Comparison of pharmacokinetics, pharmacodynamics, safety, and tolerability of the amyloid β monoclonal antibody solanezumab in Japanese and white patients with mild to moderate alzheimer disease

Objectives: Solanezumab is a humanized anti-amyloid β monoclonal antibody being developed as a passive immunization treatment to slow the progression of Alzheimer disease (AD). Pharmacokinetics (PK), pharmacodynamics, safety, and tolerability after a single dose of solanezumab were compared between Japanese and white patients with AD.; Methods: Japanese and white patients with mild to moderate AD […]

Mechanism of amyloid removal in patients with Alzheimer disease treated with gantenerumab

Background: Gantenerumab is a fully human anti-Aβ monoclonal antibody in clinical development for the treatment of Alzheimer disease (AD).; Objectives: To investigate whether treatment with gantenerumab leads to a measurable reduction in the level of Aβ amyloid in the brain and to elucidate the mechanism of amyloid reduction.; Design: A multicenter, randomized, double-blind, placebo-controlled, ascending-dose […]

Safety, tolerability, and antibody response of active Aβ immunotherapy with CAD106 in patients with Alzheimer’s disease: randomised, double-blind, placebo-controlled, first-in-human study

Background: Immunotherapy targeting the amyloid β (Aβ) peptide is a potential strategy to slow the progression of Alzheimer’s disease. We aimed to assess the safety and tolerability of CAD106, a novel active Aβ immunotherapy for patients with Alzheimer’s disease, designed to induce N-terminal Aβ-specific antibodies without an Aβ-specific T-cell response.; Methods: We did a phase […]

CD4 nadir is a predictor of HIV neurocognitive impairment in the era of combination antiretroviral therapy

Objective: Despite immune recovery in individuals on combination antiretroviral therapy (CART), the frequency of HIV-associated neurocognitive disorders (HANDs) remains high. Immune recovery is typically achieved after initiation of ART from the nadir, or the lowest historical CD4. The present study evaluated the probability of neuropsychological impairment (NPI) and HAND as a function of CD4 nadir […]

Safety and changes in plasma and cerebrospinal fluid amyloid beta after a single administration of an amyloid beta monoclonal antibody in subjects with Alzheimer disease

Objectives: Active and passive immunization strategies have been suggested as possible options for the treatment of Alzheimer disease (AD). LY2062430 (solanezumab) is a humanized monoclonal antibody being studied as a putative disease-modifying treatment of AD.; Methods: Patients with mild to moderate AD were screened and selected for inclusion. Initial screening was performed for 54 subjects, […]

Reduction of aggregated Tau in neuronal processes but not in the cell bodies after Abeta42 immunisation in Alzheimer’s disease

Alzheimer’s disease (AD) pathology is characterised by aggregation in the brain of amyloid-beta (Abeta) peptide and hyperphosphorylated tau (phospho-tau), although how these proteins interact in disease pathogenesis is unclear. Abeta immunisation results in removal of Abeta from the brain but cognitive decline continues to progress, possibly due to persistent phospho-tau. We quantified phospho-tau and Abeta42 […]

A single ascending dose study of bapineuzumab in patients with Alzheimer disease

The safety, tolerability, and pharmacokinetics (PKs) of bapineuzumab (AAB-001), a humanized monoclonal antibody to amyloid beta, were evaluated in patients with mild-to-moderate Alzheimer disease in a phase 1, randomized, third-party unblinded, placebo-controlled, single ascending dose trial. Thirty patients received bapineuzumab infusion of 0.5, 1.5, or 5 mg/kg or placebo (6 active, 2 placebo for 0.5 […]

18-Month study of intravenous immunoglobulin for treatment of mild Alzheimer disease

Intravenous immunoglobulin (IVIg) has been proposed as a potential agent for Alzheimer’s disease (AD) immunotherapy because it contains antibodies against beta-amyloid (Abeta). We carried out an open label dose-ranging study in 8 mild AD patients in which IVIg was added to approved AD therapies for 6 months, discontinued, and then resumed for another 9 months. […]

Long-term follow-up of patients immunized with AN1792: reduced functional decline in antibody responders

Background: Immunization of patients with Alzheimer’s disease (AD) with synthetic amyloid-beta peptide (Abeta(42)) (AN1792) was previously studied in a randomized, double-blind, placebo-controlled phase 2a clinical trial, Study AN1792(QS-21)-201. Treatment was discontinued following reports of encephalitis. One year follow-up revealed that AN1792 antibody responders showed improvements in cognitive measures as assessed by the neuropsychological test battery […]

Autoimmune dementia: clinical course and predictors of immunotherapy response

Objective: To define the diagnostic characteristics and predictors of treatment response in patients with suspected autoimmune dementia.; Patients and Methods: Between January 1, 2002, and January 1, 2009, 72 consecutive patients received immunotherapy for suspected autoimmune dementia. Their baseline clinical, radiologic, and serologic characteristics were reviewed and compared between patients who were responsive to immunotherapy […]
