Indication

Lanadelumab is indicated for the prophylaxis treatment to prevent attacks in patients 12 years and older with hereditary angioedema.⁵

The hereditary angioedema (HEA) is an autosomal dominant disorder resulted from the presence of C1 deficiency. Some reports have indicated a high prevalence of cases that result from spontaneous mutations which can be inherited. This condition is manifested by attacks of subcutaneous or submucosal edema in the face, larynx, GI tract, limbs or genitalia. From all the types of attacks, the most serious is the laryngeal as it can compromise the airway. The rest of the attacks are accompanied by pain and considerable dysfunction.⁴

Pharmacodynamics

In phase 1 studies, the level of kininogen, the substrate of kallikrein, was studied as a marker of kallikrein activity. In patients with C1 deficiency, the level of cleaved kininogen is 4-fold higher when compared with C1-normal individuals. When lanadelumab was administered, the levels of cleaved kininogen were significantly reduced with a dose of 300 and 400 mg of lanadelumab with a maximum reduction at day 22 corresponding with time for maximum concentration. This maximum reduction corresponded with the normal levels of cleaved kininogen. Similarly, the decreases of cleaved kininogen corresponded as well with reductions in the levels of the activated factor XII.²

Clinically, the attacks of angioedema completely vanished in the patients receiving a dose of 300 mg of lanadelumab. In other doses such as 400 mg and combo 300/400 mg the attack reduction reached 90%.²

In phase 3 clinical trials (HELP study, lanadelumab showed an attack rate reduction of over 70% for all three different dose regimes.¹

Mechanism of action

Lanadelumab is a plasma kallikrein inhibitor. This enzyme works by cleaving high molecular weight kininogen to generate the pro-inflammatory peptide bradykinin which is a potent vasodilator. The activity of plasma kallikrein is regulated by the activity of C1-inhibitor and thus, the patients that are deficient in C1 are known to be correlated to excessive production of bradykinin which will further lead to fatal angioedema.³ Hence, lanadelumab occludes the proteolytic active site of plasma kallikrein, preventing the cleavage of kininogen to bradykinin. It is a selective inhibitor as it has been reported that lanadelumab does not bind to prekallikrein or to inhibit any other serine proteases.⁴ The activity of lanadelumab works as an additional checkpoint for the patients suffering from C1 deficiency.

Absorption

The drug levels of lanadelumab are dose-dependent and thus, the maximum plasma concentration increased correspondingly with an increased dosage. The Cmax and AUC ranged from 3800 to 45000 ng/ml and from 64000 to 762000 ng.day/ml respectively for concentrations from 30 to 400 mg. As well, sustained quantifiable drug concentration was observed through day 120.² The bioavailability of lanadelumab is of approximately 66% with a time to reach peak drug concentration of approximately 7 days.⁴

Volume of distribution

The reported volume of distribution of lanadelumab is in the range of 12 to 16 L which variates according to the dose administered.⁴

Protein binding

General information on plasma protein binding is not available but it is considered that, as the site of action is with plasma proteins, the percentage of protein binding should be significant.

Metabolism

Because lanadelumab is a protein, it is expected to be degraded into small peptides and amino acids by proteolytic enzymes.

Route of elimination

The main excretion is thought to be done in the urine but this has not been confirmed and further studies are required.

Half-life

Lanadelumab has a prolonged half-life which is typical of a human monoclonal antibody and it ranged from 13.8 to 15 days.²

Clearance

The apparent total plasma clearance after extravascular administration ranges between 18 and 25 ml/h.²
