Cytochrome P450 (P450) induction is often considered a liability in drug development. Using calibration curve-based approaches, we assessed the induction parameters R3 (a term indicating the amount of P450 induction in the liver, expressed as a ratio between 0 and 1), relative induction score, Cmax/EC50, and area under the curve (AUC)/F2 (the concentration(More)
Methotrexate is the most commonly used drug to treat rheumatoid arthritis. Since clinical efficacy studies in rheumatoid arthritis are conducted on a background of methotrexate therapy, it is necessary to assess the potential of rheumatoid arthritis candidate drugs to perpetrate a drug-drug interaction (DDI) with methotrexate during development.(More)
Breast cancer resistance protein (BCRP) and multidrug resistance protein 2 (MRP2) can play a role in the absorption, distribution, metabolism, and excretion of drugs, impacting on the potential for drug-drug interactions. This study has characterized insect cell- and mammalian cell-derived ABC-transporter-expressing membrane vesicle test systems and(More)
BACKGROUND Neurologic involvement in mycosis fungoides is rare. Isolated case reports in the literature suggest the pattern and the natural history for such occurrences, while a literature summary can provide direction on diagnosis and management. Although case series may confirm such information, cohort data are required to establish an overall risk of(More)
Mast cells represent a potential source of interleukin-6 (ILlenge with SCF, bone marrow-derived cultured mouse mast 6) and other cytokines that have been implicated in host cells (BMCMCs) released amounts of IL-6 that were greater defense, tissue maintenance/remodeling, immunoregulathan 100-fold more than those produced by unstimulated tion, and many other(More)
