Title: A Multicenter Phase 3 Study Comparing the Diagnostic Accuracy of 99mTc EC DG SPECT/CT Versus 18F FDG PET/CT for Diagnosing and Staging Patients Who Have Clinical and Radiological (CT) Evidence Consistent With a Diagnosis of Lung Cancer1

Responsible Party: Cell>Point LLC

Description: For this non-randomized, open label, phase 3 study (ClinicalTrials.gov Identifier: NCT01394679), researchers are attempting to determine whether lung cancer diagnosis and staging using SPECT/CT 99mTC [technetium]-EC-DG [ethylenedicysteine-deoxyglucose] scanning is non-inferior to PET/CT 18F-FDG scanning.

Patients will undergo PET/CT imaging or SPECT/CT imaging. The primary outcomes are a comparison of the imaging techniques and non-inferiority of SPECT/CT; the secondary outcome is safety.
