All subjects will receive a full physical examination at IND to determine study eligibility. Written informed consent will be obtained prior to any study procedures. The screening procedures will include: review of medical and psychiatric history, review of medications, physical examination including height and body weight, vital sign measurements, review of inclusion/exclusion criteria, clinical laboratory testing (serum chemistries, CBC, urinalysis, urinary drug screen), urine pregnancy test for females of childbearing potential and electrocardiogram in preparation for the imaging study.
Part A: Four healthy subjects will each receive one injection of 123-I INER. Serial whole body planar imaging in the anterior and posterior projection will be performed over the 8-9 hour period following injection of 5 mCi of 123-I INER and again at 18-24 hours following injection. Venous blood data will be acquired at each imaging time point. In addition a 24 hour urine collection will commence following radiotracer injection. Whole body and source organs uptake will be analyzed on anterior and posterior images for calculating the radiation absorbed doses to organs. Plasma and urine metabolites will be characterized and safety assessments obtained. Serial safety assessments will include vital signs, serum chemistries, CBC, urinalysis, and EKGs.
Part B: Six healthy subjects will each receive one injection of 123-I INER. Following bolus intravenous injection of 5 mCi of 123-I INER over 15 seconds, serial dynamic SPECT brain acquisitions will be obtained to evaluate the regional brain uptake and washout of activity. Venous blood measures will be obtained with each acquisition and characterization of 123-I INER and metabolites will be assessed. Safety assessments will include vital signs, serum chemistries, CBC, urinalysis, and EKGs.

Experimental: 123-I INER
To assess 123-I INER
Drug: 123-I INER
Serial whole body planar imaging in the anterior and posterior projection will be performed at 1 min, 30 min, 1 h, 2h, 3h, 4h, 5h, 6h, 7h, 8h, and 18-24h following injection of 5 mCi of 123-I INER. Venous blood data will be acquired at each imaging time point. In addition a 24 hour urine collection will commence following radiotracer injection and urine sampled in five collections every 4 hours collection for first sixteen hours (4 collections), then one collection from 16 to 24 h. Whole body and source organs uptake will be analyzed on anterior and posterior images for calculating the radiation absorbed doses to organs using the MIRD method as described previously (Seibyl, et al, 1993). Plasma and urine metabolites will be characterized and safety assessments obtained.
- Assess the biodistribution and metabolic rate of 123-I INER for determination of radiation absorbed dose estimates. [ Time Frame: 2 yrs ]
- Assess of regional brain uptake and washout and plasma metabolite analysis to determine the brain penetrance and regional distribution and washout counts following 123-I INER injection. [ Time Frame: 2 years ]
