Dosage
2 DOSAGE AND ADMINISTRATION CABLIVI should be administered upon the initiation of plasma exchange therapy. The recommended dose of CABLIVI is as follows: ( 2.1 ) First day of treatment: 11 mg bolus intravenous injection at least 15 minutes prior to plasma exchange followed by an 11 mg subcutaneous injection after completion of plasma exchange on day 1. Subsequent treatment during daily plasma exchange: 11 mg subcutaneous injection once daily following plasma exchange. Treatment after the plasma exchange period: 11 mg subcutaneous injection once daily for 30 days beyond the last plasma exchange. If after initial treatment course, sign(s) of persistent underlying disease such as suppressed ADAMTS13 activity levels remain present, treatment may be extended for a maximum of 28 days.

Interactions
7 DRUG INTERACTIONS Concomitant use of anticoagulants or antiplatelet agents with CABLIVI may increase the risk of bleeding. Monitor closely for bleeding with concomitant use. ( 7 ) Concomitant Use of Anticoagulants, Thrombolytic Drugs, Heparin or Antiplatelet Agents Concomitant use of CABLIVI with any anticoagulant, thrombolytic drugs, heparin or antiplatelet agent may increase the risk of bleeding. Avoid concomitant use when possible. Assess and monitor closely for bleeding with concomitant use [see Warnings and Precautions (5.1) and Clinical Pharmacology (12.3) ] .
Warnings
5 WARNINGS AND PRECAUTIONS Hemorrhage: Serious and fatal bleeding can occur. Risk of bleeding is increased in patients with underlying coagulopathies or on concomitant antiplatelet agents or anticoagulants. If clinically significant bleeding occurs, interrupt treatment. Withhold CABLIVI 7 days prior to elective surgery, dental procedures, or other invasive interventions. ( 5.1 ) 5.1 Hemorrhage CABLIVI increases the risk of bleeding [see Adverse Reactions (6.1) ] . In clinical studies, severe bleeding adverse reactions of epistaxis, gingival bleeding, upper gastrointestinal hemorrhage, and metrorrhagia were each reported in 1% of subjects. Overall, bleeding events occurred in approximately 58% of patients on CABLIVI versus 43% of patients on placebo. 4 CONTRAINDICATIONS CABLIVI is contraindicated in patients with a previous severe hypersensitivity reaction to caplacizumab-yhdp or to any of the excipients. Hypersensitivity reactions have included urticaria [see Adverse Reactions (6.1) ] . Previous severe hypersensitivity reaction to caplacizumab-yhdp or any of the excipients. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary There are no available data on CABLIVI use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. However, there are potential risks of hemorrhage in the mother and fetus associated with use of CABLIVI (see Clinical Considerations ) .
