On November 1, 2021, Incyte announced that the US FDA has accepted the New Drug Application (NDA) for parsaclisib
.
Parsaclisib is a new-generation phosphatidylinositol 3-kinase delta (PI3K delta) oral inhibitor that is under research and is used for the treatment of relapsed/refractory follicular lymphoma, marginal zone lymphoma and sheath Patients with cell lymphoma
The FDA also granted priority review status for parsaclisib for the treatment of adult patients with relapsed/refractory marginal zone lymphoma and adult patients with treated mantle cell lymphoma who have received at least one CD20 inhibitor treatment
.
Non-Hodgkin's lymphoma (NHL) is a type of cancer that originates from lymphocytes.
Follicular lymphoma, marginal zone lymphoma and mantle cell lymphoma are all B-cell NHL
.
Follicular lymphoma and marginal zone lymphoma are indolent or slow-growing lymphomas; mantle cell lymphomas are aggressive or rapidly-growing lymphomas
The PI3K signaling pathway plays an important role in regulating cell growth, movement, survival, metabolism and angiogenesis
.
In human cancers such as breast cancer, colorectal cancer, and blood cancer, almost all PI3K signaling pathways are dysregulated
This application is based on positive data obtained from several phase 2 clinical trials
.
Please see the table below for specific data:
▲The effect of Parsaclisib in the treatment of different relapsed/refractory B cell NHL types (click to see the big picture, picture source: reference [2])
In all trials, parsaclisib was generally well tolerated and its safety profile was controllable
.
Incyte is planning to initiate a confirmatory phase 3 clinical trial
