BRD4 inhibitor reduces exhaustion and blocks terminal differentiation in CAR-T cells by modulating BATF and EGR1. (PubMed, Biomark Res)
Our study reveals that a BRD4 inhibitor can reduce CAR-T cell exhaustion and block exhausted T cell terminal differentiation by downregulating BATF activity and expression together with upregulating EGR1 activity and expression, presenting an approach for improving the effectiveness of CAR-T cell therapy.

Clinical Characteristics of CD4-CD56+ Blastic Plasmacytoid Dendritic Cell Neoplasm (PubMed, Zhongguo Shi Yan Xue Ye Xue Za Zhi)
CD4-CD56+ BPDCN is very rare and easily misdiagnosed as other hematological tumors with poor prognosis. Acute lymphoblastic leukemia or lymphomatoid therapy should be used first to improve the poor prognosis.

Bortezomib suppresses acute myelogenous leukaemia stem-like KG-1a cells via NF-κB inhibition and the induction of oxidative stress. (PubMed, J Cell Mol Med)
BTZ also increased mitochondrial superoxide levels in KG-1a cells, and BTZ-induced apoptosis was partially prevented by pretreatment with the antioxidant N-acetylcysteine, indicating that BTZ induces oxidative stress-mediated apoptosis in KG-1a cells. At a dosage of 0.1 mg/kg every other day for 2 weeks, BTZ significantly reduced the percentage of hCD45-positive cells in the bone marrow and peripheral blood of NSG mice engrafted with KG-1a cells with tolerable toxicity. Taken together, these data indicate that the anti-LSC potential of BTZ appears to be an important strategy for AML treatment.

Flotetuzumab as a salvage immunotherapy in advanced CD123-positive hematological malignancies, a phase 1 pilot study. (PubMed, Leuk Lymphoma)
Responses only occurred in Cohort B, with a partial response in one patient with Hodgkin's lymphoma and morphological complete remission in the bone marrow in one patient with blastic plasmacytoid dendritic cell neoplasm. In conclusion, flotetuzumab had a manageable safety profile in advanced CD123-positive hematological malignancies.

Tagraxofusp, a first-in-class CD123-targeted agent: Five-year postapproval comprehensive review of the literature. (PubMed, Cancer)
The successful targeting of CD123 in BPDCN has also encouraged research into a variety of other CD123-positive hematological neoplasms, including acute myeloid leukemia (AML), and informed the development of other novel agents targeting CD123. This review examines the clinical data leading to the development and approval of tagraxofusp in BPDCN, how it is being used in combination to improve outcomes in BPDCN and AML, and its developing role in other hematological malignancies.

Pivekimab sunirine showed single-agent activity across multiple doses, with a recommended phase 2 dose of 0·045 mg/kg once every 3 weeks. These findings led to a phase 1b/2 study of pivekimab sunirine plus azacitidine and venetoclax in patients with CD123-positive acute myeloid leukaemia.

Phase 1b trial of tagraxofusp in combination with azacitidine with or without venetoclax in acute myeloid leukemia. (PubMed, Blood Adv)
Median overall survival and progression-free survival were 14 months (95% CI, 9.5-NA) and 8.5 months (95% CI, 5.1-NA), respectively. In summary, TAG-AZA-VEN shows encouraging safety and activity in high-risk AML, including TP53-mutated disease, supporting further clinical development of TAG combinations.

Tagraxofusp Shows Promising Anti-Tumoral Efficacy in Preclinical in Vitro Models of Myelofibrosis, Both As a Single Agent and in Combination with Janus Kinase Inhibitors (ASH 2023)
The role of the JAK/Signal transducer and activator of transcriptions (STAT) pathway in MF has led to the recent approval of three different JAK2 inhibitors (ruxolitinib, pacritinib, and fedratinib) for MF treatment. Our studies showed high sensitivity of MF cell lines to tagraxofusp as a single agent, which is expected given phase 2 results demonstrated clinical efficacy of single-agent tagraxofusp in R/R MF (Yacoub et al. ASH 2021). In addition, synergism was observed in combination with JAK inhibitors.

Safety studies in cynomolgus monkey support the clinical development of AZD9829, a promising therapeutic candidate for the treatment of AML across the spectrum of CD123-expression and genetic mutations.

Diagnostic Challenges in the Leukemia Phase of Blastic Plasmacytoid Dendritic Cell Neoplasm without Skin Involvement: A Clinical and Pathological Study (ASH 2023)
Only one cycle of decitabine + CAG was given and 5 months later, the disease progressed to the leukemia phase...The latter case had ASXL1 and TET2 mutations detected by NGS analysis, achieved complete remission after receiving venetoclax + azacitidine for one cycle, followed by intermittent venoclax +demethylation agent or low-dose chemotherapy maintenance treatment and live for more than two years now... BPDCN without skin lesions is clinically rare, and its diagnosis is challenging. Comprehensive immunophenotyping and cautious interpretation of immunohistochemistry results such as dim lysozyme expression are crucial. Venetoclax-containing regimens have shown promising therapeutic effects.

IRF8 in Conjunction With CD123 and CD20 to Distinguish Lupus Erythematosus Panniculitis From Subcutaneous Panniculitis-like T-Cell Lymphoma. (PubMed, Am J Surg Pathol)
However, a panel combining IRF8, CD123, and CD20, with at least 1 positive marker was more accurate than any individual marker by receiver operating characteristic curve analysis. Our study provides a rationale for potentially including IRF8 as part of an immunohistochemical panel composed of other currently available markers used to differentiate LEP from SPTCL.

Venetoclax Synergizes with IMGN632, a Novel CD123-Targeting Antibody Conjugated to a DNA Alkylating Payload, By Suppressing DNA Damage Response and Potentiating Apoptosis in Acute Myeloid Leukemia in Vitro Models (ASH 2023)
Importantly, we previously showed high synergy of IMGN632 combination with BCL-2 inhibitor venetoclax (VEN) and DNA hypomethylating azacytidine (AZA) in AML cell lines and xenograft models (ASH 2020, #617). Together, these results suggest that VEN, apart from its canonical inhibitory effect on anti-apoptotic BCL-2, exerts previously unrecognized ability to suppress DDR program in AML and augments activity of DNA damaging IMGN632. Failure of cells to sustain DDR in the presence of VEN constitutes a key aspect of high efficacy of IMGN/VEN/AZA combination in AML.

Pts had received a median of 2.0 (1.0 –10.0) prior lines of treatment with 13 pts (30.2%) reporting prior hematopoietic stem cell transplantation and 36 pts (83.7%) with prior exposure to venetoclax. SAR'579 was well tolerated up to doses of 6000 µg/kg QW with observed clinical benefit in pts with R/R AML. The results are consistent with the predicted favorable safety profile.

The regimen was well tolerated with no new safety signals, and the addition of PVEK to the AZA-VEN backbone did not appear to meaningfully prolong count recovery.

Functional Characterization and Optimization of Switchable Allogeneic Chimeric Antigen Receptor T Cells for Targeting CD19 and CD20 in B Cell Malignancies (ASH 2023)
A summary of functional characterization data will be presented at the meeting with a focus on the lack of predictability of certain in vitro models and underlying hypotheses. Insights from these studies are now flowing into preclinical development of a novel switchable allogeneic CAR-T cell product candidate targeting CD19 and CD20 in B cell malignancies engineered to fully overcome graft-versus-host disease as well as graft rejection by host T and NK cells.

Tandem bispecific CD123/CLL-1 CAR-T cells exhibit specific cytolytic effector functions against human acute myeloid leukaemia. (PubMed, Eur J Haematol)
CD123/CLL-1 CAR-T cells in tandem can simultaneously target CD123 and CLL-1 on AML cells, demonstrating a significant ability to kill single antigens and multi-target tumour cells. This suggests that CD123/CLL-1 CAR-T cells exhibit significant advantages in the expression of multiple antigens in a wide range of target cells, which may help overcome the challenges posed by tumour heterogeneity and evasion mechanisms.
