Brief Summary:
Background: Although substitution therapy has been shown to be highly effective to retain opioid-dependent patients in treatment and reduce drug use, this population is afflicted by numerous conditions including depression. Unfortunately, studies published thus far have reported inconsistent or no difference in response between placebo therapy and antidepressants such as selective serotonin reuptake inhibitors. Objective: To assess the feasibility of Desvenlafaxine (DESV) administration among opioid-dependent subjects and explore its effect on depressive symptoms. Methods: Open-label pilot trial of 8 weeks of DESV 50-100 mg/day in 20 methadone-maintained individuals with comorbid depressive symptoms at the Centre hospitalier de l'Université de Montréal. Significance: This pilot study will lay down the foundation on which a larger multisite clinical trial could be conducted to examine DESV as new treatment for opioid-dependent population with comorbid depression.

Condition or disease Intervention/treatment Phase
Depression Opioid Dependence Methadone Treatment Drug: Desvenlafaxine Phase 4

Detailed Description:

To assess the feasibility, tolerability and acceptability of 8 weeks of Desvenlafaxine (DESV) administration among opioid-dependent subjects in a methadone-maintenance program, we will collect detailed information on compliance to DESV treatment, side effects, methadone plasma levels, methadone dose changes and QTc measures.

To explore the effects of DESV on depressive symptoms among opioid-dependent subjects on methadone-maintenance treatment. The severity and symptoms of depression will be evaluated by using the MADRS, the HRDS, and the CGI scale.

To explore the effects of DESV on substance use, anxiety, craving, quality of life and suicidal risk.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Desvenlafaxine
  • Open-label pilot study
  • Desvenlafaxine will be administered during 56 consecutive days
  • Desvenlafaxine will be administered in the morning at a 50 mg dose during weeks 1 and 2, and at 50-100 mg doses (based on the study psychiatrist's judgment) during the 6 following weeks.
 Drug: Desvenlafaxine
All subjects will receive 50 mg of the medication during week 1 and 2, then 50-100 mg (based on the psychiatrist judgment) for the following 6 weeks. Subjects who experience significant adverse reactions with the 100mg dose during weeks 2 to 4 could return to the lower dose of 50 mg if judged clinically appropriate by the study psychiatrist.
Other Name: PRISTIQ


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Tolerability: Systematic Assessment for Treatment Emergent Events (SAFTEE) [ Time Frame: 8 weeks ]
    Safety and adverse effects with the Systematic Assessment for Treatment Emergent Events (SAFTEE)


Secondary Outcome Measures :
  1. effect of Desvenlafaxine on depressive symptoms [ Time Frame: 8 weeks ]
    Responders will be determined by a 50% reduction in (Hamilton Depression Rating Scale) HAM-D scores, and remitters will be determined based on scores of ≤7.

  2. effect of Desvenlafaxine on depressive symptoms [ Time Frame: 8 weeks ]
    Responders will be determined by a 50% reduction in the Montgomery-Asberg Depression Scale (MADRS) scores, and remitters will be determined based on scores of 10.

  3. Response to treatment [ Time Frame: 8 weeks ]
    A favorable response will be defined as a score of 1 or 2 (very much or much improved) on the Clinical Global Impression CGI-I subscale

  4. Feasibility: Proportion of persons screened who are eligible and enrolled [ Time Frame: Baseline ]
    Proportion of persons screened who are eligible and enrolled

  5. Treatment adherence [ Time Frame: 8 weeks ]
    Compliance will be evaluated at each in-person follow-up visit. Treatment adherence will be calculated as the total number of tablets dispensed minus the number returned, divided by the total number of tablets dispensed

  6. Effect of Desvenlafaxine administration on QT/QTc interval prolongation [ Time Frame: 4 weeks ]
    It will be assessed by electrocardiograms (upper limit for safety should be 500ms).

  7. Feasibility: Proportion of scheduled study visits completed and biological samples collected [ Time Frame: 8 weeks ]
    Proportion of scheduled study visits completed and biological samples collected

  8. Potential for drug interactions between methadone and antidepressants - Effect of Desvenlafaxine on methadone serum level (pharmacokinetic variability) [ Time Frame: 4 weeks ]
    Change from baseline in methadone serum level. We will assessed the methadone serum level at baseline and after a month of treatment.

  9. Methadone dose adjustments [ Time Frame: 2 - 4 weeks ]
    Change from baseline in methadone dose. Each dose adjustment occurring during the trial will be noted at each follow-up visit


Other Outcome Measures:
  1. Substance use [ Time Frame: 8 weeks ]
    number of days of substance use as assessed with The Time Line Follow-Back (TFLB), urine-drug testing and alcohol-breathalyzer testing.

  2. Effect of Desvenlafaxine on anxiety [ Time Frame: 8 weeks ]
    Change from Baseline in anxiety and mood. It will be assessed with the Hamilton Anxiety Rating Scale (HAM-A)

  3. Effect of Desvenlafaxine on blood pressure and heart rate [ Time Frame: 8 weeks ]
    Change from Baseline in Systolic Blood Pressure and heart rate

  4. Effect of Desvenlafaxine on opioid craving [ Time Frame: 8 weeks ]
    Assessed with the abbreviated Heroin Craving Questionnaire (HCQ) - Change from Baseline in Craving.

  5. Effect of Desvenlafaxine on quality of life [ Time Frame: 8 weeks ]
    Change from baseline in Quality of life. It will be assessed with the World Health Organization Quality of Life questionnaire (WHOQOL-BREF)

  6. Effect of Desvenlafaxine on disability [ Time Frame: 8 weeks ]
    Change from baseline in disability. It will be assessed with the Sheehan Disability Scale (SDS)

  7. Effect of Desvenlafaxine on suicidal behaviour [ Time Frame: 8 weeks ]
    Change from Baseline in suicidal behaviour. It will be assessed with the Columbia-Suicide Severity Rating Scale (CSSRS)

  8. Effect of Desvenlafaxine on testosterone level [ Time Frame: 4 weeks ]
    Change from Baseline in testosterone.
