Study Details
Study Description
Brief Summary
The main purpose of this study is to evaluate safety and efficacy of a single injection of MIJ821 in addition to standard of care (SoC) pharmacological anti-depressant treatment in participants with treatment-resistant depression (TRD)

Phase 2 |
Detailed Description
Approximately 56 participants will be randomized in a total of 20-25 centers worldwide. The trial consists of screening period of up to 28 days. On Day 1, eligible participants will be randomized to one of the treatment arms (low, medium or high dose of MIJ821) or placebo and receive study treatment administered as a single subcutaneous injection. Participant will remain at the clinic for at least 4 hours after administration of study treatment for safety observation including assessment of local tolerability by visual inspection of the injection area. Post-dose clinic visits will occur 24 hours post dose (Day 2), Days 8, 15, 22 and 29 to evaluate efficacy and safety. Efficacy assessments will include the Montgomery-Asberg Depression Scale (MADRS) and other clinical outcome assessments (COAs). Safety assessments include laboratory tests, ECGs, vital signs and physical examinations. In addition phone calls will be conducted 3 days after each on-site clinic visit with the exception of End-of-study (EOS) visit. EOS visit will be completed on site on Day 29. The total duration of the study is approximately 8 weeks (56 days), including screening.

Outcome Measures
Primary Outcome Measures
- Change from baseline in MADRS total score 24 hours after injection [Baseline and 24 hours after s.c. injection]
The Montgomery Asberg Depression Rating Scale (MADRS, SIGMA version) is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment: the test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition. The MADRS evaluates apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts and suicidal thoughts. The MADRS will be collected electronically by qualified personnel.
Secondary Outcome Measures
- Number of treatment-emergent adverse events (TEAEs), including AEs of special interest (AESIs) [Baseline up to 29 days]
Number of treatment-emergent adverse events (TEAEs), including AEs of special interest (AESIs) will be collected at all study visits. AESIs include dissociation, sedation, cardiovascular and respiratory effect, suicidality, memory gaps/amnesia, cystitis or lower urinary tract adverse events
- Pharmacokinetics (PK) of MIJ821 in plasma for AUClast [Baseline, 0.17 hour, 0.33 hour, 0.5 hour, 0.75 hour, 1, 1.5, 2, 4 and 24 hours post injection]
AUClast is the AUC from time zero to the last measurable concentration sampling time (tlast) (mass x time x volume-1)
- Pharmacokinetics (PK) of MIJ821 in plasma for Cmax [Baseline, 0.17 hour, 0.33 hour, 0.5 hour, 0.75 hour, 1, 1.5, 2, 4 and 24 hours post injection]
Cmax is the maximum (peak) observed plasma, blood, serum, or other body fluid drug concentration after single dose administration (mass x volume-1)
- Pharmacokinetics (PK) of MIJ821 in plasma for Tmax [Baseline, 0.17 hour, 0.33 hour, 0.5 hour, 0.75 hour, 1, 1.5, 2, 4 and 24 hours post injection]
Tmax is the time to reach maximum (peak) plasma, blood, serum, or other body fluid drug concentration after single dose administration (time)
- MADRS total scores [Baseline, Day 8, Day 15, Day 22 and 29]
The Montgomery Asberg Depression Rating Scale (MADRS, SIGMA version) is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment: the test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition. The MADRS evaluates apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts and suicidal thoughts. The MADRS will be collected electronically by qualified personnel.
- Dose-response relationship of MIJ821 [Baseline up to 24 hours]
Correlation between MIJ821 dose and change from baseline in the Montgomery Asberg Depression Rating Scale (MADRS) total score at 24 hours. The MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment: the test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition.
- Exposure-response relationship of MIJ821 [Baseline up to 24 hours]
Correlation between MIJ821 exposure and the Montgomery Asberg Depression Rating Scale (MADRS) total score at 24 hours. MADRS is a clinician-rated scale designed to measure depression severity and detects changes due to antidepressant treatment: the test consists of 10 items, each of which is scored from 0 (item not present or normal) to 6 (severe or continuous presence of the symptoms), for a total possible score of 60. Higher scores represent a more severe condition.
