Key value for chemical safety assessment
- Toxic effect type:
- dose-dependent
Repeated dose toxicity: via oral route - systemic effects
Link to relevant study records
- Endpoint:
- sub-chronic toxicity: oral
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- From 22 July 2015 to 14 December 2015
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Well performed GLP and OECD guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 408 (Repeated Dose 90-Day Oral Toxicity Study in Rodents)
- Principles of method if other than guideline:
- Devations:Deviation No. 1The weight in females (150.04-170.06 g) and some males (241.60-244.75 g) on day 1 of treatment were not within the range specified in the study plan (males: 198-238 g and females: 125 150 g). The weight of females at arrival was higher than expected and no study plan amendment was issued.Deviation No. 2The push-pull strain gauge to determine the grip strength used (BIOSEB GT3 no. BT0171) is not the same as that stated in the Study plan (Mecmesin, AFG 25N).Deviation No. 3On 23 July 2015 (day 2 of acclimatization), room temperature and humidity were not monitored for 7 minutes due to an incidence in the SCADA monitoring system.Values outside the established ranges for humidity (30-70%) occurred occasionally (around 95%).Deviation No. 4The blood sample obtained from some animals (1M, 4M, 12M, 43F, 52F) for coagulation parameters was coagulated and although the extraction was repeated, no results for PT or APTT are reported for animals 12M, 43F or 52F. The samples were coagulated again and not analyzed.The sample from females 67 and 68 was also coagulated and not analyzed; no repetitions were done to avoid obtaining more blood and therefore no results are reported for PT or APTT.Deviation No. 5A sample from the tongue was fixed in formalin solution and a slide prepared although this was not indicated in the study plan; therefore, it will not be examined histopathologically. Deviation No. 6Given the results of the dose formulation prepared at the low dose (19 October) and to be administered in week 13, a new analysis was done. New samples were taken and frozen on 27 October from a formulation prepared on 23 October. Aliquot 1 was analyzed, but it was not possible to analyze aliquot 2 (bottom) as, according to the Principal Investigator, the tube did not contain any sample although according to the raw data the sample had been taken. Given the nature and magnitude of these deviations, it can be stated that they did not alter the conclusions of the Study.

- Route of administration:
- oral: gavage
- Vehicle:
- water
- Remarks:
- prepared in-house with Milli-Q water purification system (MILLI Q Gradient A10 Century, Merck)
- Details on oral exposure:
- Dose Formulation PreparationThe dose formulations were prepared up to six days in advance. Dose levels were calculated based on the active ingredient. Granofin Easy F-90 was weighed in a glass beaker on a tared precision balance and approximately 80% of the vehicle was added (w/v). A homogeneous suspension was prepared using a magnetic stirrer. Having obtained a homogeneous mixture, the suspension was transferred to a volumetric flask and filled to the mark using the remaining vehicle. The formulation was transferred to a glass beaker and when there was enough vehicle left for the final formulation volume, it was used to clean the volumetric flask and was then added to the glass beaker.The total volume to be administered on several consecutive days was prepared (stock solution) in advance and the necessary amount aliquoted for each administration day.Homogeneity of the test item in the vehicle was maintained during the daily administration period using a magnetic stirrer.Dose formulations were stored in the refrigerator (5 ± 3 °C) in suitable glass containers appropriate for the administration. They were allowed to reach room temperature just before dosing.Based upon the results of stability analyses performed within the non-GLP Harlan Laboratories study D51272 14-Day Oral Toxicity (Gavage) Study in the Wistar Rat, dose formulations are stable for at least seven days if stored in the refrigerator.

- Observations and examinations performed and frequency:
- Viability / Mortality: Cage-side clinical observations were performed twice dailyClinical Signs: Detailed clinical signs were recorded on the first day of treatment and daily from the third day of administration. These observations we re done at the time of administration: Animals were observed for changes in skin, fur, eyes, mucous membranes, occurrence of secreti ons and excretions, and autonomic activity (e.g. lacrimation, piloerection, pupil size, and unusual respiratory pattern). Changes in gait, posture and response to handling as well as the presence of clonic or tonic movements, stereotypies or bizarre behavior were also che ckedFunctional Observational Battery (Sensory Activity, Grip strength assessment, Locomotor activity assessment), on the day of sacrifice, Days 85 and 86Food Consumption: Before treatment start (days 3-9 of the acclimatization period), and once a week during treatment periodBody Weight: Once before treatment start, once weekly during treatment and before sacrificeOphthalmoscopy (Cornea, lens, conjunctiva, sclera, iris and fundus): on Day 7 for all animals and on Day 89, just for group 4, because no treatment-r elated alterations were recorded in group 4. Clinical Laboratory Investigations (Hematology, Coagulation, Blood Biochemistry): on the day of sacrifice ( Days 91 and 92)Pathology (Sacrifice and Macroscopic Examinations, Organ Weights, Histopathology)
- Sacrifice and pathology:
- At the end of the treatment period, all surviving animals were deprived of food overnight and were deeply anesthetized with sodium pentobarbital administered intraperitoneally and then exsanguinated by excision of the axillary vessels and aorta.
- Statistics:
- The following statistical methods were used by the ToxControl system Version 8.0 to analyze body weight, food consumption, grip strength, locomotor activity, clinical laboratory data and organ weights and ratios as well as macroscopic findings:1.The Dunnett-test (many to one t-test) based on a pooled variance estimate was applied when the variables were assumed to follow a normal dist ribution for the comparison of the treated groups and the control groups for each sex (Dunnett, 1955).2.The Steel-test (many-one rank test) was applied instead of the Dunnett-test when the data could not be assumed to follow a normal distribution (Miller, 1981).3.Fisher's exact-test was applied to the macroscopic findings (Fisher, 1950).
- Clinical signs:
- effects observed, treatment-related
- Description (incidence and severity):
- The animals survived the scheduled treatment period. No clinical signs were recorded attributed to treatmentSlightly increased salivation was observed just after administration for a maximum of 5 minutes often during treatment in most group-4 animals and just once in five group-3 animals. Occasionally some of the animals from group 4 started to show the increase just before or during administration. Given the moment in which it was observed and the duration it is considered due to the handling rather than to an effect of the test item. Some animals from groups 3 (26M, 28M, 29M) and 4 (36M, 38M, 39M, 40M, 77F, 78F, 79F) showed a wound or scab and hypotrichosis and/or alopecia on an small area of the face. Female 66 (group 3) showed hypotrichosis in the abdominal area. In most of the cases, these alterations were observed from weeks 9-10 and were not observed at the end of treatment. Given that this sign is often observed in rats and given the incidence, they are not attributed to an effect of the test item.

- not specified
- Conclusions:
- Under the conditions of this study, oral administration of Granofin Easy F-90 to Wistar rats during 90 consecutive days did not induce alterations or toxicological effects. Therefore, the dose of 100 mg/kg/day is considered the NOEL (No Observed Effects Level).
- Executive summary:
- Granofin Easy F-90 wasadministered orally (by gavage) to Wistar rats once daily for 90 days. Four treatment groups were established, each containing 10 males and 10 females.
Animals from group 1 were administered with the vehicle (purified water) following the same dosing regimen as the groups treated with the test item and animals from groups 2, 3 and 4 with the test item at 5, 25 and 100 mg/kg, respectively.
Dose formulations prepared and administered in weeks 1 and 13 were analyzed for homogeneity and concentration.
After the treatment period, all animals were necropsied and various organs were weighed. Macroscopic alterations were recorded. A full set of tissues and organs was collected but only samples taken from groups 1 and 4 were processed and examined histopathologically. Samples form groups 2 and 3 were not processed or examined as no test item-related morphologic changes were detected in group 4.
The animals survived the scheduled treatment period.
No clinical signs or alterations in food consumption, body weights, sensory activity, grip strength, locomotor activity, hematology, coagulation and biochemistry parameters were recorded attributed to the treatment.
No treatment-related macroscopic or microscopic alterations or alterations in organ weights were observed.
