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 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Description

Inclusion Criteria:

  • Written informed consent signed and dated by the patient and the caregiver.
  • Patients having participated in AFFiRiS 005A and received ≥1 vaccination with AFFITOPE AD03
  • Availability of a partner/caregiver knowing the patient and being able to accompany the patient to the visits and being available for the telephone phone calls

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
Measure Description
Time Frame
Safety/Tolerability
Time Frame: 52 weeks
  • Withdrawal criteria (continuation decision) Number of patients who withdraw due to AEs Reason for withdrawal
  • Number and kind (description) of AEs
  • Number and kind (description) of SAEs
  • Changes from study AFF005A in: Physical and neurological examination/ Concomitant medication/ Vital signs (blood pressure, heart rate, respiratory rate, body temperature)/ Body mass (weight)/ MRI of the brain/ ECG/ Laboratory assessment (haematology, biochemistry, coagulation, serology, APP crossreactivity and urinalysis)
52 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
Measure Description
Time Frame
Clinical Efficacy
Time Frame: 52 weeks

Changes from study AFF005A in:

  • CIBIC plus (Clinician's Interview-Based Impression of Change, + carer interview)

  • CERAD plus (The Consortium to Establish a Registry for AD)
  • Neuropsychiatric inventory
  • Activity of daily living

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 2011

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). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
