PSI Launch & Lifecycle SIG Webinar: Do you want to stay single? Considerations on single arm trials in the post-regulatory space

Date: Thursday 5th October
Time: 11:00-12:00 BST | 12:00-13:00 CEST
Speakers: Yulia Dyachkova (Merck), Nathalie Barbier (Novartis) and Cornelia Dunger-Baldauf (Novartis).

Who is this event intended for? Statisticians working in any phase of research who want to learn more about influencing the conduct of single arm trials.
What is the benefit of attending? Attendees will have the chance to learn more about influencing non-statistical stakeholders to choose designs and data sources that will best address their questions. As the host SIG, we will also utilise this as an opportunity to get critical feedback from attendees which will help to shape ideas for an upcoming manuscript.


This event is free to both Members of PSI and Non-Members.

Do you really want to stay single? Single arm trials (SAT) are not preferred but often accepted by regulators in oncology and in rare disease when potential effects of new treatments are very large and placebo treatment is unethical. However, in the post-regulatory space, SAT are common, and perhaps even more poorly suited to address the questions of interest. We will present the most frequently asked questions in the post-marketing space, the reasons why SATs are not able to address these questions, and how statisticians might reasonably influence decision makers to consider alternatives.

This session is applicable to statisticians working in any phase of research who want to learn more about influencing decision making regarding SATs. Attendees will learn more about past, current and future uses of SATs; the contexts in which SATs will and will not meet objectives; and how to influence decision makers to consider alternatives. This session will be highly interactive and questions and feedback are absolutely welcome!
