Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: Patients with newly diagnosed primary CNS lymphoma

Who may be able to join

  • Subjects capable of giving informed consent, or if appropriate, if subject's capacity is deemed limited due to CNS involvement, a consultee can provide consent on their behalf. Some patients with PCNSL may be incapable of providing their own consent due to the neurological effects of their disease. In these cases the patient will be classed as an incapacitated adult and a legal representative will be sought in accordance with English or Scottish law as applicable (see 7.2.1)
  • A radiological or histological diagnosis of primary CNS lymphoma.
  • Have not received prior CNS directed therapy. Prior use of steroids is permitted.
  • Participants aged ≥18 years old.

Who cannot join

  • Involvement of lymphoma outside of the CNS

About this study

Official title: A Prospective Imaging and Translational Tissue Study in CNS Lymphoma to Enable Further Disease Characterisation and the Development of Potential Predictive and Prognostic Biomarkers

A prospective imaging and translational tissue study in CNS lymphoma to enable further disease characterisation and the development of potential predictive and prognostic biomarkers.

Read the detailed description

As a single centre exploratory study, this trial will recruit patients with newly diagnosed primary CNS lymphoma and will look at the molecular aspects of the disease in the tissue collection and imaging response assessments using CCA with respect to progression free survival.

What is being measured

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

  1. Plasma ctDNA detection

    To assess if plasma ctDNA detection measured from end of treatment (using the tumour informed approach) can be used an early detection tool for progressive disease.

    Measured: 5 Years

  2. Contrast clearance analysis

    To assess the results of contrast clearance analysis

    Measured: 5 Years

Secondary outcomes (5)
  1. Plasma ctDNA detection from end of treatment

    To assess if plasma ctDNA detection measured from end of treatment (using the tumour agnostic approach) can be used as an early detection tool for progressive disease

    Measured: 5 Years

  2. Plasma ctDNA detection rate at baseline

    To assess plasma ctDNA detection rate at baseline using the (i) tumour agnostic and (ii) tumour informed approach

    Measured: 5 Years

  3. Plasma ctDNA detection at end of treatment

    To assess whether plasma ctDNA detection at end of treatment can be used an early detection tool for progressive disease and survival using the (i) tumour agnostic and (ii) tumour informed approach

    Measured: 5 Years

  4. Plasma ctDNA detection rate at disease progression

    To assess plasma ctDNA detection rate at disease progression using the (i) tumour agnostic and (ii) tumour informed approach

    Measured: 5 Years

  5. Radiological data provided by CCA

    To evaluate whether additional radiological data provided by CCA is useful for prognostication and is associated with disease progression and survival

    Measured: 5 Years

Questions about this trial

What is this clinical trial studying?

An observational study of CNS Lymphoma, run by Royal Marsden NHS Foundation Trust at 1 site in United Kingdom.

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 4 inclusion and 1 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 11 Jun 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 United Kingdom. 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 GI and Lymphoma Unit (02086426011, GI.Trials@rmh.nhs.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma ctDNA detection (time frame: 5 Years). 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 11 Jun 2025.
