• The Paroxysmal Nocturnal Hemoglobinuria market is projected to grow significantly by 2036.

Paroxysmal Nocturnal Hemoglobinuria Market and Epidemiology Analysis

• The United States accounted for the highest Paroxysmal Nocturnal Hemoglobinuria Market Size among the 7MM around 85% of the total market size.
• The total diagnosed prevalent cases of PNH in the 7MM were ~ 12,000 in 2025. These cases are expected to increase during the forecast period (2026-2036).
• Paroxysmal Nocturnal Hemoglobinuria is a rare nonmalignant clonal hematological disorder that is characterized by a deficiency of the GPI-linked complement regulators on the membrane of hematopoietic cells, which renders them susceptible to complement-mediated damage.
• Formerly, Paroxysmal Nocturnal Hemoglobinuria Diagnosis relied on Ham and sucrose tests, now replaced by flow cytometry (FCM) detecting GPI-anchored protein anomalies using monoclonal antibodies or FLAER. FLAER is suitable for nucleated cells but not red blood cells due to glycophorin interference. Also, the lack of international guidelines for proper screening and diagnosis leads to treatment delays.
• Historically, Paroxysmal Nocturnal Hemoglobinuria Treatment was exclusively supportive, and the median survival of patients was 15-20 years, thrombosis being the major cause of death. Supportive measures included corticosteroids during hemolytic attacks, androgen therapy, and red blood cell transfusions for the treatment of anemia, as well as anticoagulant therapy to treat/prevent thrombotic events. However, the use of these palliative measures was not evidence-based, their effectiveness was limited, and they were not devoid of adverse events. Allogeneic HSC transplant was and continues to be, indeed, the only curative Paroxysmal Nocturnal Hemoglobinuria Treatment, but it is reserved for young patients with concurrent bone marrow failure because of transplant-related morbidity and mortality.
• Eculizumab, the first developed complement factor inhibitor, Complement C5 Inhibitors, blocking the terminal complement cascade. Given the benefits of the complement inhibition strategy, changing the natural history of this disease, several novel Paroxysmal Nocturnal Hemoglobinuria Drugs against C5 (terminal inhibitors) or factors upstream C5 (proximal inhibitors) have been developed with the aim of further improving the Paroxysmal Nocturnal Hemoglobinuria Treatment.
• The disease-modifying therapeutic strategy for PNH includes complement inhibition therapy, with Paroxysmal Nocturnal Hemoglobinuria Drugs like SOLIRIS, ULTOMIRIS, and EMPAVELI approved by the FDA, and considered the gold standard. However, safety concerns are associated with eculizumab and ravulizumab, including the risk of meningococcal infections and the persistence of extravascular hemolysis in some individuals treated with eculizumab.

Key Factors Driving the Paroxysmal Nocturnal Hemoglobinuria (PNH) Market

Rising prevalence of PNH

The total diagnosed prevalent cases of PNH in the 7MM were ~ 12,000 in 2025. These cases are expected to increase during the forecast period (2026-2036).

Current treatment in the PNH Market

The introduction of complement inhibitors transformed PNH care. SOLIRIS (eculizumab, Alexion/AstraZeneca) was the first therapy, followed by ULTOMIRIS (ravulizumab, AstraZeneca), offering longer dosing intervals. Supportive measures such as transfusions and anticoagulation remain adjuncts.

PNH competitive landscape

Pipeline activity is robust, with oral complement inhibitors like danicopan (AstraZeneca), iptacopan (Novartis), and crovalimab (Roche) leading the way. Other targets include proximal inhibitors (factor B/D blockade) and gene therapy approaches aimed at long-term disease modification.

Paroxysmal Nocturnal Hemoglobinuria Disease Understanding

Paroxysmal Nocturnal Hemoglobinuria is a rare acquired disorder that affects the pluripotent hematopoietic stem cells, which can impact erythrocytes, leukocytes, thrombocytes, and potentially some endothelial cells. This condition arises from a somatic mutation in the X-linked PIG-A gene, which is involved in synthesizing the glycosylphosphatidylinositol (GPI) anchor required for attaching certain proteins to the cell membrane.

The mutation leads to a deficiency in the GPI anchor, resulting in the underexpression of crucial proteins, such as the complement regulatory proteins 'decay-accelerating factor' (DAF or CD55) and 'membrane inhibitor of reactive lysis' (MIRL or CD59), on the surface of the hematopoietic stem cells and the cells derived from them. This deficiency makes red blood cells more susceptible to attack by the complement system, causing complement-mediated intravascular hemolysis. As a consequence, free hemoglobin levels in the plasma increase, which binds to nitric oxide, leading to its depletion.

Paroxysmal Nocturnal Hemoglobinuria Diagnosis

PNH diagnosis was formerly comforted by in vitro complement activation by either acidity (Ham test) or osmolarity (sucrose test). These tests are obsolete as diagnosing PNH by flow cytometry (FCM) refers to detecting a pathognomonic anomaly. GPI-anchored proteins can be detected after labeling the cells with monoclonal antibodies (for example, anti-CD55 or anti-CD59) or a reagent known as fluorescein-tagged proaerolysin (FLAER), which binds to the glycan portion of the GPI anchor. FLAER is best used on nucleated cells; it does not stain red blood cells, as red blood cells express high glycophorin levels, a protein that binds to aerolysin and interferes with the assay.

Paroxysmal Nocturnal Hemoglobinuria Treatment

Treatment with a C5 inhibitor is the standard for patients with PNH. Eculizumab (SOLIRIS, Alexion Pharmaceuticals) and ravulizumab (ULTOMIRIS, Alexion Pharmaceuticals) are humanized monoclonal antibodies that block terminal complement activation at C5 and inhibit the formation of C5a and C5b. Eculizumab was approved by the US FDA in 2007, and ravulizumab in 2018. These agents bind to the same C5 epitope and have the same mechanism of action; ravulizumab was engineered from eculizumab to have a longer half-life. Both drugs are administered via IV infusion. Pegcetacoplan, the first C3 inhibitor for the Paroxysmal Nocturnal Hemoglobinuria Treatment, was also recently approved by the FDA and EMA.
