TEST ANIMALS
- Source: Charles River Deutschland, Sulzfeld, Germany
- Age at study initiation: young adult animals (approx. 9-10 weeks old)
- Weight at study initiation: 160-190 g, body weight variation did not exceed ± 20% of the sex mean
- Fasting period before study: animals were deprived of food overnight prior to dosing and until 3-4 h after administration of the test substance, water was available
- Housing: group housing of 3 animals per cage in labeled Macrolon cages (MIV type; height 18 cm.) containing sterilized sawdust as bedding material (Litalabo, S.P.P.S., Argenteuil, France) and paper as cage-enrichment (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd), Surrey, UK).
- Diet: pelleted rodent diet (SM R/M-Z from SSNlFF® Spezialdiaten GmbH, Soest, Germany), ad libitum
- Water: tap water, ad libitum
- Acclimation period: at least 5 days

ENVIRONMENTAL CONDITIONS

Vehicle:
polyethylene glycol
Details on oral exposure:
VEHICLE
- Concentration in vehicle: 200 mg/mL
- Amount of vehicle (if gavage): 10 mL/kg bw
- Justification for choice of vehicle: the vehicle was selected based on trial formulations performed at the testing labotatory and on test substance data supplied by the sponsor.

3
Control animals:
no
Details on study design:
- Duration of observation period following administration: 14 days
- Frequency of observations and weighing: mortality: twice daily; clinical observations: daily; bodyweight: Day 1, 8 and 15
- Necropsy of survivors performed: yes
- Other examinations performed: clinical signs, body weight
Statistics:
No statistical analysis was performed (The method used is not intended to allow the calculation of a precise LD50 value).
