Crovalimab, sold under the brand name Piasky, is a monoclonal antibody used for the treatment of people with paroxysmal nocturnal hemoglobinuria. [1] It is a complement component 5 (C5) inhibitor. [1] [5]
Crovalimab was approved for use in China in February 2024, [6] in Japan in April 2024, [7] in the United States in June 2024 and in the European Union in August 2024. [3] [4] [2] It was developed and is marketed by Roche/Genentech.
In the US, crovalimab is indicated for the treatment of people aged 13 years of age and older with paroxysmal nocturnal hemoglobinura and body weight of at least 40 kilograms (88 lb). [1] [8]
The US FDA label for crovalimab contains a boxed warning about the increased risk of Neisseria meningitidis infection, which can be life-threatening. A recent meningococcal vaccination is strongly advised. [1]
Three phase III clinical trials have evaluated crovalimab in both people who were C5 inhibitor–naive and those switching to crovalimab from other C5 inhibitors. [9]
COMMODORE 1 [10] is a phase III randomized clinical trial comparing crovalimab vs eculizumab in people with paroxysmal nocturnal hemoglobinuria treated with C5 inhibitors. [11] COMMODORE 1 examines the safety, tolerability and pharmacokinetic/pharmacodynamic properties of crovalimab in PNH patients switching from eculizumab. The study showed that crovalimab maintained disease control in PNH patients switching from eculizumab. [11] [12]
COMMODORE 2 [13] is a phase III randomized trial comparing crovalimab vs eculizumab in people with paroxysmal nocturnal hemoglobinuria who are naive to C5 inhibitor treatment. [14] COMMODORE 2 was positive for its co-primary endpoints, transfusion avoidance and hemolysis control (measured lactate dehydrogenase levels) which are disease control indicators, and its data shows crovalimab is non-inferior to eculizumab. [15] [14] [16] [17]
COMMODORE 3 [18] is a phase III single-arm trial run in China, studying crovalimab in C5 inhibitor-naive people with paroxysmal nocturnal hemoglobinuria. [19] COMMODORE 3 assessed the safety, efficacy, pharmacokinetics, and pharmacodynamics of crovalimab in people with C5-naive paroxysmal nocturnal hemoglobinuria. The study met the co-primary efficacy endpoints of haemolysis control and transfusion avoidance. [19] [20]
Crovalimab was approved for use in China in February 2024, [6] and in Japan in April 2024. [7] [21]
Crovalimab was approved for medical use in the United States in June 2024. [2] [8]
In June 2024, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Piasky, intended as monotherapy for the treatment of people twelve years of age or older with a weight of 40 kilograms (88 lb) and above with paroxysmal nocturnal haemoglobinuria. [3] [22] The applicant for this medicinal product is Roche Registration GmbH. [3] Crovalimab was approved for medical use in the European Union in August 2024. [3] [4]
Crovalimab is the international nonproprietary name. [23]
Crovalimab is the subject of five phase III studies for paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome (aHUS). It is also being investigated for the treatment of sickle cell disease and other conditions. [24]
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, life-threatening disease of the blood characterized by destruction of red blood cells by the complement system, a part of the body's innate immune system. This destructive process occurs due to deficiency of the red blood cell surface protein DAF, which normally inhibits such immune reactions. Since the complement cascade attacks the red blood cells within the blood vessels of the circulatory system, the red blood cell destruction (hemolysis) is considered an intravascular hemolytic anemia. There is ongoing research into other key features of the disease, such as the high incidence of venous blood clot formation. Research suggests that PNH thrombosis is caused by both the absence of GPI-anchored complement regulatory proteins on PNH platelets and the excessive consumption of nitric oxide (NO).
Factor D is a protein which in humans is encoded by the CFD gene. Factor D is involved in the alternative complement pathway of the complement system where it cleaves factor B.
Eculizumab, sold under the brand name Soliris among others, is a recombinant humanized monoclonal antibody used to treat paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, generalized myasthenia gravis, and neuromyelitis optica. In people with paroxysmal nocturnal hemoglobinuria, it reduces both the destruction of red blood cells and need for blood transfusion, but does not appear to affect the risk of death. Eculizumab was the first medication approved for each of its uses, and its approval was granted based on small trials. It is given by intravenous infusion. It is a humanized monoclonal antibody functioning as a terminal complement inhibitor. It binds to the complement C5 protein and inhibits activation of the complement system, a part of the body's immune system. This binding prevents the breakdown of red blood cells in the bloodstream in people with paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome.
Maribavir, sold under the brand name Livtencity, is an antiviral medication that is used to treat post-transplant cytomegalovirus (CMV). Maribavir is a cytomegalovirus pUL97 kinase inhibitor that works by preventing the activity of human cytomegalovirus enzyme pUL97, thus blocking virus replication.

Riociguat, sold under the brand name Adempas, is a medication by Bayer that is a stimulator of soluble guanylate cyclase (sGC). It is used to treat two forms of pulmonary hypertension (PH): chronic thromboembolic pulmonary hypertension (CTEPH) and pulmonary arterial hypertension (PAH). Riociguat constitutes the first drug of the class of sGC stimulators. The drug has a half-life of 12 hours and will decrease dyspnea associated with pulmonary arterial hypertension.
Remimazolam, sold under the brand name Byfavo, is a medication for the induction and maintenance of procedural sedation in adults for invasive diagnostic or surgical procedures lasting 30 minutes or less. It is a benzodiazepine drug, developed by PAION AG in collaboration with several regional licensees as an alternative to the short-acting imidazobenzodiazepine midazolam, for use in the induction of anesthesia and conscious sedation for minor invasive procedures. Remimazolam was found to have both a more rapid onset and a shorter duration than midazolam, and human clinical trials showed a faster recovery time and predictable, consistent pharmacokinetics, suggesting some advantages over existing drugs for these applications.
Olokizumab (OKZ) sold under the name Artlegia, is an immunosuppressive drug, used for the treatment of rheumatoid arthritis and COVID-19. It is a humanized monoclonal antibody against the interleukin-6 (IL-6). IL-6 is a cytokine that plays an important role in immune response and is implicated in the pathogenesis of many diseases. Olokizumab is the first interleukin-6 (IL-6) inhibitor approved for treatment of rheumatoid arthritis which blocks directly cytokine instead of its receptor. Olokizumab specifically binds to IL-6 at Site 3, blocking IL-6 ability to form hexameric complex. Olokizumab was developed by R-Pharm group, and was launched in 2020.
Gemigliptin (rINN), sold under the brand name Zemiglo, is an oral anti-hyperglycemic agent of the dipeptidyl peptidase-4 inhibitor class of drugs. Glucose lowering effects of DPP-4 inhibitors are mainly mediated by GLP-1 and gastric inhibitory polypeptide (GIP) incretin hormones which are inactivated by DPP-4.

The sucrose lysis test is a diagnostic laboratory test used for diagnosing paroxysmal nocturnal hemoglobinuria (PNH), as well as for hypoplastic anemias and any hemolytic anemia with an unclear cause. The test works by using sucrose, which creates a low ionic strength environment that allows complement to bind to red blood cells. In individuals with PNH, some red blood cells are especially vulnerable to lysis caused by complement. The test may also produce suspicious results in other hematologic conditions, including megaloblastic anemia and autoimmune hemolytic anemia. False-negative results can occur when complement activity is absent in the serum. A simpler alternative called the sugar water test also involves mixing blood with sugar and observing for hemolysis, using the same principle as the sucrose lysis test.
Danicopan, sold under the brand name Voydeya, is a medication used for the treatment of paroxysmal nocturnal hemoglobinuria. It is a complement inhibitor which reversibly binds to factor D to prevent alternative pathway-mediated hemolysis and deposition of complement C3 proteins on red blood cells.
