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
OBJECTIVE This retrospective observational study aimed to compare healthcare resource utilization and costs of Medicare beneficiaries with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who received ibrutinib versus chemoimmunotherapy (CIT) in first line (1 L). METHODS Fee-for-service (FFS) and Medicare Advantage (MA) claims data were used to identify adults with a CLL/SLL diagnosis initiating 1 L ibrutinib single agent or CIT between 4 March 2016 and 30 September 2017 (index date). HRU and costs (Medicare spending) were evaluated during 1 L Oncology Care Model (1 L OCM) episodes (the first six months post-index) and over the observed 1 L duration. Patients' baseline characteristics were balanced using inverse probability of treatment weighting. Mean monthly cost differences (MMCDs) obtained from ordinary least square regressions were used to compare costs between ibrutinib and CIT cohorts. RESULTS In the Medicare FFS dataset (ibrutinib: n = 2014; CIT: n = 2050), ibrutinib patients incurred significantly higher monthly pharmacy costs (1 L OCM: MMCD = $4878, p < .0001; 1 L duration: MMCD= $4892, p < .0001) that were fully offset by lower monthly medical costs (1 L OCM: MMCD= -$8289, p < .0001; 1 L duration: MMCD=-$5888, p < .0001), yielding a monthly total healthcare cost reduction (1 L OCM: MMCD=-$3411, p < .0001; 1 L duration: MMCD=-$996, p < .0001) relative to CIT patients. In the MA dataset (ibrutinib: n = 293; CIT: n = 303), ibrutinib was also associated with a monthly total healthcare cost reduction (1 L OCM: MMCD=-$10,459; 1 L duration: MMCD=-$5492). CONCLUSIONS In Medicare patients with CLL/SLL, 1 L ibrutinib single agent was associated with total monthly cost savings relative to 1 L CIT, driven by lower monthly medical costs that fully offset higher monthly pharmacy costs.

Abstract
Venetoclax – a novel, orally bioavailable inhibitor of B-cell lymphoma-2 – has demonstrated substantial clinical activity in the treatment of chronic lymphocytic leukemia. Alone or in combination with other targeted agents, venetoclax results in high rate of durable responses and undetectable measurable residual disease. The peculiarity of venetoclax is that it allows for fixed durations of therapy of 12 months in the frontline and 24 months in the relapsed/refractory setting, with a favorable impact on compliance and pharmacoeconomics. This approach implies a change of therapeutic paradigm in chronic lymphocytic leukemia from continuous to time-fixed therapy. Nowadays, it remains challenging to identify patients suitable for the optimal approach. Clinical trials addressing the issue of continuous versus time-limited therapy are ongoing.

Abstract
Bruton’s tyrosine kinase (BTK) inhibitor is a promising novel agent that has potential efficiency in B-cell malignancies. It took approximately 20 years from target discovery to new drug approval. The first-in-class drug ibrutinib creates possibilities for an era of chemotherapy-free management of B-cell malignancies, and it is so popular that gross sales have rapidly grown to more than 230 billion dollars in just 6 years, with annual sales exceeding 80 billion dollars; it also became one of the five top-selling medicines in the world. Numerous clinical trials of BTK inhibitors in cancers were initiated in the last decade, and ~73 trials were intensively announced or updated with extended follow-up data in the most recent 3 years. In this review, we summarized the significant milestones in the preclinical discovery and clinical development of BTK inhibitors to better understand the clinical and commercial potential as well as the directions being taken. Furthermore, it also contributes impactful lessons regarding the discovery and development of other novel therapies.

Abstract
Cardiotoxicity is the umbrella term for cardiovascular side effects of cancer therapies. The most widely recognized phenotype is left ventricular dysfunction, but cardiotoxicity can manifest as arrhythmogenic, vascular, myocarditic and hypertensive toxicities. Hypertension has long been regarded as one of the most prevalent and modifiable cardiovascular risk factors in the general population, but its relevance during the cancer treatment journey may be underestimated. Hypertensive cardiotoxicity occurs de novo in a substantial proportion of treated cancer patients. The pathology is incompletely characterized—natriuresis and renin angiotensin system interactions play a role particularly in conventional treatments, but in novel therapies endothelial dysfunction and the interaction between the cancer and cardiac kinome are implicated. There exists a treatment paradox in that a significant hypertensive response not only mandates anti-hypertensive treatment, but in fact, in certain cancer treatment scenarios, hypertension is a predictor of cancer treatment efficacy and response. In this comprehensive review of over 80,000 patients, we explored the epidemiology, incidence, and mechanistic pathophysiology of hypertensive cardiotoxicity in adjunct, conventional chemotherapy, and novel cancer treatments. Conventional chemotherapy, adjunct treatments, and novel targeted therapies collectively caused new onset hypertension in 33–68% of treated patients. The incidence of hypertensive cardiotoxicity across twenty common novel therapies for any grade hypertension ranged from 4% (imatinib) to 68% (lenvatinib), and high grade 3 or 4 hypertension in <1% (imatinib) to 42% (lenvatinib). The weighted average effect was all-grade hypertension in 24% and grade 3 or 4 hypertension in 8%.

Abstract
BACKGROUND Platelets have critical roles in preventing blood loss following injury, promoting wound healing, and in fighting infection through innate immune defense strategies. KEY RESULTS Deficiencies in platelet number or function either as a result of disease, as a consequence of therapy, or both can lead to dramatic and potentially fatal consequences. CONCLUSIONS AND INFERENCES With the advent of new therapeutics targeting pathways within hematological malignant cells that are also important for platelet function, monitoring the state of a patient's haemostasis system is now an important clinical consideration.

Abstract
BACKGROUND Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) is the most common adult leukemia, accounting for ≈ 37% of all leukemias in the United States. Limited real-word evidence is available on the outcomes of ibrutinib use among previously untreated patients in the U.S. Veterans Health Administration (VHA) population diagnosed with CLL/SLL. OBJECTIVES To (a) evaluate time to next treatment (TTNT) among U.S. veterans with CLL/SLL who initiated ibrutinib versus chemoimmunotherapy (CIT) in first line (1L) and 1L ibrutinib versus ibrutinib in later lines (2L+) and (b) compare health care resource utilization (HRU) and costs between the 1L ibrutinib and CIT cohorts. METHODS Adults with CLL/SLL and claims for 1L single-agent ibrutinib or CIT (index date = first prescription claim date) were included from Veterans Health Administration Data (April 1, 2013-March 31, 2018). A subset of the CIT 1L cohort with evidence of ibrutinib in 2L/3L was defined as the ibrutinib 2L+ cohort. Kaplan-Meier curves and Cox proportional hazard models were used to evaluate TTNT, and generalized linear models were used to determine all-cause per patient per month (PPPM) HRU and costs during 1L among propensity score-matched (PSM) cohorts. RESULTS After PSM, 614 patients were included in each of the 1L ibrutinib and 1L CIT cohorts, and 149 were included in each of the 1L ibrutinib and 2L+ ibrutinib cohorts. The 1L ibrutinib cohort had significantly longer TTNT compared with each of the 1L CIT and 2L+ ibrutinib cohorts (P <0.0001 and P =0.0001, respectively) and was less likely to have a next line of treatment than the CIT 1L cohort (HR = 0.52; 95% CI = 0.42-0.65; P < 0.0001) and the 2L+ ibrutinib cohort (HR = 0.39; 95% CI = 0.22-0.69; P = 0.0012). The 1L ibrutinib cohort had significantly fewer inpatient visits (rate ratio [RR] = 0.38; 95% CI = 0.28-0.52; P ≤ 0.05) and outpatient visits PPPM (RR =0.72; 95% CI = 0.68-0.77; P ≤ 0.5) compared with the CIT 1L cohort. Additionally, the 1L ibrutinib cohort had $7,308 significantly lower monthly medical costs (95% CI = -$9,892 to -$4,895; P ≤ 0.05) versus the 1L CIT cohort, resulting in comparable monthly total health care cost (medical and pharmacy) between real-world 1L patients treated by ibrutinib and CIT (-$2,160; 95% CI = -$4,840-$347; P > 0.05). CONCLUSIONS These findings demonstrate that among U.S. veterans with CLL/SLL, 1L ibrutinib use was associated with significantly longer TTNT versus that of 1L CIT. Similarly, early treatment with ibrutinib was associated with longer TTNT as compared to ibrutinib use in later lines of therapy. Moreover, 1L ibrutinib was associated with lower HRU and medical costs compared with 1L CIT, completely offsetting the higher pharmacy costs related to 1L ibrutinib treatment.

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
Bruton tyrosine kinase (BTK) is a nonreceptor tyrosine kinase that plays a central role in the signal transduction of the B-cell antigen receptor and other cell surface receptors, both in normal and malignant B lymphocytes. B-cell antigen receptor signaling is activated in secondary lymphatic organs and drives the proliferation of malignant B cells, including chronic lymphocytic leukemia (CLL) cells. During the last 10 years, BTK inhibitors (BTKis) are increasingly replacing chemotherapy-based regimen, especially in patients with CLL and mantle cell lymphoma (MCL). Bruton tyrosine kinase inhibitors are particularly active in patients with CLL and MCL, but also received approval for Waldenström macroglobulinemia, small lymphocytic lymphoma, marginal zone lymphoma, and chronic graft-versus-host disease. Current clinical practice is continuous long-term administration of BTKi, which can be complicated by adverse effects or the development of drug resistance. Alternatives to long-term use of BTKi are being developed, such as combination therapies, permitting for limited duration therapy. Second-generation BTKis are under development, which differ from ibrutinib, the first-in-class BTKi, in their specificity for BTK, and therefore may differentiate themselves from ibrutinib in terms of adverse effects or efficacy.

Ibrutinib restores immune cell numbers and function in first-line and relapsed/refractory chronic lymphocytic leukemia. Leuk Res 2020; 97:106432. [PMID: 32911375 DOI: 10.1016/j.leukres.2020.106432] [Citation(s) in RCA: 38] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Revised: 08/04/2020] [Accepted: 08/06/2020] [Indexed: 12/14/2022]
Abstract
Ibrutinib positively modulates many T-cell subsets in chronic lymphocytic leukemia (CLL). To understand ibrutinib's effects on the broader landscape of immune cell populations, we comprehensively characterized changes in circulating counts of 21 immune blood cell subsets throughout the first year of treatment in patients with relapsed/refractory (R/R) CLL (n = 55, RESONATE) and previously untreated CLL (n = 50, RESONATE-2) compared with untreated age-matched healthy donors (n = 20). Ibrutinib normalized abnormal immune cell counts to levels similar to those of age-matched healthy donors. Ibrutinib significantly decreased pathologically high circulating B cells, regulatory T cells, effector/memory CD4+ and CD8+ T cells (including exhausted and chronically activated T cells), natural killer (NK) T cells, and myeloid-derived suppressor cells; preserved naive T cells and NK cells; and increased circulating classical monocytes. T-cell function was assessed in response to T-cell receptor stimulation in patients with R/R CLL (n = 21) compared with age-matched healthy donors (n = 18). Ibrutinib significantly restored T-cell proliferative ability, degranulation, and cytokine secretion. Over the same period, ofatumumab or chlorambucil did not confer the same spectrum of normalization as ibrutinib in multiple immune subsets. These results establish that ibrutinib has a significant and likely positive impact on circulating malignant and nonmalignant immune cells and restores healthy T-cell function.

Abstract
The peripheral nervous system may be involved at any stage in the course of several hematological diseases, the most common being monoclonal gammopathies (of undetermined significance or malignant) or lymphomas. The underlying pathogenic mechanisms are different and therapies aim at targeting the dangerous either B-cell or plasma cell clones. Recently, high-throughput technologies, and next-generation sequencing have increased our knowledge of hematological diseases pathogenesis by the identification of somatic mutation affecting pivotal signaling pathways. Accordingly, new target therapies are used that may also be borrowed for treatment of neuropathies in hematological diseases.

Abstract
We report final analysis outcomes from the phase 3 HELIOS study (NCT01611090). Patients with relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma without deletion 17p (n = 578) were randomized 1:1 to 420 mg daily ibrutinib or placebo plus ≤6 cycles of bendamustine plus rituximab (BR), followed by ibrutinib or placebo alone. Median follow-up was 63.7 months. Median investigator-assessed progression-free survival was longer with ibrutinib plus BR (65.1 months) than placebo plus BR (14.3 months; hazard ratio [HR] 0.229 [95% confidence interval (CI) 0.183–0.286]; p < .0001). Despite crossover of 63.3% of patients from the placebo plus BR arm to ibrutinib treatment upon disease progression, ibrutinib plus BR versus placebo plus BR demonstrated an overall survival benefit (HR 0.611 [95% CI 0.455–0.822]; p = 0010; median not reached in either arm). Long-term follow-up data confirm the survival benefit of ibrutinib plus BR over BR alone. Safety profiles were consistent with those known for ibrutinib and BR.

Abstract
Infections are a major cause of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL). These can be exacerbated by anti-leukemic treatments. In addition, the typical patients with CLL already have fragilities and background risk factors that apply to the general population for severe COVID-19. On these bases, patients with CLL may experience COVID-19 morbidity and mortality. Recurrent seasonal epidemics of SARS-CoV-2 are expected, and doctors taking care of patients with CLL must be prepared for the possibility of substantial resurgences of infection and adapt their approach to CLL management accordingly. In this Guideline Article, we aim at providing clinicians with a literature-informed expert opinion on the management of patients with CLL during SARS-CoV-2 epidemic.

Abstract
INTRODUCTION Patients with TP53 dysfunction, assessed by del(17p) or TP53 mutations, respond poorly to chemo-immunotherapy and fare better with the new therapies (BCR and BCL-2 inhibitors); however, it is unclear whether their response is similar to that of patients without anomalies or whether there is currently an adequate determination of TP53 dysfunction. AREA COVERED A literature search was undertaken on clinical trials and real-world experience data on patients with TP53 dysfunction treated with different protocols. Moreover, data on the TP53 biological function and on the tests currently employed for its assessment were reviewed. EXPERT OPINION Although TP53 dysfunction has less negative influence on the new biological therapies, patients with these alterations, particularly those with biallelic inactivation of TP53, have a worst outcome with these therapies than those without alterations. At present, a determination of TP53, particularly with next generation sequencing (NGS) methodologies, may be sufficient for the identifications of the patients unsuitable for chemo-immunotherapy, although integration with del(17p) would be advisable. For the future, more extensive determinations of the TP53 status, including functional assays, may become part of the current armamentarium for a better patient stratification and treatment with newer protocols.

Abstract
INTRODUCTION Chronic lymphocytic leukemia (CLL) is the most common leukemia in Western countries occurring typically in elderly patients. These patients often present with comorbidities limiting treatment options. During the last decade, the treatment paradigm has rapidly changed with the introduction of novel oral targeted agents and monoclonal antibodies. AREAS COVERED The review focuses on the combination of type II antiCD20 antibody obinutuzumab in combination with chemotherapy or oral targeted agents in patients not suited for fludarabine-based therapy because of comorbidities or age. The main focus of the review is whether classical immunochemotherapy with obinutuzumab-chlorambucil is still a valid therapeutic option or whether the combination of obinutuzumab and ibrutinib or venetoclax presents novel standard of care. EXPERT OPINION Both pivotal and registrational studies iLLLUMINATE study testing the combination of ibrutinib and obinutuzumab and CLL14 study testing the fixed combination of venetoclax and obinutuzumab have shown major benefit over chemoimmunotherapy approach in this population. Furthermore, they have excellent activity in high-risk subgroups of CLL paving the road toward a chemo-free immunotherapy approach in this setting. However, there are some pitfalls in these strategies warranting further research.

Abstract
Bruton’s tyrosine kinase (BTK), a pivotal component of B-cell receptor (BCR) signaling, has been recognized as an important driver of the pathogenesis of chronic lymphocytic leukemia. Ibrutinib is a highly active and selectively irreversible inhibitor of BTK, which has been approved to be effective in both frontline and recurrent therapy of CLL. Acquired resistance has become a greater problem than initially anticipated with the widespread use of ibrutinib. An ongoing exploration of the mechanisms of ibrutinib resistance (IR) in CLL has revealed potentially useful therapeutic targets. New drugs expected to overcome IR in CLL are in the early stages of clinical development. This study aimed to summarize the possible mechanisms of IR and retrospectively analyze promising therapies that might have superior efficacy in overcoming IR.

Abstract
Targeted agents have significantly improved outcomes for patients with chronic lymphocytic leukemia, particularly high-risk subgroups for whom chemoimmunotherapy previously offered limited efficacy. Two classes of agent in particular, the Bruton tyrosine kinase inhibitors (e.g., ibrutinib) and the B-cell lymphoma 2 inhibitor, venetoclax, induce high response rates and durable remissions in the relapsed/refractory and frontline settings. However, maturing clinical data have revealed promises and pitfalls for both agents. These drugs induce remissions and disease control in the majority of patients, often in situations where modest efficacy would be expected with traditional chemoimmunotherapy approaches. Unfortunately, in the relapsed and refractory setting, both agents appear to be associated with an inevitable risk of disease relapse and progression. Emerging patterns of resistance are being described for both agents but a common theme appears to be multiple sub-clonal drivers of disease progression. Understanding these mechanisms and developing effective and safe methods to circumvent the emergence of resistance will determine the longer-term utility of these agents to improve patients' quality and length of life. Rational drug combinations, optimised scheduling and sequencing of therapy will likely hold the key to achieving these important goals.

Abstract
Treatment standards for chronic lymphocytic leukemia (CLL) have been transformed with the advent of effective inhibitors of B-cell receptor signaling such as ibrutinib - a first-in-class inhibitor of BTK. Off-target kinase inhibitions by ibrutinib are thought to contribute to its adverse events. Zanubrutinib is a next-generation BTK inhibitor with minimal off-target effects, sustained BTK occupancy in peripheral blood mononuclear cells and lymph nodes from patients with B-cell malignancies and promising responses in patients with CLL. Described here is a head-to-head Phase III study comparing the efficacy and safety of zanubrutinib with those of ibrutinib in patients with CLL/small lymphocytic lymphoma in the relapsed/refractory setting.

Abstract
OPINION STATEMENT Treatment landscape of chronic lymphocytic leukemia (CLL) has changed since 2014 after the introduction of inhibitors of B-cell receptor signaling pathway (ibrutinib, acalabrutinib, idelalisib and duvelisib) and the inhibitor of the anti-apoptotic protein BCL-2 (venetoclax). In 2019, novel agents were upgraded from being a "great treatment option" to the "preferred choice" for all lines of treatment after number of randomized clinical trials proved their superiority compared to conventional chemoimmunotherapy (CIT) regimens. A growing number of next-generation molecules are in clinical trials with a promise of improved efficacy and less toxicity. This includes agents with expected better safety profile (zanubrutinib, umbralisib, etc.) or more importantly with a potential to overcome the resistance mechanism to early generation agents (ARQ-531, LOXO-305, or vecabrutinib). Early intervention has once again become an active topic of research and, if proven to provide an overall survival benefit, will eliminate the "watch and wait" strategy for asymptomatic CLL patients. Until then, treatment should only be offered to patients who meet the standard treatment indication in standard practice. With our upgraded therapeutic toolbox, there are and will be many unanswered questions. CLL field will need to define the optimal treatment sequence and most effective combinations with a goal of having a time-limited and chemotherapy-free regimen that provides longest remissions and potentially cure. Cellular immunotherapy with chimeric antigen receptor T-cell (CAR-T) may become available for high-risk CLL along with allogeneic stem cell transplant (allo-SCT). Financial toxicity of novel agents especially when used in combination will need to be an important aspect of research in coming years to avoid unnecessary overtreatment of patients. As current prognostic models (CLL-IPI, etc.) were developed and validated in the CIT era, there is ongoing effort to develop new models using clinical and molecular characteristics to accurately define high-risk CLL in the era of novel agents. We all need to keep in mind that access to the novel agents is currently limited to certain developed countries and every effort should be made to make sure patients around the world also benefit from these outstanding drugs.

Abstract
Fludarabine, cyclophosphamide and rituximab (FCR) was compared to bendamustine and rituximab (BR) in an international, randomized, open label, phase 3 trial in 561 previously untreated, fit patients with chronic lymphocytic leukemia (CLL) without del (17p). Primary endpoint was progression free survival (PFS). The final primary endpoint analysis after 37.1 months median follow up failed to show the non-inferiority of BR as compared with FCR. With extended median follow up of 58.2 months, median PFS was 42.3 months in BR-treated patients versus 57.6 months for FCR-treated patients (Hazard Ratio [HR] 1.593; 95% CI 1.271-1.996; p < 0.0001). For patients > 65 years, median PFS was 48.5 months with BR versus 57.9 months with FCR without reaching statistical significance (HR 1.352; 95% CI 0.912-2.006; p = 0.134). Median OS was not reached for both arms with 5-year OS rates of 80.1% vs 80.9%, respectively (HR 1.108; 95% CI 0.755-1.627; p = 0.599). No statistically significant difference was found in the time to secondary malignancy between the 2 groups (at 5 years, 86.6% free from secondary malignancies in the BR group vs 83.8% in the FCR group [HR 0.801; 95% CI 0.507-1.267; p = 0.344]). In patients >65 years secondary neoplasia occurred more frequently after FCR treatment [28 of 86 (32.6%) patients] as compared with BR [18 of 107 (16.8%) patients; p = 0.011]. Health-related quality of life was similar in both treatments. Despite the improved PFS for FCR, OS did not differ. These results also suggest an increase in secondary neoplasia associated with FCR in elderly fit CLL patients.

Abstract
A major revolution in the treatment of chronic lymphocytic leukemia (CLL) began with the approval of ibrutinib, a first-in-class oral inhibitor of Bruton tyrosine kinase (BTK), for the treatment of relapsed/refractory (R/R) and/or TP53 mutated patients with CLL. However, 5 years later, some issues relating to this disorder still remain including the fact that with ibrutinib only a relatively small proportion of patients achieve complete remission and that ibrutinib-resistant CLL clones can develop in about 20% of patients. In addition, therapy must still be given continuously, and toxicities leading to drug discontinuation occur in about 30% of patients. In the meantime second-generation BTK inhibitors have already aroused considerable interest and gathered momentum. A possible strategy to overcome some of these obstacles is to combine ibrutinib with other targeted agents especially in high-risk disease, such as previously treated refractory patients or those with TP53 aberrations or complex karyotypes, in whom rapid eradication of disease is most desirable. Therapy with single agent ibrutinib should be part of a sequential approach for patients with low risk disease, especially in older patients (aged >70 years) with a higher burden of comorbidities. Long-term results of ongoing studies combining Ibrutinib with (chemo)-immunotherapy or other targeted agents are eagerly awaited. Future clinical trials are indeed still needed to provide answers to these open questions.

Abstract
Ibrutinib, a once-daily oral inhibitor of Bruton's tyrosine kinase, is approved in the United States and Europe for treatment of patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The phase 3 RESONATE study showed improved efficacy of single-agent ibrutinib over ofatumumab in patients with relapsed/refractory CLL/SLL, including those with high-risk features. Here we report the final analysis from RESONATE with median follow-up on study of 65.3 months (range, 0.3-71.6) in the ibrutinib arm. Median progression-free survival (PFS) remained significantly longer for patients randomized to ibrutinib vs ofatumumab (44.1 vs 8.1 months; hazard ratio [HR]: 0.148; 95% confidence interval [CI]: 0.113-0.196; P˂.001). The PFS benefit with ibrutinib vs ofatumumab was preserved in the genomic high-risk population with del(17p), TP53 mutation, del(11q), and/or unmutated IGHV status (median PFS 44.1 vs 8.0 months; HR: 0.110; 95% CI: 0.080-0.152), which represented 82% of patients. Overall response rate with ibrutinib was 91% (complete response/complete response with incomplete bone marrow recovery, 11%). Overall survival, censored for crossover, was better with ibrutinib than ofatumumab (HR: 0.639; 95% CI: 0.418-0.975). With up to 71 months (median 41 months) of ibrutinib therapy, the safety profile remained consistent with prior reports; cumulatively, all-grade (grade ≥3) hypertension and atrial fibrillation occurred in 21% (9%) and 12% (6%) of patients, respectively. Only 16% discontinued ibrutinib because of adverse events (AEs). These long-term results confirm the robust efficacy of ibrutinib in relapsed/refractory CLL/SLL irrespective of high-risk clinical or genomic features, with no unexpected AEs. This trial is registered at www.clinicaltrials.gov (NCT01578707).
