  • 7. The primary driver genes must not harbor sensitive mutations (including EGFR (exon 19 deletion, exon 21 L858R point mutation, exon 20 insertion, etc.), ALK fusion, ROS1 fusion, MET exon 14 skipping mutation, HER2 exon 20 mutation, BRAF V600E mutation, RET fusion, NTRK fusion). For non-squamous NSCLC, a prior tissue-based common genetic testing report must be provided; otherwise, tumor tissue samples (archived or fresh, primary or metastatic) must be collected prior to enrollment for genetic mutation status assessment (at a local laboratory or central laboratory). For squamous NSCLC subjects with a smoking history or current smoking status, if the prior primary driver gene mutation status is unknown, no corresponding testing is required prior to enrollment, and the status shall be considered negative.
  • 8. No prior systemic antitumor therapy or chest radiotherapy for NSCLC.
  • 9. At least one measurable lesion according to RECIST v1.1, and such lesions must be suitable for repeated accurate measurement per RECIST v1.1 criteria. -10. Subjects must provide tumor tissue samples diagnosed as locally advanced tumors at the time of diagnosis or thereafter, including archived or freshly obtained uncolored formalin-fixed paraffin-embedded (FFPE) pathological sections (preferably recently obtained tumor tissue samples), approximately 10-25 sections (of which approximately 10-15 sections are required for EGFR and ALK testing, and approximately 10 sections for PD-L1 expression testing; however, additional sections must be provided if the central laboratory determines that the sample is insufficient for testing), or fresh tumor tissue specimens (frozen in liquid nitrogen for omics research). Tumor lesions used for fresh biopsy should not be designated as RECIST v1.1 target lesions unless the lesion is the only measurable lesion. For archived samples, collection must occur after the last systemic treatment, and the collection site must not have undergone radiotherapy. Note: If a subject's archived sample does not meet the above requirements, the investigator may determine that the biopsy does not serve the subject's best interests and may, after discussion with the project team, permit the use of the archived sample.
  • 11.Fertile female subjects must have undergone a urine or serum pregnancy test within 7 days prior to the first medication administration (if the urine pregnancy test result is not negative, a serum pregnancy test must be performed, with the serum result serving as the definitive determination), and the result must be negative. If a fertile female subject has sexual intercourse with an unmarried male partner, she must have used an acceptable contraceptive method since the start of screening and must agree to continue using contraception for 120 days after the last administration of the antitumor drug; whether contraception should be discontinued after this period should be discussed with the investigator.
  • 12. If an unmarried male subject has sexual intercourse with a fertile female partner, he must have used an effective contraceptive method from the start of screening until 120 days after the last administration; whether contraception should be discontinued after this time point should be discussed with the investigator.
  • 13. The subject must be willing and able to comply with all scheduled visits, treatment regimens, laboratory tests, and other study requirements.

About this study

Official title: Comparison of the Efficacy and Safety of Induction Benmelstobart Plus Anlotinib and Chemotherapy Followed by Concurrent Chemoradiotherapy and Benmelstobart Maintenance Versus Concurrent Chemoradiotherapy Followed by Benmelstobart Maintenance in Patients With Unresectable Stage III NSCLC: A Randomized, Controlled, Multicenter Phase II Clinical Study

The goal of this clinical trial is to compare the efficacy and safety of induction Benmelstobart plus Anlotinib and chemotherapy followed by concurrent chemoradiotherapy (CCRT) and subsequent Benmelstobart maintenance versus CCRT followed by Benmelstobart maintenance in patients with unresectable stage III NSCLC. Additionally, high-throughput sequencing and multi-omics analysis will be performed on patient-derived tissue and blood samples. By integrating baseline characteristics with clinical data, we aim to identify key determinants of treatment efficacy and prognosis, thereby establishing a precision evaluation system for therapeutic outcomes.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Benmelstobart and benmelstobart combined with chemotherapy and anlotinib in people with NSCLC, run by The Third Xiangya Hospital of Central South 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 12 inclusion and 25 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 11 Jun 2026. 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?

Contact Xuewen Liu (+8618711033808, aveinliu@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-Free Survival (PFS) (time frame: The duration from initiation of antitumor therapy until the documentation of disease progression (according to RECIST v1.1) or death from any cause (whichever occurs first).Up to 60 months from randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07643350, which also lists 5 linked publications.

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 11 Jun 2026.
