Automated animal models in a 3 Rs perspective.
� The 3R principle (replace, reduce, refine) has its origins with William M. S. Russell & Rex L. Burch, who published their “Principles of Humane Experimental Technique” in 1959. These principles are regarded internationally as the guideline for avoiding or reducing animal experiments and the suffering of laboratory animals:
� Replacement: replacement of animal experiments by methods that do not involve animals
� Reduction: reduction in the number of animals in unavoidable animal experiments
� Refinement: improvement in experimental procedures, in unavoidable animal experiments

The Basel Declaration
27-08-2012 Henrik Johansen 19
� “The Basel Declaration was issued on 30 November 2010 by over 60 scientists from Switzerland, Germany, the United Kingdom, France and Sweden. The signatories commit to accepting greater responsibility in animal experiments and to intensive cooperation with the public in the form of a dialogue with prejudice. At the same time, they demand that essential animal experiments for obtaining research results remain permitted both now and in the future. With their Basel Declaration, researchers are seeking to achieve a more impartial approach to scientific issues by the public and a more trusting and reliable cooperation with national and international decision makers.”

Conclusions from pilot study (n=2)
27 August 2012 H. Hansen, B. H. Bentzen 35
� The effect of acute sibutramine treatment of telemetrized rats reflects findingsin human subjects with respect to:- appetite suppression- increased blood pressure and heart rate
� In this acute setting, sibutramine did not affect diastolic blood pressure,suggesting that subchronic or chronic dose settings may be required to detectsignificant effects on this parameter
� The integration of HM-2 and DSI telemetry system provides data with extremelyhigh data and temporal resolution
� The integrated HM-2:DSI telemetry system can detect even minor changes inphysiological endpoint parameters
� The pilot study was conducted in normal-weight rats, hence, the physiologicaleffects monitored in the HM-2:DSI telemetry system may be more pronouncedin obese rats
Confidential
Findings, pilot study (n=2)
� Dose level of sibutramine (7.5 mg/kg, p.o.) is reported being a typical dose usedin a series of research papers
� The parent compound sibutramine is a dual SNRI
� Sibutramine (racemate of R- and S-form) is metabolized in the liver to producemetabolites being potent triple MRIs, with the R-enantiomers being most potent,i.e. R-desmethylsibutramine (Tmax 2.3h, T½ 4.2h) and R-didesmethylsibutramine(Tmax 2.7h, T½ 7.9h) (Noh et al., Arch Pharm Res 33(2):267-273, 2010).
� Sibutramine produces a strong anorectic response in telemetrized rats, lastingfor up to 48 hrs (PPP slides 3-5), likely reflecting the DMPK proporties ofsibutramine
� Sibutramine increases systolic (peak effect of +9 mm Hg) and mean (peak effectof +6 mm Hg), but not diastolic, blood pressure over at least 48 hrs
� Sibutramine increases heart rate (peak effect of +48 bpm) over 24 hrs
� Sibutramine slightly affects core body temperature
� No significant effect on motility
