Abstract : This report describes technical work accomplished and information gained in performance of contract number DAMDl786-C-6150, entitled Analysis of Investigational Drugs in Biological Fluids - Method Development and Routine Assay, for the US Army Medical Research and Development Command (USAMRDC). We were able to complete ten projects for determination of test article concentrations in terms of method development, validation, and characterization. We demonstrated sensitivity, specificity, linearity, lack of interferences, accuracy, and reproducibility of the analytical method, described the extent of recovery for the method, and reported on the stability of compounds of interest in specimens during storage and drug analysis. Methods developed were such that a single technician could complete at least 15 clinical samples in one day. These methods were robust and portable enough to be transported to other laboratories. Six projects on ten compounds were begun during the contract period, one of which was cancelled, and the remaining five have reached various stages of completeness at the end of the contract period. Routine analyses of samples were performed for 33 studies (or pilot studies) designated by WRAIR. The breakdown of routine analyses studies by compound(s) follows: Halofantrine and/or WR 178,460,8 studies; Mefloquine 3 studies, Physostigmine and/or Eseroline, 6 studies; Pyridostigmine, 10 studies; WR 238605,3 studies; and WR 6026 and/or WR 211789,3 studies.
