Randomized Controlled Trial
Secukinumab efficacy and safety in Japanese patients with moderate-to-severe plaque psoriasis: subanalysis from ERASURE, a randomized, placebo-controlled, phase 3 study.
Secukinumab, a fully human anti-IL-17A monoclonal antibody, neutralizes IL-17A, a key cytokine in the pathogenesis of psoriasis. Efficacy and safety of secukinumab was evaluated in Japanese patients with moderate-to-severe plaque psoriasis as part of a large Phase 3 global study (ERASURE). In this 52-week, double-blind study (ClinicalTrials.gov Identifier: NCT01365455, JapicCTI-111529), 87 patients from Japan (11.8% of 738 patients randomized in the overall study population) were equally randomized to receive secukinumab 300 mg or 150 mg, or placebo once weekly at baseline and at Weeks 1, 2, 3 and 4, then every 4 weeks. ⋯ Clinical responses were sustained up to Week 52 in the majority of patients. During a 12-week induction period, adverse event incidences were 48.3% with secukinumab 300 mg, 55.2% with 150 mg, and 41.4% with placebo. Secukinumab showed robust and sustainable efficacy in symptom reduction for moderate-to-severe plaque psoriasis in the Japanese patients.

The major goal of this study was the identification of predictors for motor function and survival after irradiation alone for metastatic epidural spinal cord compression (MESCC) from melanoma. Ten variables (age, gender, performance status, number of involved vertebrae, pre-radiotherapy ambulatory status, further bone metastases, visceral metastases, interval from melanoma diagnosis to MESCC, time developing motor deficits before radiotherapy, fractionation regimen) were investigated for post-radiotherapy motor function, ambulatory status and survival in 27 patients. On multivariate analysis, motor function was significantly associated with time developing motor deficits (P = 0.006). ⋯ The newly developed survival score included three prognostic groups. Patients with 3 points may receive 1 × 8 Gy, patients with 9 points 5 × 4 Gy and patients achieving 15 points longer-course radiotherapy. In the latter two groups, upfront decompressive surgery may be considered.
