Cablivi (caplacizumab or caplacizumab-yhdp) is the first medication available for the treatment of acquired thrombotic thrombocytopenic purpura (aTTP) in adults. In order for it to work, it must be taken in combination with plasma exchange and immunosuppressants (medications that lower your immune system). After a starting dose that's given through your veins by a healthcare provider, Cablivi (caplacizumab) is injected under the skin daily. Treatment typically lasts a little over 1 to 2 months. Some common side effects include bloody nose, headache, and bleeding gums.
Acquired thrombotic thrombocytopenic purpura (aTTP), in combination with plasma exchange and immunosuppressants (medications that lower your immune system)
Cablivi (caplacizumab) treats aTTP by sticking to von Willebrand factor (vWF) in your blood. This prevents your platelets from clumping together to form clots and also keeps your platelet level in the rest of your body from dropping too low.

Your first dose of Cablivi (caplacizumab) will be given to you by a healthcare provider in the hospital as an IV injection. Then, you or your caregiver can give you the rest of the Cablivi (caplacizumab) injections under the skin at home.
Read the instructions on how to mix the medication and how to give yourself Cablivi (caplacizumab) injections. Make sure your provider or pharmacist teach you how to give yourself Cablivi (caplacizumab) so that you avoid accidentally hurting yourself or wasting the medication. Contact your provider or pharmacist if you have any questions on how to use this medication.
Before using Cablivi (caplacizumab), take the medication out of the refrigerator. Hold the vial and syringe in your hand for 10 seconds to warm them up. Don't try to warm it up any other way, such as with a microwave, because doing so can damage your medication.
Cablivi (caplacizumab) must be mixed before you inject it. Each carton comes with a vial of medication and a s__yringe with sterile water__ that must be added to the vial. Don't inject the contents of the vial without first mixing it with the sterile water.
Use Cablivi (caplacizumab) immediately after mixing. However, if this isn't possible, you can store it for up to 4 hours in the refrigerator.
After you inject Cablivi (caplacizumab), throw away the syringe and needle in a sharps container or something made of heavy-duty plastic, such as an empty milk carton or laundry detergent bottle, to lower the risk of needle-stick injuries. Don't throw away them away in your trash can. When your sharps container is almost full, close it tightly with the cap. For more information on how to throw away your sharps container safely and guidance for your specific state, visit the FDA's website.
Store Cablivi (caplacizumab) in the refrigerator in the original carton to protect it from light. However, for convenience, you can store Cablivi (caplacizumab) at room temperature for up to 2 months. Once placed at room temperature, don't put it back in the refrigerator.
Let your provider know in advance if you're scheduled for a surgery or procedure that might cause bleeding, including dental procedures. Your provider might ask you to stop taking Cablivi (caplacizumab) 7 days before you undergo any surgery or procedure, since Cablivi (caplacizumab) raises your risk for bleeding.
Make sure to tell your provider about all the medications you're taking before starting Cablivi (caplacizumab), especially if you're taking an antiplatelet, such as aspirin, or an anticoagulant, such as warfarin (Coumadin), because these raise your risk for bleeding. Don't start any new medications while taking Cablivi (caplacizumab) without talking to your provider or pharmacist first.
Cablivi (caplacizumab) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Bleeding problems | Taking medications together with Cablivi (caplacizumab) that raise your bleeding risk
Cablivi (caplacizumab) can put you at risk for serious bleeds, especially if you have bleeding problems or if you're taking medications that raise your risk for bleeding (e.g., antiplatelets and anticoagulants). Make sure to tell your provider about all the medications you're taking before starting Cablivi (caplacizumab). Don't start any new medications while taking Cablivi (caplacizumab) without talking to your provider first.
Let your provider know ahead of time if you're planning to receive any surgery, procedure, or dental work. Your provider might have you stop Cablivi (caplacizumab) about 1 week before these procedures to lower your risk for bleeds. If you're getting an emergency surgery, let your provider know you're taking Cablivi (caplacizumab) because you might need to receive additional medications ahead of time to prevent bleeds. If you have any signs of severe bleeding (e.g., fast heart rate, dizziness, light-headedness, pale skin, blood in urine or stool, vomiting or couging up blood) or having difficulty stopping a bleed, get medical help right away.

1st day of treatment: The typical dose is 11 mg of Cablivi (caplacizumab) injected into the veins (IV) at least 15 minutes before plasma exchange by a healthcare provider. Another 11 mg of Cablivi (caplacizumab) is injected under the skin after your plasma exchange.
Treatment during daily plasma exchange: The typical dose is 11 mg of Cablivi (caplacizumab) injected under the skin daily after plasma exchange.
