New radiation technique aims to shield airways and preserve lung function
NCT ID NCT07679607
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This trial compares standard radiation therapy with a new method that specifically avoids damaging small airways in the lungs. The goal is to see if this airway-sparing approach helps patients with stage III non-small cell lung cancer retain better breathing function after treatment. About 70 participants will receive either standard or airway-sparing radiation, and their lung function will be measured at 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- airway-sparing radiation therapy (INSPIRE RT)
- What this could lead to
- If successful, this approach could help lung cancer patients preserve more lung function and improve quality of life after radiation therapy.
- What could go wrong
- This is a Phase 2 trial with 70 participants, so results are preliminary. The new planning method may not significantly improve breathing or could increase other side effects.

Inclusion Criteria: * Step 1- Inclusion Criteria 1. Adult (≥18 years) patients (both sexes) with histologically diagnosed Stage III NSCLC per AJCC ver 9 2. Patients to be treated with definitive external beam photon radiotherapy with or without systemic therapy (e.g., chemothrapy, immunotherapy). 3. No restrictions on number radiotherapy fractions, or location/number of lesions 4. ECOG performance status ≤ 3 5. Ability to hold breath for ≥ 15 seconds 6. Patient has signed informed consent document and agreed to study procedures Step 2- Inclusion Criteria 1. Patient has completed 4DCT and BHCT with subsequent plans created and Radiation Oncologist has determined that patient would benefit from INSPIRE RT. Exclusion Criteria: * Step 1- Exclusion Criteria 1. Prior lung cancer-directed radiotherapy 2. Recent (\< 12 mo) or planned lung surgery (which would confound pre- and post-RT lung function measures) 3. Patients with metal implants or metal stents in the thoracic region 4. Known severe chronic obstructive pulmonary disease or interstitial lung disease 5. Women who are pregnant or trying to get pregnant Step 2- Exclusion Criteria 1\. Patient found to not benefit from INSPIRE RT after comparison of treatment plans.
