SDTM Example. Cigarette Design Parameters

Tobacco domains

DI = TO for Tobacco Product Identifier

SPDEVID = SPTOBID for Sponsor Tobacco Device Identifier

DO/DU = Tobacco Design Parameters (DP)

LB = Tobacco Product Testing (TT)

This is an example for the required tobacco product categorization, property description, and design parameter information in an FDA marketing application for one type of tobacco product Cigarette. There are many more and various types of tobacco products, and their parameters can be found in the in the FDA final rule and guidance documents for tobacco products Premarket Authorization (PMTA) and Substantial Equivalence (SE) Pathways. The applicant submitting for SE and PMTAs should provide test data to include test protocols, quantitative acceptance criteria, data sets, and summary of results as applicable for these parameters.

Tobacco Products (TO) is a study reference dataset that provides a mechanism for uniquely identifying a tobacco product. It is similar to Device Identifiers (DI) in function. The primary purpose of this dataset is to provide a list of the products used in an application or study and to provide identifying information for each product, such as product category type, manufacturer, model (product) name, etc., as applicable. All identifying information is grouped by the Sponsor Tobacco Product Identifier (SPTOBID) (similar to Sponsor Device Identifier (SPDEVID) a consistent variable, that is available for use in other domains where data pertaining to the product may be found.

Steve H's suggestion of combining our previous product identifiers and product descriptors into a single dataset. This is a more traditional findings dataset structure. Advantages: it doesn't break any rules. SPTOBID is the Sponsor-defined Tobacco Product Identifier, and serves as the "subject" of all records since these are not (human) subject-level data.

Rows 1-4:	Show the records for a tobacco product identifiers that were previously represented in a separate DI dataset
Rows 5-10:	Show the product descriptors which we would have originally put in a DO-like dataset.

The Tobacco Product Design Parameters (DP) represents the manufacturing parameter specifications of the tobacco product as used. The example below shows the target, minimum, and maximum values associated with each of 19 separate design parameters. These parameters are defined as manufacturing guidelines, not determined experimentally.
