Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Radiation: Thoracic Radiotherapy
Participants will receive thoracic radiotherapy to a dose of 30 Gray (Gy) in 10 fractions (3 Gy per day) concurrently with cycle 3 or 4 of chemo-immunotherapy (Group 1).
Participants who are unsuitable for concurrent radiotherapy may receive consolidation radiotherapy. Consolidation thoracic radiotherapy will be administered to a dose of 30 Gy in 10 fractions, following 4 cycles of chemo-immunotherapy (Group 2).
Treatment fractions will be delivered daily, where treatment should be completed within 15 days (9-10 fractions a fortnight).

Drug: Etoposide with Carboplatin or Cisplatin (Chemotherapy)
The chemotherapy in this study is a standard treatment for extensive-stage small-cell lung cancer (EC-SCLC). The combination of chemotherapy (etoposide + carboplatin or etoposide + cisplatin) which the participant will receive is dependent on what is standard at the treatment centre.
Chemotherapy will be administered via an intravenous infusion every 3 weeks (21 days) for 4 cycles.

Drug: Durvalumab (Immunotherapy)
The immunotherapy in this study is a standard treatment for ES-SCLC.
Participants will receive a dose of 1500 mg of Durvalumab via an intravenous infusion every 3 weeks (21 days) for 4 cycles, concurrently with chemotherapy.
A 1500 mg maintenance dose of Durvalumab will be administered every 4 weeks after completion of chemotherapy (monotherapy).

Outcomes
Primary outcome [1] 326203 0
Safety of chemo-immunotherapy with concurrent thoracic radiotherapy:
Group 1 and Group 2 will be compared for the presence of toxicity, whereby the proportion of grade 3 or higher pneumonitis and grade 3 or higher oesophagitis will be monitored using the NCI Common Terminology Criteria for Adverse Events v5.
Timepoint [1] 326203 0
From date of consent to 90 days after trial treatment is discontinued
Primary outcome [2] 326893 0
Feasibility of chemo-immunotherapy with concurrent thoracic radiotherapy:
Group 1 and Group 2 will be compared for the proportion of participants which received concurrent radiotherapy vs the proportion of participants which did not receive concurrent radiotherapy. This will be assessed by the audit of medical records.

Safety/efficacy
Statistical methods / analysis
A single arm of up to 30 evaluable participants given thoracic radiotherapy concurrent with chemo-immunotherapy will be enrolled. Participants not suitable for concurrent thoracic radiotherapy due to field size after cycle 2 may receive sequential radiotherapy. Accounting for a 15% non-evaluable rate, up to 35 participants will be enrolled. An independent data and safety monitoring committee will review the data and assess safety and feasibility following initial 10 participants. As a guide, a toxicity of greater than or equal to Grade 3 oesophageal toxicity in less than or equal to 20% of participants and greater than or equal to grade 3 pneumonitis in less than or equal to 10% would be considered reasonable for progression to a Phase III study. Less than or equal to 20% treatment discontinuation of systematic therapy secondary to radiation toxicities and over 75% participants having disease which can be encompassed within a reasonable radiation portal and complete full dose of radiation therapy is considered feasible.

A second interim analysis will occur after accrual of 20 participants to determine if the trial can be stopped early for meeting the safety requirements. The primary outcome of the study is safety and feasibility and OS will be assessed as secondary endpoints.
A pre-defined subgroup analysis of toxicity will be performed on Group 1 (concurrent thoracic RT) vs Group 2 patients (consolidation thoracic RT).

Summary
Brief summary
This trial aims to determine the safety, feasibility, and efficacy of a combination of chemotherapy, immunotherapy, and chest radiation therapy in extensive stage small cell lung cancer.

Who is it for?
You may be eligible for this study if you are 18 or above and have untreated extensive stage small cell lung cancer.

Study details
Participants will be given durvalumab (an immunotherapy drug) concurrently with 4 cycles of cisplatin/carboplatin and etoposide chemotherapy, which is given as in injection every three weeks over approx. 12 weeks.
Maintenance treatment with durvalumab alone will continue every 4 weeks after the completion of the chemotherapy cycles until there is evidence of disease progression.

Participants will also receive 10 chest radiotherapy sessions, which will take approx. 2 weeks to complete (given either concurrently with cycle 3 or 4 of chemotherapy (called concurrent radiotherapy) or within 6 weeks of finishing chemotherapy (called consolidation radiotherapy). Fractions are expected to be delivered daily. When RT is to start depends on the location and size of the area to be treated).
Throughout the study, participants will be monitored regularly for any adverse effects, and for progression of disease using a number of imaging techniques.

It is hoped that this study may demonstrate that chest radiation is safe and beneficial when given in combination with chemotherapy and immunotherapy for the treatment of extensive stage small cell lung cancer.
