Synergy between enzalutamide and selective Bcl-2 family inhibitors in metastatic castration-resistant prostate cancer (ESMO Asia 2025) - "While venetoclax (Bcl-2 inhibitor) combinations with enzalutamide have entered clinical evaluation, the relative benefit of inhibiting different Bcl-2 family members under identical experimental conditions has not been directly compared. DU145 mCRPC cells were treated for 48 h with enzalutamide (ENZA) alone or in combination with ABT-199 (Bcl-2 inhibitor), A-1331852 (Bcl-xL inhibitor), or AZD5991 (Mcl-1 inhibitor). In a direct comparison under uniform conditions, Mcl-1 inhibition with AZD5991 emerged as the most effective partner for ENZA in DU145 cells, followed by Bcl-xL inhibition, while Bcl-2 inhibition was less impactful. These findings support further evaluation of Mcl-1-targeting strategies as a means to overcome AR-independent resistance in mCRPC, while underscoring the need for cautious interpretation of large in-vitro dose-reduction estimates."

Proteasome inhibition as a potential therapeutic target in thymic cancer. (PubMed, Cell Death Dis) - "Carfilzomib synergized with BCL2 family protein inhibitors (navitoclax or AZD5991), suggesting that drug combinations could be used to reduce the dose of each drug to minimize toxicity. Notably, thymic carcinomas differed from squamous cell carcinomas in other organs by higher levels of β5i (PSMB8) and constitutive proteasome β5 (PSMB5). We hypothesize that TC (and probably many TH) are uniquely suited for treatment with proteasome inhibitors alone or in combination with selective BH3 mimetics."

CSF1R-CSF1 axis blockade with axatilimab effectively targets leukemia stem cells and monocytes in AML resistant to BH3 mimetics (ASH 2025) - "Background : The BCL2 inhibitor venetoclax (VEN), in combination with hypomethylating agents, ishighly effective in inducing remissions in AML...The effects on cytokine production, AML blasts, stem cells, andmonocytes were evaluated. MV4-11 cells with acquired resistance to BH3 mimetics targeting BCL2 or MCL1,peculiarly to VEN and VEN plus MCL-1 inhibitor AMG176, exhibited elevated levels of cytokinesincluding CSF1, TGF-1ß, IL-4, and IL-10 compared to parental cells... CSF1, TGF-1ß, IL-4, IL-10, and numerous other cytokines are increased in BH3mimetic resistant AML cell lines and patient samples. Inhibition of CSF1R targets ERK and AKTsignaling and significantly enhances the cytotoxic effects of BH3 mimetics against AML cells,stem/progenitor cells, and monocytes resistant to VEN. Furthermore, blockage of CSF1R-CSF1axis suppresses multiple cytokines in vitro and in vivo, and markedly improves the therapeuticefficacy of BH3 mimetics in a VEN/AZD5991/Decitabine..."

Epitranscriptomic signatures define prognosis and therapeutic vulnerabilities in large B-cell lymphoma (ASH 2025) - "The first-line treatment consists of a R-CHOP-like regimen,where 20-40% of patients are refractory to the treatment or will relapse (R/R)...The results showed asynergic effect between the anti-apoptotic protein inhibitors tested and YTHDC1i, particularly with at alow dose of venetoclax (0.01 µM, BCL-2 inhibitor), with a mean of 17% of viability of OCI-LY1 cells, incomparison to venetoclax alone (mean of 35% viability). Interestingly, when the MCL-1 inhibitor (0.1 µM,AZD-5991) was combined with YTHDC1i, we reached a mean of 8% of viability in comparison to MCL-1ialone (mean of 62%)... Our study reveals that specific epitranscriptomic modifications and the expression of theirregulatory enzymes are significantly associated with overall survival in patients with LBCL. Among these,i6A and its writer, TRIT1, correlate with a better prognosis, while m1G and m1A, along with theirassociated enzymes, predict poorer outcomes. Functional assays identified YTHDC1 as a..."

Identification of vulnerabilities for targeting BCL-2 family members in T-Cell Acute Lymphoblastic Leukemia (ASH 2023) - "Venetoclax is a selective BCL-2 inhibitor and is successfully used in CLL and AML, but heterogeneous sensitivity to venetoclax has been described in ALL and inhibitors of other BCL-2 family members including BCL-XL-selective A-1331852 and MCL-1 selective AZD5991 have been developed. Moreover, a dual inhibitor of the anti-apoptotic BCL-2 family members BCL-2 and BCL-XL (AZD4320) with its dendrimer conjugate (AZD0466) has recently shown anti-tumor activity in hematologic cancer models with manageable toxicity...Taken together, we found vulnerabilities of T-ALL to BCL-2 family inhibition, particularly to dual BCL-2/BCL-XL inhibition by AZD4320, and we demonstrated on-target activities. Using BH3-profiling, we identified BAD-priming as a marker of response for AZD4320 and MCL-1 dependence as a resistance mechanism that can be targeted by combination treatment, suggesting further clinical evaluation."

Targeting MCL-1 to Overcome Therapeutic Resistance and Improve Cancer Mortality. (PubMed, Health Sci Rep) - "The structural foundations for the design of MCL-1 inhibitors are revisited, the pharmacological profiles of the leading drugs (S63845, AZD5991, AMG 176) in advanced clinical development are summarized, and emerging strategies, such as combination therapies with inhibitors of anti-apoptotic proteins such as BCL-2, PROTAC strategies designed to degrade MCL-1, and reversible-binding chemotypes to maximize MCL-1 inhibition and minimize toxicity, are reviewed. The key to clinical success will be to carefully develop more intensive dosing regimens, rationally combine agents, and develop trial designs that prioritize the evaluation of new agents that maximize antitumor activity without the risk of off-target toxicities. Continued translational research and adaptive clinical trials are critical to fully realize the therapeutic potential of MCL-1 inhibition across various cancer contexts."

INHIBITION OF CSF1R-CSF1 AXIS WITH AXATILIMAB EFFECTIVELY TARGETS LEUKEMIA STEM CELLS AND MONOCYTES IN BH3 MIMETICS-RESISTANT AML (EHA 2025) - "Background: BCL2 inhibitor venetoclax (VEN)/hypomethylating agent regimen are highly effective in inducing remissions in AML. We demonstrate that inhibition of CSF1R enhances the cytotoxic activities of BH3 mimetics and is highly active in combination with both BH3 mimetics against AML cells and stem/progenitor cells resistant to VEN. Targeting CSF1R-CSF1 axis suppresses multiple cytokines in vitro and in vivo, and significantly enhances the therapeutic efficacy of BH3 mimetics in a VEN/AZD5991/Decitabine triple resistant PDX model."
