| In vivo | The antitumor effect of murine/human chimeric CD138-specific monoclonal antibody nBT062 conjugated with highly cytotoxic maytansinoid derivatives against multiple myeloma (MM) cells were investigated in vitro and in vivo. The in vivo activity of BT062SPDB-DM4, BT062-SMCC-DM1, and BT062-SPP-DM was examined in murine MM cell xenograft model of human and severe combined immunodeficient (SCID) mice bearing implant bone chips injected with human MM cells (SCID-hu model). The in vivo efficacy of nBT062-SPDB-DM4, nBT062-SMCC-DM1, and nBT062-SPP-DM1 was next evaluated in SCID mice bearing established CD138-positive MOLP-8 human MM cells. A single i.v. administration of the immunoconjugates caused significant dose-dependent tumor growth inhibition and tumor regression at concentrations that were well tolerated, evidenced by stable body weight. nBT062SPDB-DM4 was the most active conjugate tested in this model (Fig. 6A ). In addition, weekly dosing of the nBT062-SMCC-DM1 (six doses of 13.8 μg/kg) completely blocked tumor growth during the dosing period (Supplementary Fig. S6A). In summary, nBT062-SMCC-DM1, nBT062-SPDB-DM4, and nBT062-SPP-DM1 have in vitro and in vivo antitumor activity against CD138positive MM cells and can overcome the protective effects of cytokines and BMSCs Clin Cancer Res. 2009 Jun 15;15(12):4028-37. https://pubmed.ncbi.nlm.nih.gov/19509164/ | | Description | DM1-SMCC is a drug-linker conjugate composed of a potent microtubule-disrupting agent DM1 and a linker SMCC. | | Uses | SMCC-DM1 is a mertansine drug (DM1) with a reactive linker SMCC to make antibody drug conjugate. DM1 (mertansine), a thiol-containing maytansinoid, is a potent microtubule-disrupting agent. | | in vitro | In particular, the metabolic fate in cells of huC242-maytansinoid conjugates containing either a disulfide linker (huC242-SPDB-DM4) or a thioether linker (huC242-SMCC-DM1) was examined. The disulfide-linked antibody-maytansinoid conjugate, huC242-SPDBDM4, and the thioether-linked conjugate, huC242-SMCC-DM1, were first assayed for their cytotoxic potency against antigen-positive COLO 205 cells and antigen-negative Namalwa cells (both sensitive to maytansine with IC50 values of ～30 to 60 pmol/L for both cell lines) using an 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)–based assay. The conjugates displayed similar potencies with IC50 values of 40 pmol/L against COLO 205 cells and 20 to 80 nmol/L against Namalwa cells upon a 4-day exposure of the cells to the conjugates ( Fig. 1A ). To examine the fate of the maytansinoid drug upon incubation of target cells with an antibody-maytansinoid conjugate, conjugates with maytansinoids were prepared that were 3H-labeled at the C-20 methoxy group (see Fig. 5). Radiolabeled maytansinoid conjugates, huC242-SPDB-[3H]DM4 (250 mCi/mmol) and huC242-SMCC-[3H]DM1 (214 mCi/mmol), exhibit in vitro cytotoxicities similar to nonradiolabeled conjugate samples (data not shown). The two major metabolites, S-methyl-DM4 and lysine-Nε-SMCC-DM1, were synthesized and tested for their in vitro cytotoxicity against COLO 205 cells and Namalwa cells. Lysine-Nε-SMCC-DM1 was ～105-fold less potent against both cell lines with an IC50 value of 0.1 μmol/L (data not shown). Accumulation of the lysine-Nε-SMCC-DM1 metabolite from the noncleavable conjugate is coincident with the observed formation of the potent S-methyl-DM4, DM4, and lysine-Nε-SPDB-DM4 from the cleavable conjugate. This suggests that the lysineNε-SMCC-DM1 metabolite is as potent as the metabolites from the cleavable conjugate when delivered intracellularly and that all of the maytansinoid metabolites are active when produced in the cell.
