Participants are eligible to be included in the study only if they meet all the following criteria:
- Are adult men or women between 18 to 65 years of age (inclusive) at informed consent
Have a primary DSM-5 diagnosis of MDD, with prominent symptoms of anhedonia confirmed by Structured Clinical Interview for DSM-5 Disorders, Clinical Trials Version (SCID-5-CT)
- The current episode must have started at least 3 weeks prior to screening visit but no more than 12 months before the screening visit.
- Have not failed 2 or more courses of antidepressant treatment in the current episode
- Have no more than a 3-point change in HAMD 17 between screening and baseline
- Have sufficient history or an independent report to confirm that symptoms are causing functional impairment or clinically significant distress
- Meet the blinded rule list based on clinical scale criteria
- Have body mass index (BMI) between 18-40 kg/m2 (inclusive)
- Are medically stable (in the opinion of the investigator and Sponsor/Sponsors delegate) based on medical history, vital signs, clinical laboratory tests, and 12-lead electrocardiogram (ECG) performed at screening and baseline
Agree to the following birth control:
- Nonvasectomized men must agree to use a condom with spermicide, if sexually active during the study, until 90 days after the last dose of study drug administration. No restrictions are required for a vasectomized man, provided his vasectomy was performed 4 months or more prior to the first dose of study drug. A man who has been vasectomized less than 4 months prior to the first dose of study drug must follow the same restrictions as a nonvasectomized man. Additionally, men must refrain from sperm donation during study treatment and for at least 90 days following the last dose of study drug.
Women of child-bearing potential (women not surgically sterilized and between menarche and 2 years postmenopausal) must have a negative serum pregnancy test at screening and a negative urine pregnancy test at enrollment and agree to use reliable birth control (eg, oral contraceptives or Norplant®; a reliable double barrier method of birth control (diaphragms with contraceptive jelly; cervical caps with contraceptive jelly; condoms with contraceptive foam); intrauterine devices; partner with vasectomy; or abstinence) during the study and for 10 days following the last dose of the study drug (BTRX-335140 or placebo). Women will be considered surgically sterile, if they have had tubal ligation, bilateral salpingo oophorectomy, or a hysterectomy.
Note: Abstinence will be allowed if, in the investigator's judgement, it is determined that the participant is reliable, that abstinence is the preferred and usual lifestyle of the participant, and that abstinence will be continued for the duration of the study including the 10 days (women) or 90-day period (men) following last dose of study drug as noted above.
- Or engaged exclusively in a non-heterosexual relationship
- Willing and able to give written informed consent to participate
- Able to understand and comply with instructions in English
- Are judged by the investigator to be reliable and agree to keep all appointments for clinic visits, tests, and procedures, including venipuncture, and examinations required by the protocol
Exclusion Criteria:
Participants will be excluded from the study if they meet any of the following criteria:
Have a history of any of the following DSM-5 disorders within the specified timeframe:
- Currently or in the past year: diagnosis of personality disorder, attention deficit disorder/attention deficit hyperactivity disorder, anorexia nervosa, or bulimia nervosa. Participants with comorbid generalized anxiety disorder, social anxiety disorder, or panic disorder for whom MDD is considered the primary diagnosis are not excluded.
- Lifetime: diagnosis of bipolar 1 or 2, schizophrenia, obsessive compulsive disorder, or post-traumatic stress disorder
- Have a history of substance or alcohol use disorder (AUD), per DSM-5 criteria, within the past year
- Are actively suicidal (eg, any suicide attempts within the past 12 months) or are at serious suicidal risk as indicated by any current suicidal intent, including a plan, as assessed by the Columbia Suicide Severity Rating Scale (C-SSRS) (score of "YES" on suicidal ideations item 4 or 5 within 3 months prior to Visit 1 (Screening) and/or based on clinical evaluation by the investigator; or are homicidal, in the opinion of the investigator

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Hamilton Depression Rating Scale (HAMD-17)
Time Frame: 8 weeks
|
Change from baseline to Week 8 in the HAMD-17 score; Minimum 0, Maximum 52; Higher scores mean a worse outcome
|
8 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Clinical Global Impression of Improvement (CGI-I) score
Time Frame: 8 weeks
|
The CGI-I is a clinician rating of how much the participant's illness has improved or worsened relative to a baseline state, a 7-point scale is used from 1=very much improved, 2=much improved, 3=minimally improved, 4=no change, 5=minimally worse, 6=much worse, 7=very much worse.
|
8 weeks
|
Change from baseline in Snaith-Hamilton Pleasure Scale (SHAPS) score
Time Frame: 8 weeks
|
The SHAPS is a self-report 14-item, instrument, developed for the assessment of hedonic capacity.
Participants score whether they experience pleasure in performing a list of activities or experiences.
Participants can rate the answers as "definitely/strongly agree", "agree", "disagree" or "strongly disagree".
"Definitely agree" will be rated 1, "Agree" will be rated 2, "Disagree" will be rated 3, and "Definitely disagree" will be rated 4. The participant's item responses are summed to provide a total score ranging from 14 to 56.
A higher total SHAPS score indicates higher levels of current anhedonia.
|
8 weeks
|
Change from baseline in Hospital Anxiety and Depression Scale (HADS) subscales (ie, anxiety subscale [HADS-A] and depression subscale [HADS-D]) scores
Time Frame: 8 weeks
|
The Hospital Anxiety and Depression Scale (HADS) is a 14-item self-report questionnaire with 2 subscales: anxiety and depression.
Each item is rated on a 4-point scale (0-3), giving maximum scores of 21 for anxiety and depression with higher scores indicating more severe symptoms.
|
8 weeks
|
Change from baseline in Hamilton Anxiety Rating Scale (HAM-A) score
Time Frame: 8 weeks
|
The HAM-A is a 14-item scale to measure severity of different anxiety-related symptoms in participants.
Each of the 14 items is rated by the clinician on a 5-point scale ranging from 0 (not present) to 4 (maximum degree) with a total score range of 0 to 52 where higher score indicates greater symptom severity.
|
8 weeks
|
Change from baseline in Sheehan Disability Scale (SDS) score
Time Frame: 8 weeks
|
The Sheehan Disability Scale (SDS) is a 3-item self-report questionnaire used to assess the effect of the participant's symptoms on their work (work/school impairment score), social life (social life/leisure activities impairment score), and family life (family life/home responsibilities impairment score).
Each item is measured on a 0 (not at all) to 10 (extremely) point scale with higher values indicating greater disruption.
|
8 weeks
|
Change from baseline to end of study in Clinical Global Impression Scale - Severity (CGI-S) scores
Time Frame: 8 weeks
|
The CGI-S is a clinician rating of the severity of the participant's illness.
The CGI-S is scored on a 7-point scale where a score of 1 indicates that the participant is normal, not at all ill, a score of 4 indicates that the participant is moderately ill, and a score of 7 indicates that the participant is among the most extremely ill participants.
|
8 weeks
|
Percentage of participants with a HAMD-17 response
Time Frame: 8 weeks
|
HAMD-17 response rate, where response is defined as ≥ 50% decrease in HAMD-17 total score from Baseline to Week 4 and Week 8. HAMD-17 is a 17-item questionnaire to capture symptom severity with a total score ranging from 0 to 52 with higher scores indicating more depressive symptoms.
|
8 weeks
|
Assessment of safety through the occurrence of TEAEs, SAEs, and adverse events of special interest (AESIs)
Time Frame: 8 weeks
|
Change from baseline in vital signs measurements, body weights, body mass index (BMI), clinical laboratory test results, C SSRS scores, Clinical Opiate Withdrawal Scale (COWS) scores; physical examination findings, ECG results, and ophthalmologic examination findings.
|
8 weeks
