About this study

Purpose: This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the therapeutic effects of thalidomide in radiotherapy-related cognitive impairment.

Further study details as provided by Sun Yat-sen Memorial Hospital, Sun Yat-sen University / Yameitang.

Primary outcome measure: cognitive improvement, which is determined by the difference value of ADAS-cog score before and after the treatment of memantine.

Read the detailed description

Application of radiotherapy to patients with head and neck cancer isa mainstay treatment in contemporaryoncology practice. However, patients who received radiation are vulnerable to development of cognitive impairment.There is no acknowledged and effective standard treatment for radiotherapy-related cognitive impairment. We supposed that memantine, as the N-methyl-D-aspartate receptor antagonist, would relieve radiotherapy-related cognitive impairment after head and neck cancer, and would improve the life quality for these patients and their families.

Primary objectives: This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the efficacy of memantineon cognition in radiotherapy-related cognitive impairment.

Secondary objectives:

To evaluate the effect of memantine on sleep disorder, mood disorder, activities of daily living, and safety in patients with radiotherapy-related cognitive impairment.

OUTLINE: This is randomized, double-blind, placebo-controlled clinical trial. Patients will be enrolled and administrated with memantine or placebo. Memantine will be supplied as 10 mg per pill to be taken by mouth. Placebo will be supplied as substitute of 10 mg memantine per pill to be taken by mouth.

Patients will be screened, consented, enrolled and have a washout period for 6 weeks. Then these patients will be randomized to two arms.

Arm І: Patients receive memantine with a dosage of 5 microgram at 8 am daily for one week (Week 1), then 5 microgram at 8 am and5 microgram at 5 pm for one week (Week 2), then 10 microgram at 8 am and 5 microgram at 5 pm for one week (Week 3), then 10 microgram at 8 am and 10 microgram at 5 pm for 21 weeks (Week 4-24), in the absence of unacceptable toxicity or severe deterioration.

Arm ІI: Patients receive placebo with a dosage of one half pill at 8 am daily for one week (Week 1), then one half pill at 8 am and one half pill at 5 pm for one week (Week 2), then one pill at 8 am and one half pill at 5 pm for one week (Week 3), then one pill at 8 am and one pill at 5 pm for 21 weeks (Week 4-24), in the absence of unacceptable toxicity or severe deterioration.

What is being measured

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

  1. cognitive improvement

    Cognitive improvement is determined by the difference value of ADAS-cog score before and after the treatment of memantine.

    Measured: Baseline to Week 24

Secondary outcomes (5)
  1. improvement of global condition

    Improvement of global condition is determined by the difference values of CIBIC-plus before and after the treatment of memantine.

    Measured: Baseline to Week 24

  2. improvement of activities of daily living

    Improvement of activities of daily living is determined by the difference values of ADL before and after the treatment of memantine.

    Measured: Baseline to Week 24

  3. improvement of activities of daily living

    Improvement of activities of daily living is determined by the difference values of Clinical Dementia Rating before and after the treatment of memantine.

    Measured: Baseline to Week 24

  4. improvement of mental statement

    Improvement of mental statement is determined by the difference values of MMSE before and after the treatment of memantine.

    Measured: Baseline to Week 24

  5. improvement of psychological statement, including sleep disorder, mood disorder, etc.

    Improvement of psychological statement, including sleep disorder, mood disorder, etc. is determined by the difference values of Neuropsychiatric Inventory (NPI) before and after the treatment of memantine.

    Measured: Baseline to Week 24

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Memantine in people with Cognitive Impairment, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.

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 7 inclusion and 11 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: status not confirmed, as of the sponsor's last update on 12 Apr 2019. 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 China. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yamei Tang, Ph.D (86-208-133-2620, yameitang@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

cognitive improvement (time frame: Baseline to Week 24). 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 12 Apr 2019.
