Efficacy and Safety Analysis in Chinese Patients with Moderate-to-Severe Psoriasis from a Phase 3 Trial: Impact of Treatment Withdrawal and Retreatment of Ixekizumab.
Introduction: In China, approximately 2.3 million people have psoriasis. Continuous treatment is recommended for moderate-to-severe psoriasis. This study aimed to evaluate the outcomes of continuous versus interrupted ixekizumab (IXE) treatment and retreatment with IXE after disease worsening in Chinese patients.
Methods: In this Phase 3, multicenter, randomized, double-blind, placebo-controlled study, patients were randomized to IXE or placebo at Week 0. At Week 12, IXE responders (static Physician's Global Assessment [sPGA] score, 0 or 1 [0,1]) were re-randomized (2:1) to IXE (IXE/IXE, continuous treatment) or placebo (IXE/PBO, interrupted treatment). After re-randomization, treatment in IXE/PBO patients with disease worsening (relapse, sPGA ≥ 3) was switched to IXE every 4 weeks (IXE/PBO + IXEQ4W, retreatment). Efficacy was assessed by evaluating the response rates of Psoriasis Area and Severity Index (PASI) 75/90/100, sPGA (0,1), Dermatology Life Quality Index (DLQI) (0,1), mean PASI, and Itch Numerical Rating Scale (NRS) scores and improvements of special body areas. Safety was evaluated by assessing treatment-emergent adverse events (AEs) and serious AEs.
Results: At Week 12, 289 IXE responders were re-randomized to the IXE/IXE group (192 patients) and IXE/PBO group (97 patients). High rates of PASI 75 and sPGA (0, 1) responses were maintained in the IXE/IXE group until Week 60. At Week 60, 88 (90.7%) patients in the IXE/PBO group had disease relapse; the median time to relapse was approximately 20 weeks. After 24 weeks of retreatment, PASI 75 and sPGA (0, 1) were recaptured (97.2% and 74.6%, respectively, in the IXE/PBO + IXEQ4W group). AEs were comparable in patients who received continuous treatment and retreatment.
Conclusion: In Chinese patients who received continuous IXE treatment, high response rates were maintained through 60 weeks. Most patients had disease relapse after treatment withdrawal. After retreatment, most of these patients had regained and maintained response since Week 12.
期刊介绍：
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
