Article Title: Distinct epitope engagement confers differential activity of linvoseltamab vs teclistamab across BCMA mutations ∗

doi: 10.1182/bloodadvances.2026020381

Figure Lengend Snippet: Effect of BCMA mutations on T-cell–mediated cytotoxicity against HEK293h/CD20 cells treated with linvoseltamab and teclistamab. HEK293 or OPM-2 myeloma cells were incubated for 3 days with isolated human T cells, with E:T of 12.5 (HEK293) and 5 (OPM-2). Target cell survival was determined by flow cytometry. Percentage survival was normalized to untreated cells. The OPM-2 cell line was used as a comparator because this is an MM cell line that endogenously expresses BCMA. E:T, effector-to-target ratio.

Figure Lengend Snippet: In vitro characterization of the optimized LXR agonist 7 . (a) Full‐length LXR reporter gene assay in HEK293T cells. N ≥ 3. (b) Quantification of LXR target genes in HepG2 cells. Both 2 and ( S )‐ 7 robustly induced expression of target genes involved in cholesterol metabolism (ABCA1, ABCG1) and DNL (FAS, SREBP1c). Data are the mean ± SEM of N = 4; ** p < 0.01, *** p < 0.001 (ANOVA with post hoc Bonferroni test against 0.1% DMSO or as indicated by the bars). Full agonist T0901317 ( 32 ) was tested for comparison. (c,d) Lipogenesis assay. Incubation of HepG2 cells with pan LXR full agonist T0901317 ( 32 ) for 72 h led to a substantial accumulation of lipids that were stained with Oil Red O. In comparison to 32 , both the parent compound 2 and ( S )‐ 7 displayed less lipogenic potential. Data are the mean ± SEM of N = 3; * p < 0.05, ** p < 0.01, *** p < 0.001 (one‐sided t ‐test against 0.1% DMSO). The images shown in (d) are representative details from the full images that can be found in Figure S3. (e) In a cytotoxicity assay, 2 and ( rac )‐ 7 did not influence the metabolic activity of HepG2 cells but induced cytotoxicity to HEK293T cells in the micromolar concentration region. While these concentrations are well above the EC 50 value of ( S )‐ 7 in the Gal4 reporter gene assay (red dashed line), compound 2 showed partially toxic effects at its EC 50 value (green dashed line). (f) Metabolic stability of 2 and ( rac )‐ 7 in rat liver microsomes. After 60 min, ( rac )‐ 7 was almost recovered completely, whereas approximately half of 2 had been metabolized. 7‐Ethoxycoumarine (7‐EC) served as internal standard. Data are the mean ± SEM of N = 3.
