Multi-Omic, Clinomic and Digitomic Attributes of Major Depression for Integrative Analytics: the MACADAMIA Pilot Study

The purpose of this research is to see if information from blood and data from smartwatches can be combined to help diagnose depression and determine if transitions between active depression and treated depression can be predicted.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Subjects will be recruited from an ongoing cohort study at Mayo Florida "Wearable Augmented Prediction of Burnout in Nurses: A Synergy of Engineering, Bioethics, Nursing and Wellness Sciences" (BROWNIE Study)

Description

Inclusion Criteria:

  • Participated in the BROWNIE study.
  • DSM-5 diagnostic criteria are met for unipolar, non-psychotic MDD (excluding controls).
  • A score of > 10 on the QIDS-C and QIDS-SR (equivalent to 13 or greater on HAM-D17) given that when medication exceeds the effect of placebo in primary care participants have a HAM-D17 >12 (excluding controls).
  • Antidepressant treatment is deemed appropriate by a study clinician (excluding controls).
  • Smart watch wear time is at least 70% during their participation in the BROWNIE study.

Exclusion Criteria:

  • Subjects with medical contraindications that preclude treatment with study drugs will be excluded.
  • Patients with schizophrenia, schizoaffective disorder, or who have bipolar I or II disorder (or another specified or unspecified bipolar spectrum disorder) will be excluded because they have a primary psychiatric condition that requires a different initial treatment.
  • Subjects currently on antidepressant medication with subtherapeutic results in terms of depression management will undergo a medication taper and discontinuation prior to initiation of a new study medication. The subject will be closely monitored by the study clinician during the medication taper and discontinuation phase. The medication taper is left up to the study clinician's discretion. Study subjects who cannot be safely tapered from their medication or experience adverse effects during the taper will be excluded from the study.
  • Subjects who have an active substance use disorder will be excluded. An active substance use disorder will be defined as meeting DSM-5 diagnostic criteria for any active substance use disorder. Persons meeting DSM-5 diagnostic criteria for a substance use disorder in full remission (>12 months) and a negative urine drug of abuse screen at the screening visit or before the baseline study visit will be considered eligible. Persons with a positive urine drug of abuse screen may participate in the study if they do not meet DSM-5 diagnostic criteria for a substance use disorder.
  • Subjects unable to give informed consent or who are unwilling or unable to comply with study requirements are excluded.
  • Pregnant subjects will be excluded.
  • Subjects who are currently breastfeeding and who plan to continue breastfeeding will be excluded.
  • Subjects who are psychiatrically hospitalized or in a mental health crisis requiring urgent care or psychiatric hospitalization.
  • Study subjects currently on antipsychotic medications (e.g., typical, and atypical antipsychotic drugs) taken for primary psychotic illness or affective psychosis will be excluded.
  • Study subjects taking mood stabilizing agents (e.g., lithium, carbamazepine, valproate, lamotrigine, gabapentin, or other anticonvulsants) taken specifically for bipolar spectrum disorders are not eligible for participation.

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Non-depressed controls
Subjects without depression will fill out questionnaires about their general health and wellbeing, quality of life, mental health, emotional health, suicide risk, support system, and childhood experiences. Smartwatch data will also be collected to monitor step count, sleep quality, heart rate (resting and active), and activity rates.
Antidepressant-treated adults
Subjects diagnosed with depression will fill out questionnaires about their general health and wellbeing, quality of life, mental health, emotional health, suicide risk, support system, and childhood experiences. Smartwatch data will also be collected to monitor step count, sleep quality, heart rate (resting and active), and activity rates.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Quick Inventory of Depressive Symptoms-Clinician Rated (QIDS-CR) scale
Time Frame: Baseline, 4 weeks, and 8 weeks
The Quick Inventory of Depressive Symptoms-Clinician Rated is used for rating the severity of depressive symptoms. Possible scores range from 0 to 27, with higher scores indicating greater severity of depression.
Baseline, 4 weeks, and 8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Hamilton Depression Rating Scale
Time Frame: Baseline, 4 weeks, and 8 weeks
The Hamilton Depression Rating Scale is used for rating the severity of depressive symptoms. Possible scores range from 0 to 50, with higher scores indicating greater severity of depression.
Baseline, 4 weeks, and 8 weeks

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 2, 2023

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
