Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Diagnosis of probable Alzheimer's disease (NIA-AA criteria)
  • Mini-Mental State Examination (MMSE) score 12-24
  • Availability of a study partner who knows the patient well and is willing to accompany the subject to all trial visits, to participate in questionnaires and to complete daily journal assessments

Exclusion Criteria:

  • Pregnancy or unwilling to use adequate birth control method for duration of and 6 months beyond study participation
  • Positive for Hepatitis B, Hepatitis C or HIV at screening
  • Any other condition or situation that the investigator believes may interfere with the safety of the subject or the intent and conduct of the study

  • Related to medical history:

    • Stroke
    • Anaphylaxis
    • Prior adverse reaction to any human blood product
    • Any history of a blood coagulation disorder or hypercoagulability
    • Congestive heart failure
    • Uncontrolled hypertension
    • Renal failure
    • Prior intolerance to intravenous fluids
    • Recent history of uncontrolled atrial fibrillation
    • IgA deficiency (by history)

  • Related to medications or other treatments:

    • Any concurrent use of an anticoagulant therapy. Antiplatelet drugs (e.g., aspirin or clopidogrel) are acceptable
    • Initiation or change in the dosage of a cholinesterase inhibitor or memantine during the trial. A participant already on a cholinesterase inhibitor or memantine must be on a stable dose for at least one month prior to Screening
    • Concurrent participation in another treatment trial for Alzheimer's disease. If there was prior participation, the last dose of the investigational agent must have been at least 6 months prior to Screening
    • Treatment with any human blood product, including intravenous immunoglobulin, during the 6 months prior to Screening or during the trial
    • Concurrent daily treatment with benzodiazepines, typical or atypical antipsychotics, long-acting opioids, or other medications that, in the investigator's opinion, interfere with cognition. Intermittent treatment with short-acting benzodiazepines or atypical antipsychotics may be permitted, provided that no dose is administered within the 72 hours preceding any cognitive assessment

  • Related to magnetic resonance imaging:

    • Claustrophobia
    • Any metallic surgical implant, like a pacemaker or clip that is incompatible with 3T MRI.

Certain metallic implants like joint replacements may be permitted, provided that specific manufacturer specifications are available and that the device is known to be safe for 3T MRI.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Number of participants with adverse events as a measure of safety and tolerability, and number of subjects who comply with the research protocol as a measure of feasibility.
Time Frame: 9 weeks
9 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Change on the 13-item ADAS-Cog
Time Frame: 9 weeks
9 weeks
Change on the Trail-Making Test
Time Frame: 9 weeks

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Time Frame
Change in functional connectivity in the default mode network as assessed by resting state functional MRI
Time Frame: 9 weeks

Compositional assessment of plasma using in vitro analytical methods. The goal is to assess plasma components that might be associated with aging and/or Alzheimer's disease
Time Frame: 9 weeks
9 weeks
In vivo assessment of plasma samples to determine their potential histological effects on the hippocampus and their potential behavioral effects in animal models of cognition
Time Frame: 9 weeks

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
