 Once participants complete the 12- week treatment period, they will be tapered off the study agent. After the taper has been completed, they may be treated with any therapy or pharmacological intervention that their physician feels is clinically indicated. Although we will be collecting data for one year after participants complete the treatment phase, our primary outcome measures will be collected at the end of the 12th week of the treatment period. We will record all concomitant medications used during the study and all medications being used at the follow-ups for data analysis.
