  • Patent number: 7292944
    Abstract: The present invention concerns methods and systems for improving the accuracy of predicting resistance of a disease to a therapy. In one embodiment of the invention, mean and standard deviation (SD) values of fold change in normalized sensitivity, relative to a laboratory wild type standard pathogen or malignant cell are calculated to demonstrate that the patient samples display inherently different degrees of variation in susceptibility to each therapy. In another embodiment, the 2×SD value for each therapy is used as the cut-off between sensitive (within normal susceptible range) and resistant (above normal susceptible range).

  • Publication number: 20070166747
    Abstract: The present invention concerns methods for measuring drug resistance by correlating genotypic information with phenotypic profiles. In one embodiment, a method for interpreting genotypic information is described wherein a genetic code is generated from a patient sample, a list of mutations known or suspect to play a role in the development of resistance to one or more drugs is obtained from the generated genetic code, a genotype database is interrogated for previous samples with similar mutations relating to said one or more drugs, a phenotype for said sample is located in a phenotype database, the mean change in inhibition is determined based on all the examples located in said phenotype database, a distribution of sensitivities of one or more drugs suitable for treating a specific indication is determined.
