New Graph Library

New Graph Library

A new graph library that provides the right graphs at the right time and with the right information has been developed by Cognigen Corporation, a leading provider of pharmacometric analysis and support services. Comprehensive graphical exploratory data analysis is essential to building pharmacometric models of drug behavior. Previously, deciding which graphs were required to describe the data and then creating a new program for each graph consumed excessive time from both scientists and programmers.

You WILL Innovate!

You WILL Innovate!

Few among us would think highly of a leader who directed us to innovate on demand. After all, innovation is something that comes from a mysterious creative force that strikes like lightning to the fortunate inventor, bringing with it fame and fortune. Think Bill Hewlett and Dave Packard; Steve Jobs and Steve Wozniak; Bill Gates; Mark Zuckerberg; or Tim Berners-Lee (huh?) [1].

Bendamustine pharmacokinetic profile and exposure-response relationships in patients with indolent non-Hodgkin’s lymphoma

Bendamustine pharmacokinetic profile and exposure-response relationships in patients with indolent non-Hodgkin’s lymphoma

Publication: Cancer Chemother Pharmacol
Division: Cognigen

The pharmacokinetic profiles of bendamustine and active metabolites were defined in patients with rituximab-refractory, relapsed indolent B-cell non-Hodgkin's lymphoma, and supported understanding of exposure-response relationships for efficacy and safety.

Model hurricanes.

Model hurricanes.

Although some meteorological modelers may disagree, it seems to me that models predicting development and movement of hurricanes are getting more and more accurate.

But…my projects are special.

But…my projects are special.

Scientists in the field of pharmaceutical research and development face a most daunting challenge. Our understanding of the diseases we work to treat grows more complex and perplexing with each new published study. Take, for example, the gusher of information coming out on Alzheimer’s disease. How can research findings from genetics, neurology, nutrition, protein chemistry, pharmacology, and epidemiology (just to name a few) be tracked, sorted, and used?
