Umbralisib, sold under the brand name Ukoniq, is a medication for the treatment of marginal zone lymphoma (MZL) and follicular lymphoma (FL).[2] It is taken by mouth.[2]

The most common side effects include increased creatinine, diarrhea-colitis, fatigue, nausea, neutropenia, transaminase elevation, musculoskeletal pain, anemia, thrombocytopenia, upper respiratory tract infection, vomiting, abdominal pain, decreased appetite, and rash.[2]

Umbralisib is a kinase inhibitor including PI3K-delta and casein kinase CK1-epsilon.[2][3][4] Umbralisib was approved for medical use in the United States in February 2021.[2][5][6]

Medical uses

Umbralisib is indicated for adults with relapsed or refractory marginal zone lymphoma (MZL) who have received at least one prior anti-CD20-based regimen; and adults with relapsed or refractory follicular lymphoma (FL) who have received at least three prior lines of systemic therapy.[2][1]

Adverse effects

The prescribing information provides warnings and precautions for adverse reactions including infections, neutropenia, diarrhea and non-infectious colitis, hepatotoxicity, and severe cutaneous reactions.[2]


It has undergone clinical studies for chronic lymphocytic leukemia (CLL).[7][8] Three year data (including follicular lymphoma and DLBCL) was announced June 2016.[9] It is in combination trials for various leukemias and lymphomas, such as mantle cell lymphoma (MCL)[10][11] and other lymphomas.[12]

Umbralisib was granted breakthrough therapy designation by the U.S. Food and Drug Administration (FDA) for use in people with marginal zone lymphoma (MZL), a type of cancer with no specifically approved therapies.[13]

FDA approval was based on two single-arm cohorts of an open-label, multi-center, multi-cohort trial, UTX-TGR-205 (NCT02793583), in 69 participants with marginal zone lymphoma (MZL) who received at least one prior therapy, including an anti-CD20 containing regimen, and in 117 participants with follicular lymphoma (FL) after at least two prior systemic therapies.[2] The application for umbralisib was granted priority review for the marginal zone lymphoma (MZL) indication and orphan drug designation for the treatment of MZL and follicular lymphoma (FL).[2][14][15][16][17]
