Trial Outcomes & Findings for A Study of 123I-CMICE-013 Radiopharmaceutical in Healthy Volunteers (NCT NCT01558362)

NCT ID: NCT01558362

Last Updated: 2025-03-26

Results Overview

SPECT imaging was performed immediately following 123I-CMICE-013 injection, after 90 min, 4 hours, 6 hours and 24 hours. Region of interest was manually drawn on planar images. The total number of counts in the full body region of interest of the initial images was taken to correspond to 100% of the injected dose. The uptake in the organ as a percentage to injected dose was calculated.

PRIMARY outcome

Timeframe: From enrollment to completion of imaging was 24 hours for each scan. Rest and stress scans were performed one week apart.

Population: Normal, healthy volunteers, with no pre-existing medical conditions were recruited. The volunteers were six (6) males and six (6) females and ranged from 18 to 42 years of age.

SPECT imaging was performed immediately following 123I-CMICE-013 injection, after 90 min, 4 hours, 6 hours and 24 hours. Region of interest was manually drawn on planar images. The total number of counts in the full body region of interest of the initial images was taken to correspond to 100% of the injected dose. The uptake in the organ as a percentage to injected dose was calculated.

Administration and analysis of alternative MPI radiotracer For SPECT imaging at rest, patients were injected with a 190 +/- MBq dose of 123I-CMICE-013 injected as a single bolus over 10-20 sec followed by a saline flush. Patients underwent SPECT imaging immediately following injection, after 90 in, 4 hours, 6 hours, and 24 hours. Regions of interest were manually drawn on planar images. The biodistribution of the 123I-CMICE-013 at rest was calculated.

Timeframe: From enrollment to completion of imaging was 24 hours for each scan. Rest and stress scans were performed one week apart.

Population: Normal, healthy volunteers, with no pre-existing medical conditions were recruited. The volunteers were six (6) males and ranged from 18 to 42 years of age.

The uptake of 123I-CMICE-013 in each organ from the primary outcomes were used to calculate the dose to each organ using the Olinda/EXM software package. doses for male patients were calculated using the adult male model. The results are reported as the mean and standard deviation of those measurements over all male participants for both the rest and stress SPECT imaging scans.
