Brief Summary

This randomized clinical trial studies how well tremelimumab and durvalumab with or without radiation therapy works in treating patients with small cell lung cancer that has returned after a period of improvement. Monoclonal antibodies, such as tremelimumab and durvalumab, may limit the ability of tumor cells to grow and spread by enhancing immune function. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving tremelimumab and durvalumab together with radiation therapy may lead to improved clinical benefit.

Detailed Description

PRIMARY OBJECTIVE:

I. To assess the efficacy (progression free survival [PFS] and objective response rate [ORR]) of combined immune checkpoint inhibitor therapy as treatment for relapsed small-cell lung cancer (SCLC).

SECONDARY OBJECTIVES:

I. To assess the impact of antigen priming using radiation therapy (XRT) on the efficacy of immune checkpoint inhibitors.

II. To determine immune related objective response rate.

III. To estimate overall survival measured as time from randomization to death from any cause.

TERTIARY OBJECTIVES:

I. To characterize tumor infiltrating lymphocytes (TILs) and programmed cell death 1 ligand 1 (PD-L1)/programmed cell death 1 (PD1) expression in paired tumor biopsies at baseline, end of cycle 2 and at the time of progression.

II. To determine dynamic changes in cell free deoxyribonucleic acid (DNA) (cfDNA) and the immunophenotype of peripheral blood repertoire of circulating lymphocytes using multiparameter flow cytometry.

III. To determine changes in circulating cytokine mediators of inflammation and immunity using Luminex assay.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive tremelimumab intravenously (IV) over 1 hour on day 1. Treatment repeats every 4 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients also receive durvalumab IV over 1 hour on day 1. Treatment repeats every 4 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients achieving disease control may restart treatment upon evidence of progressive disease, with or without confirmation.

ARM II: Patients undergo radiation therapy daily for 5 days over 1 week or for 3 fractions every other day for 1 week and then receive the same treatment as in Arm I.

After completion of study treatment, patients are followed up periodically.

Eligibility Criteria

Inclusion Criteria

• Written informed consent and any locally-required authorization (e.g.,) obtained from the subject prior to performing any protocol-related procedures, including screening evaluations
• Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2
• Hemoglobin ≥ 9.0 g/dL
• Absolute neutrophil count (ANC) ≥ 1.5 x 10⁹/L (≥ 1500 per mm³)
• Platelet count ≥ 100 x 10⁹/L (≥ 100,000 per mm³)
• Serum bilirubin ≤ 1.5 x institutional 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 hemolysis or hepatic pathology), who will be allowed only 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 unless liver metastases are present, in which case it must be ≤ 5 x ULN
• Serum creatinine clearance (CL) > 40 mL/min by the Cockcroft-Gault formula or by 24-hour urine collection for determination of creatinine clearance
• Female subjects must either be of non-reproductive potential (i.e., post-menopausal by history: ≥ 60 years old and no menses for ≥ 1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy upon study entry
• Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up

Exclusion Criteria

• Patients must have histologically or cytologically confirmed small cell lung cancer
• Patients must have measurable disease, defined as at least one lesion (excluding the lesion for XRT) that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as > 20 mm with conventional techniques or as > 10 mm with spiral computed tomography (CT) scan
• Patient must have failed or found to be intolerant of standard frontline platinum-based regimens and must not have received > 2 prior lines of therapy (nota bene [NB]: retreatment with a platinum-based doublet for sensitive relapse counts as another line therapy; however substitution of cisplatin with carboplatin or vice versa due to toxicity does not count as a separate regimen)
