About this study

Official title: A Phase 3, Multicenter, Randomized, Double-Blind, Placebo- Controlled Study to Assess the Efficacy and Safety of REL-1017 as Adjunctive Treatment of Major Depressive Disorder (The RELIANCE-II Study)

This is an outpatient, 2-arm, Phase 3, multicenter, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of REL-1017 once daily (QD) as an adjunctive treatment of Major Depressive Disorder. Study participants will continue to take their current antidepressant therapy in addition to the study drug or placebo for the duration of the treatment period.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline to Day 28 in MADRS Total Score

    Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score. The MADRS is a clinician-rated scale that assesses the severity of depressive symptoms. The total score is calculated as the sum of 10 items, each scored from 0 to 6, resulting in a total score range of 0 to 60. Lower scores indicate less severe depressive symptoms and a better outcome, whereas higher scores indicate more severe depressive symptoms and a worse outcome. The outcome measure reports the change in MADRS total score from Baseline to Day 28. Change was calculated as Day 28 score minus Baseline score.

    Measured: Baseline and Day 28

Secondary outcomes (4)
  1. Change From Baseline to Day 7 in MADRS Total Score

    Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score. The MADRS is a clinician-rated scale that assesses the severity of depressive symptoms. The total score is calculated as the sum of 10 items, each scored from 0 to 6, resulting in a total score range of 0 to 60. Lower scores indicate less severe depressive symptoms and a better outcome, whereas higher scores indicate more severe depressive symptoms and a worse outcome. The outcome measure reports the change in MADRS total score from Baseline to Day 7. Change was calculated as Day 7 score minus Baseline score.

    Measured: Day 7

  2. Change From Baseline to Day 28 in Clinical Global Impression-Severity (CGI-S) Score

    Clinical Global Impression-Severity (CGI-S) is a clinician-rated assessment of illness severity. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients). Lower scores indicate less severe illness and a better outcome, whereas higher scores indicate more severe illness and a worse outcome. The outcome measure reports the change in CGI-S score from Baseline to Day 28. Change was calculated as Day 28 score minus Baseline score

    Measured: Day 28

  3. MADRS10 Remission Rate at Day 28

    Remission was defined as a Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score ≤10 at Day 28. The MADRS total score ranges from 0 to 60, with lower scores indicating less severe depressive symptoms and a better outcome.

    Measured: Day 28

  4. MADRS10 Response Rate at Day 28

    Response was defined as a ≥50% reduction from Baseline in Montgomery-Åsberg Depression Rating Scale (MADRS) Total Score. The MADRS total score ranges from 0 to 60, with lower scores indicating less severe depressive symptoms and a better outcome.

    Measured: Day 28

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing REL-1017 in people with Major Depressive Disorder and Depression, run by Levomecor Inc. at 70 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 10 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 70 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Jul 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline to Day 28 in MADRS Total Score (time frame: Baseline and Day 28). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2026.
