    Notable Efficacy of Co-Treatment with FHD-286, a Dual BRG1/BRM ATP-Ase Inhibitor, and Menin or BET Inhibitor, Decitabine or Venetoclax Against AML with MLL-r or Mutant NPM1 (ASH 2023)
    BRG1 (SMARCA4) and BRM (SMARCA2) are the core ATPase within the multi-protein, ATP-dependent, chromatin remodeling BAF complexes that regulate gene transcription. Finally, co-treatment with FHD-286 and OTX015 or SNDX-5613 (oral gavage) was significantly more effective than each drug alone in reducing the AML burden and overall survival of mice engrafted with a separate PDX model of AML cells with mtNPM1 and FLT3-ITD, without significant toxicity. These findings demonstrate the pre-clinical efficacy of FHD-286-based rational combinations and underscore their promise against AML with MLL1r or mtNPM1.

    The dual BRM/BRG1 (SMARCA2/4) inhibitor FHD-286 induces differentiation in preclinical models of AML (AACR 2023)
    Expanding on these findings, we have also demonstrated synergistic activity with multiple combination partners, including cytarabine and decitabine, in vitro. Elaboration of this in both CDX and PDX in vivo models also shows significant survival benefit in difficult to treat mutational backgrounds. Taken together, these findings suggest that FHD-286 is able to target blast progenitor populations that are heavily BRM/BRG1-dependent, and that combination with standard of care agents can achieve profound, mutationally agnostic antitumor activity in AML.

    Pre-Clinical Efficacy of Targeting Baf Complexes through Inhibition of the Dual Atpases BRG1 and BRM By FHD-286 in Cellular Models of AML of Diverse Genetic Background (ASH 2022)
    Based on these observations, and clinical efficacy of the combination of venetoclax and decitabine/azacitidine, we determined the in vitro lethal activity of co-treatment with FHD-286 and venetoclax or decitabine against AML cell lines and PD AML cells. Additionally, co-treatment with FHD-286 and venetoclax or decitabine or OTX015, as compared to each drug alone or vehicle control, significantly reduced the AML burden and improved median and overall survival of the immune-depleted mice, without inducing significant toxicity. Taken together, these findings highlight the promise of FHD-286 treatment alone and in rational combinations in exerting significant anti-AML efficacy against cellular models of AML, especially those with MLL-r, mtNPM1 or chromosome 3q26 lesions and EVI1 overexpression.

    Synergistic efficacy of the BRM/BRG1 ATPase inhibitor, FHD-286, and anti-PD-1 antibody in mouse syngeneic tumor models (SITC 2022)
    FHD-286 increased MHCI expression on B16F10 cells, and increases in IFNγ and Th1-type chemokine CXCL10 levels were observed in immunocompetent mice following treatment, suggesting that combinatorial activity may result from effects on both the tumor and the immune system. Conclusions FHD-286 has the potential to sensitize tumor to immune-checkpoint inhibition and represents a novel combination approach for cancer immunotherapy.

    Modulation of SPI1 transcriptional program contributes to the preclinical anti-tumor activity of SMARCA4/SMARCA2 ATPase inhibitors in AML (AACR 2022)
    Using in vivo mouse models of AML, we demonstrate dose-dependent tumor growth inhibition and pharmacodynamic modulation of SPI1 target genes. Together, these data suggest that modulation of SPI1 function may, in part, provide a mechanistic basis for the clinical development of FHD-286 in AML.

    SWI/SNF Complex-deficient Undifferentiated Carcinoma of the Gastrointestinal Tract: Clinicopathologic Study of 30 Cases With an Emphasis on Variable Morphology, Immune Features, and the Prognostic Significance of Different SMARCA4 and SMARCA2 Subunit Deficiencies. (PubMed, Am J Surg Pathol)
    Specifically, patients with loss of SMARCA4 expression had the worst overall survival (P=0.028) and disease-free survival (P=0.006) rates, compared with those with SMARCA4 expression. The loss or decreased expression of epithelial markers is thus common in SWI/SNF complex-deficient undifferentiated carcinoma of the gastrointestinal tract, and loss of SMARCA4 correlates with poor prognosis.

    A novel SMARCA2-CREM fusion: expanding the molecular spectrum of intracranial mesenchymal tumors beyond the FET genes. (PubMed, Acta Neuropathol Commun)
    Interestingly, the current case did not cluster with IMT, FET-CREB fusion-positive but rather presented histopathological (clear cell morphology with signs of malignancy), clinical (with a dismal course with several recurrences, metastases and finally the patient's death), genetic (fusion implicating the CREM gene), and epigenetic (DNA-methylation profiling) similarities with our previously reported clear cell sarcoma-like tumor of the central nervous system. Our results added data suggesting that different clinical and histomolecular tumor subtypes or grades seem to be included within the terminology "IMT, FET-CREB fusion-positive", and that further series of cases are needed to better characterize them.

    SMARCA4/2 loss inhibits chemotherapy-induced apoptosis by restricting IP3R3-mediated Ca flux to mitochondria. (PubMed, Nat Commun)
    Reactivation of SMARCA2 by a histone deacetylase inhibitor rescues IP3R3 expression and enhances cisplatin response in SMARCA4/2-deficient cancer cells both in vitro and in vivo. Our findings elucidate the contribution of SMARCA4/2 to Ca-dependent apoptosis induction, which may be exploited to enhance chemotherapy response in SMARCA4/2-deficient cancers.

    However, the abundance of tumor infiltrating lymphocytes suggests an immunogenic tumor microenvironment, which may be a result of the transcriptional program regulated by SMARCA4. We seek to raise awareness of this highly aggressive entity with potential therapeutic implications.

    Comprehensive Immunohistochemical Study of the SWI/SNF Complex Expression Status in Gastric Cancer Reveals an Adverse Prognosis of SWI/SNF Deficiency in Genomically Stable Gastric Carcinomas. (PubMed, Cancers (Basel))
    SWI/SNF aberration emerged as an independent negative prognostic factor for overall survival in genomically stable patients in analogy to TCGA. In conclusion, determination of SWI/SNF status could be suggested in routine diagnostics in genomically stable tumors to identify patients who might benefit from new therapeutic options.

    Infrequent loss of SMARCA4, SMARCA2, and SMARCB1 expression in uterine mesenchymal tumors. (PubMed, Hum Pathol)
    SMARCA4 immunohistochemistry has potential in the diagnosis of SMARCA4-DUS with the exclusion of some tumors showing its deficiency, such as endometrial stromal sarcoma and undifferentiated carcinoma. Undifferentiated carcinoma may show an indistinguishable morphology and immunophenotype from SMARCA4-DUS, and, thus, a molecular analysis is required for their distinction in diagnostic practice.

    The SWI/SNF complex regulates the expression of miR-222, a tumor suppressor microRNA in lung adenocarcinoma. (PubMed, Hum Mol Genet)
    Finally, we showed that the miR-222 enhancer region resides in a topologically associated domain that does not contain any cancer-related protein-coding genes, suggesting that miR-222 may be involved in exerting the tumor suppressor role of SMARCA4. Overall, this study highlights the relevant role of the SWI/SNF complex in regulating the non-coding genome, opening new insights into the pathogenesis of LUAD.
