Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.SEQUOIA (ClinicalTrials.gov identifier: NCT03336333) is a phase III, randomized, open-label trial that compared the oral Bruton tyrosine kinase inhibitor zanubrutinib to bendamustine plus rituximab (BR) in treatment-naïve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). The initial prespecified analysis (median follow-up, 26.2 months) and subsequent analysis (43.7 months) found superior progression-free survival (PFS; the primary end point) in patients who received zanubrutinib compared with BR. At a median follow-up of 61.2 months, median PFS was not reached in zanubrutinib-treated patients; median PFS was 44.1 months in BR-treated patients (hazard ratio [HR], 0.29; one-sided P = .0001). Prolonged PFS was seen with zanubrutinib versus BR in patients with mutated immunoglobulin heavy-chain variable region (IGHV) genes (HR, 0.40; one-sided P = .0003) and unmutated IGHV genes (HR, 0.21 [95% CI, 0.14 to 0.33]; one-sided P < .0001). Median overall survival (OS) was not reached in either treatment arm; estimated 60-month OS rates were 85.8% and 85.0% in zanubrutinib- and BR-treated patients, respectively. No new safety signals were detected. Adverse events were as expected with zanubrutinib; rate of atrial fibrillation was 7.1%. At a median follow-up of 61.2 months, the results supported the initial SEQUOIA findings and suggested that zanubrutinib was a favorable treatment option for untreated patients with CLL/SLL.

OBJECTIVES: This study aims to identify factors possibly contributing to complications in children with acute leukaemia. Despite diverse etiological causes, similar processes trigger the process of cell malignancy. Genomic instability has received considerable attention in this context. METHOD: We conducted chromosomal analysis of bone marrow cells and measured the micronuclei (Mn) level in buccal cells over time. Statistical reliability assessment was performed using Analysis of variance (ANOVA), and the data were analyzed and visualized using the SPSS 12 statistical analysis software package. RESULTS: On the 15th day of treatment, our findings confirmed a statistically significant correlation (χ2=3.88, P=0.04) between the number of blasts in the bone marrow and unfavourable outcome in patients with a near-tetraploid chromosome clone. Additionally, on the 33rd day of treatment, we observed a correlation between an elevated number of Mn and relapses. DISCUSSION: While it is commonly believed that a hyperdiploid clone with >50 chromosomes in childhood acute lymphoblastic leukaemia confers favorable outcome, our study revealed partially heterogeneous results and poor prognosis in patients with a near-tetraploid clone. We have also identified a correlation between the Mn level on the 33rd day of treatment and the development of complications. It is possible that the increased Mn values and the occurrence of relapses were influenced by the individual patient's sensitivity to the genotoxic effect of the medication.

Can peripheral blood be used to detect residual disease in acute lymphoblastic leukaemia (ALL) when we increase the sensitivity of the method used? Bendig et al. found that a larger amount of material and the use of next-generation sequencing (NGS) detects MRD in peripheral blood in up to half of patients with B-cell precursor ALL (BCP-ALL) where routine examination was negative. However, a negative result does not exclude the presence of residual disease and thus still limits the use of peripheral blood. Commentary on: Bendig et al. Next-generation sequencing and high DNA input identify previously missed measurable residual disease in peripheral blood of B-cell precursor acute lymphoblastic leukaemia. Br J Haematol 2025; 206:353-356.
BACKGROUND: Auer rods (AuRs) are prominent intracellular structures found almost exclusively in myeloid cell malignancies, such as acute myeloid leukemia (AML), chronic and juvenile myelomonocytic leukemia and myelodysplastic syndrome. Extremely rare AuRs have been reported in patients with acute lymphoblastic leukemia (ALL) or among ambiguous lineage leukemia patients with a dominantly lymphoblastic immunophenotype. PROCEDURE: We report diagnostic and follow-up data of an international cohort of 11 children suffering from leukemias with AuRs and with significant presence of T and myeloid markers, majority of whom categorized as early T-cell precursor (ETP, n = 7); or T-ALL (ETP status unknown, n = 2), ALAL (acute leukemia of ambiguous lineage, n = 1), and AML reclassified from ALAL (n = 1). We described other diagnostic details and treatment types and responses. Moreover, we summarize previously published data. RESULTS: Among the four patients who started and remained on ALL-type therapy, all were in the first complete remission, whereas both patients who started and remained on AML-type therapy relapsed and died. Of the patients who followed either a combined ALL/AML protocol (Interfant 06) or who switched from one of the two types of therapy to the other, one patient died, and the remaining four were in first complete remission at the most recent follow-up. We also searched for similar cases in the literature and found only three additional children with nonmyeloid leukemia and AuRs and 10 adults with this type of leukemia. CONCLUSIONS: Briefly, ALL- or combined ALL/AML-type therapy may be effective for treating AuR-positive leukemia patients with a lymphoid immunophenotype.

PURPOSE: To assess motor performance among Czech paediatric off therapy patients of acute lymphoblastic leukaemia (ALL) and to compare their data with normative data. METHODS: Thirty-nine off therapy patients (21 girls, 18 boys; aged 4-21 years) were evaluated using the Complete Form of the Bruininks-Oseretsky Test Second Edition (BOT-2 CF) approximately 1.5 years post-therapy cessation. Gross and fine motor skills were assessed. Normative data from BOT-2 CF served as the basis for comparison. RESULTS: The total motor composite (p = .381, Cohen's d = 0.14) and overall fine (p = .743; Cohen's d = 0.05) and gross (p=.312; Cohen's d = 0.16) motor performance were similar to the normative data. Motor deficits in manual coordination (p = .018; Cohen's d = 0.45), strength and agility (p = .012; Cohen's d = 0.51), manual dexterity (p < .001; Cohen's d = 0.59) and running speed and agility (p < .001; Cohen's d = 0.97) were identified, along with performance better than the established norms on fine motor integration (p = .048; Cohen's d = 0.33) and bilateral coordination (p = .018; Cohen's d = 0.47). CONCLUSION: The findings suggest nuanced motor skill outcomes in ALL off therapy patients, with both deficits and strengths observed. Comprehensive assessments are vital for tailoring rehabilitation strategies to address the varied impacts of ALL and its treatment on motor skills.

The superiority of total body irradiation (TBI)-based vs chemotherapy conditioning for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in children with acute lymphoblastic leukemia (ALL) has been established in the international, prospective phase-3 FORUM study, randomizing 417 patients aged 4-18 years in complete remission (CR), who received allo-HSCT from HLA-matched sibling or unrelated donors. Because of the unavailability of TBI in some regions and to accommodate individual contraindications, this study reports the prespecified comparison of outcomes of patients receiving busulfan (BU)- or treosulfan (TREO)-based regimens from 2013 to 2018. Overall, 180 and 128 patients received BU/thiotepa (THIO)/fludarabine (FLU) or TREO/THIO/FLU, respectively. Data were analyzed as of February 2023, with a median follow-up of 4.2 years (range, 0.3-9.1). 3-year overall survival was 0.71 (BU, 95% confidence interval [0.64-0.77]) and 0.72 (TREO, [0.63-0.79]) and 3-year event-free survival was 0.60 (BU, [0.53-0.67]) and 0.55 (TREO, [0.46-0.63]). The 3-year cumulative incidence of relapse (BU, 0.31 [0.25-0.38]; TREO, 0.36 [0.27-0.44]); and nonrelapse mortality (BU, 0.08 [0.05-0.13]; TREO, 0.09 [0.05-0.15]) were comparable. One case of fatal veno-occlusive disease occurred in each group. No significant differences in acute and chronic graft-versus-host disease (GVHD) or 3-year GVHD-free and relapse-free survival (BU, 0.48 [0.41-0.55]; TREO, 0.45 [0.37-0.54]) were recorded. Outcomes for patients in first and second CR were similar irrespective of the regimen. In conclusion, BU/THIO/FLU or TREO/THIO/FLU regimens can be an alternative to TBI for patients with ALL aged >4 years with contraindications or lack of access to TBI. This trial was registered at www.ClinicalTrials.gov as #NCT01949129.

BACKGROUND: Whether fixed-duration acalabrutinib-venetoclax (with or without obinutuzumab) would result in better progression-free survival than chemoimmunotherapy in patients with untreated chronic lymphocytic leukemia (CLL) is unknown. METHODS: In this phase 3, open-label trial, we included patients 18 years of age or older who had an Eastern Cooperative Oncology Group performance-status score of 0 to 2 (range, 0 to 5, with higher numbers indicating greater disability) and who did not have a 17p deletion or TP53 mutation. Patients were randomly assigned, in a 1:1:1 ratio, to receive acalabrutinib-venetoclax (acalabrutinib, cycles 1 to 14; venetoclax, cycles 3 to 14), acalabrutinib-venetoclax-obinutuzumab (as above, plus obinutuzumab, cycles 2 to 7), or chemoimmunotherapy with the investigator's choice of fludarabine-cyclophosphamide-rituximab or bendamustine-rituximab (cycles 1 to 6). The primary end point was progression-free survival (acalabrutinib-venetoclax vs. chemoimmunotherapy) in the intention-to-treat population, assessed by blinded independent central review. RESULTS: A total of 867 patients underwent randomization: 291 were assigned to receive acalabrutinib-venetoclax, 286 acalabrutinib-venetoclax-obinutuzumab, and 290 chemoimmunotherapy (of whom 143 received fludarabine-cyclophosphamide-rituximab and 147 bendamustine-rituximab). The median age of the patients was 61 years (range, 26 to 86), 64.5% were men, and 58.6% had unmutated IGHV. Estimated 36-month progression-free survival at a median follow-up of 40.8 months was 76.5% with acalabrutinib-venetoclax, 83.1% with acalabrutinib-venetoclax-obinutuzumab, and 66.5% with chemoimmunotherapy (hazard ratio for disease progression or death with acalabrutinib-venetoclax vs. chemoimmunotherapy, 0.65 [95% confidence interval {CI}, 0.49 to 0.87], P = 0.004; for the comparison of acalabrutinib-venetoclax-obinutuzumab with chemoimmunotherapy, P<0.001). Estimated 36-month overall survival was 94.1% with acalabrutinib-venetoclax, 87.7% with acalabrutinib-venetoclax-obinutuzumab, and 85.9% with chemoimmunotherapy. Neutropenia, the most common adverse event of clinical interest of grade 3 or higher, was reported in 32.3%, 46.1%, and 43.2% in the three groups, respectively; death from coronavirus disease 2019 was reported in 10, 25, and 21 patients in the three groups. CONCLUSIONS: Acalabrutinib-venetoclax with or without obinutuzumab significantly prolonged progression-free survival as compared with chemoimmunotherapy in fit patients with previously untreated CLL.

The ALPINE trial established the superiority of zanubrutinib over ibrutinib in patients with relapsed/refractory chronic lymphocytic leukemia and small lymphocytic lymphoma; here, we present data from the final comparative analysis with extended follow-up. Overall, 652 patients received zanubrutinib (n = 327) or ibrutinib (n = 325). At an overall median follow-up of 42.5 months, progression-free survival benefit with zanubrutinib vs ibrutinib was sustained (hazard ratio [HR], 0.68; 95% confidence interval [CI], 0.54-0.84), including in patients with del(17p)/TP53 mutation (HR, 0.51; 95% CI, 0.33-0.78) and across multiple sensitivity analyses. Overall response rate remained higher with zanubrutinib compared with ibrutinib (85.6% vs 75.4%); responses deepened over time with complete response/complete response with incomplete bone marrow recovery rates of 11.6% (zanubrutinib) and 7.7% (ibrutinib). Although median overall survival has not been reached in either treatment group, fewer zanubrutinib patients have died than ibrutinib patients (HR, 0.77 [95% CI, 0.55-1.06]). With median exposure time of 41.2 and 37.8 months in zanubrutinib and ibrutinib arms, respectively, the most common nonhematologic adverse events included COVID-19-related infection (46.0% vs 33.3%), diarrhea (18.8% vs 25.6%), upper respiratory tract infection (29.3% vs 19.8%), and hypertension (27.2% vs 25.3%). Cardiac events were lower with zanubrutinib (25.9% vs 35.5%) despite similar rates of hypertension. Incidence of atrial fibrillation/flutter was lower with zanubrutinib vs ibrutinib (7.1% vs 17.0%); no cardiac deaths were reported with zanubrutinib vs 6 cardiac deaths with ibrutinib. This analysis, at 42.5 months median follow-up, demonstrates that zanubrutinib remains more efficacious than ibrutinib with an improved overall safety/tolerability profile. This trial was registered at www.ClinicalTrials.gov as #NCT03734016.

Chronická lymfocytární leukemie (chronic lymphocytic leukemia, CLL) patří mezi indolentní lymfoproliferativní onemocnění vycházející z B lymfocytů. V západních zemích je CLL nejčastější leukemií v dospělé populaci. Zavedení inhibitorů Brutonovy kinázy (Bruton tyrosine kinase inhibitors, BTKi) znamenalo průlom v léčbě CLL a významně prodloužilo přežití pacientů s touto diagnózou. Ve srovnání a chemoimunoterapií prokazují lepší účinnost i toleranci léčby, zejména u rizikových pacientů s mutací genu TP53 a/nebo delecí 17p. Léčba BTKi dala naději na dlouhodobou kontrolu nemoci pacientům s časným relapsem CLL po chemoimunoterapii a pacientům s chemorefrakterní CLL. Jejich perorální podávání je pro ambulantní léčbu pacientů velkou výhodou. Na druhou stranu, je třeba myslet na specifické nežádoucí účinky této lékové skupiny. Zejména poruchy agregace trombocytů a kardiovaskulární nežádoucí účinky bývají limitací v léčbě a v závažných případech mohou být i život ohrožující. V tomto článku se věnujeme správné indikaci léčby BTKi u CLL, shrnujeme výsledky z klinických studií a doporučení pro management jejich případné toxicity.
Chronic lymphocytic leukemia (CLL) is an indolent B-ceLL lymphoproliferative disorder and the most common leukemia in the adult population in Western countries. Bruton tyrosine kinase inhibitors (BTKi) represent a major breakthrough in the treatment of CLL, significantly prolonging the survival of patients with this disease. Compared to chemoimmunotherapy, BTKi have demonstrated better efficacy and tolerability, particularly in high-risk patients with TP53 mutations or 17p deletions. Bruton tyrosine kinase inhibitors treatment has offered a long-term disease control even in patients with relapsed or refractory CLL after chemoimmunotherapy. The oral administration of these drugs is an additional advantage, allowing for outpatient treatment. However, it is important to be aware of the specific toxicity associated with this drug class. Platelet dysfunction and cardiovascular complications are among the most common issues, and in severe cases, these adverse events can be life-threatening. In this article, we discuss the indications for treatment with Bruton kinase inhibitors, summarize data from clinical trials, and review aspects of treatment-related toxicity.

PURPOSE: The AIEOP-BFM ALL 2009 protocol included, at the end of the induction phase, a randomized study of patients with high-risk (HR) ALL to investigate if an intensive exposure to pegylated L-asparaginase (PEG-ASNASE, 2,500 IU/sqm once a week × 4) on top of BFM consolidation phase IB allowed us to decrease minimal residual disease (MRD) and improve outcome. PATIENTS AND METHODS: A total of 1,097 patients presented, from June 2010 to February 2017, with one or more of the following HR criteria: KMT2A::AFF1 rearrangement, hypodiploidy, prednisone poor response, poor bone marrow response at day 15 (Flow MRD ≥10%), or no complete remission (CR) at the end of induction. Of them, 809 (85.1%) were randomly assigned to receive (404) or not receive (405) four weekly doses of PEG-ASNASE. RESULTS: By intention to treat (ITT) analysis, there was no significant difference in the proportion of patients with polimerase chain reaction MRD ≥5 × 10-4 at the end of phase IB in the experimental versus control arm (13.9% v 17.0%, P = .25). The 5-year event-free survival (median follow-up 6.3 years) by ITT in the experimental and control arms was 70.4% (2.3) versus 75.0% (2.2; P = .18), and the 5-year overall survival was 81.5% (2.0) versus 84.0% (1.9; P = .25), respectively. The corresponding 5-year cumulative incidence of death in CR was 9.5% (1.5) versus 5.7% (1.2; P = .08), and that of relapse was 17.7% (1.9) versus 17.2% (1.9), respectively (P = .94). Adverse reactions in phase IB occurred in 22.2% and 8.9% of patients in the experimental and control arm, respectively (P < .001). CONCLUSION: Additional PEG-ASNASE in phase IB did not translate into a benefit for decreasing relapse incidence but was associated with higher toxicity. Further improvements with conventional chemotherapy might be difficult in the context of intensive treatment protocols.
