Brief summary
The aim of the current study is to investigate whether adding nivolumab and ipilimumab after chemoradiotherapy helps to stop small cell lung cancer coming back.

You may be eligible for this study if you are an adult with confirmed small cell lung carcinoma.

If the study is suitable for you, you will commence treatment with chemotherapy and thoracic (chest) radiotherapy and prophylactic cranial irradiation (PCI/ brain) radiotherapy which are the standard of care treatment for SCLC. Following completion of the chemotherapy and radiotherapy part of your treatment you will have a CT scan to see if your cancer is shrinking or growing. If your cancer has grown your consulting doctor will discuss the most suitable treatment for you at that time.
If your cancer has not grown, you will go on to the next part of the study, and you will be randomised into one of two study groups:

Group 1: Nivolumab plus ipilimumab (experimental treatment)
Group 2: Observation (no further treatment)

If you take part in STIMULI, you will have a number of tests at the first study visit to confirm that the study is suitable for you. At each study visit, you will have various assessments, such as blood testing, urine testing. Computerised Tomography (CT) scans to assess your cancer will be performed every 2-3 months for the first 2 years and then less frequently.

This study will help researchers understand how well this treatment works and how severe the side effects are of the standard treatment (chemotherapy and radiotherapy) alone, compared with the standard treatment (chemotherapy and radiotherapy) followed by immunotherapy (nivolumab and ipilimumab) in patients with limited SCLC.
