Background

Zanubrutinib is a novel Bruton's tyrosine kinase (BTK) inhibitor used for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.7 Mantle cell lymphoma is an aggressive mature B-cell non-Hodgkin lymphoma associated with early relapse, poor clinical outcomes, and long-term survival.5 BTK is an enzyme that plays a role in oncogenic signalling pathways, promoting the survival and proliferation of malignant B cells.6 Compared to the first-generation BTK inhibitor ibrutinib, zanubrutinib displays higher potency and selectivity for BTK with fewer off-target effects.4 Due to this enhanced selectivity towards BTK, zanubrutinib belongs to the second-generation BTK inhibitor drug group that also includes acalabrutinib, which was approved by the FDA in 2017.

Zanubrutinib was granted accelerated approval by the FDA in November 2019 based on clinical trial results that demonstrated an 84% overall response rate from zanubrutinib therapy in patients with MCL,8 which measures the proportion of patients in a trial whose tumour is entirely or partially destroyed by a drug.9 It is currently marketed under the trade name BRUKINSA™ and is available as oral capsules. In August 2021, the FDA granted accelerated approval to zanubrutinib for the treatment of adults with Waldenström’s macroglobulinemia.11 This indication is valid in the US, Europe, and Canada.12 In September 2021, zanubrutinib was granted another accelerated approval for the treatment of relapsed or refractory marginal zone lymphoma who have received at least one anti-CD20-based regimen.10 In October 2022, the EMA's Committee for Medicinal Products for Human Use (CHMP) recommended zanubrutinib be granted marketing authorization for the treatment of chronic lymphocytic leukemia.14

Pharmacodynamics

Zanubrutinib is an immunomodulating agent that decreases the survival of malignant B cells. It inhibits BTK by binding to its active site. It works to inhibit the proliferation and survival of malignant B cells to reduce the tumour size in mantle cell lymphoma.7

Mechanism of action

Bruton's tyrosine kinase (BTK) is a non-receptor kinase and a signalling molecule for the B cell receptors expressed on the peripheral B cell surface.6 The BCR signalling pathway plays a crucial role in normal B-cell development but also the proliferation and survival of malignant B cells in many B cell malignancies, including mantle-cell lymphoma (MCL).6,4 Once activated by upstream Src-family kinases, BTK phosphorylates phospholipase-Cγ (PLCγ), leading to Ca2+ mobilization and activation of NF-κB and MAP kinase pathways. These downstream cascades promote the expression of genes involved in B cell proliferation and survival.2 The BCR signalling pathway also induces the anti-apoptotic protein Bcl-xL and regulates the integrin α4β1 (VLA-4)-mediated adhesion of B cells to vascular cell adhesion molecule-1 (VCAM-1) and fibronectin via BTK. Apart from the direct downstream signal transduction pathway of B cells, BTK is also involved in chemokine receptor, Toll-like receptor (TLR) and Fc receptor signalling pathways.6

Zanubrutinib inhibits BTK by forming a covalent bond with cysteine 481 residue in the adenosine triphosphate (ATP)–binding pocket of BTK, which is the enzyme's active site. This binding specificity is commonly seen with other BTK inhibitors. Due to this binding profile, zanubrutinib may also bind with varying affinities to related and unrelated ATP-binding kinases that possess a cysteine residue at this position.4 By blocking the BCR signalling pathway, zanubrutinib inhibits the proliferation, trafficking, chemotaxis, and adhesion of malignant B cells, ultimately leading to reduced tumour size.7 Zanubrutinib was also shown to downregulate programmed death-ligand 1 (PD-1) expression and cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) on CD4+ T cells.1

General Function
Non-receptor tyrosine kinase that plays central but diverse modulatory roles in various signaling processes involved in the regulation of actin reorganization, cell migration, cell proliferation and survival, cell adhesion, and apoptosis. Participates in signal transduction stimulated by growth factor receptors, cytokine receptors, G-protein coupled receptors, antigen receptors and integrins. Induces tyrosine phosphorylation of BCAR1 in response to integrin regulation. Activation of BMX by integrins is mediated by PTK2/FAK1, a key mediator of integrin signaling events leading to the regulation of actin cytoskeleton and cell motility. Plays a critical role in TNF-induced angiogenesis, and implicated in the signaling of TEK and FLT1 receptors, 2 important receptor families essential for angiogenesis. Required for the phosphorylation and activation of STAT3, a transcription factor involved in cell differentiation. Also involved in interleukin-6 (IL6) induced differentiation. Plays also a role in programming adaptive cytoprotection against extracellular stress in different cell systems, salivary epithelial cells, brain endothelial cells, and dermal fibroblasts. May be involved in regulation of endocytosis through its interaction with an endosomal protein RUFY1. May also play a role in the growth and differentiation of hematopoietic cells; as well as in signal transduction in endocardial and arterial endothelial cells.

General Function
Non-receptor tyrosine kinase involved in B-lymphocyte development, differentiation and signaling. B-cell receptor (BCR) signaling requires a tight regulation of several protein tyrosine kinases and phosphatases, and associated coreceptors. Binding of antigen to the B-cell antigen receptor (BCR) triggers signaling that ultimately leads to B-cell activation. Signaling through BLK plays an important role in transmitting signals through surface immunoglobulins and supports the pro-B to pre-B transition, as well as the signaling for growth arrest and apoptosis downstream of B-cell receptor. Specifically binds and phosphorylates CD79A at 'Tyr-188'and 'Tyr-199', as well as CD79B at 'Tyr-196' and 'Tyr-207'. Phosphorylates also the immunoglobulin G receptors FCGR2A, FCGR2B and FCGR2C. With FYN and LYN, plays an essential role in pre-B-cell receptor (pre-BCR)-mediated NF-kappa-B activation. Contributes also to BTK activation by indirectly stimulating BTK intramolecular autophosphorylation. In pancreatic islets, acts as a modulator of beta-cells function through the up-regulation of PDX1 and NKX6-1 and consequent stimulation of insulin secretion in response to glucose.

General Function
Non-receptor tyrosine kinase that plays a redundant role with ITK in regulation of the adaptive immune response. Regulates the development, function and differentiation of conventional T-cells and nonconventional NKT-cells. When antigen presenting cells (APC) activate T-cell receptor (TCR), a series of phosphorylation lead to the recruitment of TXK to the cell membrane, where it is phosphorylated at Tyr-420. Phosphorylation leads to TXK full activation. Contributes also to signaling from many receptors and participates in multiple downstream pathways, including regulation of the actin cytoskeleton. Like ITK, can phosphorylate PLCG1, leading to its localization in lipid rafts and activation, followed by subsequent cleavage of its substrates. In turn, the endoplasmic reticulum releases calcium in the cytoplasm and the nuclear activator of activated T-cells (NFAT) translocates into the nucleus to perform its transcriptional duty. With PARP1 and EEF1A1, TXK forms a complex that acts as a T-helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFNG to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production. Phosphorylates both PARP1 and EEF1A1. Phosphorylates also key sites in LCP2 leading to the up-regulation of Th1 preferred cytokine IL-2. Phosphorylates 'Tyr-201' of CTLA4 which leads to the association of PI-3 kinase with the CTLA4 receptor.
