The Food and Drug Administration has approved zanubrutinib (Brukinsa) for the treatment of mantle cell lymphoma (MCL) in adult patients who have received at least one prior therapy.
The approval is based on results from two separate studies; in a global phase 1/2 trial, patients with relapsed or refractory MCL who received zanubrutinib had an overall response rate of 84%, with 22% experiencing a complete response and 62% experiencing partial response. Median duration of response was 18.5 months. The ORR in the second study – a multicenter phase 2 trial – was also 84%, but with 59% experiencing a complete response and 24% experiencing partial response; duration of response was 19.5 months.
The most common adverse events reported during the trials were decreased neutrophil count, decreased platelet count, upper respiratory tract infection, decreased white blood cell count, decreased hemoglobin, rash, bruising, diarrhea, cough, musculoskeletal pain, pneumonia, urinary tract infection, hematuria, fatigue, constipation, and hemorrhage. The most common serious adverse events were pneumonia and hemorrhage.
Of the 118 patients with MCL treated with zanubrutinib over the two trials, 8 had to be discontinued because of adverse events.
The recommended dose of zanubrutinib is 320 mg, taken orally 160 mg twice daily or 320 mg once daily, with or without food.
“BTK [Bruton kinase] inhibition is an established mode of treatment for patients with MCL, but many patients treated with previously approved BTK inhibitors do not fully respond to BTK therapy or are forced to discontinue treatment early due to side effects. Today we have a new option for our adult patients who have received one prior systemic or targeted therapy and are living with MCL,” Luhua (Michael) Wang, MD, clinical trial investigator and professor in the department of lymphoma and myeloma at the University of Texas MD Anderson Cancer Center, Houston, said in a statement.
