Awards & highlights


This trial is testing whether adding vancomycin to SBRT increases the effectiveness of SBRT by measuring the Th1 immune response.

Who is the study for?
This trial is for adults who can consent and are set to receive SBRT for confirmed NSCLC. It's not open to those with chronic constipation, recent use of steroids or immunosuppressants, antibiotics, antifungals, antivirals, or chemotherapy. People with uncontrolled GI disorders, certain infections or a history of major GI surgery aren't eligible.Check my eligibility
What is being tested?
The study tests if adding vancomycin (an antibiotic) to SBRT boosts the Th1 immune response in early-stage non-small cell lung cancer patients by measuring specific immune signals like IFN gamma after treatment.See study design
What are the potential side effects?
Potential side effects may include typical reactions to antibiotics such as stomach upset and diarrhea. SBRT might cause localized pain, skin changes at the radiation site, fatigue and rarely more serious complications.
