Combination Treatment Study for Memory Impairment and Depression
NCT01658228 · View on ClinicalTrials.gov ↗
Study Summary
Patients presenting with depression (DEP) and cognitive impairment (CI), represent a unique, understudied population that is difficult to diagnose, treat and estimate prognosis. Our pilot data, supported by the literature, suggest that many DEP-CI patients show cognitive decline and often convert to dementia, primarily Alzheimer's disease (AD). In DEP-CI, there is a lack of data on treatment response of mood symptoms to antidepressant treatment and particularly of cognitive deficits to cognitive enhancer treatment. Our initial pilot data in a double-blind study showed that donepezil was superior to placebo in improving memory in antidepressant-treated DEP-CI patients. In a second pilot study, open label es-citalopram plus memantine treatment led to a low rate of conversion to dementia. In this proposed pilot clinical trial, the investigators will evaluate, treat and follow a broad sample of 80 DEP-CI patients at NYSPI/Columbia University Medical Center (N = 40) and Duke University Medical Center (N = 40). Recruitment will be from clinics and/or advertisements. In the treatment protocol, all 80 DEP-CI patients will receive baseline mood and memory assessments and open antidepressant treatment with citalopram for 8 weeks. At 8 weeks, repeat assessment will occur and patients whose depression has responded to citalopram will be randomized to add-on donepezil or placebo. Non-responders to citalopram will receive open treatment with venlafaxine and will be randomized 8 weeks later (16 weeks of open antidepressant treatment) to add-on donepezil or placebo. Patients will be followed for a total period of 18 months with continuous open antidepressant treatment during the trial. Donepezil is being studied in order to increase the likelihood of obtaining a signal. If the results are positive, the investigators can begin clarifying the mechanism(s) in subsequent trials.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01658228
The ClinicalTrials.gov registry entry for NCT01658228 describes a study currently listed as completed. It is categorized as Phase 4, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 86 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is New York State Psychiatric Institute, which has 117 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Depression appearing as the primary indexed condition, and to 4 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01658228 reports 2 study locations spanning 2 distinct geographic areas — top geographies include New York, North Carolina. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
