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.

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.

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.

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.

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.

Classic induction treatment did not result in remission of MS, confirming the poor prognosis and resulting in a salvage treatment before planned allogeneic stem cell transplantation. Further studies are needed to define the optimal therapeutic strategy in this entity.

We also revealed that CD123-positive AML/MS patients had a significantly poorer outcome than BPDCN and that 12% (24/205) of the cases were non-BPDCN even if all three conventional markers were positive, thus clarifying the risk of diagnosing BPDCN without more specific markers. In addition, histopathological features, such as the reticular pattern, which is not seen in BPDCN and suggests AML/MS, were also identified.
