Tagraxofusp's most significant success has come from studies involving patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN), an aggressive disease that is usually refractory to conventional chemotherapy. Tagraxofusp had an acceptable safety profile and high efficacy in early phase I/II studies on patients with BPDCN. Another phase II study confirmed the good response rates, resulting in Food and Drugs Administration and European Medicine Agency approval of tagraxofusp for the treatment of BPDCN. Considering its high efficacy and its manageable safety profile, tagraxofusp has been suddenly explored in other myeloid malignancies with high expression of cell surface CD123, both in monotherapy or combination strategies. The triplet tagraxofusp-azacytidine-venetoclax appears to be of particular interest among these combinations. Furthermore, combination strategies may be used to overcome tagraxofusp resistance. The downregulation of DPH1 (diphthamide biosynthesis 1), the enzyme responsible for the conversion of histidine 715 on eEF2 to diphthamide, which is then the direct target of ADP ribosylation DT, is typically associated with this resistance phenomenon. It has been discovered that azacitidine can reverse DHP1 expression and restore sensitivity to tagraxofusp. In conclusion, the success of tagraxofusp in BPDCN paved the way for its application even in other CD123-positive malignancies.

Despite advances, treatment resistance and patient relapse remain challenging issues. Our study aimed to scrutinize gene expression distinctions between DLBCL and FL, employing a cohort of 53 DLBCL and 104 FL samples that underwent rigorous screening for genetic anomalies. The NanoString nCounter assay evaluated 730 cancer-associated genes, focusing on densely tumorous areas in diagnostic samples. Employing the Lymph2Cx method, we determined the cell-of-origin (COO) for DLBCL cases. Our meticulous analysis, facilitated by Qlucore Omics Explorer software, unveiled a substantial 37% of genes with significantly differential expression patterns between DLBCL and FL, pointing to nuanced mechanistic disparities. Investigating the impact of FL disease stage and DLBCL COO on gene expression yielded minimal differences, prompting us to direct our attention to consistently divergent genes in DLBCL. Intriguingly, our Gene Set Enrichment Analysis spotlighted 21% of these divergent genes, converging on the DNA damage response (DDR) pathway, vital for cell survival and cancer evolution. Strong positive correlations among most DDR genes were noted, with key genes like <i>BRCA1</i>, <i>FANCA</i>, <i>FEN1</i>, <i>PLOD1</i>, <i>PCNA</i>, and <i>RAD51</i> distinctly upregulated in DLBCL compared to FL and normal tissue controls. These findings were subsequently validated using RNA seq data on normal controls and DLBCL samples from public databases like The Cancer Genome Atlas (TCGA) and the Genotype-Tissue Expression (GTEx) databases, enhancing the robustness of our results. Considering the established significance of these DDR genes in solid cancer therapies, our study underscores their potential applicability in DLBCL treatment strategies.
