Description of key information
Skin irritation/corrosion - in vivo
SH-0850 is a "non-irritant".
Eye irritation - in vitro
The test item is not classified as a severe irritant and not classified as non-irritant. No conclusion of in vivo significance can be made from the adherence of the test item to the cornea, since in vivo eye lids may clear the surface, but abrasion may occur. It is concluded that an in vivo study is required for classification.
Eye irritation - in vivo
SH-0850 does not require classification as an eye irritant.

- Details on study design:
- Dosage
The test item was used as supplied, as a single dose of 0.5 g of SH-0850, applied to the test area. The untreated skin of each animal served as a control.
Application of the Test Item
Patch testing was used to detect primary irritating effects of the test item. Three male animals in acceptable health condition were selected for this test.
Approximately 24 hours prior to the test, the hair was clipped from the back and flanks of the animals. Removal of hair was performed in two steps. The majority of hair was clipped with an electronic hair clipper and the remaining hair was moistened with water and shaved with a razor.
The test item was applied to an approximately 6 cm² area of intact skin as follows:
• A single layer of a fine medical gauze (open-weave with large holes) of approximately 5x5 cm was placed over the application area,
• The appropriate amount of test item was carefully spread over the application area (the gauze helped maintain the test item in place),
• Three more layers of gauze were placed over the test item,
• These gauze patches were kept in contact with the skin by a patch of clear plastic with a surrounding adhesive hypoallergenic plaster to ensure continued good contact between the moistened test item and the shaved skin.
• The entire trunks of the animals were wrapped with plastic wrap for 4 hours.
• Medical elastic tubing was placed over the plastic to keep it in place.
An initial test was performed using one animal. One hour after application of the test item, the application site was examined. No severe irritation or corrosive effect was found in the initial test, therefore the bandage was replaced and the exposure continued for a further 3 hours (a total 4 hours exposure). Two additional animals were then included in the study.
Duration of Exposure
Duration of exposure: 4 hours. After the treatment period, the test item was removed with water at body temperature.
OBSERVATIONS AND SCORING
Clinical Observations
Animals were examined for signs of erythema and oedema, and the responses scored at 60 minutes and then at 24, 48 and 72 hours after patch removal.
Scoring and Assessment of Local Reactions
The dermal irritation scores were evaluated according to the scoring system by Draize (1959). The animals were observed for 72 hours and the duration of the study was sufficient to evaluate fully the reversibility or irreversibility of the effects observed.
Measurement of Body Weight
Body weights were recorded at the beginning and at the end of experiment.
Termination
At the end of the observation period, euthanasia of the animal was by intramuscular injections of CP-Ketamin 10 % and CP-Xylazin 2 % followed by i.v. RELEASE 300 mg/ml inj. A.U.V. anaesthesia (see details in 3.1.2.). Death was verified by checking pupil and cornea reflex, absence of respiration and pulse. - Irritation parameter:

An acute skin irritation study was performed with SH-0850 in New Zealand White rabbits. Parameters monitored during this study included mortality, body weight measurements and clinical observations. The irritancy of the test item was evaluated according to the Draize method (OECD No.: 404, 2002).
A weight of 0.5 g for solid test item was applied to the skin of the experimental animals. The test item was applied as a single dose. Sufficient water to damp the material was used to ensure good contact with the skin and an adhesive clear plastic patch was applied. The trunk was wrapped in clear plastic with medical tubing used to hold the patch in place. The untreated skin of each animal served as control.
After 4 hours, the remaining test item was removed with water at body temperature.
To assess skin irritation, animals were examined at 1, 24, 48 and 72 hours after the patch removal. Additional general examinations were performed daily.
There was no mortality or systemic clinical changes related to SH-0850 administration.
There was no effect of treatment on body weight.
At observation one, 24, 48 and 72 hours after patch removal, there were no observed clinical signs noted on the skin of the treated animals.
As no clinical signs were observed the study was terminated after the 72 hours observation.
The animals’ individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for erythema and oedema were 0.00, 0.00 and 0.00 respectively.

- Treatment
After the zero reference measurements, the eye (in its retainer) was removed from the chamber, and placed on a layer of tissue with the cornea facing upwards. The eyes were held in horizontal position, while the test item was applied onto the cornea. The test item was applied in an amount of 30 mg onto the entire surface of the cornea attempting to cover the cornea surface uniformly with the test substance, taking care not to damage or touch the cornea.
The positive control eyes were treated in a similar way with 30 mg powdered Imidazole. The negative control eye was treated with 30μL of Saline (Salsol solution, NaCl 0.9% w/v).
One eye was treated with isotonic saline, three eyes with the test item and another three ones with Imidazole.
Test item removal
The time of application was observed, then after an exposure period of 10 seconds from the end of the application the cornea surface was rinsed thoroughly with 20 mL isotonic saline at ambient temperature, taking care not to damage the cornea but attempting to remove all residual the test item if possible.
The test item and the Imidazole were stuck on the corneas’ surface after the post-treatment rinse. Gentle rinsing with 20 mL saline was performed and the rate of saline-drops was increased at each observation time point.
The test item treated cornea surfaces were cleared 75 minutes (1/3) or 120 minutes (1/3) or 240 minutes (1/3) after the post-treatment rinse.
The Imidazole treated cornea surfaces were not cleared 240 minutes after the post-treatment rinse.
Observation and assessment of corneal effects
The control eyes and test eyes were evaluated pre-treatment and at approximately 30, 75, 120, 180 and 240 minutes after the post-treatment rinse.
Minor variations within approximately ±5 minutes were considered acceptable.
Corneal thickness and corneal opacity were measured at all time points. Fluorescein retention was measured on two occasions, at base line (t=0) and approximately 30 minutes after the post-treatment rinse. Haag-Streit Bern 900 slit-lamp microscope was used for the measurements. - Irritation parameter:

- Identification of pH
The pH of the test item was determined. The pH was found to be 5.0, so the test item is permitted for use in animal studies.
Pre-study examination
Three male animals in acceptable health condition were selected for the test. Care was taken to select only those animals that had a normal eye condition and any with ocular lesions were rejected.
Chronology of animal use
Initially only one rabbit was treated with test item. As there was no severe effect was observed then one further rabbit was treated after 48 hour observation of the first rabbit. Then as the results in the second rabbit were not severe, a third rabbit was treated as for determined the classification.
Analgesic and anaesthetic treatment
Sixty minutes (60 ±10 min) prior to test substance application, a systemic opiate analgesic was administered subcutaneous injection (SC) under direct Veterinary supervision.
Five minutes (5 ±1.5 min) prior to test substance application, a topical ocular anaesthetic was applied to each eye (including the control eye to ensure direct comparison of any ocular observations).
Eight hours (8 to 9 hr) after test substance application, a systemic opiate analgesic and a nonsteroidal anti-inflammatory drug (NSAID) were administered subcutaneous injection (SC) under direct Veterinary supervision. The systemic opiate analgesic was injected ~12 hours, until the ocular lesions were resolved and no clinical signs of pain or distress were present.
Systemic opiate analgesic: Buprenorphine 0.01 mg/kg.
Topical ocular anaesthetic: Humacain (oxybuprocaine) one-two drops per eye.
Nonsteroidal anti-inflammatory drug: Meloxicam 0.5 mg/kg.
ADMINISTRATION OF THE TEST ITEM
Dosage
A single dose of 0.1 g of test item SH-0850 was administered to the animal.
Application of the Test Item
The test substance was placed in the conjunctival sac of the left eye of each animal after gently pulling the lower lid away from the eyeball. The lids were then gently held together for at least one second in order to prevent loss of the material.
The untreated contralateral eye was served as the control.
Duration of Exposure
The treated eye was rinsed with physiological saline solution at the first observation time point in all animals at one hour after the application of test item as the irritation scores were greater than 1 and residual test item was noted on the eye.

The eyes were examined at 1, 24, 48 and 72 hours after treatment. The duration of the observation period was sufficient to identify reversibility or irreversibility of changes. Any clinical signs of toxicity or signs of ill-health during the study were recorded. At the end of the observation period, the animal was sacrificed by intramuscular injections of CP-Ketamin 10% and CP-Xylazin 2% followed by i.v. Pentobarbital sodium. Death was verified by checking pupil and corneal reflex and the absence of respiration.
All rabbits were examined for distress at least twice daily, with observations at least 6 hours apart. Clinical observations or signs of ill-health were recorded.
Scoring and Assessment of Local Reaction
The eye irritation scores were evaluated according to the scoring system by Draize (1977) and OECD 405 (02 October 2012).

Based on this in vitro eye irritation assay in the isolated chicken eyes test with SH-0850, the test item is not classified as a severe irritant and not classified as non-irritant. No conclusion of in vivo significance can be made from the adherence of the test item to the cornea, since in vivo eye lids may clear the surface, but abrasion may occur. It is concluded that an in vivo study is required for classification.

Additional information
Skin irritation/corrosion - in vivo
An acute skin irritation study was performed with SH-0850 in New Zealand White rabbits.
A weight of 0.5 g for solid test item was applied to the skin of the experimental animals. The test item was applied as a single dose. Sufficient water to damp the material was used to ensure good contact with the skin and an adhesive clear plastic patch was applied. The trunk was wrapped in clear plastic with medical tubing used to hold the patch in place. The untreated skin of each animal served as control.
After 4 hours, the remaining test item was removed with water at body temperature.
To assess skin irritation, animals were examined at 1, 24, 48 and 72 hours after the patch removal. Additional general examinations were performed daily.
There was no mortality or systemic clinical changes related to SH-0850 administration. There was no effect of treatment on body weight.
At observation one, 24, 48 and 72 hours after patch removal, there were no observed clinical signs noted on the skin of the treated animals. As no clinical signs were observed the study was terminated after the 72 hours observation.
The animals’ individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for erythema and oedema were 0.00, 0.00 and 0.00 respectively.
SH-0850 is a "non-irritant".
Eye irritation - in vitro
An in vitro eye irritation study of the test item SH-0850 was performed in isolated chicken’s eyes.
After the zero reference measurements, the eye was held in horizontal position and 30 mg of SH-0850 was applied onto the centre of the cornea such that the entire surface of the cornea was covered. After 10 seconds, the surface was rinsed with saline. The positive control eyes were treated with 30 mg Imidazole. The negative control eye was treated with 30 μL of Saline (Salsol solution, NaCl 0.9% w/v).
Based on the in vitro eye irritation in the isolated chicken eyes test with SH-0850, the test item is not classified as a severe irritant and not classified as non-irritant. No conclusion of in vivo significance can be made from the adherence of the test item to the cornea, since in vivo eye lids may clear the surface, but abrasion may occur. It is concluded that an in vivo study is required for classification.

There was no clinical sign of systemic toxicity observed in the animals during the study and no mortality occurred.
During the study, the control eye of each animal was symptom-free.
The body weights of the animal were considered to be within the normal range of variability.
The animal individual mean scores (considering readings at 24, 48 and 72 hours after the treatment) were as follows:
