E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is the evaluation of the effects of lithium on mood variability measured using weekly self-reports of manic and depressive symptoms.
Weekly self-rating is used routinely by many patients as part of ongoing self-management of mood by people with bipolar disorder and daily ratings have been used successfully in a number of research studies.
An understanding of the effects of lithium on mood will both inform its use and provide valuable information that will facilitate discovery of more effective and safer treatments.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives involve the use of a range of paradigms to explore the mechanism of action of lithium treatment on: - cognition tasks - neural dynamics using magnetoencephalography (MEG) and magnetic resonance imaging (MRI) - activity levels during wake and sleep periods using device(s) that can be carried or worn under clothing or on a wrist - hormones related to circadian rhythms measured from saliva - gene expression from cheek swabs samples for genes known to be associated with circadian rhythms and lithium treatment - early markers of adverse effects particularly those associated with renal, thyroid and parathyroid function and inflammatory markers.
Results of these assessments will provide valuable information about the mechanism of action of lithium. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Willing and able to give informed consent to participate in the trial • Male or female • Aged 18 or over • Meeting criteria for bipolar disorder • Clinical complaint of significant mood instability • Clinical uncertainty about the prescription of lithium • No clear indication for alternative treatment • Pre-treatment tests including renal, cardiac, thyroid and parathyroid functions acceptable for initiation of treatment with lithium • Willing and able to comply with all trial requirements including mood and behavioural monitoring (True Colours) and MRI and MEG scanning and blood tests (assessed by a psychiatrist). • Willing to allow his/ her General Practitioner and consultant, if appropriate, to be notified of his/her participation in the trial.
|
|
E.4 | Principal exclusion criteria |
• Contraindication(s) to lithium (as documented in the Summary of Product Characteristics for Priadel) • Currently taking any psychotropic drug that cannot be withdrawn (i.e. antidepressant, antipsychotic, mood stabiliser, benzodiazepine, non-benzodiazepine sleeping tablets) including as required (prn) medication • Clinically significant alcohol or substance use • Requiring immediate treatment for an acute mood episode such that placebo would be inappropriate • Female and pregnant, lactating or planning a pregnancy during the course of the trial • Female of child-bearing potential not willing to use effective contraception • Participation in another research trial involving an investigational medicinal product in the past 12 weeks. • Judged to be at significant immediate risk of suicide/self-harm
In addition to the above criteria: • Patients who have a pacemaker, non-MR-compatible metal implant, or any other contraindication for MR or MEG brain scanning will be excluded from the corresponding brain scanning element(s) of Theme 2.
* Patients with a primary diagnosis of bipolar disorder with co-morbid anxiety or borderline personality disorder are not excluded.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome will be a between group comparison of mood symptoms over the randomised period. This will be measured by the True Colours system for self-rating of mood using mobile phones or online forms and by PANAS (Positive and Negative Affect Scale). The True Colours system collects weekly measures of depressive and manic symptoms on validated self-rating scales (the Quick Inventory of Depressive Symptomatology [QIDS-SR6] and the Altman Self Rating Scale for Mania [ARSM]). The PANAS will be completed daily on an iPad. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Symptoms of depression and mania will be reported weekly by participants using validated scales (Quick Inventory of Depressive Symptomatology [QIDS-SR16] and Altman Self-Rating Scale for Mania [ASRM]) throughout the 6-week randomised phase. |
|
E.5.2 | Secondary end point(s) |
Theme 2: Cognitive tests: 1. Cognitive assessments and measures of variability in performance across time and Mood Zoom ratings. Scans: Blood oxygen level dependent signal during rest and cognitive testing; induced and evoked field activity.
Theme 3: Activity tracking when awake and asleep using activity monitoring device(s) and, for participants with a smartphone who agree to installation of apps, the measurement of relative location and frequency and duration of voicecalls and text messages.
Theme 4: Changes in gene expression and in cortisol and melatonin levels.
Theme 5: Changes from baseline 6-weeks in blood test results including those relevent to renal, thyroid and parathyroid function and inflammaotory markers. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Theme 2 will include cogntive tests completed at baseline and repeated at the 4-week visit and short daily tests completed on the iPad. Scans (MRI and MEG) will take place during the fourth week.
Theme 3 activity monitor(s) will be carried throughout the trial.
Theme 4 will involve two 32-hours periods, one pre-randomisation and the other in week 4 when participants will provide cheek swab and saliva samples every 4 hours.
Theme 5 will involve blood tests at baseline and week 6 onlhy for all tests except lithium tests which be completed a 4- and 8-days, 4 weeks and 6 weeks after randomisation (in line with routine care for initiation of lithium). |
