A randomized study to assess the efficacy, safety, and tolerability of BIIB080 in patients with mild cognitive impairment due to Alzheimer's disease or mild dementia in Alzheimer's patients
Résumé de l'étude
This is a randomized, double-blind, placebo-controlled Phase II study that includes a double-blind, placebo-controlled treatment period and a follow-up period. Approximately 735 participants will be selected to receive one of 4 possible treatments for about 72 weeks. Selection is done via an interactive response system that determines your disease stage. This response system (Interactive Response Technology, IRT) is also used to ensure that during the later random allocation of patients, approximately equal numbers of participants with Alzheimer's disease (AD)-related mild cognitive impairment (MCI) or mild Alzheimer's dementia are included. Furthermore, it will be ensured that approximately 10% of the total participants included in the study are younger than 60 years. Neither your study doctor nor you will know whether you are receiving the drug BIIB080 or an inactive control drug (placebo) during the treatment. This is called “double-blind” and is intended to ensure that later evaluations are free from any influencing prior knowledge.

Intervention étudiée
This study investigates the following treatments:
60 mg Q24W (treatment once every 24 weeks with a dose of 60 mg of BIIB080)
115 mg Q24W (treatment once every 24 weeks with a dose of 115 mg of BIIB080)
115 mg Q12W (treatment once every 12 weeks with a dose of 115 mg of BIIB080)
Placebo Q12W (treatment once every 12 weeks with control substance, without BIIB080)
The drug or control substance is administered intrathecally, meaning it is injected directly into the cerebrospinal fluid (CSF) in the lumbar region via a lumbar puncture.
During the study, up to 12 outpatient visits (3 visits during the screening period, 8 visits during the placebo-controlled treatment period, and 1 visit during the follow-up period) and 14 follow-up phone calls will occur.
All outpatient visits should be conducted ± 7 days around the visit date. Follow-up phone calls occur approximately 48 hours after each dose, approximately 6 weeks after each dose, and once during the follow-up period.
To improve recruitment efficiency, a visit conducted by phone or by a local care service may occur prior to screening to allow for the pre-identification of participants who are most likely to meet the study's inclusion criteria.

Maladie en cours d'investigation
This study investigates the effect of BIIB080 on mild cognitive impairment (MCI) due to Alzheimer's disease or mild Alzheimer's dementia. Beta-amyloid-containing extracellular plaques are a well-known hallmark of Alzheimer's disease. Pathological tau protein, which aggregates into abnormal bundles, is another hallmark of Alzheimer's disease. The “tau pathology” is directly related to the loss of brain cells and cognitive abilities. Previous non-clinical studies with so-called antisense oligonucleotides (ASOs) have shown that specifically designed ASOs can reverse tau deposition and loss of cognitive abilities. ASOs are short-chain, synthetically produced nucleic acids that, in the case of the study drug BIIB0880, block the formation of tau protein.
