To evaluate the efficacy of a novel histone deacetylase inhibitor, chidamide, in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (CR-CHOP) in the treatment of DEL. The most common grades 3-4 hematologic and nonhematologic toxicity were leukopenia (46.7%) and infection (21%), respectively. This long-term follow-up study indicates that CR-CHOP in untreated DLBCL with the DEL phenotype demonstrates high short-term efficacy and safety as well as promising survival outcomes.

Chidamide combined with (+)-JQ-1 can inhibit the proliferation of MLL-r AML cells, inhibit the initiation of protective self-repair of these leukemia cells by inhibiting the DNA damage response pathway, and ultimately increase the apoptosis of these cells, but non- MLL-r AML cells have no similar results.

Our study suggested that chidamide exerts an antitumor effect on T-LBL/ALL and promotes a more inflammatory form of cell death via the FOXO1/GSDME axis, which provides a novel choice of targeted therapy for patients with T-LBL/ALL.

Among them, compound 20 exhibited potential inhibitory activity on HDAC1, and demonstrated notable potency against RPMI-8226 cells with an IC50 value of 2.89 ± 0.43 μM, which was better than chidamide (IC50 = 10.23 ± 1.02 μM)...The ADME parameters calculation showed that 20 possesses remarkable theoretical drug-likeness properties. Taken together, these results suggested that 20 is worthy of further exploration as a potential HDAC-targeted anticancer drug candidate.

The joint experimental results showed that overexpression of SLC7A11 or downregulation of miR-223-5p alleviated the promoting effect of silencing HDAC10 on ferroptosis in NSCLC cells. HDAC10 inhibits miR-223-5p expression through H3K9ac deacetylation of the miR-223-5p promoter, thereby promoting SLC7A11 expression and inhibiting ferroptosis in NSCLC cells.

Importantly, tumor growth inhibition by HDAC inhibition was dependent on SULF1 expression in CAFs, and CRC patients with more SULF1+ CAFs were more responsive to treatment with the HDAC inhibitor chidamide. Collectively, these findings unveil the critical role of SULF1+ CAFs in CRC and provide a strategy to stratify CRC patients for HDAC inhibitor treatment.

Here we report chidamide maintenance therapy after allo-HSCT in patients with SET-NUP214 fusion positive T-ALL. Both patients improved effectively during follow-up, confirming the efficacy of chidamide in improving the condition of these patients and may provide valuable clinical information for the treatment of this rare and understudied disease.

We conducted an open-label, phase 2 nonrandomised, externally controlled study to evaluate the efficacy and safety of targeted agents plus CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) (CHOPX) for PTCL in the front-line setting...Specific targeted agents were added from Cycle 2, decitabine if TP53 mut, azacytidine if TET2/KMT2D mut, tucidinostat if CREBBP/EP300 mut, and lenalidomide if without mutations above...Biomarker-driven therapeutic strategy is feasible and may lead to promising efficacy specifically toward molecular features in PTCL. This study was supported by the National Key Research and Development Program (2022YFC2502600) and the General Program of the Shanghai Municipal Health Commission (202040400).

Furthermore, we found that lenalidomide targeted BCL6 degradation through the ubiquitination pathway and restore the sensitivity of drug-resistant DLBCL to chidamide. Collectively, these findings provided valuable insights into the global impact of chidamide on DLBCL and highlight the potential of targeting HDACs as a therapeutic strategy for DLBCL. Identifying BCL6 as a biomarker for predicting the response to chidamide and the combination therapy with BCL6 inhibition has the potential to lead to more personalized and effective treatments for DLBCL patients.

In this study, we evaluated the efficacy and safety of a triplet regimen consisting of the histone deacetylase inhibitor chidamide, decitabine and anti-PD-1 camrelizumab (CDP) in 52 patients with relapsed/refractory cHL who had previously received DP therapy (NCT04233294)...The classical CD30+ HRS-like cells interacted with the abundant immunosuppressive IL21+CD4+ T helper cells, forming a positive feedback loop that supported their survival...CDP treatment promoted the activation of diverse tumor-reactive CD8+ T cells and suppressed the proliferation of IL21+CD4+ T cells by inhibiting STAT1/3 signaling, thereby alleviating their immunosuppressive effects. These findings provide insights into the cHL microenvironment that contributes to anti-PD-1 resistance and highlight the therapeutic effectiveness of dual epi-immunotherapy in overcoming immunotherapy resistance.
