3 Clinical Trials for Various Conditions
This study is aimed at describing the degree of benefit, if any, and the adverse effects, if any, from receiving 5 or more treatment sessions of Gadolinium Deposition Disease using two-day chelation treatment with the chelating agents Calcium Diethylenetriamine pentaacetate (Ca-DTPA) and Zinc Diethylenetriamine pentaacetate (Zn-DTPA).
Purpose: There are two goals we have for this prospective single arm study; to see an increase in the amount of gadolinium in 24 hour urine collection following each infusion treatment with Calcium and Zinc DTPA, and to see a reduction or elimination of gadolinium deposition disease (GDD) symptoms. Participants: Twenty (20) patients who are suffering from gadolinium deposition disease (GDD) Procedures: Over a series of three (3) treatment time-points patients will be treated with IV Ca-DTPA on day one, and Zn-DTPA on day two.
The study aims at gathering additional data on the safety and effectiveness of using intravenous administration of the drugs Ca-DTPA/Zn-DTPA to remove the heavy metal gadolinium from the bodies of patients who have retained it and developed symptoms of Gadolinium Deposition Disease following an MRI in which a gadolinium-containing contrast agent was utilized. The outcome data will include measures of symptom relief after as many as six paired Calcium-DTPA/Zinc-DTPA chelation treatments. The study also aims at gathering additional data before and after DTPA treatment regarding levels of certain cytokines in the patients' blood that have been reported to be abnormally elevated in patients with retained gadolinium.
