E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
• To assess the safety and tolerability of up to 7 repeated injections of CAD106 with Alum or MF59 in patients with mild Alzheimer’s Disease (AD) over 90 weeks. • To compare the immunogenicity of CAD106 with Alum vs MF59 after up to 7 injections in patients with mild Alzheimer’s Disease (AD) as measured by the titers of Aβ-specific IgG in serum across regimens and in reference to non-adjuvanted CAD106. |
|
E.2.2 | Secondary objectives of the trial |
• To characterize the Aβ- and Qβ-specific antibody response to CAD106 (with Alum or MF59) in serum and CSF, e.g. by measuring Aβ-specific IgMs and Qβ-specific IgGs in serum, and markers of the quality of the immune response. • To characterize Aβ-specific and Qβ-specific T-cell response to CAD106 (with Alum or MF59) using PBMCs. • To evaluate changes over time of the concentrations of disease related markers (Aβ1-40 and Aβ1-42 in plasma; Aβ1-40, Aβ1-42, total-tau, phospho-tau in CSF, or other markers) in patients with mild AD receiving CAD106 (with Alum or MF59) compared to placebo. |

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Participation in the pharmacogenetics and blood pharmacogenomics study is optional and consent from the patient will be documented in a separate Informed Consent.
For further details, please refer to Section 6.7 "Pharmacogenetics and Pharmacogenomics"of the enclosed protocol. |
|
E.3 | Principal inclusion criteria |
1. Written informed consent obtained before any assessment is performed according to local requirements for obtaining consent in mild AD patients. 2. Male and female patients below the age of 85 years. 3. Female patients must be without childbearing potential (post-menopausal or surgically sterilized). 4. Diagnosis of dementia of the Alzheimer’s type according to the DSM-IV criteria. 5. Patients who satisfy the criteria for a clinical diagnosis of probable AD. 6. Mild AD as confirmed by a MMSE score of 20 to 26 (both inclusive) at screening, and either untreated or on stable dose of cholinesterase inhibitor and/or other AD treatment over the last 4 weeks prior to the clinical assessments. 7. Sufficient education to have been able to read, write, and communicate effectively during the pre-morbid state. 8. Cooperative, willing to complete all aspects and attend all visits of the study including lumbar puncture/CSF samplings (primarily for safety reasons), and capable of doing so, either alone or with the aid of a responsible caregiver. 9. Residing with someone in the community throughout the study or, if living alone, who have daily contact with a primary caregiver. 10. Primary caregiver is present and willing to assent in writing to taking the responsibility for assessing the condition of the patient throughout the study, and for providing input to safety and tolerability assessments in accordance with all protocol requirements.
For a detailed description of the Inclusion Criteria, please refer to Section 4.1 of the enclosed protocol. |
|
E.4 | Principal exclusion criteria |
Exclusion criteria related to CNS: 1. Any medical or neurological condition, other than AD, that contributes significantly to the patient’s dementia, including any CSF and/or brain MRI findings at screening. 2. History in the past two years or current diagnosis of CNS inflammation. 3. Evidence of vascular dementia or other cerebrovascular disease, assessed by investigator and/or MRI central reader. 4. Current DSM-IV diagnosis of major depression and/or any other DSM-IV Axis 1 diagnosis that may interfere with the evaluation of the patient’s response to study medication, including other primary neurodegenerative dementia, schizophrenia, or bipolar disorder. 5. History or current diagnosis of seizure disorder.
Exclusion criteria related to other medical conditions: 6. Any advanced, severe, progressive, or unstable disease that may interfere with the safety, tolerability and pharmacodynamic assessments and/or with the antibody titer response in the study or put the patient at special risk 7. History or current diagnosis of an active autoimmune disease. 8. Evidence of systemic inflammation. 9. Coronary heart disease. 10. Symptomatic heart failure fulfilling the criteria of New York Heart Association (NYHA) Category > II or known left ventricular dysfunction with left ventricular ejection fraction <45%, or any other severe or unstable cardiovascular disease. 11. Vital signs outside of the following ranges at screening and baseline evaluations. 12. A QTc value greater or equal to 500 msec on the screening electrocardiogram as assessed by the central ECG reader using either Bazett or Fredericia formula, whichever the highest. 13. History of malignancy of any organ system, treated or untreated, within the past 5 years whether or not there is evidence of local recurrence or metastases.
For a detailed description of the Exclusion Criteria, please refer to Section 4.2 of the enclosed protocol. |
