- Details on test animals or test system and environmental conditions:
- Rabbits Chbb:HM (SPF) from Dr. K. Thomae GmbH, Biberach (FRG) were used. Animals were utilized only if they were judged healthy on the basis of general
observations and body weight (performed predose).
Animals were assigned to the study using computer-generated random numbers.
Animal identification was by an individual number written with a waterproof marker on the ear.
The animals were acclimatized to laboratory conditions for 7 days. The initial age (at dosing) was 148 to 169 days. The initial weight range (at dosing) was 2309 to
2346 g.
Husbandry
The animals were housed individually in stainless steel cages in an air-conditioned room. The temperature was 20 ± 3 °c, and the relative humidity 30 to 70 %.
Artificial light was provided from 6 a.m. to 6 p.m.
Pelleted standard diet NAFAG No. 814 was freely available (NAFAG, 9202 Gossau, Switzerland). The diet is analyzed for composition and contaminants by
the manufacturer and analytical results are archived by the Animal Supply Office CIBA-GEIGY (batches are given in the raw data).
Tap water was freely available. The water is analyzed periodically by Industrielle Werke Basel (Basel City water supply plant) for compliance with Swiss drinking
water specifications. - Type of coverage:

Eye irritation
Link to relevant study records
- Endpoint:
- eye irritation: in vitro / ex vivo
- Data waiving:
- study scientifically not necessary / other information available
- Justification for data waiving:
- an in vitro eye irritation study does not need to be conducted because adequate data from an in vivo eye irritation study are available
- Justification for type of information:
- The in vivo test is performed according to Novartis internal Tiered Testing Strategy as a regular set of tests for all substances during the development of the project. (TRD Development Manual Chapter C.26 requirements.)
The Novartis Pharma Data Set (NPDS) has been put in place many years before the REACh regulation was released and we have, since then, systematically acquired data for all substances (RM, IM, DS, reagents, etc.) on behalf of TRD and PCS, for internal and external classification purposes. - Endpoint:

- Details on test animals or tissues and environmental conditions:
- Rabbits Chbb:HM (SPF) from Dr. K. Thomae GmbH, Biberach (FRO) were used. Animals were utilized only if they were judged healthy on the basis of general
observations and body weight (performed predose).
Animals were assigned to the study using computer-generated random numbers.
Animal identification was by an individual number written with a waterproof marker on the ear.
The animals were acclimatized to laboratory conditions for 8 days. The initial age (at dosing) was 179 to 193 days. The initial weight range (at dosing) was 2145 to
2252 g.
Husbandry
The animals were housed individually in stainless steel cages in an air-conditioned room. The temperature was 20 ± 3 °c, and the relative humidity 30 to 70 %.
Artificial light was provided from 6 a.m. to 6 p.m.
Pelleted standard diet NAFAG No. 814 was freely available (NAFAG, 9202 Gossau, Switzerland). The diet is analyzed for composition and contaminants by the manufacturer and analytical results are archived by the Animal Supply Office CIBA-GEIGY (batches are given in the raw data).

water specifications. - Vehicle:
- unchanged (no vehicle)
- Controls:
- other: not required, the untreated eye of each animal served as control
- Amount / concentration applied:
- Application volume: approx. 0.1 g / animal
0.07 g was the maximal amount which could be put into the conjunctiva! sac
The Test Artice! was administered into the conjunctiva! sac of one eye. The contralateral eye was used as control. - Duration of treatment / exposure:
- single application
- Observation period (in vivo):
- 72 h
reading time points: 1, 24, 48 and 72 h - Number of animals or in vitro replicates:
- 3
- Details on study design:
- Three animals of a pool were selected based on a primary eye examination (24 hrs. before dosing).
0.1 g of the test article was prepared for the application into the conjunctiva! sac of the first animal. 0.07 g was the maximal amount which could be put into the
conjunctiva! sac. After the first assessment of eye reactions in the first animal, the same amount (0.07 g) of compound was then applied to two additional animals.
This stepwize procedure was used to omitt unexpected severe eye reactions in a whole group of 3 animals.
The lids were gently hold together for a second to prevent loss of material.
The test article was administered once.
The administration was performed between 10:00 a.m. and 12:00 a.m .. - Irritation parameter:
