Inclusion criteria

Inclusion criteria: 1. Age >= 18 years, regardless of gender; 2. Small cell lung cancer (SCLC) confirmed by histology or cytology; 3. Extensive-stage small cell lung cancer, classified as stage IV (any T, any N, M1a/b/c) according to the 8th edition of the AJCC, or T3-4 due to multiple pulmonary nodules or tumor/nodule volume too large to be included in a tolerable radiotherapy plan; 4. At least one measurable lesion on imaging#RECIST 1.1; 5. Have not received any systemic anti-tumor treatment for extensive-stage diseases in the past. For patients who have received adjuvant/neoadjuvant chemotherapy in the past, or have received curative radiotherapy and chemotherapy for advanced diseases, if there is a gap of at least 6 months between disease progression or recurrence and the end of the last chemotherapy drug treatment, they are eligible to be included in this study; 6. Patients with asymptomatic brain metastases or brain metastases whose symptoms have stabilized after treatment; 7. Subjects are allowed to receive palliative radiation therapy (including cranial radiation therapy for symptomatic brain metastases), but the radiation therapy must be completed at least one week before enrollment; 8. The laboratory test results meet the following criteria: Hemoglobin >= 90 g/L, neutrophil count >= 1.5 × 10^9/L, platelet count >= 100 × 10^9/L; Creatinine clearance rate (CrCl) >= 60 mL/min (as calculated using the CockcroftGault formula); Total bilirubin = 30 g/ L; International normalized ratio (INR) or prothrombin time (PT) = 3 months; 11. For Female Participants: All Female Participants with potential fertility must have a negative serum pregnancy test result during the screening period, and must take reliable contraceptive measures from signing the informed consent form until 3 months after the last dose; 12. Understand and sign the informed consent form;

Exclusion criteria

Exclusion criteria: 1. Diagnosed with malignant diseases other than SCLC within 5 years prior to the first administration (excluding curative basal cell carcinoma, squamous cell carcinoma, and/or excised carcinoma in situ); 2. Mixed SCLC and NSCLC confirmed by histology or cytology; 3. Currently participating in interventional clinical research treatment, or having received other investigational drugs or used investigational devices within 4 weeks prior to the first administration; 4. Previously received the following therapies: anti-PD-1, anti-PD-L1, or anti-PD-L2 drugs, or drugs that stimulate or synergistically inhibit T cell receptors (such as CTLA-4, OX-40, CD137); 5. Within 2 weeks before the first administration, the individual has received systematic systemic treatment with traditional Chinese patent medicines and simple preparations with anti lung cancer indications or drugs with immunomodulatory effects (including thymosin, interferon, interleukin, except for local use to control pleural effusion and pleural effusion); 6. Within 2 years prior to the first administration, the individual has been an active autoimmune disease requiring systemic treatment (such as the use of disease relieving drugs, corticosteroids, or immunosuppressants). Alternative therapies (such as thyroid hormone, insulin, or physiological glucocorticoids used for adrenal or pituitary insufficiency) are not considered systemic treatments; 7. Within 7 days prior to the first administration of the study, the individual was receiving systemic corticosteroid therapy (excluding topical corticosteroids via nasal spray, inhalation, or other routes) or any other form of immunosuppressive therapy; Note: Physiological doses of glucocorticoids (= 10 mg/day of prednisone or equivalent) are allowed to be used; 8. Individuals who are known to be allergic to the active ingredients or excipients of the investigational drugs, such as trilaciclib, envafolimab, etoposide, carboplatin, etc; 9. Patients with clinically uncontrollable pleural/peritoneal effusion (those who do not require drainage or have no significant increase in effusion after stopping drainage for 3 days can be enrolled); 10. Known history of human immunodeficiency virus (HIV) infection (i.e. HIV 1/2 antibody positive) or untreated active HBV, HCV; 11. Pregnant or lactating female participants; 12. Uncontrolled ischemic heart disease or clinically significant congestive heart failure (NYHA class III or IV); 13. Stroke or cardiovascular events within the first 6 months of enrollment; 14. QTcF>480msec, for patients implanted with ventricular pacemakers, QTcF>500msec; 15. Previously received hematopoietic stem cell or bone marrow transplantation; 16. Medical history or disease evidence that may interfere with the trial results, hinder the full participation of the subjects in the study, abnormal treatment or laboratory test values, or other situations that the researchers believe are not suitable for inclusion. The researchers believe that there are other potential risks and they are not suitable to participate in this study;
