European Union approval has been recommended for duvelisib (Copiktra) for patients with relapsed/refractory chronic lymphocytic leukemia (CLL) or refractory follicular lymphoma (FL) who have received at least two prior lines of therapy.
Duvelisib is an inhibitor of phosphoinositide 3–kinase (PI3K) and is the first drug to act as a dual inhibitor of PI3K-delta and PI3K-gamma. These enzymes are involved in the proliferation and survival of malignant B-cell lines and primary CLL tumor cells and are involved in immunologic pathways in the tumor microenvironment of malignant B cells.
Duvelisib is already on the market in the United States; it was approved in 2018 for the same two indications and also for use in the treatment of small lymphocytic lymphoma (CLL/SLL).
