FABHALTA Sales Forecast, and Market Size Analysis - 2034

Key Factors Driving FABHALTA Growth

1. First-in-Class Oral Complement Factor B Inhibitor

Fabhalta inhibits complement factor B, blocking activation of the alternative complement pathway upstream of C5 inhibitors. This provides broader control of complement-mediated disease processes.

• The therapy is oral, offering a major convenience advantage compared with injectable complement inhibitors such as eculizumab and ravulizumab.
• Clinical studies demonstrated significant hemoglobin improvements in PNH patients, including those switching from anti-C5 therapies.
• In the APPULSE-PNH study, patients switching to Fabhalta experienced average hemoglobin increases of ~2.01 g/dL, with no transfusions or breakthrough hemolysis reported.

This strong clinical differentiation is expected to drive physician adoption and switching from older complement inhibitors.

2. Expansion Into IgA Nephropathy (Large Untapped Market)

Fabhalta's approval in IgA nephropathy (IgAN) represents one of the largest drivers of future growth.

• The drug received FDA accelerated approval in 2024 for reduction of proteinuria in IgAN.
• Phase III APPLAUSE-IgAN trial results showed Fabhalta significantly slowed kidney function decline and reduced proteinuria by ~38% versus placebo.
• IgAN is a progressive autoimmune kidney disease where up to 50% of patients may progress to kidney failure within 10-20 years.

Because current therapies are limited, Fabhalta is positioned as a disease-modifying targeted therapy, significantly expanding its addressable patient population.

3. Expansion Into Additional Rare Kidney Diseases

Novartis is expanding Fabhalta into additional complement-mediated kidney diseases.

One major opportunity is:

• C3 Glomerulopathy (C3G) - a rare disease with no approved therapies historically.
• In the Phase III APPEAR-C3G study, Fabhalta reduced proteinuria by 35.1% vs placebo at six months.

The European Medicines Agency's CHMP has recommended approval for this indication, which would further broaden the drug's commercial potential.

4. Large Addressable Market in Complement-Mediated Diseases

Complement-driven diseases represent a rapidly expanding therapeutic area.

Key opportunity areas for Fabhalta include:

• Paroxysmal nocturnal hemoglobinuria (PNH)
• IgA nephropathy
• C3 glomerulopathy
• Other complement-mediated renal disorders

The IgA nephropathy market alone was valued at ~$1.2 billion in 2024 and is projected to reach ~$2.8 billion by 2033, creating significant revenue opportunities for Fabhalta.

Because Fabhalta targets the **complement pathway-a central disease driver in several conditions-it could potentially expand into additional autoimmune and renal indications.

5. Strong Early Launch Performance

Fabhalta's commercial launch is gaining traction.

• Novartis reported $57 million in sales during the early global launch phase in 2024.
• Uptake is supported by strong physician interest due to the oral administration and improved clinical outcomes compared with existing therapies.

FABHALTA Recent Developments

• In March 2025, Novartis announced that oral FABHALTA (iptacopan) received US Food and Drug Administration (FDA) approval for the treatment of adults with C3 glomerulopathy (C3G), to reduce proteinuria, making it the first and only treatment approved for this condition.

FABHALTA Drug Summary

FABHALTA (iptacopan) is an oral complement factor B inhibitor developed by Novartis, indicated for the treatment of adults with paroxysmal nocturnal hemoglobinuria (PNH) as monotherapy to control hemolytic anemia by targeting the alternative complement pathway upstream of C3 and C5, thereby addressing both intravascular and extravascular hemolysis, with clinical data showing hemoglobin improvements, LDH reductions over 60%, and fatigue relief compared to anti-C5 therapies. It is also approved to reduce proteinuria in adults with primary immunoglobulin A nephropathy (IgAN) at risk of rapid progression and in adults with complement 3 glomerulopathy (C3G), often in combination with renin-angiotensin system inhibitors, based on significant proteinuria decreases though continued approval for IgAN may depend on confirmatory kidney function studies. Administered as 200 mg capsules twice daily with food, it carries boxed warnings for serious infections from encapsulated bacteria, requiring prior vaccinations, antibiotic prophylaxis, and enrollment in a REMS program. The report provides FABHALTA's sales, growth barriers and drivers, post usage and approvals in multiple indications.
