This invention relates to the field of immune therapy of cancer, more specifically to immunoconjugates of a cytotoxic moiety with a targeting moiety, more specifically to immunoconjugates of antibodies or fragments or functional derivatives of antibodies coupled to a cytotoxic substance such as drugs, toxins or radioisotopes. It especially relates to the release of substances bound to a targeting moiety through the use of acid-cleavable linker molecules.
