This is a Phase II, open-label, multi-centre study to determine the safety of a fixed dose of

This is a Phase II, open-label, multi-centre study to determine safety of a fixed dose of
Durvalumab (MEDI4736) (1500 mg) monotherapy in participants with unresectable Stage III NSCLC
who have not progressed following definitive, platinum-based sCRT. Approximately, 150
participants will be treated with the study drug in Europe and North America. Participants
will be in complete response (CR), partial response (PR), or have stable disease (SD)
following definitive, platinum-based sCRT, as assessed by the Investigator and further
supported by the screening imaging radiological assessment. Participants must not have
progressed following definitive, platinum-based sCRT; radiation therapy must be completed
within 42 days prior to first Investigational product (IP) dose administration. Participants
must have histologically- or cytologically-documented NSCLC and locally-advanced,
unresectable Stage III disease. Participants will be treated with the study drug in 2
cohorts: approximately 100-120 participants in the World Health Organization/Eastern
Cooperative Oncology Group Performance Status (WHO/ECOG PS) 0 to 1 Cohort and up to 30
participants in the WHO/ECOG PS 2 Cohort.

requirements and restrictions listed in the ICF and in this protocol.
2. Provision of signed and dated, written ICF prior to any mandatory study specific
procedures, sampling, and analyses.
3. Provision of signed and dated written genetic informed consent prior to collection of
sample for genetic analysis (optional).
4. 18 years or older at the time of signing the ICF.
5. Histologically- or cytologically-documented NSCLC with locally-advanced, unresectable
Stage III disease (according to the IASLC Staging Manual Version 8 [IASLC 2016]).
Positron emission tomography (PET)/CT, MRI of the brain, and endobronchial ultrasound
with biopsy are highly encouraged at diagnosis.
6. Receipt of sCRT which must have been completed within 42 days prior to first IP dose
administration in the study.
1. The platinum-based chemotherapy regimen must contain cisplatin or carboplatin and
1 of the following agents: etoposide, vinblastine, vinorelbine, a taxane
(paclitaxel or docetaxel), or pemetrexed, according to the local standard of care
(SoC) regimens. Platinum-based chemotherapy containing cisplatin or carboplatin
and gemcitabine is permitted under certain conditions - refer to bullet point
2. Patients must have received at least 2 cycles of platinum-based chemotherapy
before radiation therapy. The interval between administration of the last dose of
chemotherapy regimen and start of radiation therapy must be no more than 6 weeks.
Consolidation chemotherapy after radiation is not permitted.
(i) If the patient's platinum-based chemotherapy contained gemcitabine, no overlap
between chemotherapy and radiation therapy is permitted.
(ii) If the patient's platinum-based chemotherapy contained any of the agents listed
in (a) other than gemcitabine, an overlap of 1 cycle of chemotherapy and radiation
therapy is acceptable.
(c) Patients must have received a total dose of radiation of 60 Gy ±10% (54 Gy to 66
Gy). Sites are encouraged to adhere to mean organ radiation dosing as follows: (i)
Mean lung dose <20 Gy and/or V20 <35%; (ii) Mean oesophagus <34 Gy; (iii) Heart V45
<35% or V30 <30%. Note: Sites should be aware of the recent RTOG 0617 Study data
demonstrating that doses higher than 60 Gy may be associated with greater toxicity and
(d) Patients with WHO/ECOG PS 2 or chronic lung disease (pulmonary emphysema or
chronic obstructive pulmonary disease) must have received a V20 <25%.
7. Patients must not have progressed following platinum-based sCRT, as per Investigator
assessed RECIST 1.1 criteria. . In order to assess disease progression, the baseline
imaging (CT/MRI) used for Screening purposes should be compared against the most
recently performed scan that allows physician assessment as per RECIST 1.1 criteria.
If an intermediate scan taken between chemotherapy and radiotherapy is available and
that scan is suitable for physician assessment as per RECIST 1.1 criteria, then this
scan should be used.
1. Patients with measurable disease and/or non-measurable and/or no evidence of
disease (NED) assessed at baseline by CT/MRI will be entered in this study.
2. Prior irradiated lesions may be considered measurable and selected as TLs
provided they fulfil the other criteria for measurability.
