Guselkumab Brand Name– Tremfya
What is Guselkumab
Guselkumab is a subcutaneously administered interleukin 23 (IL-23) blocker approved for the treatment of adults with moderate-to-severe plaque psoriasis who are candidates for systemic therapy or phototherapy and is also approved for treating psoriatic arthritis (PsA).
Compared to placebo, biologic drugs like guselkumab are able to achieve at least a 90% reduction from baseline in the PASI composite score (PASI 90) for induction therapy in patients with moderate to severe plaque psoriasis, and are more effective than traditional standard treatments.
The ideal therapy for individual patients with plaque psoriasis is determined by treat to target strategies and severity of disease, including the presence or absence of psoriatic arthritis; guselkumab was not specifically evaluated regarding its place in PsA treatment due to ongoing investigation of this agent at the time of publication.
As with other biologics that target interleukins, the drug may increase the risk for infections; all potential drug recipients should be evaluated for active or latent tuberculosis infection prior to initiating therapy
