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...

SAS and NONMEM - a marriage made in heaven?

Posted by Cytel

Jan 5, 2017 8:45:00 AM

 

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.

Pharmacometrics tools of the trade: 4 factors to consider

Posted by Cytel

Nov 1, 2016 10:02:00 AM

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...

Case Study:Exposure Response Modeling in Hematology

Posted by Cytel

Sep 13, 2016 10:15:00 AM

 

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...
