FABHALTA Set to Disrupt Complement Inhibitor Market with Oral Convenience and Strong Efficacy | DelveInsight
Iptacopan is an innovative, first-in-class oral small molecule that reversibly inhibits factor B—a crucial serine protease in the alternative pathway of the complement system. By targeting this point upstream of the C5-terminal pathway, iptacopan effectively prevents both intravascular and extravascular hemolysis in adults with paroxysmal nocturnal hemoglobinuria (PNH). Its selective mechanism allows it to modulate alternative pathway dysfunction without compromising the body's defense against infections via other complement pathways, thus lowering the risk of infection.
FABHALTA is the brand name of iptacopan and is prescribed to:
Iptacopan is also being investigated for other complement-mediated diseases, including myasthenia gravis and atypical hemolytic uremic syndrome (aHUS)—all representing areas of high unmet medical need. It may become the first complement pathway inhibitor capable of slowing disease progression in these conditions. Reflecting its promise, iptacopan has received orphan drug designations from both the FDA and EMA for C3G and PNH, along with EMA PRIME status for C3G and EMA orphan designation for IgAN, supported by encouraging Phase II clinical data and disease prevalence.

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, non-cancerous blood disorder caused by a clonal defect, leading to the absence of GPI-anchored complement regulatory proteins on the surface of blood-forming cells. This deficiency makes the cells vulnerable to destruction by the complement system. In 2024, approximately diagnosed prevalent cases of PNH were reported across the 7MM, with the United States accounting for the largest share. The number of cases is expected to grow at a moderate CAGR through 2034.
Treatment for PNH primarily focuses on complement inhibition, with FDA-approved therapies such as serving as the standard of care. However, concerns remain around the safety profiles of eculizumab and ravulizumab. Recently approved agents targeting factor B and D—such as (iptacopan), (danicopan), and (crovalimab)—seek to provide more effective and safer treatment options.
The market size of PNH in the 7MM was more than in 2024. The United States accounted for the largest market share with approximately in 2024 among 7MM. Overall, the PNH treatment landscape is expected to evolve significantly between 2025 and 2034, driven by the introduction of innovative therapies currently in clinical development.

IgA Nephropathy (IgAN) is an autoimmune condition that targets the kidneys, disrupting blood filtration within the small renal blood vessels. This disease is triggered by an abnormal protein that harms the glomeruli—the kidneys' filtering units. DelveInsight estimates that there were approximately prevalent cases of IgAN across the 7MM in 2024. These diagnosed prevalent cases are projected to rise by 2034 at a Traditional treatment approaches primarily involve ACE inhibitors and angiotensin II receptor blockers (ARBs), which help control symptoms such as high blood pressure.
Currently approved therapies for IgAN include (budesonide), (iptacopan), (sparsentan), (atrasentan). The treatment landscape is expected to undergo substantial transformation between 2024 and 2034, driven by the introduction of innovative therapies. According to DelveInsight's analysis, the IgAN market in the 7MM was valued at approximately in 2024. Over the forecast period from 2025 to 2034, this market is projected to grow at a .
Given that targeted treatments for IgA nephropathy were virtually nonexistent until recently—and considering the critical need for options that delay progression to end-stage kidney disease (ESKD)—any major therapeutic advancement is likely to significantly reshape the market during the forecast period.

Emerging PNH therapies include (Omeros), (Regeneron Pharmaceuticals), (NovelMed), and others, reflecting a dynamic evolution in treatment strategies. In , NovelMed announced that the US FDA had granted to , an alternative pathway (AP) blocker anti-Bb antibody, for the treatment of PNH.
The IgA nephropathy pipeline possesses some drugs in early, mid, and late-stage developments to be approved in the near future. The emerging landscape holds a diverse range of therapeutic alternatives for treatment, including (Sibeprenlimab, Zigakibart), (IONIS-FB-LRx/RG6299), (Povetacicept), (ULTOMIRIS), (Atacicept), (Felzartamab, Mezagitamab), (Vemircopan), (Ruxoprubart), (ADX-097), (KP104), (WAL0921), (ARO-C3), and others in different lines of treatment. The expected launch of these therapies shall further create a positive impact on the market.
The emerging pipeline of C3G holds a few significant products in development by prominent key players such as , coming up with interventions such as , respectively.

Discover how FABHALTA is shaping the IgAN treatment landscape @
FABHALTA is a first-in-class oral factor B inhibitor developed by Novartis for the treatment of PNH. Its approval marks a significant shift in the competitive landscape of the PNH market, which has historically been such as from AstraZeneca's Alexion unit. FABHALTA's oral route of administration, coupled with its ability to control both , offers a differentiated clinical profile that addresses some of the key limitations of current therapies, potentially expanding the PNH market and redefining the standard of care.
The market uptake of FABHALTA is expected to be driven by several factors: , improved quality of life due to reduced transfusion dependence, and its favorable efficacy and safety profile. As an oral agent, FABHALTA reduces the burden associated with biweekly or monthly infusions, a critical consideration for patient adherence and long-term disease management. Moreover, its ability to target the a more holistic control of hemolysis, including extravascular components often insufficiently addressed by current C5 inhibitors.
However, FABHALTA's success will be influenced by various market dynamics, including . While Novartis is leveraging its strong global footprint to ensure could pose reimbursement challenges in certain geographies. Additionally, other pipeline agents targeting upstream components of the or offering similar oral convenience may intensify competition, requiring continuous differentiation through real-world evidence and long-term outcomes.
—such as use in other complement-mediated diseases (e.g., C3G, aHUS, IgAN)—could further enhance FABHALTA's commercial potential and market footprint. As the increasingly crowded and sophisticated, Novartis will need to maintain a robust lifecycle management strategy to preserve its competitive edge and maximize market penetration.
