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 )

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 )

5.1Hemorrhage

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. In the postmarketing setting, cases of life-threatening and fatal bleeding were reported in patients receiving CABLIVI.

The risk of bleeding is increased in patients with underlying coagulopathies (e.g., hemophilia, other coagulation factor deficiencies). It is also increased with concomitant use of CABLIVI with drugs affecting hemostasis and coagulation [see Drug Interactions (7) and Clinical Pharmacology (12.3) ] . Avoid concomitant use of CABLIVI with antiplatelet agents, thrombolytic drugs, heparin, or anticoagulants. Interrupt use of CABLIVI if clinically significant bleeding occurs.

If needed, von Willebrand factor concentrate may be administered to rapidly correct hemostasis. If CABLIVI is restarted, monitor closely for signs of bleeding. Withhold CABLIVI for 7 days prior to elective surgery, dental procedures or other invasive interventions. If emergency surgery is needed, the use of von Willebrand factor concentrate may be considered to correct hemostasis. After the risk of surgical bleeding has resolved, and CABLIVI is resumed, monitor closely for signs of bleeding.

8.1Pregnancy 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 ) . In animal reproduction studies, there was no evidence of adverse developmental outcomes with intramuscular administration of caplacizumab-yhdp during organogenesis in guinea pigs at exposures approximately 30 times the AUC in humans at the recommended subcutaneous injection dose of 11 mg (see Data ) .

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background rate of major birth defects and miscarriage in the indicated population is unknown. In the U.S. general population, the estimated background rate of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Fetal/neonatal adverse reactions CABLIVI may increase the risk of bleeding in the fetus and neonate.

Monitor neonates for bleeding [see Warnings and Precautions (5.1) ] . Maternal adverse reactions All patients receiving CABLIVI, including pregnant women, are at risk for bleeding. Pregnant women receiving CABLIVI should be carefully monitored for evidence of excessive bleeding [see Warnings and Precautions (5.1) ] . Data Animal data Two separate reproduction studies were conducted in pregnant guinea pigs with administration of caplacizumab-yhdp during the organogenesis period.

In an embryo-fetal development study, caplacizumab-yhdp was administered intramuscularly at doses up to 20 mg/kg/day from gestational day (GD) 6 to GD 41 in guinea pigs. No maternal toxicity or adverse developmental outcomes were observed. In a toxicokinetic study assessing the exposure of caplacizumab-yhdp in the dams and fetuses, caplacizumab-yhdp was administered once daily to female guinea pigs at doses up to 40 mg/kg/day (corresponding to a drug exposure of approximately 30 times the AUC in humans at the recommended dose of 11 mg) by intramuscular injection from GD 6 to GD 41 or GD 61.

Exposure to caplacizumab-yhdp was observed in the dams and fetuses, with no effects on embryo-fetal development.

Adverse reactions

The following clinically significant adverse reactions are also discussed in other sections of the labeling: Hemorrhage [see Warnings and Precautions (5.1) ] In adults, the most common adverse reactions (incidence >15%) are epistaxis, headache, and gingival bleeding. In pediatric patients, the most frequently reported adverse reactions are epistaxis and tachycardia.

6.1Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. TITAN and HERCULES The safety of CABLIVI was evaluated in two placebo-controlled clinical studies (HERCULES, in which 71 patients received CABLIVI; and TITAN, in which 35 patients received CABLIVI).

The data described below and in the Warnings and Precautions reflect exposure to CABLIVI during the blinded periods of both studies, which include 106 patients with aTTP who received at least one dose, age 18 to 79 years, of whom 69% were female and 73% were White. The median treatment duration with CABLIVI was 35 days (range 1–77 days). The most frequently reported adverse reactions (>15%) were epistaxis, headache and gingival bleeding.

Seven patients (7%) in the CABLIVI group experienced an adverse reaction leading to study drug discontinuation. None of the adverse reactions leading to discontinuation were observed in more than 1% of patients. Among 106 patients treated with CABLIVI during the TITAN and HERCULES studies, serious bleeding adverse reactions reported in ≥2% patients included epistaxis (4%) and subarachnoid hemorrhage (2%). Adverse reactions that occurred in ≥2% of patients treated with CABLIVI and more frequently than in those treated with placebo across the pooled data from the two trials are summarized in Table 1.

Urticaria was seen during plasma exchange.

The most commonly reported events were epistaxis in 4 (13.3%) patients and tachycardia in 4 (13.3%) patients. One serious bleeding adverse reaction (hemorrhage urinary tract) was reported. The adverse reaction profile in pediatric patients 12 years and older with aTTP was consistent with that in adults.

6.3Postmarketing Experience

The following adverse reactions have been identified during postapproval use of CABLIVI. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to caplacizumab-yhdp exposure. General disorders and administration site conditions: Injection site reactions including injection site pain, injection site bruising and injection site erythema
