Brodalumab is a fully human monoclonal antibody targeting the interleukin-17 receptor A (IL-17RA). It is used primarily for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. The drug is approved in several countries, including the US, EU, and Japan, for this indication.
Pharmacokinetics
Population pharmacokinetics in adult patients with moderate to severe plaque psoriasis. Data are primarily from healthy adults and patients aged 18-75 years. Parameters are reported following subcutaneous administration.
