| Primary | Persistency of Response and Non-response as Based on Investigator's Global Evaluation of Treatment Effectiveness (GETE) | Persistency of response, based on GETE, was dichotomized into responders (excellent or good) and non-responders (moderate, poor or worsening). Persistent responders were patients who were responders at 16 weeks and still at 32 weeks. Persistent non-responders were patients who were non-responders at 16 weeks and still at 32 weeks. Patients were assessed for persistency of response if they were responders at Week 16 and had a second GETE obtained ≥ 4 weeks after the Week 16 assessment or discontinued prematurely for unsatisfactory therapeutic effect ≥ 4 weeks after the Week 16 assessment. | Modified Intent-to-Treat (mITT) was defined for efficacy analyses which included all randomized patients who had at least one post-baseline efficacy assessment. | Posted | | Number | | participants | | Weeks 16 and 32 | | | | ID | Title | Description |
