Define.xml is "arguably the most important part of the electronic dataset submission for regulatory review," according to The FDA’s Technical Conformance Guide. It helps reviewers gain familiarity with study data, its origins and derivations, as well as sponsor-specific implementation of CDISC standards. In addition to the define.xml, the Technical Conformance Guide also asks that sponsors submit a stylesheet. A stylesheet transforms the define.xml into a human readable structure.

Have you ever wondered how Pinnacle 21 implements rules for ADaM validation? Below is a list of commonly asked questions.

1. Does Pinnacle 21 implement the validation checks published by CDISC?

   Yes, Pinnacle 21 rules are an implementation of CDISC validation checks. In fact, P21’s Trevor Mankus is a co-lead of the CDISC ADaM Conformance Rules subteam with P21's Michael DiGiantomasso, Michael Beers, and Sergiy Sirichenko as active members. Between 2011 and 2018 the subteam produced 4 versions of CDISC validation checks, with Pinnacle 21 supporting the industry by releasing 7 updates to the open source rule implementations. This close collaboration between Pinnacle 21 developers, ADaM team core members, and representatives from across the industry is what makes it possible to continuously improve rule definitions and implementations. Most recently, the subteam released CDISC ADaM Conformance Rules v2.0 which included support for IG 1.0 and IG 1.1.

2. Why do the message text and rule counts differ?

   CDISC check definitions are designed to serve as requirements to machine implementation, "a programmable test, written such that an affirmative response represents a failure of the requirement. This text is intended for use as a requirement specification which could be implemented in a variety of programming languages". P21's rule messages and descriptions, on the other hand, are designed for the end user to help them quickly identify and fix the cause of validation issue.

Released March 31, the new P21 Enterprise 4.0 provides more options for submitting study data to the Japanese health authority PMDA, plus better ways to manage validation issues and reports, as well as new validation rules and support for STDMIG 3.3.

P21 Enterprise 4.0 addresses concerns raised by our customers who submit data to both FDA and PMDA. Historically, regulators at the two agencies have embraced clinical data standards and conformance rules at different rates and degrees of severity.

Running data validations for PMDA has required a separate compliance strategy, plus extra time for validation and regulatory submission. Too often, sponsors worry that PMDA submission packages will fall short of reviewer expectations.

Now that the long-awaited SDTMIG 3.3 has been officially released, Pinnacle 21 team has eagerly began to implement validation rules for this new standard. As the first step, we performed a gap analysis for changes since SDTMIG 3.2. We excited to share our findings with the CDISC community, which you can find in the slides along with summary of changes below.

Define.xml is "arguably the most important part of the electronic dataset submission for regulatory review,” according to The FDA’s Technical Conformance Guide. It helps reviewers gain familiarity with study data, its origins and derivations, as well as sponsor-specific implementation of CDISC standards.

Last week, FDA published an updated version of Validator Rules for study data. There are many changes which we have reviewed and summarized for you.

The first change you’ll notice is that there are a number of new columns:

• FDA Validator Rule ID – a unique rule id that is now consistent across FDA, PMDA, and Pinnacle 21
• FDA Validator Message – validation messages produced by the Validator
• Publisher – the source of the business or conformance rule, FDA or CDISC

The FDA list now includes the conformance rules published by CDISC, which is the why the list has grown by 317 rules, from 163 to 480. The CDISC rule ids can be found in the Publisher ID column.

Next, the FDA added a reference to SEND-IG 3.1 to show how existing business and conformance rules apply to this standard. CDISC is still working on the conformance rules for SEND-IG 3.0 and 3.1, so this list could serve as a guide for implementers for the time being.

So how does this release effect you?

With the latest Pinnacle 21 Enterprise 3.4 release, we continue to bring efficiencies to your data standardization and compliance efforts. This release features a number of new enhancements and compliance checks that you have been asking for. This release also marks the formal roll-out of our new customer-centric initiative and a dedicated Customer Success Team.

We recently hosted a webinar presenting the new features. You can watch the video, access the slides, review the Q&A, or read the summary below.
