Lanadelumab: A review in hereditary angioedema [Review]

Lanadelumab (Takhzyro TM), a first-in-class fully human monoclonal antibody against plasma kallikrein, has been approved in several countries, including Australia, Canada, those of the EU, Switzerland and the USA, for the prevention of hereditary angioedema (HAE) attacks in patients aged >=12 years. Subcutaneous lanadelumab significantly reduced HAE attack rates relative to placebo in the pivotal HELP trial. The clinical benefits of lanadelumab were seen regardless of prior long-term prophylaxis use, baseline disease activity, sex or body mass index. Lanadelumab therapy was associated with clinically meaningful improvements in HAE-specific quality of life. Lanadelumab was generally well tolerated. The most common adverse events with lanadelumab were injection-site reactions, which were generally mild and transient. Lanadelumab has a low potential for immunogenicity. It offers the convenience of self-administered subcutaneous injections once every 2 weeks (starting dosage). Currently available data indicate that lanadelumab is an effective, well-tolerated, novel prophylactic option for patients with HAE aged >=12 years.
