    Trial Purpose

    This study is being conducted to examine the safety and tolerability of SGN-LIV1A in
    patients with metastatic breast cancer, and to find the highest dose of the drug that can be
    given without unacceptable side effects. Other goals of the trial are to find out if
    SGN-LIV1A has any antitumor effects, to learn about the pharmacokinetics of SGN-LIV1A, and
    to explore the relationship between antigen expression and SGN-LIV1A effects.
