About this study

Official title: A Phase II Clinical Trial of of Early Application of Memantine and Pioglitazone to Protect Cognitive Function After Radiotherapy

This clinical trial aims to evaluate the efficacy of early intervention with Memantine and Pioglitazone in preventing Radiation-Induced Brain Injury (RIBI) in patients undergoing cranial radiotherapy.

RIBI, a significant complication of radiation therapy for primary and metastatic brain tumors, as well as head and neck cancers, often presents with delayed and irreversible neurological damage, severely affecting patients' quality of life.

Our previous studies have indicated that Memantine, an NMDAR antagonist, and Pioglitazone, a PPAR-γ agonist, play crucial roles in modulating the neuroprotective immune microenvironment by targeting key mechanisms of neuron-astrocyte fatty acid metabolism coupling. These findings suggest that early administration of these drugs could protect cognitive function and reduce neuroinflammation in patients post-radiation.

This prospective phase II clinical trial will assess the combined efficacy of Memantine and Pioglitazone in improving cognitive outcomes and preventing RIBI without adversely impacting the anti-tumor efficacy of radiation therapy. The study will also explore the synergistic effects of these two FDA-approved drugs in early-stage RIBI prevention, providing a new therapeutic strategy for enhancing the quality of life in cancer patients receiving radiotherapy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Memantine Oral TabletDrug

    Also called pioglitazone, hippocampal avoidance whole-brain radiotherapy (HA-WBRT)

    Oral administration of Memantine Tablets (10mg/tablet):

    Week 1: 5mg in the morning. Week 2: 5mg twice daily. Week 3: 10mg in the morning, 5mg in the evening. Weeks 4-24: 10mg twice daily.

  • Pioglitazone 15mgDrug

    Simultaneous oral administration of Pioglitazone Tablets (15mg/tablet):

    Weeks 1-24: 30mg once daily.

  • Hippocampal avoidance whole-brain radiotherapy (HA-WBRT)Radiation

    Based on the RTOG 0933 protocol, hippocampal and perihippocampal regions are delineated, and hippocampal dose constraints are applied. The radiation dose to the perihippocampal region is determined based on the size, number, and volume of brain metastases (whole-brain radiation therapy: DT 30Gy/10F, weeks 1-2; with a simultaneous boost to the pathological local area if necessary, 10-20Gy).

What is being measured

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

  1. the cumulative incidence of cognitive failure

    the proportion of participants who experience cognitive impairments after radiation therapy

    Measured: At weeks 4, 8, 16, 24, 36, and 48 after the completion of radiotherapy

Secondary outcomes (3)
  1. Cognitive Score Decline

    based on the Reliable Change Index of at least one cognitive test

    Measured: At weeks 4, 8, 16, 24, 36, and 48 after the completion of radiotherapy

  2. Progressive-free survival for Intracranial Tumors

    latencies to the first intracranial treatment failure or death from any cause

    Measured: At weeks 4, 8, 16, 24, 36, and 48 after the completion of radiotherapy

  3. Overall Survival

    death due to any cause

    Measured: At weeks 4, 8, 16, 24, 36, and 48 after the completion of radiotherapy

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Memantine Oral Tablet, Pioglitazone 15mg and Hippocampal avoidance whole-brain radiotherapy (HA-WBRT) in people with Radiation Disease and Cognitive Impairment, run by Affiliated Cancer Hospital & Institute of Guangzhou Medical University.

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 8 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: opening soon, as of the sponsor's last update on 19 Sep 2024. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

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?

the cumulative incidence of cognitive failure (time frame: At weeks 4, 8, 16, 24, 36, and 48 after the completion of radiotherapy). 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 19 Sep 2024.
