Resumen
Fecha de inicio: 1 de agosto de 2002
Fecha en la que se inscribió al primer participante.The investigational new drug (FolateScan or Technetium Tc 99m EC20) is a folate-targeted diagnostic radiopharmaceutical designed to bind to the folate receptor. The folate receptor is a glycoprotein that is over-expressed in many types of cancer cells but it is only minimally distributed in normal tissues. Folate conjugates bind to the folate receptor with high affinity and are brought into the cell via endocytosis. In contrast, folic acid itself enters most normal cells via the reduced folate carrier, a pathway entirely inaccessible to folate conjugates. Therefore, these folate conjugates are specific to cancer cells. Endocyte's folate-targeted delivery system was applied towards the targeting of a diagnostic imaging agent (111In-DTPA-Folate) to ovarian cancer tumors. This proof-of-principle study was designed to demonstrate the ability of folate to target drugs to folate-receptor-positive (FR+) cancer tissue.
