Analysis Dataset Model (ADaM)

The CDISC ADaM Team has published “Statistical Analysis Dataset Model: General Considerations Version 0.7” for comment. This version is posted for general comments from September 15, 2004 to October 15, 2004. Please submit comments using the comment spreadsheet provided below to Dave Christiansen at davechristiansen@cableone.net.

Version 1.0.0 will incorporate comments, suggestions, and corrections received from the general comment period specified above and will become the official implementation version to supersede all prior ADaM model specifications. Each of the existing four statistical models (Change from Baseline, Survival, Categorical and Linear Model) will be revised and will refer to the General Considerations Version 1.0.0 document. Additional models, including Baseline Characteristics and Adverse Events will then be developed. These documents pertaining to each statistical model will provide additional guidance and examples for the specific statistical methodology.

ADaM's Objectives

The Analysis Data Modeling (ADaM) team has developed a guideline and several examples for analysis datasets used to generate the statistical results for a regulatory submission.

Upon reviewing these documents, please submit your comments via our Public Discussion Forum.

ADaM_Guidelines_V1.pdf Guideline for the Creation of Analysis Files and Documentation of Statistical Analyses for Submission to the FDA: This document provides guidelines for the creation of analysis data sets and associated documentation that are submitted to the FDA statistical reviewer in support of the primary and important secondary study objectives. These guidelines discuss the variety of issues that should be considered when submitting information to aid the statistical review of the submission.
CFB_Model_V1.pdf Example of Information to be supplied for a Change From Baseline Statistical Analysis: This first example presents guidelines for a familiar percent change from baseline analysis frequently used by industry statisticians. Future examples will present other frequently used statistical analyses.
CAT_13mar03.pdf Example of Information to be supplied for a Categorical Data Analysis: This example considers the case of a binary endpoint, such as a comparison of the proportion of patients who respond (or fail to respond) to treatment.
TTE_Model_v04242003.pdf Example of Information to be supplied for a Time-to-Event Data Analysis: This example considers the occurrence of the first event only, but may not preclude the development of analysis files for analyzing recurrent event data through straightforward extensions.
