Accelerated Approval for TG Therapeutics Ukoniq
FDA has granted TG Therapeutics accelerated approval for Ukoniq (umbralisib), a kinase inhibitor including PI3K-delta and casein kinase CK1-epsilon for treating adults with relapsed or refractory marginal zone lymphoma (MZL) who have received at least one prior anti-CD20-based regimen, and with relapsed or refractory follicular lymphoma (FL) who have received at least three prior lines of systemic therapy.
Approval was based on two single-arm cohorts — one involving 69 patients with MZL who received at least one prior therapy, including an anti-CD20 containing regimen, and the other in 117 patients with FL after at least 2 prior systemic therapies, an FDA release says. Efficacy was based on overall response rate (ORR) and duration of response (DOR). For patients with MZL, the ORR was 49% with 16% achieving a complete response, the agency says, adding that median DOR was not reached. For patients with FL, the ORR was 43%, with 3% achieving complete responses, and median DOR was 11.1 months, it says.
The prescribing information provides warnings and precautions for adverse reactions including infections, neutropenia, diarrhea and non-infectious colitis, hepatotoxicity, and severe cutaneous reactions.
