Draft Guidance on Developing Robust Summaries

(October 22, 1999)

The guidance in the following tables are presented exactly as they appear in the official OECD document entitled "Guidance for Developing Robust Summaries for SIDS Dossiers" (Document number ENV/JM/EXCH(99)13, dated 10/8/99). EPA provides the following narrative as an introduction to the OECD tables.

Definition/Background

The purpose of the U.S. HPV Chemical Challenge Program is to make hazard data (either existing or newly acquired information) available to the public for all U.S. high production volume chemicals. Most HPV Challenge sponsors will have at least some existing data in the form of full study reports for some or all of the endpoints in the Screening Information Data Set (SIDS). Sponsors need to determine whether available information already adequately describes a given endpoint. EPA guidance for determining data adequacy has already been provided. Once one or more studies have been identified as adequate, then they need to be made public in the Challenge Program. From a practical standpoint, it is not reasonable to attempt to create an electronic version of full study reports (especially old reports that may date to the 1960s or earlier). Instead, electronic summaries of full study reports will be prepared that contain the appropriate technical information for that particular endpoint.

The purpose of this document is to present guidance on what technical information, on an endpoint-by-endpoint basis, is necessary to adequately describe an experiment or study. The term "robust summary" is used to describe this technical content. Robust study summaries are intended to provide sufficient information to allow a technically qualified person to make an independent assessment of a given study report without having to go back to the full study report, and to also allow evaluation of the proposed test plan. A robust study summary therefore reflects the objectives, methods, results, and conclusions of the full study report, which can either be an experiment or in some cases an estimation or prediction method.

Which Studies Require Robust Summaries?

A complete robust study summary should be prepared for at least one key or critical study for each SIDS endpoint that has been considered adequate according to EPA guidance. Robust summaries may also be prepared for other adequate studies that are considered supportive of the key study. When you don't have an adequate study, but some information is available, it is suggested that robust summaries be prepared for each study. In addition, a single "best" study would contain a weight-of-the-evidence analysis in its remarks section (see below) which refers to, and ties together, the other studies.

Origin of the Guidance

The templates for robust study summaries presented in the following pages were based on: (1) current guidance in the Organization of Economic Cooperation and Development (OECD) SIDS Manual; (2) work carried out by the US EPA in the context of the US HPV Challenge Program; (3) work carried out by the Chemical Manufacturers Association (CMA) and the Business and Industry Association Council (BIAC) relating to both the U.S. Challenge Program and the OECD SIDS program; and (4) work relating to the International Uniform Chemical Information Database (IUCLID) carried out by the European Commission. The draft guidance contained in this document is currently being considered by an international group of scientists associated with the OECD for its usefulness in the OECD SIDS program. Therefore, while there might be some changes made over the next few months, the EPA believes it is useful to place these templates on our website as guidance for early submitters and those who have been following the discussion of this issue over the past year. EPA intends to combine this document with the data adequacy document because the guidance presented herein simply captures the information gleaned during the data adequacy determination.

Robust Study Summary Templates

A series of templates for the different SIDS endpoints have been developed. They have been structured to allow for computerised data entry by describing the items in each robust study summary as "data fields" with allowance for free text. The proposed robust study summary templates have seven sections on: Test Substance, Methods, Results, Conclusion, Data Quality, References, and Other.

In the following pages, templates for the listed SIDS endpoints are provided:

Physical/Chemical Elements

1) Melting point
2) Boiling point
3) Vapor pressure
4) Partition coefficient
5) Water solubility
Environmental Fate and Pathways Elements
6) Photodegradation
7) Stability in water
8) Transport between Environmental Compartments (Fugacity)
9) Biodegradation
Ecotoxicity Elements
10) Acute toxicity to fish
11) Toxicity to aquatic plants
12) Acute toxicity to aquatic invertebrates
Health Elements
13) Acute toxicity
14) Genetic toxicity in vivo(chromosomal aberrations)
15) Genetic toxicity in vitro (gene mutations)
16) Repeat dose toxicity
17) Reproductive Toxicity
18) Developmental Toxicity/Teratogenicity
No templates are currently available for non-SIDS endpoints. Information on these is nevertheless encouraged to be included where available and relevant to the assessment.

Explanation of the Templates

Each template identifies the information items that should be included in a robust study summary for that SIDS endpoint. As many items of information as possible should be provided since robust study summaries concern the key study(s) on which the assessment of each SIDS endpoint is based. It is generally expected that the most adequate, reliable, and relevant study for each SIDS endpoint will be clearly identified and reported to the fullest level of the template. In cases where the study is considered inadequate, this should be clearly marked together with the reasons.

Each template is composed of seven sections, each section each of which has two different types of fields: controlled vocabulary and free text. The controlled vocabulary fields are identified in the templates by individual bullets, which are required to be filled out, while the free text field under each section entitled "Remarks"   allows the input of optional information.

Often, the "Remarks" section can be used as a means to further explain the contents of a particular section, much as is done in the "Discussion" portion of a publication in academic journals. For example, under the "Results" section, unexpected results could be further explained in the "Remarks" field (i.e., results seen were due to the complex nature of the test substance, deviations in protocol, etc.).

Test substance

This refers to the identity of the HPV chemical. If the chemical used in the specific test was different from the specific HPV chemical in identity (purity, additives, different solvent carrier, etc), then those differences need to be noted in the Test Substance Remarks field together with the chemical name, CAS number, purity of the materials, additives, and chemical structure as appropriate. If the chemical(s) is listed in the IUCLID system, it would also be useful to have an IUCLID identification number.

Methods

This section refers to the methodologies used to conduct the study. If the study was done according to OECD Test Guidelines, or other widely recognized guidelines, then it does not need to be fully described. For example, only the name of the guideline (e.g., OECD 421) needs to be reported. If there have been deviations from the Test Guideline, then those deviations that will significantly impact either the study reliability or the interpretation of the data need to be individually listed. On the other hand, if a study is based on a guideline that is not widely recognized, more items under the "Remarks" field may need to be included to justify use of the guideline.

There may also be situations in which a single study addresses several endpoints, such as with a study that follows the OECD combined repeat dose/reproduction/developmental Test Guideline 421. In this example, if this single study was to be the key one for each of these endpoints, then three separate robust study summaries would be prepared for each endpoint - all pointing to the same study.

Results

This section has standard items to fill in under discrete bullets, and also a "Remarks" field with additional items that may be needed to adequately assess data for reliability and use. At a minimum, qualitative descriptions of elements where dose-related observations were seen should be described.

Conclusions

This section has a "Remarks" field only, so that the conclusions of the study can be noted if given, together with any comments by the person preparing the robust study summary.

Data Quality

This section can be used to denote the adequacy of data, at the discretion of the person preparing the robust study summary

References

This free text field allows the person preparing the robust study summary to provide the full citation for the critical study on which the robust study summary is based.

Other

This section includes a data field for revisions, a number useful for sorting, and a free text field for general remarks.
