  • Patent number: 8535946
    Abstract: The response of a patient with an enteropathic disease to therapy, particularly a candidate therapy in a clinical trial setting, is assessed by detecting the ability of the patient to metabolize an orally administered CYP3A substrate. The CYP3A metabolism may be monitored in a variety of ways. Conveniently, the appearance of a metabolite of the CYP3A substrate is detected in a patient sample over a period of time following oral administration, e.g. in urine, plasma, breath, saliva, etc. The CYP3A substrate is optionally labeled, e.g. with an isotopic, fluorescent, etc. label.

The CYP3A metabolism may be monitored in a variety of ways.
