Study summary

BioEXALK is a prospective study evaluating the biological characteristics of advanced ALK-rearranged NSCLC treated with next generation TKIs in first line, included in the national EXPLORE ALK cohort (GFPC 03-2019), a non-interventional, national, multi-center cohort of ALK-rearranged NSCLC patients.

BioExALK study will be proposed to every patient included in the Explore ALK GFPC 03-2019 study.

Biological analysis will be performed on tumor tissue at diagnosis and at the time of disease progression when available and on circulating tumor DNA (ctDNA).

For plasma testing, after obtained patient consent, blood samples will be taken and analyzed at the Léon Bérard Center (Lyon).

Biological analysis on tissue obtained at diagnosis and at disease progression will be collected and be sent for centralized analysis to the Rouen University Hospital.

Read the detailed description

BioEXALK is a prospective study evaluating the biological characteristics of advanced ALK-rearranged NSCLC treated with new generation TKIs in first line, included in the national EXPLORE ALK cohort (GFPC 03-2019).

Explore ALK GFPC 03-2019 is a non-interventional, national, multi-center cohort of ALK-rearranged NSCLC patients, whose RCB reference is 2020-A00771-38 and which obtained an approval from the IDF II Ethic Committee on 25/05/2020. Biological analysis will be performed on tissue at diagnosis and at the time of disease progression when available and on circulating tumor DNA (ctDNA) on three timepoints (diagnosis, at first tumor evaluation and at the time of disease progression).

  • Tissue : RNAseq will be performed on tumor biopsy (10 slides of 5 microns) to identify the ALK fusion partner and its variant and associated co-mutations..
  • ctDNA : NGS panel on DNA including a large panel of fusions and mutations will be performed on blood samples (30mL on EDTA or STRECKs tubes) at diagnosis, at the time of the first evaluation and at the time of progression).

For plasma testing, after obtained patient consent, blood samples (35mL on EDTA or STRECKs tubes) at diagnosis, at the first evaluation and at disease progression will be taken.

The ALKis include alectinib and brigatinib as first-line therapy or other drugs with marketing authorizations (lorlatinib, entrectinib) or in early access programs (EAPs).

Liquid biopsies will be analyzed with a NGS panel allowing the identification of ALK fusion partners and resistance mechanisms (mutations, fusions, copy number variations). Samples will be sent for centralized analysis to the Léon Bérard Center (Lyon).

For biological analysis on tissue obtained at diagnosis, the ALK fusion partner and its variant will be identified by RNAseq. Whenever a tissue re-biopsy is performed at the time of disease progression as part of the standard of care management of the patient, the remaining tissue sample will be collected as part of the BioExALK study, so that RNAseq analysis will be performed to look for resistance mechanisms. Tissue samples (10 slides of 5 microns) will be sent for centralized analysis to the Rouen University Hospital.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Stage IIIB/IV NSCLC non eligible to locoregional treatment with curative intent
  • ALK rearrangement confirmed by IHC and/or FISH or NGS according to local methods
  • Patient included in the EXPLORE ALK study
  • Age > or = 18 years
  • Patient treated with new generation ALKi

  • Patient enrolled in the french National Health Insurance program or with a third- party payer

Exclusion criteria

Exclusion Criteria:

  • Patients who do not wish to participate in Bioexalk
  • Patients under guardianship
Terms in these criteria, in plain language(3)

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.

Line of therapy

A line of therapy is one course of treatment, which may combine several drugs. First-line is the first course given; second-line follows when that stops working or is not tolerated.

“Two prior lines” means two courses that count separately under the study’s rules — not simply two drugs. Ask the study team if you are unsure how yours are counted.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

What researchers measure

Primary outcomes

  1. Progression Free Survival (PFS)

    PFS assessed by local review using RECIST v1.1, defined as time from treatment initiation to the first clinical or radiological progression or death from any cause

  1. Overall Survival (OS)

    OS defined as time from treatment initiation to death from any cause.

    Time frame: From date of treatment initiation up to 72 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Sep 2021 (actual). Primary completion is estimated for Jun 2027, 69 months after the start.

Of 343 non-industry interventional studies with no phase under Carcinoma, Non-Small-Cell Lung, half reached primary completion within 52 months of starting (the median), counting those still running; a quarter within 28 and three quarters within 98. This study's planned 69 months is above that.

Counting every sponsor, half of 359 studies reached it within 51 months; a quarter within 26 and three quarters within 97.

How these figures are worked out, and which studies are left out of them.

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 Apr 29, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
