How Natalizumab Works

Natalizumab is a monoclonal antibody that targets integrin molecules to prevent immune cells from entering the brain and spinal cord. By doing so, it reduces inflammation and nerve damage associated with MS, helping to decrease relapses and slow disease progression. This makes it an attractive option for patients with active relapsing forms of MS.

Administration and Dosage

Natalizumab is delivered via intravenous infusion every four weeks in a healthcare setting. This regular administration requires patient commitment and monitoring to ensure safety and efficacy. Extended interval dosing may be an option for some, potentially reducing certain risks while maintaining effectiveness.

Risks and Monitoring

A significant risk associated with natalizumab is PML, a rare brain infection. Patients must be regularly screened for JC virus antibodies, which can indicate increased risk of PML. Other side effects can include liver issues and various infections, necessitating ongoing surveillance and management.
