Description
Curator's Comment: description was created based on several sources, including http://link.springer.com/article/10.1007/s40265-014-0285-6

Idelalisib is a first-in-class selective inhibitor of adenosine-5'-triphosphate (ATP) binding to PI3Kdelta kinase, resulting in inhibition of the P13K signalling pathway in malignant B cells. The compound is approved for the treatment of several types of blood cancer. Idelalisib is intended to be used in combination with rituximab as second or subsequent line therapy for the treatment of chronic lymphocytic leukaemia. The drug may cause fatal and/or severe diarrhea or colitis, hepatotoxicity, pneumonitis and intestinal perforation.

Indicated for the treatment of patients with: 1) relapsed chronic lymphocytic leukemia (CLL), in combination with rituximab, in patients for whom rituximab alone would be considered appropriate therapy due to other co-morbidities; 2) relapsed follicular B-cell non-Hodgkin lymphoma (FL) in patients who have received at least two prior systemic therapies; 3) relapsed small lymphocytic lymphoma (SLL) in patients who have received at least two prior systemic therapies.

 yes [IC50 76 uM]
yes (co-administration study)
Comment: Relatively few patients were coadministered CYP2C8, CYP2C9 or UGT1A1 substrates, but about 30% of patients enrolled in NHL and CLL trials were coadministered sensitive CYP2C19 substrates, including lansoprazole and omeprazole. The incidence of diarrhea and rash were higher in patients taking PPI (Section 2.1.1). These adverse events are associated with both PPI (1% to 4%) [PMC2014999] and idelalisib. The exposure to idelalisib is similar in patients taking ARA as compared to patients not taking these agents. Overlapping adverse events or an increased exposure to PPI (CYP2C19 substrates) could explain the increased incidence of adverse events.
