About this study

Official title: PROTONBIOMARKS - Research of Biomarkers of Response to Proton Beam Therapy in Pediatric and Adult Patients: A Genomic, Epigenetic, and Immunological Analysis

This trial is a paucicentric, clinico-biological cohort study with retrospective and prospective enrollment, aiming to identify biomarkers predictive of response to Proton Beam Therapy (PBT) in cancer patients (high grade sarcoma, brain tumors and meningioma). This study include collection of clinical data, of tumor samples (collected during standard of care) and a blood sample for alive patients.

Read the detailed description

The proton beam model policy adopted by the American Society of Radiation Oncology (ASTRO) in 2017 supports proton therapy in primary solid neoplasms in children treated with curative intent. To date, PBT is also recognised in adults as a valid option providing life expectancy > 10 years, for inoperable axial or head and neck sarcomas, low grade brain tumors (i.e. low grade astrocytoma, oligodendroglioma and ependymoma), non-operated meningioma of skull base and other rare clinical situations (re-irradiation, locally aggressive tumor malignant or not arising in sites which preclude R0 or R1 surgical resection). Recently, Jhaveri et al. have reported the retrospective analysis of a National Cancer Data Base (NCDB) and shown an improved overall survival in adult Grade I-IV glioma patients treated with PBT versus patients treated with radiotherapy (XRT). Positive impact on toxicity free survival and general health status of patients were reported in others indications. centers join their expertise (pediatric, brain and sarcoma cancers for Centre Léon Bérard (CLB) and protons for CAL) and their recruitment to optimize the treatment strategy for these patients.

The Centre Leon Bérard recently reported on the ProfilER protocol (NCT01774409). It is the largest molecular characterization program in France with now over 4000 patients included. It enabled to identify genomic biomarkers of radio resistance. In this context, the investigator's proposal is to conduct a genomic, epigenetic, and immunological analysis of patients treated with proton beam therapy with the aim to identify Biomarkers of response to PBT in pediatric and adult patients.

What is being measured

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

  1. Identify predictive biomarkers for local response at 6 months after the end of Proton Beam Therapy

    Correlation between local tumor response according to RECIST 1.1 criteria and expression of biomarkers defined by using different techniques (HTG, WES, RNAseq, IHC)

    Measured: At 6 months after the end of Proton Beam Therapy

Secondary outcomes (4)
  1. To identify predictive biomarkers for clinical outcomes

    Correlation between local tumor response according to RECIST 1.1 criteria and expression of biomarkers defined by using different techniques (HTG, WES, RNAseq, IHC)

    Measured: At 12 months and at 24 months after the end of Proton Beam Therapy

  2. To identify predictive biomarkers for clinical outcomes

    Correlation between progression free survival and expression of biomarkers expression of biomarkers defined by using different techniques (HTG, WES, RNAseq, IHC)

    Measured: From the start of Proton Beam Therapy until the date of the first documented progression or date of death from any cause, whichever came first, assessed up to 48 months

  3. To identify predictive biomarkers for clinical outcomes

    Correlation between overall survival and expression of biomarkers defined by using different techniques (HTG, WES, RNAseq, IHC)

    Measured: From the start of Proton Beam Therapy until the date of death from any cause, assessed up to 48 months

  4. To identify predictive biomarkers for clinical outcomes

    Correlation between radiation related toxicity (only Adverse Event (AE) Grade ≥3) according to NCI-CTCAE V5.0. and expression of biomarkers defined by using different techniques (HTG, WES, RNAseq, IHC)

    Measured: From the start of Proton Beam Therapy until at least 24 months after the end of Proton Beam Therapy

Questions about this trial

What is this clinical trial studying?

An observational study of Brain Cancer and Meningioma, run by Centre Leon Berard at 2 sites 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 8 inclusion and 2 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: finished, as of the sponsor's last update on 22 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Identify predictive biomarkers for local response at 6 months after the end of Proton Beam Therapy (time frame: At 6 months after the end of Proton Beam Therapy). 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 22 Apr 2026.
