FDA Drug Safety Podcast
Welcome to the FDA Drug Safety Podcast for health care professionals from the Division of Drug Information. On June 1, 2022, the FDA withdrew its approval for the cancer medicine Ukoniq (active ingredient umbralisib) due to safety concerns. Ukoniq was approved to treat two specific types of lymphoma: marginal zone lymphoma (MZL) and follicular lymphoma (FL).
Updated findings from the UNITY-CLL clinical trial continued to show a possible increased risk of death in patients receiving Ukoniq. As a result, we determined the risks of treatment with Ukoniq outweigh its benefits. 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.
Health care professionals should stop prescribing Ukoniq and switch patients to alternative treatments. Inform patients currently taking Ukoniq of the increased risk of death seen in the clinical trial and advise them to stop taking the medicine. In limited circumstances in which a patient may be receiving benefit from Ukoniq, TG Therapeutics plans to make it available under expanded access.
Side effects involving Ukoniq and other medicines should be reported to FDA’s MedWatch program at www.fda.gov/medwatch.
