Can a phone app and a CT scan help smokers kick the habit?
NCT ID NCT07331519
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests different ways to help smokers quit, including a smartphone app, written materials, and low-dose CT scans to screen for lung cancer. Researchers will enroll 1,200 smokers aged 50-74 and compare how many people successfully quit in each group. The goal is to see if combining lung cancer screening with smoking-cessation support works better than either approach alone.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Smartphone application for smoking cessation, low-dose computed tomography, and written materials
- What this could lead to
- If successful, this could show that combining lung cancer screening with digital smoking-cessation tools helps more people quit smoking and catch cancer earlier.
- What could go wrong
- This is a behavioral and screening study, not a drug trial. Results depend on participant motivation, and the CT screening may find harmless nodules that lead to unnecessary worry or procedures.
