Introduction to Zanubrutinib
Zanubrutinib, marketed as Brukinsa, is a small molecule inhibitor of Bruton's tyrosine kinase (BTK), a crucial enzyme in the survival and proliferation of B-cells. This drug has been gaining significant attention for its efficacy in treating various B-cell malignancies, including chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL)[3][4][5].
Clinical Trials Update
COVID-19 Related Trials
In a Phase 2 clinical trial, zanubrutinib was tested in patients hospitalized with COVID-19-related pulmonary distress. However, the trial did not meet its co-primary efficacy endpoints of respiratory failure-free survival or reduction in days on oxygen compared to placebo. Despite this, no new safety signals were identified for zanubrutinib[1].
CLL and SLL Trials
The FDA approval of zanubrutinib for CLL and small lymphocytic lymphoma (SLL) was based on two significant clinical trials: SEQUOIA and ALPINE.
-
SEQUOIA Trial: This trial evaluated zanubrutinib as a first-line treatment for CLL. Patients receiving zanubrutinib showed a longer time without cancer worsening compared to those receiving rituximab plus bendamustine. The trial also included a non-randomized cohort of patients with a 17p deletion, a molecular alteration associated with poor prognosis, where zanubrutinib demonstrated an overall response rate of 88%[4][5].
-
ALPINE Trial: In this trial, zanubrutinib was compared to ibrutinib (Imbruvica) as a second-line treatment for CLL. Zanubrutinib showed superior efficacy with fewer side effects. At 2 years, more than 78% of patients on zanubrutinib were alive with no cancer progression, compared to 66% on ibrutinib. Zanubrutinib was particularly effective in patients with genetic mutations indicating a poorer prognosis[4][5].
Mechanism of Action and Safety Profile
Zanubrutinib is a second-generation BTK inhibitor designed to address the shortcomings of first-generation inhibitors like ibrutinib. It binds BTK proteins with greater precision, remains bound for longer, and maintains high concentrations in the body during treatment. This results in a favorable side effect profile compared to other BTK inhibitors, making it a safer treatment option for patients[4][5].
