What Are The Key Driving Factors For The Growth Of The C5 Complement Inhibitors Market?

The increasing prevalence of chronic diseases is expected to propel the growth of the C5 complement inhibitors market going forward. Chronic diseases are long-term medical conditions that progress slowly and persist over time, often requiring continuous medical attention and management to prevent complications. The increasing prevalence of chronic diseases is largely driven by lifestyle changes such as poor diet, physical inactivity, smoking, and stress, which contribute to long-term health deterioration. C5 complement inhibitors help chronic disease patients by blocking the overactivation of the complement system, thereby reducing inflammation, preventing tissue damage, and improving disease outcomes in conditions such as PNH, aHUS, and other complement-mediated disorders. For instance, in October 2022, according to a report published by the World Heart Federation, a Switzerland-based non-profit organization, cardiovascular disease-related deaths are projected to rise from around 22.2 million by 2030, eventually reaching 32.3 million by 2050. Therefore, the increasing prevalence of chronic diseases is driving the growth of the C5 complement inhibitors market.

Emerging Trends And Strategic Opportunities In The C5 Complement Inhibitors Market

Major companies operating in the C5 complement inhibitors market are focusing on developing novel therapies, such as self-administered C5 inhibitors, to expand treatment options for generalized myasthenia gravis. A self-administered C5 inhibitor is a targeted therapeutic agent that blocks the complement C5 protein to reduce inflammation and immune-mediated damage, designed for patient-administered use to treat conditions such as paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome. For instance, in October 2023, Union Chimique Belge (UCB) SA, a Belgium-based biopharmaceutical company, announced Zilbrysq (zilucoplan) for treating adults with generalized myasthenia gravis (gMG) approved by the Food and Drug Administration (FDA), a US-based government regulatory agency. This approval applies specifically to patients who are anti-acetylcholine receptor (AChR) antibody-positive, a common form of the disease. Zilbrysq is a self-administered, once-daily, subcutaneous C5 complement inhibitor, offering a new treatment option for gMG patients. The approval strengthens UCB’s neurology portfolio, expanding treatment choices for individuals with autoimmune neuromuscular disorders.
