Comparison of Diagnostic Rest/Stress SPECT Results for Patients With Myocardial Ischemia and Infarction Using Myoview in Both Single and Dual Isotope Acquisition Approaches

Phase 4

Completed

• Conditions: Coronary Artery Disease
• Interventions: Drug: Technetium Tc99m Tetrofosmin injections; Drug: Thallous Chloride T1-201

• Registration Number: NCT00381316
• Lead Sponsor: GE Healthcare

Brief Summary

The study is designed to determine whether a dual isotope protocol is equivalent to a single isotope in the diagnosis of myocardial ischemia and infarction using MYOVIEW SPECT imaging.

Inclusion Criteria

1. The subject is 18 years old or older.
2. Male subjects or non-lactating female subjects, who are either surgically sterile (has had a documented bilateral oophorectomy and/or documented hysterectomy), postmenopausal (cessation of menses for more than 1 year), or for women of childbearing potential, the results of a serum or urine human chorionic gonadotropin pregnancy test, performed at screening within 24 hours before dosing (with the result known before investigational medicinal product administration) must be negative.
3. The subject is able and willing to comply with study procedures (i.e., 1 SPECT imaging at Stress, 2 SPECT imagings at Rest) and signed and dated informed consent is obtained.
4. The subject is suspected of or known of having CAD based on the subject's clinical signs, symptoms, or examinations .
5. The subject is referred for Rest/Stress (exercise or pharmacological) MPS-SPECT for known or suspected CAD (as clinically required).

Exclusion Criteria

1. The subject was previously included in this study.
2. The subject received an IMP within 30 days before or is scheduled to receive one during or in the next 30 days after IMP administration.
3. The subject has known allergies to any product used in this study or its constituents, including subjects who are not able to exercise and have contraindications to Adenosine (e.g., Asthmatics).
4. The subject presents any clinically active, serious, life-threatening disease, with a life expectancy of less than 1 month.
5. The subject has no contraindications to any of the study procedures (e.g. physical exercise) or the involved drugs (Myoview, Thallium-201, Adenosine or Dipyridamole) such as e.g. 2nd or 3rd degree AV-block, SS syndrome, bradycardia, bronchoconstrictive or bronchospastic lung disease.
