Digital Phenotypes for Predicting Depression_Validation

This 12-month, single-site prospective observational study will prospectively monitor the recurrence of mood episodes while continuously collecting passive digital phenotypes in individuals with and without mood disorders. A total of 200 adults will be enrolled, including 100 patients with major depressive disorder or bipolar I/II disorder and 100 healthy control participants. Participants will complete five clinical assessments at 3-month intervals and will continuously wear a consumer wearable device and use the My Mental HERO smartphone application for passive sensing and daily mood recording. Structured clinical interviews will identify the occurrence, subtype, and day-level onset and offset of mood episodes during follow-up. The study will examine longitudinal digital phenotypes associated with mood states and subsequent mood episode onset. It is designed to provide an independent validation dataset for digital phenotypes and prediction models developed in the preceding MentalHERO prospective observational cohort (ClinicalTrials.gov Identifier: NCT07151846). Because the two cohorts follow closely aligned study protocols and assessment schedules, data from both cohorts may also be pooled for secondary analyses where appropriate.

NMDA Receptor Modulation for the Treatment of Bipolar I Disorder

At present, the treatment of Bipolar I disorder (BD-I), especially its depressive episode (bipolar depression), is still limited, because there is no effective treatment for the associated cognitive impairment and perceived stress. NMDA receptor (NMDAR) dysfunction is associated with BD-I, particularly its cognitive impairment and perceived stress. This study aims to examine the efficacy and safety of an NMDA enhancer (NMDAE) in the treatment of cognitive impairment and perceived stress in the patients with bipolar depression.

Study of Oral ABBV-932 to Assess Adverse Events and Change in Disease Activity in Adult Participants With Bipolar I or II Disorder

Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population in the United States. This study will assess how safe and effective ABBV-932 is in treating participants with bipolar I or II disorder. ABBV-932 is an investigational drug being developed for the treatment of depressive episodes in adult participants with bipolar I or II disorder. Study doctors put participants in 1 of 4 groups, called treatment arms. There is a 1 in 4 chance that a participant will be assigned to placebo. Around 160 adult participants with bipolar I or II disorder will be enrolled in approximately 40 sites worldwide. Participants will receive oral capsules of ABBV-932 or matching placebo once daily for 6 weeks. The treatment period will be followed by a safety follow-up (SFU) period for 4 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular weekly visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Safety and Feasibility of DBS for Bipolar Depression

This study addresses a critical unmet need in the treatment of bipolar disorder by investigating whether Subcallosal Cingulate (SCC) Deep Brain Stimulation (DBS) can safely and effectively treat treatment-resistant bipolar depression without inducing manic switches. The researchers propose to accomplish this by incorporating monitoring of the SCC local field potentials (LFP) for depression tracking and amygdala LFP monitoring for mania prediction while treating Bipolar I patients with SCC DBS Stimulation. This approach could establish a new paradigm for personalized neuromodulation therapy that uses real-time neural monitoring to optimize outcomes while minimizing risks. By incorporating bilateral, dual-site LFP monitoring from both the SCC and amygdala, this research will allow the researchers to assess the therapeutic efficacy of continuous SCC-DBS and develop novel safety biomarkers that could transform the clinical management of DBS therapy in psychiatry. The findings will have immediate implications for clinical practice and will advance the study team's fundamental understanding of the neural circuits underlying mood regulation and dysregulation in bipolar disorder.

A Study to Assess Change in Disease Activity and Adverse Events (AEs) With Cariprazine in the Treatment of Depressive Episodes in Pediatric Participants Participants (10 to 17 Years of Age) With Bipolar I Disorder.

Bipolar disorder is a severe chronic mood disorder that affects up to 4% of the adult population and 1.8% of the pediatric population in the United States. The treatment of the depressive episodes of bipolar disorder in the pediatric population has not been as widely studied as the treatment of depressive episodes in bipolar disorder in adults, therefore pharmacotherapeutic options are limited. Given the change in disease state and safety demonstrated in adults with depressive episodes associated with bipolar I disorder, the purpose of this study is to evaluate the change in disease state and safety of cariprazine in the treatment of depressive episodes associated with bipolar I disorder in the pediatric population. Cariprazine is an approved drug for the treatment of depressive episodes in adult participants with bipolar I disorder. Study doctors put participants in 1 of 2 groups, called treatment arms. There is a 1 in 2 chance that a participant will be assigned to placebo. Around 380 Participants ages 10-17 years with bipolar I disorder will be enrolled in approximately 60 sites worldwide. Participants receiving the study drug will receive Dose A or B of Cariprazine based on age and weight. At Week 3, participants with insufficient response will have their dose increased to Dose B or Dose C, while participants with sufficient response will continue receiving the Dose A or B for the remainder of the treatment period. The treatment period will be followed by a safety follow-up (SFU) period for 4 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular weekly visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

SYNCED - SYNChronized Eating in Bipolar Depression Study

Bipolar disorders (BD) are a group of complex disorders that impact mood, behaviour and cognition and are known to cause significant suffering and impairment. Circadian rhythm (your internal day/night "clock") disruption, which can involve changes in sleep-wake cycles, frequently occurs in BD. Both depression and mania are accompanied by circadian disruption. These disruptions are hypothesized to lead to mood worsening, metabolic dysfunction and inflammation. If circadian dysfunction plays a significant role in the symptoms and trajectory of BD, then treatment approaches that target these functions may lead to better outcomes. One such approach is dietary interventions. Time restricted eating (TRE) is a dietary tool that restricts the eating to an 8-12 hour window, without changing diet quality or caloric intake. Studies involving time restricted eating have been done in other conditions with promising results. There have been no studies done for mood disorders in general or bipolar disorder specifically. In this proposal, the investigators will assess two dietary interventions (TRE and nutritional counselling) to examine how TRE may represent a safe and viable adjunct to traditional treatments. The investigators aim to compare TRE with nutritional counselling, while all participants continue to receive usual care. Participants will receive support from a registered dietician and will be instructed on dietary habits. Half of participants will receive nutritional counselling and half will be asked to do TRE. Those in the TRE group will be asked to select a 10-hour window to consume all food and non-water beverages for the 8-week period. Participants will be asked to complete a screening visit to determine eligibility, and then will complete questionnaires at baseline, week 4 and week 8 examining symptoms of their illness and cognition. Participants will also provide a blood sample at baseline and week 8 for standard biochemistry tests, pregnancy testing (if applicable), and to examine inflammatory markers. Participants will also wear an actigraphy watch which provides wireless continuous monitoring of movements and ambient light. The primary outcome is feasibility and acceptability (do people agree to participate, complete the study, and follow the intervention; what do they think of the intervention). Secondary outcomes include changes in depression, anxiety, sleep, and cognition. Exploratory outcomes include inflammatory markers and circadian disruption.
