Uses
1 INDICATIONS AND USAGE PIASKY is indicated for the treatment of adult and pediatric patients 13 years and older with paroxysmal nocturnal hemoglobinuria (PNH) and body weight of at least 40 kg. PIASKY is a complement C5 inhibitor indicated for the treatment of adult and pediatric patients 13 years and older with paroxysmal nocturnal hemoglobinuria (PNH) and body weight of at least 40 kg ( 1 )
Dosage
2 DOSAGE AND ADMINISTRATION See Full Prescribing Information for instructions on preparation, dosage, and administration. ( 2.2 , 2.3 , 2.4 , 2.5 ) Start with one loading dose administered by intravenous infusion, followed by 4 additional loading doses administered by subcutaneous injection. Then administer a maintenance dose every 4 weeks by subcutaneous injection. For patients switching from another complement inhibitor, the first loading dose of PIASKY should be administered no sooner than the time of the next scheduled complement inhibitor administration. See Full Prescribing Information for considerations when switching from another C5 inhibitor.
Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the label: Serious Meningococcal Infection [see Warnings and Precautions (5.1) ] Type III Hypersensitivity Reactions Related to Drug-Target-Drug Complexes [see Warnings and Precautions (5.3) ] Other Infections [see Warnings and Precautions (5.4) ] Infusion- and Injection-Related Reactions [see Warnings and Precautions (5.5) ] The most common adverse drug reactions (incidence ≥10%) were infusion-related reaction, respiratory tract infection, viral infection, and Type III hypersensitivity reactions.

Interactions
7. DRUG INTERACTIONS PIASKY binds different epitopes on C5 compared to eculizumab and ravulizumab, which can lead to the formation of DTDCs when patients switch between PIASKY and either eculizumab or ravulizumab. These DTDCs comprise one or more units of C5 bound to both PIASKY and to eculizumab or ravulizumab. These DTDCs are expected to be cleared within approximately 8 weeks (in the case of eculizumab) or longer (in the case of ravulizumab) and can result in Type III hypersensitivity reactions [see Warnings and Precautions (5.3) , Adverse Reactions (6.1) and Clinical Pharmacology (12.3) ] .
Warnings
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. 5 WARNINGS AND PRECAUTIONS Type III hypersensitivity reactions: Monitor patients switching from another C5 inhibitor to PIASKY or from PIASKY to another C5 inhibitor as they are at risk of Type III hypersensitivity reactions related to the formation of drug-target-drug complexes ( 5.3 ) Other Infections: PIASKY can increase susceptibility to serious infections especially those caused by encapsulated bacteria. 4 CONTRAINDICATIONS PIASKY is contraindicated: For initiation in patients with an unresolved serious Neisseria meningitidis infection [see Warnings and Precautions (5.1) ]. In patients with a known serious hypersensitivity reaction to crovalimab or any of the excipients [see Warnings and Precautions (5.5) ] .
Pregnancy
8.1 Pregnancy Risk Summary Available data on PIASKY use in pregnant women are insufficient to evaluate for a drug associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Human IgG antibody is known to cross the placenta and its transport increases as pregnancy progresses and peaks during the third trimester; therefore, PIASKY may be transmitted from the mother to the developing fetus. There are risks to the mother and fetus associated with untreated PNH in pregnancy (see Clinical Considerations ).
Storage
16.2 Storage and Handling Store refrigerated at 2°C to 8°C (36°F to 46°F) in the outer carton to protect from light. Do not freeze. Do not shake. Once removed from the refrigerator, the unopened vial can be kept at room temperature up to 30°C (86°F) in its outer carton for no longer than 7 days.
