C5 Complement inhibitor Market Summary

• The current C5 complement inhibtor market size is estimated to be approximately USD 4 Billion, in the 7MM.

C5 complement Inhibtor Market and Epidemiology Analysis

• C5 inhibitor exerts its effect by targeting the complement protein C5 and preventing it from splitting into C5a and C5b fragments, which play a major role in the formation of membrane attack complex (MAC). This averts the complement-mediated lysis of RBCs (Intravascular hemolysis), however it fails to stop the extravascular hemolysis.
• Currently, there are five C5 complement inhibitors in the market, approved for various complement dysregulation disorders.
• Alexion’s SOLIRIS (eculizumab) was the first complement inhibitor approved in 2007 for Paroxysmal Nocturnal Hemoglobinuria (PNH). It was later approved for additional three indications namely, Atypical Hemolytic Uremic Syndrome (aHUS), Neuromyelitis Optica Spectrum Disorder (NMOSD), and Generalized Myasthenia Gravis (gMG).
• In addition to SOLIRIS and ULTOMIRIS, the market for C5 complement inhibitors includes Astellas' IZERVAY (avacincaptad pegol), which is approved for geographic atrophy, Regeneron's VEOPOZ (Pozelimab), approved for Chaple disease, and UCB Pharma's ZILBRYSQ (zilucoplan), approved for generalized myasthenia gravis.
• A few of the potential emerging C5 complement inhibitors are crovalimab, nomacopan (C5/LTB4 inhibitor), CAN-106 (C5 inhibitor), and KP104 (C5 and Factor H).
• In July 2022, FDA granted Orphan Drug Designation (ODD) to KP104 for the treatment of PNH.

C5 Complement Inhibitors Market: Understanding and Treatment Algorithm

C5 Complement Inhibitors Overview

C5 is the initiator of the effector terminal phase of the complement system and shares the molecular structure consisting of two chains—α and β, linked by disulfide bonds, with C3 complement inhibitor and C4 complement inhibitor, with the only difference being that C5 does not contain an internal thio-ester bond. The terminal phase is similar for the classical, lectin, and alternative pathways. The incorporation of C3b in the C3 convertases results in the formation of the C5 convertases: C3bBbC3b for the AP and C4bC2aC3b for the CP and LP. These C5 convertases cleave C5 into C5a and C5b, ultimately resulting in the formation of the multimeric MAC.  

Further details related to complement dysregulation disorders are provided in the report

C5 Complement Inhibitors Treatment

SOLIRIS (eculizumab) and ULTOMIRIS (ravulizumab) are some of the few terminal complement inhibitors that block the activity of C5, preventing the formation of the C5b-9 terminal complement complex. These agents inhibit intravascular hemolysis mediated by the terminal complement in patients with complement dysregulation disorders. Despite demonstrated benefits in various complement-mediated diseases, use of inhibitors targeting the classical/lectin and terminal pathways is associated with limitations. Some patients with PNH remain anemic and still require transfusions despite treatment with a C5 or C3 inhibitor.

Marketed C5 Complement Inhibitors Drugs

Currently, there are five marketed C5 complement inhibitors in various indications. 

ZILBRYSQ (zilucoplan) - UCB Pharma

Zilucoplan is a once-daily, subcutaneous, self-administered peptide inhibitor of complement component 5 (C5 inhibitor). As the only once-daily gMG target therapy for self-administration by adult patients with anti-AChR antibody-positive gMG, zilucoplan inhibits complement-mediated damage to the neuromuscular junction through its targeted mechanism of action. The drug received FDA approval in October 2023.

Moroever, in September 2023, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) issued a positive opinion recommending granting marketing authorization for zilucoplan in the European Union (EU) as an add-on to standard therapy for the treatment of generalized myasthenia gravis (gMG) and was later granted marketing authorization by EMA in December 2023. Also in the same year, Japanese Ministry of Health, Labour and Welfare (MHLW) approved zilucoplan for the treatment of gMG in adult patients who inadequately respond to steroids or other immunosuppressants.

Emerging C5 Complement Inhibitors Drugs

Crovalimab:  Genentech

Crovalimab is an investigational, novel anti-C5 recycling monoclonal antibody designed to block the complement system. Crovalimab works by binding to C5, blocking the last step of the complement cascade and is also recycled within the bloodstream, enabling rapid and sustained complement inhibition. Crovalimab’s recycling properties also enable low dose subcutaneous (SC) administration every four weeks. In addition, crovalimab binds to a different C5 binding site from current treatments, which has the potential to provide a treatment option for people with specific C5 gene mutations who do not respond to current therapies. It is also being evaluated in atypical hemolytic uremic syndrome, sickle cell disease, and other complement mediated diseases

In September 2023, FDA accepted the Biologics License Application (BLA) for crovalimab, for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). If approved, crovalimab will be the first monthly subcutaneous treatment for PNH, with the option to self-administer outside of a supervised healthcare setting

C5 Complement Inhibitors Market Outlook 

The C5 complement inhibitors market is poised for substantial growth in the upcoming years. Following the introduction of SOLIRIS and ULTOMIRIS, there has been considerable momentum in the complement inhibitor market. Numerous companies are currently in the process of developing innovative complement inhibitors with the aim of matching the efficacy and safety standards set by eculizumab.

Since the PNH and aHUS has already been crowded with a lot of marketed and emerging drugs. The companies have now shifted their focus to other complement dysregulation disorders, including but not limited to C3G, IgA-N, and Geographic Atrophy.

Besides major players, small pharma companies are currently assessing innovative C5 inhibitors for a range of complement-mediated disorders, with an aim to offer more convenient routes of administration or target multiple proteins simultaneously. For example, Genentech's crovalimab provides subcutaneous delivery, whereas Akari Therapeutics' nomacopan inhibits both C5 and LTB4.
