title	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.

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.

The following tables illustrate the controlled terminology for the the --TESTCD and --TEST values that should be submitted for in datasets according to the examples above. for each tobacco product category. (We'll add more language as necessary to make this clearer)

Info
Sponsors should always verify controlled terminology using the published CDISC controlled terminology for the associated codelists below

example illustrates the representation of a cigarette product's identifiers and descriptors using the TO domain. Note that this example uses TOSCAT (Subcategory of Tobacco Prod ID Element, a permissible variable) to emphasize and differentiate the 2 distinct types of parameters represented in TO: tobacco product identifiers and tobacco product descriptors.

The manufacturing parameter specifications of the cigarette tobacco product as intended for use are represented in the PD domain The following example shows the target, minimum, and maximum values associated with each of 23 separate design parameters. These parameters are defined manufacturing specifications, not characteristics that are determined experimentally.

Note the use of the variable IGDCMPID (Ingredient or Component Identifier) in rows 5-6. This tobacco product had 2 tobacco ingredients with 2 different tobacco cut sizes. IGDCMPID identifies to which tobacco ingredient the cut size applies. IGDCMPID originates in the IT (Tobacco Ingredients) and IN (Non-Tobacco Ingredients) domains. See Section 3.1.3.1, Ingredients and Additives, for more information.

Finally, the PT domain is used to represent the actual results of testing the manufactured cigarette product for conformance to the tobacco product design parameters shown in PD above. PTCAT is a Required variable and is set to "DESIGN PARAMETER TESTING" for all records here. As described in the PD example, IGDCMPID is also used here to differentiate 2 records of the same test performed on each of 2 different types of tobacco that are ingredients of the tobacco product. Typically, applicants would submit data on each parameter in multiple replicates. For simplicity of review, only 1 replicate per parameter is shown. Note that PTREPNUM (repetition number) = 1 for all rows.
