Summary

This trial is testing a new cancer treatment (durvalumab with SoC SBRT) against the current best treatment (placebo with SoC SBRT) for early stage non-small cell lung cancer.

Who is the study for?
This trial is for adults over 18 with early-stage, unresected non-small cell lung cancer without lymph node involvement. Participants must weigh more than 30 kg and have good organ function. Those with certain EGFR mutations can join an additional cohort. Contraception is required during the study.
What is being tested?
The trial tests if durvalumab combined with standard-of-care stereotactic body radiation therapy (SBRT) improves outcomes compared to placebo plus SBRT in one group, while another group receives osimertinib following SBRT if they have specific EGFR mutations.
What are the potential side effects?
Durvalumab may cause immune-related side effects like inflammation of organs, fatigue, and infusion reactions. Osimertinib could lead to diarrhea, rash, dry skin, nail changes, mouth sores and might affect heart rhythm or liver enzymes.
