The National Academies of Sciences, Engineering, and Medicine are hosting a series of workshops looking at how real-world data can be converted to reliable real-world evidence to improve patient outcomes. Professor Sir Rory Collins spoke at the recent workshop and argued that rather than placing greater reliance on observational data, it would be much better to make it much easier to do randomised trials properly.

Professor Rob Califf, in a recent talk at the National Academies of Sciences, Engineering, and Medicine workshop on “real-world evidence” highlighted the failures of the current healthcare evidence generation system and presented a new approach to conducting randomised trials. You can watch the talk here.
Two of the key principles behind MoreTrials to do more trials better can be summarised as “focus on those things that matter” and “one size does not fit all.” This is very similar to the concept of defining upfront what matters for each randomised trial at the heart of Quality by Design (QbD).
QbD defines trial quality as the avoidance of errors that matter to decision making with monitoring playing a central role in evaluation and improvement. Note that not everything matters only those errors that are identified upfront.
QbD is a proactive task. In simple terms, QbD identifies before the start of a trial those critical factors that affect quality and puts in place effective processes to monitor these factors during the course of the study and, where needed, take corrective action. This is done for each individual trial.
This individualised approach is in stark contrast to the one size fits all approach of most regulatory guidelines. By setting out detailed procedures that need to be followed most guidelines, ICH-GCP is a good example of this, lack any real flexibility. By contrast, at MoreTrials we want to develop guidelines that focus on principles rather than process. At the level of the individual trial this allows for flexibility in how things get done. An example of this would be the contrast between setting out a principle in a guideline to “record informed consent” compared to an inflexible approach that stipulates the detailed process that needs to be followed in order to record informed consent.
Focusing guideline development on principles rather than detailed process allows for the flexibility that is part of the QbD approach. At the level of the individual trial this flexibility will allow more and better trials to be conducted.

The ICH plans announced at the start of this year to further revise ICH-GCP – so called “GCP renovation” – set out a strategy to first revise ICH E8, “General considerations for clinical trials” before commencing with a further and more substantial revision of ICH-GCP (E6). This seems like a sensible approach, but given the fact that relatively little is known about E8, in this article I want to look at this guideline more closely.
