Intervention model description: open, exploratory, multinational, phase 2 trial
Primary purpose: TREATMENT

Brief summary: The main aim is to identify and describe biomarkers in different sample types related to chemoradiation followed by durvalumab treatment for stage III PD-L1 negative and positive non-small cell lung cancer (NSCLC) patients' eligible for curatively intended chemoradiation.

The hypothesis is that clinical differences in course of disease reflect underlying biological characteristics.

Detailed description: This is an open, multinational, phase 2 trial to investigate the Properties of cancer cells before, during and after treatment with the investigational study drug durvalumab in patients with locally advanced non-small celled lung cancer (NSCLC). Both patients with high and low PD-L1 expression are allowed to participate. Durvalumab (PD-L1 inhibitor) will be administered after a period with standardtreatment with chemotherapy and radiationtherapy (chemoradiotherapy) for around 7 weeks. After maximum 5 weeks break after chemoradiotherapy, durvalumab will be given in the same dose to all patients for up to 12 months. The follow-up include a safety follow-up for up to five years, followed by a survival follow-up for up to a total of ten years.

   * Measured creatinine clearance (CL) \>40 mL/min or Calculated creatinine CL\>40 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance:

   Males:

   - Creatinine CL (mL/min) = Weight (kg) x (140 - Age) 72 x serum creatinine (mg/dL)

   - Creatinine CL (mL/min) = Weight (kg) x (140 - Age) x 0.85 72 x serum creatinine (mg/dL)
10. Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause.
11. Women of childbearing potential (WOCBP) should have a negative urine or serum pregnancy within 7 days prior to receiving the firs dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required. A woman is considered as WOCBP, i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy.
12. WOCBP should use an adequate method to avoid pregnancy
13. males who are sexually active with women of childbearing potential must agree to follow instructions for method(s) of contraception for a period of 90 days (duration of sperm turnover) / the time required for the investigational drug to undergo five half-lives
14. Patient 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:

1. Non-small cell lung cancer disease suitable for curative surgery
2. Significant cardiac, pulmonary or other medical illness that would limit activity or survival
3. Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study during the last 2 weeks.
