• Patients with Grade ≥2 pneumonitis from prior chemoradiation therapy will be excluded from randomization;
• Current or prior use of immunosuppressive medication within 28 days before the first dose of toripalimab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. Systemic steroid administration required to manage toxicities arising from radiation therapy delivered as part of the previous chemoradiotherapy for SCLC is allowed;
• Prior exposure to any anti-programmed cell death protein(PD)-1 or anti-PD-L1 antibody;
• Recent major surgery within 4 weeks prior to entry into the study (excluding the placement of vascular access);

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression-free Survival	Time from the date of randomisation until death from any cause or first documented disease progression determined by RECISIT v1.1	2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival	Time from the date of randomisation until death from any cause	2 years
Objective Response Rate	Best overall response (CR or PR) rate determined by RECISIT v1.1 across all assessment time-points during the period from randomisation to termination of protocol specific treatment	2 years
Duration of Response	Time from the date of first documented response of CR or PR until first documented progression or death, determined by RECISIT v1.1	2 years
Adverse Event	Number of participants with treatment-related adverse events determined by CTCAE v4.0	2 years
Quality of Life (EORTC QLQ-C30)	Quality of life score assessed by Quality of Life Questionnaire-Core 30 proposed by The European O-rganization for Reasearch and Treatment of Cancer. EORTC QLQ-C30 contained 30 items. Items 29 and 30 are rated on a scale of 1 to 7. The other items are divided into four grades: totally not, a little bit, a lot and very much, and scored on a scale of 1 to 4. For functional and overall health domain, a higher score refers to a better life quality; for symptom domain, a higher score refers to a worse life quality.	2 years
Quality of Life (EORTC QLQ-LC13)	Quality of life score assessed by Quality of Life Questionnare-Lung Cancer 13 proposed by The European O-rganization for Reasearch and Treatment of Cancer. EORTC QLQ-LC13 contained 13 items assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. Each item is scored on a scale 0 to 100, where 0 indicates no symptoms and 100 indicates the worst possible symptoms.	2 years
ECOG performance status	Performance status score assessed by Zubrod-ECOG-WHO method, range 0-5. A higher score refers to a worse quality of life.	2 years
