Safety and Pharmacokinetic Study of Escalating Multiple Doses of an Iron Chelator in Patients With Iron Overload

2014-08-27 03:17:00 | BioPortfolio

Summary

The purpose of this research study is to study the safety of increasing doses of FBS0701, and to see how quickly the study medication is absorbed and how quickly it disappears from the bloodstream. FBS0701 is a new, oral iron chelator - a medication taken by mouth that increases the body's elimination of iron. Iron chelators are used in patients who develop iron overload from their transfusions. Four increasing doses of FBS0701 will be tested during this study. The study will start with the lowest dose given to 4 patients (3 mg/kg/day. The next group of 4 patients will receive the next high dose (8mg/kg/day only after the results of the first 4 patients are examined and it is determined safe to continue. Participating patients will take the study medication for 7 days and be followed for 28 days after their last dose to determine if they have any reactions to the study medication - therefore a total of 35 days on study. Patients will need to give up to 17 blood samples over the screening period and first 15 days of the study (a total of about 9 tablespoons). Patients will not need to stay overnight in the clinic but will need to visit the clinic 10 times for screening and on-study visits over the 35 days. Patients currently taking an iron chelator will need to stop that treatment for up to 22 days (up to 5 days before they start the study and for 15 days during the study). The results of this study will be helpful in determining the safety of the drug and the best doses of FBS0701 to be used in the next study which will assess the effectiveness of this new iron chelator.

Medical and Biotech [MESH] Definitions

An excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. This may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (From Churchill's Illustrated Medical Dictionary, 1989)

Iron or iron compounds used in foods or as food. Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins hemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anemia.

A multifunctional iron-sulfur protein that is both an iron regulatory protein and cytoplasmic form of aconitate hydratase. It binds to iron regulatory elements found on mRNAs involved in iron metabolism and regulates their translation. Its rate of degradation is increased in the presence of IRON.

A multifunctional iron-sulfur protein that is both an iron regulatory protein and cytoplasmic form of aconitate hydratase. It binds to iron regulatory elements found on mRNAs involved in iron metabolism and regulates their translation. Its RNA binding ability and its aconitate hydrolase activity are dependent upon availability of IRON.

Anemia characterized by decreased or absent iron stores, low serum iron concentration, low transferrin saturation, and low hemoglobin concentration or hematocrit value. The erythrocytes are hypochromic and microcytic and the iron binding capacity is increased.
