What is being measured
The primary outcome is the main question the study is designed to answer.
Overall survival (OS)
Time from randomization to death for any reason in a clinical trial.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Secondary outcomes (8)
Objective Response Rate (ORR)
Objective Response Rate (complete response (CR) + partial response (PR)), as assessed by Response Evaluation Criteria in Solid Tumors (RECIST 1.1), refers to the percentage of study subjects who achieve a complete response or partial response.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Disease Control Rate(DCR)
Percentage of participants achieving complete response (CR) or partial response (PR) and stable disease (SD) after treatment.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Duration of Response(DOR)
DoR (per RECIST 1.1) is defined as the time from the date for first documented response of complete response (CR) or partial response (PR) to the date of first documented of disease progression or death, whichever occurs first.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Progression-free Survival(PFS)
According to the evaluation criteria of RECIST V1.1 (solid tumour),Time from first dose to disease progression or death from any cause.It was used to evaluate Time of disease no-progression or Drug resistance .
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Occurrence of adverse event (AE) and serious adverse event (SAE)
Adverse event (AE) will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 5.0.The safety profile of combination therapy will be assessed by monitoring the adverse event (AE) and serious adverse event (SAE).
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (90 days after drug withdrawal or before the start of new anti-tumor therapy)
Cmax
Maximum drug concentration in plasma after administration.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Tmax
After administration,Time to reach maximum drug concentration in plasma.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)
Immunogenicity
The immunogenicity is evaluated by the incidence of anti-drug antibodies (ADA) and neutralizing antibodies (if applicable) in subjects.Immunogenicity refers to the performance that can elicit an immune response.
Measured: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing LBL-024 for Injection, Etoposide injection and Cisplatin injection in people with Advanced Extrapulmonary Neuroendocrine Carcinoma, run by Nanjing Leads Biolabs Co.,Ltd at 36 sites 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 6 inclusion and 9 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 19 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 36 sites 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 Lin Shen (010-88121122, doctorshenlin@sina.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Overall survival (OS) (time frame: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (28 days after drug withdrawal or before the start of new anti-tumor therapy)). 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 19 Oct 2026.
