Benkhadra M, Fituri N, Aboukhalaf S, Ghasoub R, Mattar M, Alfarsi K, Alshemmari S, Yassin MA. The Safety of Novel Therapies in Chronic Lymphocytic Leukemia in the Era of Intermittent Fasting: A Pharmacology-Based Review. Cancers (Basel) 2024; 16:2079. [PMID: 38893198 PMCID: PMC11171109 DOI: 10.3390/cancers16112079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 12/21/2023] [Accepted: 12/22/2023] [Indexed: 06/21/2024] Open
Abstract
Intermittent fasting (IF) has recently gained popularity due to its emerging benefits in reducing weight and improving metabolic health. Concurrently, novel agents (NAs) like venetoclax and Bruton tyrosine kinase inhibitors (BTKIs) have revolutionized the treatment of chronic lymphocytic leukemia (CLL). Unfortunately, it is unclear whether the associated risks of tumor lysis syndrome (TLS) and gastrointestinal bleeding (GIB) are increased in IF practitioners receiving NAs. This review explored the literature available on the permissibility of IF in CLL patients undergoing treatment with first-line NAs (FLNAs). Literature was scoped to identify IF patterns and the available data on TLS and GIB risks associated with food and fluid intake in CLL patients receiving FLNAs. Although current evidence is insufficient to recommend IF in this population, it may be possible for patients on venetoclax to conservatively practice fluid-liberal IF, provided that adequate hydration and the consistent administration of food are achieved. In contrast, considering the significant risk of TLS and the pharmacokinetics of venetoclax, patients should be discouraged from practicing fluid-restricted IF, especially during the ramp-up phase. Moreover, patients on BTKIs ought to refrain from IF due to the possible risk of GIB until further data are available. Further research is needed to provide conclusive recommendations.

Conditional survival to assess prognosis in patients with chronic lymphocytic leukemia. Ann Hematol 2024; 103:1613-1622.

Abstract
Biomarkers in chronic lymphocytic leukemia (CLL) allow assessment of prognosis. However, the validity of current prognostic biomarkers based on a single assessment point remains unclear for patients who have survived one or more years. Conditional survival (CS) studies that address how prognosis may change over time, especially in prognostic subgroups, are still rare. We performed CS analyses to estimate 5-year survival in 1-year increments, stratified by baseline disease characteristics and known risk factors in two community-based cohorts of CLL patients (Freiburg University Hospital (n = 316) and Augsburg University Hospital (n = 564)) diagnosed between 1984 and 2021. We demonstrate that 5-year CS probability is stable (app. 75%) for the entire CLL patient cohort over 10 years. While age, sex, and stage have no significant impact on CS, patients with high-risk disease features such as non-mutated IGHV, deletion 17p, and high-risk CLL-IPI have a significantly worse prognosis at diagnosis, and 5-year CS steadily decreases with each additional year survived. Our results confirm that CLL patients have a stable survival probability with excess mortality and that the prognosis of high-risk CLL patients declines over time. We infer that CS-based prognostic information is relevant for disease management and counseling of CLL patients.

Abstract
BACKGROUND Most of the predictive tools put up to prognosticate treatment outcomes in patients with chronic lymphocytic leukaemia (CLL) are not easily available and affordable in our resource-constrained environment. AIM The aim of this study was to evaluate the impact of staging and some tumour bulk on treatment outcomes of persons with CLL, Enugu, Nigeria. PATIENTS AND METHODS This is a 10-year review of the CLL data from the haemato-oncology unit of a Nigerian tertiary hospital to evaluate the impact of staging and tumour bulk indicators. Data were retrieved from the case notes of 102 patients with CLL receiving care at the facility. Data of interest include basic demographic variables, clinical features including spleen size and disease staging and blood counts. Statistical analysis was done using SPSS version 22. RESULTS The median absolute lymphocyte count (ALC) was 108.05 (confidence interval [CI] = 50.8-201.3, interquartile range [IQR] = 124.4) ×109/L, and duration of survival for the study cohort was 5.5 (CI = 3.5-31.9, IQR = 27) months. Majority (69, 79.3%) were in Stage C. The Binet stage showed a significant association with the ALC (r = 0.338; P = 0.002) but not with spleen size (r = 0.198; P = 0.056). The duration of survival only showed a significant inverse relationship with the ALC (r = 0.35, P = 0.006) but with neither the Binet stage (r = 0.103, P = 0.431) nor spleen size (r = 0.184, P = 0.116). CONCLUSION In CLL patients, ALC at presentation correlates with the duration of survival. We recommend that the ALC at presentation be used as a prognostic marker in our clime.

Abstract
Ofatumumab's therapeutic impact on patients with chronic lymphocytic leukemia (CLL) has been the subject of increasing clinical research. However, in recent years, no studies have yet provided a pooled assessment of the treatment effect of ofatumumab vs. non-ofatumumab regimens. Therefore, we conducted a progression meta-analysis to evaluate the efficacy of ofatumumab-based treatment in CLL patients using data from clinical studies. Relevant publications from PubMed, Web of Science and ClinicalTrials.gov were searched. The efficacy outcomes were progression-free survival (PFS) and overall survival (OS). The articles reviewed in the mentioned databases and matching the specified keywords were searched until January 2023. The pooled efficacy analysis showed that there was a significant difference in PFS [hazard ratios (HR) = 0.62, 95% confidence interval (CI) = 0.52-0.74] and no significant difference in OS (HR = 0.86, 95% CI = 0.71-1.03) between ofatumumab-based therapy and non-ofatumumab therapy. Our analysis showed the pooled efficacy for PFS was statistically significantly improved with ofatumumab-based treatments for CLL compared with other groups. Also, ofatumumab had no statistically significant improvement in the OS of patients with CLL. Thus, ofatumumab-based therapies for CLL patients could be improved by other combinational-based regimens.

Clinical and laboratory characteristics of patients with symptomatic secondary immunodeficiency following the treatment of haematological malignancies. EJHAEM 2023; 4:339-349.

Abstract
Secondary immunodeficiency (SID), manifesting as increased susceptibility to infection, is an emergent clinical problem in haematoncology. Management of SID includes vaccination, prophylactic antibiotics (pAbx) and immunoglobulin replacement therapy (IgRT). We report clinical and laboratory parameters of 75 individuals, treated for haematological malignancy, who were referred for immunological assessment due to recurrent infections. Forty-five were managed with pAbx while thirty required IgRT after failing to improve on pAbx. Individuals requiring IgRT had significantly more bacterial, viral and fungal infections resulting in hospitalization at least 5 years after their original haemato-oncological diagnosis. Following immunological assessment and intervention, a 4.39-fold reduction in the frequency of hospital admissions to treat infection was observed in the IgRT cohort and a 2.30-fold reduction in the pAbx cohort. Significant reductions in outpatient antibiotic use were also observed in both cohorts following immunology input. Patients requiring IgRT were more hypogammaglobulinaemic and had lower titres of pathogen-specific antibodies and smaller memory B cell populations than those requiring pAbx. Test vaccination with pneumococcal conjugate vaccine discriminated poorly between the two groups. Patients requiring IgRT could be distinguished by combining wider pathogen-specific serology with a frequency of hospital admissions for infection. If validated in larger cohorts, this approach may circumvent the need for test vaccination and enhance patient selection for IgRT.

Comparative Clinical Value of Pharmacologic Therapies for B-Cell Chronic Lymphocytic Leukemia: An Umbrella Analysis. J Clin Med 2022; 11:jcm11071868. [PMID: 35407474 PMCID: PMC8999707 DOI: 10.3390/jcm11071868] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 03/21/2022] [Accepted: 03/23/2022] [Indexed: 12/04/2022] Open
Abstract
Several new drugs are progressively improving the life span of patients with B-cell chronic lymphocytic leukemia (CLL). However, the rapidly evolving standard of care precludes robust assessments of the incremental clinical value of further innovative drugs. Therefore, we systematically reviewed comparative evidence on newly authorized CLL drugs, as reported by standard and network meta-analyses (MA) published since 2016. Overall, 17 MAs addressed the relative survival or safety of naïve and/or refractory/relapsed (R/R) CLL patients. In R/R patients, therapies including BTK- and BCL2-inhibitors reported progression free survival (PFS) hazard ratios ranging from 0.08 to 0.24 (versus chemotherapy) and a significant advantage in overall survival (OS). In naïve patients, the PFS hazard ratios associated with four recent chemo-free therapies (obinutuzumab- and/or acalabrutinib-based) ranged from 0.11 to 0.61 versus current standard treatments (STs), without a significant OS advantage. Ten MAs addressed the risk of cardiovascular, bleeding, and infective events associated with BTK inhibitors, with some reporting a different relative safety in naïve and R/R patients. In conclusion, last-generation therapies for CLL consistently increase PFS, but not OS, and minimally decrease safety, as compared with STs. Based on available evidence, the patient-customized adoption of new therapies, rather than universal recommendations, seems desirable in CLL patients.

Abstract
Selecting the most appropriate chronic lymphocytic leukaemia (CLL) treatment is challenging. Patient-reported health-related quality of life (HRQoL) is therefore a critical aspect to consider. This international study by the European Organization for Research and Treatment of Cancer (EORTC) tested the psychometric properties of a newly developed measure for CLL patients: the EORTC QLQ-CLL17 to supplement the core questionnaire (EORTC QLQ-C30). Patients with CLL (n = 341) from 12 countries completed the QLQ-C30, QLQ-CLL17 and a debriefing questionnaire. Sociodemographic and clinical data were recorded from medical records. A high percentage (30%-66%) reported symptoms and/or worries (e.g. aches/pains in muscles, lack of energy and worry/fears about health). Confirmatory factor analysis showed an acceptable to good fit of the 17 items on the three scales (i.e. symptom burden, physical condition/fatigue and worries/fears about health and functioning). Completion took on average 8 min. Test-retest and convergent validity was demonstrated. The QLQ-CLL17 differentiated between patients with an Eastern Cooperative Oncology group (ECOG) performance of 0 versus 1-3 (p's < 0.01 and clinically relevant). The newly developed EORTC QLQ-CLL17 will increase sensitivity of HRQoL assessment in patients with CLL. Implementation of this questionnaire both in clinical research and practice will help to generate unique clinically relevant data to better inform CLL treatment decision-making.

Abstract
The study aim was to analyze incidence and presentation features of chronic lymphocytic leukemia (CLL) in Chile, in Amerindian population and in non-Native. Between 2012 and 2019, 912 patients were diagnosed, and 13 (1.4%) were Amerindian. The estimated incidence in Chilean population was 1.17/100,000 person per year, while in Amerindian, 0.09/100,000 person per year. Median age was 73 years. At diagnosis, 48, 27, and 25%, had low (0), intermediate (I/II) and high-risk (III/IV) disease on Rai classification. Diagnostic immunophenotypic Matutes score was ≥4 in 90%. Median follow-up was 37 months (range 2-87). 5-year OS was 56%, with median overall survival (OS) not reached. It was worse in men, ≥65 years, high-risk and those with increased prolymphocytes (CLL/PL). This study shows low incidence and worse OS in Chilean CLL patients, compared to those from European countries, despite similar clinical features. It also demonstrates that CLL is very uncommon in Amerindian population.

Abstract
BACKGROUND Chronic lymphocytic leukaemia (CLL) is the most common leukaemia among adults in western countries. Considering the increasing incidence and prevalence of this condition, it is highly relevant to better characterise these patients in Portugal, where data is still scarce. METHODS To determine incidence, clinical presentation, survival and second malignancies, a population-based historical cohort study was conducted. Cases of interest were identified through the South Region Cancer Registry database and additional data sources. Patients aged ≥18 years, with a confirmed diagnosis of CLL or small lymphocytic lymphoma between January 1st, 2013 and December 31st, 2014 were included. Patients were followed-up until death or cut-off date (December 31st, 2019). RESULTS A total of 496 patients were included and median follow-up time was 5.46 years. Crude incidence rates were 5.03 and 5.22 per 100,000 inhabitants for 2013 and 2014, respectively, and age-adjusted incidence rates were 3.18:100,000 European population for 2013 and 3.35:100,000 European population for 2014. Median age at diagnosis was 71 years and the male/female ratio was 1.40. The majority of patients had leukemic presentation of the disease (86.09%), was diagnosed in Binet stage A (75.58%) and did not present B symptoms (84.01%), anaemia (haemoglobin ≤10g/dL; 90.63%) nor thrombocytopenia (platelet count ≤100 000/μL; 91.73%). Five-year overall survival (OS) rate was 70.53% (95%CI 66.31-74.34) and age, lactate dehydrogenase, Binet stage and a ≥5 Charlson comorbidity index score were independently associated with OS. Standardised-incidence ratios for any second malignancy and cutaneous squamous cell carcinoma were 1.59 (95%CI 1.19-2.08) and 10.15 (95%CI 6.28-15.51), respectively. CONCLUSION Incidence, clinical presentation and survival of CLL Portuguese patients are similar to those reported for other western countries. The increased risk of second malignancies raises concerns and needs adequate clinical watchfulness.

The impact of increasing karyotypic complexity and evolution on survival in CLL patients treated with ibrutinib. Blood 2021; 138:2372-2382. [PMID: 34314481 DOI: 10.1182/blood.2020010536] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2021] [Accepted: 07/07/2021] [Indexed: 11/20/2022] Open
Abstract
Complex karyotype defined as ≥3 cytogenetic abnormalities is prognostic of survival in patients treated with ibrutinib or venetoclax in relapsed/refractory (RR) chronic lymphocytic leukemia (CLL). Recent studies re-evaluating this dichotomous variable have shown that higher numbers of cytogenetic abnormalities (i.e. ≥5) have a worse overall survival in patients treated with chemoimmunotherapy. We sought to determine if increasing karyotypic complexity, treated as a continuous variable, was prognostic of survival for patients treated with ibrutinib for CLL. We conducted a retrospective analysis of all patients with CLL treated with single-agent ibrutinib or in combination with an anti-CD20 antibody at our institution. We included 456 patients with both treatment-naïve (TN) and RR disease. Median number of prior therapies was 2 (range 0-13), 30% of patients had del(17p), and 75% were IGHV unmutated. 50% had ≥3 cytogenetic abnormalities including 30% with ≥5. In a multivariable analysis, increasing karyotypic complexity was an independent predictor of shorter progression-free survival (HR 1.07 (95% CI 1.04-1.10), p<0.0001) and overall survival (HR 1.09 (95% CI 1.05-1.12), p<0.0001). Furthermore, we found that presence of clonal evolution determined by cytogenetic analysis at progression was prognostic of subsequent survival (p=0.02). This solidifies karyotypic complexity as an important prognostic factor for CLL patients treated with ibrutinib. Further research should consider sequential karyotypic analysis as a determination of risk of progression and death in patients with CLL.

Abstract
The paradigm of first-line treatment of chronic lymphocytic leukaemia (CLL) is currently undergoing a radical change. On the basis of several randomised phase III trials showing prolongation of progression-free survival, chemoimmunotherapy is being replaced by treatment based on novel, orally available targeted inhibitors such as Bruton tyrosine kinase inhibitors ibrutinib and acalabrutinib or bcl-2 inhibitor venetoclax. However, the use of these agents may be associated with other disadvantages. First, with the exception of one trial in younger/fit patients, no studies have so far demonstrated benefit regarding the ultimate endpoint of overall survival. Second, oral inhibitors are extremely expensive and thus currently unavailable due to the absence of reimbursement in some countries. Third, treatment with ibrutinib and acalabrutinib necessitates long-term administration until progression; this may be associated with accumulation of late side effects, problems with patient compliance, and selection of resistant clones. Therefore, the identification of a subset of patients who could benefit from chemoimmunotherapy would be ideal. Current data suggest that patients with the mutated variable region of the immunoglobulin heavy chain (IGHV) achieve fairly durable remissions, especially when treated with fludarabine, cyclophosphamide, and rituximab (FCR) regimen. This review discusses current options for treatment-naïve patients with CLL.

Abstract
The development of highly effective targeted therapies has led to a new treatment paradigm in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL/SLL). Despite these advances, many patients will eventually require alternative treatment strategies due to the emergence of tolerability issues or resistance to these novel agents. Duvelisib is a first-in-class, potent oral agent with dual inhibitor activity against the δ and γ isoforms of phosphoinositide 3-kinase (PI3Kδ and PI3Kγ), which are specific to the hematopoietic system. Dysregulation of the PI3K/PTEN/AKT/mTOR pathway has been implicated in cancer cell growth, survival and metabolism and has been the subject of cancer drug development in recent years. Duvelisib demonstrated activity in CLL/SLL in early trials, leading to further evaluation in the Phase 3 DUO trial that compared duvelisib against ofatumumab in patients with relapsed/refractory CLL/SLL. This trial led to the Food and Drug Administration (FDA) approval for the treatment of adult patients with CLL/SLL after at least two prior lines of therapy. The major reason for therapy discontinuation is the development of serious adverse events, which include severe infections and diarrhea/colitis, precluding its widespread use. Ongoing clinical trials are evaluating duvelisib in combination strategies and with alternate dosing schedules in patients with CLL/SLL. With close monitoring, duvelisib can be a promising drug for the treatment of patients with relapsed or refractory CLL/SLL. This review summarizes the relevant clinical data from recent clinical advances in CLL and aims to interpret the duvelisib trials while exploring strategies to improve its use and adverse event management in the era of novel targeted agents.

Abstract
Ibrutinib is indicated for the treatment of chronic lymphocytic leukemia (CLL). Absolute lymphocyte count (ALC) is a clinical criterion used for the monitoring of CLL. Ibrutinib has several effects on lymphocytes, and has highly variable pharmacokinetics (PK). The objective of this work was to build a PK-pharmacodynamic (PD) model describing ALC dynamics under ibrutinib treatment in patients with CLL. ALC observations before and after ibrutinib treatment initiation in patients with CLL were included in the analysis. A population PK-PD model was developed based on physio-pharmacological knowledge. Individual PK concentrations at each hospital visit were included in the model. The association between PD parameters and lymphocytosis, and between PD parameters and response to treatment were assessed. A total of 94 patients, 658 ALC and 1,501 PK observations were included in model development. The final PK-PD model accurately described ALC dynamics for different patient profiles. It consisted in two compartments (tissues and blood circulation) with ibrutinib plasmatic concentration inducing two drug effects: stimulation of lymphocyte redistribution and death. Patients with hyperlymphocytosis had significantly higher tissues to circulation baseline lymphocyte count ratio, and lower death effect. Patients who progressed under ibrutinib had significantly lower baseline lymphocyte counts in tissues (2-fold lower) and blood (3-fold lower). The first PK-PD model for ALC in patients with CLL under ibrutinib treatment was developed. This model suggests that estimated lymphocyte counts in tissues and blood could be used as an early predictor of response in patients with CLL.

Abstract
PURPOSE Determining chronic lymphocytic leukemia (CLL) prognosis using the International Prognostic Index markers such as TP53 and immunoglobulin heavy-chain variable region gene mutation in a resource-limited setting is difficult to achieve because of cost and equipment unavailability. The aim of this study is to determine prognostic factors easily available to hematologists in low- or medium-income countries. MATERIALS AND METHODS This was a retrospective study conducted at the University of Port Harcourt Teaching Hospital, Nigeria. Data were retrieved from CLL patient records from January 2004 to December 2019 (15 years). Data collected were analyzed using SPSS software version 25. RESULTS A total of 46 records were reviewed, with a median age of 55 years and a male:female ratio of 1:1.2. All patients were symptomatic at presentation, with splenomegaly (91.3%), anemia (82.6%), and lymphadenopathy (76.1%) predominating. About 89.1% of the patients presented at Binet stage C and/or high-risk Rai (Rai stages III and IV) with 10.9% presenting at Binet stage B and/or intermediate-risk Rai (Rai stage II). Only 13% of the patients had immunophenotyping done with 6.5% being done for the Matutes CLL score. The 5-year overall survival (OS) was 15.7% with a median survival of 26 months. WBC count and absolute lymphocyte count (ALC) > 100 × 109/L were significant poor prognostic markers (P = .013 and .021, respectively). Thirty-five (76.1%) received chemotherapy, and they had a better median survival than those who did not (26 v 17.5 months). The most common regimen used was cyclophosphamide, vincristine, and prednisolone for 15 (42.9%) patients. CONCLUSION WBC count and ALC > 100 × 109/L were poor prognostic markers. Patients who received chemotherapy had a better OS.

Abstract
Background:
The therapeutic outcomes and the prognosis of patients with various hematologic
malignancies are not always ideal with the current standard of care.
Objective:
The aim of this study is to analyze the results of the use of monoclonal antibodies, bispecific
antibodies and antibody-drug conjugates for the therapy of malignant hemopathies.
Methods:
A mini-review was achieved using the articles published in Web of Science and PubMed
between January 2017 and January 2020 and the new patents were made in this field.
Results:
Naked monoclonal antibodies have improved the therapeutic results obtained with standard
of care, but they also have side effects and the use of some of them can lead to the loss of the
target antigen through trogocytosis, which explains the resistance that occurs during therapy. The
results obtained with naked monoclonal antibodies have been improved by a better monoclonal
antibody preparation, the use of bispecific antibodies (against two antigens on the target cell surface
or by binding both surface antigen on target cells and T-cell receptor complex, followed by cytotoxic
T-lymphocytes activation and subsequent cytolysis of the target cell), the use of monoclonal
or bispecific constructs in frontline regimens, combining immunotherapy with chemotherapy, including
through the use of antibody-drug conjugates (which provides a targeted release of a chemotherapeutic
agent).
Conclusion:
Immunotherapy and immuno-chemotherapy have improved the outcome of the patients
with malignant hemopathies through a targeted, personalized therapy, with reduced systemic
toxicity, which in some cases can even induce deep complete remissions, including minimal residual
disease negativity.
