In Vitro | In vitro activity: When coupled to cAC10, MMAE shows selective cytotoxicity in CD30+ cells, and induces G2/M-phase growth arrest and cell death through the induction of apoptosis. [1] When coupled to anti-CD79b antibody, anti–CD79b-vcMMAE has very potent and broad activity across a large panel of NHL cell lines in vitro. [2] When coupled to anti-HER2 antibody, hertuzumab-vc-MMAE can also be effectively internalized and potently kill HER2 over-expressing tumor cells. Cell Assay: Cytotoxicity is measured using Alamar Blue dye reduction assay according to the manufacturer's directions. Briefly, a 40% solution (wt/vol) of Alamar Blue is freshly prepared in complete media just before cultures are added. Ninety-two hours after drug exposure, Alamar Blue solution is added to cells to constitute 10% culture volume. Cells are incubated for 4 hours, and dye reduction is measured on a Fusion HT fluorescent plate reader (Packard Instruments, Meriden, CT). Cell lines used: CD30+ Karpas 299 cells |

In Vivo | The Karpas 299 ALCL model, cAC10-vcMMAE (1 mg/kg, i.v.) induces complete, durable tumor regression, while free MMAE (0.36 mg/kg) doesn’t produce detectable antitumor activity. In mouse xenograft models of NHL, anti–CD79b-vcMMAE (7 mg/kg, p.o.) strikingly results in sustained complete tumor remission. |
Animal model | In vivo therapy tests were undertaken in athymic mice with subcutaneous L2987 human lung adenocarcinoma xenografts. MMAE conjugates were administered at 3 mg mAb component/kg/dose. All of the tested MMAE conjugates were highly efficacious, leading to long-term regressions of established tumors, whereas the nonbinding control conjugates had no effect on tumor growth. In addition, there were no apparent toxicities associated with conjugate treatment |
Formulation & Dosage | 6-8 week old female athymic nu/nu mice are injected subcutaneously into thighs with 5×106 HCT-116 or PANC-1 cells in a 1:1 Matrigel and PBS solution. Mice are treated with IR or intravenous (IV) injection of ACPP-cRGD-MMAE (6 nmoles/day, 18 nmoles total, i.v.), tumor tissue is harvested, formalin fixed and paraffin embedded followed by staining with indicated antibodies. The primary antibody is used at a 1:250 dilution and is visualized using DAB as a chromagen with the UltraMap system. |
