This award recognizes outstanding and sustained leadership, mentorship, and outreach contributions to the field of pharmacometrics and to the development of the strategic vision for the future direction of the field. 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. 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.
Rik is the heart and soul of PAGE, having helped, and more recently led, the organization of Europe’s pharmacometrics conference since 1996. Instrumental in shaping its sharp focus on science and its long tradition of supporting student research, Rik has been key in the development of an untold number of our past, present and future peers. It is safe to say that PAGE, and indeed the field of pharmacometrics in general, would not be what it is without him. 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, a new tool being developed for nonlinear mixed-effects modelling. If there is a more deserving candidate for the ISoP Leadership Award in 2017, we are hard pressed to think of one. Congratulations, Rik!
Occams has just authored a new publication, and as it is open access, we can provide a direct download: Brivaracetam population pharmacokinetics in children with epilepsy aged 1 month to 16 years by Rik Schoemaker, Janet Wade and Armel Stockis, in the European Journal of Clinical Pharmacokinetics.
We are proud to announce that Julia Winkler has joined the Occams family, effective 1 January 2017. Julia brings a wealth of industry and consulting experience in pharmacometrics across a broad range of indications, strengthening our dream team even further. Welcome aboard, Julia!
We have secured a new domain and Occams now sits maturely at Occams.com. Our email addresses will be updated shortly, but you will still be able to contact us using the occams.eu extension!
On 9 December 2016 at 9:15, Anne-Gaëlle Dosne defended her thesis with the title Improved methods for pharmacometric model-based decision making in clinical drug development brilliantly at Uppsala University, and Rik Schoemaker was her external examiner.
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. 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. 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++.
The source is now available at https://github.com/nlmixrdevelopment/nlmixr 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. At this point, nlmixr is still very much in a testing stage and is under lively development. Get in touch, see us at ACoP to discuss ways you could contribute (Wenping Wang, Yuan Xiong, Justin Wilkins and Rik Schoemaker will all be there), or try it out for yourself, and experience the joy of a population modelling package within R! A live demo will be possible, so come see Rik if you are interested!
Occams will be represented at WCoP 2016 in Brisbane by Rik Schoemaker. Meet him there or come see his poster on nlmixr: an open-source package for pharmacometric modelling in R on Monday, 22 August, 2016, 12.15-1:15 pm. nlmixr is a highly exciting open-source development that allows non-linear mixed effect modelling using R and the nlme package, but implementing full dosing flexibility along with ordinary differential equations, and computational speed by compling to C. A live demo will be possible, so come see Rik if you are interested!
At Occams we believe in providing academic output next to our consultancy work, and we are therefore happy to announce that we have co-authored two publications over the last months:
- Peter L. Bonate, Malidi Ahamadi, Nageshwar Budha, Amparo de la Peña, Justin C. Earp, Ying Hong, Mats O. Karlsson, Patanjali Ravva, Ana Ruiz-Garcia, Herbert Struemper, and Janet R. Wade. Methods and strategies for assessing uncontrolled drug–drug interactions in population pharmacokinetic analyses: results from the International Society of Pharmacometrics (ISOP) Working Group. J Pharmacokinet Pharmacodyn (2016) 43: 123.
- Rik Schoemaker, Janet R. Wade, and Armel Stockis. Brivaracetam Population Pharmacokinetics and Exposure-Response Modeling in Adult Subjects With Partial-Onset Seizures. Journal of Clinical Pharmacology (2016). doi: 10.1002/jcph.761.
We are extremely proud and honoured that Occams is has been granted two oral presentations at PAGE 2016! One will be presented by Lutz Harnisch (Pfizer) in a collaborative project with Pharmetheus, Occams and Pfizer with the title Modelling and simulation of neurological endpoints (modified Rankin Scale [mRS] and National Institute of Health Stroke Scale [NIHSS]) to aid clinical trial design in intracerebral hemorrhage (ICH), and one will be presented by Rik Schoemaker (Occams) with the title Extrapolation of a Brivaracetam Exposure-Response Model from Adults to Children on work performed while at Exprimo in collaboration with UCB.
Occams is committed to supporting global training, research and development in the field of pharmacometrics. Our consultants are variously associated with PAGE and the International Society of Pharmacometrics (ISoP), and in 2016 we are proud to be sponsors of PAGE (www.page-meeting.org), WCoP (wcop2016.org) and PMX Benelux !
Occams will be represented at ACoP 2015 by Rik Schoemaker. Meet him there or come see his poster (T-50) on Modeling the Effect of Levetiracetam on Daily and Aggregated Seizure Counts in Adults and Children on Tuesday, October 6, 2015, 7.30-9.00 am.
