What side effects are associated with this type of intervention?

Common treatments for Multiple Sclerosis (MS) include anti-CD20 monoclonal antibodies like Ofatumumab, as well as other disease-modifying therapies (DMTs) such as glatiramer acetate, dimethyl fumarate, and natalizumab. Ofatumumab and similar anti-CD20 therapies can cause side effects such as infusion-related reactions, infections, and potential liver enzyme elevations. Glatiramer acetate may lead to injection site reactions and lipoatrophy. Dimethyl fumarate is associated with gastrointestinal issues and flushing. Natalizumab carries a risk of progressive multifocal leukoencephalopathy (PML), a serious brain infection, especially in patients with prior immunosuppressant use or positive anti-JCV antibodies.

What prior FDA approvals exist?

Ofatumumab is an anti-CD20 monoclonal antibody used in the treatment of Multiple Sclerosis (MS). Similar FDA-approved treatments include Ocrelizumab, another anti-CD20 monoclonal antibody, which has been approved for both relapsing forms of MS and primary progressive MS. These treatments work by targeting and depleting B-cells, which are believed to play a role in the autoimmune response associated with MS. Other FDA-approved treatments for MS include interferon beta formulations, glatiramer acetate, and oral medications like dimethyl fumarate and fingolimod, which have different mechanisms of action aimed at reducing relapse rates and slowing disease progression.

What other types of research exist?

Promising novel alternatives to Ofatumumab for Multiple Sclerosis patients include: 1) Ustekinumab, a monoclonal antibody targeting interleukin-12 and interleukin-23, which has shown potential in immune-mediated disorders. 2) Alemtuzumab, which has demonstrated efficacy in relapsing-remitting MS. 3) Natalizumab, particularly with extended interval dosing to reduce risks. These therapies offer different mechanisms of action and have shown positive outcomes in clinical trials.

Summary

This trial will test if patients with a specific type of multiple sclerosis benefit from switching to a new medication. The medication aims to reduce harmful cells in the nervous system, potentially preventing future issues. It has been approved in several countries for treating this condition.

Who is the study for?

This trial is for adults aged 18-45 with relapsing-remitting multiple sclerosis (RRMS) who haven't had a relapse in the past year and have been on a disease-modifying treatment for at least six months. Participants should be able to attend study visits, use a wearable device, provide blood samples, and have an EDSS score of 0-5.5. Those with other diseases mimicking MS symptoms or active infections like COVID-19 cannot join.

What is being tested?

The study tests if switching to Ofatumumab is beneficial for RRMS patients showing no recent relapses but elevated neurofilament light levels compared to staying on their current therapy. It explores whether this biomarker predicts better outcomes with Ofatumumab.

What are the potential side effects?

Ofatumumab may cause side effects such as infusion reactions, infections due to immune system changes, and possibly allergic responses in those sensitive to its components.

Mechanism Of Action

Other Research

Multiple Sclerosis (MS) treatments primarily aim to modulate the immune system to reduce inflammation and prevent further damage to the nervous system. Ofatumumab, like other anti-CD20 monoclonal antibodies (e.g., Ocrelizumab), targets CD20 proteins on B-cells, leading to their depletion and reducing the immune response that attacks myelin. This is crucial for MS patients as it helps to decrease the frequency of relapses and slow disease progression. Other common treatments include interferon beta, which reduces inflammation and modulates the immune response, and glatiramer acetate, which mimics myelin protein to divert the immune attack away from actual myelin. Dimethyl fumarate works by activating the Nrf2 pathway, providing anti-inflammatory and neuroprotective effects. Understanding these mechanisms helps patients and doctors choose the most appropriate therapy based on the disease's activity and the patient's specific needs.
