  • Patent number: 8388960
    Abstract: Methods of killing or inhibiting tumors comprising of heterogeneous or mixed cell populations is described. The killing or inhibition of tumors is achieved by selectively targeting a unique ligand suspected of being expressed on a particular cell population to also kill a cell population lacking the unique ligand. These conjugates have therapeutic use as they are delivered to a specific cell population to kill these cells and the cytotoxic drug is released to kill non-targeted cells, thereby eliminating the tumor.

  • Publication number: 20080171856
    Abstract: The present invention discloses a method for targeting maytansinoids to a selected cell population, the method comprising contacting a cell population or tissue suspected of containing the selected cell population with a cell-binding agent maytansinoid conjugate, wherein one or more maytansinoids is covalently linked to the cell-binding agent via a non-cleavable linker and the cell-binding agent binds to cells of the selected cell population.
