Availability of the ICCVAM Test Method Evaluation Report and Final Background Review Document.
NICEATM announces availability of the ICCVAM Test Method Evaluation Report: Validation Status of Five In Vitro Test Methods Proposed for Assessing Potential Pyrogenicity of Pharmaceuticals and Other Products (NIH Publication 08-6392). The test method evaluation report (TMER) describes five in vitro pyrogen test methods that can be used for detecting Gram-negative endotoxin in human parenteral pharmaceuticals. The report includes ICCVAM's (a) Recommendations on uses and limitations for each test method, (b) recommendations for standardized protocols, (c) recommendations for future studies, and (d) recommendations for the development of performance standards.
ICCVAM concludes that none of these test methods can be considered as a complete replacement for the rabbit pyrogen test (RPT) for all testing situations for the detection of Gram-negative endotoxin. However, ICCVAM recommends that they can be considered for use on a case-by-case basis to detect Gram-negative endotoxin in human parenteral drugs, subject to product-specific validation to demonstrate equivalence to the RPT, in accordance with applicable U.S. Food and Drug Administration regulations. When used in this manner, these methods can reduce the number of animals needed for pyrogenicity testing. The report also recommends that these Start Printed Page 71004and other in vitro alternative test methods be considered prior to in vivo pyrogenicity testing, where determined appropriate for a specific testing situation.
NICEATM also announces availability of the final ICCVAM Background Review Document: Validation Status of Five In Vitro Test Methods Proposed for Assessing Potential Pyrogenicity of Pharmaceuticals and Other Products (NIH Publication 08-6391). The final background review document (BRD) provides the data and analyses used to assess the current validation status of these five in vitro test methods.
The ICCVAM TMER and supporting BRDs have been forwarded to U.S. Federal agencies for regulatory and other acceptance consideration, where applicable. Responses received will be posted on the NICEATM-ICCVAM Web site.
Electronic copies of the ICCVAM TMER and final BRD are available from the NICEATM-ICCVAM Web site at http://iccvam.niehs.nih.gov or by contacting NICEATM (see FOR FURTHER INFORMATION CONTACT).Start Further Info

In 2005, the European Centre for the Validation of Alternative Methods (ECVAM), a unit of the Institute for Health and Consumer Protection at the European Commission's Joint Research Centre, submitted BRDs for five in vitro pyrogen test methods proposed as replacements for the RPT to ICCVAM for formal evaluation of their scientific validity for regulatory testing purposes. ICCVAM unanimously agreed that the five submitted in vitro pyrogen test methods should have high priority for evaluation. On December 16, 2005, NICEATM published a Federal Register notice (Vol. 70, No. 241, pages 74833-74834), requesting public comments on the appropriateness and relative priority of convening an independent peer review panel (Panel) to evaluate the validation status of the five in vitro pyrogen test methods, the nomination of scientists to serve on the Panel, and the submission of data from in vivo and in vitro pyrogenicity testing. Based on the ECVAM BRDs as well as data and information submitted in response to the aforementioned Federal Register notice, NICEATM subsequently compiled a comprehensive draft BRD on the five in vitro pyrogen test methods and released it for public comment on December 12, 2006 (Vol. 71, No. 238, pages 74533-74534).
On February 6, 2007, NICEATM and ICCVAM convened a Panel to review the ICCVAM draft BRD for errors and omissions and to evaluate the validation status of the five in vitro pyrogen test methods. The Panel also reviewed the extent that the information contained in the ICCVAM draft BRD supported the ICCVAM draft test method recommendations for proposed test method uses, standardized protocols, test method performance standards, and additional studies. The Panel considered public comments made at the Panel meeting, as well as public comments submitted in advance of the meeting, before concluding their deliberations. NICEATM made the Panel's report available in May 2007 (Vol. 72, No. 89, pages 26395-26396). The ICCVAM draft BRD and draft recommendations, the Panel's report, and all public comments were made available to the Scientific Advisory Committee on Alternative Toxicological Methods (SACATM) for review and comment at their meeting on June 12, 2007 (Vol. 72, No. 83, pages 23831-23832).
ICCVAM considered the Panel's report, all public comments, and the comments of SACATM in finalizing its recommendations on the use of these five in vitro test methods proposed for assessing potential pyrogenicity of pharmaceuticals and other products. The ICCVAM TMER includes the ICCVAM recommendations on uses and limitations for each test method, standardized protocols, future studies, and the development of performance standards, as well as the Panel's report and Federal Register notices. The final BRD, which provides the supporting documentation for this report, is available as a separate document. ICCVAM forwarded the ICCVAM TMER and the supporting final BRD to U.S. Federal agencies for consideration, in accordance with the ICCVAM Authorization Act of 2000 (42 U.S.C. 285 l-3). Agency responses to the ICCVAM test method recommendations will be made available on the NICEATM-ICCVAM Web site as they are received.
Background Information on ICCVAM, NICEATM, and SACATM
ICCVAM is an interagency committee composed of representatives from 15 Federal regulatory and research agencies that use, generate, or disseminate 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 established ICCVAM as a permanent interagency committee of the NIEHS under NICEATM. NICEATM administers ICCVAM and provides scientific and operational support for ICCVAM-related activities. NICEATM and ICCVAM work collaboratively to evaluate new and improved test methods applicable to the needs of U.S. Federal agencies. Additional information about ICCVAM and NICEATM can be found at http://www.iccvam.niehs.nih.gov.
SACATM was established January 9, 2002 (Vol. 67, No. 49, page 11358), and is composed of scientists from the public and private sectors. SACATM provides advice to the Director of the NIEHS, to ICCVAM, and to NICEATM regarding the statutorily mandated duties of ICCVAM and activities of NICEATM. Additional information about SACATM, including the charter, roster, and records of past meetings, can be found at http://ntp.niehs.nih.gov/go/167.Start Signature
