Introduction to Population Enrichment by Dr. Thomas Burnett

July 27, 2020

Cytel is conducting a webinar series on complex innovative trial designs. Dr. Thomas Burnett, Senior Research Associate in Medical and Pharmaceutical Statistics at Lancaster University, joined us as the presenter in the latest webinar from this series. In this webinar, “Adaptive Enrichment Designs in Clinical Development”, Dr. Burnett provides us a brief introduction to population enrichment and explains where it fits in clinical trials. He offers his insights on the topics of hypothesis testing and decision making, which is a key component of adaptive designs. You can also learn about a real-world case study (TAPPAS Trial) where this approach was used. Continue reading this blog for highlights from the webinar.

Why Consider a Synthetic or External Control Arm?

July 23, 2020

Just as there are numerous adaptations that fall within the umbrella of adaptive designs, there are several different statistical methods that can lead to the construction of a synthetic control arm. Cytel’s ebook, “Demystifying synthetic control arms”, is an effort to explain common strategies for their construction. Download the ebook by clicking on the button.

Webinar: Practical Model-based Approaches for Phase I Oncology Trials

June 24, 2020

Last week, Cytel conducted its third webinar in the new introductory webinar series on Complex Innovative Trial Designs. Our speaker, Dr. Satrajit Roychoudhury is a Senior Director, Statistical Research and Data Science Center at Pfizer. In this webinar, Dr. Roychoudhury gets into the basics of phase I designs in oncology trials, explains the caveats of frequently used traditional designs and provides insights on how implementing a model-based approach can enable a better statistical inference and decision-making. You can watch the replay of the webinar and access the slides by clicking on the button.

Why You Should Construct Primary Endpoints Using Bayesian Methods: Lessons from COVID-19

June 18, 2020

One of the revelations of the COVID-19 pandemic is that the flexibility and potential of Bayesian designs goes far beyond the benefits connected to informed priors. Rather a number of other benefits to Bayesian designs are sometimes under-appreciated. The importance of using Bayesian methods to choose composite endpoints, for example, particularly in longitudinal studies, can be overlooked when considering Bayesian and Frequentist options.

Cytel statisticians reflected on these benefits during a recent panel discussion.

Adaptive Bayesian Methods: The Secret Weapon in COVID-19 Vaccine Development

June 11, 2020

A recent Cytel panel led by Vice President of Strategic Consulting Natalia Muhlemann evaluated the role that Bayesian methods played in development of a COVID-19 vaccine. The wide-ranging discussion covered the structure and utility of platform trials and the role of master protocols in infectious disease vaccines development, but also addressed the importance of adaptive Bayesian methods in the search for COVID-19 therapies.

Bayesian Methods for Contending with Homogeneity and Heterogeneity in Real World Data

February 25, 2020

Over the past decade, a new trend began to emerge, changing the way that clinical trials are conducted. Whereas placebo-controlled randomized control

 trials remain the gold standard, in some situations, single arm trials have become an accepted way of assessing a new treatment intervention. Single arm trials establish clinical benefit by demonstrating the positive effects of a new therapy or treatment, without the need to use placebo or standard of care as a control. Instead, alternative approaches of establishing the comparison 
are used; these have become known as external controls or synthetic control arms (SCA henceforth) and include approaches leveraging real world data from various sources or evaluations of historical clinical trial data.
