Can a Three-Day pill ease postpartum depression?
NCT ID NCT07721961
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This phase 3 trial tests whether an experimental drug called MI078 can safely reduce symptoms of postpartum depression in new mothers. About 200 women aged 18 to 45 with a recent diagnosis of major depression linked to childbirth will receive either MI078 capsules or a placebo for three days. Researchers will measure changes in depression scores using standard rating scales to see if the drug offers meaningful relief.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- an experimental drug called MI078
- What this could lead to
- If it works, this could offer a new, fast-acting treatment option for postpartum depression, a condition that affects many new mothers.
- What could go wrong
- This is an early-phase trial with only 200 participants, so results may not apply to everyone. The drug's safety and effectiveness are still unproven, and side effects are possible.

Exclusion Criteria: * Currently meeting diagnostic criteria for other DSM-5 psychiatric disorders, as assessed by the investigator. * History of bipolar disorder, schizophrenia, and/or schizoaffective disorder. * Reduction in HAM-D17 total score from screening to baseline ≥25%. * Presence of suicidal ideation/intent, or HAM-D17 Item 3 (suicide) score \>3, or a "yes" response to Item 4 or 5 of the Columbia-Suicide Severity Rating Scale (C-SSRS) for suicidal ideation in the past 6 months at baseline, or a history of suicidal behavior within 1 year. * Meeting diagnostic criteria for treatment-resistant depression. * Continuous use of therapeutic doses of antidepressants for more than 14 days during the current episode. * Discontinuation of psychotropic medications for less than 5 half-lives prior to the first dose of study drug. * Need for concomitant use of other psychoactive drugs during the treatment period, including antidepressants, antipsychotics, mood stabilizers, and sedative-hypnotics (excluding non-benzodiazepines). * Discontinuation of strong CYP3A4 inducers or inhibitors for less than 5 half-lives prior to the first dose of study drug. * Receipt of systematic psychotherapy (e.g., interpersonal therapy, psychodynamic therapy, cognitive-behavioral therapy) or psychiatric-related acupuncture within 1 week prior to the first dose, or planned receipt of such treatments during the trial. * Receipt of other physical treatments for psychiatric disorders (e.g., modified electroconvulsive therapy, transcranial magnetic stimulation, psychiatric-related laser therapy, vagus nerve stimulation, deep brain stimulation, light therapy) within 1 month prior to screening. * Presence of severe or unstable cardiovascular, hepatic, renal, hematological, endocrine (e.g., uncontrolled hyper- or hypothyroidism), neurological (e.g., epilepsy, Parkinson's disease, multiple sclerosis, Huntington's disease, history of seizure disorder \[except single febrile seizure in childhood\]), gastrointestinal (e.g., history of gastrointestinal disease or surgery that may interfere with drug absorption, distribution, metabolism, or excretion), or other systemic or organ diseases, as judged by the investigator. * History of malignancy within 1 year prior to screening. * Participation in another drug trial within 3 months prior to screening, or participation in a medical device trial within 1 month prior to screening (defined as having received investigational drug or device treatment). * Major surgery (excluding cesarean section) within 1 month prior to screening, or planned surgery during the trial period. * History of hypersensitivity (allergy to at least 2 substances) or known allergy to progesterone. * Positive pregnancy test at screening or baseline (for participants who are 4 weeks postpartum, a positive result requires retesting), or unwillingness to use effective contraception throughout the trial and for at least 3 months after the last dose of study drug, or plans for oocyte donation during this period. * Clinically significant abnormal 12-lead electrocardiogram (ECG) or laboratory findings at screening or baseline that, in the investigator's opinion, may affect the trial, including but not limited to alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \>2× upper limit of normal (ULN), or serum creatinine \>1.5× ULN. * Currently breastfeeding and unwilling to discontinue breastfeeding during the treatment period and for 7 days after the last dose. * Any physical/psychological illness or condition that, in the investigator's opinion, may increase the risk of the trial, affect compliance with the protocol, or interfere with the completion of the study, or any other condition that the investigator deems unsuitable for participation in this trial.
