4、s on the anaplastic large cell lymphoma line L-82, butdelivered the same cytotoxic payload (monomethyl auristatin E, MMAE), and the intracellular concentration ofreleased MMAE correlated with in vitro ADC-mediated cytotoxicity independent of target expression ordrug:antibody ratios. LC-MS is used to

5、 measure the concentration of MMAE in a parallel cohort of L-82tumors with an identical treatment regimen. Although tumor volume is not different among treatment groups 3days after dose, the intratumoral MMAE measurement reveals two patterns. First, intratumoral MMAEconcentration increases proportio

6、nally to the ADC dose, which correspondes to stronger antitumor activity.Second, the intratumoral MMAE concentration obtained from treatment with both cOKT9-vcMMAE andcAC10-vcMMAE is similar at each dose, consistent with the observation that tumor responded similarly tothese two ADCs 1.體內(nèi)研究 Intratum

7、oral MMAE concentrations consistently correlates with the extent of tumor growth inhibition in tumorxenograft models. IHC analysis reveals that nonbinding control-treated tumors consist of both CD30+ andCD30-cells, presumably because they do not kill either CD30+ or CD30- Karpas 299 cells. Only CD30

8、- cellsare found in cAC10-vcMMAF-treated tumors, illustrating that cAC10-vcMMAF eliminates most CD30+ cells.Interestingly, the two tumors that relapses from cAC10-vcMMAE treatment are also found to be CD30- by theend of study, indicating a small fraction of CD30- cells might have escaped from bystan

The homogenates are centrifuged at 10,000 rpm to precipitate proteinand protein-bound payloads. The supernatant is then subjected to solid phase extraction, and signals ofMMAE and M
