Blood Biomarker Signature in Glioma

July 4, 2025 updated by: Cancer Trials Ireland

Are Gliomas in Adults Associated With a Unique Identifying Blood Biomarker Signature?

This is an exploratory, translational and non-interventional clinical study. The aim of this study is to identify a blood biomarker signature for glioma.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The identification of biomarkers (proteins, peptides and micro RNAs (miRNAs)) in the serum of patients with glioma would be a new, less invasive approach, which could help in the diagnosis of a glioma, and potentially help guide therapeutic decisions.

The investigators will investigate the existence of biomarker profiles, which can

  • distinguish between low and high grade gliomas
  • correlate with patient outcomes including response to treatment and survival
  • indicate progression from a low to a high grade glioma.

In this study the investigators collect and analyse blood samples taken from patients with suspected newly diagnosed grade II/III glioma or glioblastoma multiforme (GBM). Blood samples will be collected before any surgical intervention (resection or biopsy) and at various follow-up time points until progression or death. Based on the known natural history of gliomas (described above), it is planned to follow patients with grade III/IV tumours, who receive treatment, for up to 3 years and those with grade II-III tumours, (irrespective of treatment) for up to 5 years. Ultimately, the investigators envisage the translation of our observations into the hospital setting to aid the distinction between glioma grade II and grade III/IV.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

All patients with suspected newly diagnosed glioma with planned surgical intervention will be eligible.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Translational, observational study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Identification of protein and miRNA biomarker ignatures
Time Frame: 5 years

Identification of protein and miRNA biomarker signatures in serum of glioma patients as assessed by surface-enhanced laser desorption ionization - time of flight (SELDI-TOF), Isobaric tags for relative and absolute quantitation (iTRAQ) and miRNA array technologies.

Profiling experiments will be performed on the serum samples

  • to find unique glioma associated serum biomarkers
  • to determine if the levels of discovered biomarkers accurately reflect glioma grade.
  • to investigate if alterations in levels of glioma associated markers predict glioma progression from low grade to high grade Profiling patient's protein and miRNA biomarker signatures will allow association of expression patterns with tumour grade. We will determine if alterations in levels of identified serum biomarkers correlate with disease progression and patient outcome, including tumour response, time to progression (TTP) and overall survival (OS).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Correlation with disease progression
Time Frame: 5 years
The secondary objectives are to determine if alterations in levels of identified serum biomarkers correlate with disease progression and patient outcome, including tumour response, time to progression (TTP) and overall survival (OS).
