About this study

Official title: A Phase 1 Study of Safety, Tolerance, Pharmacokinetics and Nuclear Medicine Imaging of 123I-CMICE-013 Administered Intravenously in Healthy Adult Volunteers

The need exists for alternatives to 99mTc based perfusion radiotracers for cardiac patient management. An alternative radiotracer, I123-CMICE-013, has been developed at the Canadian Molecular Imaging Center of Excellence (C-MICE) at the University of Ottawa Heart Institute. Initial testing results in rats and pigs suggest that in addition to being a cyclotron-produced alternative to 99mTc tracers, I-123-CMICE-013 may be a superior tracer for measuring myocardial perfusion.This Phase 1 study will study the safety and tolerability, biodistribution, pharmacokinetics and radiation dosimetry, and distribution and localization of I123-CMICE-013in healthy adult volunteers.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Biodistribution of the 123I-CMICE-013 Within the Lungs

    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.

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

  2. Biodistribution of the 123I-CMICE-013 Within the Thyroid

    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.

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

  3. Biodistribution of the 123I-CMICE-013 Within the Heart Wall

    SPECT imaging was performed at rest and at stress with each SPECT scan performed one week apart. 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.

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

  4. Biodistribution of the 123I-CMICE-013 Within the Bladder

    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.

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

  5. Biodistribution of the 123I-CMICE-013 Within the Liver

    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.

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

Secondary outcomes (2)
  1. Total Effective Dose of 123I-CMICE-013 for Men

    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.

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

  2. Total Effective Dose of 123I-CMICE-013 for Women

    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 female model. The results are reported as the mean and standard deviation of those measurements over all female participants for both the rest and stress SPECT imaging scans.

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