Cablivi
(caplacizumab-yhdp)Dosage & Administration
Cablivi Prescribing Information
CABLIVI is indicated for the treatment of adult patients with acquired thrombotic thrombocytopenic purpura (aTTP), in combination with plasma exchange and immunosuppressive therapy.
Recommended Dose and Schedules
CABLIVI should be administered upon initiation of plasma exchange therapy. The recommended dose of CABLIVI is as follows:
- 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 days of treatment during daily plasma exchange: 11 mg subcutaneous injection once daily following plasma exchange.
- Treatment after plasma exchange period: 11 mg subcutaneous injection once daily continuing for 30 days following the last daily 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.
Discontinue CABLIVI if the patient experiences more than 2 recurrences of aTTP, while on CABLIVI.
Avoid concomitant use of antiplatelet agents or anticoagulants [see Warnings and Precautions (5.1)].
Missed Dose
If a dose of CABLIVI is missed during the plasma exchange period, it should be given as soon as possible. If a dose of CABLIVI is missed after the plasma exchange period, it can be administered within 12 hours of the scheduled time of administration. Beyond 12 hours, the missed dose should be skipped and the next daily dose administered according to the usual dosing schedule.
Discontinuation for Surgery and Other Interventions
Withhold CABLIVI treatment 7 days prior to elective surgery, dental procedures, or other invasive interventions [see Warnings and Precautions (5.1)].
Reconstitution and Administration Instructions
The first dose of CABLIVI should be administered by a healthcare provider as a bolus intravenous injection. Administer subsequent doses subcutaneously in the abdomen. Avoid injections around the navel. Do not administer consecutive injections in the same abdominal quadrant.
Patients or caregivers may inject CABLIVI subcutaneously after proper training on the preparation and administration of CABLIVI, including aseptic technique [see Instructions for Use].
- Ensure the CABLIVI vial and diluent syringe are at room temperature.
- Reconstitute CABLIVI before administration using the provided syringe containing 1 mL Sterile Water for Injection, USP, to yield an 11 mg/mL single-dose solution.
- Using aseptic technique throughout the preparation of the solution, attach the vial adapter to the vial containing CABLIVI.
- Remove the plastic cap from the syringe and attach it to the vial adapter by twisting it clockwise until it cannot twist any further.
- Slowly push the syringe plunger down until the syringe is empty. Do not remove the syringe from the vial adapter.
- Gently swirl the vial until the cake or powder is completely dissolved. Do not shake.
- Visually inspect that the reconstituted solution is clear and colorless.
- Withdraw all of the clear, colorless reconstituted solution from the vial into the syringe. Label the CABLIVI syringe.
- Administer the full amount of reconstituted solution.
- For the initial intravenous injection, if using an intravenous line, the glass syringe should be connected to a standard Luer lock (and not a needleless connector) and flushed with either 0.9% Sodium Chloride Injection, USP, or 5% Dextrose Injection, USP.
- Use the CABLIVI solution immediately. If not, use CABLIVI within 4 hours after reconstitution when stored in the refrigerator at 2°C to 8°C (36°F to 46°F).
For injection: 11 mg as a white lyophilized powder in a single-dose vial.
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). 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.
Lactation
Risk Summary
There is no information regarding the presence of caplacizumab-yhdp in human milk, the effects on the breastfed child or the effects on milk production.
The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for CABLIVI and any potential adverse effects on the breastfed child from CABLIVI, or from the underlying maternal condition.
Pediatric Use
The safety and effectiveness of CABLIVI in pediatric patients have not been established.
Geriatric Use
Clinical studies of CABLIVI did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
Hepatic Impairment
No formal studies with CABLIVI have been conducted in patients with severe acute or chronic hepatic impairment and no data regarding the use of CABLIVI in these populations are available. Due to a potential increased risk of bleeding, use of CABLIVI in patients with severe hepatic impairment requires close monitoring for bleeding [see Warnings and Precautions (5.1)].
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)].
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.
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 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.
The following clinically significant adverse reactions are also discussed in other sections of the labeling:
- Hemorrhage [see Warnings and Precautions (5.1)]
Clinical 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.
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.

Immunogenicity
As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to caplacizumab-yhdp in the studies described below, with the incidence of antibodies in other studies, or to other products, may be misleading.
The prevalence of pre-existing antibodies binding to caplacizumab-yhdp observed during clinical studies and during evaluation of commercially available human samples varied between 4% and 63%. In aTTP patients, pre-existing antibodies can be produced by the patient or can originate from donor plasma during plasma exchange. No clinically apparent impact of these pre-existing antibodies on clinical efficacy or safety was found. Treatment-emergent anti-drug antibodies (TE ADA) against caplacizumab-yhdp were detected in 3% of patients treated with CABLIVI in the HERCULES study. In the HERCULES study, TE ADA were further characterized as having neutralizing potential. There was no clinically apparent impact on clinical efficacy or safety [see Clinical Pharmacology (12.3)].
Postmarketing 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
Concomitant Use of Anticoagulants or Antiplatelet Agents
Concomitant use of CABLIVI with any anticoagulant 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)].
Caplacizumab-yhdp is a von Willebrand factor (vWF)-directed antibody fragment that consists of two identical humanized building blocks, linked by a three-alanine linker. Caplacizumab-yhdp is produced in Escherichia coli by recombinant DNA technology and has an approximate molecular weight of 28 kDa.
CABLIVI (caplacizumab-yhdp) for injection is a sterile, white, preservative-free, lyophilized powder. Each single-dose vial delivers 11 mg caplacizumab-yhdp, anhydrous citric acid (0.18 mg), polysorbate 80 (0.10 mg), sucrose (62 mg), and trisodium citrate dihydrate (4.91 mg). After reconstitution with 1 mL of Sterile Water for Injection, USP, the final concentration is 11 mg/mL, at a pH of approximately 6.5.
Mechanism of Action
Caplacizumab-yhdp targets the A1-domain of vWF, and inhibits the interaction between vWF and platelets, thereby reducing both vWF-mediated platelet adhesion and platelet consumption.
Pharmacodynamics
Ristocetin cofactor (RICO) activity was used to assess vWF activity. Subcutaneous doses of caplacizumab-yhdp at greater than or equal to the approved recommended dosage to healthy subjects and patients with aTTP decreased RICO activity levels to below 20% approximately 4 hours post-dose. RICO activity returned to baseline values within 7 days of drug discontinuation.
Caplacizumab-yhdp decreased vWF antigen and factor VIII:C levels. These reductions were transient and returned to baseline upon cessation of treatment.
Pharmacokinetics
Caplacizumab-yhdp pharmacokinetics depends on the expression of the target vWF and are not dose proportional. Higher levels of vWF antigen increase the fraction of drug-target complex retained in the circulation. Steady-state was reached following the first administration of CABLIVI in healthy subjects, with minimal accumulation. Following a single subcutaneous dose of 10 mg caplacizumab-yhdp to healthy subjects the mean (CV%) peak concentration (Cmax) was 528 (20%) ng/mL and AUC0–24 was 7951 (16%). Following subcutaneous dosing of 10 mg caplacizumab-yhdp daily for 14 days to healthy subjects, the mean (CV%) Cmax was 348 (30%) ng/mL and AUC0–τ was 6808 (26%) hr∙ng/mL.
Absorption
The bioavailability of subcutaneous caplacizumab-yhdp is approximately 90%.
The maximum concentration was observed 6 to 7 hours after subcutaneous dosing of 10 mg caplacizumab-yhdp once daily in healthy subjects.
Distribution
Caplacizumab-yhdp central volume of distribution is 6.33 L in patients with aTTP.
Elimination
The half-life of caplacizumab-yhdp is concentration and target-level dependent.
Metabolism
The available data suggest target-bound caplacizumab-yhdp is metabolized within the liver. Because caplacizumab-yhdp is a monoclonal antibody fragment, it is expected to be catabolized by various proteolytic enzymes.
Excretion
The available nonclinical data suggest unbound caplacizumab-yhdp is cleared renally.
Antidrug Antibodies
No clinically significant differences in the pharmacokinetics of caplacizumab-yhdp were observed in patients with pre-existing or treatment-emergent anti-drug antibodies.
Specific Populations
No clinically significant differences in the pharmacokinetics of caplacizumab-yhdp were observed based on age (18 to 79 years), sex (66% females), race (White [83%] and Black [17%]), blood group (O [41%] and other groups [59%]), or renal impairment (mild [CrCl: 60 to 90 mL/min], moderate [CrCl: 30 to 60 mL/min] or severe [CrCl: 15 to 30 mL/min]). The effect of hepatic impairment on the pharmacokinetics of caplacizumab-yhdp is unknown [see Use in Specific Populations (8.6)].
Drug Interaction Studies
No dedicated drug-drug interaction studies with caplacizumab-yhdp have been conducted.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No studies have been performed to evaluate the potential of caplacizumab-yhdp for carcinogenicity or genotoxicity.
Animal reproduction studies assessing the effects of caplacizumab-yhdp on male and female fertility have not been conducted.
The efficacy of CABLIVI for the treatment of adult patients with acquired thrombotic thrombocytopenic purpura (aTTP) in combination with plasma exchange and immunosuppressive therapy was established in a pivotal multicenter, randomized, double-blind, placebo-controlled trial (HERCULES) (NCT02553317).
A total of 145 patients were enrolled in the HERCULES study; the median age was 45 (range: 18 to 79) years, 69% were female, 73% were White. Patients were randomized to either CABLIVI (n=72) or placebo (n=73). Patients in both groups received plasma exchange and immunosuppressive therapy. Patients were stratified according the severity of neurological involvement (Glasgow Coma Scale score ≤12 or 13 to 15). Patients with sepsis, infection with E. coli 0157, atypical hemolytic uremic syndrome, disseminated intravascular coagulation or congenital thrombotic thrombocytopenic purpura were not eligible for enrollment.
Patients received a single 11 mg CABLIVI bolus intravenous injection or placebo prior to the first plasma exchange on study, followed by a daily subcutaneous injection of 11 mg CABLIVI or placebo after completion of plasma exchange, for the duration of the daily plasma exchange period and for 30 days thereafter. If after the initial treatment course, sign(s) of persistent underlying disease such as suppressed ADAMTS13 activity levels remained present, treatment was extended for 7 day intervals for a maximum of 28 days.
The median treatment duration with CABLIVI was 35 days.
The clinical trial protocol specified the CABLIVI dose as 10 mg, to be delivered by withdrawing all of the reconstituted solution from the vial and administering the full amount. A dose recovery study showed that the mean dose that can be withdrawn from a vial is 11 mg. Therefore, based on the dose recovery study, the mean dose delivered in the trial was 11 mg.
The efficacy of CABLIVI in patients with aTTP was established based on time to platelet count response (platelet count ≥150,000/µL followed by cessation of daily plasma exchange within 5 days). Time to platelet count response was shorter among patients treated with CABLIVI, compared to placebo.
Figure 1: Platelet Response over Time
Treatment with CABLIVI resulted in a lower number of patients with TTP-related death, recurrence of TTP, or at least one treatment-emergent major thromboembolic event (a composite endpoint) during the treatment period (see Table 2).

TTP-related death | 0 | 3 (4.1) |
Recurrence of TTP (exacerbation) † | 3 (4.2) | 28 (38.4) |
At least one treatment-emergent major thromboembolic event | 6 (8.5) | 6 (8.2) |
Total ‡ | 9 (12.7) | 36 (49.3) |
The proportion of patients with a recurrence of TTP in the overall study period (the drug treatment period plus the 28-day follow-up period after discontinuation of drug treatment) was lower in the CABLIVI group (9/72 patients [13%]) compared to the placebo group (28/73 patients [38%] (p<0.001). In the 6 patients in the CABLIVI group who experienced a recurrence of TTP during the follow-up period (i.e., a relapse defined as recurrent thrombocytopenia after initial recovery of platelet count (platelet count ≥150,000/µL) that required reinitiation of daily plasma exchange, occurring after the 30-day post daily plasma exchange period), ADAMTS13 activity levels were <10% at the end of the study drug treatment, indicating that the underlying immunological disease was still active at the time CABLIVI was stopped.
