About

In this study circulating tumor DNA (ctDNA) blood testing is used to detect the residual blood cancer. If residual cancer using this blood test is detected there may be at higher risk of having the cancer return. The study is going to test whether or not the number of circulating cancer cells detected in the blood can be reduced by administration durvalumab after the standard treatment if you are tested positive for the residual cancer.

Full description

Primary Objective:

The primary objective of this study is to measure the change in ctDNA from trial enrollment to after 2 cycles of adjuvant durvalumab in subjects with stage I to III NSCLC who had positive ctDNA following definitive treatment with surgery or radiation and completion of adjuvant standard of care chemotherapy. Secondary Objectives

1. To compare disease free survival (DFS)
2. To compare overall survival (OS)
3. To evaluate the frequency and severity of toxicity
4. To evaluate the severity of toxicity

Enrollment: 80 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion and exclusion criteria

17. Serum bilirubin ≤ 1.5 x upper limit of normal (ULN). This will not apply to subjects with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of evidence of hemolysis or hepatic pathology) who will be allowed in consultation with their physician.

18. AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional upper limit of normal (ULN)

19. Ability to understand and the willingness to sign the written IRB approved informed consent document.

21. Body weight >30kg

Exclusion Criteria

1. Involvement in the planning and/or conduct of the study

2. History of Grade 3 or higher pneumonitis from prior radiation; patients with grade 2 radiation pneumonitis may be considered for enrollment with permission from the Protocol Director or Co-Director.

3. History of another primary malignancy and currently undergoing active treatment Exception: May participate if receiving adjuvant endocrine therapy for breast or prostate cancer.

4. Expected to require ongoing chronic treatment with systemic immunosuppressive medication after enrollment.

   Exceptions: intranasal, inhaled, or topical corticosteroids or systemic corticosteroids at physiological doses, not to exceed 10 mg/day of prednisone equivalent

5. Any unresolved toxicity CTCAE > Grade 2 from prior therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria.

   • Subjects with Grade > 2 neuropathy will be evaluated on a case by case basis after consultation with the Protocol Director / Principal Investigator
   • Subjects with irreversible toxicity that is not reasonably expected to be exacerbated by treatment with durvalumab may be included (ie, hearing loss) with permission from the Protocol Director / Co-Director.

6. Active or prior documented autoimmune or inflammatory disorders which could limit the subjects ability to receive durvalumab on the study (including inflammatory bowel disease [eg, colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis; Graves' disease; rheumatoid arthritis; hypophysitis; uveitis; etc]). The following may be taken in to considerations as exceptions to this criterion:
