Overcoming statistical challenges in rare disease drug development

Regulatory agencies like the FDA require substantial evidence of the drug’s effectiveness for its intended use and sufficient information to conclude that the drug is safe.  However, flexibility is given in how the standard can be met given the challenges associated with the limited number of subjects available in rare disease.

Study-Size Adjusted Percentages in Integrated Adverse Event Displays

To those of us who regularly create or review adverse event (AE) incidence tables for randomized controlled trials, it may come as a surprise that your typical AE incidence table can be misleading if data was combined from more than one trial. This is due to “Simpson’s paradox,” which, simply put, is the phenomenon that the mere grouping of data can introduce confounding or bias otherwise not present.

How to estimate the sample size for your next study from a publication with nothing but p-values and Ns

As statisticians, we’re frequently asked to do power and sample size calculations from very thin data. Often, we’re given nothing but an ancient publication containing a few p-values, an occasional mean, and maybe a standard deviation (if we’re lucky). Back calculating something meaningful in these situations can seem intimidating, but it turns out that most standard sample size software can do the work for us when used unconventionally. We’ve outlined 2 such unconventional uses.

Innovative Designs in Early-Stage Studies

Innovation in early-stage studies presents the best opportunity to streamline the drug development process. Such designs may not only reduce costs and accelerate timelines but give us better flexibility to address the questions of interest in an increasingly evolving clinical development landscape.

Transitioning Trials Approved under the Clinical Trials Directive to the Clinical Trials Regulation and CTIS

The new European Union (EU) legislation regulating clinical trials harmonises the processes for assessment and supervision of clinical trials throughout the EU. It enables sponsors to submit 1 online application via a single platform (CTIS) for approval to run a clinical trial in several European countries, making the conduct of such multinational trials more efficient.
