Study summary

The goal of this observational study is to demonstrate effectiveness in the treatment of Major Depressive Disorder

The primary objective is to assess the effectiveness in the treatment of Major Depressive Disorder using the CGI-I at the end of the treatment

Participants will receive 10 treatments per day for 5 days (M-F) of SAINT®

Read the detailed description

This is a prospective, multi-center, open-label study.

Up to 1000 adult subjects, in a major depressive episode, who have failed to receive satisfactory improvement from a prior antidepressant medication in the current episode, are eligible to participate in this study if they are deemed to be appropriate candidates for TMS.

Overall study duration is expected to be approximately 4 years. The study duration per subject is anticipated to be approximately 1 year.

Hypothesis: The SAINT® Neuromodulation System will demonstrate effectiveness in the treatment of MDD as measured by CGI-I at the end of the treatment (cessation of stimulation).

Study population

Participants who fulfill all the inclusion criteria and none of the exclusion criteria will be enrolled into the study. Each participant will read and sign the IRB approved informed consent form prior to any screening or study procedures being performed. This open-label study involves an evaluation of the safety and effectiveness of an acute course of the SAINT® NMS.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Adult males or females, 18 and older, who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.
  2. Confirmed primary clinical diagnosis of major depressive disorder (MDD) without psychotic features consistent with criteria.
  3. No medical conditions that would preclude the safe use of TMS.
  4. Primary psychiatrist has determined TMS to be an appropriate clinical option.
  5. Able to provide consent and comply with all study requirements.
  6. Negative pregnancy test at the intended time of SAINT™ 5-day acute course treatment and agreement to use effective during SAINT® acute therapy.

Exclusion criteria

Exclusion Criteria:

  1. Have any to TMS (section 2 User Manual).
  2. Have any contraindication to receiving an MRI
  3. Participants with an abnormal brain MRI as determined by PI, study physician or designee.
  4. Deemed by the PI, study physician or designee to be a high risk of suicide or has made a suicide attempt within the last 6 months.
  5. Treatment dose with cortical depth adjustment is greater than 120% motor threshold and cannot be completed.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Groups and cohorts

  • SAINT® Stimulation

    All participants will receive 10 treatments per day for 5 days (M-F) of SAINT® stimulation therapy.

    Device: SAINT® Neuromodulation System (NMS)

Interventions

  • DeviceSAINT® Neuromodulation System (NMS)

    The SAINT® NMS utilizes a type of accelerated iTBS delivered to a personalized treatment target derived from a functional MRI scan. SAINT® was designed to optimize the individual patient response to treatment. This novel approach to TMS is accomplished by focusing on three critical aspects of the treatment that drive effect. These aspects are personalized stimulation target, total course dose of stimulation, and neurophysiologically relevant stimulation pattern.

    Also known as: TMS

What researchers measure

Primary outcomes

  1. Mean Clinical Global Impression Improvement Scale (CGI-I) score at the end of treatment (Day 5 SAINT® therapy)

    Clinical Global Impression-Improvement (CGI-I) score is based on a scale from zero (0) - Not Assessed to seven (7) Very Much Worse with lower scores showing improvement and higher scores showing little or no improvement.

    Time frame: End of Stimulation Day 5

Secondary outcomes

  1. Montgomery-Asberg Depression Rating Scale (MADRS) score change from baseline to cessation of stimulation in comparison with bioimaging assessments MADRS score change from baseline to cessation of stimulation in comparison with bioimaging assessments

    The rating is based on a clinical interview. Questions are asked using scales from zero (0) to six (6) with lower scores showing a better outcome and higher scores showing a worse outcome

    Time frame: Baseline to End Stimulation Day 5

  2. Cambridge Brain Science Tools assessment score change in comparison with change in MADRS scores from baseline to cessation of stimulation

    Assess aspects of cognition including reasoning, memory, attention and verbal ability on an online platform. Scores are automatically calculated on a scale from zero (0) to one hundred (100) and zero (0) to negative one hundred (-100) with positive numbers being associated with "Best" and negative numbers being associated with "Worst"

    Time frame: Baseline to End of Stimulation Day 5

  3. To test the durability of the antidepressant effect by assessing the Clinical Global Impression Severity Scale (CGI-S) after cessation of stimulation

    The Clinical Global Impression-Severity (CGI-S) is a brief clinician assessment that rates the severity of the patient's illness at the time of assessment, relative to the clinician's past experience with patients who have the same diagnosis. Score is based on a scale from zero (0) - Not Assessed to seven (7) Very Much Worse with lower scores showing improvement and higher scores showing little or no improvement.

    Time frame: 3, 6, 9, 12 month follow up visit

Other outcomes

  1. Safety - Adverse Event Reporting assessment for causality and severity

    Any untoward medical occurrence in a participant treated with an investigational device, without regard to the possibility of a causal relationship with this treatment. Adverse events will be recorded and followed through all follow-up visits

    Time frame: Consent through 12 month follow up visit

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Apr 2023 (actual). Primary completion is estimated for Oct 2026, 42 months after the start.

Of 29 industry-sponsored observational studies under Depressive Disorder, Major, half reached primary completion within 21 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 33. This study's planned 42 months is above that.

Counting every sponsor, half of 150 studies reached it within 38 months; a quarter within 21 and three quarters within 67.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 24, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
