Efficacy of Taltz (Ixekizumab) in Treating Psoriasis

Taltz (ixekizumab) is a biologic medication approved by the U.S. Food and Drug Administration (FDA) for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy or phototherapy. Ixekizumab is a monoclonal antibody that selectively targets interleukin-17A (IL-17A), a cytokine that plays a key role in the pathogenesis of psoriasis. Clinical trials have demonstrated that Taltz can lead to significant skin clearance. In these studies, many patients achieved a 75% reduction in the Psoriasis Area and Severity Index (PASI 75) score within 12 weeks of treatment, and some even achieved PASI 90 or PASI 100, indicating nearly complete or complete clearance of skin lesions.

The long-term efficacy of Taltz has also been evaluated in extension phases of clinical trials, where the therapeutic effects were sustained for many patients over a period of up to 60 weeks. The safety and efficacy of Taltz have been consistent across various demographic and baseline characteristic groups, including patients with different severities of psoriasis and those with or without psoriatic arthritis.

Efficacy of Stelara (Ustekinumab) in Treating Psoriasis

Stelara (ustekinumab) is another biologic medication approved by the FDA for the treatment of moderate to severe plaque psoriasis in adults. Ustekinumab works by targeting interleukins 12 and 23, which are believed to be involved in inflammatory and immune responses, including the inflammation that occurs in psoriasis. Clinical trials have shown that Stelara can produce significant improvement in patients with plaque psoriasis. A substantial proportion of patients treated with Stelara achieved PASI 75 within 12 weeks, and further improvements were often observed with continued treatment.

Long-term studies have supported the sustained efficacy of Stelara, with many patients maintaining their treatment response for over a year. Additionally, Stelara has been shown to improve quality of life and is generally well-tolerated by patients. The drug's dosing schedule, which starts with an initial dose followed by a second dose four weeks later and then maintenance doses every 12 weeks, may be convenient for patients compared to the more frequent dosing requirements of some other biologics.
