The role of the regulatory committee is to provide the PSI/EFSPI viewpoint on regulatory issues. This includes promoting best practice, reviewing regulatory policy and guidelines, driving debate on future guidance, and engaging with statisticians in European regulatory agencies.



As you all know, statisticians across the globe and across industry are actively involved in trying to understand and address the impact of COVID-19 on pharmaceutical development, including the safety of the patients in our trials and the integrity and interpretability of the data we collect. There are many ongoing efforts, where members from PSI and other organizations, as well as companies, are partnering to address the impact on clinical trials – thank you for all your efforts! A number of regulatory agencies and other groups have issued guidance in response to the impact of COVID-19 on clinical trials and clinical research. This includes the FDA, EMA, CTFG and others. Please check the regulatory agency websites to obtain the latest guidance. The PSI/EFSPI regulatory committee has reached out to European regulators to volunteer our help, and to discuss and work on specific topics. The committee also collaborated with EFPIA to review and collate comments on the draft points to consider document that the EMA Biostatistics Working Party (BSWP) released, 'Points to consider on implications of Coronavirus disease (COVID-19) on methodological aspects of ongoing clinical trials'. Some of the key items from the consolidated comments were as follows...[Read More]


FDA released the draft guidance Demonstrating Substantial Evidence of Effectiveness for Human Drug and Biological Products. The document is intended to provide guidance on the evidence to be provided to demonstrate effectiveness when planning to file new drug applications (NDAs), biologics license applications (BLAs), or applications for supplemental indications, and complements and expands on the 1998 guidance entitled Providing Clinical Evidence of Effectiveness for Human Drug and Biological Products (the 1998 guidance).





During 2019 the regulatory committee held five regular committee meetings and met with the MHRA statisticians. The committee coordinated the review of several regulatory guidance documents (more detail below). Committee members contributed to EMA and industry workshops, as well as webinars; helped organize the 4th EFSPI workshop on regulatory statistics held in Basel as well as a plenary session on Regulatory and HTA hot topics at the PSI conference in London.

In July the chair of the regulatory committee transferred to Christoph Gerlinger from Anna Berglind, who is now the co-chair of the committee.


Meeting with Regulators 

On Wednesday 13 November 2019 the PSI/EFSPI Regulatory Committee met with the MHRA statisticians in London for an informal exchange of statistical topics important for both regulators and industry. There was great discussion on topics such as estimands, subgroup analyses and predefined Quality Tolerance Limits as well as quality attributes, model-based dose escalation studies, real world evidence, use of historical controls and the lack of statisticians in many ethics’ committees in England.

The planned meeting with EMA’s biostatistics working party was postponed to 2020 due to EMA’s business continuation plan for Brexit.


Expert Groups

The regulatory expert working group on subgroup analyses was still active during 2019 and continued the work on developing best practice for subgroup analyses.


The 4th Regulatory Workshop 

The 4th Regulatory Statistics Workshop took place in Basel, Switzerland on the 23rd and 24th September 2019. Approximately 230 delegates attended the workshop with great discussion between regulators, academics, and industry on real-world data, analysis of safety in clinical trials, estimands, modern approaches for rare disease and contributed short topics.



On July 4th, 2019, the PSI/EFSPI Regulatory Committee organized the Webinar: ‘Adaptive design: updated draft FDA guidance and its implications’. In the webinar Jürgen Hummel (PPD) shared an overview of the FDA’s updated guidance on adaptive design for clinical trials of drugs and biologics, and discussed implications for industry. This was followed by the introduction of an open-source statistical software for adaptive designs, RPACT (an R package available on CRAN that enables the design and analysis of confirmatory adaptive clinical trials) led by Kaspar Rufibach (Roche). Kit Roes (Working Group Methodology of the Dutch Medicines Evaluation Board and member of the EMA Biostatistics Working Party) closed the webinar by commenting on the guidance from a European Regulatory perspective.

In addition, Anna Berglind chaired a joint PSI/DIA Journal Club Webinar on Subgroup Analyses on October 24, where Cynthia Huber from the University of Göttingen discussed her paper 'A comparison of subgroup identification methods in clinical drug development: Simulation study and regulatory considerations', and Christoph Muysers and Bodo Kirsch (both Bayer) shared a systematic approach for post hoc subgroup analyses with applications in clinical case studies.


Training course

Two members of the commitee (Chrissie Fletcher and Kerry Gordon) joined James Matcham (AstraZeneca) and Caroline Pothet (GSK) in delivering the two day training course "ICH for Statisticians" on 19/20 November. Of note, 100% of attendees said they would recommend the course to others.


Review of Guidelines

The regulatory committee collated comments on the following documents during the year:
