Phase II Studies Of Donepezil And Ginkgo Biloba In Irradiated Brain Tumor

Study Purpose

RATIONALE: Donepezil and EGb761 may be effective in improving neurocognitive function (such as thinking, attention, concentration, and memory) and may improve quality of life in patients who have undergone radiation therapy to the brain. PURPOSE: This phase II trial is studying how well donepezil or EGb761 works in improving neurocognitive function in patients who have undergone radiation therapy for primary brain tumor or brain metastases.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT00070161
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

OBJECTIVES: Primary.

  • - Determine the effect of donepezil or EGb761 on neurocognitive function in patients who underwent radiotherapy for a primary brain tumor or brain metastases at least 6 months before study registration.
Secondary.
  • - Determine the toxicity of these drugs in these patients.
  • - Determine the quality of life of patients treated with these drugs.
  • - Quantify the extent of radiation-induced white matter disease and temporal lobe atrophy in patients treated with these drugs.
OUTLINE: This is an open-label, multicenter study.
  • - Group 1 (closed to accrual 10/09/03): Patients receive oral donepezil once daily for 24 weeks.
  • - Group 2: Patients receive oral EGb761 three times daily for 24 weeks.
In both groups (group 1 closed to accrual 10/09/03), treatment continues in the absence of unacceptable toxicity. In both groups (group 1 closed to accrual 10/09/03), quality of life and neurocognitive assessment is performed at baseline and at weeks 6 (group 1 only), 12, 24, and 30. Patients are followed at 6 weeks. PROJECTED ACCRUAL: A total of 70 patients (35 per treatment group) will be accrued for this study within 9.5 months. (Group 1 closed to accrual 10/09/03)
