Menin (menin-KMT2A interaction). [1][2]
In a homogeneous time-resolved fluorescence assay, the average IC50 of JNJ-75276617 against human menin was 0.1 ± 0.05 nM across 10 independent experiments. Against mouse menin, IC50 was 0.045 ± 0.002 nM. Against dog menin, IC50 was ≤0.066 ± 0.004 nM. [2] In a fluorescence polarization binding assay, the Ki values for JNJ-75276617 against wild-type menin, M327I mutant menin, and T349M mutant menin were 0.02 nM, 0.4 nM, and 3.8 nM, respectively.

| ln Vitro |
JNJ-75276617 decreased menin binding to target gene promoters (MEIS1, HOXA9, HOXA10) in KMT2A-r MOLM-14 and NPM1c OCI-AML3 cells at concentrations from 0.1 to 1.0 μM, with fold decreases ranging from 1.4- to 24.7-fold compared to DMSO control. [2]
JNJ-75276617 suppressed mRNA expression of menin-KMT2A target genes (MEIS1, JMJD1C, FLT3, MEF2C, PBX3) and increased differentiation markers (ITGAM/CD11b, MNDA) in KMT2A-r and NPM1c AML cell lines. [2] JNJ-75276617 showed antiproliferative activity in AML cell lines: MOLM-14 (IC50 <0.1 μM), MOLM-13 (IC50 <0.1 μM), MV4-11 (IC50 <0.1 μM), THP-1 (IC50 >15 μM), EOL-1 (IC50 = 0.116 μM), OCI-AML3 (IC50 = 0.045 μM), and in B-ALL RS4;11 (IC50 = 0.040 μM). Normal peripheral blood mononuclear cells were not impacted up to 10 μM for 7 days. [2] JNJ-75276617 induced apoptosis in MOLM-14, OCI-AML3, and RS4;11 cells in a dose-dependent manner after 7 days of treatment. [2] JNJ-75276617 induced expression of CD11b and CD14 differentiation markers in MOLM-14 and OCI-AML3 cells after 3 and 7 days. In KMT2A-AF9-transduced mouse bone marrow cells, 200 nM JNJ-75276617 for 10 days increased neutrophil-like morphology (28.9% ± 2.6% vs DMSO 10.65% ± 1.35%). [2] JNJ-75276617 demonstrated antiproliferative activity against 6 of 13 NPM1c primary AML patient samples at days 7 and 14, and induced CD11b expression. It also showed antiproliferative effects and dose-dependent apoptosis in a primary KMT2A-r B-ALL patient sample. [2] JNJ-75276617 showed synergistic antiproliferative effects with gilteritinib in MOLM-13 cells (p<0.001). [2] JNJ-75276617 combined with venetoclax or with venetoclax plus azacitidine showed synergistic antiproliferative effects in MOLM-13 cells. [2] JNJ-75276617 retained potent antiproliferative activity in MEN1M327I and MEN1T349M mutant MV4-11 cells (IC50 = 22.6 nM and 53.59 nM, respectively). [2] JNJ-75276617 treatment (0.3 μM for 4 days) upregulated HLA-A and HLA-DR mRNA and protein expression in primary AML samples, and this was CIITA-dependent. [1] JNJ-75276617 pretreatment (0.3 μM for 4 days) enhanced T-cell-mediated cytotoxicity in allogeneic and autologous settings in primary AML samples, particularly those with NPM1c and DNMT3A mutations. [1] |
| ln Vivo |
In subcutaneous MOLM-14 AML xenograft mice, oral JNJ-75276617 (as oxalate salt) at 30, 50, and 100 mg/kg daily for 5 weeks induced dose-dependent tumor regressions of 70%, 97%, and 99%, respectively (p<0.0001 each). At 50 and 100 mg/kg, 10/10 and 9/9 tumors failed to regrow after 3 months off treatment. [2]
In a KMT2A-AF6 AML PDX model (CBAM-68552), JNJ-75276617 treatment significantly increased lifespan by >89% across all dose levels (p<0.05), reduced human CD45+ leukemic cells, and increased differentiation markers (CD11b, CD13, CD14). [2] In NPM1c AML PDX models (LEXFAM-2734 and AM7577), JNJ-75276617 at 30, 50, or 100 mg/kg resulted in median survival >133 days and >147 days, respectively (vehicle: 74 days and 53.5 days), with significant increased lifespan (>66% to >169%, p<0.0001). [2] In a KMT2A-AF4 B-ALL PDX model (CBAB-62871), JNJ-75276617 at 30 and 100 mg/kg daily increased lifespan by >48% and >160%, respectively (p=0.002), and reduced leukemia burden in bone marrow. [2] In a disseminated MOLM-13 model, JNJ-75276617 (10 mg/kg) combined with azacitidine (2 mg/kg) and venetoclax (100 mg/kg) induced a 277% increased lifespan (p<0.0001), superior to the azacitidine+venetoclax regimen (53% ILS). [2] In a disseminated OCI-AML3 NPM1c model, JNJ-75276617 combinations with azacitidine and venetoclax yielded superior survival vs azacitidine+venetoclax, though efficacy was mostly driven by JNJ-75276617.

| Enzyme Assay |
A homogeneous time-resolved fluorescence (HTRF) assay was used to quantify the ability of JNJ-75276617 to displace a fluorescein isothiocyanate (FITC)-labeled menin-binding motif 1 peptide (derived from KMT2A) from binding to terbium-labeled human, dog, and mouse menin. The compound was incubated with menin and FITC-MBM1 peptide, and the TR-FRET signal was monitored using a plate reader. Inhibitor potency was reported at 300 or 420 minutes when equilibrium was reached. Percentage inhibition and potency were calculated using Prism software. [2]
A fluorescence polarization binding assay was performed to assess binding of JNJ-75276617 to wild-type, M327I mutant, and T349M mutant menin. Dose-dependent displacement of a KMT2A peptide was measured. [2] |
| Cell Assay |
For the menin-KMT2A inhibitor screen, cryopreserved mononuclear cells from AML patients were thawed, resuspended in medium with DNase I, MgSO4, and heparin, then cultured in liquid medium with G-CSF, TPO, and IL-3 (all 20 ng/mL) or co-cultured on MS5 stromal cells. Cells were treated with DMSO or 0.03, 0.30, and 3.00 μM JNJ-75276617 for 14 days, with fresh medium and inhibitor added at day 7. On days 7 and 14, cells were stained with CD45-PECy7 and CD117, and fluorescence was measured using a flow cytometer. [1]
For apoptosis detection, cells were stained with annexin V and live/dead dye after treatment with JNJ-75276617 for up to 7 days, then analyzed by flow cytometry. [2] For differentiation assessment, cells were stained with CD11b and CD14 antibodies and analyzed by flow cytometry. May-Grünwald Giemsa staining was used to assess morphological changes in KMT2A-AF9-transduced mouse bone marrow cells after 10 days of treatment with 200 nM JNJ-75276617. [2] For T-cell cytotoxicity assays, primary AML samples were pretreated with 0.3 μM JNJ-75276617 for 4 days, then washed and co-cultured with anti-CD3/CD28 activated T cells from healthy donors at different effector:target ratios for 3 days. Viable cell counts were determined by annexin-V and Zombie NIR staining. [1] For autologous T-cell cytotoxicity, CD45+ blast and CD3+ T-cell populations were sorted from NPM1c AML patient samples, and AML blasts were cultured with or without their own T cells at a fixed ratio in the presence or absence of 0.3 μM JNJ-75276617. [1] For chromatin immunoprecipitation (ChIP)-qPCR, cells were cross-linked, lysed, and sonicated. Menin antibody was used for immunoprecipitation, and binding to target gene promoters (MEIS1, HOXA9, HOXA10) was quantified. [2] For the Quantigene multiplex assay, cells were treated with JNJ-75276617 or DMSO for 48-72 hours, then lysed. Target-specific probes were mixed with lysates, and signals were measured on a FLEXMAP 3D system. Absolute IC50 values were calculated by dose-response modeling. [2] |
| Animal Protocol |
Female 6- to 8-week-old immunocompromised mice were used for xenograft studies. JNJ-75276617 (as oxalate salt) was orally dosed daily at various concentrations (10, 30, 50, 100 mg/kg) for up to 4 weeks. Venetoclax (100 mg/kg) was orally dosed daily. Azacitidine (2 mg/kg) was dosed by intraperitoneal injection daily for the first week only. All experiments were performed in accordance with institutional guidelines. [2]
In the subcutaneous MOLM-14 model, tumor volume was measured, and tumor regression was assessed. In disseminated models, survival was monitored, and leukemic burden was assessed by flow cytometry for human CD45+ cells in bone marrow. [2] |
