NCT01451749

Brief Summary

The purpose of this phase III study is to further evaluate the effects of shenwu capsule, a traditional Chinese herbal medicine, on cognition, function and memory in patients with amnestic mild cognitive impairment (MCI) who are at greater risk for developing Alzheimer's disease, in a 6-month supervised protocol of a traditional Chinese herbal medicine. The results of this study may provide support for a relatively simple and inexpensive treatment strategy with herbal therapy that specifically targets individuals with the mild cognitive impairment that directly influence risk of developing dementia for older adults.

Outcome Measures

Primary Outcomes (1)

  • Change in Cognitive Scores: Alzheimer Disease Assessment Scale-cognitive. Subscale (ADAS-cog)

    Cognition was assessed with the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) , at baseline (day 1 clinic visit) and at 12-week intervals thereafter until week 24. The ADAS-cog was designed specifically to evaluate the severity of cognitive dysfunctions characteristic of AD patients and includes 11 items. Among these items, memory, orientation, language function, practical ability, and attention are evaluated. The score on the ADAS-cog range from 0 to 70 point, with 0 point indicating no impairment and 70 points indicating severe impairment of cognition. In the Shenwu capsule group, the ADAS-cog score is ranges 3-38.3 points, and 3.3-30.7 points in the Donepezil group. The Change in cognitive scores was calculated as24 week minus the baseline.

    baseline and 24 weeks

Secondary Outcomes (2)

  • Change in Memory Scores: The Delayed Story Recall (DSR) Test From the Adult Memory and Information Processing Battery (AMIPB)

    Baseline and 24 weeks

  • Change in Functional Scores: Instrumental Activities of Daily Living (IADL).

    Baseline to weeks 24

Eligibility Criteria

Age55 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Chinese-speaking adults at least 55 to 80 years of age old, weighting between 45 to 90 kilograms, living in the community.
  • diagnosed with amnestic MCI at screening: (1) memory complaint, corroborated by an informant; (2) abnormal memory function, as screened by the WMS-R Logical Memory II Delayed Story Recall subtest score \<10.4 for age; (3) normal general cognitive function, as determined by a clinician's judgment based on a structured interview with the patients (MMSE of 24 to 30 score for education ); (4) no or minimal impairment in activities of daily living, as determined by a clinical interview with the patient and informant (IADL \<16 score); and (5) not sufficiently impaired, cognitively and functionally, to meet NINCDS-ADRDA criteria for AD, as judged by an experienced AD research clinician. In addition, they were judged to be at stage 2-3 of the GDS, and to have a score of ≤12 of the HAMD for 17 items, of ≤4 on the HIS, and no or minimal medial temporal atrophy (MTA) or hippocampal volume atrophy on the MRI scan.
  • The subjects required adequate vision and hearing to participate in study assessments. Patients receiving chronic aspirin therapy for cardio-protection (≤100 mg per day) or stable doses of antidepressants for at least 3 months were also eligible.

You may not qualify if:

  • Significant neurologic disease that might affect cognition, such as a diagnosis of Alzheimer's disease, stroke, Parkinson's disease, multiple sclerosis, or severe head injury with loss of consciousness; a score of MMSE\<24,or any major psychiatric disorder (e.g., DSM-IV-defined psychosis, major depression, bipolar disorder, or alcohol or substance abuse);
  • Recent history of chronic use of NSAIDs or aspirin (\>100 mg per day);
  • History of upper gastrointestinal bleeding that required transfusion or surgery within the previous 3 years,or documented evidence of an active gastric or duodenal ulcer within the previous 3 months,or history of NSAID-associated ulcers;
  • History of active malignancy except for basal cell carcinoma or squamous cell carcinoma of the skin, or prostate cancer, within the preceding 24 months;
  • A chronic or acute renal, hepatic, or metabolic disorder; and uncontrolled hypertension and diabetes mellitus;
  • History of hypersensitivity to the treatment drugs; or concomitant drugs (including anticonvulsant agents, anti-parkinsonian agents, antipsychotics, anxiolytics, hypnotic agents, neuroleptic agents, cholinomimetic agents, vitamin E, or ginkgo biloba extract or any other drugs including traditional Chinese herbal medicines which can affect memory); or participants in other clinical studies within the past 30 days.

Limitations and Caveats

First, there was no placebo group. As all subjects knew that they were being treated with one of two drugs, and all of the individuals who assessed the patients knew this as well, the results may have been influenced by a positive response bias.
