About this study
This is a prospective, single-center phase II study evaluating sintilimab plus chemotherapy as induction therapy for unresectable stage IIIC non-small cell lung cancer (NSCLC). Treatment-naive eligible patients who signed informed consent were enrolled after MDT screening. Patients received 4 cycles of sintilimab 200 mg intravenously every 3 weeks combined with chemotherapy. Post-treatment MDT evaluation was performed. Resectable patients underwent primary tumor resection and mediastinal lymph node dissection 4-6 weeks after the 4th cycle. Postoperative supraclavicular radiotherapy and guideline-recommended adjuvant therapy were determined by MDT and investigators. Unresectable patients received concurrent chemoradiotherapy.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Sintilimab plus platinum-doublet chemotherapy in people with Non Small Cell Lung Cancer, run by Sun Yat-sen University.
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 2 inclusion and 3 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: opening soon, as of the sponsor's last update on 22 May 2026. Status can change between updates, so confirm with the study contact before making plans.
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?
Contact Ling Cai (+8613602766093, cailing@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Surgical conversion rate (time frame: Up to 12 weeks after enrollment). 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 22 May 2026.
