Brief summary
This prospective clinical study aims to evaluate and observe the efficacy and safety of Atezolizumab combined with Apatinib in maintenance therapy for extensive-stage small cell lung cancer using a single-arm trial design. The study is planned to be conducted in Shaanxi Province, China, with an initial target enrollment of 60 patients. The study commenced in February 2024, and recruitment is expected to conclude around December 2025, with the trial anticipated to end by December 2026. Assuming no occurrences such as withdrawal of informed consent by subjects, intolerable adverse drug reactions, or investigator-assessed unsuitability for further participation, each participant's estimated duration of study treatment will continue until radiographically confirmed tumor progression.
Interventions
Each treatment cycle spans 3 weeks. Sequential medication administration begins on the first day of each cycle: Atezolizumab is administered at a dosage of 1200mg on day 1, every 3 weeks, while Apatinib is given orally at a dosage of 250mg daily from day 1 to day 14, every 3 weeks, with a one-week hiatus following two weeks of continuous intake. Administration timing allows for a window of ±5 days. Subjects are required to undergo comprehensive assessments, including vital signs monitoring, anthropometric measurements, physical examinations, laboratory analyses, and performance status evaluations, to assess treatment tolerability for continuation.

Eligibility
Inclusion criteria
1. Voluntary participation with signed informed consent and good compliance for follow-up. 2. Age between 18 and 75 years old. 3. Histologically or cytologically confirmed extensive-stage small cell lung cancer (LS-SCLC) according to the AJCC 8th edition or VALG phase II staging criteria. 4. ECOG performance status score: 0 to 2. 5. Absence of disease progression after receiving 4-6 cycles of platinum-based chemotherapy combined with Atezolizumab induction therapy. 6. Recovery of non-hematologic adverse reactions to grade 1 (except for alopecia, skin pigment changes, or as determined by the investigator) following induction therapy. 7. Time from the end of induction treatment (last dose) to initiation of maintenance treatment ≤ 6 weeks. 8. At least one measurable lesion assessed by the investigator according to RECIST 1.1. 9. Expected life expectancy of at least 3 months. 10. Normal function of major organs, meeting the following criteria: * Bone marrow function: Absolute neutrophil count (ANC) ≥ 1.5×10\^9/L (grade 1 according to CTCAE 5.0); platelets ≥ 100×10\^9/L; hemoglobin \> 80g/L. * Renal function: Creatinine ≤ 1.5 times the upper limit of normal (ULN), grade 1 according to CTCAE. Note: If creatinine is greater than 1.5 times the ULN, creatinine clearance must be \> 50ml/min. * Liver function: Bilirubin ≤ 1.5 times ULN (grade 1 according to CTCAE), patients with Gilbert's syndrome bilirubin ≤ 3.0 times ULN; AST and ALT ≤ 3.0×ULN. * Coagulation indicators: International normalized ratio (INR) ≤ 1.55 (if the patient is receiving a stable dose of therapeutic warfarin or low molecular weight heparin, INR is usually between 2 and 3), PTT \< 1.2 times ULN. 11. Women of childbearing potential must agree to use contraception during the study and for 6 months after the end of the study (such as an intrauterine device, contraceptive pills, or condoms); serum or urine pregnancy test must be negative within 1 week before enrollment, and must be non-lactating patients; men must agree to use contraception during the study and for 6 months after the end of the study.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival | Progression-free survival (PFS) analysis based on investigator assessment per RECIST 1.1, and will be assessed up to 2 years | Progression free survival (PFS) refers to the time from recording the first chemotherapy treatment to the date of disease progression, as assessed by researchers. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival | The maximum time from receiving treatment to dying for any reason is 4 years. | Overall survival (OS) refers to the time that researchers evaluate from recording the first chemotherapy to death (of any cause). |
| Objective response rate | Data obtained up until progression, or the last evaluable assessment in the absence of progression, will be assessed up to 1 years | Per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) using Investigator assessments, is defined as the number (%) of patients with response of Complete Response or Partial Response, will be assessed up to 1 years. |
| Complete Response rate | up to 1 years | Per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) using Investigator assessments, is defined as the number (%) of patients with response of Complete Response, will be assessed up to 1 years. |
| Duration of Response | Duration of Response(DoR)analysis based on investigator assessment per RECIST 1.1, and will be assessed up to 1 years | Duration of Response(DoR)refers to the time from the first assessment as CR or PR to the first assessment as PD or (due to any reason) death |
