Definitions

  • the present invention relates to compositions comprising apilimod and methods of using same in the treatment of colorectal cancer.
  • Colorectal cancer remains a serious health concern. Globally it is the third most common cancer, making up 10% of all cases. In 2012 there were 14 million new cases and 694,000 deaths from colorectal cancer. Five year survival rates in the United States are around 65%, highlighting the need for more effective therapies.
  • Treatments for colorectal cancer may include some combination of surgery, radiation therapy, chemotherapy, and targeted therapy. Cancers that are confined within the wall of the colon may be curable with surgery. But in many cases, it is not possible to completely eliminate or cure the cancer once it has metastasized. Depending upon where and how big the metastases are, treatment may involve chemotherapy, surgery, gene therapy, immunotherapy, radiation therapy, and combinations of these. There remains a need for more effective treatment options for colorectal cancer. The present invention addresses that need.
  • the present invention is based in part on the surprising discovery that apilimod is a highly cytotoxic agent in colorectal cancer cells, including colorectal cancer cells that are resistant to other therapies, and further in combination with certain chemotherapy agents.
  • the disclosure provides a composition for treating colorectal cancer in a subject in need thereof, the composition comprising a therapeutically effective amount of apilimod, or a pharmaceutically acceptable salt, solvate, clathrate, hydrate, polymorph, prodrug, analog or derivative thereof.

  • the SNX10 gene expression level is called as ‘high’ relative to the SNX10 gene expression level of a reference cell line. For example, an SNX10 gene expression level in a biopsy sample that is higher than that of COL0205 cells, may be considered “high” for purposes of indicating sensitivity to apilimod.
