The effect on sotrastaurin pharmacokinetics of strong CYP3A inhibition by ketoconazole.

Aims: Sotrastaurin is an immunosuppressant that reduces T-lymphocyte activation via protein kinase C inhibition. The effect of CYP3A4 inhibition by ketoconazole on the pharmacokinetics of sotrastaurin, a CYP3A4 substrate, was investigated.

Methods: This was a two-period, single-sequence crossover study in 18 healthy subjects.
