Clinical Trial Summary

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

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.

Eligibility

Inclusion Criteria:

• normal healthy volunteers with written informed consent who understand and are willing to comply with protocol requirements

• at least 21 years of age

• if female, then not of childbearing potential as documented by history (e.g., tubal ligation or hysterectomy) or is post menopausal with a minimum 1 year without menses

• if female of childbearing potential, a negative serum beta HCG pregnancy test within 24 hours prior to receiving iobenguane I 123

• if female of childbearing potential, agrees to use an acceptable form of birth control, defined as abstinence or use of IUD, oral contraceptive, barrier and spermicide, or hormonal implant, throughout the study period

• No existing predisposition to administration of thyroid blocking potassium iodide

Exclusion Criteria:

• females who are nursing

• documented history of significant allergy that required medical intervention to shellfish, X-ray contrast media, iodine/iodides, or iobenguane

• administered a radioisotope within 5 effective half-lives of that radioisotope prior to study enrollment

• abnormal screening laboratory studies (serum creatinine, SPOT, SGPT, total bilirubin as defined by standard laboratory reference ranges)

• those who have received an investigational compound and/or medical device within 30 days of entering this study

• pre-existing medical condition or circumstances which would significantly decrease the chances of obtaining reliable data, achieving study objectives, or completing the study, (e.g. cancer, heart disease, or other medical conditions which potentially alter normal biodistribution)

• is determined by the investigator that the patient is clinically unsuitable for the study

• are taking medication which inhibits uptake of iobenguane I 123 within 2 weeks of enrollment, or tricyclic antidepressants or related drugs within 6 weeks of enrollment. Categories of medications include sympathomimetics, antihypertensives and cardiovascular agents, opioids, antipsychotics, tricyclic antidepressants, and medications as previously published

• have participated in a clinical trial with an investigational drug in the past 30 days.
