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.

Disease Flare During Temporary Interruption of Ibrutinib Therapy in Patients with Chronic Lymphocytic Leukemia. Oncologist 2020; 25:974-980. [PMID: 32886416 DOI: 10.1634/theoncologist.2020-0388] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Accepted: 08/18/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Approximately 25% of patients with chronic lymphocytic leukemia (CLL) experience a flare of disease following ibrutinib discontinuation. A critical question is whether this phenomenon may also occur when ibrutinib is temporarily held. This study aimed to determine the frequency and characteristics of disease flares in this setting and assess risk factors and clinical outcomes. MATERIALS AND METHODS We identified all patients with CLL seen at Mayo Clinic between October 2012 and March 2019 who received ibrutinib. Temporary interruptions in treatment and associated clinical findings were ascertained. RESULTS Among the 372 patients identified, 143 (38%) had at least one temporary interruption (median 1 hold, range 1-7 holds) in treatment. The median duration of interruption was 8 days (range 1-59 days) and the most common indication was periprocedural. Among the 143 patients with ≥1 hold, an associated disease flare was seen in 35 (25%) patients: mild (constitutional symptoms only) in 21 patients and severe (constitutional symptoms with exam/radiographic findings or laboratory changes) in 14 patients. Disease flare resolved with resuming ibrutinib in all patients. Predictive factors of disease flare included progressive disease at time of hold and ≥ 24 months of ibrutinib exposure. The occurrence of disease flare with an ibrutinib hold was associated with shorter event-free survival (hazard ratio 2.3; 95% confidence interval 1.3-4.1; p = .007) but not overall survival. CONCLUSION Temporary interruptions in ibrutinib treatment of patients with CLL are common, and one quarter of patients who held ibrutinib in this study experienced a disease flare. Resolution with resuming ibrutinib underscores the importance of awareness of this phenomenon for optimal management. IMPLICATIONS FOR PRACTICE Ibrutinib is a very effective treatment for chronic lymphocytic leukemia (CLL) but needs to be taken continuously. Side effects, such as increased bleeding risk with procedures, require temporary interruptions in this continuous treatment. Rapid CLL progression following ibrutinib discontinuation has been increasingly recognized. This study demonstrates that similar flares in disease signs or symptoms may occur during ibrutinib holds as well. Importantly, management with restarting ibrutinib led to quick clinical improvement. Awareness of this phenomenon among clinicians is critical to avoid associated patient morbidity and premature cessation of effective treatment with ibrutinib if the flare is misidentified as true progression of disease.

Abstract
PURPOSE Acalabrutinib, a highly selective, potent, Bruton tyrosine kinase inhibitor, was evaluated in this global, multicenter, randomized, open-label, phase III study in patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL). METHODS Eligible patients, aged ≥ 18 years with R/R CLL, were randomly assigned 1:1 centrally and stratified by del(17p) status, Eastern Cooperative Oncology Group performance status score, and number of prior lines of therapy. Patients received acalabrutinib monotherapy or investigator's choice (idelalisib plus rituximab [I-R] or bendamustine plus rituximab [B-R]). The primary end point was progression-free survival (PFS) assessed by an independent review committee (IRC) in the intent-to-treat population. Key secondary end points included IRC-assessed overall response rate, overall survival, and safety. RESULTS From February 21, 2017, to January 17, 2018, a total of 398 patients were assessed for eligibility; 310 patients were randomly assigned to acalabrutinib monotherapy (n = 155) or investigator's choice (n = 155; I-R, n = 119; B-R, n = 36). Patients had received a median of two prior therapies (range, 1-10). After a median follow-up of 16.1 months (range, 0.03-22.4 months), median PFS was significantly longer with acalabrutinib monotherapy (PFS not reached) compared with investigator's choice (16.5 months [95% CI, 14.0 to 17.1 months]; hazard ratio, 0.31 [95% CI, 0.20 to 0.49]; P < .0001). Estimated 12-month PFS was 88% (95% CI, 81% to 92%) for acalabrutinib and 68% (95% CI, 59% to 75%) for investigator's choice. Serious adverse events occurred in 29% of patients (n = 44 of 154) treated with acalabrutinib monotherapy, 56% (n = 66 of 118) with I-R, and 26% (n = 9 of 35) with B-R. Deaths occurred in 10% (n = 15 of 154), 11% (n = 13 of 118), and 14% (n = 5 of 35) of patients receiving acalabrutinib monotherapy, I-R, and B-R, respectively. CONCLUSION Acalabrutinib significantly improved PFS compared with I-R or B-R and has an acceptable safety profile in patients with R/R CLL.

Abstract
AbstractIbrutinib is an irreversible BTK inhibitor, characterized by high selectivity and potency. It has revolutionized the therapy of B-cell lymphomas, especially chronic lymphocytic leukemia (CLL) and mantle cell lymphoma. Importantly, it has expanded the armamentarium for those patients who are refractory to conventional chemoimmunotherapy. This small-molecule inhibitor has shown efficacy in this difficult-to-treat subset – those with del(17p)/TP53-mutated CLL. Its immunomodulatory properties make it an excellent choice for combining with other immunotherapeutic agents such as venetoclax. The drug is not without drawbacks. The need for indefinite therapy and the presence of adverse effects such as infection, bleeding, hypertension, and arrhythmia temper our enthusiasm for this versatile drug. But overall, ibrutinib's favorable risk profile and lack of myelosuppression make it an ideal therapy for the elderly and those with multiple comorbidities.

Abstract
Ibrutinib is a Bruton tyrosine kinase (BTK) inhibitor that has shown significant efficacy in patients with lymphoid carcinomas, mostly chronic lymphocytic leukemia (CLL). Cytomegalovirus (CMV) infection is not a common infectious complication associated with ibrutinib. To increase the clinical awareness about this rare entity, we present the first case of CMV proctitis in an immunocompromised host who was being treated with ibrutinib. An 88-year old female with a history of CLL treated with ibrutinib presented with two days of painless hematochezia. Physical examination revealed cachexia and temporal wasting; bright red blood was observed on the digital rectal examination. A complete blood count demonstrated a significant decrease in hemoglobin from her baseline. Subsequent colonoscopy revealed a circumferential rectal ulcer; biopsy of the rectal ulcer was positive for CMV immunostain. The patient was treated with intravenous ganciclovir and later transitioned to valganciclovir for a total of 21 days of treatment. Her condition resolved, and she was found doing well at the follow-up visit.

Abstract
c-Jun N-terminal kinase (JNK) signalling regulates both cancer cell apoptosis and survival. Emerging evidence show that JNK promoted tumour progression is involved in various cancers, that include human pancreatic-, lung-, and breast cancer. The pro-survival JNK oncoprotein functions in a cell context- and cell type-specific manner to affect signal pathways that modulate tumour initiation, proliferation, and migration. JNK is therefore considered a potential oncogenic target for cancer therapy. Currently, designing effective and specific JNK inhibitors is an active area in the cancer treatment. Some ATP-competitive inhibitors of JNK, such as SP600125 and AS601245, are widely used in vitro; however, this type of inhibitor lacks specificity as they indiscriminately inhibit phosphorylation of all JNK substrates. Moreover, JNK has at least three isoforms with different functions in cancer development and identifying specific selective inhibitors is crucial for the development of targeted therapy in cancer. Some selective inhibitors of JNK are identified; however, their clinical studies in cancer are relatively less conducted. In this review, we first summarised the function of JNK signalling in cancer progression; there is a focus on the discussion of the novel selective JNK inhibitors as potential targeting therapy in cancer. Finally, we have offered a future perspective of the selective JNK inhibitors in the context of cancer therapies. We hope this review will help to further understand the role of JNK in cancer progression and provide insight into the design of novel selective JNK inhibitors in cancer treatment.

Abstract
By increasing disease-free survival and offering the potential for long-term cure, chimeric antigen receptor (CAR) T-cell therapy has dramatically expanded therapeutic options among those with high-risk B-cell malignancies. As CAR T-cell utilization evolves however, novel challenges are generated. These include determining how to optimally integrate CAR T cells into standard of care and overcoming mechanisms of resistance to CAR T-cell therapy, such as evolutionary stress induced on cancer cells leading to immunophenotypic changes that allow leukemia to evade this targeted therapy. Compounding these challenges are the limited ability to determine differences between various CAR T-cell constructs, understanding the generalizability of trial outcomes from multiple sites utilizing unique CAR manufacturing strategies, and comparing distinct criteria for toxicity grading while defining optimal management. Additionally, as understanding of CAR behavior in humans has developed, strategies have appropriately evolved to proactively mitigate toxicities. These challenges offer complimentary insights and guide next steps to enhance the efficacy of this novel therapeutic modality. With a focus on B-cell malignancies as the paradigm for effective CAR T-cell therapy, this review describes advances in the field as well as current challenges and future directions.

Abstract
Chronic lymphocytic leukaemia (CLL), the most frequent type of leukaemia in adults, is a lymphoproliferative disorder that is characterized by the expansion of monoclonal, mature CD5+CD23+ B cells in the peripheral blood, secondary lymphoid tissues and bone marrow. CLL is an incurable disease with a heterogeneous clinical course, for which the treatment decision still relies on conventional parameters (such as clinical stage and lymphocyte doubling time). During the past 5 years, relevant advances have been made in understanding CLL biology. Indeed, substantial progress has been made in the identification of the putative cell of origin of CLL, and comprehensive studies have dissected the genomic, epigenomic and transcriptomic landscape of CLL. Advances in clinical management include improvements in our understanding of the prognostic value of different genetic lesions, particularly those associated with chemoresistance and progression to highly aggressive forms of CLL, and the advent of new therapies targeting crucial biological pathways. In this Review, we discuss new insights into the genetic lesions involved in the pathogenesis of CLL and how these genetic insights influence clinical management and the development of new therapeutic strategies for this disease.

Itraconazole Increases Ibrutinib Exposure 10-Fold and Reduces Interindividual Variation-A Potentially Beneficial Drug-Drug Interaction. Clin Transl Sci 2019; 13:345-351. [PMID: 31664782 PMCID: PMC7070818 DOI: 10.1111/cts.12716] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Accepted: 10/10/2019] [Indexed: 12/31/2022] Open
Abstract
The oral bioavailability of ibrutinib is low and variable, mainly due to extensive first‐pass metabolism by cytochrome P450 (CYP) 3A4. The unpredictable exposure can compromise its safe and effective dosing. We examined the impact of itraconazole on ibrutinib pharmacokinetics. In a randomized crossover study, 11 healthy subjects were administered itraconazole 200 mg or placebo twice on day 1, and once on days 2–4. On day 3, 1 hour after itraconazole (placebo) and breakfast, ibrutinib (140 mg during placebo; 15 mg during itraconazole) was administered. Itraconazole increased the dose‐adjusted geometric mean area under the concentration‐time curve from zero to infinity (AUC0–∞) of ibrutinib 10.0‐fold (90% confidence interval (CI) 7.2–13.9; P < 0.001) and peak plasma concentration (Cmax) 8.8‐fold (90% CI 6.3–12.1; P < 0.001). During itraconazole, the intersubject variation for the AUC0–∞ (55%) and Cmax (53%) was around half of that during placebo (104%; 99%). In conclusion, itraconazole markedly increases ibrutinib bioavailability and decreases its interindividual variability, offering a possibility to improved dosing accuracy and cost savings.

Abstract
The Bruton tyrosine kinase (BTK) inhibitor ibrutinib is increasingly used in the treatment of chronic lymphocytic leukemia (CLL). Moreover, very promising results have been reported in other B-cell malignancies, including primary central nervous system lymphoma (PCNSL). Although well-tolerated in the majority of patients, ibrutinib demonstrates in some cases troublesome toxicities, including invasive fungal infections (IFIs). In the present review, we summarize clinical manifestations of IFIs in patients treated with ibrutinib, generally characterized by an early onset, mild clinical manifestations, asymptomatic/low symptomatic pulmonary localization and high incidence of central nervous system (CNS) involvement. IFI risk appears particularly increased in patients receiving ibrutinib associated with other immune modulator agents, especially with steroids or immune-chemotherapy. Moreover, the immunomodulatory effect of ibrutinib is described, pointing the attention on the involvement of specific molecules targeted by ibrutinib in innate and adaptive response to fungal infection. Overall, the findings indicate the ibrutinib may rapidly impair innate immune cell functions, while concomitantly restoring an effective protective potential of adaptive immune compartment. A correct awareness, especially when other predisposing factors are present, is warranted about the potential risk of IFIs in ibrutinib-treated patients.

Abstract
Oral therapies have become a common treatment choice for several lymphoid cancers. While therapeutic efficacy and patient preference for this therapy type have been reported, there is a lack of knowledge about its effectiveness for lymphoma in clinical practice, particularly in regard to the effects of medication nonadherence. While studies of oral medications in other diseases have shown that adherence is a major factor in outcomes and costs, there is scant research investigating adherence specifically in lymphoma patients, who face unique challenges in their diseases and treatments. To address the limited data available, we constructed a conceptual model and highlighted key opportunities for future research to better elucidate oral therapy adherence in lymphoma. This research will hopefully improve understanding and efficacy of oral treatment for lymphoma patients, while also informing other cancers utilizing oral therapies currently and in the future.

[PMID: 31208944 PMCID: PMC7036668 DOI: 10.1016/s2352-3026(19)30104-8] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2019] [Revised: 05/28/2019] [Accepted: 05/28/2019] [Indexed: 01/25/2023]
Abstract
BACKGROUND Fludarabine, cyclophosphamide, and rituximab (FCR) can improve disease-free survival for younger (age ≤65 years) fit patients with chronic lymphocytic leukaemia with mutated IGHV. However, patients with unmutated IGHV rarely have durable responses. Ibrutinib is active for patients with chronic lymphocytic leukaemia irrespective of IGHV mutation status but requires continuous treatment. We postulated that time-limited ibrutinib plus FCR would induce durable responses in younger fit patients with chronic lymphocytic leukaemia. METHODS We did a multicentre, open-label, non-randomised, single-arm phase 2 trial at seven sites in the USA. We enrolled patients aged 65 years or younger with previously untreated chronic lymphocytic leukaemia. Our initial cohort (original cohort) was not restricted by prognostic marker status and included patients who had del(17p) or TP53 aberrations. After a protocol amendment (on March 21, 2017), we enrolled an additional cohort (expansion cohort) that included patients without del(17p). Ibrutinib was given orally (420 mg/day) for 7 days, then up to six 28-day cycles were administered intravenously of fludarabine (25 mg/m2, days 1-3), cyclophosphamide (250 mg/m2, days 1-3), and rituximab (375 mg/m2 day 1 of cycle 1; 500 mg/m2 day 1 of cycles 2-6) with continuous oral ibrutinib (420 mg/day). Responders continued on ibrutinib maintenance for up to 2 years, and patients with undetectable minimal residual disease in bone marrow after 2 years were able to discontinue treatment. The primary endpoint was the proportion of patients who achieved a complete response with undetectable minimal residual disease in bone marrow 2 months after the last cycle of ibrutinib plus FCR. Analyses were done per-protocol in all patients who received at least one dose of study treatment. This trial is registered with ClinicalTrials.gov (NCT02251548) and is ongoing. FINDINGS Between Oct 23, 2014, and April 23, 2018, 85 patients with chronic lymphocytic leukaemia were enrolled. del(17p) was detected in four (5%) of 83 patients and TP53 mutations were noted in three (4%) of 81 patients; two patients had both del(17p) and TP53 mutations. Median patients' age was 55 years (IQR 50-58). At data cutoff, median follow-up was 16·5 months (IQR 10·6-34·1). A complete response and undetectable minimal residual disease in bone marrow 2 months after the last cycle of ibrutinib plus FCR was achieved by 28 (33%, 95% CI 0·23-0·44) of 85 patients (p=0·0035 compared with a 20% historical value with FCR alone). A best response of undetectable minimal residual disease in bone marrow was achieved by 71 (84%) of 85 patients during the study. One patient had disease progression and one patient died (sudden cardiac death after 17 months of ibrutinib maintenance, assessed as possibly related to ibrutinib). The most common all-grade toxic effects were haematological, including thrombocytopenia in 63 (74%) patients, neutropenia in 53 (62%), and anaemia in 41 (49%). Grade 3 or 4 non-haematological serious adverse events included grade 3 atrial fibrillation in three (4%) patients and grade 3 Pneumocystis jirovecii pneumonia in two (2%). INTERPRETATION The proportion of patients who achieved undetectable minimal residual disease in bone marrow with ibrutinib plus FCR is, to our knowledge, the highest ever published in patients with chronic lymphocytic leukaemia unrestricted by prognostic marker status. Ibrutinib plus FCR is promising as a time-limited combination regimen for frontline chronic lymphocytic leukaemia treatment in younger fit patients.

Abstract
Background Ibrutinib is a Bruton’s tyrosine-kinase (BTK) inhibitor that is approved as a second-line treatment in chronic lymphocytic leukemia (CLL). While recent trials have demonstrated impressive results for ibrutinib, there remains a paucity of real-world data on its use in the clinical setting. Methods In this single-center study carried out at Brighton and Sussex University Hospitals, we retrospectively compared outcomes in 38 patients with relapsed CLL who received ibrutinib versus those who received conventional first- and second-line therapies. Results Our results demonstrate improved progression-free survival (PFS, p=0.022) with ibrutinib versus conventional second-line therapies and survival comparable to conventional first-line therapies. However, there was a high frequency (81.6%) of adverse events associated with ibrutinib therapy, including 2 cases of death secondary to sepsis and a further 7 cases of discontinuation of treatment due to adverse events. We also identify del13q14.3 as an adverse predictor of response to ibrutinib with respect to both overall survival (p=0.014) and PFS (p=0.008), suggesting that these patients may be better suited to receiving the BCL2 inhibitor venetoclax. Conclusion Whilst there is robust evidence for improved outcomes with ibrutinib, we find that survival in patients with del13q14.3 is reduced and that the rate of adverse events and discontinuation in clinical practice is higher than anticipated from clinical trials.

Abstract
Chronic lymphocytic leukaemia (CLL) has long been thought to be an immunosuppressive disease and abnormalities in T-cell subset distribution and function have been observed in many studies. However, the role of T cells (if any) in disease progression remains unclear and has not been directly studied. This has changed with the advent of new therapies, such as chimeric antigen receptor-T cells, which actively use retargeted patient-derived T cells as "living drugs" for CLL. However complete responses are relatively low (~26%) and recent studies have suggested the differentiation status of patient T cells before therapy may influence efficacy. Non-chemotherapeutic drugs, such as idelalisib and ibrutinib, also have an impact on T cell populations in CLL patients. This review will highlight what is known about T cells in CLL during disease progression and after treatment, and discuss the prospects of using T cells as predictive biomarkers for immune status and response to therapy.

Abstract
We identified all patients with chronic lymphocytic leukemia at Mayo Clinic treated with ibrutinib outside the context of a clinical trial; timing and reasons for discontinuation were ascertained, as were symptoms, exam and radiographic findings, and laboratory changes following discontinuation. Of 202 patients who received ibrutinib, 52 discontinued therapy (estimated 1- and 2-year risk of discontinuation 18% and 28%, respectively). The most common reasons for discontinuation were toxicity (56%) and progression of disease (32%, including Richter's transformation in 15%). Rapid progression of disease within 4 weeks after discontinuation was observed in 9/36 (25%) patients with adequate records for review, mostly in those stopping ibrutinib for disease progression (n = 8) rather than toxicity (n = 1). This was evident by sudden worsening of disease-related symptoms (n = 9), exam/radiographic changes (n = 7), and laboratory changes (n = 8). An estimated one in every three patients discontinued ibrutinib by 2 years, with 25% developing rapid disease progression afterwards.

Abstract
Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in Western countries with an incidence of 3-5 cases per 100,000 persons. Most patients follow an indolent clinical course with eventual progression and need for therapy. In contrast, T-prolymphocytic leukemia (T-PLL) is a rare type of T-cell leukemia with most patients having an aggressive clinical course and a dismal prognosis. Therapies are limited for T-PLL patients and there is a high relapse rate. Morphologically, the cells of CLL and T-PLL can show overlapping features. Here, we report the case of a 61-year-old man who presented with a clinically indolent CLL and T-PLL, initially diagnosed solely and followed as CLL, despite the presence of an associated but unrecognized aberrant T-cell population in blood. After 2 years, the T-PLL component became more apparent with cutaneous and hematologic manifestations and the diagnosis was confirmed by immunophenotypic and cytogenetic analysis. Fluorescence in situ hybridization demonstrated an ATM deletion in both CLL and T-PLL components. Retrospective testing demonstrated that composite CLL and T-PLL were both present in skin and lymph nodes as well as in blood and bone marrow since initial presentation. This case is also unique because it highlights that a subset of T-PLL patients can present with clinically indolent disease. The concomitant detection of ATM mutation in CLL and T-PLL components raises the possibility of a common pathogenic mechanism.

Abstract
Chronic lymphocytic leukemia (CLL) therapy has changed dramatically with the introduction of several targeted therapeutics. Ibrutinib was the first approved for use in 2014 and now is used for initial and salvage therapy of CLL patients. With its widespread use in clinical practice, ibrutinib's common and uncommon adverse events reported less frequently in earlier clinical trials have been experienced more frequently in real-world practice. In particular, atrial fibrillation, bleeding, infections, and arthralgias have been reported. The management of ibrutinib's adverse events often cannot be generalized but must be individualized to the patient and their long-term risk of additional complications. When ibrutinib was initially developed, there were limited therapeutic alternatives for CLL, which often resulted in treating through the adverse events. At the present time, there are several effective alternative agents available, so transition to an alternative CLL directed therapy may be considered. Given the continued expansion of ibrutinib across many therapeutic areas, investigation of the pathogenesis of adverse events with this agent and also clinical trials examining therapeutic approaches for complications arising during therapy are needed. Herein, we provide strategies we use in real-world CLL clinical practice to address common adverse events associated with ibrutinib.

Abstract
Objective: To review the literature for the treatment of classical and variant hairy cell leukemia (HCL, HCLv), evaluating efficacy, safety, and supportive care involved in the use of purine analogues (PAs), interferon, BRAF inhibitors, monoclonal antibodies, Bruton's tyrosine kinase inhibitors, and new immunotoxin, moxetumomab pasudotox-tdfk (MPT). An electronic literature search of PubMed (January 1958 to January 2019) was conducted in PubMed using the MESH terms hairy cell leukemia, hairy cell leukemia variant, cladribine, pentostatin, rituximab, interferon, vemurafenib, moxetumomab pasudotox. Study Selection and Data Extraction: Studies written in the English language were considered for this article. The significance of each article was determined by authors independently. Data Synthesis: HCL and HCLv are rare B-cell lymphoproliferative disorders, each with distinct biologies. Symptoms are characterized by pancytopenia and splenomegaly. Initial treatments for HCL were suboptimal, leading to minimal and transient remissions. PAs significantly improved outcomes, inducing remission in most patients. However, those with purine-resistant disease were left with a dearth of options, leading to implementation of vemurafenib for BRAF V600 mutated disease and chemoimmunotherapy with rituximab. Despite these advances, some HCL and a majority of HCLv patients experience relapse. Newer targeted agents offer promise for relapsed and refractory patients, including the recently approved MPT. Relevance to Patient Care and Clinical Practice: This review provides a comprehensive update on the pharmacological management of HCL and HCLv for clinicians who encounter patients with this rare disease. Conclusion: HCL and HCLv are uncommon lymphoid neoplasms that lead to a characteristic constellation of symptoms. The emergence of PAs and novel targeted agents have improved the likelihood and durability of responses for these patients.

Relapsed/Refractory Chronic Lymphocytic Leukemia: Chemoimmunotherapy, Treatment until Progression with Mechanism-Driven Agents or Finite-Duration Therapy? Mediterr J Hematol Infect Dis 2019; 11:e2019024. [PMID: 30858962 PMCID: PMC6402553 DOI: 10.4084/mjhid.2019.024] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2019] [Accepted: 02/01/2019] [Indexed: 12/19/2022] Open
Abstract
Treatment of relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL) has dramatically improved thanks to the development of mechanism-driven agents including drugs that inhibit kinases in the BCR pathway or BCL2. The treating physician has now the opportunity to decide i) which patient can be still offered chemoimmunotherapy as salvage treatment, ii) which patient at relapse is a candidate to receiving, continuous treatment with ibrutinib, idelalisib and rituximab or venetoclax and iii) which patient may benefit from a fixed-duration treatment using the BCL2 antagonist venetoclax in association with rituximab. Ibrutinib is the most actively investigated drug in R/R CLL and data at a 7-year follow-up were reported, showing durable efficacy and favorable efficacy profile. The patients with cardiac disease, hypertension, and anticoagulant therapy are not ideal candidates for continuous therapy with this agent. Idelalisib and rituximab were tested in patients with unfavorable characteristics including cytopenias. The short follow-up and treatment-emergent adverse events limit its role to patients unlikely to get a benefit with other agents. Venetoclax and rituximab is the only effective chemo-free approach for the treatment of R/R with a fixed duration (up to 24 months) schedule capable of inducing deep responses in the majority of cases with a reassuring safety profile. While a deep knowledge of the growing body of scientific evidence is required to inform and guide the appropriate treatment choice and management, physicians cannot disregard the growing problem of sustainability.

Abstract
Ibrutinib, a Bruton tyrosine kinase inhibitor, is approved for treatment of various B-cell malignancies. In ibrutinib clinical studies, low-grade haemorrhage was common, whereas major haemorrhage (MH) was infrequent. We analysed the incidence of and risk factors for MH from 15 ibrutinib clinical studies (N = 1768), including 4 randomised controlled trials (RCTs). Rates of any-grade bleeding were similar for single-agent ibrutinib and ibrutinib combinations (39% and 40%). Low-grade bleeding was more common in ibrutinib-treated than comparator-treated patients (35% and 15%), and early low-grade bleeding was not associated with MH. The proportion of MH in RCTs was higher with ibrutinib than comparators (4.4% vs. 2.8%), but after adjusting for longer exposure with ibrutinib (median 13 months vs. 6 months), the incidence of MH was similar (3.2 vs. 3.1 per 1000 person-months). MH led to treatment discontinuation in 1% of all ibrutinib-treated patients. Use of anticoagulants and/or antiplatelets (AC/AP) during the study was common (~50% of patients) and had an increased exposure-adjusted relative risk for MH in both the total ibrutinib-treated population (1.9; 95% confidence interval, 1.2-3.0) and RCT comparator-treated patients (2.4; 95% confidence interval, 1.0-5.6), indicating that ibrutinib may not alter the effect of AC/AP on the risk of MH in B-cell malignancies.

Abstract
The treatment landscape for patients with chronic lymphocytic leukemia (CLL) has changed considerably with the introduction of very effective oral targeted therapies (such as ibrutinib, idelalisib, and venetoclax), and next-generation anti-CD20 monoclonal antibodies (such as obinutuzumab). These agents lead to improved outcomes in CLL, even among patients with high-risk features, such as del17p13 or TP53 mutation and unmutated immunoglobulin heavy chain (IGHV) genes. Each of these treatments is associated with a unique toxicity profile; in the absence of randomized data, the choice of one type of treatment over another depends on the co-morbidities of the patient. Chemoimmunotherapy still plays an important role in the management of previously untreated CLL patients, particularly among young fit patients who have standard risk FISH profile and mutated IGHV genes. Richter's transformation of CLL remains a difficult complication to treat, although therapy with programmed death 1 inhibitors such as pembrolizumab and nivolumab has shown impressive responses in a subset of patients. Our ability to risk stratify CLL patients continues to evolve; the CLL-International Prognostic Index (CLL-IPI) is the best validated tool in predicting time to first therapy among previously untreated patients. This review summarizes the current approach to risk stratification and management of CLL patients.

Abstract
INTRODUCTION In recent years, innovative mechanism-based drugs have enriched the therapeutic armamentarium for patients with chronic lymphocytic leukemia (CLL) and are widely used in the clinical practice. These small molecules targeting the B-cell receptor signaling pathway and the BCL-2 anti-apoptotic protein offer new chemo-free options to both unfit patients and high-risk patients who show a poor response to chemoimmunotherapy. Nonetheless, treatment with ibrutinib, idelalisib and venetoclax is associated with unique side effects. Awareness, prevention and the appropriate management of these specific toxicities are of crucial importance for a successful treatment. Areas covered: The purpose of this review is to discuss the most relevant studies on small molecules in CLL, with particular attention to the emerging toxicity profile of these agents and to the factors that should be considered to address the most appropriate treatment approach for each patient. Expert opinion: The increased knowledge on the biology of CLL has translated into the development of targeted agents that are highly effective and produce deep responses. Toxicities potentially associated with these agents should be known for an optimal management of CLL patients.

Abstract
The bloodstream typically contains >500 billion anucleate circulating platelets, derived from megakaryocytes in the bone marrow. This review will focus on two interesting aspects of bone marrow dysfunction and how this impacts on the quality of circulating platelets. In this regard, although megakaryocytes are from the myeloid lineage leading to granulocytes (including neutrophils), erythrocytes, and megakaryocytes/platelets, recent evidence has shown that defects in the lymphoid lineage leading to B cells, T cells, and natural killer (NK) cells also result in abnormal circulating platelets. Current evidence is limited regarding whether this latter phenomenon might potentially arise from (a) some form of as-yet-undetected defect common to both lineages; (b) adverse interactions occurring between cells of different lineages within the bone marrow environment; and/or (c) unknown disease-related factor(s) affecting circulating platelet receptor expression/function after their release from megakaryocytes. Understanding the mechanisms underlying how both myeloid and lymphoid lineage bone marrow defects lead to dysfunction of circulating platelets is significant because of the potential diagnostic and predictive value of peripheral platelet analysis for bone marrow disease progression, the additional potential effects of new anti-cancer drugs on platelet function, and the critical role platelets play in regulation of bleeding risk, inflammation, and innate immunity.

Abstract
The last 5 years have been marked by profound innovation in the targeted treatment of chronic lymphocytic leukemia (CLL) and indolent lymphomas. Using CLL as a case study, we present a timeline and overview of the current treatment landscape for the radiologist, including an overview of clinical and radiological features of CLL, discussion of the targeted agents themselves, and the role of imaging in response and toxicity assessment. The goal is to familiarize the radiologist with multiple Food and Drug Administration (FDA)-approved targeted agents used in this setting and associated adverse events which are commonly observed in this patient population.

Abstract
The Bruton tyrosine kinase inhibitor ibrutinib (IB) has attained an important role in the treatment of patients with chronic lymphocytic leukaemia, mantle cell lymphoma, and Waldenström macroglobulinemia, significantly improving clinical outcomes. However, IB therapy has been associated with an increased risk of atrial fibrillation (AF) and bleeding. We report on the expert opinion that a group of Italian haematologists, cardiologists, and pharmacologists jointly released to improve the practical management of patients at risk for AF and bleeding during treatment with IB. A proper pretreatment assessment to identify patients who are at a higher risk, careful choice of concomitant drugs, regular monitoring, and multispecialist approach were characterized as the main principles of clinical management of these patients. For patients developing AF, anticoagulant and antiarrhythmic therapy must be guided by considerations about efficacy, safety, and risk of pharmacokinetic interactions with IB. For patients experiencing bleeding or requiring procedures that increase the risk of bleeding, considerations about platelet turnover, IB-related platelet dysfunctions, and bleeding worsening by concomitant anticoagulants or antiplatelet agents provide clues to manage bleeding. Overall, AF and bleeding are manageable clinical events in patients receiving IB, not requiring drug interruption in most cases. Preexisting AF should not represent an absolute contraindication to IB therapy. For each patient candidate for IB, strategies of risk assessment and mitigation may allow to exploit the life-saving effects of in chronic lymphocytic leukaemia and mantle cell lymphoma.

Abstract
BACKGROUND The present review is part of the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) Study Group for Infections in Compromised Hosts (ESGICH) Consensus Document on the safety of targeted and biologic therapies. AIMS To review, from an infectious diseases perspective, the safety profile of therapies targeting different intracellular signaling pathways and to suggest preventive recommendations. SOURCES Computer-based Medline searches with MeSH terms pertaining to each agent or therapeutic family. CONTENT Although BCR-ABL tyrosine kinase inhibitors modestly increase the overall risk of infection, dasatinib has been associated with cytomegalovirus and hepatitis B virus reactivation. BRAF/MEK kinase inhibitors do not significantly affect infection susceptibility. The effect of Bruton tyrosine kinase inhibitors (ibrutinib) among patients with B-cell malignancies is difficult to distinguish from that of previous immunosuppression. However, cases of Pneumocystis jirovecii pneumonia (PCP), invasive fungal infection and progressive multifocal leukoencephalopathy have been occasionally reported. Because phosphatidylinositol-3-kinase inhibitors (idelalisib) may predispose to opportunistic infections, anti-Pneumocystis prophylaxis and prevention strategies for cytomegalovirus are recommended. No increased rates of infection have been observed with venetoclax (antiapoptotic protein Bcl-2 inhibitor). Therapy with Janus kinase inhibitors markedly increases the incidence of infection. Pretreatment screening for chronic hepatitis B virus and latent tuberculosis infection must be performed, and anti-Pneumocystis prophylaxis should be considered for patients with additional risk factors. Cancer patients receiving mTOR inhibitors face an increased incidence of overall infection, especially those with additional risk factors (prior therapies or delayed wound healing). IMPLICATIONS Specific preventive approaches are warranted in view of the increased risk of infection associated with some of the reviewed agents.

Abstract
Conventional treatments for acute leukemia include chemotherapy, radiation therapy, and intensive combined treatments (including bone marrow transplant or stem cell transplants). Novel treatment approaches are in active development. Recently, protein kinase inhibitors are on clinical trials and offer hope as new drugs for acute leukemia treatment. This review will provide a brief summary of the protein kinase inhibitors in clinical applications for acute leukemia treatment.
