gliomasPCV Only in 1p/19q Codeleted Anaplastic Gliomas (POLCA)

January 21, 2026 updated by: Assistance Publique - Hôpitaux de Paris

A Randomized Trial of Delayed Radiotherapy in Patients With Newly Diagnosed 1p/19q Codeleted Anaplastic Oligodendroglial Tumors: the POLCA Trial.

Patients with 1p/19q-codeleted anaplastic gliomas treated with RT + PCV are at risk of neurocognitive deterioration. Treating these patients with PCV alone (could reduce the risk of neurocognitive deterioration without impairing overall survival.

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.

Multicentric, Randomized phase III study (1:1), Population: newly diagnosed 1p/19-codeleted anaplastic gliomas, Primary objective: To determine whether treating newly diagnosed 1p/19q-codeleted anaplastic gliomas with PCV alone can increase overall survival without neurocognitive deterioration Control group: radiotherapy followed by 6 cycles of PCV chemotherapy. Experimental group: 6 cycles of PCV chemotherapy (radiotherapy being deferred at the time of progression).

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 and older (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.
Outcome Measure
Measure Description
Time Frame
Survival without neurocognitive deterioration
Time Frame: 9 years
Survival without neurocognitive deterioration (whatever the cause of deterioration, i.e toxicity or tumor progression) defined as the time from study registration to failure in any of the 6 cognitive domains that will be explored (i.e memory, working memory, language, visuo-spatial ability, cognitive executive functions, behavioral executive functions) or death due to any cause, whichever occurs first.
9 years

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
Time Frame
progression free survival
Time Frame: 9 years

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
