Study summary

This is a randomized, controlled, double-blind, multicenter Phase 3 clinical study to assess the efficacy and safety of envafolimab plus platinum-based doublet chemotherapy versus placebo plus platinum-based doublet chemotherapy as neoadjuvant/adjuvant therapy in subjects with resectable stage IIIA and IIIB (N2) NSCLC. Primary study endpoints are MPR rate assessed by BIPR and EFS assessed by BIRC.

Read the detailed description

A total of approximately 390 participants are planned to be enrolled in this study. After being screened and qualified, the subjects will be randomly assigned to receive Envalfolimab or placebo plus platinum-based doublet chemotherapy in 1:1 ratio for a total of 3-4 cycles of neoadjuvant therapy (determined by the investigator), the feasibility of surgery is evaluated by the investigator within 4-6 weeks after the end of neoadjuvant therapy and surgery will be performed. Envafolimab (experimental group) or placebo (control group) will be administered after surgery. After completion of treatment, subjects will enter a follow-up phase, including safety follow-up, tumor disease follow-up, and survival follow-up.All randomized subjects in this study are required to receive tumor imaging evaluation as scheduled and get continuous safety assessment during the srceening and treatment period.

Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

What researchers measure

Primary outcomes

  1. MPR by BIPR

    MPR rate is defined as the percentage of participants having ≤10% viable tumor cells in the resected primary tumor and all resected lymph nodes following completion of neoadjuvant therapy (evaluated by BIPR)

    Time frame: Up to 5 years

  2. EFS by BIRC

    EFS is defined as the time from randomization until the occurrence of events leading to inoperable disease progression, post-operative disease progression (BIRC assessment based on RECIST 1.1) or recurrence/metastasis, or death from any cause.

    Time frame: Up to 5 years

Secondary outcomes

  1. pCR

    pCR rate is defined as the percentage of participants having an absence of residual invasive cancer in resected lung specimens and lymph nodes following completion of neoadjuvant therapy, assessed by BIPR;

    Time frame: Up to 5 years

  2. DFS

    DFS is defined as the time from post-surgery to radiographic disease progression, local or distant recurrence, or death from any cause, assessed by BIRC;

    Time frame: Up to 5 years

  3. OS

    OS is defined as the time from randomization until death from any cause.;

    Time frame: Up to 5 years

  4. EFS

    EFS is defined as the time from randomization until the occurrence of events leading to inoperable disease progression, post-operative disease progression or recurrence/metastasis, or death from any cause., assessed by investigator;

    Time frame: Up to 5 years

  5. Explore the quality of life for subjects by EORTC QLQ-C30

    All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.

    Time frame: Up to 5 years

  6. Explore the quality of life for subjects by EORTC QLQ-LC13

    All of the scales and single-item measures range in score from 0 to 100. A high score for the scales and single items represents a high level of symptomatology or problems.

    Time frame: Up to 5 years

  7. PD-L1, ctDNA

    To explore the correlation between clinical efficacy and tumor tissue sample biomarkers (such as PD-L1 level, etc.) and blood sample biomarkers (such as ctDNA level, etc.)

    Time frame: Up to 5 years

Started Nov 2023 (actual). Primary completion is estimated for Dec 2027, 49 months after the start.

Of 314 industry-sponsored phase 3 interventional studies under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 27 and three quarters within 57. This study's planned 49 months is above that.

Counting every sponsor, half of 423 studies reached it within 45 months; a quarter within 30 and three quarters within 69.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 25, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
