Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Durvalumab

Experimental: Treatment - Participants will receive 2 weeks of therapy with concurrent hypofractionated radiotherapy (30Gy/10#), weekly carboplatin (AUC2), weekly paclitaxel (50mg/m2) and durvalumab (1500mg) intravenously every 4 weeks, followed by durvalumab monotherapy continuing at 1500mg intravenously every 4 weeks until disease progression or 24 months of therapy. One to five metastases will be treated with stereotactic radiotherapy (24Gy/3#) 4 weeks after the completion of the chemoradiotherapy to the primary tumour. Monitoring of adherence to treatment will be done by attendance at booked appointments


Treatment: Drugs: Durvalumab
Durvalumab will be supplied by AstraZeneca as a 500 mg vial concentrate for solution for infusion. The solution contains 50 mg/mL durvalumab, 26 mM histidine/histidine-hydrochloride, 275 mM trehalose dihydrate, and 0.02% weight/volume (w/v) polysorbate 80; it has a pH of 6.0 and density of 1.054 g/mL. The label-claim volume is 10 mL.

Durvalumab is a sterile, clear to opalescent, colorless to slightly yellow solution, free from visible particles.

Investigational product vials are stored at 2°C to 8°C and must not be frozen. Investigational product must be kept in original packaging until use to prevent prolonged light exposure.

7. Body weight of greater than 30kg.

Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring adverse events or compromise the ability of the patient to give written informed consent.
21. Pregnancy, lactation, or inadequate contraception. Women must be post-menopausal, infertile, or use a reliable means of contraception to avoid pregnancy for 90 days after the last dose of durvalumab.

Sperm donation is not permitted for 180 days after the last dose of durvalumab and chemotherapy, or 90 days after the last dose of durvalumab monotherapy (whichever is the longer time period).
