Study summary

The goal of this clinical trial is to learn if the treatment by systemic Brigatinib (ALUNBRIG®) associated to local ablative therapy (LAT) treatment is improved if administered when the brigatinib works best in participants presenting an advanced non-small cells lung cancer with an ALK gene anomaly (this anomaly produces a defective protein that is responsible for the multiplication of cancer cells).

This clinical trial is expected to involve 45 participants in several sites in France.

Advanced non-small cell lung cancer (NSCLC) participants with ALK rearrangements treated with brigatinib in first line of non-curable setting will be screened.

If the disease assessment done between 3 to 9 months after initiation of brigatinib shows:

  • a tumor response or stabilization (according to RECIST 1.1)
  • a disease which meets the definition of an oligometastatic disease (five metastatic lesions or less and a maximum of two lesions per organ)
  • all tumor targets are accessible to a local ablative therapy (confirmed by an expert panel of clinicians before inclusion): surgery, stereotactic radiosurgery (SRS). For liver, adrenal, or other metastases, percutaneous thermal ablation will be accepted.

Participants will be asked to visit the clinic:

  • for eligibility criteria assessment prior to LAT
  • for LAT
  • every 8 weeks for checkups and tests the first year after LAT
  • and then every 12 weeks, for a maximum period of 3 years.

Eligible patients will benefit from local ablative therapy with continuation of brigatinib.

Terms in these criteria, in plain language(21)

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.

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.

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.

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.

Metastases

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

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.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Interventions

  • BiologicalBlood samples for Hematology

    Complete blood count will include erythrocytes, neutrophils, eosinophils, basophils, lymphocytes, monocytes, platelets, leukocytes, hemoglobin, hematocrit.

  • BiologicalBlood samples for Chemistry

    Clinical chemistry will include serum electrolytes (sodium, potassium, calcium, corrected calcium for hypoalbuminemia), creatinine, CrCl with local formula, and fasting blood glucose.

  • BiologicalBlood sample for liver function tests

    Laboratory tests to assess liver function will include Aminotransferase Alanine (ALAT), Aminotransferase Aspartate (ASAT), Phosphatase Alkaline (ALP), Gamma-glutamyl Transferase (GGT), total and conjugated bilirubin.

  • BiologicalPregnancy test

    Pregnancy test will be performed in women of childbearing potential, including women who have had a tubal ligation. Childbearing potential is defined as not having undergone surgical sterilization, hysterectomy, and/or bilateral oophorectomy or not being postmenopausal (≥12 months of amenorrhea). Urine pregnancy tests will be based on the measurement of β-Human Chorionic Gonadotropin (HCG). If a urine pregnancy test is positive, it must be confirmed by a serum pregnancy test. Urine pregnancy tests will be performed at screening.

  • ProcedureTumour assessment

    Tumor assessment according to the RECIST v1.1 include the following radiological evaluation: thoracic CT scan, brain MRI or CT scan (MRI is preferred), abdominopelvic scan, PET-CT scan mandatory and at the Investigator's discretion, if needed bone scintigraphy and chest X-ray.

What researchers measure

Primary outcomes

  1. Progression free survival (PFS) centrally assessed

    PFS is defined as the time from Brigatinib initiation until tumor progression or death from any cause according to RECIST v1.1, evaluated by the expert panel. Radiological evaluation of the target lesions(s) will be performed at the following time points: Screening, then every 8 weeks during the first year then every 12 weeks thereafter. An expert panel of blinded clinicians will anonymously review the radiological evaluations and confirm/infirm the Investigator's assessment. Each Investigator must provide all the documents necessary to assess the various endpoints. Progression occurring before 2 years will be considered for the endpoint. Patients alive without progression will be censored at the last radiological assessment.

    Time frame: From the start date of treatment up to the disease progression as per central reading or for a maximum of 3 years.

Secondary outcomes

  1. Progression free survival (PFS) locally assessed

    PFS is defined as the time from Brigatinib initiation until tumor progression or death from any cause according to RECIST v1.1, evaluated by the investigators. Radiological evaluation of the target lesions(s) will be performed at the following time points: Screening, then every 8 weeks during the first year then every 12 weeks thereafter. If a Computed Tomography (CT) scan for tumor assessment is performed in a Positron Emission Tomography (PET) scanner or CT scanner, the CT acquisition must be consistent with the standards for a full-contrast diagnostic CT scan. Response will be assessed by the Investigator at each center using RECIST v1.1. Assessments should be performed by the same evaluator, if possible, to ensure internal consistency across visits. Progression occurring before 2 years will be considered for the endpoint. Patients alive without progression will be censored at the last radiological assessment.

    Time frame: From the start date of treatment up to the disease progression as per local reading or for a maximum of 3 years.

  2. Overall survival (OS)

    Overall survival defined as the time from Brigatinib initiation until death or lost of follow up. Patients alive will be censored at the date of last news or data cutoff. The patient's status (dead, alive or censored) will be determined at the same time points as PFS (Screening, then every 8 weeks during the first year then every 12 weeks thereafter) in order to evaluate OS. In addition, OS will be determined during the Post-study Follow-up Period via in-person or phone contact every 3 months.

    Time frame: From the start of treatment until death or lost of follow-up or for a maximum of 3 years

  3. Median PFS

    Median PFS defined as the time from Brigatinib initiation until death or lost of follow up. Patients alive without progressive disease will be censored at the date of last news or data cutoff.

    Time frame: From the start of treatment until death or lost of follow-up or for a maximum of 3 years

  4. Safety and tolerability

    Safety and tolerability : proportion of patients with any adverse event (AE), serious AEs (SAEs) and all AEs of grade ≥3 according to the National Cancer Institute (NCI) Common terminology criteria for adverse events (CTCAE) v5.0 criteria. Participants will be monitored for AEs from the time the informed consent form is signed until 90 days after the last administration of radiotherapy or until 60 days after the last surgery / thermal ablation. Safety assessments may include monitoring of any or all of the following parameters: clinical symptoms, laboratory, pathological, radiological or surgical findings, results of physical examination, or results of other tests and/or procedures. Any later SAE, i.e. occurring after the end of the reporting period, which is considered to be related to the trial intervention(s) or to the research (protocol required diagnostic procedures and examinations carried out during the research) must be reported without any limitation in terms of deadline.

    Time frame: From the enrolment of the participant up to until 90 days after the last administration of radiotherapy or until 60 days after the last surgery / thermal ablation

  5. Duration of Treatment (DOR)

    Duration of treatment, defined as the time from the first Brigatinib treatment administration until the date of last treatment administration. Dates of first and last treatment administration will be recorded for each treatment to calculate the duration of treatment.

    Time frame: From the start date of treatment up to stop date of treatment or for a maximum of 3 years

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 Jun 2025 (actual). Primary completion is estimated for Oct 2030, 63 months after the start.

Of 287 non-industry phase 2 interventional studies under Lung Neoplasms, half reached primary completion within 72 months of starting (the median), counting those still running; a quarter within 43 and three quarters within 113. This study's planned 63 months is below that.

Counting every sponsor, half of 364 studies reached it within 65 months; a quarter within 34 and three quarters within 105.

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 ↗
