Abstract
The treatment landscape for CLL has undergone a profound transformation with the advent of targeted agents (TAs) like Bruton's Tyrosine Kinase inhibitors (BTKis) and BCL-2 inhibitors (BCL-2is). These agents target crucial cellular pathways in CLL, offering superior efficacy over traditional chemo-immunotherapy, which has led to improved progression-free and overall survival rates. This advancement promises enhanced disease control and potentially normal life expectancy for many patients. However, the journey is not without challenges, as these TAs are associated with a range of adverse events (AEs) that can impact treatment efficacy and patient quality of life. This review focuses on detailing the various AEs related to TA management in CLL, evaluating their frequency and clinical impact. The aim is to present a comprehensive guide to the effective management of these AEs, ensuring optimal tolerability and efficacy of TAs. By reviewing the existing literature and consolidating findings, we provide insights into AE management, which is crucial for maximizing patient outcomes in CLL therapy.

Incidence of cardiovascular and bleeding events and reasons for discontinuation in patients with chronic lymphocytic leukemia treated with ibrutinib-A retrospective analysis on consecutive patients from a well-defined region. Eur J Haematol 2023; 111:748-756. [PMID: 37565648 DOI: 10.1111/ejh.14072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 07/20/2023] [Accepted: 07/21/2023] [Indexed: 08/12/2023]
Abstract
OBJECTIVE Ibrutinib treatment is associated with cardiovascular side effects, in particular atrial fibrillation (AF) and hypertension, as well as increased risk of bleeding. Here, we aimed at describing the incidence of these events during long-term follow-up in patients with chronic lymphocytic leukemia treated outside clinical trials as well as identifying clinical factors predictive of developing AF. Additionally, other reasons for treatment withdrawal were analyzed. METHODS The study was retrospective, data were collected from medical records. RESULTS A total of 134 patients were identified. Median follow-up was 32 months (range 3-103) and median duration of ibrutinib treatment was 26 months (range 1-103). Of 110 patients with no prior history of AF, 24.5% were diagnosed during treatment. Newly diagnosed or worsening of pre-existing hypertension occurred in 15.7%. Sixty-six % of the patients experienced bleeding events, of which 7.5% grade 3-4. Treatment discontinuation and dose reduction occurred in 68% and 47% of the patients, respectively, mostly due to toxicity. CONCLUSIONS The incidence of AF was high and at a median follow-up of 2.5 years, two-thirds of the patients discontinued treatment mostly due to bleeding and infections. Treatment-related toxicity of any grade should be regarded as a concern of prolonged ibrutinib therapy.

Abstract
Targeted therapy with Bruton tyrosine kinase (BTK) inhibitors have revolutionized the treatment of patients with various B-cell malignancies. BTK inhibitors such as ibrutinib, zanubrutinib, orelabrutinib, and acalabrutinib have shown good clinical efficacy and better safety profiles than those of traditional chemotherapy and chemoimmunotherapy regimens. Multiple studies on new BTK inhibitors are ongoing, which may provide more therapeutic options for the treatment of B-cell malignancies. Considering the unmet need of evidence on BTK inhibitors in all clinical settings and to standardize the use of BTK inhibitors available in mainland China, Taiwan, Hong Kong, and Macau regions, this consensus has been formulated for the treatment of various B-cell malignancies based on the clinical practice and available evidences on the use of BTK inhibitors. The recommendations of this consensus will provide guidance to physicians and clinical researchers on the effective treatment of B-cell malignancies with BTK inhibitors.

Abstract
The traditional paradigm of oncologic treatment centered on cytotoxic chemotherapy has undergone tremendous advancement during the last 15 yr with the advent of immunotherapy and targeted cancer therapies. These agents, including small molecule inhibitors, monoclonal antibodies, and immune-checkpoint inhibitors, are highly specific to individual tumor characteristics and can prevent cell growth and tumorigenesis by inhibiting specific molecular targets or single oncogenes. While generally better tolerated than traditional chemotherapy, these therapies are associated with unique constellations of adverse effects. Of particular importance in the perioperative and periprocedural settings are hematologic abnormalities, particularly antiplatelet effects with increased risk of bleeding, and implications for wound healing. This narrative review discusses targeted cancer therapies and provides recommendations for physicians managing these patients' care as it relates to procedural or surgical interventions.

Abstract
Since their invention in the early 2000s, tyrosine kinase inhibitors (TKIs) have gained prominence as the most effective pathway-directed anti-cancer agents. TKIs have shown significant utility in the treatment of multiple hematological malignancies and solid tumors, including chronic myelogenous leukemia, non-small cell lung cancers, gastrointestinal stromal tumors, and HER2-positive breast cancers. Given their widespread applications, an increasing frequency of TKI-induced adverse effects has been reported. Although TKIs are known to affect multiple organs in the body including the lungs, liver, gastrointestinal tract, kidneys, thyroid, blood, and skin, cardiac involvement accounts for some of the most serious complications. The most frequently reported cardiovascular side effects range from hypertension, atrial fibrillation, reduced cardiac function, and heart failure to sudden death. The potential mechanisms of these side effects are unclear, leading to critical knowledge gaps in the development of effective therapy and treatment guidelines. There are limited data to infer the best clinical approaches for the early detection and therapeutic modulation of TKI-induced side effects, and universal consensus regarding various management guidelines is yet to be reached. In this state-of-the-art review, we examine multiple pre-clinical and clinical studies and curate evidence on the pathophysiology, mechanisms, and clinical management of these adverse reactions. We expect that this review will provide researchers and allied healthcare providers with the most up-to-date information on the pathophysiology, natural history, risk stratification, and management of emerging TKI-induced side effects in cancer patients.

Cancers (Basel) 2023; 15:cancers15071996. [PMID: 37046657 PMCID: PMC10093473 DOI: 10.3390/cancers15071996] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 03/23/2023] [Accepted: 03/23/2023] [Indexed: 03/29/2023] Open
Abstract
The effectiveness and safety of combination treatments such as chemoimmunotherapies in chronic lymphocytic leukemia and small lymphocytic lymphoma (CLL/SLL) remain controversial. Bruton tyrosine kinase inhibitors (BTKis) are an effective therapy for CLL/SLL patients. This meta-analysis aimed to compare the efficacy and safety of BTKis versus combination therapy in CLL/SLL patients. We searched the PubMed, Cochrane, Medline, and Embase databases through February 2023 for relevant randomized controlled trials (RCTs). Four RCTs (including 1510 patients) were found and met the inclusion criteria. Progression-free survival (PFS) was significantly improved with BTKis when compared to the combination therapy (hazard ratio (HR), 0.30; 95% confidence interval (CI), 0.22–0.40), while a pooled analysis of overall survival did not favor single-agent BTKis over the combination therapy (HR, 0.87; 95% CI, 0.67–1.15). We observed consistent benefits for PFS among patients with high-risk disease characteristics. Although there was no difference in complete response between the two arms (risk ratio (RR), 0.54; 95% CI, 0.20–1.46), BTKi use was related to a better overall response rate (RR, 1.10; 95% CI, 1.04–1.16). The risk of grade ≥3 adverse events (AEs) was comparable between the two arms (RR, 0.82; 95% CI, 0.55–1.23). However, the risk of grade ≥3 AEs was significantly lower in the second-generation BTKi group than in the combination therapy group (RR, 0.73; 95% CI, 0.54–0.98). Overall, BTKis have superior efficacy compared to the combination regimens in patients with untreated or treated CLL/SLL without excess toxicity. Further studies are needed to confirm these results and determine the optimal therapy for managing patients with CLL/SLL.

Structural Complementarity of Bruton’s Tyrosine Kinase and Its Inhibitors for Implication in B-Cell Malignancies and Autoimmune Diseases. Pharmaceuticals (Basel) 2023; 16:ph16030400. [PMID: 36986499 PMCID: PMC10051736 DOI: 10.3390/ph16030400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 02/08/2023] [Accepted: 02/24/2023] [Indexed: 03/09/2023] Open
Abstract
Bruton’s tyrosine kinase (BTK) is a critical component in B-cell receptor (BCR) signaling and is also expressed in haematogenic and innate immune cells. Inhibition of BTK hyperactivity is implicated in B-cell malignancies and autoimmune diseases. This review derives the structural complementarity of the BTK-kinase domain and its inhibitors from recent three-dimensional structures of inhibitor-bound BTK in the protein data bank (PDB). Additionally, this review analyzes BTK-mediated effector responses of B-cell development and antibody production. Covalent inhibitors contain an α, β-unsaturated carbonyl moiety that forms a covalent bond with Cys481, stabilizing αC-helix in inactive-out conformation which inhibits Tyr551 autophosphorylation. Asn484, located two carbons far from Cys481, influences the stability of the BTK-transition complex. Non-covalent inhibitors engage the BTK-kinase domain through an induced-fit mechanism independent of Cys481 interaction and bind to Tyr551 in the activation kink resulting in H3 cleft, determining BTK selectivity. Covalent and non-covalent binding to the kinase domain of BTK shall induce conformational changes in other domains; therefore, investigating the whole-length BTK conformation is necessary to comprehend BTK’s autophosphorylation inhibition. Knowledge about the structural complementarity of BTK and its inhibitors supports the optimization of existing drugs and the discovery of drugs for implication in B-cell malignancies and autoimmune diseases.

Abstract
Acute myeloid leukemia (AML) is the most common and aggressive form of acute leukemia, with a 5-year survival rate of just 24%. Over a third of all AML patients harbor activating mutations in kinases, such as the receptor tyrosine kinases FLT3 (receptor-type tyrosine-protein kinase FLT3) and KIT (mast/stem cell growth factor receptor kit). FLT3 and KIT mutations are associated with poor clinical outcomes and lower remission rates in response to standard-of-care chemotherapy. We have recently identified that the core kinase of the non-homologous end joining DNA repair pathway, DNA-PK (DNA-dependent protein kinase), is activated downstream of FLT3; and targeting DNA-PK sensitized FLT3-mutant AML cells to standard-of-care therapies. Herein, we investigated DNA-PK as a possible therapeutic vulnerability in KIT mutant AML, using isogenic FDC-P1 mouse myeloid progenitor cell lines transduced with oncogenic mutant KIT (V560G and D816V) or vector control. Targeted quantitative phosphoproteomic profiling identified phosphorylation of DNA-PK in the T2599/T2605/S2608/S2610 cluster in KIT mutant cells, indicative of DNA-PK activation. Accordingly, proliferation assays revealed that KIT mutant FDC-P1 cells were more sensitive to the DNA-PK inhibitors M3814 or NU7441, compared with empty vector controls. DNA-PK inhibition combined with inhibition of KIT signaling using the kinase inhibitors dasatinib or ibrutinib, or the protein phosphatase 2A activators FTY720 or AAL(S), led to synergistic cell death. Global phosphoproteomic analysis of KIT-D816V cells revealed that dasatinib and M3814 single-agent treatments inhibited extracellular signal-regulated kinase and AKT (RAC-alpha serine/threonine-protein kinase)/MTOR (serine/threonine-protein kinase mTOR) activity, with greater inhibition of both pathways when used in combination. Combined dasatinib and M3814 treatment also synergistically inhibited phosphorylation of the transcriptional regulators MYC and MYB. This study provides insight into the oncogenic pathways regulated by DNA-PK beyond its canonical role in DNA repair and demonstrates that DNA-PK is a promising therapeutic target for KIT mutant cancers.

Abstract
Waldenström macroglobulinemia (WM) is a rare B-cell Non-Hodgkin Lymphoma. There are only few prospective randomized clinical trials to guide treatment recommendations and there is no international consensus on a preferred first line treatment approach. In the recently revised Dutch guideline for WM, we describe recommendations for practice based as much as possible on the known data. Here, we summarize the considerations for first-line treatment based on these Dutch guidelines. Available evidence is summarized, including efficacy and toxicity data. Combinations of Rituximab with chemotherapy, proteasome inhibition or BTK-inhibition are all valid first line treatment options. The Dutch WM working group considers Dexamethasone/Rituximab/Cylofosfamide (DRC) a suitable first-line treatment for many WM patients, given the efficacy, the relatively mild toxicity profile and the extensive experience with this regimen. However, the long-term toxicities of DRC are unclear and need further clarification. Other regimens such as R-bendamustine, R-Bortezomib-dexamethason are also effective options, however with specific toxicities. BTK-inhibitors are not a preferred option in first line for most patients in the Dutch WM guidelines because of the need for longterm treatment and toxicities. Based on patient preferences research, future clinical trials should focus on effective fixed-duration regimens with non-cytotoxic therapies that have a favorable toxicity profile. Further development of (combinations with) BCL-2 inhibititors, novel proteasome inhibitors and BTK-inhibition could be interesting. In addition T-cell-directed treatments including bispecific antibodies as a monotherapy or combined with other novel agents deserve further study in WM.

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.

Abstract
Ibrutinib is the first-in-class Bruton tyrosine kinase (BTK) inhibitor that has revolutionized the treatment of B cell malignancies. Unfortunately, increased incidences of cardiotoxicity have limited its use. Despite over a decade of research, the biological mechanisms underlying ibrutinib cardiotoxicity remain unclear. In this review, we discuss the pharmacological properties of ibrutinib, the incidence and mechanisms of ibrutinib-induced cardiotoxicity, and practical management to prevent and treat this condition. We also synopsize and discuss the cardiovascular adverse effects related to other more selective BTK inhibitors, which may guide the selection of appropriate BTK inhibitors.

International Consensus Statement on the Management of Cardiovascular Risk of Bruton's Tyrosine Kinase Inhibitors in CLL. Blood Adv 2022; 6:5516-5525.

Abstract
Bruton's tyrosine kinase inhibitors (BTKis) have altered the treatment landscape for chronic lymphocytic leukemia (CLL) by offering effective and well-tolerated therapeutic options. However, since the approval of ibrutinib, concern has risen regarding the risk of cardiovascular (CV) adverse events including atrial fibrillation (AF), hypertension, and heart failure. Newer BTKis appear to have lower cardiovascular risks, but data are limited. It is important to understand the risks posed by BTKis and how those risks interact with individual patients, and we convened a panel of physicians with expertise in CLL and cardiovascular toxicities in oncology to develop evidence-based consensus recommendations for community hematologists and oncologists. Care providers should thoroughly assess a patient's cardiovascular risk level before treatment initiation including established cardiovascular diseases and risk factors and performing investigations, dependent on pre-existing diseases and risk factors, including an electrocardiogram (ECG). For patients with high CV risk, BTKi treatment is often appropriate in consultation with a multidisciplinary team (MDT), and more selective BTKis including acalabrutinib and zanubrutinib are preferred. BTKi treatment should generally be avoided in patients with a history of heart failure. Ibrutinib should be avoided in patients with a history of ventricular arrhythmias, but the risk of newer drugs is not yet known. Finally, an MDT is crucial to help manage emerging toxicities with the goal of maintaining BTKi therapy, if possible. Optimizing heart failure, arrhythmia, and hypertension control will likely improve tolerance and maintenance of BTKi therapy. However, additional studies are needed to identify the most optimal strategy for these drugs.

Abstract
Aim To evaluate the effect of cardiac monitoring on overall survival of patients with chronic lymphoid leukosis (CLL) on targeted therapy with ibrutinib.Material and methods Survival of oncological patients depends not only on the efficacy of the antitumor therapy. Cardiovascular comorbidities and emerging cardiotoxicity of the antitumor treatment can considerably impair the quality and duration of patients' life. The problem of the need for regular cardiological monitoring of oncological patients remains unsolved. A prospective 5-year study was performed that included cardiological monitoring of patients with CLL on chronic targeted therapy with ibrutinib, the side effects of which include atrial fibrillation (AF) and arterial hypertension (AH). The study included 217 patients aged 66.0 [32.0; 910.] years; 144 of them were men aged 66.0 [32.0; 91.0] years and 83 were women aged 65.0 [39.0; 83.0] years. Electrocardiography and echocardiography, evaluation of comorbidity with the Charlson's index, and evaluation of frailty with the Geriatric 8 questionnaire and the Groningen Frailty Index were performed repeatedly for all patients. In the active cardiac monitoring group (n=89), besides the standard evaluation, active medical monitoring of symptoms and general well-being, blood pressure (BP) and pulse rate, monitoring of cardioprotective drug intake and correction, if necessary, and calling patients for examination and additional evaluation were performed every week. The remaining 128 patients were evaluated repeatedly but did not maintain the remote monitoring with messengers; they constituted a standard follow-up group.Results This was a study of overall survival of patients with CLL on targeted therapy with ibrutinib depending on the cardiac monitoring program. The age of patients did not differ in the active cardiac monitoring group and the standard follow-up group (66.0 [60.0; 70.0] and 66.0 [59.0; 74.0] years, respectively). The active cardiac monitoring group contained somewhat more men than the standard follow-up group (68.8 and 53.9 %, respectively; р=0.026). At baseline, the groups did not differ in the number of pretreatment lines, frailty test results (Geriatric 8 questionnaire, Groningen Frailty Index), comorbidity (Charlson's index), and echocardiographic data. The active cardiac monitoring group contained more patients with AH (р<0.0001), with AF (р<0.0001), patients receiving anticoagulants (р<0.0001), and a comparable number of patients with ischemic heart disease. In the active cardiac monitoring group, 70 (90.9%) of 77 patients with CLL and AH achieved goal BP whereas in the standard follow-up group, 26 (39.9 %) of 66 (р<0.0001) patients achieved the BP goal, regardless of whether their elevated BP developed before or during the ibrutinib treatment. This group contained significantly more patients who required cardiac surgical intervention (coronary stenting, pacemaker implantation), 12 vs. 0 in the standard follow-up group (р=0.0004). The overall 5-year survival was significantly higher for patients of the active cardiac monitoring group, both for men (р<0.0001) and women (р<0.0001) with CLL, including patients older than 70 years (р=0.0004), CLL patients with a median pretreatment line number of 1 (р<0.0001), patients with a median chemotherapy line number of 4 (р<0.0001), and patients with genetic abnormalities (р=0.004) pretreated with fludarabine and/or anthracyclines (р<0.0001). The Cox regression analysis showed that the strongest predictor of survival was the achievement of stable goal BP in CLL patients with AH during the continuous cardiac monitoring. Despite more pronounced cardiac comorbidity, CLL patients on the active cardiac monitoring group showed a longer survival than patients on the standard follow-up. Thus, mean survival time of deceased CLL patients who had been on the cardiac monitoring was 36.1 months vs. 17.5 months (р<0.0001) for patients who had been on the standard follow-up.Conclusion The study has demonstrated the prognostic significance of continuous participation of a cardiologist in managing onco-hematological patients. CLL patients on the active cardiac monitoring, the regular pattern of which was provided by the remote control, had a significantly higher overall survival compared to patients who visited a cardiologist periodically. A significant predomination of patients with CLL and AH who achieved stable goal BP, continuous monitoring of anticoagulant dosing in patients with AF in that group, and early detection and correction of cardiovascular complications can explain the highly significant difference in the 5-year survival between CLL patients on chronic targeted ibrutinib treatment with different cardiac monitoring programs (р<0.0001). The active cardiac monitoring with remote control allows achievement of a higher 5-year overall survival of CLL patients receiving ibrutinib (p<0.0001).

Abstract
The advent of novel targeted therapies, including B-cell receptor (BCR) pathway and B-cell lymphoma 2 (BCL2) inhibitors, has substantially changed the treatment paradigm for chronic lymphocytic leukemia (CLL). Although targeted therapies have improved outcomes compared to traditional chemoimmunotherapy in the front-line and relapsed or refractory settings, they are associated with resistance mutations and suboptimal outcomes in certain high-risk patients. Additionally, targeted therapies are associated with drug interactions and unique adverse effect profiles which can be challenging for patients and clinicians to manage. Ongoing studies continue to address questions regarding optimal sequencing of therapies, the role of treatment combinations, and the efficacy of next-generation novel agents. This review provides a comprehensive overview regarding the clinical management of targeted therapies for CLL and applies current literature to clinical practice.

Abstract
The use of Bruton's tyrosine kinase (BTK) inhibitors has changed the management and clinical history of patients with chronic lymphocytic leukemia (CLL). BTK is a critical molecule that interconnects B-cell antigen receptor (BCR) signaling. BTKis are classified into two categories: irreversible (covalent) inhibitors and reversible (non-covalent) inhibitors. Ibrutinib was the first irreversible BTK inhibitor approved by the U.S. Food and Drug Administration in 2013 as a breakthrough therapy in CLL patients. Subsequently, several studies have evaluated the efficacy and safety of new agents with reduced toxicity when compared with ibrutinib. Two other irreversible, second-generation BTK inhibitors, acalabrutinib and zanubrutinib, were developed to reduce ibrutinib-mediated adverse effects. Additionally, new reversible BTK inhibitors are currently under development in early-phase studies to improve their activity and to diminish adverse effects. This review summarizes the pharmacology, clinical efficacy, safety, dosing, and drug-drug interactions associated with the treatment of CLL with BTK inhibitors and examines their further implications.

Abstract
Background Ibrutinib and acalabrutinib are Bruton tyrosine kinase inhibitors used in the treatment of B‐cell lymphoproliferative disorders. Ibrutinib is associated with new‐onset atrial fibrillation. Cases of sinus bradycardia and sinus arrest have also been reported following ibrutinib treatment. Conversely, acalabrutinib is less arrhythmogenic. The basis for these different effects is unclear. Methods and Results The effects of ibrutinib and acalabrutinib on atrial electrophysiology were investigated in anesthetized mice using intracardiac electrophysiology, in isolated atrial preparations using high‐resolution optical mapping, and in isolated atrial and sinoatrial node (SAN) myocytes using patch‐clamping. Acute delivery of acalabrutinib did not affect atrial fibrillation susceptibility or other measures of atrial electrophysiology in mice in vivo. Optical mapping demonstrates that ibrutinib dose‐dependently impaired atrial and SAN conduction and slowed beating rate. Acalabrutinib had no effect on atrial and SAN conduction or beating rate. In isolated atrial myocytes, ibrutinib reduced action potential upstroke velocity and Na+ current. In contrast, acalabrutinib had no effects on atrial myocyte upstroke velocity or Na+ current. Both drugs increased action potential duration, but these effects were smaller for acalabrutinib compared with ibrutinib and occurred by different mechanisms. In SAN myocytes, ibrutinib impaired spontaneous action potential firing by inhibiting the delayed rectifier K+ current, while acalabrutinib had no effects on SAN myocyte action potential firing. Conclusions Ibrutinib and acalabrutinib have distinct effects on atrial electrophysiology and ion channel function that provide insight into the basis for increased atrial fibrillation susceptibility and SAN dysfunction with ibrutinib, but not with acalabrutinib.

Abstract
OBJECTIVES Ibrutinib, a potent inhibitor of the Bruton tyrosine kinase, has revolutionized the treatment of many B-cell malignancies. Ibrutinib has an established favorable toxicity profile with up to 8 years of experience in clinical trials; however, despite ibrutinib's favorable toxicity profile, dose reductions and treatment discontinuations are becoming more evident in clinical practice, particularly in the setting of specific clinical contexts and patient characteristics. This manuscript is set to provide practical recommendations on the management of patients treated with this agent in daily practice. METHODS A group of multidisciplinary experts from Portugal met to discuss and highlight practical recommendations, supported on both literature and clinical insights, for the management of the treatment with ibrutinib. RESULTS/DISCUSSION Handling of both toxicities and drug-drug interactions during ibrutinib treatment poses several challenges to healthcare providers and can benefit from a multidisciplinary approach. The involvement of specialties, such as cardiology, infectiology and pharmacology, can bring an added value to patient care, not only in anticipating/managing safety issues and dose adjustments but also in enhancing adherence to treatment, ultimately improving the risk/benefit balance. CONCLUSION By involving a multidisciplinary group of experts, this work provides a set of key recommendations to optimize care and outcomes for ibrutinib-treated patients. Despite not being a fully comprehensive review on the topic, it is intended as a framework to hematologists and other healthcare professionals who manage these patients in their daily clinical practice.

Abstract
BACKGROUND The incidence of atrial fibrillation (AF) in patients with chronic lymphocytic leukemia (CLL) has been on the rise. However, the excess burden added by AF to the morbidity and mortality of CLL patients especially in the hospitalized setting is undetermined. METHODS The National Inpatient Sample (NIS) database was accessed to gather data of hospitalized CLL patients with AF from 2009 to 2018. Propensity-score matching (PSM) and logistic regression model were performed to control for baseline patient factors to match 7265 CLL patient admissions with AF and 7265 CLL patient admissions without AF. The primary outcome was all-cause mortality (ACM), while the secondary outcomes included acute coronary syndrome (ACS), acute myocardial infarction (AMI), and the need for percutaneous coronary intervention (PCI), acute heart failure (AHF), acute hypoxic respiratory failure (AHRF), cardiac arrest (CA), cardiogenic shock (CS), stroke, and the total cost of hospitalization. RESULTS CLL patients with AF had a higher rate of ACM (6.06% vs 4.47%; odds ratio [OR] 1.39, 95% confidence interval [CI] 1.19-1.61; P =< .001). All other secondary outcomes including ACS, AMI, PCI, AHRF, CA, CS, and stroke were observed at a significantly higher rate in the AF group as well. The median total hospital cost was also higher in the AF group ($9097 vs. $7646; P value < .0001) CONCLUSION: CLL patients with AF are at a significantly increased risk of all-cause mortality, cardiac-related mortality, and stroke. For this population, a multidisciplinary approach should be orchestrated for better management and outcomes.

Cerebral aspergillosis and facial acneiform lesions following initiation of ibrutinib in a patient with chronic lymphocytic leukemia. IDCases 2021; 26:e01263. [PMID: 34504767 PMCID: PMC8416634 DOI: 10.1016/j.idcr.2021.e01263] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2020] [Revised: 08/26/2021] [Accepted: 08/30/2021] [Indexed: 11/20/2022] Open
Abstract
A case of a 67-year-old male with CLL, presented with prolonged pancytopenia after his first cycle of fludarabine, cyclophosphamide, and rituximab (FCR) chemotherapy. He was then treated with ibrutinib oral monotherapy. Shortly after ibrutinib treatment initiation, he developed a brain abscess and pulmonary disease as a part of an invasive aspergillosis. The patient improved after brain abscess drainage and the anti-fungal therapy voriconazole. Upon resuming ibrutinib four months after his hospitalization, he developed extensive acneiform facial lesions. This case is the first to report on the development of two separate complications in one patient related to ibrutinib, namely, Aspergillus infection, and severe acneiform skin lesions.

Abstract
Venous thromboembolism (VTE) is a common complication occurring in 5-10% of patients with lymphoma. As the complexity of lymphoma management has increased with novel therapies, so too has the treatment of VTE. Therapeutic options for the treatment of cancer-associated VTE have expanded from only warfarin and low-molecular-weight heparins (LMWHs) to include the direct oral anticoagulants (DOACs) apixaban, edoxaban and rivaroxaban. There have been no head-to-head trials comparing different DOACs in this setting and randomized trials comparing a DOAC with LMWH dalteparin differ in trial design and results. Drug-drug interactions, drug-specific side effects and patient selection are important considerations when prescribing anticoagulant therapy. In all patients, the relative risks of thrombosis and bleeding, the availability of the anticoagulant, and the life expectancy of the patient are vital elements in selecting the most appropriate anticoagulant (which can vary over time) for the individual patient. We describe the intricacies and challenges of treating thrombotic complications in patients with lymphoma with an emphasis on evidence and guideline-based care.

Abstract
Ibrutinib is a novel drug used in haematological malignancies. Its use is associated with an increased risk of atrial fibrillation (AF), which, in turn, exposes patients to embolic risk, including stroke. Reducing this risk requires anticoagulant therapy which is a matter of concern in the context of the increased bleeding risk of patients with haematological malignancies. In this context the presence of thrombocytopenia related to haematological disorder, ibrutinib-anticoagulants and ibrutinib-platelets interactions contribute to the amplification of the problem. The correct assessment of the thrombosis vs. haemorrhage balance represents a significant challenge for the clinician. In this paper we discuss practical issues related to anticoagulation in patients treated with ibrutinib and incident AF.

Abstract
INTRODUCTION Outcomes in chronic lymphocytic leukemia (CLL) have been dramatically improved with the addition of anti-CD20 antibodies to chemotherapy, defining a new standard of care for many years. More recently, therapies targeting fundamental signaling and anti-apoptotic pathways within the CLL cell have demonstrated dramatic clinical responses, including in patients with high-risk prognostic markers, thus emerging as preferred therapy for many patients. While the addition of anti-CD20 antibodies to traditional chemotherapy resulted in significant improvements in outcomes, the role of monoclonal antibodies in the era of targeted agents remains an active area of investigation. Furthermore, since the advent of next-generation anti-CD20 antibodies, the role of specific anti-CD20 antibodies remains an open question. AREAS COVERED In this review, we highlight the important role that anti-CD20 antibody therapy has had in the field of CLL, both when used with chemotherapy and in combination with targeted therapy, as well as the current studies that are further exploring this treatment paradigm in the modern era. EXPERT OPINION While anti-CD20 antibodies have played a pivotal role in the treatment of CLL, additional studies will be required to determine the optimal application of these therapies in combination with targeted therapy.

Abstract
ABSTRACT In this article, we carry out an overview on the management options available for chronic lymphocytic leukemia (CLL) patients and discuss possible treatment decisions, taking into account the issue of sustainability and availability. Targeted agents have shown to be superior compared with chemoimmunotherapy (CIT) in terms of progression-free survival in high-risk CLL. In the majority of studies, however, continuous treatment was compared with fixed-duration CIT and no overall survival or progression-free survival-2 (time from randomization to second progression or death) advantage could be documented. Meanwhile, a substantial financial burden on both patients and payers has raised issues about affordability and adherence to treatment. Therefore, value-based pricing of new drugs has been used to set up price negotiation policies in several countries, and fixed-duration therapy has shown to be less costly than continuous treatment. Thus, CIT continues to have a role in the treatment of CLL patients with a favorable genetic profile, that is, with a mutated IGHV gene profile and a wild-type TP53. Targeted treatment represents the preferred choice in patients with an unmutated IGHV gene configuration and/or a TP53 disruption, provided that adherence to treatment is guaranteed and bearing in mind that should costly drugs not be available for frontline treatment, new agents can be very effective as first salvage treatment.

Abstract
Ibrutinib represents extraordinary progress in the treatment of chronic lymphocytic leukemia (CLL). However, treatment-related adverse events limit the benefit of this agent. This observational, multicenter study focused on the incidence, risk factors, and prognostic impact of infections in 494 patients with CLL treated with an ibrutinib-based treatment. Ibrutinib was given to 89 (18%) previously untreated patients (combined with rituximab, 24) and 405 (82%) relapsed/refractory patients. Pneumonia (PN), grade ≥3 non-opportunistic infections (NOI), and opportunistic infections (OI) were recorded in 32% of patients with an overall incidence rate per 100 person-year of 15.3% (PN, 10%; NOI, 3.3%; OI, 2%). Infections were the reason for the permanent discontinuation of ibrutinib in 9% of patients. Patients who experienced pneumonia or a severe infection showed a significantly inferior survival than those who were infection-free (p < 0.0001). A scoring system based on the three factors associated with a significant and independent impact on infections-PN or severe infection in the year before starting ibrutinib, chronic obstructive pulmonary disease, ≥2 prior treatments-identified patients with a two- to threefold increase in the rate of infections. In conclusion, the results of this study highlight the adverse impact of infectious events on the outcomes of CLL patients treated with ibrutinib.

Abstract
Targeting the B-cell receptor signaling pathway through BTK inhibition proved to be effective for the treatment of chronic lymphocytic leukemia (CLL) and other B-cell lymphomas. Covalent BTK inhibitors (BTKis) led to an unprecedented improvement in outcome in CLL, in particular for high-risk subgroups with TP53 aberration and unmutated immunoglobulin heavy-chain variable-region gene (IGHV). Ibrutinib and acalabrutinib are approved by the US Food and Drug Administration for the treatment of CLL and other B-cell lymphomas, and zanubrutinib, for patients with mantle cell lymphoma. Distinct target selectivity of individual BTKis confer differences in target-mediated as well as off-target adverse effects. Disease progression on covalent BTKis, driven by histologic transformation or selective expansion of BTK and PLCG2 mutated CLL clones, remains a major challenge in the field. Fixed duration combination regimens and reversible BTKis with non-covalent binding chemistry hold promise for the prevention and treatment of BTKi-resistant disease.

Abstract
Recent advances in treatment have transformed the management of cancer. Despite these advances, cardiovascular disease remains a leading cause of death in cancer survivors. Cardio-oncology has recently evolved as a subspecialty to prevent, diagnose, and manage cardiovascular side effects of antineoplastic therapy. An emphasis on optimal management of comorbidities and close attention to drug interactions are important in cardio-oncologic care. With interdisciplinary collaboration among oncologists, cardiologists, and pharmacists, there is potential to prevent and reduce drug-related toxicities of treatments. The cytochrome P450 (CYP450) family of enzymes and the P-glycoprotein (P-g) transporter play a crucial role in drug metabolism and drug resistance. Here we discuss the role of CYP450 and P-g in drug interactions in the field of cardio-oncology, provide an overview of the cardiotoxicity of a spectrum of cancer agents, highlight the role of precision medicine, and encourage a multidisciplinary treatment approach for patients with cancer.

Abstract
Since the first clinical report in 2013, inhibitors of the intracellular kinase BTK (BTKi) have profoundly altered the treatment paradigm of B cell malignancies, replacing chemotherapy with targeted agents in patients with chronic lymphocytic leukemia (CLL), mantle cell lymphoma (MCL), and Waldenström's macroglobulinemia. There are over 20 BTKi, both irreversible and reversible, in clinical development. While loss-of-function (LoF) mutations in the BTK gene cause the immunodeficiency X-linked agammaglobulinemia, neither inherited, nor somatic BTK driver mutations are known. Instead, BTKi-sensitive malignancies are addicted to BTK. BTK is activated by upstream surface receptors, especially the B cell receptor (BCR) but also by chemokine receptors, and adhesion molecules regulating B cell homing. Consequently, BTKi therapy abrogates BCR-driven proliferation and the tissue homing capacity of the malignant cells, which are being redistributed into peripheral blood. BTKi resistance can develop over time, especially in MCL and high-risk CLL patients. Frequently, resistance mutations affect the BTKi binding-site, cysteine 481, thereby reducing drug binding. Less common are gain-of-function (GoF) mutations in downstream signaling components, including phospholipase Cγ2 (PLCγ2). In a subset of patients, mechanisms outside of the BCR pathway, related e.g. to resistance to apoptosis were described. BCR signaling depends on many proteins including SYK, BTK, PI3K; still based on the resistance pattern, BTKi therapy only selects GoF alterations in the NF-κB arm, whereas an inhibitor of the p110δ subunit of PI3K instead selects resistance mutations in the RAS-MAP kinase pathway. BTK and PLCγ2 resistance mutations highlight BTK's non-redundant role in BCR-mediated NF-κB activation. Of note, mutations affecting BTK tend to generate clone sizes larger than alterations in PLCγ2. This infers that BTK signaling may go beyond the PLCγ2-regulated NF-κB and NFAT arms. Collectively, when comparing the primary and acquired mutation spectrum in BTKi-sensitive malignancies with the phenotype of the corresponding germline alterations, we find that certain observations do not readily fit with the existing models of BCR signaling.

Abstract
Patients with chronic lymphocytic leukemia (CLL) typically suffer from frequent and severe bacterial infections. Although it is well known that neutrophils are critical innate immune cells facilitating the early defense, the underlying phenotypical and functional changes in neutrophils during CLL remain largely elusive. Using a murine adoptive transfer model of CLL, we demonstrate aggravated bacterial burden in CLL-bearing mice upon a urinary tract infection with uropathogenic Escherichia coli. Bioinformatic analyses of the neutrophil proteome revealed increased expression of proteins associated with interferon signaling and decreased protein expression associated with granule composition and neutrophil migration. Functional experiments validated these findings by showing reduced levels of myeloperoxidase and acidification of neutrophil granules after ex vivo phagocytosis of bacteria. Pathway enrichment analysis indicated decreased expression of molecules critical for neutrophil recruitment, and migration of neutrophils into the infected urinary bladder was significantly reduced. These altered migratory properties of neutrophils were also associated with reduced expression of CD62L and CXCR4 and correlated with an increased incidence of infections in patients with CLL. In conclusion, this study describes a molecular signature of neutrophils through proteomic, bioinformatic, and functional analyses that are linked to a reduced migratory ability, potentially leading to increased bacterial infections in patients with CLL.

Abstract
BACKGROUND AND OBJECTIVE In order to integrate the existing and inconsistent information from clinical trials and real-world practice on chronic lymphocytic leukemia (CLL) treated with ibrutinib, this analysis aimed to describe the prescription pattern of new users of ibrutinib affected by CLL, focusing on discontinuation, severe adverse events (AEs) and change of treatment, and to assess the integrated healthcare expenditure from the Italian National Health System (INHS) perspective. METHODS Starting from the ReS database, adults with at least a supply of ibrutinib (ATC code L01XE27) were selected from 01/01/2016 to 12/31/2017. Those without any ibrutinib supply in the year before the index prescription were considered new users. Out of them, only patients with at least a primary or secondary in-hospital diagnosis of CLL (ICD-9-CM code 204.1*) from 01/01/2013 to 12/31/2018 were further broken down according to the ibrutinib's line treatment (first line-FL; second or later line-SLL) and analysed. They were characterized by sex and age in the selection period. Mean annual consumption (defined daily doses [DDD]), treatment discontinuation, changes of therapy, interruptions and healthcare costs in charge of the INHS were assessed during two follow-up years. RESULTS Out of more than 5 million inhabitants of the ReS database, 69 new ibrutinib users and diagnosed with CLL in 2016 (incidence: 1.6 × 100,000) and 41 in 2017 (incidence: 0.9 × 100,000) were selected. Of these, 21 (19.1%) were FL ibrutinib users and 89 (80.9%) were SLL ones, mostly males and with mean ages (±SD) of 65 ± 14 and 70 ± 10, respectively. The mean annual consumption among FL users decreased from 222.2 DDD per patient treated to 216.0 DDD, while increased among SLL patients from 238.6 DDD to 260.1 DDD, in the first and second follow-up year, respectively. The discontinuation rate was about 40% in the first year, similarly among FL and SLL users. SLL patients discontinued more frequently (52.8% vs 20.0%) in the second year. Very few AEs were recorded. The 62.5% of FL and 55.6% of SLL users discontinuing ibrutinib in 1-year follow-up, while one SLL patient (5.3%) in the second year changed therapy. The 20.0% and 15.9% of all new users in first and second year interrupted ibrutinib. The total integrated cost of FL patients was €55,732 reducing by about €15,000, while it was €58,716 for SLL ones decreasing by €6,000, respectively, in the first and in the second year. Pharmaceuticals were the key cost driver (ibrutinib accounted for more than 77%). CONCLUSIONS This analysis on Italian administrative data provided results about prescription patterns of ibrutinib FL and SLL new users with CLL, focusing on discontinuation, treatment change and healthcare costs over 2-year follow-up, and contributed to improve the knowledge on this hard-to-treat disease.

Phase 2 study of the safety and efficacy of umbralisib in patients with CLL who are intolerant to BTK or PI3Kδ inhibitor therapy. Blood 2021; 137:2817-2826. [PMID: 33259589 PMCID: PMC8574211 DOI: 10.1182/blood.2020007376] [Citation(s) in RCA: 34] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 11/09/2020] [Indexed: 01/31/2023] Open
Abstract
Intolerance is the most common reason for kinase inhibitor (KI) discontinuation in chronic lymphocytic leukemia (CLL). Umbralisib, a novel highly selective phosphatidylinositol 3-kinase δ (PI3Kδ)/CK1ε inhibitor, is active and well tolerated in CLL patients. In this phase 2 trial (NCT02742090), umbralisib was initiated at 800 mg/d in CLL patients requiring therapy, who were intolerant to prior BTK inhibitor (BTKi) or PI3K inhibitor (PI3Ki) therapy, until progression or toxicity. Primary end point was progression-free survival (PFS). Secondary end points included time to treatment failure and safety. DNA was genotyped for CYP3A4, CYP3A5, and CYP2D6 polymorphisms. Fifty-one patients were enrolled (44 BTKi intolerant and 7 PI3Kδi intolerant); median age was 70 years (range, 48-96), with a median of 2 prior lines of therapy (range, 1-7), 24% had del17p and/or TP53 mutation, and 65% had unmutated IGHV. Most common adverse events (AEs) leading to prior KI discontinuation were rash (27%), arthralgia (18%), and atrial fibrillation (16%). Median PFS was 23.5 months (95% CI, 13.1-not estimable), with 58% of patients on umbralisib for a longer duration than prior KI. Most common (≥5%) grade ≥3 AEs on umbralisib (all causality) were neutropenia (18%), leukocytosis (14%), thrombocytopenia (12%), pneumonia (12%), and diarrhea (8%). Six patients (12%) discontinued umbralisib because of an AE. Eight patients (16%) had dose reductions and were successfully rechallenged. These are the first prospective data to confirm that switching from a BTKi or alternate PI3Ki to umbralisib in this BTKi- and PI3Ki-intolerant CLL population can result in durable well-tolerated responses.

Abstract
Pharmacological inhibitors of Bruton tyrosine kinase (BTK) have revolutionized treatment of B-lymphocyte malignancies and show great promise for dampening autoimmunity. The predominant BTK inhibitors tether irreversibly by covalently binding to cysteine 481 in the BTK catalytic domain. Substitution of cysteine 481 for serine (C481S) is the most common mechanism for acquired drug resistance. We generated a novel C481S knock-in mouse model and, using a battery of tests, no overt B-lymphocyte phenotype was found. B lymphocytes from C481S animals were resistant to irreversible, but sensitive to reversible, BTK inhibitors. In contrast, irreversible inhibitors equally impaired T-lymphocyte activation in mice, mimicking the effect of treatment in patients. This demonstrates that T-lymphocyte blockage is independent of BTK. We suggest that the C481S knock-in mouse can serve as a useful tool for the study of BTK-independent effects of irreversible inhibitors, allowing for the identification of novel therapeutic targets and pinpointing potential side effects.

Abstract
Primary central nervous system (CNS) lymphoma (PCNSL) is a rare type of extranodal lymphoma exclusively involving the CNS at the onset, with diffuse large B-cell lymphoma (DLBCL) as the most common histological subtype. As PCNSL is a malignancy arising in an immune-privileged site, suboptimal delivery of systemic agents into tumor tissues results in poorer outcomes in PCNSL than in non-CNS DLBCLs. Commonly used regimens for PCNSL include high-dose methotrexate-based chemotherapy with rituximab for induction therapy and intensive chemotherapy followed by autologous hematopoietic stem cell transplantation or whole-brain radiotherapy for consolidation therapy. Targeted agents against the B-cell receptor signaling pathway, microenvironment immunomodulation and blood-brain barrier (BBB) permeabilization appear to be promising in treating refractory/relapsed patients. Chimeric antigen receptor-T cells (CAR-T cells) have been shown to penetrate the BBB as a potential tool to manipulate this disease entity while controlling CAR-T cell-related encephalopathy syndrome. Future approaches may stratify patients according to age, performance status, molecular biomarkers and cellular bioinformation. This review summarizes the current therapies and emerging agents in clinical development for PCNSL treatment.

Abstract
Treatment outcomes of relapsed/refractory diffuse large B cell lymphoma (R/R DLBCL) are far from satisfactory. Certain efficacy of ibrutinib has been observed in non-GCB subtype DLBCL patients. This study aimed to investigate the efficacy and safety of ibrutinib plus BCL2 inhibitor venetoclax in R/R DLBCL patients with non-GCB subtype and BCL2 overexpression. Combinational therapy (ibrutinib 560mg/day; venetoclax started 1 week later, oral dose increased from 100 to 400mg/day in 3 weeks) was conducted, and one cycle was 4 weeks. Both drugs were stopped when disease progress or serious adverse reactions appear. The primary end-point was overall response rate (ORR) at two cycles. From December 2018 to July 2020, a total of 13 patients were treated with the combined therapy. Among them, eleven (84.6%) patients previously received at least two treatment regimens, eight (61.5%) patients were C-myc and BCL2 double expression. The ORR at two cycles was 61.5%, with 3 (23.1%) patients achieved complete remission (CR) and 5 (38.4%) patients achieved partial remission (PR). The ORR at four cycles and six cycles was 53.8% and 46.2%, respectively. The median duration of response was 11 months (range, 1.5-13.6 months). The median progression-free survival and overall survival were 5.6 months (range, 0.4-15.6) and 11.3 months (range, 2.8-17.2), respectively. The most common adverse event was grade 1/2 neutropenia (53.8%), and nonhematologic toxicities included Grade1/2 diarrhea (46.2%) and elevated liver enzymes (30.8%). Combined therapy of ibrutinib and venetoclax showed promising efficacy and synergistic effects in R/R DLBCL patients with non-GCB subtype and BCL2 overexpression, and the toxicities were well-tolerated.

Abstract
Identifying precise targets of individual cancers remains challenging. Chronic lymphocytic leukemia (CLL) represents the most common adult hematologic malignancy, and trisomy 12 (tri12) represents a quarter of CLL patients. We report that tri12 human pluripotent stem cells (hPSCs) allow for the identification of gene networks and targets specific to tri12, which are controlled by comparative normal PSCs. Identified targets are upregulated in tri12 leukemic cells from a cohort of 159 patients with monoclonal B cell lymphocytosis and CLL. tri12 signaling patterns significantly influence progression-free survival. Actionable targets are identified using high-content drug testing and functionally validated in an additional 44 CLL patient samples. Using xenograft models, interleukin-1 receptor-associated kinase 4 (IRAK4) inhibitor is potent and selective against human tri12 CLL versus healthy patient-derived xenografts. Our study uses hPSCs to uncover targets from genetic aberrations and apply them to cancer. These findings provide immediate translational potential as biomarkers and targets for therapeutic intervention.

Abstract
The cytoplasmic protein-tyrosine kinase BTK plays an essential role for differentiation and survival of B-lineage cells and, hence, represents a suitable drug target. The number of BTK inhibitors (BTKis) in the clinic has increased considerably and currently amounts to at least 22. First-in-class was ibrutinib, an irreversible binder forming a covalent bond to a cysteine in the catalytic region of the kinase, for which we have identified 228 active trials listed at ClinicalTrials.gov. Next-generation inhibitors, acalabrutinib and zanubrutinib, are approved both in the United States and in Europe, and zanubrutinib also in China, while tirabrutinib is currently only registered in Japan. In most cases, these compounds have been used for the treatment of B-lymphocyte tumors. However, an increasing number of trials instead addresses autoimmunity and inflammation in multiple sclerosis, rheumatoid arthritis, pemphigus and systemic lupus erythematosus with the use of either irreversibly binding inhibitors, e.g., evobrutinib and tolebrutinib, or reversibly binding inhibitors, like fenebrutinib. Adverse effects (AEs) have predominantly implicated inhibition of other kinases with a BTKi-binding cysteine in their catalytic domain. Analysis of the reported AEs suggests that ibrutinib-associated atrial fibrillation is caused by binding to ERBB2/HER2 and ERBB4/HER4. However, the binding pattern of BTKis to various additional kinases does not correlate with the common assumption that skin manifestations and diarrhoeas are off-target effects related to EGF receptor inhibition. Moreover, dermatological toxicities, diarrhoea, bleedings and invasive fungal infections often develop early after BTKi treatment initiation and subsequently subside. Conversely, cardiovascular AEs, like hypertension and various forms of heart disease, often persist.

Clinical and biological implications of target occupancy in CLL treated with the BTK inhibitor acalabrutinib. Blood 2021; 136:93-105.

Abstract
Inhibition of the B-cell receptor pathway, and specifically of Bruton tyrosine kinase (BTK), is a leading therapeutic strategy in B-cell malignancies, including chronic lymphocytic leukemia (CLL). Target occupancy is a measure of covalent binding to BTK and has been applied as a pharmacodynamic parameter in clinical studies of BTK inhibitors. However, the kinetics of de novo BTK synthesis, which determines occupancy, and the relationship between occupancy, pathway inhibition and clinical outcomes remain undefined. This randomized phase 2 study investigated the safety, efficacy, and pharmacodynamics of a selective BTK inhibitor acalabrutinib at 100 mg twice daily (BID) or 200 mg once daily (QD) in 48 patients with relapsed/refractory or high-risk treatment-naïve CLL. Acalabrutinib was well tolerated and yielded an overall response rate (ORR) of partial response or better of 95.8% (95% confidence interval [CI], 78.9-99.9) and an estimated progression-free survival (PFS) rate at 24 months of 91.5% (95% CI, 70.0-97.8) with BID dosing and an ORR of 79.2% (95% CI, 57.9-92.9) and an estimated PFS rate at 24 months of 87.2% (95% CI, 57.2-96.7) with QD dosing. BTK resynthesis was faster in patients with CLL than in healthy volunteers. BID dosing maintained higher BTK occupancy and achieved more potent pathway inhibition compared with QD dosing. Small increments in occupancy attained by BID dosing relative to QD dosing compounded over time to augment downstream biological effects. The impact of BTK occupancy on long-term clinical outcomes remains to be determined. This trial was registered at www.clinicaltrials.gov as #NCT02337829.

Abstract
The treatment landscape of chronic lymphocytic leukemia (CLL) has significantly changed in the past decade. This paradigm shift is due to the introduction of novel agents to the field. The two major classes of drugs that have contributed to this dramatic evolution include the Bruton tyrosine kinase (BTK) inhibitors and BCL2 inhibitors. Ibrutinib was the first-in-class drug which was initially approved by the US Food and Drug Administration (FDA) for the treatment of patients with relapsed/refractory and later for patients with treatment-naïve CLL. Despite encouraging efficacy outcomes, its use has been associated with cardiovascular and gastrointestinal toxicities likely due to off-target inhibition of ITK, TEC and EGFR family kinases. The next generation of BTK inhibitors was developed to be more selective with less off-target inhibition with the prospect to improve tolerability without compromising efficacy. Acalabrutinib, a selective covalent BTK inhibitor, is a second generation BTK inhibitor. The focus of this review is on two major phase III trials that resulted in the FDA approval of acalabrutinib in 2019. The ELEVATE TN trial investigated acalabrutinib with or without obintuzumab versus chlorambucil-obinutuzumab in older and frail patients with previously untreated CLL. The ASCEND trial explored acalabrutinib versus chemoimmunotherapy in patients with relapsed/refractory CLL. Both trials demonstrated superiority of the acalabrutinib-containing arms in terms of both efficacy and tolerability. Unfortunately, the availability of new generation BTK inhibitors has not resulted in mitigating the financial toxicities associated with these potentially life-long treatments.

Abstract
Purpose: We describe a case vision-threatening sclerouveitis as a probable adverse drug reaction to ibrutinib. Methods: Case report. Results: Ibrutinib is an inhibitor of Bruton's kinase which has shown success in the treatment of hematological malignancies such as chronic lymphocytic leukemia. Despite being generally well tolerated, recent studies have implicated ibrutinib in several adverse events affecting organs such as the heart, intestines, and the eyes. We present the case of a patient who developed severe sclerouveitis after approximately one year of ibrutinib therapy, and suggest this is a probable adverse drug reaction associated with ibrutinib in accordance with the Naranjo algorithm, highlighting the importance of prompt management of ocular symptoms in these patients.

Abstract
We present a case of a 74-year-old woman with chronic lymphocytic leukemia (CLL) who presented with unilateral blurry vision that had progressively worsened over a few weeks. Ophthalmic examination revealed unilateral anterior chamber, vitreous body inflammation along with retinal infiltration which was initially diagnosed with posterior uveitis. Analysis of vitreous fluid aspiration was negative for bacteria, fungal and viral etiologies. Despite the broad-spectrum intraocular antibiotics, her vision continued to decline, and she later developed retinal detachment. Cytology for lymphoma was negative. However, polymerase chain reaction (PCR) with internal transcribed spacer-specific (ITS) primer set detected Toxoplasma gondii, and the patient was diagnosed with intraocular toxoplasmosis. Treatment with systemic clindamycin, pyrimethamine, leucovorin, prednisone, and topical clindamycin for four weeks successfully prevented further ocular damage.

Abstract
Ibrutinib is an orally bioavailable, irreversible selective Bruton’s tyrosine kinase inhibitor that has demonstrated impressive therapeutic effects in patients with B cell malignancies. However, adverse effects, such as bleeding and hypertension, are also reported, implying that studies on the toxicological effect of ibrutinib on living organisms are needed. Here, we have used zebrafish, a successful model organism for studying toxicology, to investigate the influence of ibrutinib during embryogenesis. We found that ibrutinib had potent toxicity on embryonic development, especially vascular development in zebrafish embryos. We also revealed that ibrutinib perturbed vascular formation by suppressing angiogenesis, rather than vasculogenesis. In addition, ibrutinib exposure led to the collapse of the vascular lumen, as well as reduced proliferation and enhanced apoptosis of vascular endothelial cells. Moreover, the expression of vascular development-related genes was also altered in ibrutinib-treated embryos. To our knowledge, this is the first study to describe the vascular toxicity of ibrutinib in an animal model, providing a theoretical basis for clinical safety guidelines in ibrutinib treatment.

Abstract
PURPOSE OF REVIEW Ibrutinib is a first-in-class, highly potent Bruton tyrosine kinase inhibitor which has become standard of care for patients with chronic lymphocytic leukaemia and other lymphoproliferative disorders. It requires indefinite administration which places emphasis on toxicity and long-term tolerance. RECENT FINDINGS Extensive use of ibrutinib in studies and clinical practice has better defined its full toxicity profile which has made its use more challenging than initially foreseen. In particular, dysrhythmias, bleeding, infections and constitutional symptoms have been reported and can result in dose reduction or discontinuation of ibrutinib. Herein, we review the common as well as rare but important toxicities and discuss approach and management on a practical level. We also highlight that patients should be regularly monitored for adverse events and proactively treated to minimise side effects and avoid disruption.

Abstract
Inhibition of Bruton's tyrosine kinase (BTK) has revolutionized the treatment landscape for patients with chronic lymphocytic leukemia (CLL). By targeting this critical kinase in proximal B-cell receptor signaling, BTK inhibitors (BTKis) impair cell proliferation, migration, and activation of NF-κB. Clinically, because indefinite inhibition is a mainstay of therapy, there is an extended period of exposure in which adverse effects can develop. Given the impressive efficacy and activity of BTKis in the treatment of patients with CLL, appropriate management of treatment-emergent adverse events (AEs) is of paramount importance. Here we review the BTKi landscape and present the available toxicity and safety data for each agent. The long-term toxicity profile of ibrutinib, a first-in-class inhibitor, is well characterized and includes a clinically significant incidence of cardiac arrhythmias, bleeding, infection, diarrhea, arthralgias, and hypertension. Acalabrutinib, the initial second-generation BTKi to earn approval from the US Food and Drug Administration, demonstrates improved kinase selectivity for BTK, with commonly observed adverse reactions including infection, headache, and diarrhea. Mediated by both on-target inhibition of BTK and variable off-target inhibition of other kinases including interleukin-2-inducible T-cell kinase (ITK), tyrosine-protein kinase (TEC), and endothelial growth factor receptor (EGFR), the toxicity profile of BTKis is closely linked to their pattern of kinase binding. Other emerging BTKis include second-generation agents with variable degrees of kinase selectivity and third-generation agents that exhibit reversible noncovalent binding to BTK. We also highlight critical considerations for the prevention and monitoring of AEs and offer practical management strategies for treatment-emergent toxicities.

Abstract
BACKGROUND Inhibitors of tyrosine kinases downstream of the B-cell receptor, such as Bruton's tyrosine kinase (Btk) or Spleen tyrosine kinase (Syk), used alone or in combination are new therapeutic options in the treatment of B-cell malignancies. A challenge in the development of second-generation Btk inhibitors is to limit their side effects such as the increased bleeding risk. Considering the pivotal role of Syk in immunoreceptor tyrosine-based activation motif mediated platelet signaling, the impact of inhibiting this kinase on platelet functions is also worth analyzing. OBJECTIVES We investigated the effect of a novel Btk inhibitor, tirabrutinib, and a Syk inhibitor, entospletinib, alone and in combination on platelet signaling and functions in vitro and ex vivo. METHODS Platelet aggregation, secretion, and signaling responses as well as thrombus growth under flow were analyzed in the presence of the inhibitors alone or in combination in vitro, at clinically relevant doses, and ex vivo in patients treated with these inhibitors in the context of a phase I trial. RESULTS Although tirabrutinib alone had modest effects on platelet activation in vitro and ex vivo, entospletinib alone efficiently inhibited washed platelet aggregation in response to collagen. However, entospletinib weakly affected platelet activation in platelet-rich plasma, in whole blood and ex vivo. Importantly, the combination of tirabrutinib and entospletinib induced a significant decrease in platelet response to collagen in vitro and ex vivo correlating with mild bleedings reported in some of the treated patients. CONCLUSION These new results should contribute to improve the safety of these targeted therapies.

Abstract
The development of Bruton's tyrosine kinase (BTK) inhibitors represents a major breakthrough in the treatment of chronic lymphocytic leukemia and other B cell malignancies. The first-generation inhibitor ibrutinib works by covalent irreversible binding to BTK, a non-receptor tyrosine kinase of the TEC (transient erythroblastopenia of childhood) family that plays a critical role in the B-cell receptor signaling pathway. It also induces an 'off-target' inhibition of a range of other kinases including (but not limited to) epidermal growth factor receptor (EGFR), SRC, and other kinases of the TEC family (interleukin-2-inducible T-cell kinase [ITK], Tec, BMX). Dermatological toxicities are among the most common toxicities of ibrutinib, but remain of mild to moderate intensity in most cases and are readily manageable. Their incidence is highest during the first year of treatment and declines over time. In addition, it has been postulated that ibrutinib-related dermatologic adverse events are mediated by the direct binding to both BTK and other 'off-target' kinases. Bruising, ecchymoses, and petechiae represent the most characteristic dermatologic adverse events. Nail and hair changes are also common, as skin infections (opportunistic infections including herpes simplex and herpes zoster virus reactivations, and Staphylococcus aureus superinfection), folliculitis, and other types of rashes. Panniculitis, aphthous-like ulcerations with stomatitis, neutrophilic dermatosis, peripheral edema, and skin cracking can also occur. Next-generation BTK inhibitors, acalabrutinib and zanubrutinib, have been designed to optimize BTK inhibition and minimize off-target inhibition of alternative kinases (Tec, ITK, EGFR, SRC-family kinases). These drugs have been recently FDA-approved for relapsed or refractory mantle cell lymphoma. Although the overall incidence of their toxicities is expected to be more limited, acalubrutinib and zanubrutinib are associated with a range of dermatologic toxic effects that appear to be similar to those previously described with ibrutinib, including bruising and ecchymoses, panniculitis, human herpesvirus infections, cellulitis, and skin rash. In particular, both drugs induce skin bleeding events in more than 30% of patients treated. However, the available dermatological data are still rather limited and will have to be consolidated prospectively. This review article analyses the wide spectrum of dermatological toxicities that can be encountered with first- and second-generation BTK inhibitors. Finally, recommendations for appropriate treatment as well as a synthesis algorithm for management are also proposed.

Br J Haematol 2020; 193:15-25. [PMID: 33216986 DOI: 10.1111/bjh.17184] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 08/20/2020] [Accepted: 08/25/2020] [Indexed: 01/15/2023]
Abstract
Greater understanding of the mechanisms involved in the disease progression of haematological malignancies has led to the introduction of novel targeted therapies with reduced toxicity compared with chemotherapy-based regimens, which has expanded the treatment options for patients with mantle cell lymphoma (MCL) and chronic lymphocytic leukaemia/small lymphocytic lymphoma (CLL/SLL). Ibrutinib is a first-in-class Bruton tyrosine kinase (BTK) inhibitor indicated for the treatment of patients with CLL/SLL or relapsed/refractory MCL. However, next-generation BTK inhibitors have been developed with improved specificity and the potential to reduce the off-target toxicity observed with ibrutinib. Acalabrutinib is a highly selective, next-generation BTK inhibitor, which was granted accelerated approval by the US Food and Drug Administration in 2017 for the treatment of adult patients with MCL who have received at least one prior therapy. In November 2019, it was also granted approval for the treatment of adult patients with CLL/SLL on the basis of two phase 3 clinical trials. This review describes the current understanding of acalabrutinib according to clinical study data for the treatment of MCL and CLL/SLL and shares recommendations from our practice on how it should be used when treating patients in the clinic, including dosing, administration and management of adverse events.

Abstract
Recurrent genetic aberrations have long been recognized in mature lymphoid leukemias and lymphomas. As conventional karyotypic and molecular cloning techniques evolved in the 1970s and 1980s, multiple cytogenetic aberrations were identified in lymphomas, often balanced translocations that juxtaposed oncogenes to the immunoglobulin (IG) or T-cell receptor (TR) loci, leading to dysregulation. However, genetic characterization and classification of lymphoma by conventional cytogenetic methods is limited by the infrequent occurrence of recurrent karyotypic abnormalities in many lymphoma subtypes and by the frequent difficulty in growing clinical lymphoma specimens in culture to obtain informative karyotypes. As higher-resolution genomic techniques developed, such as array comparative genomic hybridization and fluorescence in situ hybridization, many recurrent copy number changes were identified in lymphomas, and copy number assessment of interphase cells became part of routine clinical practice for a subset of diseases. Platforms to globally examine mRNA expression led to major insights into the biology of several lymphomas, although these techniques have not gained widespread application in routine clinical settings. With the advent of next-generation sequencing (NGS) techniques in the early 2000s, numerous insights into the genetic landscape of lymphomas were obtained. In contrast to the myeloid malignancies, most common lymphomas exhibit an at least somewhat mutationally complex genome, with few single driver mutations in the majority of patients. However, many recurrently mutated pathways have been identified across lymphoma subtypes, informing targeted therapeutic approaches that are beginning to make meaningful changes in the treatment of lymphoma. In addition to the ability to identify possible therapeutic targets, NGS techniques are highly amenable to the tracking of residual lymphoma following therapy, because of the presence of unique genetic "fingerprints" in lymphoma cells due to V(D)-J recombination at the antigen receptor loci. This review will provide an overview of the impact of novel genetic technologies on lymphoma classification, biology, and therapy.
