Quizartinib for patients with newly diagnosed FLT3-ITD-positive AML who received maintenance therapy in QuANTUM-First.

QuANTUM-First demonstrated improved overall survival (OS) in patients with newly diagnosed acute myeloid leukemia with FMS-like receptor tyrosine kinase 3-internal tandem duplication (FLT3-ITD) treated with quizartinib + standard chemotherapy. Herein, we evaluated the impact of postconsolidation/posttransplant single-agent maintenance therapy on clinical outcomes in patients receiving maintenance, focusing on measurable residual disease (MRD) status at maintenance onset. OS, event-free survival, and relapse-free survival were prespecified exploratory analyses. Cumulative incidence of relapse, analyses by allogeneic hematopoietic cell transplant (allo-HCT), and analyses by MRD status were post hoc and not powered for statistical significance. Samples for FLT3-ITD MRD analysis were collected from patients with composite complete remission ≤30 days before receiving maintenance and assessed using an ultrasensitive amplicon-based assay. More patients who had received an allo-HCT and quizartinib treatment received maintenance (71%) vs placebo (55%); OS benefit was not demonstrated among these patients. In patients who did not undergo allo-HCT, quizartinib maintenance was associated with a significant OS benefit (hazard ratio [HR], 0.401; 95% confidence interval [CI], 0.192-0.838), including a benefit in patients who were MRD negative at the start of maintenance (OS HR, 0.194; 95% CI, 0.056-0.676). Patients who were MRD negative at the completion of consolidation achieved 89.1% (95% CI, 70.0-96.4) survival at 3 years with quizartinib maintenance in the absence of allo-HCT. These data suggest that for patients who achieve FLT3-ITD MRD negativity after induction and consolidation with quizartinib, maintenance with quizartinib provides a significant survival benefit and, in some patients, may eliminate the need for allo-HCT. This trial was registered at www.clinicaltrials.gov as NCT02668653.

Day + 30 detection of minimal residual FLT3-ITD by high-sensitivity PCR-NGS predicts relapse risk and guides post-transplant maintenance in AML.

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) has improved outcomes in patients with acute myeloid leukemia (AML) harboring FLT3-internal tandem duplication (FLT3-ITD) mutations. However, relapse still occurs in 15-35% of these patients after transplantation. Therefore, early and highly sensitive detection methods are required to identify patients at risk of relapse and enable timely post-transplant intervention. METHODS: In this NICHE cohort study, a total of 136 patients were included, then we evaluated whether high-sensitivity polymerase chain reaction (PCR)-next-generation sequencing (NGS) for FLT3-ITD (limit of detection: 5 × 10-6) on day + 30 post-HSCT could identify patients at a high risk of relapse and inform decisions regarding maintenance therapy. RESULTS: Among the 136 patients, 37 patients (27.2%) had detectable FLT3-ITD clones on day + 30. These patients exhibited a significantly higher cumulative incidence of post-HSCT multiparameter flow cytometry (MFC)-measurable residual disease (MRD) relapse (40.3% vs. 18.8%, p = 0.001). Notably, FLT3-ITD-positive patients who received FLT3 inhibitor maintenance therapy had no relapses, while 6 out of the 13 patients who did not receive maintenance therapy relapsed. Conversely, FLT3-ITD-negative patients without high-risk factors (2022 European LeukemiaNet adverse-risk group, relapsed/refractory AML, MFC-MRD positivity pre-HSCT) showed limited benefit from maintenance therapy (MFC-MRD-free survival: hazard ratio (HR) = 0.25 (0.03-2.11), p = 0.204; OS: HR = 0.20 (0.02-1.70), p = 0.142). CONCLUSIONS: This is the first study to demonstrate that detection of minimal FLT3-ITD clones at the fixed time point of day + 30 post-HSCT can reliably stratify relapse risk in AML patients and provide a rationale for individualized post-transplant maintenance therapy.

Rationale and Study Design of the GUIDANCE trial: A Multicenter Phase II Trial of Maintenance Durvalumab and Olaparib After Standard Fist Line Treatment (Carboplatin/Cisplatin, Etoposide, and Durvalumab) in HRD Positive Extensive Disease (ED) Small-cell Lung Cancer (SCLC) (AIO-TRK-0124/ass).

BACKGROUND: Small-cell lung cancer (SCLC) is an aggressive malignancy with poor prognosis and limited therapeutic progress over recent decades. Although PD-L1 inhibitors have modestly improved survival, responses are not durable. There are no predictive biomarkers that would allow for a personalized treatment strategy. Targeting DNA damage repair deficiencies represents a promising treatment strategy in various solid tumors. Poly (ADP-ribose) polymerase (PARP) inhibitors such as olaparib have demonstrated efficacy in homologous recombination deficiency (HRD)-positive tumors, and preclinical data suggest synergistic activity with immune checkpoint blockade. METHODS: GUIDANCE is a biomarker-driven, multicenter, single-arm, open-label phase II trial evaluating maintenance therapy with durvalumab and olaparib in patients with advanced or metastatic SCLC without progression after first-line therapy with platinum, etoposide and durvalumab. Patients are prospectively selected for HRD based on homologous recombination repair gene alterations and/or a genomic instability score. Following central prescreening, 29 patients will be enrolled. Patients receive durvalumab (1500 mg every 4 weeks) and olaparib (300 mg twice daily) until progression or unacceptable toxicity. The primary endpoint is progression-free survival (PFS) by RECIST 1.1. Secondary endpoints are overall survival, safety and tolerability. Exploratory analyses include circulating tumor DNA (ctDNA) monitoring of individual TP53 mutations, assessment of SLFN11 expression, and characterization of immune cell composition via multiplex immunohistochemistry. DISCUSSION: This trial investigates a chemotherapy-free, genomically stratified maintenance strategy targeting both DNA damage repair deficiency and immune evasion in SCLC. By integrating HRD-based patient selection with concurrent PARP and immune checkpoint inhibition, GUIDANCE aims to establish a more individualized therapeutic approach and to generate a signal for further evaluation in biomarker-defined patient populations. Trial registration number EuraCT 2024-512373-27-00.

Osimertinib With or Without Chemotherapy in Advanced Non-Small Cell Lung Cancer With EGFR and Concurrent TP53 Mutations: A Randomized Clinical Trial.

IMPORTANCE: Combination therapy has emerged as a promising therapeutic approach for patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC). However, its clinical benefit-risk profile remains a focus of ongoing debate. Identifying patients most likely to derive benefit from such regimens remains an unmet clinical need. OBJECTIVE: To prospectively compare the efficacy and safety of first-line osimertinib plus chemotherapy with osimertinib monotherapy for patients with EGFR-mutated advanced NSCLC harboring concurrent TP53 mutations. DESIGN, SETTING, AND PARTICIPANTS: A multicenter, randomized, open-label, phase 3 study conducted at 17 sites in China. Between March 25, 2021, and July 11, 2024, a total of 294 eligible patients with treatment-naive, stage IV or recurrent nonsquamous NSCLC harboring concurrent TP53 and EGFR-sensitizing mutations were enrolled. INTERVENTIONS: Patients were randomized (1:1) to receive osimertinib plus chemotherapy (pemetrexed and carboplatin every 3 weeks for 4 cycles, followed by maintenance therapy of osimertinib plus pemetrexed; n&#x2009;=&#x2009;146) or osimertinib monotherapy (n&#x2009;=&#x2009;148). MAIN OUTCOMES AND MEASURES: The primary end point was investigator-assessed progression-free survival. Secondary end points included overall survival, response, safety, and quality of life. RESULTS: Among 294 enrolled patients, the median age was 57 years (range, 26-79 years), and 159 (54.1%) were female. The data cutoff date was November 11, 2025. At a median follow-up of 25.1 months for the osimertinib-chemotherapy group and 26.1 months for the osimertinib monotherapy group, median progression-free survival was significantly longer with osimertinib plus chemotherapy than with osimertinib monotherapy (34.0 vs 15.6 months; difference, 18.4 months [95% CI, 9.9-22.3]; hazard ratio, 0.44 [95% CI, 0.32-0.60]; P&#x2009;<&#x2009;.001). This benefit was consistent across prespecified subgroups, including those with brain metastases and L858R mutations. The overall survival data remained immature (30.6% maturity); however, a trend toward overall survival benefit with combination therapy was observed. The incidence of grade 3 or higher treatment-related adverse events was higher in the combination group, with no new safety signal identified. CONCLUSIONS AND RELEVANCE: In this randomized clinical trial, osimertinib plus chemotherapy significantly increased progression-free survival among patients with EGFR-mutated advanced NSCLC harboring concurrent TP53 mutations. These findings provided a clinical rationale for individualized combination strategies in the management of patients with EGFR-mutated NSCLC.

Age-related distribution of homologous recombination deficiency in advanced ovarian carcinoma: a large real-world French cohort.

OBJECTIVE: Tumor genetic testing for BRCA and homologous recombination repair is essential for guiding maintenance therapy in high-grade non-mucinous ovarian carcinomas. While clinical trials (PAOLA-1, PRIMA, ATHENA-MONO, PRIME) have reported homologous recombination deficiency rates of 44% to 67% in cohorts with a median age of 61, real-world data suggest age-related variations. We aimed to evaluate homologous recombination deficiency prevalence in a large French population and hypothesized a distribution pattern similar to the recent German findings published in 2022, in which older age correlated with lower homologous recombination deficiency rates. METHODS: We retrospectively analyzed advanced ovarian carcinoma cases referred to the Dijon Cancer Center from 191 care centers between 2022 and 2024 for Myriad MyChoice homologous recombination deficiency testing. Data collected included age, histologic type, homologous recombination deficiency status, homologous recombination proficiency status, and genomic instability scores. We compared the distribution of homologous recombination deficiency and HRP tumors in women <60 and &#x2265;60 years using the &#x3c7;2 test. RESULTS: In 1322 advanced ovarian carcinoma cases with a median age of 70.1 years, the overall rates were 35.3% homologous recombination deficiency and 64.7% homologous recombination proficiency. A sub-analysis of 1226 high-grade cases (median age 70.4; including high-grade serous carcinoma, clear-cell carcinoma, undifferentiated carcinomas, and carcinosarcoma) showed 36.5% homologous recombination deficiency and 63.5% homologous recombination proficiency. Notably, patients aged &#x2265;60 years had a significantly higher likelihood of presenting with a homologous recombination proficiency tumor compared with those aged <60 years (65.8% vs 53.2%, p < .001). Among 42 clear-cell carcinoma cases, 97.6% exhibited homologous recombination proficiency status. CONCLUSIONS: In this large real-world cohort of advanced ovarian carcinoma, we observed a notably higher prevalence of homologous recombination proficiency tumors compared to the 4 clinical trials reported in the literature, with homologous recombination proficiency incidence increasing significantly with age. Given that older patients predominantly present with homologous recombination proficiency tumors, which are associated with poorer survival, treatment strategies should be adjusted to better address the specific needs of this demographic.

Daily low-dose carboplatin or weekly carboplatin plus nab-paclitaxel for concurrent chemoradiotherapy in older patients with locally advanced non-small cell lung cancer (JCOG1914): A randomized phase 3 trial.

BACKGROUND: Daily low-dose carboplatin with concurrent thoracic radiotherapy is the standard treatment for older patients with unresectable locally advanced non-small cell lung cancer (LA-NSCLC) in Japan. METHODS: This open-label phase 3 trial was conducted at 38 institutions in Japan. Patients aged&#xa0;&#x2265;&#xa0;75&#xa0;years with LA-NSCLC were randomly assigned (1:1) to receive daily carboplatin (30&#xa0;mg/m2) or weekly carboplatin (area under the curve, 2&#xa0;mg&#xb7;min/mL) plus nab-paclitaxel (30&#xa0;mg/m2) with thoracic radiotherapy. Durvalumab maintenance therapy was recommended after treatment completion. The primary endpoint was overall survival, which was used to assess the non-inferiority of weekly carboplatin plus nab-paclitaxel compared to daily low-dose carboplatin. RESULTS: From December 2020 to March 2024, 124 patients were enrolled (carboplatin arm, 61 and carboplatin plus nab-paclitaxel arm, 63). In the planned interim analysis, the Bayesian predictive probability indicating the non-inferiority of carboplatin plus nab-paclitaxel compared with carboplatin in the final analysis was 8.0%, leading to early study termination for futility. The median overall survival was not estimable in the carboplatin arm; the estimated value in the carboplatin plus nab-paclitaxel arm was 26.1&#xa0;months (hazard ratio, 1.56; 95% confidence interval, 0.79-3.11; p&#xa0;=&#xa0;0.200). Two treatment-related and seven non-cancer-related deaths occurred in the carboplatin plus nab-paclitaxel arm. Patients in the carboplatin arm had better quality of life than those in the carboplatin plus nab-paclitaxel arm at 6&#xa0;weeks (odds ratio, 0.39; 95% confidence interval, 0.18-0.81; p&#xa0;=&#xa0;0.012). CONCLUSIONS: Daily low-dose carboplatin with concurrent thoracic radiotherapy remains the standard treatment for older patients with unresectable LA-NSCLC in Japan.

Journey Mapping of the Patient Experience from Diagnosis to End of Life in Lung Cancer: A Qualitative Meta-Synthesis.

OBJECTIVES: This study aimed to systematically synthesize the lived experiences and journey narratives of lung cancer patients across disease stages, and identify key tasks and pain points during the disease course through patient journey mapping, providing evidence for comprehensive disease management throughout the patient journey. METHODS: Ten databases, including PubMed, Embase, Web of Science, Scopus, PsycINFO, CINAHL, Cochrane Library, CNKI, Wanfang, and SinoMed, were systematically searched, with a search period from database inception to August 15, 2025. The JBI Critical Appraisal Tool for qualitative studies was used to evaluate the quality of studies, and the results were integrated using a meta-aggregative approach. RESULTS: Thirteen studies were included. Based on the patient journey mapping, the lung cancer patient journey comprises four potential stages: evaluation and diagnosis, initial treatment, maintenance therapy, and end-of-life. A total of 30 themes emerged within three dimensions: tasks, emotions, and pain points. Each dimension of each stage consists of 2-3 themes. CONCLUSION: The journey of lung cancer patients is protracted and complex, characterized by stage-specific needs and challenges. Future management strategies should be tailored to these distinct phases, providing precision supportive care to optimize treatment outcomes and enhance patients' quality of life. IMPLICATIONS FOR NURSING PRACTICE: This Patient Journey Map integrates routine clinical pathways with patients' lived experiences across each stage, revealing stage-specific challenges and providing targets for tailored nursing interventions. The framework promotes multidisciplinary, digitally enabled supportive care and indicates the importance of including patients' social circles to enhance patient-centered outcomes.

Comprehensive clinical and genetic characterization of hyperprogressive biliary tract cancer during PD-1 blockade monotherapy: case report and literature review.

BACKGROUND: Some genetically characterized patients show the rapid disease progression during immune checkpoint inhibitors (ICIs) monotherapy, a phenomenon known as hyperprogressive disease (HPD). CASE PRESENTATION: Herein we report a relevant case of biliary tract cancer (BTC) that initially responded to gemcitabine plus oxaliplatin (GEMOX) and PD-1 blockade but subsequently developed HPD in the process of PD-1 blockade maintenance therapy, leading to death within two weeks. Genomic analysis revealed mutations in CDKN2A, PIK3CA, KRAS and EPHA2 in both baseline and hyperprogressive plasma and tumor samples. Notably, higher KRAS mutation abundance was observed in plasma and ascites after disease progression. CONCLUSIONS: These findings suggest a potential association between these negative genes especially KRAS mutation and HPD. Therefore, administration of PD-1 blockade monotherapy in this subgroup of patients harboring KRAS mutation should be performed with caution. Further studies are warranted to confirm these results and explore the correlation between genomic mutations and HPD.

Clopidogrel Versus Dual-Antiplatelet Therapy for Long-Term Maintenance After Coronary Stenting in Ischemic and Bleeding Birisk Patients With Acute Coronary Syndromes and Diabetes: A Prespecified Subgroup Analysis of the OPT-BIRISK Trial.

BACKGROUND: Among patients with acute coronary syndromes at both high bleeding and ischemic risk (birisk), extended clopidogrel monotherapy after 9 to 12&#x2009;months of dual-antiplatelet therapy reduces bleeding without increasing ischemia. Whether this benefit extends to birisk patients with diabetes is unknown. METHODS: This prespecified subgroup analysis of the OPT-BIRISK (Optimal Antiplatelet Therapy for High Bleeding and Ischemic Risk Patients) trial included birisk patients with acute coronary syndrome who had completed 9 to 12&#x2009;months of dual-antiplatelet therapy after percutaneous coronary intervention. Patients were then randomized 1:1 to 9&#x2009;months of clopidogrel&#x2009;plus&#x2009;placebo versus clopidogrel&#x2009;plus&#x2009;aspirin. Outcomes were compared by diabetes status. The primary end point was Bleeding Academic Research Consortium type 2, 3, or 5 bleeding at 9 months after randomization. The key secondary end point was major adverse cardiac and cerebral events, defined as a composite outcome of all-cause death, myocardial infarction, stroke, or clinically driven revascularization. RESULTS: Of 7758 patients, 4072 (52.5%) had diabetes. Clopidogrel monotherapy decreased Bleeding Academic Research Consortium type 2, 3, or 5 bleeding (2.1% versus 3.2%; hazard ratio [HR], 0.66 [95% CI, 0.45-0.97]) with no increase in major adverse cardiac and cerebral events (2.9% versus 3.6%; HR, 0.79 [95% CI, 0.56-1.12]) compared with clopidogrel plus aspirin in patients with diabetes. Outcomes were consistent in patients without diabetes, with no significant interactions by diabetes status. CONCLUSIONS: In birisk patients with acute coronary syndrome who were stable on dual-antiplatelet therapy with clopidogrel plus aspirin for 9 to 12 months after percutaneous coronary intervention, clopidogrel monotherapy for an additional 9 months reduced clinically relevant bleeding without increasing ischemic events compared with continued dual-antiplatelet therapy, irrespective of diabetes status.

Systemic treatment of advanced pancreatic cancer: A Comprehensive Review.

IMPORTANCE: Pancreatic adenocarcinoma (PDAC) is an uncommon but potentially catastrophic diagnosis with historically poor prognosis. It is the tenth most prevalent cancer in the US & UK. Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies worldwide, with a five-year survival rate of approximately 10%. Despite increasing understanding of its molecular biology, systemic treatment options for advanced disease remain limited, and survival outcomes have improved only modestly over the past decade. OBSERVATIONS: This narrative review traces the evolution of systemic therapy for advanced PDAC from gemcitabine monotherapy through the landmark FOLFIRINOX (PRODIGE trial) and gemcitabine/nab-paclitaxel (MPACT trial) combination regimens, which remain the standard of care. Second-line options including liposomal irinotecan plus 5-FU/LV (NAPOLI-1) and maintenance olaparib for germline BRCA1/2-mutated disease (POLO) are also reviewed. Emerging data on sequential treatment strategies (SEQUENCE trial), biomarker-driven treatment selection (PRIMUS-001, PASS-01), and precision medicine approaches targeting actionable molecular subgroups, including dMMR/MSI-H, NTRK fusions, and homologous recombination deficiency are discussed. Real-world evidence comparing FOLFIRINOX and gemcitabine/nab-paclitaxel is critically appraised, including the challenges of patient selection, tolerance, and applicability outside clinical trial settings. CONCLUSION AND RELEVANCE: Despite incremental progress, the treatment landscape of advanced PDAC remains challenging. Molecular stratification and biomarker-driven precision oncology represent the most promising path forward. This review serves as a clinical reference for physicians managing advanced pancreatic cancer, highlighting current evidence, evidence limitations, and future research priorities including prospective biomarker-driven trials and improved access to genomic testing.

Incidence of acne in patients with inflammatory bowel disease treated with Janus kinase inhibitors: a systematic review and meta-analysis.

BACKGROUND: Janus kinase (JAK) inhibitors are effective oral therapies for inflammatory bowel disease (IBD). While acne is a known adverse event in dermatological cohorts, its incidence and risk factors in the IBD population are not well-defined. We aimed to determine the pooled incidence of acne in IBD patients treated with JAK inhibitors and to explore this risk across key clinical subgroups. METHODS: We conducted a systematic review and meta-analysis following PRISMA guidelines. MEDLINE, EMBASE, and CENTRAL were searched from inception to September 2025 for randomized controlled trials (RCTs) and observational studies reporting acne incidence in IBD patients on JAK inhibitors. Data were pooled using a random-effects generalized linear mixed-effects model. Pre-specified subgroup analyses were performed. RESULTS: A total of 50 studies (5 RCTs, 45 observational) involving 9902 IBD patients were included. The overall pooled incidence of acne was 8.6% (95% CI: 6.4%-11.6%). Acne rates were significantly higher (P < .0001) with the upadacitinib (12.2%), compared to tofacitinib (2.6%) and filgotinib (2.3%). A numerically higher incidence was observed during induction (8.6%) versus maintenance (4.2%) therapy, though this difference was not statistically significant (P = .07). The incidence was significantly higher in the pediatric population (12.2%) compared to adults (7.4%) (P = .03). In RCTs, JAK inhibitors were associated with significantly increased odds of acne compared to placebo (OR 2.43, 95% CI: 1.33-4.43, P = .019). No statistically significant difference was observed by IBD subtype. CONCLUSION: Acne is a common adverse event in IBD patients treated with JAK inhibitors. The reported incidence of acne was significantly higher with upadacitinib, in the pediatric population, and numerically higher during the induction phase of treatment.

Impact of Race on Profiles of Platelet Reactivity and Clinical Outcomes in Clopidogrel-Treated Participants.

Black individuals undergoing percutaneous coronary intervention (PCI) experience higher rates of major adverse cardiovascular events (MACE) than non-Black individuals. This study assessed the racial differences in platelet reactivity and clinical outcomes among clopidogrel-treated participants. Two cohorts were analyzed. The pharmacodynamic (PD) cohort involved patients with atherosclerotic cardiovascular disease on maintenance clopidogrel therapy undergoing platelet function testing. The primary outcome was high platelet reactivity (HPR, i.e., P2Y12 reaction unit [PRU]&#x2009;>&#x2009;208). The PCI cohort included participants undergoing PCI on clopidogrel-based dual antiplatelet therapy. The primary outcome was 1-year MACE, defined as the composite of cardiovascular death, myocardial infarction (MI), ischemic stroke, or stent thrombosis. Data on clinically significant bleeding and CYP2C19 genotyping alleles were collected. The PD and PCI cohorts included 728 (32.1% Black) and 2,770 (20.5% Black) participants, respectively. Black participants had higher PRU levels (184 [IQR 128-234] vs. 144 [IQR 88-195]; P&#x2009;<&#x2009;0.001) and higher prevalence of HPR (39.3% vs. 20.6%; P&#x2009;<&#x2009;0.001). Independent predictors of HPR included Black race, hemoglobin levels, and presence of CYP2C19 loss-of-function allele. In the PCI cohort, Black participants had a higher risk of MACE (HR 1.47; 95% CI 1.02-2.11; P&#x2009;=&#x2009;0.037), primarily driven by MI (HR 1.71; 95% CI 1.09-2.67; P&#x2009;=&#x2009;0.019), with no significant difference in clinically significant bleeding (HR 1.08; 95% CI 0.65-1.80; P&#x2009;=&#x2009;0.768). Black participants on clopidogrel exhibit higher platelet reactivity, increased rates of HPR, and an elevated risk of MACE within 1 year after PCI, without significant differences in bleeding compared to non-Black participants.

Vimentin loss inhibits DNA damage responses and promotes cancer cell survival.

Vimentin intermediate filaments are a hallmark of aggressive tumours and are widely linked to invasion and EMT, yet how vimentin-dependent mechanics shape genome maintenance and therapy response is unclear. Here we show that vimentin, particularly under compressive load, promotes DNA repair competence. In contrast, vimentin-negative cells show impaired DNA damage sensing and downstream signaling, ultimately leading to decreased apoptosis and promoting cell survival under genotoxic stress at the expense of genomic stability. Using controlled cell compression together with genetic and pharmacological perturbations, we find that loss of vimentin in glioblastoma cells limits the expression and activity of core repair pathways because of induced nuclear mechanical compression. Relieving nuclear compression restores DNA damage accumulation and repair kinetics. Functionally, suppression of DNA damage responses enhances survival after clinically relevant DNA-damaging treatments, including temozolomide, X-Ray radiation and cell invasion through tight spaces. These findings invert the prevailing view that vimentin's contribution to tumour progression stems from enhanced migration and identify a mechanochemical vimentin-nucleus axis that tunes DNA damage responses to favor therapy tolerance and genome evolution.

IDH2 clonal hematopoiesis and IKAROS loss cooperate in a B-ALL subtype after lenalidomide therapy for multiple myeloma.

Lenalidomide, a maintenance treatment in multiple myeloma first-line therapy, increases the risk of secondary malignancies, including B-cell precursor acute lymphoblastic leukemia (B-ALL). We present a comprehensive molecular characterization of 57 patients with lenalidomide-associated B-ALL (LenB-ALL), revealing 3 mutational subgroups: (1) TP53mt (30%); (2) IDH2mt (p.R140Q) (23%); and (3) other, including NRAS/KRASmt. Remarkably, IDH2 R140Q mutations were highly enriched in LenB-ALL compared with those in primary B-ALL (P< .001). Furthermore, IKZF1 intragenic deletions, often subclonal and likely RAG recombinase-mediated, were observed in 54% (7/13) of IDH2mt patients with LenB-ALL. IDH2 mutations were not restricted to the leukemic clone: they persisted during measurable residual disease-negative remission and were identified in lymphoid as well as myeloid cell populations using fluorescence-activated cell sorting and single-cell RNA sequencing. This indicates a preleukemic origin of the IDH2 mutation within the context of clonal hematopoiesis. Transcriptomic and DNA methylation analyses revealed a distinct gene expression profile and a DNA hypermethylation phenotype in IDH2mt LenB-ALL, including IDH2mt-specific as well as lenalidomide-associated features. We propose that lenalidomide promotes the expansion of IDH2-mutated clonal hematopoiesis and, via IKAROS downregulation, induces a maturation arrest at the B-cell precursor stage. Subsequent genetic or epigenetic alterations render leukemogenesis independent of ongoing lenalidomide exposure. All these data define IDH2mt B-ALL as a distinct molecular subtype that is markedly overrepresented after lenalidomide treatment and highlight clonal hematopoiesis as a key contributing factor in the development of LenB-ALL.

Efficacy and Safety of Anti-Obesity Medications for Weight Loss Maintenance in Adults With Overweight or Obesity: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

AIMS: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of anti-obesity medications (AOMs) for long-term weight maintenance following initial weight loss in adults with overweight or obesity. METHODS: We searched PubMed, Embase, Web of Science and the Cochrane Library from inception to 31 October 2025. Eligible studies were randomised controlled trials (RCTs) comparing AOMs with placebo during the weight-maintenance phase in adults with overweight or obesity after initial weight loss achieved through lifestyle, dietary, surgical or pharmacological interventions. Outcomes included anthropometric indices, cardiometabolic measures, safety endpoints, quality of life and neuropsychiatric adverse events. Weighted mean differences (WMDs) and odds ratios (ORs), each with 95% confidence intervals (CIs), were pooled for continuous and categorical outcomes, respectively, using fixed-effect or random-effects models as appropriate. Risk of bias was assessed using the Cochrane RoB 2 tool, and certainty of evidence was evaluated using the GRADE framework. The protocol was registered with PROSPERO (CRD420261293040). RESULTS: A total of 12 RCTs comprising 4915 participants met the inclusion criteria. Compared with placebo, AOM therapy during the weight-maintenance phase was associated with prevention of weight regain and additional improvements in anthropometric and cardiometabolic outcomes. AOMs led to further reductions in body weight (BW, WMD: -8.68&#x2009;kg, 95% CI: -13.25 to -4.11), waist circumference (WC, WMD: -7.16&#x2009;cm, 95% CI: -10.34 to -3.98) and body mass index (BMI, WMD: -3.58&#x2009;kg/m2, 95% CI: -5.69 to -1.46). Additional benefits were observed for triglycerides, total cholesterol, low-density lipoprotein cholesterol, systolic blood pressure and diastolic blood pressure. Gastrointestinal adverse events were more common with AOMs, whereas serious adverse events were not significantly increased. Neuropsychiatric adverse events were generally comparable between groups, and available quality-of-life measures favoured AOM treatment. CONCLUSIONS: AOM therapy during the weight-maintenance phase can help prevent weight regain, provide further reductions in body weight and improve cardiometabolic risk factors in adults with overweight or obesity. Gastrointestinal adverse events were more common with AOMs, whereas serious adverse events were not significantly increased. Further long-term trials are needed to clarify optimal treatment strategies and safety.

Changes in weight and metabolic health during and after cessation of a time-restricted feeding plus aerobic training in Swiss mice fed a high-fat diet.

Obesity is a chronic disease, representing a significant health problem worldwide. Unhealthy eating habits and sedentarism are key contributors to the development of obesity. Dietary and exercise strategies are the first-line therapies for weight loss or maintenance and have proven effective in controlling weight. However, long-term adherence is challenging, and rapid weight regain often follows intervention cessation. In mice, time-restricted feeding (TRF) and exercise (EXE) independently prevent weight gain and maintain metabolic health, yet weight regain is observed upon cessation. Whether combining TRF and EXE provides longer-lasting benefits remains unclear. Here, we assessed weight and metabolic parameters in Swiss male mice fed with a high-fat diet (HFD) during an 8-wk intervention of TRF (8-h food access in the active phase) or TRF combined with EXE (60-min treadmill running daily) and after cessation and transfer to ad libitum feeding. TRF and EXE interventions successfully mitigate weight gain, improve glycemic homeostasis, and attenuate lipid accumulation in the liver and adipose tissue hypertrophy compared to mice fed HFD ad libitum. However, cessation of both strategies led to rapid weight regain, impaired glycemic control, and increased circulating lipid levels. Although the combination of TRF and EXE led to the lowest body weight and best metabolic health, this group showed no protection against the metabolic impairments observed after TRF cessation alone. In conclusion, TRF and EXE are complementary strategies for managing metabolic health, but cessation of these interventions leads to rapid weight regain and metabolic deterioration, with only partial preservation of select metabolic adaptations. These findings underscore the critical need for sustained adherence to lifestyle interventions in obesity management.NEW & NOTEWORTHY This study demonstrates that combining time-restricted feeding with aerobic training improves weight and metabolic health in Swiss mice fed a high-fat diet. Importantly, we show that most metabolic benefits are lost after intervention cessation. However, insulin sensitivity and aspects of hepatic lipid metabolism are partially maintained after cessation of the intervention. These findings provide new insight into the durability of metabolic improvements induced by lifestyle interventions and highlight the potential of combined dietary and exercise strategies to counteract diet-induced obesity and metabolic dysfunction.

Decoding context-dependent sirtuin pharmacology in cancer: Metabolic-epigenetic switches and precision therapeutic targeting.

Sirtuins (SIRT1-SIRT7) are a family of NAD+-dependent lysine deacetylases that possess mono-ADP-ribosyltransferase activity and integrate cellular metabolic status with chromatin regulation, genome maintenance, redox homeostasis, immune responses, and adaptation to cancer therapies. Their translational value has been obscured by a recurring paradox: the same isoform may constrain malignant transformation in one setting yet support metastatic competence, stemness, immune evasion, or drug resistance in another. This review reframes that paradox as a measurable problem of context. We define a SIRT context code in which NAD+ availability and compartmentalization, subcellular localization, PTM state, chromatin occupancy, oncogenic genotype, cell lineage, and tumor microenvironment jointly determine sirtuin output. Using recent mechanistic and translational evidence, we summarize how sirtuins regulate metabolic switching, histone acetylation and lactylation, genome stability, cancer-associated fibroblast programs, regulatory T-cell enrichment, cancer stem-cell plasticity, angiogenesis, and resistance to DNA-damaging, targeted, and immune therapies. We further argue that successful sirtuin pharmacology will require context matching rather than indiscriminate activation or inhibition. Priorities include spatial and single-cell biomarker discovery, compartment-specific NAD+ measurements, PTM-resolved activity assays, structure-guided isoform-selective agents, and degrader strategies targeting non-catalytic scaffolding functions. Sirtuins should therefore be viewed as metabolic-epigenetic decision nodes rather than fixed oncogenes or tumor suppressors. However, the evidence remains predominantly preclinical, and our search identified no clinical-stage oncology trials of direct sirtuin modulators using prospective biomarker stratification, underscoring that this framework remains translationally aspirational rather than clinically validated.
