Durvalumab for the Treatment of Patients with Stage IA2-III Non-small Cell Lung Cancer who Have Minimal Residual Disease

Trial Status: Active

This phase II trial studies the effect of durvalumab in treating patients with stage IA2-III non-small cell lung cancer who have positive minimal residual disease (MRD). Durvalumab is a checkpoint inhibitor and also known as immunotherapy. One of the ways tumors avoid being killed by the immune system is by expressing a protein on its surface called PD-L1, which interacts with PD-1 on the immune cell, and stops the immune cell from doing its job of killing the tumor. One of the most promising therapies involves activating the immune system to target and kill the cancer cells. Many cancers hide from the immune system by activating "checkpoints" like PD-L1 that the immune system uses to identify cells as normal cells. The immunotherapy treatments inhibit these checkpoints, allowing the immune system to target and kill cancer cells. Durvalumab targets PD-L1 and blocks the interaction of PD-1 and PD-L1, and essentially activate your immune system to target and kill the cancer cells. For patients with early stage disease, the backbone of therapy is surgery or radiation. Despite this, rates of disease coming back (relapse) after treatment of early stage disease remain high. Giving durvalumab after standard treatment may reduce the number of circulating cancer cells detected in the blood in patients with non-small cell lung cancer.

  • 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
  • Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 x institutional upper limit of normal (ULN)
  • Ability to understand and the willingness to sign the written Institutional Review Board (IRB) approved informed consent document
  • Women of childbearing potential or their male partner must agree to use a highly effective method of contraception from enrollment until 8 months after final study therapy

Exclusion Criteria

  • Involvement in the planning and/or conduct of the study
  • Previous enrollment or randomization in the present study
  • 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
  • History of another primary malignancy and currently undergoing active treatment (ie, chemotherapy, hormonal therapy, biologics)
  • Current or prior use of immunosuppressive medication within 14 days before enrollment. Exceptions: intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid
  • Any unresolved toxicity Common Terminology Criteria for Adverse Events (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
  • Active or prior documented autoimmune or inflammatory disorders which could limit the subject's 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: * Vitiligo or alopecia * Hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement * Chronic skin condition not requiring systemic therapy * Those without active disease in the last 5 years may be included with permission from the Protocol Director / Co-Director * Celiac disease controlled by diet alone
  • History of primary immunodeficiency
  • History of organ transplant requiring therapeutic immunosuppression
  • Active infection including but not limited to: * Known Tuberculosis * Known Hepatitis B (known positive results for HBV surface antigen (HBsAg) within 2 months prior to enrollment). EXCEPTION: Subjects with a past or resolved HBV infection, defined as the presence of hepatitis B core antibody (anti HBc) and absence of HBsAg are eligible * Known Hepatitis C (HCV) EXCEPTION: Subjects positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV ribonucleic acid (RNA) * Known human immunodeficiency virus (HIV) infection
  • Receipt of live attenuated vaccine within 30 days prior to enrollment. Note: Subjects, if enrolled, should not receive live vaccine while receiving the investigational product (IP), and through 30 days after the last dose of IP
  • Uncontrolled intercurrent illness, including but not limited to: * Ongoing or active grade 3 or higher infection * Symptomatic congestive heart failure * Uncontrolled hypertension * Unstable angina pectoris * Cardiac arrhythmia * Interstitial lung disease * Serious chronic gastrointestinal conditions associated with diarrhea * Psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the subject to give written informed consent
  • Female subjects who are pregnant or breast feeding
  • Any other medical condition that, in the investigator’s opinion, makes the subject unsuitable for enrollment and study procedures

I. To measure the change between pre and post treatment values for circulating tumor deoxyribonucleic acid (ctDNA) levels in subjects with baseline positive MRD (Cohort 1 MRD positive [+]).


I. To determine the proportion of subjects in whom ctDNA becomes completely undetectable after durvalumab (Cohort 1 MRD+).

II. To describe overall survival (OS) of subjects with detectable and undetectable ctDNA at enrollment (Cohort 1 MRD+ and Cohort 2 MRD negative [-]).

III. To compare disease free survival (DFS) of subjects with detectable and undetectable ctDNA at enrollment (Cohort 1 MRD+ and Cohort 2 MRD-).

IV. To evaluate the frequency and severity of toxicity of adjuvant durvalumab (Cohort 1 MRD+) patients that received at least 1 dose of study treatment).


Patients undergo ctDNA testing. Patients are assigned to 1 of 2 cohorts.

COHORT I (MRD+): Within 2 weeks of MRD+ test result, patients with detectable ctDNA receive durvalumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 28 days for up to 2 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo ctDNA testing on day 1 of cycle 1 and after 2 cycles of durvalumab. Patients unable to complete 2 cycles of durvalumab treatment undergo ctDNA testing at 8 weeks. In the absence of disease progression or toxicity, patients continue to receive durvalumab IV over 60 minutes every 28 days for up to 10 additional cycles.

COHORT II (MRD-): Patients without detectable ctDNA undergo surveillance.

After completion of study treatment, patients are followed up every 3-12 months for up to 5 years.
