Submitting Software Programs to the Regulatory Agencies, what should you know?

December 18, 2020

Can I submit software programs other than SAS? What software programs should I submit? Are sponsors required to submit executable programs?

Do I need to rename my software programs so that they all have the same extension e.g. “.txt”?

Can I make use of macros in my software programs and if so, should macros be part of the submission package?

What kind of documentations for software programs should I include in the submission package?

Do I need to follow any particular style and conventions when writing software programs that will be part of a submission package?

A single topic generates so many questions! Get the answers in this blog.

Therapeutic Area User Guidance – The hidden Gems

July 28, 2020

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:

  1. sponsors sometimes make bad or different interpretations of the standard
  2. lack of standards or use cases in specific disease areas or indication
The first issue has been addressed by a number of specific HA conformance technical guidance [1,2] and regular public webinars where the HAs presented to the Industry real examples of bad standards implementations [3]. For the second issue, it was soon clear that the gap to be fixed was bigger and required more investment and resources. The CDISC Therapeutic Area User Guidance (TAUGs) are an “attempt” to fill this gap and reduce interpretation, and misinterpretation, of the standards [4].

Highlights from the 2020 Virtual CDISC EU Interchange by Angelo Tinazzi - Part 2

April 27, 2020

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.

Highlights from the 2020 Virtual CDISC EU Interchange by Angelo Tinazzi

April 24, 2020

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.

Once upon a time Hansel and Gretel laid a trail of breadcrumbs which they followed to find their way back home.  Their story can be an allegory for the concept of traceability in clinical data where we need to  lay a clear path to ensure that the results we have created can be reproduced. This blog looks at some aspects of a presentation Lost in Traceability  by Angelo Tinazzi at the CDISC EU Interchange.
