ClinicalTrials.gov Identifier:
NCT00682591
First received: May 20, 2008
Last updated: February 3, 2009
Last verified: February 2009
  Purpose

Prospective, longitudinal multi-center study performed in 15 participating substitution centers in Germany.

Aims:

- Primary objective: To compare the impact of the different substitution drugs (methadone, buprenorphine, and suboxone) on the neurocognitive, emotional, and quality-of-life-related tolerability in opioid dependent patients under HCV treatment.

- Secondary objective: To investigate if IFN therapy impairs efficacy (with respect to e.g. retention rates, concomitant drug use and in particular neurocognitive function) and tolerability of agonist maintenance treatment with methadone, buprenorphine, or suboxone


Condition

Time Perspective: Prospective
Official Title: Evaluation of Neurocognitive Performance, Quality of Life, and Emotional State in Drug Substituted Patients (Methadone, Buprenorphine, Suboxone) Under Hepatitis C Therapy (Peginterferon Alfa and Ribavirin)

Study Population

Outpatients with chronic hepatitis C infection and drug substitution therapy (methadone, burpenorphine, suboxone)

Criteria

Inclusion Criteria:

  • Opioid-dependent patients on current stable agonist maintenance therapy (for at least 6 months prior to study enrolment) with methadone, buprenorphine, or suboxone.
  • Patients need to be infected with chronic hepatitis C and must have indication for therapy with peginterferon alfa and ribavirin.
  • Patients with informed written consent with respect to a follow-up of psychiatric side effects and in particular neurocognitive performance.
  • Patients with baseline monitoring of emotional state and neurocognitive performance.

Exclusion Criteria:

  • According to SPC
  • According to legal requirements reg. drug substitution therapy (BTMVV)
  • Insufficient knowledge of the German language or cognitive impairment (due to the indispensable application of questionnaires and the TAP, Test Battery of Attentional Performance).
  • Age under 18 years or over 65 years
  • coinfections such as hepatitis B virus or human immunodeficiency virus
