New Life to an Old Treatment: Pegylated Interferon Beta 1a in the Management of Multiple Sclerosis

Current Medicinal Chemistry
Miguel Angel OrtizElena Urcelay

Abstract

In the 1990s, the beta interferons and glatiramer acetate were introduced for treating relapsing-remitting multiple sclerosis. These medications have a demonstrated record of efficacy and safety, although they require frequent administration via injection and are only partially effective. The optimization of treatment in patients who do not respond adequately to this first-line therapy is essential for attaining the best long-term outcomes. Switching to the recently approved emergent therapies is a strategy to consider for treatment of patients with a suboptimal response. This review summarizes the mechanisms of action, clinical benefits, and safety profiles of current multiple sclerosis disease-modifying therapies, including highly efficacious monoclonal antibodies or convenient oral therapies, and with a special focus on the pegylated interferon beta 1a formulation. We reviewed the recent literature and human clinical trials on multiple sclerosis therapies by bibliographic search in PubMed and clinicaltrials.gov. Although the first-line interferon beta exhibits a favorable benefit-torisk profile, treatment compliance is compromised potentially due to its known adverse events and frequent injectable administration. Less freque...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
