single-patient AUC

From: Markus Joerger Date: September 02, 2012 technical
dear NM-community, Is NONMEM reliably used for single-patient AUC-calculation in cases of linear PK, or is e.g. WinNonLin (or similar software) preferred in such cases? best regards, Markus -- Markus Joerger MD PhD Associate Professor Medical Oncology&Clinical Pharmacology Cantonal Hospital 9007 St. Gallen Switzerland [email protected] [email protected] Phone: +41-765591070 Fax: +41-714946325

Re: single-patient AUC

From: Bill Denney Date: September 02, 2012 technical
Hi Markus, Typically, AUCs are calculated using software like WinNonlin because it is both simpler and more objective (the model is simple and specified a priori). Generally, the model is just used as the linear-up, log-down trapezoidal rule with personal (or corporate) preferences on handling BLQ and extrapolation to infinity. Thanks, Bill

RE: single-patient AUC

From: Mats Karlsson Date: September 02, 2012 technical
Dear Markus, I guess it depends on how you plan to make the estimation: 1) If it is by NCA, other programs will do this 2) If it is as model-based, non-linear regression, many programs will do it (incl NONMEM) 3) If you want to analyse the individual data using a previous population PK model as prior, NONMEM and other non-linear mixed effects models are probably preferable.

Dear NM-Users, I am doing a simulation using R, in which the within and between subject variations, "EPSILON" and "OMEGA", are needed. They are automatically listed in the ***.lst file of the NONMEM outputs. Is there a way I can read them from my NONMEM output into R?

Dear Shirley, If you have access in your group* to the Connect module of Phoenix you will find that NONMEM jobs executed via this interface will automatically extract certain information including these as tables for use in other 'downstream' objects in your workflow which could include R. It also supports PsN, Xpose, SAS, SigmaPlot and S-plus. There are some webinars (e.g. http://www.pharsight.com/events/eventsonline_archive.php#replay_049) that can expand on my comments if you are interested and an example project in the User Forum. Best regards, Simon. *I know your organisation already has some float licenses for this. Alterantively we could set you up with an evaluation license. ___________________________________ [email protected]<mailto:[email protected]> Senior Scientific Consultant Pharsight- A Certara(tm) Company Get tips and discuss Pharsight products with other users; www.pharsight.com/extranet ___________________________________ http://www.pharsight.com/training/training_upcoming.php Satellite workshops at PAGE, 5 June 2012, Venice, Italy. 08:30 - 12:30 "Phoenix Connect: Linking Modeling and Simulation Tools, including NONMEM, R, Xpose & PsN, in Phoenix Workflows" https://pharsight.securesites.com/training/course_display_new.php?details_id=98. 13:00 - 17:00 "An Overview of the QRPEM Algorithm in Phoenix NLME" https://pharsight.securesites.com/training/course_display_new.php?details_id=99.

Dear Shirley, If you don’t have access to expensive software like Phoenix you can use this R-script that reads your .lst file and extracts the EPSILON and ETAs. Note: this script gives you the CORR matrix, if you want the COV matrix just change it in the 2nd and 3rd row of the script. #------ Extract EPSILON & ETAS from .lst --- lst <- readLines(paste("YOUR_LIST_FILE.lst",sep="")) # Read in .lst file row_startOMEGA <- grep("OMEGA - CORR MATRIX FOR RANDOM EFFECTS - ETAS *******", lst, fixed=T) # Find the start of CORR MATRIX - ETAS row_startSIGMA <- grep("SIGMA - CORR MATRIX FOR RANDOM EFFECTS - EPSILONS ***", lst, fixed=T) # Find the start of CORR MATRIX - EPSILON n_ETAS <- (row_startSIGMA-row_startOMEGA-7)/3 # Find number of ETAs, 7 "emtpy" rows, 3 rows per ETA CORRMATRIX_ETAS <- lst[row_startOMEGA:row_startSIGMA] # Extract the corr matrix - ETA CORRMATRIX_ETAS <- CORRMATRIX_ETAS[seq(7,(n_ETAS-1)*3+7,3)] # Extract the numbers in the matrix ETAS <- signif(as.numeric(gsub("\\D", "", CORRMATRIX_ETAS)),3)/1000 # Remove correlations, signif to get 3 significant digits, /1000 to get % ETA_character_vector <- paste(rep("ETA",n_ETAS),seq(1,n_ETAS,1),sep="") # Create a character vector containing ETAn ETAS <- data.frame(ETAS,ETA_character_vector) # Create data frame CORRMATRIX_SIGMA <- lst[row_startSIGMA+6] # Extract the corr matrix - EPSILON EPS <- signif(as.numeric(gsub("\\D", "", CORRMATRIX_SIGMA)),3)/10000 # /10000 to get % #------ End of script ------------ Best regards, Oskar Alskär _____________________________________________ Description: uu logo red 60 Oskar Alskär, MSc Pharm PhD Student Pharmacometrics group Department of Pharmaceutical Biosciences Uppsala University Box 591 75124 Uppsala Sweden [email protected]

Shirley, The R package "metrumrg" has a function "rlog" that returns a data.frame containing thetas, omegas, sigmas, mofv, etc for one or more NONMEM runs. Available on CRAN. Contact me offline for any additional help. Kind regards, Tim Bergsma Metrum Research Group, LLC [email protected]

Shirley, An interesting new possibility is the xml output. Using the XML package from CRAN, this can be read in R as follows: library(XML) x <- xmlTreeParse("yourmodel.xml", getDTD=F) r <- xmlRoot(x) To see what is there: names(r[['nonmem']][['problem']][['estimation']]) So for example: xmlValue(r[['nonmem']][['problem']][['estimation']][['final_objective_function']]) Best regards, Erik
