Summary

This study aims to examine the antidepressant efficacy of riluzole, employing a randomized, double-blind, placebo-controlled, adjunctive trial in treatment-resistant major depressive disorder (TRD).

Clinical Details

Official title: Efficacy and Tolerability of Riluzole in Treatment Resistant Depression

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Change in Montgomery and Asberg Depression Rating Scale (MADRS)

Secondary outcome:

Responders having at least a 50% improvement in MADRS compared to the baseline

Systematic Assessment for Treatment Emergent Events (SAFTEE-SI)

Detailed description: This study aims to examine the antidepressant efficacy of riluzole, employing a randomized, double-blind, placebo-controlled, 8 week trial of adjunctive trial in treatment-resistant major depressive disorder (TRD). Preclinical studies have shown riluzole to modulate Glu release and clearance, and to have potent neuroprotective properties, promoting neuro-resiliency. Other preclinical data now also show the drug to have antidepressant-like effects in rodent models used to screen for antidepressant activity. In addition, several small open-label clinical studies further suggest riluzole has antidepressant and anxiolytic properties, even in patients who do not respond to standard monoaminergic antidepressant and anxiolytic medications.

Eligibility

Minimum age: 18 Years. Maximum age: 65 Years. Gender(s): Both.

Criteria:

Group A inclusion/exclusion Inclusion Criteria: 1. Age 18-65 2. Written informed consent

3. Meets DSM-IV criteria (by Structured Clinical Interview for DSM-IV - SCID-I/P) for

MDD, current

4. Inventory of Depressive Symptomatology - Self-Rated (IDS-SR30) score of > 20 at

screening, baseline and start of double-blind phase (Phase 2) 5. May have a history of failure to respond to up to two FDA-approved antidepressants at adequate doses during the current episode for at least 8 weeks, and for inclusion into the Phase 2 subjects must have failed the 8-week prospective citalopram treatment. 6. Montgomery Asberg Depression Rating Scale (MADRS) score of 18 or higher at baseline and start of Phase 2. Exclusion Criteria: 1. Pregnant women or women of child bearing potential who are not using a medically accepted means of contraception (to include oral contraceptive or implant, condom, diaphragm, spermicide, intrauterine device, tubal ligation, or partner with vasectomy) 2. Patients who no longer meet DSM-IV criteria for MDD during the baseline visit 3. Patients who demonstrate > 50% decrease in depressive symptoms as reflected by the IDS-SR total score from screen to baseline 4. Serious suicide or homicide risk, as assessed by evaluating clinician A serious suicide risk will be considered an inability to control suicide attempts, imminent risk of suicide in the investigator's judgment, or a history of serious suicidal behavior, which is defined using the Columbia-Suicide Severity Rating Scale (C-SSRS) as either (1) one or more actual suicide attempts in the 3 years before study entry with the lethality rated at 3 or higher, or (2) one or more interrupted suicide attempts with a potential lethality judged to result in serious injury or death. 5. Unstable medical illness including cardiovascular, hepatic, renal, respiratory, endocrine, neurological, or hematological disease 6. The following DSM-IV diagnoses: substance use disorders active within the last six months, any bipolar disorder (current or past), any psychotic disorder (current or past) 7. History of a seizure disorder or clinical evidence of untreated hypothyroidism 8. Patients requiring excluded medications (see Table 3 for details) 9. Psychotic features in the current episode or a history of psychotic features, as assessed by SCID 10. Any investigational psychotropic drug within the last 3 months 11. Have failed 3 or more adequate antidepressant trials during the current Major Depressive Episode by MGH-ATRQ criteria. 12. Patients with a history of antidepressant-induced hypomania. 13. Patients with any evidence of clinically significant liver abnormalities, or any liver transaminase level >1. 5 X ULN at initial screening, or >5 x ULN during Phase 2 treatment. 14. Axis II personality disorders that are the primary purpose of treatment, or would interfere with a patient's safety or compliance. 15. Patients currently being treated for a respiratory disorder (including asthma or COPD) 16.
