The primary endpoint was overall survival (OS); secondary endpoints included event-free survival (EFS) and complete remission (CR) rate. As of June 30, 2020 (interim analysis: 32.2 months after study initiation), 234 patients were randomized (gilteritinib, n = 116; SC, n = 118). Median OS was significantly longer with gilteritinib versus SC (9.6 vs. 5.0 months; HR 0.566 [95% CI: 0.392, 0.818]; p = 0.00211) with a median follow-up of 10.3 months. Median EFS was also significantly longer with gilteritinib (2.8 vs. 0.6 months; HR 0.551 [95% CI: 0.395, 0.769]; p = 0.00004). CR rates with gilteritinib and SC were 16.4% and 10.2%, respectively; composite CR rates were 50.0% and 20.3%, respectively. Exposure-adjusted grade ≥3 adverse event (AE) rates were lower with gilteritinib (58.38 events/patient-year [E/PY]) versus SC (168.30 E/PY). Common AEs with gilteritinib were anemia (77.9%) and thrombocytopenia (45.1%). Gilteritinib plasma concentration peaked ~4 h postdose; ~3-fold accumulation occurred with multiple dosing.

To determine which processes are active in (relapsed) ALL and how they behave during disease progression before and after therapy, we performed whole genome sequencing on 97 tumor samples of 29 multiply relapsed ALL patients. Mutational load increased upon relapse in 28 patients and upon every subsequent relapse in 22 patients. In addition to two clock-like mutational processes, we identified UV-like damage, APOBEC activity, reactive oxygen species, thiopurine-associated damage and an unknown therapy component as drivers of mutagenesis. Mutational processes often affected patients over longer time periods, but could also occur in isolated events, suggesting the requirement of additional triggers. Thiopurine exposure was the most prominent source of new mutations in relapse, affecting over half of the studied patients in first and/or later relapse and causing potential relapse-driving mutations in multiple patients. Our data demonstrate that multiple mutational processes frequently act in parallel as prominent secondary drivers with dynamic activity during ALL development and progression.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":null,"pages":null},"PeriodicalIF":12.8,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41375-024-02403-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142133167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tumor-associated macrophages (TAMs) within the tumor microenvironment often display a pro-tumor phenotype and correlate with tumor proliferation, survival, and therapy resistance. IL-10 is a key immunosuppressive cytokine that leads to recruitment and development of TAMs. In this study, we investigated the role of IL-10 in MM TAM development as well as the therapeutic application of IL-10/IL-10R/STAT3 signaling inhibition. We demonstrated that IL-10 is overexpressed in MM BM and mediates M2-like polarization of TAMs in patient BM, 3D co-cultures in vitro, and mouse models. In turn, TAMs promote MM proliferation and drug resistance, both in vitro and in vivo. Moreover, inhibition of IL-10/IL-10R/STAT3 axis using a blocking IL-10R monoclonal antibody and STAT3 protein degrader/PROTAC prevented M2 polarization of TAMs and the consequent TAM-induced proliferation of MM, and re-sensitized MM to therapy, in vitro and in vivo. Therefore, our findings suggest that inhibition of IL-10/IL-10R/STAT3 axis is a novel therapeutic strategy with monotherapy efficacy and can be further combined with current anti-MM therapy, such as immunomodulatory drugs, to overcome drug resistance. Future investigation is warranted to evaluate the potential of such therapy in MM patients.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":null,"pages":null},"PeriodicalIF":12.8,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41375-024-02391-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142100841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can cause cancer-promoting alterations, such as loss of sequences for tumor-suppressor genes, formation of oncogenic fusions, and oncogene amplifications. We investigated the genetic background and clinical significance of cth in childhood T-cell acute lymphoblastic leukemia (T-ALL) patients. For this purpose, whole-genome copy number alterations were analyzed in 173 children with newly diagnosed T-ALL using high-density microarrays. Cth was identified in 10 T-ALL samples (5.78%). In six of them, cth occurred in a constitutional background of Nijmegen breakage syndrome (n = 5) or Li-Fraumeni syndrome (n = 1). Cth generated alterations, including deletions of CDKN2A/B (n = 4) and EZH2 (n = 4), amplifications of CDK6 (n = 2), and NUP214::ABL1 and TFG::GPR128 fusions. Cth-positive leukemias exhibited deletions involving the tumor-suppressor genes RB1 (n = 3), TP53 (n = 1) and MED12 (n = 2). Cth-positive T-ALL patients had a lower probability of 5-year overall survival (OS) [0.56 vs. 0.81; hazard ratio (HR) = 4.14 (1.42–12.02) p = 0.017] as did 5-year event-free survival [0.45 vs. 0.74; HR = 3.91 (1.52–10.08); p = 0.012]. Chromothripsis is an infrequent genomic phenomenon in pediatric T-ALL but is significantly associated with cancer-predisposing syndromes and may associate with inferior prognosis.","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":null,"pages":null},"PeriodicalIF":12.8,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41375-024-02370-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142080798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
