Abstract
Targeting B-cell receptor signalling using Bruton tyrosine kinase (BTK) inhibitors (BTKis) has become a highly successful treatment modality for B-cell malignancies, especially for chronic lymphocytic leukaemia. However, long-term administration of BTKis can be complicated by adverse on- and/or off-target effects in particular cell types. BTK is widely expressed in cells of haematopoietic origin, which are pivotal components of the tumour microenvironment. BTKis, thus, show broad immunomodulatory effects on various non-B immune cell subsets by inhibiting specific immune receptors, including T-cell receptor and Toll-like receptors. Furthermore, due to the off-target inhibition of other kinases, such as IL-2-inducible T-cell kinase, epidermal growth factor receptor, and the TEC and SRC family kinases, BTKis have additional distinct effects on T cells, natural killer cells, platelets, cardiomyocytes, and other cell types. Such mechanisms of action might contribute to the exceptionally high clinical efficacy as well as the unique profiles of adverse effects, including infections, bleeding, and atrial fibrillation, observed during BTKi administration. However, the immune defects and related infections caused by BTKis have not received sufficient attention in clinical studies till date. The broad involvement of BTK in immunological pathways provides a rationale to combine BTKis with specific immunotherapies, such as immune checkpoint inhibitor or chimeric antigen receptor-T-cell therapy, for the treatment of relapsed or refractory diseases. This review discusses and summarises the above-mentioned issues as a reference for clinicians and researchers.

Pooled safety analysis of zanubrutinib monotherapy in patients with B-cell malignancies. Blood Adv 2022; 6:1296-1308. [PMID: 34724705 PMCID: PMC8864647 DOI: 10.1182/bloodadvances.2021005621] [Citation(s) in RCA: 43] [Impact Index Per Article: 21.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 10/04/2021] [Indexed: 11/20/2022] Open
Abstract
Zanubrutinib is a selective Bruton tyrosine kinase (BTK) inhibitor evaluated in multiple B-cell malignancy studies. We constructed a pooled safety analysis to better understand zanubrutinib-associated treatment-emergent adverse events (TEAEs) and identify treatment-limiting toxicities. Data were pooled from 6 studies (N = 779). Assessments included type, incidence, severity, and outcome of TEAEs. Median age was 65 years; 20% were ≥75 years old. Most patients had Waldenström macroglobulinemia (33%), chronic lymphocytic leukemia/small lymphocytic lymphoma (29%), or mantle-cell lymphoma (19%). Median treatment duration was 26 months (range, 0.1-65); 16% of patients were treated for ≥3 years. Common nonhematologic TEAEs were upper respiratory tract infection (URI, 39%), rash (27%), bruising (25%), musculoskeletal pain (24%), diarrhea (23%), cough (21%), pneumonia (21%), urinary tract infection (UTI), and fatigue (15% each). Most common grade ≥3 TEAEs were pneumonia (11%), hypertension (5%), URI, UTI, sepsis, diarrhea, and musculoskeletal pain (2% each). Atrial fibrillation and major hemorrhage occurred in 3% and 4% of patients, respectively. Atrial fibrillation, hypertension, and diarrhea occurred at lower rates than those reported historically for ibrutinib. Grade ≥3 adverse events included neutropenia (23%), thrombocytopenia (8%), and anemia (8%). Serious TEAEs included pneumonia (11%), sepsis (2%), and pyrexia (2%).Treatment discontinuations and dose reductions for adverse events occurred in 10% and 8% of patients, respectively. Thirty-nine patients (4%) had fatal TEAEs, including pneumonia (n = 9), sepsis (n = 4), unspecified cause (n = 4), and multiple organ dysfunction syndrome (n = 5). This analysis demonstrates that zanubrutinib is generally well tolerated with a safety profile consistent with known BTK inhibitor toxicities; these were manageable and mostly reversible.

Abstract
The use of targeted biologic therapies for hematological malignancies has greatly expanded in recent years. These agents act upon specific molecular pathways in order to target malignant cells but frequently have broader effects involving both innate and adaptive immunity. Patients with hematological malignancies have unique risk factors for infection, including immune dysregulation related to their underlying disease and sequelae of prior treatment regimens. Determining the individual risk of infection related to any novel agent is challenging in this setting. Invasive fungal infections (IFIs) represent one of the most morbid infectious complications observed in hematological malignancy. In recent years, growing evidence suggests that certain small molecule inhibitors, such as BTK inhibitors and PI3K inhibitors, may cause an increased risk of IFI in certain patients. It is imperative to better understand the impact that novel targeted therapies might have on the development of IFIs in this high-risk patient population.

Abstract
ABSTRACT Over the last 2 decades, treatment of chronic lymphocytic leukemia (CLL) therapy has drastically changed, resulting in greatly improved survival and treatment tolerance with current targeted therapies. First, the transition from chemotherapy (alkylating agents, nucleoside analogs) to chemoimmunotherapy with the addition of anti-CD20 antibodies resulted in deeper and more complete remissions, with an improvement in progression-free and overall survival. Over the last few years, chemoimmunotherapy has gradually been replaced by new targeted agents, based on further improvement in survival, especially in patients with high-risk CLL, and fewer adverse effects, that is, a lack of myelosuppression and lack of DNA damage and associated risk of secondary acute myeloid leukemia/myelodysplastic syndrome. The most active targeted treatments for CLL patients are the kinase inhibitors, which inhibit signaling of surface receptors, especially the B-cell antigen receptor, and the BCL-2 antagonist venetoclax. Among the kinase inhibitors, Bruton tyrosine kinase inhibitors are highly effective and generally well-tolerated and induce durable responses in the vast majority of patients. PI3 kinase inhibitors are alternatives for patients with intolerance to Bruton tyrosine kinase inhibitors. This review discusses the rationale for the transition from chemotherapy-based treatment to the novel agents, the activity, adverse effects, sequencing, and combinations of the novel agents and provides an outlook into future CLL therapy for the next decade.

Abstract
Higher risks of infection are associated with some targeted drugs used to treat solid organ and hematological malignancies, and an individual patient’s risk of infection is strongly influenced by underlying diseases and concomitant or prior treatments. This review focuses on risk levels and specific suggestions for management, analyzing groups of agents associated with a significant effect on the risk of infection. Due to limited clinical experience and ongoing advances in these therapies, recommendations may be revised in the near future. Bruton tyrosine kinase (BTK) inhibitors are associated with a higher rate of infections, including invasive fungal infection, especially in the first months of treatment and in patients with advanced, pretreated disease. Phosphatidylinositol 3-kinase (PI3K) inhibitors are associated with an increased risk of Pneumocystis pneumonia and cytomegalovirus (CMV) reactivation. Venetoclax is associated with cytopenias, respiratory infections, and fever and neutropenia. Janus kinase (JAK) inhibitors may predispose patients to opportunistic and fungal infections; need for prophylaxis should be assessed on an individual basis. Mammalian target of rapamycin (mTOR) inhibitors have been linked to a higher risk of general and opportunistic infections. Breakpoint cluster region-Abelson (BCR-ABL) inhibitors are associated with neutropenia, especially over the first months of treatment. Anti-CD20 agents may cause defects in the adaptative immune response, hypogammaglobulinemia, neutropenia, and hepatitis B reactivation. Alemtuzumab is associated with profound and long-lasting immunosuppression; screening is recommended for latent infections and prevention strategies against CMV, herpesvirus, and Pneumocystis infections. Checkpoint inhibitors (CIs) may cause immune-related adverse events for which prolonged treatment with corticosteroids is needed: prophylaxis against Pneumocystis is recommended.

Abstract
Inhibiting the activity of Bruton tyrosine kinase (BTK) prevents the activation of the B-cell receptor (BCR) signaling pathway, which in turn prevents both B-cell activation and BTK-mediated activation of downstream survival pathways. Acalabrutinib is an orally available, highly selective, next-generation inhibitor of BTK. Based on the results of two key phase 3 trials (ELEVATE-TN in patients with previously untreated chronic lymphocytic leukemia [CLL] and ASCEND in patients with relapsed or refractory CLL), which demonstrated superior progression-free survival while maintaining favorable tolerability, acalabrutinib was granted US Food and Drug Administration (FDA) approval in 2019 for the treatment of patients with CLL. Acalabrutinib appears to offer similar efficacy but a significantly improved tolerability profile to first-generation agents. Acalabrutinib is a good candidate to combine with other anti-cancer therapies, including B-cell lymphoma 2 inhibitors and monoclonal antibodies, a factor that may help to further improve clinical outcomes in CLL.
