- Albino rabbit, New Zealand White, (SPF-Quality). Recognized by international guidelines as the recommended test system (e.g. EC, OECD) Source: Charles River France, L’ArbresleCedex, France
3 males. At start of dosing, the animals were between 12 and 24 weeks old and body weights were at least 1.5 kg.
Conditions
Environmental controls for the animal room were set to maintain 18 to 24°C, a relative humidity of 40 to 70%, at least 10 air changes/hour, and a 12-hour light/12-hour dark cycle. Any variations to these conditions were maintained in the raw data and had no effect on the outcome of the study.
Accommodation
Animals were individually housed in labeled cages with perforated floors (Ebeco, Germany, dimensions 67 x 62 x 55 cm) and shelters (Ebeco, Germany, dimensions 40 x 32 x 23 cm). Acclimatization period was at least 5 days before start of treatment under laboratory conditions.
Diet
Pelleted diet for rabbits (Global Diet 2030 from Harlan Teklad®, Mucedola, Milanese, Italy) approximately 100 grams per day. Hay (TecniLab-BMI BV, Someren, The Netherlands) and wooden
sticks (Swedish aspen wood, Bioservices, Uden, The Netherlands) were available during the study period.
Water
Free access to tap water.
Diet, water, bedding and cage enrichment evaluation for contaminants and/or nutrients was performed according to facility standard procedures. There were no findings that could interfere with the study
Test system

- unchanged (no vehicle)
- Amount / concentration applied:
- 20.6mg (range 20.5 - 20.8mg)
- Duration of treatment / exposure:
- 1 hour
- Observation period (in vivo):
- 1,24,48,72 hours and 7 days after instillation of the test substance
- Number of animals or in vitro replicates:

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- PF-06410251 is not an eye irritant.
- Executive summary:
Acute eye irritation/corrosion study withPF-06410251 in the rabbit. The study was carried out based on the guidelines described in: OECD No.405 (2012) "Acute Eye Irritation / Corrosion" EC, No 440/2008, B5: "Acute Toxicity: Eye Irritation/Corrosion" EPA, OPPTS 870.2400 (1998): "Acute Eye Irritation" FAMIC Guidelines (2011), including the most recent revisions. Single samples of approximately 21 mg ofPF-06410251 (a volume of approximately 0.1 mL) were instilled into one eye of each of three rabbits. Observations were made 1, 24, 48 and 72 hours and 7 days after instillation. Instillation of the test substance resulted in effects on the cornea, iris and conjunctivae. The corneal injury in two animals consisted of epithelial damage and resolved within 24 hours in both animals. Iridial irritation was observed in all animals and resolved within 24 hours. The irritation of the conjunctivae consisted of redness, chemosis and discharge and completely resolved within 7 days in all animals. Remnants of the test substance were present in the eye of all animals on Day 1. Based on these results, PF-06410251 does not have to be classified and has no obligatory labelling requirement for eye irritation according to the: - Globally Harmonized System of Classification and Labelling of Chemicals (GHS) of the United Nations (2011) (including all amendments), - Regulation (EC) No 1272/2008 on classification, labelling and packaging of substances and mixtures (including all amendments).
