About

This is a phase III, multicenter, double-blinded, placebo-controlled study of platinum（Cisplatin or Carboplatin） plus etoposide with or without toripalimab as first Line therapy in patients with extensive stage small cell lung cancer.

The purpose of this study is to evaluate the safety and efficacy of toriplimab in combination with platinum（Cisplatin or Carboplatin） plus etoposide in treatment naive extensive stage small cell lung cancer.

Participants will receive asigned study treatment until progressive disease (PD) as assessed by the investigator using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST v1.1).

Enrollment: 442 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

4. No prior treatment or immunocheckpoint inhibitors for ES-SCLC;
5. Treatment-free for at least 6 months since last chemo/radiotherapy, among those treated (with curative intent) with prior chemo/radiotherapy for limited-stage SCLC；
6. Patients with asymptomatic brain metastases who have received previous treatment
7. Has provided tumor tissue samples
8. Estimated survival time ≥8 weeks;
9. There is at least one measurable lesion that conforms to RECIST criteria v1.1.For lesions that have received previous radiation therapy, the lesion can only be included in the measurable lesion if the disease progression is clear after radiotherapy and the lesion is not the only measurable lesion.

3. Subjects with active or untreated central nervous system (CNS) tumor metastasis;
4. Spinal cord compression not definitively treated with surgery and/or radiation or previously diagnosed and treated spinal cord compression without evidence that disease has been clinically stable for ≥ 1 week prior to randomization
5. Cancerous meningitis;
6. Uncontrolled or symptomatic hypercalcemia;
7. Other malignant tumors within 5 years prior to the first dose of study treatment
8. Subjects with any active, known or suspected autoimmune disease;
9. History of idiopathic pulmonary fibrosis, drug-induced pneumonitis,or evidence of active pneumonitis .
10. Subjects who received major surgery within 28 days prior to enrollment or were not fully recovered from prior surgery;
11. Significant cardiovascular disease, such as New York Heart Assoc
