Pretreatment CD38 density on tumor cells is an important determinant of mAb efficacy. Several small molecules have been found to increase tumor surface CD38, with the goal of boosting mAb efficacy in a cotreatment strategy. Numerous other CD38-targeting therapeutics are currently in preclinical or clinical development. Here, we sought to extend our currently limited insight into CD38 surface expression by using a multiomics approach. Genome-wide CRISPR interference screens integrated with patient–centered epigenetic analysis confirmed known regulators of <em>CD38</em>, such as RARA, while revealing XBP1 and SPI1 as other key transcription factors governing surface CD38 levels. <em>CD38</em> knockdown followed by cell surface proteomics demonstrated no significant remodeling of the myeloma “surfaceome” after genetically induced loss of this antigen. Integrated transcriptome and surface proteome data confirmed high specificity of all-trans retinoic acid in upregulating CD38, in contrast to the broader effects of azacytidine and panobinostat. Finally, unbiased phosphoproteomics identified inhibition of MAP kinase pathway signaling in tumor cells after daratumumab treatment. Our work provides a resource to design strategies to enhance efficacy of CD38-targeting immunotherapies in myeloma.</p></div>","PeriodicalId":100189,"journal":{"name":"Blood Neoplasia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950328024000256/pdfft?md5=a27e6b08696b724b63d2d012e38a44b2&pid=1-s2.0-S2950328024000256-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141638776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe 40 patients with histiocytic neoplasms who were treated with targeted therapy in 7 tertiary referral hospitals from the Netherlands and Belgium. The cohort comprised of 6 (15%) children and 34 (85%) adults with diverse histiocytoses, including Langerhans cell histiocytosis (LCH; n = 12), Erdheim–Chester disease (n = 14), central nervous system xanthogranuloma (n = 2), Rosai–Dorfman disease (n = 3), histiocytic sarcoma (n = 2), ALK–positive histiocytosis (n = 1), and mixed/unclassifiable histiocytosis (n = 6). Five patients were included in a clinical trial; 35 (88%) received BRAF/MEK inhibitors outside of trials. Among these 35 patients with available follow-up data, median time on targeted treatment was 1.9 years (range, 0.04-5.8 years). Complete or partial responses were observed in 25 of 27 (93%) patients treated for multisystemic and/or solid lesions and 2 of 8 (25%) patients treated for neurodegenerative LCH.

Two patients developed new or progressive neurodegenerative lesions: 1 during and 1 after vemurafenib therapy. At last follow-up, 8 adults had stopped targeted therapy because of toxicity.

We performed a retrospective cohort study of patients with newly diagnosed LBCL treated in a large safety-net hospital system. Between January 2011 and June 2022, 496 patients aged &gt;18 years were diagnosed with LBCL at Harris Health System, Houston, Texas. The median age was 53 years, 75% were uninsured, and 81% were in the most disadvantaged Area Deprivation Index national quartiles. Most (69%) had stage III/IV disease, 44% had poor-risk disease by the Revised International Prognostic Index (R-IPI), and 17% had a history of HIV infection. The median diagnosis-to-treatment interval was 17 days. The median follow-up time was 53.5 months. Among 464 evaluable patients, 66% achieved a complete response, and 11% had a partial response. Of 48 patients, 26 (54%) eligible for cell therapies received them. At 5 years, event-free and overall survival (OS) rates were 57% and 68%, respectively. Factors that affected OS included Hispanic ethnicity (hazard ratio [HR], 0.70; <em>P</em> = .027), R-IPI (HR, 4.67 for poor vs very good risk; <em>P</em> &lt; .001), National Cancer Institute Comorbidity Index (HR, 1.53 per unit increment; <em>P</em> = .003), hemoglobin (HR, 0.89 per unit increment; <em>P</em> = .002), and International Normalized Ratio (HR, 2.17 per unit increment; <em>P</em> = .007). Insurance status was not associated with differences in OS. In our safety-net health system with robust financial assistance programs and limited access to cell therapies, uninsured status was not associated with inferior outcomes. Addressing barriers to care may improve outcomes in other settings.</p></div>","PeriodicalId":100189,"journal":{"name":"Blood Neoplasia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2950328024000207/pdfft?md5=e382f0d8e27c903ab9a7be1a0e9c73ff&pid=1-s2.0-S2950328024000207-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141144995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
