- Details on test animals or test system and environmental conditions:
- The age at treatment of the Rabbit was 10 weeks for male and 13-14 weeks for females. The Rabbit was placed under laboratory conditions after healt examinations. Only animals without any visual signs of illness were used for the study.
Air-conditioned with target ranges for room temperature 17-23 °C, relative humidity 30-70% and approximately 10-15 air changes per hour. Room temperature and humidity were monitored continuously and values outside of these ranges may have occasionally occurred, usually following room cleaning. These transient variations are considered not to have any influence on the study and, therefore, these data are not reported but are retained at RCC. The animals were provided with an automatically controlled light cycle of
12 hours light and 12 hours dark. Music was played during the daytime light period.
Individually in stainless steel cages equipped with feed hoppers and drinking water bowls. Wood blocks and haysticks 4646 were provided for gnawing. Pelleted standard Provimi Kliba 3418 rabbit maintenance diet ad libitum. Community tap water, ad libitum. - Type of coverage:

- Duration of treatment / exposure:
- 4 hours
- Observation period:
- 1, 24, 48 and 72 hours alter the removal of the dressing, gauze patch and test item.
- Number of animals:
- 3
- Details on study design:
- Four days before treatment, one flank was clipped with an electric clipper, exposing an area of approximately 100 cm2 (10 cm x 10 cm). The skin of the animals was examined one day before treatment, and regrown fur of all animals was again clipped.
Animals with overt signs of skin injury or marked irritation which may have interfered with the interpretation of the results were not used in the test.
On the day of treatment, 0.5 mL of FEXO-03 was placed on a surgical gauze patch (ca. 4 cm x 4 cm). This gauze patch was applied to the intact skin of the clipped area. The
patch was covered with a semi-occlusive dressing. The dressing was wrapped around the abdomen and anchored with tape.
The duration of treatment was 4 hours. Then the dressing was removed and the skin was flushed with lukewarm tap water to clean the application sile so that any reactions
(erythema) were clearly visible at that time.
The observation has regarded the viability/mortality, the clinical signs and the body weights.
The skin reaction was assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEC, July 31, 1992 approximately 1, 24, 48 and 72 hours alter the removal of the dressing, gauze patch and test item. - Irritation parameter:

Air-conditioned with target ranges for room temperature 17-23 °C, relative humidity 30-70% and approximately 10-15 air changes per hour. Room temperature and humidity
were monitored continuously and values outside of these ranges may have occasionally occurred, usually following room cleaning. These transient variations are considered not

lndividually in stainless steel cages equipped with feed hoppers and drinking water bowls. Wood blocks and haysticks 4646 were provided for gnawing.
Pelleted standard Provimi Kliba 3418 rabbit maintenance diet ad libitum (batch no. 52/03). Results of analysis for contaminants are archived at RCC Ltd.
Community tap water ad libitum. Results of bacteriological, chemical and contaminant analyses are archived at RCC Ltd. - Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The right eye remained untreated and served as the reference control.
- Amount / concentration applied:
- 0.1 ml (per animal) of FEXO-03 was measured with a syringe and applied undiluted as it was delivered by the sponsor.
- Duration of treatment / exposure:
- On the day of treatment
- Observation period (in vivo):
- 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after instillation.
- Number of animals or in vitro replicates:
- 3 (animals of both sexes were used)
- Details on study design:
- 0.1 ml (per animal) of FEXO-03 was measured with a syringe and applied undiluted as it was delivered by the sponsor.
The pH of the test item was measured for a previous study (RCC Study number 851037, skin irritation with FEXO-03 in rabbits) and was found to be 6.
According to Directive 92/69 EEC, B.5. and OECD Guidelines 405, a test item needs not to be tested if the pH-value is less than 2 or greater than 11.5, owing to its predictable corrosive properties.
The eyes of the animals were examined one day prior to test item administration. Animals with overt signs of ocular injury or irritation which may have interfered with the
interpretation of the results were not used in the test.
On the day ol treatment, 0.1 ml of FEXO-03 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 about one second to prevent loss ol test item. The right eye remained untreated and served as the reference control. The treated eyes were not rinsed alter instillation.
As the first animal screamed just after the application only this single animal (one male) was treated according to the study plan schedule. As neither a corrosive effect nor a severe irritant effect was observed alter the 1- and 24-hour examinations, the test was completed using the two remaining animals (two females).
OBSERVATIONS
Viability/Mortality - Daily from acclimatization of the animals to the termination of test.
Clinical signs - Daily from acclimatization of the animals to the termination of test.
Body weights - At start of acclimatization, on the day of application and at termination of observation.
The ocular reaction was assessed according to the numerical scoring system listed in the EEC Commission Directive 92/69/EEC, July 31, 1992 at approximately 1, 24, 48 and
72 hours, as well as 7, 10 and 14 days alter instillation.
