The following information helps you to find FDA Alerts and Pharmacist’s Applications to Practice quickly and easily. In cooperation with the Food and Drug Administration (FDA), and as a service to our members, HOPA periodically distributes information about newly approved therapies for cancer patients from FDA’s Office of Oncology Drug Products Director, Dr. Richard Pazdur to inform oncologists and professionals in oncology-related fields in a timely manner. Links to product labels will take you to relevant clinical information on the indication, contraindications, dosing, and safety. In sending this information, HOPA does not endorse any product or therapy and does not take any position on the safety or efficacy of the product or therapy described.

Along with HOPA’s Publications Committee, members also review new drug updates and provide analysis and research on the application of these new drugs or indications. Pharmacist’s Applications to Practice, or PAP, are listed after drugs that include the additional analysis. If you are interested in helping the Publications Committee with creating a Pharmacist's Application to Practice, please contact Jeff Price at jprice@hoparx.org.

You can also find additional information on FDA Alerts and Updates by listening to FDA Drug Safety Podcasts.

On November 15, 2019, the U. S. Food and Drug Administration approved zanubrutinib (BRUKINSA, BeiGene, Ltd.) approved for for adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.

On November 15, 2019, the Food and Drug Administration granted accelerated approval to zanubrutinib (BRUKINSA, BeiGene, Ltd.) for adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.

Efficacy was evaluated in BGB-3111-206 (NCT03206970), a phase 2 open-label, multicenter, single-arm trial of 86 patients with MCL who received at least one prior therapy. Zanubrutinib was given orally at 160 mg twice daily until disease progression or unacceptable toxicity. Efficacy was also assessed in BGB-3111-AU-003 (NCT 02343120), a phase 1/2, open-label, dose-escalation, global, multicenter, single-arm trial of B‑cell malignancies, including 32 previously treated MCL patients treated with zanubrutinib administered orally at 160 mg twice daily or 320 mg once daily.

The primary efficacy outcome measure in both trials was overall response rate (ORR), as assessed by an independent review committee. In trial BGB-3111-206, FDG-PET scans were required and the ORR was 84% (95% CI: 74, 91), with a complete response rate of 59% (95% CI 48, 70) and a median response duration of 19.5 months (95% CI: 16.6, not estimable). In trial BGB-3111-AU-003, FDG-PET scans were not required and the ORR was 84% (95% CI: 67, 95), with a complete response rate of 22% (95% CI: 9, 40) and a median response duration of 18.5 months (95% CI: 12.6, not estimable).

The most common adverse reactions (≥20%) included decreased neutrophil count, decreased platelet count, upper respiratory tract infection, decreased white blood cell count, decreased hemoglobin, rash, bruising, diarrhea, and cough. The most common serious adverse reactions were pneumonia in 11% and hemorrhage in 5% of patients. 

The recommended zanubrutinib dose is 160 mg orally twice daily or 320 mg orally once daily.
