-
In October 2026, Alkermes announced the initiation of a Phase II clinical trial evaluating ALKS 7290, an investigational oral orexin-2 receptor agonist, as an adjunctive treatment to antidepressants in adults with MDD. The randomized, double-blind, placebo-controlled study is expected to enroll approximately 180 participants and assess safety, tolerability, and changes in depression symptoms using MADRS scores. The trial is registered as NCT07901179.
-
In September 2026, Definium Therapeutics announced that the US FDA granted Breakthrough Therapy Designation to DT120, an investigational lysergide oral disintegrating tablet, for the treatment of MDD. The designation followed positive Phase III Emerge trial results, which demonstrated an 8.1-point placebo-adjusted improvement in MADRS scores at Week 6, with sustained benefits through Week 12.
-
In September 2026, Johnson & Johnson reported that its Phase II MOONLIGHT-1 study of JNJ-5120/PIPE-307 failed to meet its primary endpoint of improving depressive symptoms, measured using MADRS scores, at Day 5. Although the investigational therapy was generally well tolerated, the outcome represented a setback for its development in MDD.
-
In September 2026, COMPASS Pathways reported 52-week open-label extension findings from its Phase III COMP005 study, evaluating the longer-term effects of additional COMP360 dosing in patients with treatment-resistant depression. The findings provided further clinical evidence regarding the durability of treatment response.
-
In August 2026, COMPASS Pathways continued advancing its Phase III COMP006 clinical trial of COMP360, a synthetic psilocybin formulation, in patients with treatment-resistant depression (TRD). The study evaluates the efficacy, safety, and tolerability of repeated COMP360 administration. The trial registry reported the study as active but not recruiting.
-
In July 2026, Helus Pharma announced completion of enrollment in its Phase III APPROACH study evaluating HLP003 as an adjunctive treatment for moderate-to-severe MDD in patients with inadequate responses to existing antidepressants. The company expected topline results in Q4 2026. HLP003 had previously received FDA Breakthrough Therapy Designation for MDD.
-
In June 2026, Definium Therapeutics announced positive topline results from its Phase III Emerge study evaluating DT120 in MDD. A single 100 µg dose demonstrated a statistically significant 8.1-point placebo-adjusted improvement in MADRS scores at Week 6 (p less than 0.0001). The findings supported further development of DT120 as a potential treatment for MDD.
-
In April 2025, Mind Medicine (MindMed) Inc. (NASDAQ: MNMD), a clinical-stage biopharmaceutical company focused on developing innovative treatments for brain health disorders, has announced that the first patient has been dosed in its Phase 3 Emerge study. The study is evaluating MM120 ODT, a proprietary, pharmaceutically optimized form of LSD, for the treatment of major depressive disorder (MDD). The Emerge trial will assess the efficacy and safety of MM120 ODT 100 µg compared to a placebo and is expected to enroll approximately 140 participants in the United States. This marks the third Phase 3 study for MM120 ODT, following the ongoing Voyage and Panorama studies in generalized anxiety disorder (GAD).
-
In March 2025, Johnson & Johnson (J&J) has decided to discontinue its Phase III major depressive disorder (MDD) program for aticaprant, citing “insufficient efficacy in the target population.” The VENTURA program, which tested the experimental drug as an adjunctive treatment for MDD, consisted of five Phase III trials. Despite the lack of efficacy, the company stated that aticaprant was found to be safe and well-tolerated throughout the program. Complete data from the VENTURA trials will be shared at an upcoming medical meeting.
-
In January 2025, HMNC Brain Health (HMNC) has completed the randomization process in its placebo-controlled Phase IIb OLIVE trial for BH-200, a vasopressin V1b receptor antagonist, aimed at treating major depressive disorder (MDD). The trial, designed to evaluate the safety and efficacy of the therapy alongside a predictive companion diagnostic, involves 338 outpatients. It is part of the company’s Nelivabon program, which targets MDD in patients with HPA-axis dysfunction, a condition that affects about 30% of all MDD cases.
Major Depressive Disorder Overview
Major Depressive Disorder (MDD) is a common and serious mental health condition characterized by persistent feelings of sadness, loss of interest or pleasure in daily activities, and changes in mood, sleep, appetite, energy, and concentration. It can significantly affect an individual’s emotional well-being, social relationships, and daily functioning. MDD management typically involves antidepressant medications, psychotherapy, or a combination of both, depending on disease severity and individual patient needs.
