weaver_2003

Adverse events

No significant associations were observed between human and guinea pig data

Wilbourn_1986

Carcinogenicity

Sensitivity for the predictivity of animals for human carcinogenicity is high (84%), and there is good consistency between animals and humans in target organs
