• Status: Completed
• Trial end date: 2010-07-01
• Target enrollment: 0
• Participant gender: Female

Summary

This is a 9-week single-centre, open-label, dose-escalating study evaluating the efficacy and safety of Quetiapine XR given as monotherapy in the treatment of non-lactating, post-partum women diagnosed with Bipolar II Disorder. Subjects will need to visit the study doctor up to 8 times over a period of 9 weeks.

During the study period, subjects will be receiving a treatment with Quetiapine XR. The starting dose of quetiapine that subjects will receive is 50mg. The response to the treatment of quetiapine will determine whether the study doctor will increase the dosage of the subject's quetiapine. If the study doctor increases the quetiapine during the study, the maximum dosage allowable during the study is 300mg.
