Efficacy

Zoryve (roflumilast) for Psoriasis

Zoryve, with the active ingredient roflumilast, is a phosphodiesterase 4 (PDE4) inhibitor indicated for the treatment of plaque psoriasis, including cases that are moderate to severe. The efficacy of Zoryve in treating psoriasis was demonstrated in clinical trials where patients showed significant improvements in their Psoriasis Area and Severity Index (PASI) scores, a measure commonly used to assess the severity of psoriasis. Participants in these trials experienced a reduction in the thickness, scaling, and redness of plaques, which are characteristic symptoms of the condition.

In the clinical trials, Zoryve was evaluated over a 12-week period, where it was applied topically once daily. The results indicated that a substantial proportion of the patients achieved at least a 75% improvement in their PASI score from baseline. This level of improvement is considered clinically meaningful and suggests that Zoryve can be an effective treatment option for individuals with plaque psoriasis, particularly for those who seek a non-systemic treatment approach.

Bimzelx (bimekizumab-bkzx) for Psoriasis

Bimzelx, which contains the active substance bimekizumab-bkzx, is a monoclonal antibody that targets interleukin-17A (IL-17A) and interleukin-17F (IL-17F), two key cytokines involved in the inflammatory process of psoriasis. Bimzelx has shown efficacy in the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy. Clinical trials have demonstrated that Bimzelx can lead to significant skin clearance, as measured by PASI scores, and the Dermatology Life Quality Index (DLQI), which assesses the impact of skin disease on the quality of life.

In pivotal phase 3 trials, Bimzelx was administered through subcutaneous injection, and a high percentage of patients achieved PASI 90 and PASI 100 responses, indicating 90% and 100% improvements in PASI scores, respectively. These outcomes were observed as early as week 16 and were maintained through week 52, highlighting the potential of Bimzelx as a long-term treatment option for psoriasis. The sustained efficacy over time suggests that Bimzelx can offer significant relief from the symptoms of psoriasis and improve the quality of life for patients with this chronic skin condition.
