Developing epigenetic synergistic drug combinations with albendazole in paediatric acute myeloid leukaemia (ASH 2025) - "Similar anthelmintic agents, mebendazole (MBZ) and parbendazole (PBZ), have been reported to have effects on epigenetic regulators that alter C-MYB degradation (Walf-Vorderwülbecke et al...These epigenetic hits represent various target families such as HDAC inhibitors (vorinostat, panobinostat, and CUDC-101), BET inhibitors (OTX-015, PFI-1, and (-)-JQ), aurora kinase inhibitors (MK-8745 and JNJ-7706621), and DNA synthesis inhibitors (cytarabine)...HDAC inhibitors (vorinostat), BET inhibitors (OTX-015) and histone methyltransferase (MS023) were among the most represented epigenetic target families, indicating potential mechanism of action of the novel ABZ+epigenetic combination. The novel drug candidate ABZ was found to have remarkable anti-leukaemia efficacy in murine and human models of childhood AML in vitro and in vivo while having negligible effects in normal cells. Current work is focused on evaluating ABZ+epigenetic synergistic combinations that will be taken..."

Actionable Findings from an Unbiased Drug Screen for Novel Single Agent and Combination Therapies Against AML with Mecom Re-Arrangement (ASH 2023) - "This was consistent with previous reports that BET inhibitors (e.g., OTX015, mivebresib or ABBV-075 and JQ1) are effective against 3q26.2-r AML cell lines, patient-derived (PD) AML cells and PDX models...In follow-up experiments, XIAP/cIAPs inhibitors birinapant (10-1000 nM) or SM-164 (30-1000 nM), chosen based on the MIPE screen outcomes, induced significantly more dose-dependent apoptosis in 3q26.2-r versus the other AML cell lines...Treatment with the dual mTOR/PIK3CA inhibitor NVP-BGT226 (1-30 nM) or navitoclax or Bcl-xL-specific BH3 mimetic A-1155463 also exerted lethality and synergistically induced apoptosis with mivebresib in AML cells with inv3/t(3; 3)...Co-treatment with birinapant and tegavivint also synergistically induced apoptosis in 3q26.2-r AML cells...Additionally, compared to each drug or vehicle control, co-treatment with birinapant and the BETi OTX015 (30 mg/kg/day, by oral gavage) was more effective in reducing AML burden in the xenograft model...."

The histone modifier KANSL2 is an actionable biomarker in multiple myeloma. (PubMed, Mol Cancer Ther) - "High KANSL2 levels increased sensitivity to the histone deacetylase (HDAC) inhibitor panobinostat and bromodomain and extra-terminal motif (BET) inhibitor OTX-015 and their combination. Ex vivo drug response profiling in relapsed/refractory MM patient samples confirmed that high KANSL2 expression is associated with selective MM cell killing by HDAC and BET inhibitors. Collectively, these findings position KANSL2 as a mediator of chemotherapy resistance and actionable biomarker for response to drugs targeting its epigenetic program."

In a separate experiment on the same PDX model, treatment with TM (30 mg/kg/day) also induced significantly greater survival advantage than treatment with ruxolitinib (30 mg/kg/day) or OTX015 (30 mg/kg/day) by oral gavage. These findings clearly demonstrate preclinical efficacy of TM in advanced MPN-BP cellular models and create the rationale to further interrogate the efficacy of TM alone and in combinations with current, front-line therapies for advanced MPN with excess blasts."

Development and Efficacy of a Novel Bromodomain and Extraterminal Domain Degrader K-256 in MYC/BCL2-Related Lymphoma (ASH 2023) - "The GI50 of K-256 in SU-DHL4 and SU-DHL6 was 12.8 nM and 7.50 nM, respectively, and K-256 induced cell death at lower concentrations than existing drugs (vs. JQ1, OTX-015, and ABBV-075, p < 0.0001; vs. dBET6 and ARV-771, p < 0.01)...As expected, the combination of K-256 with venetoclax also demonstrated synergistic effects in PDX cells, similar to those observed in cell lines (CI of 0.515 to 0.762 for inhibiting cell proliferation; 0.085 to 0.995 for inducing apoptosis)... The novel BET degrader, K-256, bound to BET proteins at lower concentrations than existing BET inhibitors and degraders, strongly suppressing MYC expression, primarily via BRD4 degradation. Additionally, K-256 demonstrated superior therapeutic effects in MYC/BCL2-related PDX models both in vitro and in vivo, suggesting that this novel drug could be a promising therapeutic agent for MYC/BCL2-related lymphoma. Its translation to future clinical applications warrants further consideration."

The Resistance Mechanism to BET-Protac in Multiple Myeloma (ASH 2023) - "AR1 and AR2 cells showed decreased sensitivity to ARV-825, MZ-1, OTX-015, I-BET151, Daunorubicin and Epirubicin...Combined use of ABCB1 inhibitors (verapamil, cyclosporin A, Elacridar) or knockout of ABCB1 could significantly reduce the IC50 of drug-resistant cells, increase the apoptosis rate after ARV-771 treatment, and increase the degradation of BRD4 and the down-regulation of c-Myc... Our results showed that BET-PROTAC resistance in MM cells wasindependent of β-catenin activation. The up-regulation of ABCB1 expression was the key mechanism mediating the resistance of myeloma cells to BET-PROTAC. C1orf112, CCDC167 and CRIP2 might be associated with drug resistance in myeloma and could affect prognosis, and their mechanisms in myeloma need to be further investigated."

Identifying 'Druggable' Targets and Preclinically Overcoming Non-Genetic/Adaptive Resistance to Menin Inhibitors in AML with MLL1r or mtNPM1 (ASH 2024) - "These MITR cells exhibited cross-resistance to other MIs, including ziftomenib and DS1594b...Notably, in a luciferized MLL1r MITR AML PDX model, compared to treatment with each agent alone, co-treatment with FHD-286 and SNDX-5613 or OTX015 for 8-weeks yielded significantly superior survival of the NSG mice (p < 0.05). These findings demonstrate that co-treatment with FHD-286 overcomes in vitro and in vivo MI-resistance, while significantly improving in vivo efficacy of BETi in the cell-line xenograft and PDX models of MITR AML cells. They also show that combinations of epigenetically targeted agents may be effective in MI-sensitive or -resistant AML with MLL1r or mtNPM1."

In patients with sepsis, elevated BRD3 levels correlate with accelerated inflammation, increased disease severity, and a greater risk of in-hospital death. These findings establish BRD3 as a potential therapeutic target for managing infection-associated immune dysregulation."
