The Cytel blog keeps you up to speed with the latest developments in biostatistics and clinical biometrics.
“A good start is half the battle” (the Before) when submitting data to the FDA and there are a couple of cherries to put on top (the After) when your regulatory group has finally submitted the eCTD to the FDA . A good start is to have early discussions with the agency by regularly meeting them and sharing the status of your clinical data standards. While, the cherry on the top is the continuous support you need to guarantee to your submission project to promptly react when the reviewers come back with questions and additional requests during the review process.
CDISC standards have been around for a while with the first SDTM Standard version released in 2004. However, it was only in the last decade that it became “The Standard”, particularly when Health Authorities (HA), such as the US FDA and Japanese PMDA, made it a requirement for data submissions to support most of the regulatory requests for market approval. Additionally, most of the Pharma companies made the CDISC standards a part of their operational data model and consequently, the number of studies using the CDISC standards increased across phases of development.
The benefit of receiving data in standard formats was soon recognized by HA reviewers as they now require lesser time to understand the structure of the data they receive. Integration of data provided by different sponsors, for example on the same indication, for better understanding of safety signals, has become possible with data submitted in standard CDISC format.
However, the HAs such as the US FDA, soon realized that this was not enough, for two main reasons:
- sponsors sometimes make bad or different interpretations of the standard
- lack of standards or use cases in specific disease areas or indication
From the time the COVID-19 outbreak was declared a pandemic, the number of studies conducted around the world to either diagnose, prevent or treat the virus literally exploded (1570 as on today, according to the Cytel Global Coronavirus COVID-19 Clinical Trial Tracker1).
Moreover, the pandemic impacted the regular schedule of ongoing clinical trials. Health authorities such as the FDA, promptly provided recommendations in the form of questions and answers on how to handle “disruptions” due to the pandemic2. These disruptions include a range of challenges including skipped assessments or study withdrawal.
“CDISC launched a task force in an effort to support CDISC members and the research community as they work tirelessly to discover critical breakthroughs to treat COVID-19 …. The task force was launched with the goal of developing Interim User Guide and Related material” said David Bobbitt, CDISC CEO, in an interview with Outsourcing-Pharma.com3. On April 21, 2020, the task force released two guidances. In this blog, I provide you with a quick summary of what these guidances address.
The two guidances are:
- Guidance for Ongoing Studies Disrupted by COVID-19
- CDISC Interim User Guide for COVID-19

In the first part of this two-parts blog, I speak about how the European CDISC Committee (E3C) together with CDISC converted our physical event into a virtual one and was held on April 1-2, 2020. I provided a summary of the updates received from the three main health authorities - the US FDA, the Japanese PMDA and the European EMA.
This post offers an overview of the other sessions I attended at the 2020 Virtual CDISC EU Interchange. The agenda was well planned and organized. The distinguished speakers were extremely prepared and answered numerous questions after their presentations. Continue reading for further highlights from the event.
In early March, when countries around the world started implementing lockdowns, the European CDISC Committee (E3C) together with CDISC decided to cancel our physical event in Berlin, planned for April 1-2, 2020. It was a tough decision, but unavoidable and necessary.
We did not let this dampen our spirits and immediately came up with an alternative plan – go virtual with the event! In only two weeks the team managed to pull together a revised program and the registrations were opened on the CDISC website. The scale of the event went from being Europe-only to Global, and around 300 people attended it worldwide. In the end, the event was a hit. Everything worked out very well, with no major technical disruptions and the speakers respecting the allocated time slots.
In this two-part blog post, I share a summary of the sessions I was able to attend, while simultaneously ensuring business continuity for my regular projects.

October 3, 2019 was an important day for the ADaM team as it marked the release of the ADaM Implementation Guidance (Ig) 1.2. Download the new guidance from the CDISC website here.
In 2018, several previews of the new Ig were made at CDISC Interchanges all around the world and at PhUSE conferences, it was only a few weeks ago that the final version was released. At first glance, the new Ig does not seem to contain a lot of new concepts and ideas. However, a critical and in-depth review clearly shows the efforts of the entire team to release this new Ig. Creating a new standard or releasing a new version of an existing standard is not an easy job. You need to ensure that you do not introduce anything that contradicts any of the existing CDISC standards. This includes, not only new variables but also any changes in existing sentences or adding entirely new sections that may cause misinterpretations or discrepancies. Moreover, every standard team member comes with their own background, company needs, and specific indication needs. It is not always easy to propose a solution that can satisfy everyone on the team.
