This research aims to incorporate ctDNA analysis into clinical practice to individualize therapy in patients with stage III NSCLC by moving to a treatment-by-marker based approach (as opposed to treatment based on clinical or radiographic evidence of disease).
There is a critical need to identify MRD to determine which patients benefit from checkpoint inhibitor therapy and to optimize and personalize the duration of consolidation Durvalumab. The long-term goal is to incorporate ctDNA analysis into clinical practice to individualize therapy in patients with stage III NSCLC by moving to a treatment-by-marker based approach (as opposed to treatment based on clinical or radiographic evidence of disease). This approach may spare a subset of patients from treatment with unnecessarily excessive cycles of consolidation immunotherapy if they are already cured with CRT alone and individualize the duration of consolidation immunotherapy in patients not cured with CRT. The study team also seek to identify early in the treatment course, patients who are destined not to be cured with consolidation immunotherapy so that alternative strategies can be tested when tumor burden is low.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Consolidation to Durvalumab | Experimental | All subjects will receive consolidation Durvalumab approximately every 4 weeks. The first mandatory ctDNA test will be done at screening for the bespoke ctDNA profiling. The next mandatory ctDNA test will be completed prior to the 5th cycle of consolidation Durvalumab. If it's negative and the subsequent test 4 weeks later prior to cycle 6 is negative, then Durvalumab will be stopped otherwise subject will continue consolidation durvalumab until 2 negative ctDNA analyses performed approximately 4 weeks apart or up to 1 year of consolidation per standard medical practice is complete. |

| Signatera ctDNA test | Diagnostic Test | The first mandatory ctDNA test will be done at screening for the bespoke ctDNA profiling. The next mandatory ctDNA test will be completed prior to the 5th cycle of consolidation Durvalumab. ctDNA testing will be repeated approximately every 4 weeks until two consecutive negative analyses occur. ctDNA testing will be otherwise discontinued after progressive disease or after up to 1 year of consolidation treatment per standard medical practice is considered complete, whichever occurs first. |
