Official title: Phase I Study of the Safety, Distribution, and Radiation Dosimetry of Ultratrace Iobenguane 123I-mIBG-Nanodosing: the Path to Higher Sensitivity and Lower Toxicity Radiopharmaceuticals

Status Completed

Clinical Trial Summary

The goal of this proposal is to produce and test high specific activity Ultratrace iobenguane I 123 in normal human volunteers.

Clinical Trial Description

The goal of this proposal is to produce and test high specific activity Ultratrace iobenguane I 123 in normal human volunteers. The low specific activity iobenguane I 123 has been shown to be useful for the detection and staging of neuroendocrine tumors in adults and children and imaging neuronal activity in the heart. The innovation in this proposal is through the use of patented solid phase technology to produce a proven diagnostic agent at extremely high specific activity to increase sensitivity and specificity and lower radiation exposure to normal organs without the pharmacologically active cold carrier compound. The FDA considers iobenguane labeled with two different isotopes of iodine [I-131 and I-123] as two distinct drugs requiring distinct regulatory applications.

To meet the required quality standards for the chemistry, manufacturing and controls component of an IND application, GMP quality polymer drug precursor is used to generate the Ultratrace diagnostic iodine-123 agent. Analytical methods were validated with the proposed final drug formulation to demonstrate the final drug does not interfere with tests used to define the identity, purity, and strength of the agent. The drug product was verified for apyrogenicity and sterility before human testing. The IND application was written and submitted to the FDA and the Duke Medical Center IRB. MIP produces clinical trial material, and will conduct human testing of the radioactive drug substance for safety and superiority compared to conventional iobenguane I 123 in normal healthy volunteers. ;
