We have written on the blog in the past about the value that a statistical consultant can bring to your team, and to the overall clinical development process. Statistical consultants can be instrumental to the success of your development program, providing a variety of input from creating innovative trial designs that improve information quality and efficiency, to supporting regulatory...

By Esha Senchaudhuri

An important trend in clinical development involves integrating strategic pharmacometric analysis with program level decision-making, to make the most use of available data. This can occur in various forms, from leveraging preclinical data for go-no-go decision making [1], to the need for improved comparative effectiveness frameworks [2].

Here we have five reasons why you...

Last month was the eighth American Conference on Pharmacometrics (ACoP8) in Florida, a key event on the calendar for Cytel’s Quantitative Pharmacology and Pharmacometrics subject matter experts.

Cytel was delighted to contribute to the event this year and present two posters. This was excellent opportunity to share our knowledge and innovative research, alongside networking with likeminded...

Model-informed drug development has been defined by Richard Lalonde ( Lalonde, 2007) (1) as “Development and application of pharmaco-statistical models of drug efficacy and safety from preclinical and clinical data to improve drug development knowledge management and decision-making”. It has  been identified by the FDA as an important way to help reduce attrition and uncertainty in drug...

The Population Approach Group in Europe (PAGE) represents a community with a shared interest in data analysis using the population approach. Each June, a meeting of the community is held at a different European location. At this year's meeting in Budapest, Hungary, Cytel's Director of Quantitative Pharmacology and Pharmacometrics, Cecilia Fosser, showcased innovative work on creating model...

Nonlinear Mixed Effects Modeling (NONMEM) is a type of population pharmacokinetics/pharmacodynamics (popPK/PD) analysis used in Clinical Pharmacology research. The population PK approach combined with pharmacodynamics modeling, allows integrated analysis, interpretation, and prediction of the drug’s safety, efficacy, dose-concentration relationship, and dosing strategy.

Challenge

Our client had the following key questions which they wanted our pharmacometrics group to address for an upcoming phase 2 trial of their ulcerative colitis compound .

1) Can knowledge from pre-clinical and Phase 1 data inform on the optimal range of doses for an upcoming Phase 2 dose-ranging study?

2) How may the dose response observed in PD markers in Phase 1 healthy volunteers...

Unlike statistics which has been around in some form for hundreds of years, pharmacometrics is, by comparison, a relatively new discipline and only entered the clinical development world in the last 30 years. Situated at the intersection of mathematical modeling, simulation, and big data, pharmacometrics leverages the best practices of translational research to generate clinical development...

Drug development is an expensive and risky business.  To maximize a compound’s ultimate chances of commercial as well as regulatory success it’s imperative that sponsors are building up a strong understanding of its characteristics relative to competitors.  This knowledge can support critical decisions along the development path, such as optimizing dosing, and selecting the best active...

Exposure-response data gained from clinical studies can provide a basis for model-based analysis and simulation, helping to predict the expected relationships between exposure and response.  Using this approach, it may be possible to optimize dosage regimens and to individualize treatment in specific patient subsets for which there are limited data.  In this blog, we examine a case study of...
