Biodistribution and Safety of a Radiopharmaceutical in Healthy Subjects

NCT00316797 | Completed Phase 1 DMC

• 1 other identifier: H01_INER_001/002
• Study Type: interventional
• Target: 35
• Locations: 1 country
• Sites: 1

Brief Summary

The initial study of \[123I\] INER will be completed in two parts. Once Part A (Preliminary whole body biodistribution) is completed, Part B (Serial dynamic SPECT assessment 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) will commence. All study procedures will be conducted at the Institute for Neurodegenerative Disorders (IND) and Molecular NeuroImaging (MNI) in New Haven, CT. All subjects will undergo written informed consent and a screening evaluation including baseline clinical laboratory testing, and a baseline physical and neurological evaluation.

Outcome Measures

Primary Outcomes (1)

• Assess the biodistribution and metabolic rate of 123-I INER for determination of radiation absorbed dose estimates.

  2 yrs

Secondary Outcomes (1)

• 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.

  2 years

Study Arms (1)

123-I INER

EXPERIMENTAL

To assess 123-I INER

Drug: 123-I INER

Interventions

123-I INER DRUG

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.
