PIASKY (crovalimab-akkz) is a complement C5 inhibitor indicated for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). The medication is approved for use in adult and pediatric patients 13 years of age and older. To receive this treatment, patients must have a body weight of at least 40 kg.
How PIASKY Works
Crovalimab-akkz is a monoclonal antibody that binds with high affinity to the complement protein C5. This binding inhibits the cleavage of C5 into C5a and C5b, which prevents the formation of the membrane attack complex (MAC). By blocking this process, the drug inhibits terminal complement-mediated intravascular hemolysis in patients with PNH.

PIASKY Boxed Warning
SERIOUS MENINGOCOCCAL INFECTIONS PIASKY, a complement inhibitor, increases the risk of serious infections caused by Neisseria meningitidis [see Warnings and Precautions (5.1) ] . Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early. Complete or update vaccination for meningococcal bacteria (for serogroups A, C, W, Y, and B) at least 2 week...
WARNING: SERIOUS MENINGOCOCCAL INFECTIONS PIASKY, a complement inhibitor, increases the risk of serious infections caused by Neisseria meningitidis [see Warnings and Precautions (5.1) ] . Life-threatening and fatal meningococcal infections have occurred in patients treated with complement inhibitors. These infections may become rapidly life-threatening or fatal if not recognized and treated early. Complete or update vaccination for meningococcal bacteria (for serogroups A, C, W, Y, and B) at least 2 weeks prior to the first dose of PIASKY, unless the risks of delaying therapy with PIASKY outweigh the risk of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients receiving a complement inhibitor. See Warnings and Precautions (5.1) for additional guidance on the management of the risk of serious infections caused by meningococcal bacteria. Patients receiving PIASKY are at increased risk for invasive disease caused by N. meningitidis , even if they develop antibodies following vaccination. Monitor patients for early signs of serious meningococcal infections and evaluate immediately if infection is suspected. Because of the risk of serious meningococcal infections, PIASKY is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called PIASKY REMS [see Warnings and Precautions (5.2) ] . WARNING: SERIOUS MENINGOCOCCAL INFECTIONS See full prescribing information for complete boxed warning. PIASKY increases the risk of serious and life-threatening infections caused by Neisseria meningitidis . Complete or update meningococcal vaccination at least 2 weeks prior to the first dose of PIASKY, unless the risks of delaying PIASKY outweigh the risks of developing a serious infection. Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for meningococcal vaccination in patients rec
PIASKY Target & Pathway
ProTarget
A cascade of proteins that enhances immune responses and directly attacks pathogens. Uncontrolled complement activation causes tissue damage in diseases like paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome.
