Ukoniq™ (umbralisib) Receives Accelerated Approval for Adults with Marginal Zone Lymphoma and Follicular Lymphoma
Last updated: February 2021
Umbralisib is approved for use in people with MZL or FL that has relapsed after a previous treatment or not responded to treatment. Those with MZL must have been previously been treated with an anti-CD20-based regimen before starting umbralisib. Those with FL must have previously had at least 3 systemic therapies.1,2
Accelerated approval is granted to new drugs that are very promising and could make a positive impact on the treatment of serious conditions. There have been limited options for people with MZL or FL whose cancer had come back after treatment (known as recurrence or relapse). Umbralisib may be a new treatment option to help these people.2
The company that makes umbralisib, TG Therapeutics, is hoping to make the drug available in the United States soon.1,2
How does umbralisib work?
Umbralisib is a type of drug called a kinase inhibitor. Kinase is an enzyme that can have many jobs in healthy cells. However, kinase can be very active in certain types of cancer cells. A kinase inhibitor can block the kinase. This may prevent cancer cells or tumors from growing.4
Umbralisib is the first and only inhibitor of 2 specific kinases. The kinases that umbralisib targets are:2
- Phosphoinositide 3 kinase delta (PI3K-delta), which plays a role in cell division and survival
- Casein kinase 1 epsilon (CK1-epsilon), which plays a role in the development of cancer cells
By blocking these kinases, umbralisib may help slow the growth of cancer cells.2
Evidence for umbralisib
Umbralisib was approved based on results from a clinical trial. The researchers studied 2 groups of people: 69 with MZL, and 117 with FL.1
They found that about 50 percent of the people with MZL had a positive response to umbralisib. About 40 percent of the people with FL had a positive response to umbralisib. A positive response means their cancer shrank or disappeared after treatment with the drug.1
