Personalized Escalation of Consolidation Treatment Following Chemoradiotherapy and Immunotherapy in Stage III NSCLC
Personalized Escalation of Consolidation Treatment Following Chemoradiotherapy and Immunotherapy in Stage III NSCLC
The purpose of this study is to test whether or not number of circulating cancer cells detected in the blood can be decreased the by combining the standard treatment (durvalumab) with Tremelimumab and additional chemotherapy
Primary objective is to measure the change in the levels of circulating tumor DNA (ctDNA) in Cohort 1 (MRD+) due to the addition of Tremelimumab and platinum doublet chemotherapy in subjects with stage III unresectable disease with positive DNA treated with consolidation chemotherapy and immunotherapy.
Secondary Objectives:
To determine the proportion of subjects in Cohort 1 MRD+ for whom ctDNA becomes undetectable after adding chemotherapy and tremelimumab to consolidation durvalumab
To describe compare overall survival (OS) of subjects with baseline detectable ctDNA (Cohort 1 MRD+) vs baseline undetectable ctDNA (Cohort 2 MRD ) ·To compare progression free survival (PFS) between subjects with baseline detectable (Cohort 1 MRD+) vs baseline undetectable ctDNA (Cohort 2 MRD )
Inclusion Criteria:
Histologically- or cytologically-documented NSCLC presenting with locally-advanced, unresectable stage III disease (Version 8 of AJCC Staging Manual) or NSCLC with locoregional recurrence after previous definitive treatment.
For stage III or recurrent disease, must have completed platinum-based chemotherapy and radiation therapy to all known tumor sites (60 Gy +/- 10%). Must not have known progression of disease.
Must be receiving consolidation durvalumab following completion of radiation and chemotherapy, and less than 32 weeks has elapsed from their first dose of durvalumab. (Patients may sign consent for study before start of durvalumab, but confirm eligibility and enroll only after first dose of durvalumab is received).
Able to potentially receive further consolidation chemotherapy plus durvalumab and tremelimumab, but not be currently intended to receive additional systemic consolidation chemotherapy apart from this durvalumab.
Pre-treatment tumor tissue or tumor DNA sample is believed to be available for analysis

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) (SGOT)/Alanine Aminotransferase (ALT) (SGPT) ≤ 2.5 x institutional upper limit of normal (ULN) unless liver metastases are present, in which case it must be ≤ 5 x ULN
Ability to understand and the willingness to sign the written IRB approved informed consent document.
Exclusion Criteria:
Involvement in the planning and/or conduct of the study
2. Previous enrollment or randomization in the present study
3. Received Investigational product as part of another clinical study
4. Mixed small cell and non small cell lung cancer histology
5. History of another primary malignancy and currently undergoing active treatment.
Exception: May participate if receiving adjuvant endocrine therapy for breast or prostate cancer.
6. Current or prior use of immunosuppressive medication within 14 days before enrollment, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. Systemic steroid administration required to manage toxicities arising from radiation therapy delivered as part of the chemoradiation therapy for locally advanced NSCLC is allowed.
7. Any unresolved toxicity CTCAE > Grade 2 from the prior chemoradiation 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) only after consultation with the Protocol Director / Principal Investigator.
8. Any prior Grade ≥ 3 immune related adverse event (irAE) while receiving any previous immunotherapy agent, or any unresolved irAE > Grade 1) that may limit subject from continuing durvalumab during the study
9. Recent major surgery within 4 weeks prior to entry into the study (excluding the placement of vascular access) that would prevent administration of study drug.
10. Active or prior documented autoimmune or inflammatory disorders which is likely to limit the subjects ability to continue 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]). Those with history of autoimmune or inflammatory disorders who are currently tolerating durvalumab may be eligible to participate with approval from the PI. The following are also exceptions to this criterion:
Vitiligo or alopecia
Hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement
Chronic skin condition not requiring systemic therapy
Celiac disease controlled by diet alone
11. History of primary immunodeficiency
12. History of organ transplant requiring therapeutic immunosuppression
13. History of hypersensitivity to carboplatin, pemetrexed, paclitaxel, or nab-paclitaxel that is likely to prevent re-administration of these agents
14. Active infection including but not limited to:
Grade 3 or higher clinically significant infection
Active 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
Active known Hepatitis C (HCV). EXCEPTION: Subjects positive for HCV antibody are eligible only if polymerase chain reaction is negative for HCV RNA
Active known tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice).
Active known HIV infection
15. Receipt of live attenuated vaccine within 30 days prior to the first dose of concurrent chemotherapy and durvalumab. Note: Subjects, if enrolled, should not receive live vaccine through 30 days after the last dose of chemotherapy concurrent with durvalumab.

Ongoing or active infection
Symptomatic congestive heart failure

Unstable angina pectoris
Cardiac arrhythmia
