About this study
Official title: Sequential Adebrelimab Combined With Apatinib as Consolidation Therapy Following Concurrent Chemoradiotherapy in Limited-Stage Small Cell Lung Cancer: A Prospective, Single-Arm, Multicenter Phase II Clinical Study
The study includes the screening period (from the time the subject signs the informed consent form to no more than 28 days before the first dose, imaging evaluations are allowed within 28 days before the first dose, and 5-14 days after the last radiotherapy/chemotherapy treatment, as close as possible to the treatment start date and the start of the study treatment), tumor tissue biopsy collection based on the subject's hospital, with preferred samples obtained within ≤3 months, but archived samples within 6 months before the first dose are also acceptable. The treatment period (until disease progression/worsening or confirmed radiological disease progression, or withdrawal for any reason) and the follow-up period (from the last dose to 36 months, including safety follow-up and survival follow-up).
Screening Period: Subjects who have received 2-4 cycles of platinum-based concurrent or induction chemotherapy (cCRT) and are evaluated as having non-progressive disease after cCRT, with the cCRT treatment ending within 1-42 days before the first dose, and the last radiotherapy session as the final end time. Consolidation chemotherapy after radiotherapy is not allowed.

Screening evaluation must be performed within 28 days before the first dose to determine eligibility. Tumor tissue samples should be collected based on the subject's hospital. The preferred samples are archived or freshly obtained tumor tissue wax blocks or pathological biopsy slides within ≤3 months, but archived samples within 6 months before the first dose are also acceptable.
Treatment Period: Each treatment cycle is 3 weeks. Atezolizumab 1200mg is administered via intravenous infusion, and Apatinib 250mg is taken orally after meals, once daily, for continuous use.
Subjects must undergo a comprehensive examination at the end of the study treatment or when withdrawing from the study, including vital signs, physical examination, laboratory tests, quality of life assessment, clinical tumor imaging evaluation (CT or MRI), and other necessary checks.
Follow-up Period: After the study treatment ends or the subject withdraws from the study, safety follow-up should be conducted. Subjects should be followed up every 30±7 days until 90 days. The first (30±7 days after withdrawal from the group) safety visit must be conducted at the research center, and vital signs, physical examination, laboratory tests, etc., should be assessed for AEs, concomitant medications, and supportive treatments. The other two visits (60±7 days and 90±7 days after withdrawal from the group) will be conducted by telephone, collecting survival information, AEs, concomitant medications, and supportive treatments.
After the safety follow-up is completed, subjects will be followed up every 3 months by phone to monitor survival status until death, loss to follow-up, withdrawal of informed consent, observation for 3 years, or termination of the study.
Read the detailed description
Dosing Regimen： Adebrelimab:Administered by intravenous infusion at a fixed dose of 1200 mg. The infusion should be completed within 30-60 minutes, with a maximum duration of 2 hours. The first dose is given on Day 1, with subsequent doses repeated every 3 weeks. Dose adjustments (either up or down) are not allowed during the study. A maximum delay of 9 weeks for treatment is allowed, or treatment may be terminated.
Apatinib: 250 mg, taken orally after meals, once daily, continuously. The investigator may temporarily pause the dose or adjust the administration schedule based on symptomatic treatment, such as changing to an every-other-day (qod) schedule or a 5-day-on, 2-day-off regimen. Once toxicity resolves, treatment may resume at the original dose.
The combined treatment of Adebrelimab + Apatinib for consolidation therapy should not exceed 24 months in total.
Primary Outcome Measure Progression-free survival (PFS) as assessed by the investigator (according to RECIST 1.1).
Secondary Outcome Measures
- Efficacy:Overall survival (OS), 12-month/24-month/36-month OS rates, 12-month/18-month PFS rates (according to RECIST 1.1).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Adebrelimab + Apatinib in people with Limited-stage Small Cell Lung Cancer (LS-SCLC), run by Second Affiliated Hospital of Nanchang University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: enrolling by invitation, as of the sponsor's last update on 14 Jan 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PFS assessed by the investigator (time frame: From enrollment to 3 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2025.
