Those persons submitting data on chemicals tested for ocular irritancy in rabbits are referred to the ICCVAM/NICEATM Web site (http://iccvam.niehs.nih.gov/methods/eyeirrit.htm) for an example of the type of experimental animal study information and data requested in this notice.

In Vitro Ocular Irritancy Chemical Tests: BCOP, HETCAM, ICE, and IRE

NICEATM is especially interested in data from four in vitro test methods used to identify severe (irreversible) ocular irritation/ corrosion: BCOP, HETCAM, ICE, and IRE. Because test methods for identifying severe eye irritants/corrosives are of high priority, NICEATM especially requests data on chemicals identified by these four methods as severe irritants, although data on mildly irritating and nonirritating substances are also welcome.

Other In Vitro Ocular Irritancy Methods

NICEATM also requests the submission of data and information for standardized in vitro ocular irritancy methods, other than the four identified above, and methods that might be used to identify non irritating and mild to moderate irritants. Detailed test method protocols and other related information for these potential test methods should be submitted along with the data.

In Vivo Test Methods for Ocular Irritancy

NICEATM requests the submission of high quality in vivo data that might be used to identify appropriate reference chemicals for future validation studies of in vitro ocular irritancy test methods. Data are sought from studies conducted to comply with federal or other national/ international testing requirements, but may not be publicly available because: (1) The data were submitted to regulatory authorities, but are proprietary and cannot be released to the public by regulatory authorities, or (2) there is no requirement to submit the data to regulatory authorities. In addition to data from studies in animals, NICEATM also welcomes the submission of data from human studies including any human postmarketing or occupational exposure/ surveillance data that might be available.
Procedures for Reducing or Eliminating Pain and Suffering during In Vivo Ocular Irritancy Testing

NICEATM requests the submission of information and data from in vivo methods, procedures, and/or strategies that may reduce or eliminate the pain and suffering associated with current in vivo eye irritation methods, such as those using topical or systemic analgesics. Background Information

In August 2003, the Scientific Advisory Committee on Alternative Toxicological Methods (SACATM) unanimously recommended that NICEATM focus efforts on test methods for ocular irritancy and possibly hold a workshop and/or develop a background document on available methods. In October 2003, the U.S. Environmental Protection Agency nominated the following activities to ICCVAM: (1) Evaluate the validation status of the four in vitro ocular toxicity test methods (BCOP, IRE, ICE, and HETCAM), (2) identify and develop in vivo ocular toxicity reference data to support the validation of in vitro test methods, (3) explore ways of alleviating pain and suffering from current in vivo ocular toxicity testing, and (4) review the state of the science and the availability of in vitro test methods for assessing mild or moderate ocular irritants. ICCVAM endorsed the review of these methods as a high priority and recommended that NICEATM develop Background Review Documents for BCOP, IRE, ICE, and HETCAM. NICEATM convened an independent expert panel on January 1112, 2005, to review the validation status of these four methods and develop conclusions and recommendations on standardized protocols and reference chemicals for future testing and validation studies. Availability of the expert panel's report will be announced in a future Federal Register notice. Background Information on ICCVAM and NICEATM

ICCVAM is an interagency committee composed of representatives from fifteen federal regulatory and research agencies that use or generate toxicological information. ICCVAM conducts technical evaluations of new, revised, and alternative methods with regulatory applicability, and promotes the scientific validation and regulatory acceptance of toxicological test methods that more accurately assess the safety and hazards of chemicals and products and that refine, reduce, and replace animal use. The ICCVAM Authorization Act of 2000 (P.L. 106545, available at http://iccvam.niehs.nih.gov/about/PL106545.htm) establishes ICCVAM as a permanent interagency committee of the NIEHS under the NICEATM. NICEATM administers and provides scientific support for the ICCVAM. NICEATM and ICCVAM work collaboratively to evaluate new and improved test methods applicable to the needs of federal agencies.

SUMMARY:

National Institute of Environmental Health Sciences, National Institutes of Health—; Ocular toxicity test methods nomination and chemicals and products tested for ocular irritancy using in vitro or in vivo test methods,

DOCUMENT BODY 2:

Summary

The Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) and NICEATM are collaborating with the European Center for the Validation of Alternative Methods (ECVAM) to evaluate the validation status of in vitro methods for assessing ocular irritation/corrosion. Data was previously requested (Federal Register, Vol. 69, No. 57, pp. 1385913861, March 24, 2004, available at http://iccvam.niehs.nih. gov/) and used to prepare draft Background Review
Documents (BRD) for four methods [(1) The Bovine Corneal Opacity and Permeability (BCOP) test; (2) the Isolated Rabbit Eye (IRE) test or the Rabbit Enucleated Eye Test (REET); (3) the Isolated Chicken Eye (ICE) test or the Chicken Enucleated Eye Test (CEET); and (4) the Hen's Egg TestChorion Allantoic Membrane (HETCAM)], and to compile a database of in vivo data. ICCVAM and NICEATM are now finalizing these BRDs and want to ensure the inclusion of all available data. NICEATM is therefore issuing this second request for data generated using standardized in vitro and in vivo test methods used to identify severe, moderate, mild, or nonirritating substances. Test methods for identifying severe (irreversible) ocular irritation/corrosion for which data are sought include, but are not limited to: (1) The BCOP test; (2) the IRE test; (3) the ICE test; and (4) the HETCAM. In addition, high quality data from standardized ocular irritancy test methods using rabbits (e.g., EPA 1998; UN 2003) and in vivo data generated from procedures/protocols that might alleviate or reduce pain and suffering (e.g., topical and systemic analgesic) in test animals are requested. These data will be used to evaluate the validation status of existing in vitro test methods for ocular irritancy/corrosion and to develop a list of substances with high quality in vivo data that can be considered as reference chemicals for future validation studies. Data from other in vitro methods used to assess reversible ocular irritation effects or nonirritation are also requested.
Submission of Chemical and Protocol Information and Test Data

Data and other information submitted in response to this notice should be sent to NICEATM [Dr. William S. Stokes, Director, NICEATM, NIEHS, 79 T. W. Alexander Drive, P.O. Box 12233, MD EC17, Research Triangle Park, NC 27709, (phone) 9195412384, (fax) 9195410947, iccvam@niehs.nih.gov] and received by March 30, 2005. Data and other information received by this date will be compiled and added to the database maintained by NICEATM and utilized where appropriate for the final BRDs on the four methods listed above. Data received after this date will also be considered and used where applicable for future evaluation activities. All information submitted in response to this notice will be made publicly available upon request to NICEATM.

When submitting data or information on protocols, please reference this Federal Register notice and provide appropriate contact information (name, affiliation, mailing address, phone, fax, email, and sponsoring organization, as applicable). NICEATM prefers data to be submitted as copies of pages from study notebooks and/or study reports, if available. Each submission for a chemical should preferably include the following information, as appropriate:

Those persons submitting data on chemicals tested for ocular irritancy in rabbits are referred to the ICCVAM/NICEATM Web site (http://iccvam.niehs.nih.gov/methods/eyeirrit.htm) for an example of the type of experimental animal study information and data requested in this notice.
