Purpose
This SIG will have two connected topics:
- General biostatistics Neuroscience community
- Working groups on estimands in neuroscience and other topics in neuroscience
Publications and slide decks
The group did work on the impact of Covid-19 pandemic on clinical trials in Neuroscience and provides recommendations. This is thought to be a living document with regular updates.
The impact of Covid-19 on clinical trials in NS V1.0 final
Joint EFSPI/BBS Workshop on the
application of the estimand framework: A Neuroscience perspective
November 3, 2020
This seminar covers the use of estimands in Neuroscience. Neuroscience is a heterogeneous therapeutic area in which development pathways and study analyses can substantially differ between different indications. Efficacy is usually based on longitudinal assessments which makes the application of the estimand framework specifically interesting and rich with many specific aspects from which we all can learn a lot.
A European scientific interest group (SIG) sponsored by EFSPI and PSI is working out in some typical Neuroscience indications how to best apply the estimand framework. This work is in progress and the seminar will provide an overview on the status of the working group including an opportunity to discuss issues and provide feedback. Finally, since the SIG also worked on the impact of Covid-19 pandemic in Neuroscience this topic will also be covered in the seminar. The seminar is not an introduction into the estimand framework.

Objectives
Biostatistics Neuroscience community:
- To support/strengthen the role o biostatistics in the edvelopment of new medicine for Neuroscience
- To identify areas where collaboration between companies makes sense
Working group on estimands:
- Potential overview on how to formulate estimands in different CNS indications
- Link the estimand question to statistical analyses in general
- Define situations in which MMRM can still be used even when theoretically addressing a treatment policy estimand
- Alternative methods to MMRM for treatment policy estimands
- Sensitivity analyses
- Out of scope:
- Specific estimands for AD (separate working group under ASA)
- Future use of MMRM in AD (separate working group under ASA)
Outcome:
- White paper and/or publication
- If needed potential consultation with HAs to get agreement on new standard method replacing MMRM and/or agreement on continued use of MMRM under certain conditions
Note:
The working group on AD under ASA includes a substream on estimands in AD and possible replacements for MMRM. This work will however, unlikely cover all work needed for Neuroscience in general, as there are specific differences in AD versus overall Neuroscience.
Certain areas of high unmet medical need and restricted development options like rare diseases in Neuroscience would not be addressed by the AD working group.
Principles
Biostatistics Neuroscience community
- Meets regularly ~4 times a year via TC
- Arrange f2f meetings at conferences if possible
- Only few representatives from each company to participate
- Transparent to the outside world
- Open to large and small pharmaceutical industry
- Exchange methodological information
- Do not exchange molecule/project specific information
- Can initiate working groups for working on CNS specific methodological issues together where it makes sense to do it together
Working group on estimands
- Every company interested can join and add statisticians to the group
- Monthly TC to organise work would seem meaningful
Organisation
- Membership (see table below)
- Information sharing: via the EFSPI and PSI websites, EFSPI and PSI Newsletters, webinars, presentations at conferences, publications in mainstream journals.
