Definitions

  • the invention relates to an antibody, known as LM-1 and a target, known as LM-1 Target or Antigen.
  • LM-1 is an IgM and binds to different types of neoplasia, cancer, tumor and metastasis.
  • LM-1 inhibits growth of various types of cancer cells and stimulates or induces apoptosis of various types of cancer cells.
  • LM-1 also reduces formation or establishment of metastases at one or more sites arising from a primary neoplasia, tumor or cancer, or growth or proliferation of a metastasis that has formed or been established at one or more other sites.
  • Metastatic disease at sites peripheral to the primary cancer potentially contribute to cancer progression and relapse. Consequently, inhibition of establishment or formation of metastasis, or reduction or decrease of metastasis growth, proliferation of or progression metastatic tumors that have been established is likely to reduce or inhibit cancer progression and relapse.
  • the invention addresses this need and provides related benefits.
