Umbralisib, sold under the brand name Ukoniq, is a medication which was previously used to treat marginal zone lymphoma (MZL) and follicular lymphoma (FL).[1][3] It was taken by mouth.[1]

Common side effects include kidney problems, diarrhea, tiredness, nausea, low neutrophils, muscle pain, low platelets, low red blood cells, upper respiratory tract infection, and rash.[1] Other side effects may include infections, liver problems, and allergic reactions.[1] Use in pregnancy may harm the baby.[1] It is a kinase inhibitor that blocks PI3K-delta and casein kinase CK1-epsilon.[1]

Umbralisib was approved for medical use in the United States in 2021.[1] However, due to concerns of worsened outcomes it was removed from the market in 2022.[2] Efforts to license in Europe and the United Kingdom have been discontinued.[3]

Medical uses

Umbralisib was 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.[1][4][2][5]

On April 15, 2022, TG Therapeutics announced the voluntary withdrawal of Ukoniq (umbralisib) from sale for its approved use in the treatment of marginal zone lymphoma and follicular lymphoma. Furthermore, the company withdrew the pending Biologics License Application (BLA) and supplemental New Drug Application (sNDA) for the treatment of chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) which utilized umbralisib in tandem with ublituximab, known as the "U2" regimen. The decision was based on the most recent overall survival (OS) data from the Phase 3 trial, Unity-CLL, that illustrated and increasing imbalance in OS.

Dosage

It was taken at a dose of 800 mg once per day.[1]

Side effects

Side effects include infections, neutropenia, diarrhea and non-infectious colitis, hepatotoxicity, and severe cutaneous reactions.[4]

History

It has undergone clinical studies for chronic lymphocytic leukemia (CLL).[6][7] Three year data (including follicular lymphoma and DLBCL) was announced June 2016.[8] It is in combination trials for various leukemias and lymphomas, such as mantle cell lymphoma (MCL)[9][10] and other lymphomas.[11]

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.[12]

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.[4] 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).[4][13][14][15][16]

Society and culture

In June 2022, due to safety concerns, the U.S. Food and Drug Administration (FDA) withdrew its approval for Ukoniq (umbralisib).[2]

Updated findings from the UNITY-CLL clinical trial show a possible increased risk of death in people receiving Ukoniq.[2] As a result, the FDA determined the risks of treatment with Ukoniq outweigh its benefits.[2] Based upon this determination, the drug's manufacturer, TG Therapeutics, announced it was voluntarily withdrawing Ukoniq from the market for the approved uses in MZL and FL.[2][17]
