A Study of 123I-CMICE-013 Radiopharmaceutical in Healthy Volunteers (CMICE)
|Study Design:||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
|Official Title:||A Phase 1 Study of Safety, Tolerance, Pharmacokinetics and Nuclear Medicine Imaging of 123I-CMICE-013 Administered Intravenously in Healthy Adult Volunteers|
- Biodistribution [ Time Frame: 0 to 24 hours post injection ]
Quantitative in vivo biodistribution will be determined through whole-body planar imaging immediately and at 90 mins, 4 hrs, 6 hrs and 24 hrs post injection. Venous blood samples of 10 ml volume each will be taken at nominal times of 5, 10, 15, 30, 60, 90 and 180 minutes post administration and at 6 and 24 hours and activity measured. Urine and faeces as voided up to 24 hrs post administration will be assayed.
Internal radiation dose, Effective Dose Equivalent (ICRP 30), Effective Dose (ICRP 60) and organ residence times will be calculated.
- Safety/Tolerability [ Time Frame: 0 to 7 days post injection ]Adverse events and Serious Adverse Events will be recorded and reported.

Administration and analysis of alternative MPI radiotracer
2 intravenous doses of drug will be given one week apart. Doses will be equivalent to 1 rest dose and 1 stress dose. Serial nuclear imaging will follow dose injections.
Single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) is an established, cost effective tool for the risk stratification and management of patients suspected or known to have coronary artery disease (CAD)Myocardial perfusion imaging is significantly affected by interruptions in the supply of 99mMo, the parent isotope of 99mTc used for the majority of MPI. An alternative radiotracer, I123-CMICE-013,developed at the Canadian Molecular Imaging Center of Excellence (C-MICE) at the University of Ottawa Heart Institute, has completed pre-clinical trial testing and is ready for Phase 1 human trials.
This Phase I study will be a single centre, open label study. Subjects will receive 2 doses of study drug. One rest dose and one stress dose will be administered on separate days, one week apart. Subjects will undergo a standard clinical exercise stress protocol for the stress dose. Gamma camera imaging following each administration will be done over 2 days.
Biodistribution, pharmacokinetics, dosimetry and safety variables will be analyzed.
