Radataadam tadam4/2/2023 ![]() Using these standards is no longer a choice FDA, PMDA, and other regulators insist on it. ![]() If you’re using a CDISC-aware tool such as the Formedix clinical metadata repository and clinical study automation platform, to define your datasets, it will guide you towards compliance and report on any issues. There are a lot of rules in the CDISC content standards, so it’s important to check that you’re using them properly. This can help flag up problems with the CRF design, which can be corrected before actually rolling out the study.Ĭheck you are complying with SDTM, SEND, and ADaM Perform compliance checks to ensure adherence to standards.ĭefining your SDTM and SEND datasets early on in your study process enables you to map your source data to your intended submission datasets before actually collecting any data.Standardize mappings between different parts of the clinical lifecycle.You can even go a step further by defining CDISC-compliant organizational standards to increase data quality and simplify regulatory compliance. It also allows you to re-use your metadata from study to study in order to greatly reduce study build time. With built-in knowledge of the standards, this can help you define all your CDISC metadata right at the start of your study. The first step is to use a CDISC-aware metadata repository. But you can reduce the level of expertise required by making use of tools that understand CDISC and do the heavy lifting for you. It’s true that there’s a learning curve with these standards. This references the data in standardized ADaM datasets, making it simple to re-use analysis results metadata across different studies. This gives it the flexibility to be used for any type of analysis while providing a level of standardization that allows it to be easily understood by reviewers.Īnalysis Results Metadata for tables, listings, and figuresĬDISC has also standardized the description of Analysis Results Metadata (ARM) for describing tables, listings, and figures. Additional variables can be added within certain constraints defined by the model. It still has a core model and an implementation guide, but the model is not as proscriptive. It is based on the core SDTM model, allowing the submission of standardized domains that are not described in the Implementation Guide.ĬDISC’s Analysis Data Model (ADaM) is a bit different from SDTM and SEND. CDISC’s Standard for Exchange of Nonclinical Data (SEND) Implementation Guide is analogous to the SDTM Implementation Guide, defining the standard domains and variables that should be used when submitting non-clinical data. Non-clinical data has exactly the same issues as clinical data with regard to standardization, but the actual domains and variables required to represent the data are different. SEND – Standardizing non-clinical datasets Reviewers can understand your submission quicker, leading to fewer questions and a faster approval.There is a worldwide community to help with any questions, rather than relying on a small number of internal colleagues.There’s no need to learn organization-specific dataset formats.Consistency makes cross-study and cross-organization pooling and analysis easier.Data is more consistent between studies, so less per-study work, and less chance of errors.Using SDTM brings the following advantages: The SDTM Implementation Guide defines a set of standard domains based on the core model, such as AE (Adverse Events) and VS (Vital Signs). The core SDTM model defines different classes of domains (Events, Interventions, and Findings), each of which has a number of possible variables. And analysis datasets have a common data format to work from. This means that regulators have a consistent way of viewing data. This post gives a very brief overview of each model, how they fit in with the wider clinical trial process, and how you can get the maximum benefit from them.ĬDISC’s Study Data Tabulation Model (SDTM) defines standardized domains for submitting clinical data. The adoption of these standards is driven by regulators such as FDA and PMDA, who mandate that data must be submitted in these formats. Likewise, the Standard for Exchange of Nonclinical Data (SEND) defines standardized domains for non-clinical data. Another content standard, the Analysis Data Model (ADaM), aims to perform a similar function for analysis datasets. This is a content standard that ensures clinical data is submitted in a consistent manner, helping to reduce review time and facilitating cross-study analysis. It’s a safe bet that most people’s first introduction to CDISC standards is through the Study Data Tabulation Model (SDTM).
