- Details on study design:
- The 2000 mg/kg dose is specified by regulatory agencies for the limit test. Any additional doses were selected to estimate the LD50.The test article was administered once on Day 1 via oral gavage to one animal. The initial dose level for the sighting study was 2000 mg/kg. Due to there being no toxicity noted, an additional animal was administered the test article at a dose level of 5000 mg/kg. The results of the sighting study determined that 5000 mg/kg was the starting dose for the main study animals. Individual doses were based on the most recent body weight measurements. The test article was administered at a dose volume of 2.08 mL/kg to the initial animal dosed in the sighting study and at a dose volume of 5.21 mL/kg for the second animal in the sighting study and for all main study animals. The animals were fasted overnight prior to test article administration and had food returned following the completion of dosing.Observations for morbidity, mortality, injury, and the availability of food and water were conducted twice daily for all animals. Observations for clinical signs were conducted on Day 1 at 30 minutes, 2, and 4 hours postdose, and daily thereafter. Body weights were measured and recorded prior to dosing on Day 1 and weekly thereafter.At study termination (Day 15), the animals were euthanized by carbon dioxide inhalation. Euthanasia was confirmed via exsanguination via severing the vena cava. Necropsy examinations were performed under procedures approved by a veterinary pathologist on all animals euthanized at the scheduled necropsy. The animals were examined carefully for external abnormalities including palpable masses. The skin was reflected from a ventral midline incision, any subcutaneous masses were identified and correlated with antemortem findings, and the abdominal, thoracic, and cranial cavities were examined. Following the evaluation, the carcasses were discarded and no tissues were saved.

- Executive summary:
This study was conducted for the sponsor to evaluate the potential oral acute toxicity of the test article, Hatcol 3346. This study was conducted in accordance with Standard Operating Procedures (SOPs) and the protocol as approved by the Sponsor. No protocol or SOP deviations occurred. This study was based on the Organization for Economic Cooperation and Development (OECD) Guideline 420 (2001) and the Guide for the Care and Use of Laboratory Animals, Institute of Laboratory Animal Resources, National Academy Press, Washington, D.C., 2011.
The 2000 mg/kg dose is specified by regulatory agencies for the limit test. Any additional doses were selected to estimate the LD50.
The test article was administered once on Day 1 via oral gavage to one animal. The initial dose level for the sighting study was 2000 mg/kg. Due to there being no toxicity noted, an additional animal was administered the test article at a dose level of 5000 mg/kg. The results of the sighting study determined that 5000 mg/kg was the starting dose for the main study animals. Individual doses were based on the most recent body weight measurements. The test article was administered at a dose volume of 2.08 mL/kg to the initial animal dosed in the sighting study and at a dose volume of 5.21 mL/kg for the second animal in the sighting study and for all main study animals. The animals were fasted overnight prior to test article administration and had food returned following the completion of dosing.
Observations for morbidity, mortality, injury, and the availability of food and water were conducted twice daily for all animals. Observations for clinical signs were conducted on Day 1 at 30 minutes, 2, and 4 hours postdose, and daily thereafter. Body weights were measured and recorded prior to dosing on Day 1 and weekly thereafter.
At study termination (Day 15), the animals were euthanized by carbon dioxide inhalation. Euthanasia was confirmed via exsanguination via severing the vena cava. Necropsy examinations were performed under procedures approved by a veterinary pathologist on all animals euthanized at the scheduled necropsy. The animals were examined carefully for external abnormalities including palpable masses. The skin was reflected from a ventral midline incision, any subcutaneous masses were identified and correlated with antemortem findings, and the abdominal, thoracic, and cranial cavities were examined. Following the evaluation, the carcasses were discarded and no tissues were saved.
All animals survived to the scheduled necropsy.
No adverse clinical findings indicative of systemic toxicity were noted. Yellow discoloured hair was noted in the anogenital region on Day 1 at 4 hours postdose for animal number 8002. This is a common finding in an animal of this age, sex, and strain, thus deemed not test article-related.
There were no adverse test article-related effects on body weight. Body weights were within normal range for this species.
The tissues of all animals examined at necropsy were within normal limits.
Under the conditions of this study, where Hatcol 3346, was administered as a single oral dose to rats, the LD50 was greater than 5000 mg/kg. No classification is applicable.

Recognised by international guidelines as the recommended test system (e.g.OECD, EC)Source: Charles River Deutschland, Sulzfeld, Germany.Number of animals: 5 males and 5 females (females were nulliparous and nonpregnant).Age and bodyweight: Young adult animals (approx. 9-10 weeks old) were selected. Bodyweight variation did not exceed +/- 20% of the sex mean.Identification: EarmarkConditionsAnimals were housed in a controlled environment, in which optimal conditions were considered to be approximately 15 air changes per hour, a temperature of 21.0:i 3.0°C (actual range: 17.2 - 23.7°C), a relative humidity of 30-70% (actual range: 44 - 83%) and 12 hours artificial fluorescent light and 12 hours darkness per day. Cleaning procedures in the room might have caused the temporary fluctuations above the optimal maximum level of 70% for relativehumidity. Based on laboratory historical data, these fluctuations were considered not to have affected the study integrity.AccommodationIndividually housed in labelled Macrolon cages (type IIi, height 15 cm.) containing purified Sawdust as bedding material (SAWI, Jelu Werk, Rosenberg, Germany). Certificates of analysis were examined and then retained in the NOTOX archives. Acclimatisation period was at least 5 days before start of treatment under laboratory conditions.DietFree access to standard pelleted laboratory animal diet (from Altromin (code VRF 1), Lage, Germany). Cer!ifcates of analysis were examined and then retained in the NOTOX archives.WaterFree access to tap-water. Certifcates of quarterly analysis were examined and then retained in the NOTOX archives.

Additional information
No clinical signs of toxicity and with regard to gross pathology no signs of systemic toxicity and no abnormalities were observed. The acute toxicity of the substance is summarised as follows:
Oral
All animals survived to the scheduled necropsy.
No adverse clinical findings indicative of systemic toxicity were noted. Yellow discoloured hair was noted in the anogenital region on Day 1 at 4 hours postdose for animal number 8002. This is a common finding in an animal of this age, sex, and strain, thus deemed not test article-related.
There were no adverse test article-related effects on body weight. Body weights were within normal range for this species.
The tissues of all animals examined at necropsy were within normal limits.
Under the conditions of this study, where Hatcol 3346, was administered as a single oral dose to rats, the LD50 was greater than 5000 mg/kg. No classification is applicable.
Inhalation.
In accordance with column 2, adaptation of Annex VIII (section 8.5.2) testing by the inhalation route is deemed inappropriate as exposure to humans via inhalation is unlikely to occur as the substance does not have a high vapour pressure, and will not be used in a manner likely to produce significant aerosols or droplets of an inhalable size. The dermal route is considered to be a more appropriate second route of exposure, and sufficient data is available to address this endpoint.
Dermal
Read across to structural analogue.
No mortality occurred.
Hunched posture and/or chromodacryorrhoea were noted among all animals on day 2. In addition, maculate erythema or scales were seen on the treated skin site of one male and female between days 3 and 7. The body weight gain during the observation period was within the range expected for rats used in this type of study.
No abnormalities were found at macroscopic post mortem examination of the animals. The dermal LD50 value of HATCOL 3331 in Wistar rats was established to exceed 2000 mg/kg body weight.
Justification for selection of acute toxicity – oral endpoint
Recent study performed in accordance with OECD test guideline and in compliance with GLP.
