This will be an open-label, uncontrolled study which will enroll subjects completing Study 31-08-250 and new subjects. The treatment history of subjects prior to enrollment in the open-label study will vary according to the design of the pivotal double-blind study (i.e 31-08-250).
This open-label study will be comprised of phases similar to the pivotal double-blind study (i.e. Study 250): a screening phase (if applicable), a conversion phase (Phase A, if applicable), an oral stabilization phase (Phase B, if applicable), and an IM depot open-label maintenance phase (Phase C). Phase C will be a minimum of 28 weeks up to a 52-week treatment period with a 4 week follow up period.
During Phase C (the open-label maintenance phase) rescue medication will be allowed for subjects who do not meet stability criteria. This analysis focuses on Phase C due to ClinicalTrials.gov system limitations.
