This is a Phase 1 clinical trial evaluating the safety and tolerability of escalating doses of EC0225 in patients with refractory or metastatic tumors who have exhausted standard therapeutic options.
This is a Phase 1, dose escalation study of EC0225 administered by intravenous bolus (IV) during weeks 1 and 3 of a 4-week cycle to patients with refractory or metastatic cancer who have exhausted standard therapeutic options. EC0225 is a drug that is specifically designed to enter cells via a folate vitamin receptor. Experimental evidence shows that the target receptor is over-expressed in many human cancers. There are no previous human studies of EC0225; however, lab research (research in test tubes or animals) using EC0225 has shown activity against tumors in animals. This activity in animal models suggests that EC0225 may be useful as chemotherapy against human cancers. The primary objective of this study is to determine the safety and maximum tolerated dose of EC0225 given by intravenous bolus. The efficacy of treatment will also be measured.

Maternal folic acid (FA) protects against developmental toxicity from certain environmental chemicals.
The active metabolite of FOLIC ACID. Leucovorin is used principally as its calcium salt as an antidote to folic acid antagonists which block the conversion of folic acid to folinic acid.
Cell surface receptors that bind to and transport FOLIC ACID, 5-methyltetrahydrofolate, and a variety of folic acid derivatives. The receptors are essential for normal NEURAL TUBE development and transport folic acid via receptor-mediated endocytosis.
Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate hydrolase or synthesized from folic acid by the action of folate polyglutamate synthetase. Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active in bacterial growth assays.
A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. (Merck Manual, 16th ed)

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
