Thrombocytopenia is associated with an increased risk of bleeding. Hence, treatment of acute VTE with anticoagulation is challenging in patients with cancer and thrombocytopenia. Data are limited in the management of this condition, and there are no randomized controlled trials (RCTs) available. The strategies for anticoagulation in patients with thrombocytopenia and cancer-associated thrombosis pilot trial (NCT05255003) is an open-label pilot RCT to evaluate the feasibility of a full-scale trial in this population. Adult patients with acute cancer-associated thrombosis within 14 days and thrombocytopenia (platelet count < 50,000/μL) are randomly assigned to 2 treatment arms as follows: (1) modified-dose low-molecular-weight heparin based on a predefined regimen to adjust dose by platelet count; or (2) platelet transfusion with a higher dose low-molecular-weight heparin regimen. The primary feasibility outcome is the overall average number of patients recruited per month. The main clinical outcomes include clinically relevant bleeding events (composite of major bleeding and clinically relevant nonmajor bleeding) and objectively confirmed recurrent VTE. This trial has the potential to define care in patients with acute cancer-associated thrombosis and thrombocytopenia. In this article, we present the rationale and design of the pilot trial and highlight several unique aspects of the study.</div></div>","PeriodicalId":20893,"journal":{"name":"Research and Practice in Thrombosis and Haemostasis","volume":"9 4","pages":"Article 102898"},"PeriodicalIF":3.4,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hemophilia A and B are inherited genetic disorders caused by mutations in the <em>FVIII</em> and <em>FIX</em> genes, respectively. Traditional treatments for hemophilia have included intravenous plasma, factor concentrates, and nonfactor therapies that require lifelong prophylaxis and carry risks of factor inhibitor development. Gene therapy offers a novel solution by delivering functional <em>FVIII</em> or <em>FIX</em> genes via adeno-associated virus vectors, which enable the production of the missing factors. Clinical outcomes have shown promise through gene therapies like valoctocogene roxaparvovec for hemophilia A and etranacogene dezaparvovec and fidanacogene elaparvovec for hemophilia B. Each therapy has demonstrated efficacy in reducing bleeding rates and maintaining factor activity. However, challenges such as hepatotoxicity, immune response, and durability of gene expression persist. Future advancements aim to expand eligibility, achieve sustained expression, and minimize adverse effects. Current trials are exploring new vectors, transgenes, and methods to overcome existing limitations.
