Nineteen imaging centers using 12 different scanner models participate in the aducanumab prodromal trial and send the scan data to a central reading CRO, where a binary classification method and quantitative standardized uptake value ratios (SUVRs) are compared to establish best methods of interpreting an amyloid scan. They then undergo amyloid PET and MRI scans a positive amyloid scan is required for entry.

Prospective participants must score more than 19 on the MMSE, between 0.5 and 1 on the Clinical Dementia Rating, and 27 or lower on the Free and Cued Selective Reminding Test (FCSRT). Besides aducanumab, this trial evaluates the performance of proposed research diagnostic criteria (see Dubois et al., 2010 Albert et al., 2011). In summer 2012, Biogen Idec started PRIME, a multicenter, multiple-dose study in 166 people with prodromal or mild AD. Consistent with preclinical work, the antibody generated no plasma spike. (For comparison, the multiple sclerosis antibody natalizumab is administered as a 300-mg infusion.) BIIB037 exposure changed in a linear fashion across doses, with little variability from person to person. This amounts to 4 grams in a 150-pound person. Because BIIB037 seemed safe at 30 mg/kg, 60 mg/kg was added. In dose-ranging studies, a new dose is given once the safety-monitoring board has deemed the previous dose safe. No new ARIA developed during the trial beyond age- and AD-related baseline ARIA. They were mild or moderate, some possibly related to the study drug but not to the dose. Side effects included headache, diarrhea, and dizziness. Amyloid-related imaging abnormalities (ARIAs) were monitored with four MRI scans, read both locally and by a central reader at an imaging CRO. Participants were assessed at 10 time points up to two years after dosing. FindingsДЄ Phase 1 safety and pharmacokinetics study began with a single-ascending-dose trial of 0.3 mg/kg to 30 mg/kg intravenous BIIB037 in 56 people with mild to moderate AD. Brain-exposure studies in mice suggest that microhemorrhages start at 500 mg/kg, more than 100 times the minimally effective dose for plaque clearance, 3 mg/kgВ ( Apr 2013 conference news).

Thirteen-week chronic dosing in old APP-transgenic mice reduced plaques of all sizes vascular amyloid stayed unchanged. In the brain, BIIB037 preferentially binds parenchymal over vascular amyloid. The rationale was that these donors' immune systems had successfully resisted AlzheimerвЂ™s disease, and that the operative antibodies could be turned into therapeutics by a process called 'reverse translational medicine.' BIIB037 binds aggregated forms of AОІ, not monomer. It was originally derived by the biotech company Neurimmune in Schlieren, Switzerland, from healthy, aged donors who were cognitively normal.

FDA Status: Alzheimer's Disease (Approved) Company: Biogen, Neurimmune BackgroundД«IIB037 is a high-affinity, fully human IgG1 monoclonal antibody against a conformational epitope found on AОІ.
