Epidemiologic, comorbidity, cost-of illness, and mortality studies have reported dramatic illness-associated morbidity and premature mortality in bipolar patients. The efficacy and safety of antidepressant drug treatment in BD is the subject of long-standing debate based on a scientific literature that is limited and inconsistent. The evidence base for the use of antidepressant drugs in BD is strikingly weak, and there is insufficient evidence for treatment benefits with antidepressants combined with mood stabilizers. The need to develop new agents for the treatment of depression, and in particular bipolar depression, with better efficacy and/or tolerability, remains unmet. In the past years there has been increasing interest in the health benefits of supplemental and/or dietary substances in the treatment and prevention of depression. The disaccharide trehalose protects cells from hypoxic and anoxic injury and suppresses protein aggregation. In vivo studies with trehalose show cellular and behavioural beneficial effects in animal models of neurodegenerative diseases. Moreover, trehalose was shown to enhance autophagy, a process that had been recently suggested to be involved in the therapeutic action of antidepressant and mood-stabilizing drugs. In fact, trehalose may have antidepressant-like properties and that the trehalose induced behavioral changes are possibly related to trehalose effects to enhance autophagy. Furthermore, preliminary data indicates that trehalose also augments lithium effects in animal models (mice). Based on this hypothesis, this project aims to conduct a study to assess the efficacy and tolerability of trehalose as adjunctive treatment to lithium in bipolar depression.', 'detailedDescription': 'This is an investigator-initiated parallel group pilot study. All patients will give a signed informed consent prior to initiation of any study procedure.\n\nStudy setting: This unicentric pilot study will be carried out at the Bipolar Disorder Programme of the Hospital Clinic, University of Barcelona. Over 700 Bipolar Disorder patients are currently treated by Bipolar Disorders Program of the Hospital Clinic and University of Barcelona, a tertiary center providing integrated care for patients from a specific catchment area as well as difficult-to-treat bipolar patients derived from all over Spain, as already described elsewhere.\n\nPatients are considered to be enrolled in the study when they sign the informed consent. Patients are considered to be randomized when they are assigned to receive either trehalose or maltose. It is expected that at least 60 patients will be randomly assigned in a 1:1 ratio of trehalose 70g to placebo (maltose 70g). Patients will receive no economic compensation for their participation in the study.\n\nPatients will be evaluated at baseline and at weeks 2, 4 and 6. At baseline, patients will receive explanations regarding the study; after signing the informed consent patients will be interviewed by the study psychiatrist and will be administered the study scales M.I.N.I. International Neuropsychiatric Interview-Plus (MINI-Plus), Montgomery-Asberg Depression Rating Scale (MADRS), Hamilton Rating scale for Depression (HAMD), Clinical Global Impression-Bipolar Disorder (CGI-BP), World Health Organization-well being (WHO-wb), Functioning Assessment Short Test (FAST), Cognitive complaints in bipolar disorder rating assessment (COBRA). Furthermore, patients will undergo routine blood analysis including glycaemia, thyroid function (T3, T4, TSH) as well as lithaemia, at baseline and at week 6. At weeks 2 and 4 patients will be administered MADRS, HAMD, CGI-BP, WHO-wb and FAST scales, and eventual side effects will be recorded. At week 6, patients will be interviewed and MADRS, HAMD, CGI-BP, and FAST and will be administered and side effects recorded. At the final visit (week 6), patients will undergo a clinical interview, followed by administration of MADRS, CGI-BP, WHO-wb, COBRA and FAST scales. Full blood analysis will be performed.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Bipolar I and II patients aged between 18 and 65.\n* Bipolar disorder type I or II and a current major depressive episode (Montgomery-Asberg Depression Rating Scale (MADRS) ≥18.\n* Clinical Global Impression-Bipolar version (CGI-BP)≥4.\n* All patients need to be receiving lithium at a steady dose (0.5-1.2 mmol/L) during at least 2 weeks prior to the study.\n* Other mood stabilizers added to lithium are permitted but at steady dose during at least 2 weeks prior to the study.\n* Other psychopharmacological treatments should be at stable dose 2 weeks prior to the study.\n\nExclusion Criteria:\n\n* Exclusion criteria will be the presence of psychotic features, severe suicidal ideation (score of ≥5 on item 10 of MADRS).\n* A severe personality disorder suggesting noncompliance.\n* Diabetes Mellitus, any severe neurologic or other somatic illness and the use of somatic medication that could influence the mood.'}, 'identificationModule': {'nctId': 'NCT02800161', 'briefTitle': 'Trehalose as add-on Therapy in Bipolar Depression', 'organization': {'class': 'OTHER_GOV', 'fullName': 'Consorcio Centro de Investigación Biomédica en Red (CIBER)'}, 'officialTitle': 'Trehalose as add-on Therapy in Bipolar Depression', 'orgStudyIdInfo': {'id': '#14t-012'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Trehalose', 'description': 'Trehalose 70g/die', 'interventionNames': ['Drug: Trehalose']}, {'type': 'PLACEBO_COMPARATOR', 'label': 'Placebo', 'description': 'Maltose 70g/die', 'interventionNames': ['Drug: Maltose']}], 'interventions': [{'name': 'Trehalose', 'type': 'DRUG', 'description': 'Trehalose 70g/die', 'armGroupLabels': ['Trehalose']}, {'name': 'Maltose', 'type': 'DRUG', 'description': 'Maltose 70g/die', 'armGroupLabels': ['Placebo']}]}, 'contactsLocationsModule': {'locations': [{'zip': '08036', 'city': 'Barcelona', 'country': 'Spain', 'facility': 'Hospital Clinic of Barcelona', 'geoPoint': {'lat': 41.38879, 'lon': 2.15899}}], 'overallOfficials': [{'name': 'Eduard Vieta, MD,PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Principal Investigator CIBER'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'YES'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Consorcio Centro de Investigación Biomédica en Red (CIBER)', 'class': 'OTHER_GOV'}, 'collaborators': [{'name': 'Stanley Medical Research Institute', 'class': 'OTHER'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
