![]() For example, if the CRO estimates it will take two hours of clinical research associate (CRA) time to deliver a unit, but it ends up taking three hours instead, then profit quickly evaporates. The challenge is to precisely budget the time of professionals working to deliver those units. This means that the sponsor pays a fixed amount for each unit, regardless of the effort to deliver the unit. The problem is complex because sponsors typically pay CROs for deliverables on what is known as a “unitized” basis. To gain insight into the profitability problem let's look at how CROs and sponsors interact, and how difficult it can be to measure study profitability-and even more difficult to forecast. While top line revenue growth is good, growth of profitability is important to attract and retain top talent. This trend is expected to increase to 15%, according to industry reports.īut despite rapid growth, many CROs are seeing dramatic declines in profitability-up to 50% by some estimates. At this point, nlmixr is still very much in a testing stage and is under lively development.The pharmaceutical industry continues to outsource more clinical trials to contract research organizations (CROs) each year-resulting in CRO growth of over 10% annually in the last five years. The source is now available at along with a vignette, and the models and datasets used in the nlmixr/nlme poster to be presented at ACoP (W-66): nlmixr: an open-source package for pharmacometric modelling in R on Wednesday, 26 October, 2016, 7:30-9:30 am. nlmixr greatly expands the utility of existing packages (like nlme) by providing an efficient and versatile way to specify pharmacometric models and dosing scenarios, with rapid execution due to compilation to C++. nlmixr builds on Wenping's RxODE package for simulation of nonlinear mixed effect models using ordinary differential equations, by implementing parameter estimation algorithms like nlme, gnlmm and SAEM. Occams is very proud to be playing a supporting role in the release of nlmixr, an open source package for population PK and PKPD modelling developed by Wenping Wang and Yuan Xiong. If there is a more deserving candidate for the ISoP Leadership Award in 2017, we are hard pressed to think of one. ![]() If this were not enough, Rik is author and co-author of over 170 publications, including a number of original research articles, and is a key part of the team behind nlmixr,Ī new tool being developed for nonlinear mixed-effects modelling. It is safe to say that PAGE, and indeed the field of pharmacometrics in general, Of supporting student research, Rik has been key in the development of an untold number of our past, present and future peers. Instrumental in shaping its sharp focus on science and its long tradition Rik is the heart and soul of PAGE, having overseen the organization of Europe’s pharmacometrics conference since 1996. Rik is in good company - previous winners of this distinguished award include such luminaries in our field as Sandy Allerheiligen, Larry Lesko, Richard Lalonde, Hartmut Derendorf, William Jusko and David D’Argenio. The award will be presented at the opening of the ACOP8 meeting in Fort Lauderdale, Florida, on Sunday, 15 October, 2017, which we will all be attending. Vision for the future direction of the field. This award recognizes outstanding and sustained leadership, mentorship, and outreach contributions to the field of pharmacometrics and to the development of the strategic We are proud to announce that our very own Rik Schoemaker is the 2017 recipient of the International Society of Pharmacometrics (ISoP) Leadership Award!
