Co-clinical Modeling of the Activity of the BET Inhibitor Mivebresib (ABBV-075) in AML.

Project description:Background/aimThe therapeutic potential of bromodomain and extra-terminal motif (BET) inhibitors in hematological cancers has been well established in preclinical and early-stage clinical trials, although as of yet, no BETtargeting agent has achieved approval. To add insight into potential response to mivebresib (ABBV-075), a broadspectrum BET inhibitor, co-clinical modeling of individual patient biopsies was conducted in the context of a Phase I trial in acute myeloid leukemia (AML).Materials and methodsCo-clinical modeling involves taking the patient's biopsy and implanting it in mice with limited passage so that it closely retains the original characteristics of the malignancy and allows comparisons of response between animal model and clinical data. Procedures were developed, initially with neonate NOD/Shi-scid-IL2rγnull (NOG) mice and then optimized with juvenile NOG-EXL as host mice, eventually resulting in a robust rate of engraftment (16 out of 26, 62%).ResultsResults from the co-clinical AML patient-derived xenograft (PDX) modeling (6 with >60% inhibition of bone marrow blasts) were consistent with the equivalent clinical data from patients receiving mivebresib in monotherapy, and in combination with venetoclax. The modeling system also demonstrated the activity of a novel BD2-selective BET inhibitor (ABBV-744) in the preclinical AML setting. Both agents were also highly effective in inhibiting blast counts in the spleen (10/10 and 5/6 models, respectively).ConclusionThese findings confirm the validity of the model system in the co-clinical setting, establish highly relevant in vivo models for the discovery of cancer therapy, and indicate the therapeutic value of BET inhibitors for AML and, potentially, myelofibrosis treatment.

MYC family amplification dictates sensitivity to BET bromodomain protein inhibitor Mivebresib (ABBV-075) in small-cell lung cancer.

Project description:Small-cell lung cancer (SCLC) accounts for nearly 15% of all lung cancers. Although patients respond to first-line therapy readily, rapid relapse is inevitable, with few treatment options in the second-line setting. Here, we describe SCLC cell lines harboring amplification of MYC and MYCN, but not MYCL1 nor non-amplified MYC cell lines, exhibit superior sensitivity to treatment with the pan-BET bromodomain protein inhibitor Mivebresib (ABBV-075). Silencing MYC and MYCN partially rescued SCLC cell lines harboring these respective amplifications from the anti-proliferative effects of mivebresib. Further characterization of genome-wide binding of MYC, MYCN, and MYCL1 uncovered unique enhancer and epigenetic preferences. Implications: Our study suggests that chromatin landscapes could establish cell states with unique gene expression programs, conveying sensitivity to epigenetic inhibitors such as mivebresib.

Silencing MYC and MYCN partially rescued SCLC cell lines harboring these respective amplifications from the anti-proliferative effects of mivebresib. Furthermore, the activity of mivebresib in SCLC cell lines occurs primarily through BRD2, rather than BRD4. Further characterization of genome-wide binding of MYC, MYCN, and MYCL1 uncovered unique enhancer and epigenetic preferences. Our study suggests that chromatin landscapes could establish cell states with unique gene expression programs, conveying sensitivity to epigenetic inhibitors such as mivebresib.

Genome-wide analysis of the effects of the novel mithramycin analogue DIG-MSK on human A2780 ovarian carcinoma cells

Project description:The effects of demycarosyl-3D-M-NM-2-D-digitoxosyl-mithramycin SK (DIG-MSK; EC-8042), a novel analogue of the antitumor antibiotic mithramycin A, on gene transcription were examined in human A2780 ovarian carcinoma cells. DIG-MSK down-regulated a different set of genes depending on the drug concentration. Moreover, several genes were significantly up-regulated. These results are rationalized in terms of DIG-MSK competition with Sp1 transcription factor for binding to consensus C/G-rich tracts encompassed in gene promoters. Human A2780 ovarian carcinoma cells were treated with either 8 nM or 80 nM DIG-MSK for 24 h, and RNA was extracted from treated cells as well as from untreated (control) cells.
