AZD0466 in patients with advanced non-Hodgkin lymphoma: Efficacy and safety in an open-label phase 1 trial (AACR 2024) - P1/2 | "AZD0466 is a drug-dendrimer conjugate consisting of the dual Bcl-2/Bcl-xL inhibitor AZD4320 covalently conjugated to a pegylated poly-L-lysine dendrimer, which allows for gradual release by hydrolysis. The study was terminated due to similar findings in a concurrent trial (D8241C00001; NIMBLE). With an objective response observed at the 1200 mg dose level, further development of agents targeting Bcl-2/xL in NHL is warranted with efforts to reduce the cardiotoxicity profile."

BCL-XL inhibitors enhance the apoptotic efficacy of BRAF inhibitors in BRAFV600E colorectal cancer. (PubMed, Cell Death Dis) - "While the BRAFV600E inhibitor encorafenib in combination with the EGFR inhibitor cetuximab (Enc+Cet) was recently approved for this indication, overall survival is only increased by 3.6 months and objective responses are observed in only 20% of patients. Combining encorafenib with DT2216 significantly increased apoptosis induction in vitro, while combining encorafenib with AZD0466 was well tolerated in mice and further reduced growth of BRAFV600E CRC xenografts compared to either agent alone. Collectively, these findings demonstrate that combined BRAF and BCL-XL inhibition significantly enhances apoptosis in pre-clinical models of BRAFV600E CRC and is a combination regimen worthy of clinical investigation to improve outcomes for these patients."

Pre-Clinical Study on the Dual BCL2/BCL-XL Inhibitor AZD0466 for the Treatment of Chronic Lymphocytic Leukemia (ASH 2023) - "To evaluate if combination treatment of AZD0466 with BTK inhibitors would improve efficacy, we transplanted murine Eµ-TCL1 tumors into syngeneic recipient mice and randomized them for treatment with vehicle, ibrutinib (30mg/kg in drinking water), acalabrutinib (25mg/kg, p.o. QD), AZD0466 (70mg/kg, i.v., QW) and combination of AZD0466 with ibrutinib or acalabrutinib. Moreover, AZD4320 was highly efficacious in MAVER-1 and MINO cell line models where resistance to venetoclax mediated by BCL-XL upregulation was modelled by an in vitro dose escalation method. In summary, our pre-clinical study shows that the dual BCL2/BCL-XL inhibitor could represent an important treatment option for venetoclax resistance mediated by specific BCL2 mutations or BCL-XL upregulation and that its efficacy could be further improved upon combination treatment with BTKi."

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."
