However, dysregulation of this axis contributes to the pathogenesis of numerous disorders, highlighting CXCR4 inhibition as a promising therapeutic strategy. Mavorixafor, the first orally available small-molecule CXCR4 antagonist, recently received FDA approval for WHIM syndrome (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis) and is currently being developed for additional indications. Despite extensive research on CXCR4 biology, a comprehensive analysis of mavorixafor’s pharmacologic profiles and its performance in preclinical and clinical settings is lacking. This systematic review synthesizes the pharmacology, efficacy, and safety of mavorixafor, summarizing evidence from various sources, including PubMed/MEDLINE, Web of Science, Google Scholar, conference proceedings, clinicaltrials.gov, and FDA resources. Mavorixafor demonstrates potent CXCR4 antagonism, rapid oral absorption, and a long half-life, enabling once-daily dosing. Clinically, it has been shown to increase neutrophil counts and reduce infection rates, contributing to its approval for WHIM syndrome. Early clinical studies in chronic neutropenia indicate sustained neutrophil elevation and decreased dependence on G-CSF. Additionally, emerging data suggest potential benefits in specific malignancies and its utility in mobilizing hematopoietic stem and progenitor cells, as well as in other immune-mediated disorders related to CXCR4 dysregulation. Furthermore, this review positions mavorixafor within the broader CXCR4-targeted therapeutic landscape, identifying current research gaps and suggesting directions for future studies. In conclusion, by integrating mechanistic insights with preclinical and clinical findings, this article highlights mavorixafor’s promise as a targeted therapy with the potential to transform treatment paradigms for CXCR4-driven diseases.</div></div>","PeriodicalId":54260,"journal":{"name":"Current Research in Translational Medicine","volume":"74 2","pages":"Article 103584"},"PeriodicalIF":3.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147624817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sequential conditioning, combining cytoreductive chemotherapy with reduced-intensity conditioning, was designed to reduce toxicity while preserving efficacy in frail patients. While numerous studies have evaluated different sequential regimens, the impact of rest period duration between the two phases remains unexplored. This bicentric retrospective study analyzed 82 allo-HSCT between 2013 and 2021, in patients with high-risk myeloid malignancies (median age 58 years). Short-bridge-to-transplant regimens (SBTT, n=44) with rest periods of 7 days or less, including the well-known FLAMSA-RIC, were compared to long-bridge-to-transplant regimens (LBTT, n=38) with rest periods longer than 7 days. After a median follow-up of 33 months, rest period duration did not significantly affect progression-free survival (PFS), overall survival, relapse incidence or non-relapse mortality (NRM). Two-year PFS was 35.1% for SBTT versus 57.2% for LBTT (<em>aHR</em> 1.62; <em>P</em>=0.13). However, measurable residual disease-free survival (MRD-FS) was significantly improved with LBTT (<em>aHR</em> 2.15; <em>P</em>=0.02). Despite longer median aplasia, LBTT showed comparable complications and enabled more intensive chemotherapy without increased NRM. LBTT appears feasible and not inferior to SBTT, with a signal of improved MRD control that may reflect better temporal separation and management of treatment-related toxicities, safe delivery of higher-dose or more intensive chemotherapy, and potential leukemic cell-cycle synchronization effects. While center-specific practices and regimen heterogeneity limit definitive conclusions, these hypothesis-generating findings highlight an underexplored dimension of sequential conditioning and warrant further investigation in larger prospective studies.</div></div>","PeriodicalId":54260,"journal":{"name":"Current Research in Translational Medicine","volume":"74 2","pages":"Article 103586"},"PeriodicalIF":3.0,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147657165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
