Plasma Kallikrein Inhibitor, Recombinant Monoclonal Antibody Subcutaneous Vial (ML)
Last reviewed · Source: First Databank (FDB) drug data
Overview
Lanadelumab, a recombinant fully human immunoglobulin G1 (IgG1) monoclonal antibody, is a plasma kallikrein inhibitor.
Lanadelumab-flyo is a recombinant fully human immunoglobulin G1 (IgG1) kappa light chain monoclonal antibody produced in a recombinant Chinese hamster ovary cell line. The drug binds to plasma kallikrein and inhibits its proteolytic activity. Plasma kallikrein is a protease that cleaves high molecular weight kininogen (HMWK), a cofactor formed during activation of the kallikrein-kinin (or contact) pathway, to generate cleaved HMWK (cHMWK) and bradykinin.
In patients with hereditary angioedema (HAE), low plasma concentrations of functionally active complement 1 (C1)-esterase inhibitor result in unrestrained activity of plasma kallikrein and elevated bradykinin levels, leading to increased vascular permeability and angioedema. By decreasing plasma kallikrein activity, lanadelumab controls excess bradykinin generation in patients with HAE. Concentration-dependent inhibition of plasma kallikrein, measured as a reduction of cHMWK concentrations, has been demonstrated following subcutaneous administration of lanadelumab-flyo at dosages of 150 mg every 4 weeks, 300 mg every 4 weeks, and 300 mg every 2 weeks in patients with HAE.
The pharmacokinetics of lanadelumab-flyo are approximately linear following subcutaneous administration of therapeutic doses in patients with HAE. Peak plasma concentrations are achieved in about 4-5 days, and steady state is reached in approximately 70 days. A mean accumulation ratio at steady state of 1.44, 1.42, or 2.43, respectively, was observed in patients receiving a lanadelumab-flyo dosage of 150 mg every 4 weeks, 300 mg every 4 weeks, or 300 mg every 2 weeks.
The elimination half-life of the drug is 14-15 days. The metabolism of lanadelumab-flyo has not been studied but is expected to be consistent with other endogenous antibodies, involving proteolysis in the liver and phagocytic cells of the immune system into small peptides and amino acids. Exposure to lanadelumab decreases with increasing body weight; however, this difference is not considered clinically important.
Age, sex, and race do not appear to affect the pharmacokinetics of the drug after correcting for body weight.
USES: This medication is used to help prevent severe swelling attacks due to a certain inherited immune disease (hereditary angioedema-HAE). Lanadelumab works by binding to a natural substance made by the body (kallikrein) and blocking its effect. This blocking effect lowers the amount of another natural substance (bradykinin) that causes symptoms during an attack of HAE.
Lanadelumab may help decrease symptoms such as abdominal pain/cramps, diarrhea, vomiting, or rapid swelling and pain of the hands, feet, limbs, face, tongue, or throat.

Drug interactions
No formal drug interaction studies with lanadelumab-flyo have been performed to date.
Use of rescue medications, such as plasma-derived and recombinant complement 1 (C1)-esterase inhibitor (human), icatibant, or ecallantide, for breakthrough hereditary angioedema attacks had no effect on clearance and volume of distribution of lanadelumab. In addition, the manufacturer states that concomitant use of analgesic, antibacterial, antihistamine, anti-inflammatory, or antirheumatic drugs had no effect on clearance and volume of distribution of lanadelumab.
There are no contraindication interactions for this drug.
Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
Igg Antibodies And Derivatives/Efgartigimod-Alfa
SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction.
MECHANISM OF ACTION: The neonatal Fc receptor (FcRn) prevents catabolism and mediates recycling of IgG and albumin, which leads to their long persistence in the body.(1,2) Efgartigimod-alfa binds to FcRn and may decrease systemic exposure of other ligands of FcRn, like immunoglobulins and IgG-based antibodies.(3)

Safety and efficacy of lanadelumab-flyo have not been established in pediatric patients <2 years of age. Among the 125 patients included in the initialpivotal clinical trial of lanadelumab, 10 patients were 12 to <18 years of age; subgroup analysis in such patients indicated that safety and efficacy were consistent with overall study results. An additional 13 pediatric patients aged 12 to <18 years were enrolled in the open-label extension study.
Use of landelumab-flyo in patients 2 to <12 years of age was supported by extrapolation of efficacy datafrom the initial pivotal clinical trial, withadditional pharmacokinetic analyses showing similar drug exposures between adults (>18 years of age) and pediatric patients (2to <12 years of age), and safety and pharmacodynamic data from an open-label, multicenter study in pediatric patientswith HAE aged 2 to <12 years that enrolled 21 patients. The pharmacodynamic responseobserved in this trial for pediatric patients 2 to <12 years of age was similar to that seen in adult and pediatric patients >=12years of age.
An increase in lanadelumab AUC of about 37% has been reported in pediatric patients 12 to <18 years of age compared with adults; this difference is thought to be due to lower body weight and is not considered clinically important. Lanadelumab treatment is not expected to impact growth.
Data are not available regarding the use of lanadelumab in pregnant women. Monoclonal antibodies are transported across the placenta during the third trimester of pregnancy; therefore, the potential for effects of lanadelumab on the fetus is expected to be greater during the third trimester.
In animal studies, no effects on maintenance of pregnancy, parturition, or on embryofetal development, survival, growth, or postnatal development were observed in cynomolgus monkeys administered lanadelumab subcutaneously once weekly from the period of organogenesis through parturition at dose exposures up to 33 times those achieved with the maximum recommended human dose. Lanadelumab has been shown to cross the placenta in monkeys.
It is not known whether lanadelumab is distributed into human milk, affects milk production, or affects breast-fed infants. The drug has been detected in milk in monkeys. Because lanadelumab is a large protein molecule, the amount distributed into breast milk is expected to be very low; in addition, any amount present in breast milk is likely to be destroyed in the infant's GI tract, resulting in minimal absorption.
Consider the developmental and health benefits of breast-feeding along with the mother's clinical need for lanadelumab and any potential adverse effects on the breast-fed infant from the drug or from the underlying maternal condition.
The manufacturer makes no specific dosage recommendations for geriatric patients.
Of the 125 patients with HAE who were studied in the pivotal clinical trial of lanadelumab, 4% were >=65 years of age. Although no overall differences in safety or efficacy were observed between these patients and younger adults, the possibility that some older patients may exhibit increased sensitivity to the drug cannot be ruled out.
