Trial summary

Immunotherapy have revolutionized the field of oncology, but response rates are low and all patients relapse, due to immunologic (myeloid immunosuppressive cells) and non-immunologic (cancer stem- cells (CSC)) mechanisms. Read more about this study

About this study

Official title: Characterization of the Effect of G-CSF on the Interactions Between MDSC and Cancer Stem-cells in Non-small Cell Lung Cancers (CIRCUIT)

Immunotherapy have revolutionized the field of oncology, but response rates are low and all patients relapse, due to immunologic (myeloid immunosuppressive cells) and non-immunologic (cancer stem- cells (CSC)) mechanisms. CSC are able to circulate within blood, protected from destruction by immunosuppressive cells such as MDSC. Some factors such as G-CSF, administered to lower febrile neutropenia, should modulate properties of MDSC and CSC, but data are contradictory, and literature remain poor regarding its effects on the interactions between MDSC and CSC in blood clusters. Indeed, this project aims at better characterizing the effect of G-CSF on these interactions and on their functions in NSCLC patients receiving G-CSF.

Read the detailed description

MDSC, CSC and the clusters in blood from NSCLC patients will be assessed to evaluate the impact of G-CSF on their phenotype and functions. Samples from 2 groups of NSCLC patients receiving chemotherapy and immunotherapy will be used: 15 receiving concomitant G-CSF, and 15 not receiving concomitant G-CSF

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Phenotype of MDSC and CSC

    Expression of different MDSC markers corresponding to the rate of the different MDSC subpopulations

    Measured: At baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months and 24 months (end of chemo-immunotherapy) or in case of relapse

  2. Functions of MDSC and CSC

    Immunosuppressive and non immunosuppressive functions of the different populations of MDSC

    Measured: At baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months and 24 months (end of chemo-immunotherapy) or in case of relapse

Questions about this trial

What is this clinical trial studying?

A study testing Blood sample in people with Non Small Cell Lung Cancer and Immunotherapy, run by University Hospital, Bordeaux at 1 site in France.

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 5 inclusion and 13 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 30 Jul 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 France. 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.

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 Charlotte DOMBLIDES (+33556795808, charlotte.domblides@chu-bordeaux.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phenotype of MDSC and CSC (time frame: At baseline, 3 weeks, 6 weeks, 12 weeks, 6 months, 12 months and 24 months (end of chemo-immunotherapy) or in case of relapse). The study lists 2 primary outcomes in all. 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 30 Jul 2025.
