A Clinical Trial of Durvalumab (MEDI4736) as 1st Line Therapy in Advanced Non-small Cell Lung Cancer Patients

Phase 2

Completed

Conditions: Non-Small Cell Lung Cancer NSCLC

Interventions: Drug: durvalumab

Registration Number: NCT02879617

Lead Sponsor: Academic Thoracic Oncology Medical Investigators Consortium

Brief Summary: This is a single-arm phase II clinical trial evaluating the safety and efficacy of the PD-L1 inhibitor durvalumab as first-line therapy in 47 patients with advanced NSCLC and ECOG Performance Status 2 (PS2).

Detailed Description: Durvalumab will be supplied in glass vials containing 500 mg of liquid solution at a concentration of 50 mg/mL for intravenous (IV) administration. Durvalumab will be administered at 1500 mg (fixed dose) every 4 weeks until disease progression, death, unacceptable toxicity or withdrawal of consent for a maximum of 12 months of therapy.

Patients must have measurable disease.
Patients must have not have received any prior therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) for the treatment of stage IV NSCLC.
Age ≥ 18 years at time of study entry.
ECOG performance status of 2.
Life expectancy of greater than 12 weeks.
Tissue available (archived or fresh tumor biopsy) for the PD-L1 assay.
Patients must have normal organ and marrow function as defined below:
- Absolute neutrophil count (ANC) ≥ 1.5 x 10^9/L (> 1500 per mm^3)
- Hemoglobin ≥ 9.0 g/dL
- Platelet count ≥ 100 x 10^9/L (>100,000 per mm^3)
- Serum bilirubin ≤ 1.5 x institutional upper limit of normal (ULN).
- AST (SGOT)/ALT (SGPT) ≤ 2.5 x ULN unless liver metastases are present, in which case it must be ≤ 5x ULN Serum creatinine CL>40 mL/min by the Cockcroft-Gault formula
Female subjects must either be of non-reproductive potential OR must have a negative serum pregnancy test upon study entry.
The effects of durvalumab on the developing human fetus are unknown. For this reason and because immunomodulatory agents are potentially teratogenic, sexually active women of child-bearing potential and men must agree to use adequate contraception (2 methods of effective contraception from screening) from screening, for the duration of study participation, and for at least 90 days following the last infusion of durvalumab.
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.
