Study population: Clinically staged as IIIB-IV, unresectable locally advanced, recurrent, or metastatic ROS1 fusion positive non small cell lung cancer

Who may be able to join

  • Age ≥ 18 years old;
  • Histologically or cytologically diagnosed as non-small cell lung cancer (NSCLC);
  • Clinically staged as IIIB-IV, unresectable locally advanced, recurrent, or metastatic NSCLC according to the 8th edition of the AJCC Lung Cancer Staging Manual;
  • ROS1 fusion detected in tissue, cytological, or liquid biopsy specimens (such as plasma, cerebrospinal fluid, pleural effusion, or ascites) through molecular testing methods such as FISH, RT-PCR, NGS, etc.;
  • At least one measurable lesion according to RECIST 1.1 criteria;
  • No prior systemic anti-cancer treatment for locally advanced/metastatic disease (such as chemotherapy, targeted therapy, immunotherapy, anti-angiogenic therapy, etc.); patients who have previously received platinum-based adjuvant/neoadjuvant chemo/radiotherapy or radical chemo/radiotherapy for progressive disease are eligible if disease progression occurs more than 6 months after the last treatment;

  • For patients who have progressed on first-line treatment with entrectinib and have tissue specimens or peripheral blood samples before and after treatment with entrectinib, they may participate in this study;
  • For patients who are currently on first-line treatment with entrectinib and have not yet progressed, if they have tissue specimens or peripheral blood samples before treatment with entrectinib and agree to participate in this study and sign an informed consent form to collect tissue specimens or peripheral blood samples at the time of first treatment follow-up progression, they may participate in this study;
  • For newly diagnosed patients who have not yet received any drug treatment, those who need first-line treatment with entrectinib according to the clinical standard of care, after agreeing to participate in this study and signing an informed consent form, will have tissue specimens or peripheral blood samples collected before treatment with entrectinib, followed by routine drug use and treatment follow-up, and additional tissue specimens or peripheral blood samples will be collected at the time of first treatment follow-up progression;
  • Cooperate with the researchers to provide clinical and pathological data, imaging data, biological specimen collection, follow-up, etc., required for the study process, and agree to use the testing data for this study.

Who cannot join

  • Patients with mixed small cell lung cancer components.
  • Carrying other clearly druggable targets, such as EGFR sensitive mutations, EGFR exon 20 insertions, ALK fusions, RET fusions, KRAS activating mutations, BRAF V600E mutations, NTRK1/2/3 fusions, ERBB2 exon 20 insertions, MET exon 14 skipping, MET amplification, etc.
  • Having received prior systemic treatment (such as chemotherapy, targeted therapy, immunotherapy, anti-angiogenic therapy, etc.).
  • Suffering from other malignant tumors within the past 5 years, with the exception of those with very low risks of metastasis or death (5-year RFS rate > 90%, such as early-stage prostate cancer, breast cancer, etc.).
  • Having any contraindications to entrectinib treatment.
  • Being unable to understand the informed consent form, unable to cooperate with sample collection and follow-up, or refusing to sign the informed consent form.

About this study

Official title: A Multi-center Retrospective Study of the Mechanism of Acquired Resistance in First Line Treatment of ROS1fusion Positive NSCLC With Entrectinib

The goal of this observational study is to learn about the mechanism of acquired resistance in first line trearment of ROS1-positive NSCLC with entrectinib. The main question it aims to answer is:

what is the acquired resistant mechanism of entrectinib as first line treatment setting in patients?

Tissue or blood samples of participants who have already taken entrectinib as their regular medical care for NSCLC will send for Next gene sequencing for genomic profiles and bioinformatic analysis.

Being tested
venipuncyure, Entrectinib
Medical subject headings
Carcinoma, Non-Small-Cell Lung

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • venipuncyureProcedure or surgery

    venipuncture as clinical practical setting

  • EntrectinibDrug

    600mg, oral, once daily

What is being measured

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

  1. biomarker profile

    Measured: Analysis will occur when all patient samples have collected. From enrollment to the study completion, an average of 2 year.

Questions about this trial

What is this clinical trial studying?

An observational study of ROS1 Fusion Positive and Non Small Cell Lung Cancer, run by Fudan 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 10 inclusion and 6 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: looking for participants now, as of the sponsor's last update on 30 Sep 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 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.

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 Jialei Wang (18017312369, wangjialei@shca.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

biomarker profile (time frame: Analysis will occur when all patient samples have collected. From enrollment to the study completion, an average of 2 year.). 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 Sep 2025.
