6. Summary
6.1. Summary Results
The aim of this study was to assess possible health hazards of the test item Vires5 which could arise from repeated exposure via oral administration to rats over a period of 14 days and also to provide a basis for the selection of dose levels for a 28- day repeated dose oral toxicity study.
The test item was administered orally in graduated doses to 3 groups of male and female Wistar rats, Crl: WI(Han) (Full Barrier) by oral gavage using a gavaging canula. Each group comprised 3 males and 3 females.
One group received the vehicle water which served as control. The application volume was 5 mL/kg body weight.
The animals were treated with the test item 7 days per week for a period of 14 days. For each animal the individual dosing volume was calculated on the basis of the body weight most recently measured.
All surviving animals were sacrificed on day 15 and were subjected to a detailed gross necropsy. All animals found dead, moribund or intercurrently sacrificed were subjected to a gross necropsy. The wet weight of the organs was taken from all terminally sacrificed animals as soon as possible. Haematological and clinical biochemistry examinations were made on blood samples obtained from animals. A histopathological evaluation was carried out on all animals of all groups which were sacrificed at the end of the treatment period.
There was no test item-related mortality and no effect of Vires5 on the health condition of the animals was noted. No findings were recorded for body weight development, food consumption, haematology, and clinical biochemistry parameters analyzed. Macroscopic findings were incidental and not related to the test item. Slight differences in spleen and thymus weight are not assumed to be test item related. No histopathological findings were noted that could be related to Vires5.
6.2. Conclusion
On the basis of the present study, a 14-day Repeated dose oral toxicity study with Vires5 in male and female rats, with dose levels of 30, 300 and 1000 mg/kg/day the following conclusions can be made.
None of the dose levels used in this study was associated with any sign of toxicity. Therefore the limit dose of 1000 mg/kg bw can be recommended to be used in the high dose group of higher tier studies (e.g. 28-day oral repeated dose toxicity study).

7. Introduction
7.1. Justification for the Selection of the Test System
This test is performed on the rat. Although several mammalian species may be used, the rat is the preferred rodent species.
This study provides information on the possible health hazards which could arise from repeated exposure via oral administration to rats over a period of 14 days. As a dose range finding study, it should provide a basis for the selection of dose levels to be used in a 28-day repeated dose oral (gavage) toxicity study.
The test item is administered daily in graduated doses to 3 groups of test animals, one dose level per group for a treatment period of 14 days. During the treatment period, the animals are observed each day for signs of toxicity. Animals which die or are humanely sacrificed in a condition of impending or predictable death are subjected to necropsy. At the conclusion of the test, the surviving animals are sacrificed and subjected to necropsy.
7.2. Justification for the Selection of the Test Method No validated in vitro method is available for assessing systemic toxicity after repeated exposure.

9. Results
9.1. Mortality
For a summary see Table 5.
There was no test item related mortality in this study.
9.2. Clinical Observation
For a summary see Table 6; for a detailed description of the individual findings see Tables 26 and 27.
On the day of necropsy piloerection was noted in 2 female animals of the high dose group. This was, however, not associated with any other pathological signs. None of the male animals of this group was affected. Thus this slight finding is not assumed to be related to the test item. With the exception of transient nasal discharge in one animal of the mid dose group, which is not assumed to be test item related, there were no clinical findings in this study
9.3. Body Weight and Body Weight Change
For group means see Tables 8, 9, 10 and 11; for individual data see Tables 28, 29, 30 and 31.
Vires5 did not have any effect on body weight development in this study. Throughout the treatment period body weights of male and female animals of all groups were in the normal range of variation for this strain and age. There were no considerable differences in body weight between any of the dose groups and the control group.
9.4. Food Consumption For group means see Tables 12 and 13; for individual data see Tables 32 and 33.
Vires5 did not affect food consumption in this study. There were no biologically relevant differences in food intake between any of the dose groups and the control group.
9.5. Haematology For group means see Tables 14 and 15; for individual data see Tables 34 and 35.
All haematological parameters analyzed in this study were in the normal range of biological variation for this strain. There were no considerable differences, neither in red cell parameters (RBC, haematocrit, haemoglobine) nor in white blood cells or platelets when comparing dose groups to control group.
9.6. Clinical Biochemistry For group means see Tables 16 and 17; for individual data see Tables 36 and 37.
Report, BSL BIOSERVICE Study No. 112936 page 20 of 110 Version: Final
All clinical pathology parameters analyzed at the end of the treatment period were within the normal range of variation for this strain. There were no considerable differences between dose groups and control group.
9.7. Gross Pathology
For a summary see Tables 18 and 19; for a detailed description of the individual findings see Tables 38 and 39.
After 14 days of oral treatment with Vires5 only one or few mild findings were noted that are assumed to be incidental and not related to the test item. One male animal of the low dose group had a discolored red stomach, which was not associated with any histopathological findings in this organ. On the epididymides of two male animals (one from the low dose group and one from the high dose group), yellow foci were found – a common background finding in this strain. One male animal of the high dose group had blood on the surface of the brain and 2 male animals (one of the medium dose group and one of the high dose group) had a cyst on the adrenals. These single mild findings are not assumed to be related to the test item.
One female control animal of the low dose group had a thickened mucosa in the stomach, which was not associated with any histopathological findings in this organ.
9.8. Organ Weight
For group means see Tables 20 to 25; for individual data see Tables 40 to 45.
The absolute and relative spleen weight of the spleens of the male animals of the high dose group was slightly lower than in controls. As this slight difference in spleen weight was not observed in female animals and due to the low number of animals, this is not assumed to be related to the test item.
A tendency towards a lower thymus weight was also observed in Vire5 treated male animals of this study, however, not dose-dependently. Due to the slight degree, the low number of animals and the fact that female animals were not affected, a relation to the test item is doubtful.
Besides, there were no considerable differences in organ weights of Vires5 treated animals when compared to controls.
9.9. Histopathology
Histopathological findings noted in the organs evaluated were very few and none of them was considered to be test item-related.

10. Conclusion
On the basis of the present study, a 14-day Repeated dose oral toxicity study with Vires5 in male and female rats, with dose levels of 30, 300 and 1000 mg/kg/day the following conclusions can be made.
None of the dose levels used in this study was associated with any sign of toxicity. Therefore the limit dose of 1000 mg/kg bw can be recommended to be used in the high dose group of higher tier studies (e.g. 28-day oral repeated dose toxicity study).
