A Study to Compare Durvalumab vs Placebo Following Stereotactic Body Radiation Therapy in Early Stage Non-small Cell Lung Cancer Patients


About this study

The purpose of this study is to evaluate the effectiveness and safety of durvalumab versus placebo following Stereotactic Body Radiation Therapy  (SBRT) in patients with unresected clinical Stage I/II lymph node-negative Non-small Cell Lung Cancer (NSCLC).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Patients are eligible to be included in the study only if all of the following inclusion criteria and none of the exclusion criteria apply. 
Informed consent

1. Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol
2. Provision of signed and dated written ICF prior to any mandatory study specific procedures, sampling, and analyses
3. Genetics research study (optional) For inclusion in the optional (DNA) genetics research study, patients must fulfil the following criteria:
− Provide informed consent for the optional genetic sampling and analyses. If a patient declines to participate in the optional genetics research, there will be no penalty or loss of benefit to the patient. A patient who declines optional genetics research participation will not be excluded from any other aspect of the main study.
Note: The optional genetic research study is not conducted in China.
4. Age ≥18 years at the time of screening. For patients aged <20 years and enrolled in Japan, a written informed consent should be obtained from the patient and his or her legally acceptable representative.
Type of patient and disease characteristics
5. Histologically or cytologically documented Stage I to II NSCLC (American Joint Committee on Cancer Stage [AJCC Cancer Staging Manual, Eighth Edition], with clinical Stage I/II lymph node-negative (T1 to T3N0M0) disease and planned to receive definitive treatment with SBRT. In order to be eligible for this trial, patients
should be:
Medically inoperable as determined by physician or
Medically operable with patient refusal of surgery
Patients with medically operable disease who choose to have SBRT are also eligible.
6. Planned SoC SBRT as definitive treatment (see Appendix H) using one of the following doses:
For peripheral tumors: 54 Gy total dose delivered in 3 fractions, 42 or 48 Gy total dose delivered in 4 fractions, or 50 or 55 Gy total dose delivered in 5 fractions.
For central tumors: 50 or 55 Gy total dose delivered in 5 fractions, or 50 or 60 Gy total dose delivered in 8 fractions.
7. World Health Organization (WHO)/Eastern Cooperative Oncology Group (ECOG) PS of 0, 1, or 2 at enrollment and randomization
8. Tumor sample requirements:
- Provision of archived tumor tissue block or slides (6 newly cut unstained slides is strongly encouraged) ≤6 months old.
If an archival sample is not available, provision of a recent (≤3 months) tumor biopsy is encouraged, provided that a biopsy procedure is technically feasible, and the procedure is not associated with unacceptable clinical risk.
If archival tumor tissue block, slides are unavailable, cell blocks or slides from fine needle aspirate (FNA) samples ≤6 months old will be accepted.
In situation when tissue from initial biopsy is exhausted, rebiopsy is encouraged but not mandatory for enrolling onto study if biopsy is associated with unacceptable clinical risk
- For China: Only tumor slides (sectioned from biopsy or FNA cell blocks) should be provided.
9. Patients with central or peripheral lesions are eligible. Central lesions are defined as tumor within or touching the zone of the proximal bronchial tree, defined as a volume of 2 cm in all directions around the proximal bronchial tree (carina, right and left main bronchi, right and left upper lobe bronchi, intermedius bronchus, right middle lobe bronchus, lingular bronchus right, and left lower lobe bronchi). Patients with Ultra-central tumors are NOT eligible. Ultra-central tumors are defined as tumors abutting the trachea, mainstem bronchus, or esophagus.
10. Patients with a history of metachronus stage I/II (T1-T3N0M0) NSCLC treated definitively with surgery only or SBRT only >1 year prior to enrollment are eligible. Patients with a previous history of SBRT to the lung are eligible provided additional radiation is deemed safe by the treating radiation oncologist and after consultation with the Study Physician/International Coordinating Investigator. Patients with synchronous NSCLC tumors are allowed when there is maximum of 2 intrathoracic lesions. Each lesion will be staged separately according to TNM system and identified in CRF. Please see section 5.3. Lesions must be treated with the same dose/fraction to each lesion and meet the Organ at Risk constraints identified in the study protocol.
11. Adequate organ and marrow function as defined below prior to randomization:
Hemoglobin ≥9.0 g/dL
Absolute neutrophil count ≥1.0 × 109/L
Platelet count ≥75 × 109/L
Serum bilirubin ≤1.5 × the upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert’s syndrome, who will be allowed in consultation with their physician.
ALT and AST ≤2.5 × ULN within 2 weeks prior to randomization
Measured creatinine clearance (CL) >30 mL/min or calculated CL >30 mL/min as determined by Cockcroft-Gault (using actual body weight)
Creatinine CL (mL/min) =         Weight (kg) × (140 - Age)  /  72 × serum creatinine (mg/dL)
Creatinine CL (mL/min) = Weight (kg) × (140 - Age) / 72 × serum creatinine (mg/dL) x0.85
12. Must have a life expectancy of at least 12 weeks
13. The following staging studies must be done within 10 weeks before randomization:
Positron emission tomography (PET)/CT scan from at least the base of the skull to mid-thigh is required for staging purposes. If PET scan not previously performed, may be performed during screening to ensure adequate clinical staging.
Patients with hilar or mediastinal lymph nodes ≤1 cm and no abnormal hilar or mediastinal uptake on PET will be considered N0. Mediastinal lymph node sampling by any technique is allowed but not required. Patients with >1 cm hilar or mediastinal lymph nodes on CT or abnormal PET (including suspicious but nondiagnostic uptake) may still be eligible if directed tissue biopsies of all abnormally identified areas are negative for cancer.
