NCT06002100

Brief Summary

The purpose of the current study is to perform a unified, homogeneous data collection protocol that includes a large cohort of patients undergoing different treatment options for Major Depressive Disorder (MDD) as an avenue for investigating optimal biomarkers for depression treatments on an individual patient level.

Outcome Measures

Primary Outcomes (4)

  • Brain hemodynamic activity with TD-fNIRS

    This includes changes in the concentration of oxygenated and deoxygenated hemoglobin as measured by the change in light absorption.

    Approximately 30 minutes during each study visit

  • Optical properties of the brain with TD-fNIRS

    This measures how much light is absorbed at different points on the head.

    Approximately 30 minutes during each study visit

  • Physiological features with TD-fNIRS

    This includes cardiac measures, such as heart rate (HR).

    Approximately 30 minutes during each study visit

  • Physiological features with TD-fNIRS

    This includes cardiac measures, such as heart rate variability (HRV).

    Approximately 30 minutes during each study visit

Secondary Outcomes (6)

  • Montgomery-Ă…sberg Depression Rating Scale (MADRS)

    At baseline and closeout, up to 3 months

  • Patient Health Questionnaire (PHQ-9)

    From baseline to closeout, up to 3 months

  • General Anxiety Disorder (GAD-7)

    At baseline and closeout, up to 3 months

  • Snaith-Hamilton Pleasure Scale (SHAPS)

    At baseline and closeout, up to 3 months

  • World Health Organization Quality of Life (WHOQOL-BREF)

    At baseline and closeout, up to 3 months

  • +1 more secondary outcomes

Study Arms (4)

Ketamine

Adult participants starting ketamine treatment for depression at a participating clinic. fNIRS measurements using Kernel Flow2 will be taken at a pre-treatment, early-treatment, and post-treatment visit. No clinical decisions will be made based on the data acquired for this study, and participation in the study has no influence on treatment decisions (including dosage form, frequency, and duration).

Other: fNIRS measurement

SPRAVATO

Adult participants starting SPRAVATO treatment for depression at a participating clinic. fNIRS measurements using Kernel Flow2 will be taken at a pre-treatment, early-treatment, and post-treatment visit. No clinical decisions will be made based on the data acquired for this study, and participation in the study has no influence on treatment decisions (including dosage form, frequency, and duration).

Other: fNIRS measurement

TMS

Adult participants starting TMS treatment for depression at a participating clinic. fNIRS measurements using Kernel Flow2 will be taken at a pre-treatment, early-treatment, and post-treatment visit. No clinical decisions will be made based on the data acquired for this study, and participation in the study has no influence on treatment decisions (including dosage form, frequency, and duration).

Other: fNIRS measurement

Antidepressants

Adult participants starting antidepressant treatment for depression at a participating clinic. fNIRS measurements using Kernel Flow2 will be taken at a pre-treatment and short-term efficacy visit. No clinical decisions will be made based on the data acquired for this study, and participation in the study has no influence on treatment decisions (including dosage form, frequency, and duration).

Other: fNIRS measurement

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adult participants seeking treatment for depression at a participating clinic/study site. Separate cohorts of participants will be enrolled depending on the treatment they have been prescribed. No clinical decisions will be made based on the data acquired for this study, and participation in the study has no influence on treatment decisions.

You may qualify if:

  • Ketamine cohort
  • Adult between the ages of 18 - 65, inclusive at time of enrollment
  • Primary diagnosis of MDD as defined by DSM-5
  • Determined by clinic to be eligible for ketamine treatment and agrees to receive ketamine treatment
  • Agrees to start ketamine treatment in conjunction with study participation to capture pre-treatment measurements accurately
  • Has not received a ketamine treatment course in the past 12 months
  • Has not received a TMS treatment course in the past 3 months
  • Ability to consent for themselves
  • Fluency in English (speaking and reading)
  • SPRAVATO cohort
  • Adult between the ages of 18 - 75, inclusive at time of enrollment
  • Primary diagnosis of MDD as defined by DSM-5
  • Determined by clinic to be eligible for SPRAVATO treatment and agrees to receive SPRAVATO treatment
  • Agrees to start SPRAVATO treatment in conjunction with study participation to capture pre-treatment measurements accurately
  • Has not received a ketamine or SPRAVATO treatment course in the past 12 months
  • +21 more criteria

You may not qualify if:

  • Is or may be pregnant (for participant of childbearing potential \[POCBP\]), even if they have been cleared to receive the depression treatment
  • Unable or unwilling to wear the TD-fNIRS headset
  • Has had ECT in the past 3 months
  • Major visual or auditory deficits that would prevent study task completion
  • Hospitalizations and/or unstable health/medical condition/treatment in the last 30 days
  • Major medical illnesses and psychiatric conditions including:
  • Alzheimer's/Mild Cognitive Impairment
  • Parkinson's disease
  • Motor neuron diseases
  • Multiple Sclerosis
  • Brain Tumor
  • Stroke
  • Encephalitis
  • Meningitis
  • Epilepsy
  • +4 more criteria
