Patients who were about to initiate Cosentyx® or had started Cosentyx® within the last 4 weeks and met the eligibility criteria were enrolled. Patients were followed via routine visits in real clinical practice up to 52 weeks. Data from medical records, including safety and effectiveness information of Cosentyx® (e.g., AE, SAE, physical examinations, laboratory tests, disease assessments, etc.) were collected at each visit.
