No
If Stopped, Why?:
The reason the study was withdrawn was due to lack of funds In addition the PI is moving to a different institution and it would not be feasible to proceed with the study under these circumstances

Brief Summary:
This study will assess the safety and tolerability of Candesartan when used in patients with Bipolar Disorder in addition to their medication treatment
Detailed Description:
Pharmacological options for the treatment of Bipolar disorder BD are limited and a large proportion of patients does not show adequate response to treatment especially in the case of bipolar depression It has been hypothesized that dysfunctions in the renin-angiotensin system RAS may be involved in the pathophysiology of BD We propose a double-blind randomized placebo-controlled cross-over proof-of-concept trial to investigate the effects of candesartan an angiotensin-II receptor antagonist capable to cross the blood-brain barrier as an adjunctive agent in the treatment of bipolar depression Bipolar patients on a depressive episode will be randomly assigned to undergo two consecutive 4-week treatment periods with either candesartan 4 mg daily or placebo in a crossover study At the beginning of each treatment period participants will complete a resting-state functional MRI scan to be performed 15 hours after the first dose of the study medication Subjects will be followed weekly and the Montgomery-Asberg Depression Rating Scale MADRS will be adopted as the primary outcome measure Response will be defined as a decrease equal or higher than 50 in the MADRS score from the time of study entry to the 4th week of each treatment period Possible associations between changes in brain connectivity measured through resting state functional MRI and subsequent response to treatment will also be analyzed
