Primary Chemotherapy by BCNU-TMZ Combination in Newly Diagnosed Anaplastic Oligodendrocytic Tumors: Phase II Trial With Translational Molecular Analysis (TEMOBIC)

May 4, 2026 updated by: Assistance Publique Hopitaux De Marseille

The first-line treatment of anaplastic oligodendrogliomas, radiotherapy exclusive or combined with PCV, will be defined by the pending results of phase III of the EORTC.

If the phase II study proposed here achieves its objective, it may help define a new treatment regimen that will be compared to the standard arm from phase III of the EORTC.

In addition, this study, by prospectively testing the predictive value of 1p and 19q deletions and of REGF amplification, may allow characterization of patients using these markers. If validated, this characterization can constitute a key element in any therapeutic evaluation (patient stratification), and potentially a major tool for medical decision support in these tumors.

Study Overview

Status

Status

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

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.
