Detailed Description:



  • Evaluation of lung nodules (target and non-target lesions) detected during annual low-dose (ld) computed tomography (CT) scans and measured for three years after study completion in subjects enrolled in a randomized, phase IIb, placebo-controlled trial with inhaled budesonide (both person-specific and lesion-specific analyses will be performed).


  • Lung cancer detection rate in the two arms.
  • Appearance of new nodules in the two arms.

OUTLINE: Low-dose CT scans are analyzed retrospectively for the natural progression of undetermined lung nodules. Nodule dimension will be evaluated according to maximum diameter and volume, when feasible. Volume measurements are performed using an automatic and semi-automatic computer-aided diagnosis (CAD) system. Lesion-specific and person-specific analysis are performed by measure of average change in size of the target lesions or number of lesions.

Sampling Method:   Non-Probability Sample
Study Population
Participants previously enrolled in two trials: (1) a large scale COSMOS trial and (2) a subset of the COSMOS trial (MDA05-5-01 Budesonide study and treated for one year). Only participants enrolled in both trials will be included.


  • Annual Computed Tomography (CT) scans obtained from participants with undetermined lung nodules detected by low-dose CT enrolled in both of the following trials:

    • A large-scale COSMOS screening trial

      • Three annual CT scans obtained as part of the COSMOS trial after budesonide study treatment completion
    • The MDA05-5-01, a subset of COSMOS trial participants, a randomized phase II trial of inhaled budesonide twice daily versus placebo

      • Two CT scans performed as part of the budesonide protocol (MDA05-5-01)
  • Only CT scans from participants enrolled in both trials will be used
