Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

* Homozygous APOE4 genotype.
* Participant willing to have a study partner.

Key
Minimum age
60 Years
Maximum age
75 Years

Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Any disability that prevented the participant from completing all study requirements.
* Current medical or neurological condition that could have impacted cognition or performance on cognitive assessments.
* Advanced, severe progressive or unstable disease that may have interfered with the safety, tolerability and study assessments, or put the participant at special risk.
* History of malignancy of any organ system, treated or untreated, within 60 months prior to screening.
* History of hypersensitivity to any of the investigational drugs or their excipients / adjuvant or to drugs of similar chemical classes.
* Indication or on current treatment with ChEIs and/or another AD treatment (e.g. memantine).
* Contraindication or intolerance to MRI or PET investigations (with fluorinated radio ligands).
* Brain MRI results showing findings unrelated to AD that, in the opinion of the Investigator could have been a leading cause to future cognitive decline, pose a risk to the participant, or prevent a satisfactory MRI assessment for safety monitoring.
* Suicidal Ideation in the past six months or Suicidal Behavior in the past two years, prior to screening.
* A positive drug screen at Screening, if, in the Investigator's opinion, this was due to drug abuse.
* Significantly abnormal laboratory results at Screening, or infection not as a result of a temporary condition.
* Current clinically significant ECG findings. For Cohort - I only: Participants with previous organ transplantation or stem cell transplantation, or indication for treatment with anti-coagulants.

For Cohort - II only: Participants with depigmenting or hypopigmenting conditions (e.g. albinism vitiligo) or active / history of chronic urticarial in the past year.

Summary
Brief summary
The purpose of this study was to test whether two investigational drugs called CAD106 and CNP520, administered separately, could slow down the onset and progression of clinical symptoms associated with Alzheimer's disease (AD) in participants at the risk to develop clinical symptoms based on their age and genotype.
