Safety, Tolerability, PK Profile, and Symptom Response of a 7-Day Dosing With 25 mg or 50 mg Daily of REL-1017 in MDD

Completed · Phase 2 · Has a placebo group

Conditions studied: Depressive Disorder, Major, Depressive Disorder, Treatment-Resistant

In brief

This a Phase 2a, multicenter, randomized, double-blind, placebo controlled 3 arm study to assess the safety and tolerability of multiple oral doses of REL-1017 25 mg and 50 mg as adjunctive therapy in the treatment of patients diagnosed with major depressive disorder (MDD). The patients will be adults with MDD who are diagnosed with a current MDE who have experienced an inadequate response to 1 to 3 courses of treatment with an antidepressant medication. This population will provide the opportunity to compare the safety and efficacy effects of treatment with an approved antidepressant in conjunction with REL-1017 versus the effects of an antidepressant alone. This study includes in-patient and out-patient periods.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Males between 18 and 65 years of age, inclusive; and females between 18 and 65 years of age, inclusive, who are >1 year postmenopausal.
• Diagnosed with recurrent MDD as defined by the Diagnostic and Statistical Manual, Fifth Edition (DSM-5), and confirmed by the Mini International Neuropsychiatric Interview, Version 7.0.2 (MINI).
• Diagnosed with a current MDE lasting 8 weeks to 36 months as defined by the DSM-5 and confirmed by the MINI.
• Treated with an adequate dosage of a SSRI, SNRI, or bupropion during the current MDE for at least 8 weeks prior to Screening with the same, adequate dosage for the last 4 weeks. Minimum adequate doses are defined in the (ATRQ). The maximum dose allowed for paroxetine is 40 mg QD, for fluoxetine is 60 mg QD, and for sertraline is 200 mg QD.
• Have experienced an inadequate response to 1 to 3 courses of treatment with an antidepressant medication in the current episode, as defined as <50% improvement with an antidepressant medication at doses listed on the SAFER Interview Criteria: State versus trait; Assessability; Face validity; Ecological validity; and Rule of three Ps (pervasive, persistent, and pathological).
• Hamilton Depression Rating Scale-17 (HAM-D-17) ≥19 at Screening and Check-in (Day -1).
• BMI between 18.0 and 35.0 kg/m2, inclusive, and a minimum weight of 50.0 kg.
• Per the Investigator's judgment, able to meet all study requirements, including the confined/inpatient portion of the study, adherence with both approved ADT and study drug regimen, and completion of all assessments and all scheduled visits.
• Male patients of reproductive potential must be using and willing to continue using medically acceptable contraception, from Screening and for at least 2 months after the last study drug administration.
• Must be able to read, speak, and understand English and must provide written informed consent prior to the initiation of any protocol-specific procedures.

You may not qualify if…

• History or presence of clinically significant abnormality as assessed by physical examination, medical history, 12-lead ECG, vital signs, or laboratory values, which in the opinion of the Investigator would jeopardize the safety of the patient or the validity of the study results, including torsades de pointes, any bradyarrhythmias, or uncompensated heart failure.
• Chronic use of prescribed opioids (i.e., >120 days in a 6-month period) up to 6 months prior to Screening or any recreational use of opioids.
• Evidence of clinically significant hepatic or renal impairment, including ALT or AST >1.5 x upper limit of normal (ULN), bilirubin >1 x ULN, or endocrine laboratory values (including clinically significant thyroid parameters, i.e., thyroid stimulating hormone [TSH], triiodothyronine [T3], and thyroxine [T4]).
• History or family history of sudden unexplained death or long QT syndrome (measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle).
• Any 12-lead ECG with repeated demonstration of QTc ≥450 msec or a QRS interval >120 msec at Screening.
• History of clinically diagnosed hypotension requiring treatment.
• History or presence of any condition in which an opioid is contraindicated (e.g., significant respiratory depression, acute or severe bronchial asthma or hypercarbia, bronchitis, or has/is suspected of having paralytic ileus).
• No more than 3 prescribed doses of an opioid within the 6 months prior to Screening and no use at all within the last month.
• Use of an antipsychotic, anticonvulsant, or mood stabilizer, regardless of indication, within the 3 months prior to Screening.
• History of allergy or hypersensitivity to methadone or related drugs (e.g., opioids).
• Positive test for hepatitis B or HIV. Patients with a positive hepatitis C test may be considered for inclusion with approval from the Medical Monitor.
• Any current and primary psychiatric disorder, as defined as a condition that is the primary focus of distress and/or treatment, other than MDD.
• Any lifetime history of bipolar I or II disorder, any psychotic disorder, post-traumatic stress disorder, borderline personality disorder, antisocial personality disorder, obsessive compulsive disorder, eating disorder, intellectual disability, or pervasive developmental disorder.
• History in the past 12 months of a primary diagnosis of anxiety disorder or panic disorder not related to the current MDE.
• Current diagnosis of alcohol or substance use disorder, as defined by DSM-5, at Screening or within the 12 months prior to Screening. Patients with the following diagnoses within the past 12 months, however, may be included at the Investigator's discretion: mild alcohol use disorder, mild cannabis use disorder, and any severity tobacco use disorder.
• A confirmed positive result on the urine drug/alcohol screen at Screening or Check-in. If the urine drug/alcohol screen is positive at Screening, retesting or rescreening may be scheduled with prior approval from the Medical Monitor.
• Patients who, in the Investigator's judgment, are at significant risk for suicide. A patient with a Columbia-Suicide Severity Rating Scale (C-SSRS) ideation score of 4 or 5 within the last 6 months or any suicide attempt within the past year must be excluded, as should a patient with an ideation score of 4 or 5 or any suicide attempt at the Check-in or Baseline Visit.
• Patients with a 20% improvement between Screening and Check-in (Day -1) on the HAM-D-17.
• Patients who did not safely discontinue medications prohibited.
• Patients receiving new onset psychotherapy (individual, group, marriage, or family therapy) within 2 months prior to Screening or plans to start at any time during participation in the study.
• Patients who have received electroconvulsive therapy (ECT), repetitive transcranial magnetic stimulation (rTMS), or vagus nerve stimulation (VNS) or who have participated in a ketamine study within the last 6 months.
• Patients with any clinically significant neurological, hepatic, renal, metabolic, hematological, immunological, cardiovascular, pulmonary, chronic pain, or gastrointestinal disorder. Medical conditions that are minor or well-controlled may be permitted if they will not increase the safety risk to the patient or compromise interpretation of the safety or efficacy endpoints.
• Patients taking fluvoxamine or St. John's Wort.
• Patients who have participated in a clinical study with an investigational medication in the past 6 months, or who have participated in more than 4 clinical studies with investigational medications in the past 2 years.
