How does gantenerumab work?

Gantenerumab preferentially interacts with aggregated brain Aβ, both parenchymal and vascular. The antibody elicits phagocytosis of human Aβ deposits in AD brain slices co-cultured with human macrophages. It also neutralizes oligomeric Aβ42-mediated inhibitory effects on long-term potentiation in rat brains.

Is gantenerumab FDA approved?

The U.S. Food and Drug Administration (FDA) has granted breakthrough therapy status to gantenerumab, a human antibody that’s expected to slow or even prevent cognitive decline and memory loss in Alzheimer’s disease.

What is the mechanism of action for aducanumab?

Mechanism of Action Aduhelm (aducanumab-avwa) is a human, immunoglobulin gamma 1 (IgG1) monoclonal antibody directed against aggregated soluble and insoluble forms of amyloid beta. The accumulation of amyloid beta plaques in the brain is a defining pathophysiological feature of Alzheimer’s disease.

What are the side effects of aducanumab?

What are the possible side effects of aducanumab? The most common side effects include areas of brain swelling, small brain bleeding, headache, or falls. The areas of brain swelling and small brain bleeding are usually temporary and resolve over time.

When will BAN2401 be available?

The trial is set to run until 2024. In February 2020, the Alzheimer’s Therapeutic Research Institute announced that the Alzheimer’s Clinical Trial Consortium (ACTC) would conduct a large BAN2401 study co-funded by the NIH and Eisai (press release).

What is amyloid related imaging abnormalities?

Amyloid-related imaging abnormalities (ARIA) are abnormal differences seen in magnetic resonance imaging of the brain of Alzheimer’s disease patients, associated with amyloid-modifying therapies, particularly human monoclonal antibodies such as aducanumab.

What is the target of aducanumab?

Aducanumab (BIIB037) is a human antibody that selectively targets aggregated forms of Aβ, including soluble oligomers and insoluble fibrils.

How long is aducanumab infusion?

The length of each infusion appointment varies from 1 to 3 hours. Aducanumab must be administered over the long term (at least a year). Aducanumab will also require evaluations for the presence of amyloid protein and the severity of Alzheimer’s disease, as well as new types of monitoring during treatment.

What type of drug is aducanumab?

Aducanumab is a monoclonal antibody (a protein that helps your immune system target other proteins), and it is designed to help your body remove something called amyloid beta from the brain. Amyloid beta is an important protein involved in the progression of Alzheimer’s disease.

Who would benefit from aducanumab?

Aducanumab was most helpful in patients with mild impairment due to Alzheimer’s disease. There are many causes of cognitive impairment and patients with cognitive impairment due to other causes, like vascular dementia for example, will not benefit from this treatment.

Is BAN2401 the same as Aducanumab?

Aducanumab and gantenerumab partially target oligomers, while mostly clearing insoluble amyloid plaques; BAN2401 preferentially targets soluble protofibrils (large oligomers) over plaques; and ALZ-801 blocks the formation of oligomers without binding to plaques.

How is BAN2401 administered?

BAN2401-G000-201 Core study is an 18-month study in which 3 dose levels (2.5, 5, and 10 mg/kg) are given biweekly (once every 2 weeks) to separate groups of participants and 2 dose levels (5 and 10 mg/kg) are given monthly (once every 4 weeks) to separate groups of participants.

How many patients are in Gantenerumab Phase 1 trials?

Four Phase 1 trials conducted internationally in a total of 308 patients have tested the safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple doses of infused and subcutaneous gantenerumab in healthy controls and people with Alzheimer’s disease, respectively.

When does the Gantenerumab open label extension study start?

Based on this biomarker data, DIAN-TU and Roche invited participants from all arms of this trial to an open-label extension with high-dose gantenerumab (1,020 mg monthly) for up to three years; this study started in the fall of 2020. Peer-reviewed results were published ( Jun 2021 news ).

How does Gantenerumab work in the human brain?

Gantenerumab preferentially interacts with aggregated brain Aβ, both parenchymal and vascular. The antibody elicits phagocytosis of human Aβ deposits in AD brain slices co-cultured with human macrophages. It also neutralizes oligomeric Aβ42-mediated inhibitory effects on long-term potentiation in rat brains.

How does Gantenerumab work to treat amyloid plaques?

The therapeutic rationale for this antibody is that it acts centrally to disassemble and degrade amyloid plaques by recruiting microglia and activating phagocytosis. Gantenerumab preferentially interacts with aggregated brain Aβ, both parenchymal and vascular.
