August 29, 2026 updated by: Suven Life Sciences Limited

An Open-Label Study Evaluating the Safety and Efficacy of Ropanicant in Participants With Moderate to Severe Major Depressive Disorder

This is an open-label, parallel-group study to evaluate the safety and efficacy of Ropanicant in participants with moderate to severe Major Depressive Disorder (MDD).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Approximately 36 participants will be randomly assigned to receive Ropanicant either Ropanicant 45 mg once a day (QD), Ropanicant 30 mg twice a day (BID), or Ropanicant 45 mg BID for 2 weeks, in a ratio of 1:1:1 (12 participants in each treatment group). Following a screening period of up to 4 weeks, the participants will be treated for 2 weeks.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Participants must meet the DSM-5 criteria for MDD without psychotic features and diagnosis confirmed by the Mini-International Neuropsychiatric Interview (MINI).
  • Participants with a current major depressive episode of at least 4 weeks of duration prior to the screening visit.
  • Participants must have an MADRS score of ≥25 at the screening and the baseline visits.
  • Participants must have a score of ≥4 on Clinical Global Impression - Severity (CGI-S) Scale at the screening and the baseline visits.

Exclusion Criteria:

  • Participants who meet criteria for treatment-resistant depression during the current major depressive episode, which will be defined as being non-responders (less than 50% of symptom improvement) to 2 or more depression treatment periods of adequate dose and duration as defined by the Massachusetts General Hospital (MGH) Antidepressant Treatment Response Questionnaire (ATRQ).
  • Participants taking antidepressant treatment (SSRIs and SNRIs) or any medication that is contraindicated with the use of monoamine oxidase inhibitors (eg, opioids, stimulants) within 2 weeks (or 5 half-lives, whichever is longer) prior to baseline and until the end of study visit.
  • Participants who do not agree to avoid tyramine rich diet from the start of dosing and until 2 weeks following last study drug administration.
  • Participants who are habitual smokers or using nicotine products.

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
Number of Participants With Treatment-Emergent Adverse Events
Time Frame: From Screening to Day 21
Participants with at least one Treatment-emergent adverse events (TEAEs) reported during the duration of the study.
From Screening to Day 21

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
Montgomery-Åsberg Depression Rating Scale (MADRS) Score
Time Frame: From Baseline to Day 14
Change from the baseline to the MADRS total score. The MADRS is a clinician-rated scale to assess depressive symptoms which consists of 10 items. The time frame for this scale is the past 7 days. Each item is scored on 7-point scale (0 [absence of symptoms] to 6 [severe]). The total score is the sum of 10 items and can take range from 0 to 60. A higher score represents a higher severity of the level of depression.
From Baseline to Day 14
