According to one expert, recently completed phase 3 trials of novel drugs have shown impressive results, with 2021 expected to be an exciting year that will bring further advances in treatment options for patients with moderate-to-severe plaque psoriasis.

Several systemic therapies are available for the treatment of patients with moderate to severe psoriasis. Continued research has further elucidated the immunopathogenesis of the disease, leading to the development of novel biologic agents that are proving to more effectively and safely address moderate to severe psoriatic lesions.

Genetic polymorphisms may increase psoriasis susceptibility, according to a study that found patients who have the G allele in the JAK1 gene have twice the risk of developing psoriasis, and for those with the JAK3 allele, the risk rises nearly 2-fold.

In a recent study, psoriasis drugs showed widely variable drug survival rates, owing to differences in safety, efficacy, patient satisfaction and other factors. However, concerns linger over potential to cause long-term cumulative organ toxicity.

Comorbidities, co-medication, organ impairment, functional deterioration and frailty make treatment plans challenging for older psoriasis patients. However, these patients should not be precluded but will require more extensive evaluation and assessment, according to a recent study.

A majority of psoriasis patients in phase 3 clinical trials for biologics are white, says authors of a recent study. As ethnicity and race may play a role in response to biologics, researchers emphasize need for more diversity in clinical trials.
